A swarm of heavy artillery bombarded the cultivators

The seven days of class were all about the Star Dou Yin Killing Formation.

The quasi-third-level formation is extremely difficult and can only be polished little by little. Most students can understand most of it before graduating from undergraduate degree. It would be great if they have the ability to serve in second- and third-line troops.

The rest requires continuous learning in the long life of a cultivator, and not rushing for a while.

After school,

Jiang Ding felt a little excited for a moment, so he ran to the library and wanted to choose an aerial fighter of his choice. When he saved enough money, he could entrust the Xianmen Battleship Construction Factory to design and build it.

"Sower-12?"

Jiang Ding clicked on a fighter plane with a fat fish belly on the computer. It was more than three times larger than the Jiao-645 displayed by the Soul-Slaying Monarch in class.

"The firepower is fierce. It can carry twenty-seven Hunter series missiles at one time and drown groups of foundation-building monks. It requires at least twice the spiritual consciousness of monks of the same level to control it. It costs 2.07 million low-grade spiritual stones."

A video was also shown.

With the blessing of a quasi-third-level attack formation by air and space fighters, twenty-seven missiles were fired in a salvo, blasting a twenty-two-person team of outside world foundation-building monks into pieces. No shields or defensive weapons could withstand it. The visual effect is strong.

"It's average."

Jiang Ding said to himself.

Twenty-two monks in the early and middle stages of foundation building are extremely dangerous opponents to him now. If they form a formation, if one fails, they will lose their lives.

But when he was promoted to foundation building, it was indeed a bit difficult.

But spending more than two million low-grade spiritual stones to do this is really a lot of money and there is no place to spend it.

"The Phantom series aerial fighter is extremely fast. The spirit engine is overloaded and can maintain a golden elixir level escape speed for at least six minutes. It costs four million low-grade spirit stones..."

"This is okay."

Jiang Ding became a little interested.

"The electromagnetic hunter-slayer series aerial fighter aircraft has a single electromagnetic main gun. After fifteen minutes of charging, it can blast out a golden elixir-level electromagnetic artillery shell. It requires the "Second-order Electromagnetic Induction Wave Method" to be at least a Dacheng level, and the cost is four One million and two hundred thousand low-grade spiritual stones."

"This is good."

"The Ghost Stealth Hunter series provides golden elixir-level concealment and is a good helper for battlefield reconnaissance. It costs 4.82 million low-grade spiritual stones..."

The entire article extolls this merit and then flips it around.

"Equipped with a second-level mid-level flying formation and a second-level low-level attack formation..."

Jiang Ding thought for a while.

"It's not bad, but the flaws are too big."

After looking around, most of the customized fighter planes are of this type. They have golden elixir qualities in some aspects. The price is four to five million low-grade spiritual stones, which can be used to buy two or three low-grade magic weapons.

It's just that Xianmen subsidizes citizens' first fighter jets at cost price.

In terms of cost performance it is completely inappropriate.

So what if a mere foundation-building monk possesses a certain aspect of golden elixir ability? Compared with a real golden elixir monk, it is much inferior, but the cost is the price of two or three golden elixir monks' magic weapons. It is a huge waste.

"But, it's worth it!"

Jiang Ding's eyes lit up.

When it comes to your own safety, as long as you have it, the spiritual stone will be spent. As long as you are alive and your cultivation level is higher, you will come back after all the gold is spent.

Not to mention,

In the future, you can upgrade to Golden Core, build aerial battleships, and the main guns of aerial battleships can also be upgraded or sold, and you can also regain your health again, no matter what, you won't lose money.

“These are good, but they’re not appropriate and not enough.”

Jiang Ding spent several hours reading through most of the information on aerospace fighters, and ideas came to his mind one by one.

"First, the main gun of the air and space fighter needs an electromagnetic gun. It must have a third-level power that can be fired in a few seconds after charging. I can solve the second-level issues myself after I build the foundation."

"It is best if the main gun is detachable, telescopic, and placed between the eyebrows."

Although without the third-level killing formation bonus in the air and space fighter, the power will be reduced a lot, but it is still a great killing weapon, which greatly guarantees your sense of security.

"Second, the stealth ability must be at the third level, and preferably at the top level of the third level. The stealth coating of Kongming Crystal Copper can achieve this effect without increasing the load... It just needs to be there, and the consumption is It’s huge.”

"The third one is speed. The speed must reach the third level. Only if you can escape with your life can you have a future."

"Haha, we thought it was quite beautiful."

After counting them one by one, Jiang Ding himself laughed first.

I wrote down these requirements, found a store online, and asked the Tier 3 battleship designers who were available.

Very expensive.

Fifteen minutes, one thousand spirit stones, this is almost the amount of savings that several ordinary foundation-building monks have in a year.

It is almost comparable to the appearance fee of a Golden Elixir monk.

Maybe there is a Golden elixir cultivator opposite.

"The industrial level of Xianmen Xiandao can meet the requirements of customers."

This third-tier battleship designer was extremely professional. He did not laugh at Jiang Ding's imagination and answered the questions with his own knowledge.

"The cost of such a super-standard air and space fighter is unbearable for most Jindan monks. There are also many precious materials that may not be available on the market, and there may be a substantial premium."

"It is estimated that the precious materials needed are three tons of third-order electromagnetic spiritual gold as the base material of the main gun. This fairy gate can be artificially synthesized and the cost is relatively low. Seven million low-grade spiritual stones should be enough."

"Kongming crystal copper coating, at least 400 kilograms, 12 million low-grade spiritual stones. There is a price but no market. Most transactions only accept the same third-level spiritual gold."

"Third-grade high-grade Lingzi aerial fighter engine, this one is nine million."

"The formation design, formation inscription, and fighter refining of the third-level air and space fighter aircraft. This extremely special model does not have a production line. It must open a new one. The cost cannot be diluted. The total cost is 10 million."

"All in all..."

"Thirty-eight million low-grade spiritual stones!"

“It’s higher than the cost of many aerial battleships!”

The voice of the Tier 3 battleship designer was louder and sharper.

"..."

Jiang Ding had a big mouth, and he was also severely shocked.

"No value for money, a huge waste."

The voice on the other side paused.

"If the guest is not the only legitimate son of the elderly Nascent Soul Lord, and the house is full of spiritual stones, like garbage, with too much space to spend, it is best not to do this."

"Understood."

Jiang Ding nodded, agreeing with the other person's judgment.

After leaving the library, he went to the cafeteria and ate enough spiritual food to last for half a month. Jiang Ding returned to the cliff edge of the dormitory, facing the sea of ​​clouds, and sat cross-legged.

call out!

The Taiqing Flying Sword flew out from the center of the eyebrow, landed on the cliff and turned into a small tree. The branches, leaves and trunk spread out, three meters, four meters... seventeen meters!

The original small tree is no longer there.

It is a large tree that is as thick as an adult's waist, more than seventeen meters high, with dense branches and leaves, and a shade of more than thirty meters wide. It is made of blue metal, shining in the sun, and its aura is extremely bright.

The metal branches trembled, absorbing the aura of heaven and earth and the essence of the sun within a kilometer radius, and a blurry blue sun shadow appeared between the shades of the trees.

Within ten meters of the tree roots, the cliff that had long turned into colored glaze melted again, forming a deep pool of magma.

From time to time, branches hang down and fall on the shoulders of the young man in green. The filtered, pure and gentle spiritual energy pours into it, greatly accelerating his cultivation speed.

"It is expected that in two years, without any pills, you can reach the eighth level of Qi training."

Jiang Ding closed his eyes and practiced for a while, then opened his eyes.

It doesn't seem too fast, but there are no bottlenecks along the way, including the breakthrough to the foundation building realm.

Compared to other people, it takes decades for one card to pass, and it is absolutely unmatched. It is worthy of the name of a top-level skill.

"The first-order top-quality spiritual veins are not enough...it can be speeded up."

Jiang Ding's figure disappeared.
