Starting Off Survival With A Small Treehouse

Ma Hongwei and Zeng Tao could hear the sound of Xu Xin's watch.

Both of them were also taken aback, and turned to look at Xu Xin's watch.

"Underground? Did you drill a hole from the ground?" Zeng Tao exclaimed.

"Underground..." Ma Hongwei frowned immediately.

The sky and the earth are fine, but the underground...

His ability doesn't seem to be able to handle this situation.

Xu Xin thought a lot in an instant.

It was drilled from the ground... This possibility should have been considered long ago!

Although there is a safe zone around the tree house, the roots will protect the surrounding land from encroachment, but…

That might only be useful to those low-level wild mutant animals and plants!

At this time, the world tree has not really grown, and the root system is at its most vulnerable.

Could it be that... the other party wants to destroy the root system of the World Tree? !

No...probably not.

The root system of the World Tree is very wide, and it can even affect the entire area of ​​188. They can't destroy it at all.

Therefore, they should be the body that wants to destroy the world tree!

"That's right, it's coming in from the ground!"

Qin Fu was a little out of breath, obviously running: "Just to the east of Crystal City, I found a cave that was dug out of the ground. The depth is about five meters underground. This cave has gone deep into Crystal City for about five or six hundred meters. !"

A cave about five meters underground with a length of five or six hundred meters!

Only caves?

"Are there only caves?" Xu Xin immediately asked, "Aren't there any beasts or mutated creatures?"

"When I excavated, it was gone." Qin Fu responded, "There is only one cave with a diameter of less than one meter. It is very narrow. If people want to enter, they may have to crawl. Creatures shouldn't be too big."

"Where is the location?" Xu Xin asked again.

"It's just a few meters outside of Crystal City, but the entrance of the cave is flat and has been filled, and there are no traces at all."

The entrance, is it just outside the Crystal City...

The trees near Crystal City had all disappeared. If it wasn't for the tree planting this time, Qin Fu might not have noticed it at all.

"According to my observation, this cave was definitely dug out just now. Judging from the traces in the soil, the guy who dug the cave probably just left not long ago."

"That is to say... last night?"

"No, this morning!" Qin Fu asserted, "This cave was definitely newly dug this morning!"

"...But, I don't know who dug it." Xu Xin thought of something, and her face became slightly ugly.

"Yes." Qin Fu seemed to stop, took a few breaths, and sighed, "Here comes another one."

"Another burrow?" Xu Xin's eyes were fixed, "Where are the mutant creatures? Are there any mutant creatures digging?"

"No, there is only one long hole, this one is even longer, there is..."

Qin Fu started to run again, and after running for more than ten seconds, he stopped, gasped slightly, and said, "It's seven or eight hundred meters!"

Seven or eight hundred meters...

The radius of Crystal City is only about 2.5 kilometers, and seven or eight hundred meters is considered to be a relatively deep position in Crystal City!

"Look at it this way, don't worry too much." At this moment, Zeng Tao said, "After only digging a few hundred meters, it means that they can't bear it. If they can bear it, shouldn't they just dig to the bottom?" Are you destroying the World Tree inside?"

"No." Xu Xin directly denied her statement, "Seven or eight hundred meters is already very deep. If it will be affected, it should have been affected long ago."

If you can reach the position of seven or eight hundred meters, you will definitely be able to go deeper, directly enter the center of Crystal City, and reach the position of the World Tree.

"Huh? Then what are you talking about? Why did you go back after digging halfway?" Zeng Tao wondered, "Give up halfway?

"

"I found another one." At this time, Qin Fu's voice came out of the watch again, "This should be the last one. This one is also five or six hundred meters long, and it's about the same length."

"Look?" Zeng Tao suddenly felt a little proud, "They all stopped at this distance, doesn't that mean that they can't get in here? It must be like this."

Xu Xin glanced out the window.

What Zeng Tao said is not unreasonable, but...

At this time, Ma Hongwei sat in front of his test bench, put down the blueprint in his hand and said, "If there are only three caves, could it be just a test?"

"Test?" Zeng Tao looked back at Ma Hongwei, "What do you mean?"

"I also have this idea." Xu Xin nodded slightly, "This is obviously a temptation. If you want to attack the World Tree...what's the use of just a few such narrow passages?

These passages, perhaps just the other party came to test whether they can dig holes into the Crystal City from the ground and get close to the World Tree. "

"I also think so."

On the voice side, Qin Fu spoke again.

"Why do you all think so?" Zeng Tao pouted.

"After going a few hundred meters deep, those spies have confirmed that they can approach the World Tree from the ground, so they left." Xu Xin explained the situation in the [Explorers] group while explaining.

As for why they went back at a distance of seven or eight hundred meters, Xu Xin believed that the closer to the World Tree itself, the more developed and dense the root system of the World Tree should be, and the difficulty of digging would also increase exponentially.

"Need, more diggers." Xu Xin narrowed her eyes and looked out the window, "So, they are going back to invite a large army."

"Ah?" Zeng Tao immediately ran to the window to look out, "You mean... a large army will attack soon?"

"It's possible."

In the group of explorers, everyone saw the message from Xu Xin.

Wang Lei: "Grass, did you send a big mouse over here!"

Zhao Xiaochuan: "Drilling holes underground... I thought the ground was protected by the roots of the World Tree and the tree house, which was the safest..."

Qin Yunlong: "What if this is really dug in from the ground?"

Ji Zhaoyang: "Let's gather and discuss under the World Tree."

Qi Xuefei: "Okay."

Wen Guixin: "Wait for me, go back right away, I'm a little far away! I'm looking at these mutated creatures that have surrendered!"

Xu Xin wanted to leave immediately.

"I'm going too!" Zeng Tao immediately wanted to go with Xu Xin.

She can't wait to escape from here.

"I won't go." Ma Hongwei waved his hand, "I can only be in charge of the guys above the ground and in the air, and the guy who digs underground...I can't handle it, why don't we do more research."

Xu Xin nodded.

He doesn't like crowds, and generally he won't participate unless necessary.

"Let's go."

Xu Xin and Zeng Tao got out of the tree house and came to the edge of the World Tree.

Looking at the world tree again, it is still growing, but the speed is not as fast as before, and it can't be seen without careful observation.

Except for Wen Guixin, who was a little far away, and the person involved, Qin Fu, everyone else had arrived.

Even Lou Feier and Jin Yue are there.

After all, Lou Fei'er was also in the group and could see Xu Xin's news.

At this time, Jin Yue has completely changed her appearance.

The figure is taller and straighter, and the skin is also supple.

Seeing Xu Xin looking at her, she nodded slightly, indicating that she had fully recovered.

And at this time, Qin Fu came back.

He walked directly towards the place where the crowd gathered under the World Tree.

Wen Guixin followed closely behind.

"Qin Fu, tell me clearly what you found out."

"Okay." Qin Fu nodded, "It's like this..."

Qin Fu described the situation of the cave in detail again.

"We really need to seriously think about countermeasures." Ji Zhaoyang said in a deep voice, "Underground intrusion is not easy to stop."

"Drilling holes in the ground..." Wang Lei stepped on the ground, "This alien invader really uses all kinds of tricks. Is this trying to steal a house directly from the ground?"

"Aren't they going back to call the army?" Zhao Xiaochuan worried, "Isn't that coming soon? We must think of a way as soon as possible!"

"No." Xu Xin expressed her thoughts, "Perhaps, not so soon."

Everyone else looked at him.

"My idea is that underground invasion is not so easy to carry out secretly." Xu Xin explained, "After all, once there are more mutant creatures in the underground, it is easy for us to discover their movements. Especially I."

Xu Xin possessed the map ability, and a large area of ​​red dots appeared around him, how could he not notice it.

"That's right." Ji Zhaoyang also echoed, "Besides, there are a large number of mutant creatures who have taken refuge in us at the edge of our crystal city. Only one or two of them may not move, but if the enemy appears in a large area, they are impossible Indifferent. If you want to attack on a large scale, it is impossible not to be exposed.”

"That's true." Wen Guixin nodded, "I went to see the group of mutant creatures, they are all in high spirits now, and they are very friendly to me, and they also expressed their willingness to protect Crystal City .”

"Then what if we come from a farther place?" Qi Xuefei asked.

"This is indeed a possibility." Xu Xin took the words and said, "However, what I want to talk about is another possibility. That is... the underground army may appear together with the ground and air army."

Xu Xin's words caused everyone present to change their expressions slightly.

"If it were me, I would do this. When a large number of mutated creatures appear together, some of the mutated creatures will burrow into the ground, so they won't be conspicuous.

These mutated creatures marched towards the world tree from the ground, while the enemies on the ground and in the air were responsible for attracting attention. "

"We have prepared a lot of ways to deal with enemies on the ground and in the air. There are many tree houses with heavy crossbows, and the anti-air ability is also good. Combined with Miss Gui Xin's ability, the herd of beasts is not to be feared."

"But..." Xu Xin pointed to the ground and said, "When we were happy to repel the enemies in the air and on the ground...the enemies in the ground might have destroyed the world tree. If it weren't for Qin Fu's ability, this might be ours. Encountered."

Xu Xin's words silenced the surrounding people.

Everyone, including Xu Xin herself, felt a chill.

Indeed.

If it wasn't for Qin Fu's ability, if the other side had really arranged this way, then they might have been robbed without knowing it.

"Very likely." Ji Zhaoyang looked at the World Tree beside him, "Also, digging a hole from the ground to the World Tree may be able to destroy the World Tree better. Perhaps underground attack is really their real means."

"Why?" Wang Lei was a little puzzled, "The root system of the World Tree is so developed, it's useless if they destroy a few roots, it still needs to be severely damaged, so it's not as good as the ground, and the soil needs to be dug underneath."

"First of all, there is a crystal city on it. It's not easy for them to come in." Ji Zhaoyang patted the World Tree, "Secondly, this World Tree is also a tree house, so it should... also have a tree house core."

Treehouse Core…

Yes.

Everyone reacted immediately.

Where is the treehouse core?

Half-buried in the soil below the trunk hollow.

If it invades from the ground...

Perhaps the core of the tree house of the World Tree can be dug away directly!

In that way, there is no need to destroy the world tree. The world tree that lost the core of the tree house will naturally wither and wither, and then die.

The treehouses that have lost their treehouse core

What will happen, but I am all too familiar with it.

And it would be very difficult to destroy the World Tree from the ground.

Simply doing some damage will not kill the tree house. If you want to destroy the tree house from the ground, you need to cut the tree house directly.

But the world tree is so thick...

Xu Xin looked at the World Tree again.

Now the diameter of the trunk of this world tree is probably more than ten meters.

Incomparably thick and tall towering giant tree!

It is impossible to think about breaking this tree off the ground.

From this point of view, Xu Xin's conjecture that the underground is the main attack is becoming more and more reasonable.

but…

Xu Xin glanced at the World Tree again.

Isn't this world tree a little...too thick?

The world tree in Shi Wanyun's memory is only this thick, right?

And this world tree seems to need a few more days to grow.

Is this tree stronger than the world tree of those alien invaders?

…When Yingying was here before, she should have asked a few more questions about this World Tree.

All he knows now is that this world tree is the most successful tree house seed in their experiment.

"Now we know, how can we solve it?" Wang Lei pointed to the ground, "We don't seem to have any way to deal with the mutated creatures that drill underground, right?"

Indeed not.

Everyone frowned, thinking about how they should respond if Xu Xin's conjecture came true.

At this moment, Lou Feier tugged at Xu Xin's clothes, and whispered: "Your pangolin, can't it also drill holes? I went to see it this morning, and the two small ones have grown to be very big. .Can they come in handy?"

Concubine Pangolin and those two little guys?

yes!

Concubine Ai should have been promoted to a mid-level mutant creature by now!

"Xu Xin, can your pangolin pull out a few burrowing mice from the ground?" Wen Guixin asked, "If possible, I will infect the ones I picked out and let them burrow in again..."

Hearing this, the eyes of the people around them lit up.

Let that infected guy infect the entire underground army!

Let them all die in the ground!

"Good idea!" Wang Lei clapped his hands, then laughed, "Haha, with Sister Gui Xin here, it's really easy to deal with the herd of beasts!"

Xu Xin and Ji Zhaoyang also looked at each other, then nodded.

"However, we can't just take it lightly." Xu Xin said, "This doesn't solve all the possibilities."

"Yes, the underground pathways they dug up may not be connected, and it may not be so easy to infect a large area." Ji Zhaoyang also said, "Also, beware of the very powerful, Wen Guixin cannot infect existence in a short time."

"Then we should..."

"Dig ditches." At this time, Qi Xuefei proposed a plan, "Dig a circle of deep and wide enough ditches around the world tree. In this way, it may be able to stop the pace of underground digging. If they dig out and enter We can also attack into the ditch. The tree house heavy crossbow can also come in handy.”

"Good way!"

"It makes sense!"

"Just dig deep enough and they'll have to come out of the ditch!"

"Well, at least it can slow down their movements and make it easier for me to infect." Wen Guixin also agreed, "Just how deep should it be?"

"The cave they dug is at a depth of five meters. UU Reading www.uukanshu.com" Qin Fu said at this moment, "We dig ten meters? Fifteen meters?"

"So deep..."

Ten meters, that is the height of a three-story building.

Fortunately, they have advanced tools, so digging is easy.

There are also three pangolins that dig super fast.

"Well, you can try it." Xu Xin thought for a while, "However, the root system around the World Tree is probably very close to the ground. If we don't want to destroy the root system of the World Tree, we need to do it at a farther place."

But if it is too far away, the amount of work to dig a circle of deep ditches will be too large.

This distance needs to be grasped by oneself.

"In this case, let's act quickly!" Zhao Xiaochuan took out the shovel directly, "I don't want the core of the world tree to be taken out!"
