  Chapter 84 Air Pressure (4K)

   "Board."

  Jiao Cheng waved his palm, and everyone boarded three wooden boats.

  Di Wu stood at the bow of the boat, removed the iron chains tied to the canoe, and asked the other two to pick up the oars and paddle the canoe to sail along the wall of the cave.

  I moved out an open jar from the bottom of the boat, and dipped a brush into the jar.

  As the wooden boat sailed forward, Di Wu used a brush to paint an intermittent dotted line on the high part of the wall.

  ‘Is this .phosphor? '

   Li Ang narrowed his eyes, and a dim green light shone faintly on the wall of the cave that had been smeared with brushes.

  ‘The cave in front also has fainter fluorescent traces, which proves that Jiao Cheng and others are not here for the first time—they have explored many times in advance and used fluorescent powder to mark the channel.

  Because the highlighter fades over time, apply multiple coats.

   And this dark river, no matter the top of the cave or the height of the wall, has erosion marks formed by long-term water erosion.

   It proves that the water level is very high most of the time, and now the water level has dropped to allow the canoe to pass. '

  Facts are just as Li Ang expected, the three wooden boats continue to sail forward, and whenever they encounter a fork in the road, they choose the path according to the fluorescent marks left before.

  The shape of the underground river is controlled by geological structures and cracks. Factors such as seasons, rainfall, and geological collapse on the surface may affect the shape of the underground river. The terrain is extremely complex.

  In the same underground aquifer, there are many interconnected underground rivers, either swift or slow, upward or downward, with countless forks. Once lost, the consequences will be disastrous.

  In the depressing space, it seems that only the sound of water flow remains,

  The crowd held torches, breathed heavily in the humid air, and kept wiping the water drops dripping from the top of the cave onto their heads and faces with their hands.

   I don’t know how far I sailed, but when Di Wu ran out of the second can of fluorescent powder, I finally saw the fire at the bend of the river ahead.

"arrive."

  Di Wu breathed a sigh of relief, and steered the canoe to sail towards the fire.

  There is a relatively gentle river beach. There are seven or eight torches planted on the river beach, and there are more than a dozen tattooed men standing there—they are all wearing hard leather armor, taking into account both defense and mobility.

  Pu Dao hung on his waist, a metal shield in his hand, and a crossbow like Jiao Cheng hung on his back.

   It's not like the green-skinned hooligans guarding Pingkang Square, but more like a group of desperadoes.

   "Jiao Da."

   "Jiao Da."

  The men with tattoos surrounded him and helped Jiao Cheng off the canoe.

  Li Ang got off the boat together, and noticed with his eyes that there were many supplies piled up on the river beach.

  Hook claws for climbing high places; kerosene for lighting; steel nails and sledgehammers for digging boulders; hemp rope, bamboo ladder, compass

  In the distance of the river beach, one can faintly see a cliff, and two huge shadows crawling on the ground below the cliff.

That is

  ‘Tomb-slayer beast? '

Li Ang squinted his eyes and saw two shadows below the cliff in astonishment. They were two stone tomb-slayer beasts with human faces and beast bodies. They were nearly four meters high. The whole body was pitch black and there were no paintings. The lifelike human heads opened their mouths and showed their fangs. teeth.

  The lower part of the beast's body is covered with sharp thorns and strange and inexplicable diamond-shaped patterns.

   "Let's go."

  Jiao Cheng, supported by his subordinates, walked towards the location of the tomb-slayer beast. During their conversation, Li Ang also learned the names of the two sword repairmen.

  Fan Guangyu, Zhu Yuyin.

  The people carried the packages and walked towards the cliff. As the distance got closer,

  Li Ang saw an open tall stone gate between the two tomb-suppressing beasts, and behind the stone gate was a slanted upward passage.

  In the depths of the tunnel, there was a continuous sound of howling wind.

   The booming sound echoed back and forth on the corridor wall, like the roar of some kind of wild beast.

  Jiao Cheng and the others held torches and crawled up the corridor. Halfway through the climb, they stopped collectively and took out a pair of strangely shaped breathing masks from the package.

  The object consists of three items: a mask, a hose, and a backpack.

  The outside of the mask is made of bamboo, and the inside is a layer of jelly like fish foam. The contour of the mask can fit the mouth, and there are ropes at the back to fix the ears to prevent the mask from falling.

  The right side of the mask is connected to the cylindrical stump contained in the metal backpack through a hollow wooden vine.

   "This is a fourth-class monster, the stump of the banyan tree of Zhangdao Ghost Banyan, and the aerial roots growing from the stump."

  Jiao Cheng put on the backpack with the help of his subordinates, and said to Li Ang slowly: "After wearing it, you can breathe underwater for a quarter of an hour.

   is an important tool for the survival of Zhang Islanders in the endless sea.

   I spent 30,000 guan to buy these things at the ghost market. "

   Breathe underwater?

   Li Ang's guess became clearer and clearer, especially after noticing that the two sword repairmen were also wearing backpacks.

  He took Di Wu's extra metal backpack from the team, carried it on his back, and put on a breathing mask for himself.

  The team climbed up the corridor again. The further they went, the more violent the strong wind could feel.

  The air became thinner.

  Li Ang subconsciously breathed harder, followed behind Di Wu and the others, and climbed out of the narrow corridor.

   This is an extremely spacious underground hall, which is circular in shape as a whole.

  The ground in the center of the hall is flat and tidy, without any gravel. With the light of the fire, one could faintly see a bronze stone door embedded in the floor in the middle of the hall.

  The walls of the hall are full of honeycomb holes with a diameter of more than one meter.

   Above each hole, there is a thick hollow metal plate with different patterns on the metal plate.

  The strong wind gushed out of those holes, sucking away the air in the hall like a vortex, reducing the air pressure in other places.

   Some pale white air blades can be vaguely seen in it.

   It should only exist in high places, the wind of heaven and earth.

   Astral wind can not only erode solid metal, but also weaken the strength of monks, making monks including body training warriors unable to exert their original abilities.

   No wonder Jiao Cheng's subordinates suffer from high-altitude cerebral edema for no reason, no wonder Jiao Cheng's own leg injury is so weird.

   Li Ang pursed his lower lip slightly, and his eyes were attracted by the dome of the hall—two lines of extremely deep writing were engraved there.

   "The fairy caresses my head, and my hair is tied for longevity.

  Bones form hills and mountains, what a crime the common people have. "

  Li Taibai's poem?

  Li Ang's heart skipped a beat, but Jiao Cheng said, "How long?"

   "It's less than half a quarter of an hour."

  Fan Guangyu, one of the sword cultivators, said in a low voice: "These winds are formed by formations and driven by the 100-meter waterfall in the underground river.

  Once the water flow slows down, the force of the wind will naturally decrease. "

   "In time."

  Jiao Cheng breathed a sigh of relief, and muttered to himself, "It's too late."

   Is there time to open Li Taibai's tomb?

  Li Ang's thoughts changed sharply. Li Taibai was a poet of Yuchu.

Li Taibai, who had reached the peak in poetry and sword, began to travel around the world, visiting famous mountains and rivers, and making friends with friends. Along the way, there were many teenagers and young monks who followed him, listened to his poems, and learned his sword. Although Li Taibai did not accept it. Any disciple, but did not reject anyone.

  If things go on like this, Li Taibai will become a poet and sword fairy with a complete life after his death, and even after thousands of years, people will praise his deeds.

  However, at the age of fifty, after he returned from traveling in the depths of the 100,000 barren mountains, he went to Mount Taihao alone with his sword.

   No one knows who he saw there or what he did, only that he went literally crazy when he came back.

  He no longer pays attention to anyone, does not talk to anyone, even his former confidants and friends or even family members and friends.

  He went to Nanzhao and used flying swords to cut down giant trees and build giant boats. Anyone who tried to interrupt his boat building behavior would be killed by a sword.

  Even a cultivator in the Candle Sky Realm couldn't block a single strike.

  After the huge boat was built, he sailed to the endless sea alone. There was no news for twenty years.

   It wasn't until twenty years later that news spread around the world that they saw a taciturn, skinny old man with a sword haunting him. The saber fastened is exactly Li Taibai's sword.

   Various forces moved after hearing the news, trying to find him, but they were always one step behind—it was rumored that he had built an astonishingly large tomb for himself in the depths of the underground in many places,

   And hid the secrets he got in the endless sea, every sword he used, and every sword manual he wrote down in the tombs.

   And in the last real tomb, step into the realm above Linyuan Realm and become a real immortal.

  The tomb of the sword fairy may not exist, or it may really exist-ordinary people may not know the answer in their entire lives.

   "It's half a quarter of an hour."

   Another swordsman, Zhu Yuyin, suddenly opened his eyes. Sure enough, the airflow gushing from the hole in the wall weakened a lot.

  The aura of heaven and earth lingering in the hall also became extremely dim, as if it would disappear at any moment.

   "Sun Jiu, Zhang San, you go first."

  Jiao Cheng's eyes flickered, and he waved his palm, his voice became muddy and deep because of the obstruction of the breathing mask, "Be careful."

  Two tattooed men in leather armor walked out of the team. They wrapped iron ropes around their waists, leaned back to each other, bent over, held metal shields in front of them, and rushed to the center of the hall quickly.

  dangdangdangdang—

  The strong wind of heaven and earth slashed on the thick metal shield, cutting off a corner of the shield directly.

  The two tattooed men kept their bodies as low as possible and ran for fifty steps. Among them, the taller one was accidentally cut off by the wind on his left arm, and subconsciously wanted to cover the wound.

   As a result, the shield deflected, and half of the neck was cut off by a strong wind, and blood flowed profusely in an instant, and he fell to the ground.

  His death also left his back companion without cover. The back was instantly torn into countless wounds by the strong wind, and the leather armor fragments burst and merged into the howling wind.

   The Xiantian Gangfeng revolves around the middle of the hall, and no flaws can be seen.

  Jiao Cheng's subordinates immediately pulled the iron cable close to the ground, and pulled the surviving Zhang San back before the iron cable was also cut.

Blood gushed out from Zhang San's body, Jiao Cheng glanced at Li Ang, Li Ang frowned slightly, opened the medicine box, and sewed up Zhang San's wound with silver thread - he didn't have Jiao Cheng's ability to endure the pain, so he kept howling miserably. Others had to hold his hands and feet and cover his mouth.

   "No, no"

  Sword cultivator Fan Guangyu murmured, "Everyone says that the Sword Immortal went completely mad after returning from the Endless Sea, but the Clothes Tomb he built always left a way to the tomb.

   Regardless of whether this way of life is what he wants to set up for his descendants or the heirs of the sword, it must exist.

  The congenital wind can crush steel and suppress monks.

   Apart from the power source—that is, the underground river waterfall whose location is unknown, there are almost no weaknesses.

  There must be a shortcut.”

   "Could it be a formation?"

  Another sword cultivator, Zhu Yuyin, said in a low voice: "The formation that can generate the innate wind can only be arranged by monks in the Candle Sky Realm and the Abyss Realm.

  The metal plates above the holes on the wall have different patterns, and there are as many as sixty-four kinds in total. It should correspond to the sixty-four hexagrams. "

  His eyes flickered, and he muttered to himself as if he had discovered a treasure: "Kun is the earth, the mine is restored, the land is in the lake, and the earth is peaceful."

  Zhu Yuyin's words were forcibly interrupted,

   Sun Jiu's body, which had fallen in the center of the hall, was lifted up by the whirling wind and fell on a certain square brick.

  The square brick suddenly sank, and a series of rumbling sounds came from the wall of the hall.

   Hoo!

  The gang wind gushing out from the hole in the wall instantly became fierce and violent,

  The air blade shot out directly cut a man with tattoos standing slightly forward into several sections,

  The gushing blood was swept by the strong wind and turned into a blood mist before it landed.

"retreat!"

  Jiao Cheng shouted loudly, and was about to retreat towards the corridor where he came.

  But with a loud bang, an extremely thick dragon-breaking stone fell down inside the entrance of the slanting passageway, blocking the escape route.

  The back road is blocked, and the vortex in the hall is still expanding and accelerating.

  The rubble on the edge of the hall was constantly being rolled up by the strong wind, spinning rapidly with the vortex, hitting everyone like bullets,

   Another man who was too late to lift his shield was hit in the forehead by a high-speed stone, and his head burst and died.

  dangdangdangdangdang—

  The finely crushed stones and strong winds are constantly eroding the shields that everyone smashed on the ground,

  Zhu Yuyin nervously glanced at the wall, the patterns on the hollowed-out metal plates, still muttering to himself, "The five ridges are the wind, the six ridges are the water, and the water helps the wind.

  I see, the hollow metal plate above the hole, put it down! "

  He pulled the two of them up from the ground and asked them to hold their shields, sticking to the edge of the cave hall, and walked towards the cave on the mountain wall.

   Click!

  One of them pinched the edge of the hollow metal plate. There was a chute between the metal plate and the hole below. He pulled hard and successfully pulled the hollow metal plate down.

  The metal plate seemed to be hollowed out, but after it was put down, there was a rolling sound of a spherical object behind it,

  The airflow gushing out from that hole and the adjacent hole has also weakened a lot.

   succeeded.

  Zhu Yuyin smiled, and the next second—

  Boom!

   A more violent wind gushed out from behind the hollowed-out metal plate, instantly crushing the tattooed man beside him into minced flesh.

  The wind increased instead of decreasing, and Zhu Yuyin and another survivor had to lie on the ground to avoid the strong wind.

what happened? Why did the wind become more violent after the metal plate was put down?

  Like everyone else, Li Ang, who was holding a shield to avoid the strong wind, glanced around and suddenly noticed one thing—all the holes on the mountain wall seemed to be in pairs.

  Just now, after Zhu Yuyin had someone put down the metal plate, there was a rolling sound of a spherical object first behind the hole, and the wind first weakened and then strengthened.

  “.”

   Li Ang took a deep breath, the escape route of the corridor was blocked, and the vortex of the wind was still expanding, so he had to find a way out.

  He hammered the back of Di Wu in front, and shouted loudly: "Go and lift up that closed metal plate!"

   Card, stuck point failed.
