The class lasted seven days, and all of them were talking about the Star Fighting Yin Array.

The quasi-third-order formation is extremely difficult, and it can only be ground little by little, and most students can have most of the understanding before graduating from the bachelor's degree, and it is good to have the ability to serve in the second- and third-line troops.

For the rest, it is necessary to keep learning in the long life of an immortal cultivator, and there is no rush for a while.

After school,

Jiang Ding was a little excited for a while, and ran to the library, wanting to choose a favorite aerospace fighter, and when he had 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, which was more than three times larger than the Jiao-645 displayed by the Soul Killing True Monarch in the classroom.

"The firepower is fierce, it can carry twenty-seven hunter series missiles at one time, and it can drown the groups of foundation building monks, and it requires at least twice the divine sense of the monks of the same rank to control, and it costs two million and seven thousand spirit stones."

A footage is also shown.

With the blessing of the quasi-third-order attack formation of the aerospace fighters, twenty-seven missiles were fired in a salvo, blasting a twenty-two team of out-of-bounds foundation building monks into pieces, and no shields and defensive magic weapons could be carried, and the visual effect was very strong.

"Average."

Jiang Ding muttered to himself.

Twenty-two early and middle stage monks of the foundation building are extremely dangerous opponents for him now, forming a formation, and if one of them is not good, he will lose his life.

But when he was promoted to build the foundation, there were indeed some difficulties.

It can cost more than two million lower grade spirit stones to do this, and there is really so much money that there is no place to spend it.

"The Phantom series of aerospace fighters is extremely fast, and the Lingzi engine is overloaded, which can maintain a Jindan-level escape speed for at least six minutes, and cost four million lower grade spirit stones......"

"It's okay."

Jiang Ding was a little interested.

"The electromagnetic hunter series of aerospace fighters, a single seedling and an electromagnetic main cannon, can blast out a Jindan-level electromagnetic cannonball after fifteen minutes of energy storage, and it requires the "Second-Order Electromagnetic Induction Fluctuation Method" to at least complete the realm, costing 4.2 million lower grade spirit stones."

"That's good."

"Ghost stealth hunter series, providing Jindan-level concealment, a good helper for battlefield reconnaissance, costing 4.82 million spirit stones......"

The whole article boasts about this advantage, and then turns around.

"Equipped with a second-order mid-grade flight formation, a second-order low-grade attack formation......"

Jiang Ding thought for a moment.

"It's not bad, but the flaw is too big."

After turning around, most of the customized fighters are of this type, and they have the characteristics of Jindan in some aspects, and the price is four million to five million low-grade spirit stones, and they can buy two or three low-grade magic weapons.

It's just that Xianmen has a subsidy for the first fighter of the citizens, the cost price.

In terms of price-performance ratio, it is completely inappropriate.

What about a mere foundation-building monk, even if he has a certain aspect of Jindan ability, it is much worse than a real Jindan monk, but the cost is the price of two or three Jindan monks' magic weapons, which is a big waste.

"But it's worth it!"

Jiang Ding's eyes lit up.

When it comes to their own safety, as long as there is, the spirit stone will be spent, as long as you live, your cultivation will be higher, and your daughter will come back when you are gone.

let alone

In the future, if you are promoted to Jindan and build an aerospace battleship, the main guns of the aerospace fighters can also be upgraded, or sold, and they can also recover blood again, and you will not lose anything.

"It's good, but it's not quite right, and it's not enough."

Jiang Ding spent several hours reading the information of most of the air and space fighters, and one thought after another came to mind.

"The first one, the main gun of the aerospace fighter needs an electromagnetic cannon, it must have, the third-order power, the kind that can be fired in a few seconds with energy storage, and I can solve the things in the second order myself after I build the foundation."

"The main gun should preferably be detachable, telescopic in size, and placed on the center of the eyebrows."

Although the power will be reduced a lot without the third-order killing array bonus in the aerospace fighter, it is still a big killing weapon, which greatly guarantees its sense of security.

"Second, the concealment ability must have a third-order, and it is best to be at the top level of the third-order, the stealth coating of the Void Crystal Copper can achieve this effect without adding much weight...... It is necessary to have, and the consumption is very large. ”

"The third, speed, the speed must reach the third-order level, and only if you escape your life can you have a future."

"Haha, we think it's pretty beautiful."

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

Write down these requirements, find a shop on the Internet, and ask the designer of the third-order battleship who is available for it.

Very expensive.

Fifteen minutes, a thousand spirit stones, and the savings of several ordinary foundation building monks for a year are almost this amount.

It's almost comparable to the appearance fee of Brother Jindan.

Maybe it's the Jindan monk on the other side.

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

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

"The cost of such an over-specification aerospace fighter is also unbearable for most Jindan monks, and there are many precious materials, which may not be available on the market, and there may be a large premium."

"It is estimated that the precious materials needed, the three-ton third-order electromagnetic spirit gold is used as the base material of the main cannon, this immortal gate can be synthesized artificially, the cost is relatively low, and seven million lower-grade spirit stones should be enough."

"Empty Immortal Crystal Copper Coating, at least four hundred kilograms, 12 million lower-grade spirit stones, there is no market, most transactions only accept transactions with the same third-order spirit gold."

"The third-order high-grade Lingzi Aerospace Fighter engine, this nine million."

"The third-order aerospace fighter formation design, formation inscription, and fighter refining, this extremely special model has no production line, and a new one must be opened, and the cost cannot be diluted, adding up, 10 million."

"Total ......"

"Thirty-eight million lower grade spirit stones!"

"It's higher than the cost of many aerospace warships!"

The third-order battleship designer's voice was raised and sharpened.

“……”

Jiang Ding's mouth was long, and he was also shocked fiercely.

"It's cost-effective, it's a huge waste."

The other side paused in tone.

"If the guest is not the only son-in-law of the old Yuanying Zhenjun, the spirit stones are piled up all over the house, and the garbage is the same, so much that there is no place to spend it, it is best not to do this."

"Understood."

Jiang nodded his head in recognition of the judgment of the other side.

Leaving the library, going to the cafeteria for a walk, and eating 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.

Shout!

The Taiqing Flying Sword flew out of the center of the eyebrows and landed on the cliff to become a small tree, and the branches and leaves and trunks stretched out, three meters, four meters...... Seventeen meters!

The original little tree is long gone.

It is a big tree with a thick waist pole, more than 17 meters high, dense branches and leaves, and a shade width of more than 30 meters.

The metal branches trembled, and the heaven and earth aura and the essence of the Great Sun within a radius of thousands of kilometers were absorbed by it, and a round of vague blue Great Sun phantoms appeared between the shades of the trees.

Within ten meters of the root of the tree, the cliff that had long been turned into glass melted again, forming a deep magma Xiaotan.

From time to time, branches hung down and landed on the shoulders of the young man in Tsing Yi, and the filtered and filtered pure and gentle spiritual power poured into it, greatly speeding up his cultivation speed.

"It is estimated that in two years, without any pills, you will be able to reach the eighth level of Qi training."

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

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

Compared with other people, one card is decades, and the desire to die is definitely an unattainable speed, worthy of the name of the top-level exercises.

"The first-order supreme spiritual vein is not enough...... It can also be speeded up. ”

Jiang Ding's figure disappeared.
