Of course, Leng Feng knew what a heaven-level thunderbolt was, and even knew what the power-of-heaven-level apex looked like.

But...... How to make it?

The only three remaining grenades of the cold front have TNT, which is much stronger than black powder. But Leng Feng only knew that TNT was called trinitrotoluene, which was benzene with one CH3 and three NO2s, but he had not learned how to make it, and there was no need to learn it.

The black market of the United States, all kinds of non-strategic weapons can be obtained, as long as you have money!

As for the nuclear bomb and hydrogen bomb that shocked the world, Leng Feng only knew that he applied the principle of atomic fusion and fission to release energy. One uses uranium or plutonium, and the other uses deuterium or tritium, but I still don't know how to get it.

Uranium with iron next to it, is it metal? If tritium carries gas, does it have to be a gas?

In this era when knives, guns, axes and axes are the basic weapons, and the eight bull crossbows are already strategic weapons, if nuclear bombs appear, then its deterrent power will be unparalleled.

However, the advent of nuclear bombs may also trigger a worldwide counterattack.

However, how can we ensure that Datang stands proudly on this land without a nuclear bomb.

But......

Leng Feng didn't notice that he had left the Thunderbolt Division at all, and the thoughts in his head were like a bunch of tangled messes that couldn't be solved.

Zhang Zhongqing followed behind Leng Feng, he didn't expect that he would make Leng Feng like this just by mentioning the "Heaven-level Thunder". can only follow behind Leng Feng and beware of something happening to him.

From early morning to dusk, Leng Feng had been walking back and forth between the Thunder Division and the Tianxia Academy with his chin in one hand, and the soles of his shoes were worn out without realizing it.

Up to now, Leng Feng had followed more than a dozen people sideways.

Liu Shuwen came over after getting the news, Li Chengqian's brother came over after getting the news, and Li Erniu and Ergouzi came to guard after getting the news.

Yao Silian and Han Chongwen lived in their new house, and after seeing Leng Feng's behavior, they severely stopped Zhang Zhongqing's plan to wake up Leng Feng.

In the end, even Li Shimin came in a hurry on a horse wearing a dragon robe.

"What's going on?"

Li Shimin jumped off without waiting for the horse to stop, was mixed by the dragon robe, and almost fell to the ground.

The monkey that followed behind Li Shimin, or the dragon shadow, supported Li Shimin in time.

Zhang Zhongqing didn't even give a salute, and replied: "When he came in the morning to urge us to step up the production of thunder arrows, I asked him what was going on with the heaven-level thunder, and he began to ponder, and finally it became like this. ”

"Heaven-level thunder?"

Li Shimin saw that Leng Feng was about to hit the tree, and just wanted to stop it, but was stopped by Yao Silian.

"Your Majesty must not disturb him, now the landlord is in deep thought about something, if he has figured it out, or knows that he can't figure it out, he can come to his senses. If you are awakened by outsiders, it is easy to be very sad. ”

Li Shimin clapped his hands: "Isn't this the same as sleepwalking?" ”

Han Chongwen nodded on the side and said, "In the early years, this happened to the old man when he read "Xiaoyaozi", and he was seriously ill for a month after being woken up by my senior brother. ”

While everyone was talking, Leng Feng had already walked to the edge of the tree, and when the hair on his forehead touched the tree, he unconsciously avoided the tree and continued to walk in a different direction.

Liu Shuwen saw that there were already blood stains on Leng Feng's shoe prints, and hurriedly said to Han Chongwen: "Master, there is no way to go on like this, we can't just watch it like this!" Do you know how? ”

Han Chongwen thought for a while, and asked the emperor: "Your Majesty, the old man dares to ask what the heaven-level thunder is?" ”

Li Shimin glanced at Zhang Zhongqing, Zhang Zhongqing understood, and sent everyone except Li Shimin, Long Ying, and Han Chongwen to follow Leng Feng.

Only then did Li Shimin speak: "It is a weapon applied to the army, and the power of using it once can completely turn a village into ashes at the very least." ”

Han Chongwen's arched hand trembled, and he almost exclaimed, if a weapon really has such power, then it should not be called thunder, but should be called heavenly punishment.

Zhang Zhongqing continued: "This kind of weapon, Leng Gongzi must have seen it, otherwise it is impossible to know its power. Maybe...... Leng Gongzi knew that this thing existed, but he couldn't create it himself, so he fell into contemplation. ”

Han Chongwen stroked his beard and thought for a long time before he said: "It's nothing more than the words 'so ambitious', the old man has a way!" ”

Leng Feng was reminiscing about World War II at this time, and how did Oppenheimer develop the nuclear bomb during that time period?

In his contemplation, he always felt that there was a white shadow shaking in front of him, and there seemed to be words on the white shadow? So he couldn't help but try to see it clearly.

The second dog, who was holding a blank paper in front of Leng Feng and retreating with Leng Feng, saw that Leng Feng had stopped, so he stopped.

Leng Feng looked at it for a long time before he could see what the words on the white shadow were.

"Down-to-earth"

These four words were written thick and low at the bottom, but the top was sharp and sharp, nondescript.

"Down-to-earth?"

Leng Feng couldn't help but look at the font again, the bottom of the three parts of "Moon", "Go", and "Knock" are all on a horizontal line, and the bottom is thick, and it seems that it will not fall when taken out separately on the ground.

Down-to-earth places can stand!

In 1860, industry began, and the advent of such a thing as the steam engine completely opened the door to "technology". By the time the nuclear bomb exploded in 1945, it was only 85 years.

In other words, the appearance of nuclear bombs was created "out of nothing" in the past eighty-five years!

And what is it that appeared in favor of a nuclear bomb?

Knowledge!

The knowledge left by countless predecessors is like a cornerstone that supports the scientific system, and in a hundred years of life, a person does fantasy, even if he thinks about it in his head, it will be useless, and he still can't think of uranium 123 or 345, plutonium 567 or 789.

What he can do now is to start the industrial revolution of Datang, be down-to-earth, and let knowledge enter the minds of countless Datang people to precipitate and sublimate.

Someday, the nuclear bomb will come out.

One day, Datang's knowledge will be ahead of the world and will always occupy the throne of the overlord!

Leng Feng, who had figured it out, felt the tingling pain in the soles of his feet and the exhaustion all over his body, and his body staggered, and he almost fell to the ground.

Han Chongwen and Yao Silian, who had been waiting behind Leng Feng for a long time, supported Leng Feng alone.

Leng Feng couldn't help but gasp again and again: "What's wrong with me?" ”

Li Shimin leaned over to Leng Feng and squatted down and said, "You have been thinking about the problem today, don't think so much, quickly close your eyes and rest." ”

Saying that, Leng Feng also felt the heaviness of his eyelids, listening to Li Shimin's voice was like listening to a lullaby, and his vision was blurred and fell into a deep sleep.

Li Shimin saw that Leng Feng was already asleep, so he sighed, and ordered Ergouzi and Li Erniu to carry Leng Feng back on a stretcher, and instructed the guards who had arrived late to pass the imperial doctor.

After Leng Feng was carried away, Li Shimin glanced at Han Chongwen and coughed.

Han Chongwen covered his lips and coughed, saying that he would keep his mouth shut and never reveal it.
