After a few days of explanation, Zhang Wenkai was tired, and he can now deeply understand how hard teachers are, especially those teachers with a heavy sense of responsibility.

However, it is gratifying that he finally focused on explaining the knowledge involved in the electronic products used in the destroyer, and he had an in-depth discussion with these professors about the use of each product.

It will be explained until they are able to design the internal holographic system independently.

And in the detailed explanation, all the drawings of the electric destroyer were sorted out and handed over to the Jiangnan shipyard for analysis and integration.

However, there is still one last problem, that is, to build the destroyer designed by Zhang Wenkai, the aircraft carrier steel will be used.

Geng Changfeng has already reflected this matter, but in the end it has been ruthlessly rejected, and the country simply can't afford to spend so much money to build a new type of destroyer.

Seeing this situation, Zhang Wenkai directly released a bombshell, that is, he provided a special steel with a yield of 1000.

Geng Changfeng, who heard the news, suddenly widened his eyes and was surprised.

At present, the country has just begun to study the -100 special steel of the US Empire, and the yield strength of this special steel is only 690, Zhang Wenkai took out 1000 special steel, how can he not surprise Geng Changfeng.

Surprised, Gui was surprised, but Geng Changfeng immediately calmed down, he knew that Zhang Wenkai would not say the news of special steel without a purpose.

"What's on your mind?"

Looking at Geng Changfeng's cautious appearance, Zhang Wenkai couldn't help laughing, saying that he is not a robber, as for being so nervous!

"This special steel technology is also something I have just researched based on my knowledge of special materials, and I came up with this technology this time in the hope that the country can manufacture two destroyers." Zhang Wenkai knew that he was not doing anything right, but at a critical moment, he also wanted to make a contribution to let the country build two destroyers and promote the national prestige.

Geng Changfeng slowly leaned back in his chair and did not speak.

"I'll give you a solution, that is, tear down the east wall and make up the west wall." Zhang Wenkai continued.

◇dǐng◇diǎn◇小◇語,.※.∧os_(); "What do you mean?" Geng Changfeng frowned.

"That is, the special steel used in the aircraft carriers currently built is used in the construction of destroyers, and the special steel I provide is used in aircraft carriers."

"Bad idea!" This is Geng Changfeng's first feeling, the keel of the second aircraft carrier has been manufactured, and segments are still being built in other places, so no information has been leaked, and the outside world has not found any useful information, and the country only says that it is under construction.

Since it has been built, then it is not possible to replace other materials, how can it be said that it will be replaced, isn't this a joke!

Seeing Geng Changfeng shaking his head, Zhang Wenkai shrugged his shoulders, this is all he can do, since the country is unwilling to spend money, he has nothing to do.

And this technology is not given in vain, how can you give a few money, since you have done this, if the country still does not agree, Zhang Wenkai can only turn around and leave.

"I still want to spend no money, I still want to develop fast, if there is such a good thing in the world, Lao Mei and Lao Maozi will jump to the sky." Zhang Wenkai couldn't help but complain.

"Wait!" Geng Changfeng still kept Zhang Wenkai.

"Can you make some first, let's see." Geng Changfeng asked.

"Whew!" Zhang Wenkai couldn't help but laugh, if he produced it himself, it would not be as simple as providing technology, and then he would have to buy the product.

"It's okay, if you're not afraid of spending money, I'll form a team and start manufacturing, and I can tell you, when the time comes, I'll sell goods."

Zhang Wenkai is not wrong, if special steel can be manufactured, the corresponding production line will be manufactured, if it is not to sell the product, how to make money back from the production line.

Moreover, the production line has a thick plate rolling mill or something, who is stupid to sell the technology, just sell the finished product completely, and the profit is still high.

Zhang Wenkai's words silenced Geng Changfeng again, he knew that what Zhang Wenkai said was very reasonable, and he was powerless to refute it.

Although Geng Changfeng doesn't know how to make an aircraft carrier, he still knows some common sense, just like this kind of special steel with yield strength, welding is a problem, and when the time comes, special steel will not be welded, and it will be in vain, and he is worried because of this problem.

"If you have any questions, my patience is limited." The initiative is in Zhang Wenkai's hands, and he is not in a hurry anyway.

"The problem of welding cannot be solved." In the end, Geng Changfeng still told the truth.

Zhang Wenkai's eyebrows raised: "If welding can't be solved, then you can't pour it throughout." ”

Hearing Zhang Wenkai's words, Geng Changfeng said sarcastically: "Don't talk nonsense here without knowing anything." ”

"Do you know how much such a large mold costs? Besides, it is impossible to produce such a mold. ”

"And no country has produced in this way."

At this time, Zhang Wenkai deeply despised Geng Changfeng, always following the path of others, how can there be a day when he comes out, if he wants to become stronger, he must always do something crazy in the eyes of others, not to mention that there is his own variable in it, what are you worried about.

"I tell you people when you guys will be able to change their minds." Zhang Wenkai felt very speechless.

"Have all the drugs used to develop the brain domain been taken in vain?" He questioned Geng Changfeng.

Zhang Wenkai's repeated questioning, Geng Changfeng's face also became ugly.

"I can make a mold production line or anything, as long as you can afford to buy it, I can build it for you."

"How? This business is not a loss! This time, Zhang Wenkai also got on the bar with Geng Changfeng.

Zhang Wenkai said that the manufacturing method of this mold is also feasible, this method is still provided by Xiao Na, Xiao Na's statement at the time is like this: "Large spaceships use this method, if you weld it piece by piece, the ship will not go far, and it will not work in strength." ”

And Cortana also said that only by using this method can the steel to be poured be mass-produced, and if a large spaceship is welded piece by piece, it will take a year of monkeys.

Zhang Wenkai thinks that what Xiao Na said is also very reasonable, if she can support the invasion of the planet, if she doesn't have strong industrial manufacturing capabilities, it will be over a long time ago.

"Wait a minute, I want to think about it" Geng Changfeng, who listened to Zhang Wenkai's words, fell into deep thought, and at this time he was already excited.

"It's a godsend."

"If you don't accept this, I'm sorry God!"

Geng Changfeng did not hesitate to take out the satellite phone and dialed the first station directly, this matter must be reported to the chief. (To be continued.) )
