However, they are also people who have been trained by Nan Tiancheng and Xi Liuyan, and the previous three-level screening has also given them a certain psychological preparation, plus they are not afraid of heights, so they immediately made adjustments. Gradually, the body stabilized.

"It seems that the first step was a success! South Tiancheng! Let them rise, up to one hundred and fifty meters! Liu Ye ordered.

Nan Tiancheng's order was immediately implemented, and at a height of one hundred and fifty meters, except for Liu Ye, the others could no longer see clearly.

Liu Ye's sharp eyes clearly saw that the five knights on the back of the eagle bat were obviously showing signs of instability, but they could still hold on to their appearance.

"Keep rising, I'm going to see where their limits are!" Liu Ye said coldly.

The height was further increased, and gradually only five small black dots could be seen in everyone's eyes.

As the height increased, the strength of these five knights also showed. The highest is currently at 550m, second at 500m, third at 482m, fourth at 470m, and fifth at 450m.

Seeing their pale faces and slightly trembling bodies, it was obvious that they had reached their limit, and Liu Ye gave an order to let them return to the ground.

The five were sweating profusely, their faces were pale, and their bodies were trembling. Because the altitude is too high, there is a lack of oxygen, and as soon as it falls inside, it immediately exhales heavily, as if it has been holding its breath for 30 minutes.

"Remember their average height - 490 meters, this is their current strength stability line, which means that you have to raise everyone's height to this average height first!" Liu Ye turned around and said to Xi Liuyan and them.

"Second, we want to let them be able to do anything at an altitude of 490 meters, instead of just a child killing them like now!"

"The third is to further improve their limits, the height of 490 meters is definitely not enough, at least to the height of 1000 meters to really form a lethality!"

"I repeat, it's not just about reaching an altitude of 1,000 meters, what I'm asking for is that they can do exactly the same action in the sky as they do on the ground!"

"When they do this, they can become official knights, otherwise they will always have to hang the prepared name!"

"Remember, you only have one month! In a month's time, I want to see the results and decide whether to continue building the Eagle Bat Army! ”

Liu Ye emphasized again and again.

Hearing Liu Ye's request, the faces of the five reserve knights immediately changed, and they were unbearable just after rising to a height of five hundred meters, and the problem of thin air alone was not easy to solve. If you rise to a height of 1,000 meters, you have to make a series of high-consumption actions, which will really suffocate people.

Neng Xuan Qi can solve some of the breathing problems, but you can't always use Neng Xuan Qi for internal breathing, you must know that internal breathing can only be carried out based on the consumption of Energy Xuan Qi.

"Look at you bear-looking! Still a man? Is this little difficulty stumping you? Is there still a little backbone? Xi Liuyan pointed to the five knights who were like dirt and 'colored' and scolded.

However, scolding and scolding, looking at the expressions of Xi Liuyan and Nan Tiancheng, they were also quite embarrassed, and Liu Ye's requirements were a little too high.

If they don't meet the requirements, they will also have regrets. At the beginning, Liu Ye promised them that if the establishment could be completed, Xi Liuyan and Nan Tiancheng could become the leaders of the Eagle Bat Regiment.

The two of them have long been a little jealous of the military power in the hands of Bin Lang, and now they have this opportunity to master a more powerful force, how not to let them fight for it.

However, it is obvious that this so-called most powerful army is really not so easy to master, and just looking at the current requirements will know the difficulty in the future.

There was no way, the two of them could only '' to the death

However, Liu Ye didn't care about this, he turned around and left after saying the above requirements. As the lord of a city, he has too many things to do, and at present, just issuing orders to clarify the requirements makes him unable to get out of his body, where is there time to take care of other things.

And just now, the mastermind was calling out to him again.

"Listening to the tone of the mastermind, it seems that there is something good again!" Liu Ye thought to himself.

……

"How is Liu Ye? Do you like the abilities of the eagle bat? As soon as he entered the main brain, the main brain asked excitedly.

As the creator of the eagle bat, the mastermind certainly wants to know how well it performs.

"Didn't you see it all? Do you need to ask me? Liu Ye smiled, but the smile in his eyes was very rare.

"Huh! I saw it, but what I want to hear is what you think! The mastermind said meaningfully.

Liu Ye sighed and said: "There is no problem with the eagle bat, but there is a big problem with the personnel of '' it!" ”

"You agree with me, now you should understand why you don't want to blindly expand the number!" The Mastermind laughed.

Liu Ye nodded: "Yes!" Instead of blindly producing power that you can't even control, it's better to hold the power you can use firmly in your hands! ”

"If only you understood! During this time, the rapid development of the capital city and Haiwei City has made you a little impatient! The mastermind said earnestly.

"Not bad! You're right! I'm in a bit of a '' hurry! But...... Mastermind, is there something wrong with you calling me all of a sudden? Liu Ye nodded, what the mastermind said just now was reasonable, and at the same time, he was also curious why the mastermind suddenly called him, there are not many such things. 、

The mastermind let out a hey laugh and said, "Do you remember the chip you just gave me?" ”

"Of course I do! It's only been a few days, didn't I give it to you? Liu Ye naturally knew that the treasure that he couldn't open for the time being.

"I've got good news for you! I've found something inside the chip that you can use for the time being! The mastermind said mysteriously.

"What can I use?" Liu Ye was stunned for a moment, and then asked in surprise: "What is it?" Frigate? Submarine? Or is it some other warship? ”

"Damn!" Liu Ye's question choked the main brain at once, and it shouted angrily: "You think I'm an immortal, are these things that you can use at the moment?" ”

"Neither, what's that?" Liu Ye asked.

"I found a method for making a simple warship in the chip, maybe you can use it for reference!" The mastermind continued.

"Improvised warships? What is that? Liu Ye was a little puzzled, "Didn't you just say that you can't use the warship?" Why do you say it's okay now? ”

"The warship I'm talking about is completely different from the warship you think, this kind of warship is an unmanned warship that was used for suicide attacks in the past, I think if it cancels its suicide attack, maybe it can be reluctantly used combat ships?" Mastermind explained.

"Suicide ships?" Liu Ye remembered the kind of warship used to be used as a giant torpedo in the past, and the characteristics of this kind of warship were obvious, fast, narrow, and simple.

"That's too much trouble! See for yourself! After the mastermind finished speaking, he 'made' two pictures in front of Liu Ye.

The first picture is of a boat not much larger than a speedboat, wrapped in iron sheets, and the whole is streamlined, like a flying shuttle. There are no weapons other than a rudimentary machine gun at the front, and it seems that this is what the mastermind calls a suicide ship.

Another picture shows an enlarged version of this suicide ship, with a hull twice as large and a frame made of steel and wood and stone for the rest of the frame. On the edge is a large sail sewn from animal skins, fluttering in the wind like a flag.

"The first picture, as you should understand, is a suicide ship! Its engine is simple, and it can produce 'color' in straight line acceleration, but it is weak in cornering. This is also because of its use, which is simplified as much as possible, and I think that at the level of a metropolis, it should be barely able to make it after a period of research! ”

"The second painting is a prototype hull that I developed on the basis of this suicide warship, because the metallurgical productivity of the capital is not high now, so I used wood and stone for the non-critical parts, and the animal skin sail can also provide power when necessary, saving energy!" Mastermind introduced.

"The second type of warship, which we can build at the moment?" Liu Ye was still a little hard to believe.

"It should work! The key technology of a warship is the engine, and if you let the terrier lead the people to concentrate on it for a while, I think they will be able to study it. As for the aerodynamics of the hull, I just refer to the information of the suicide warship, and it has been expanded twice, so it is not an illegal procedure! As for weapons! I'd like to get the boat running first! The mastermind replied.

Liu Ye still asked with some unease: "Is it strong enough to use wood and stone?" You have to understand the horror of mutant creatures on the sea! ”

"You don't have to worry about this, I don't just lay the wood so roughly, but the outer layer is made of stone, and the inner layer is made of wood, a total of four layers. Although the process is more complicated, the need for steel is much reduced, and both waterproofness and sturdiness are not much worse than steel hulls! It's even better than steel in terms of service life! As if peddling a product, the mastermind patted his chest and assured.

"Then let's build one first, if it's as good as you say! I don't mind mass production! After all, this is also shipbuilding, and with the first step, it will slowly develop in the future! Liu Ye groaned for a while and said.

"Good! I immediately sorted out the relevant information, hello for the allocation of resources! "The mastermind said excitedly, as if the manufacturer had found a buyer for its product.

"Yes! Let's say it first! Liu Ye nodded and left.
