Unlike other places, the area of ​​Mohist school is not simply dormitory and teaching areas, but is more subdivided into many different areas.

As Zhao Kuo walked along the way, he saw different brands such as "physical experimental zone", "chemical experimental zone", and "theoretical discussion zone", which made him feel like he was returning to college in later generations.

In a place with the sign "Extremely Dangerous Area" hanging, Kure really pushed open the door.

Unexpectedly, after opening the door, it was not a house, but a large open space comparable to a playground.

There are many small compartments at the edge of the open space. Most of the doors of the compartments are closed and it is hard to see what is inside.

In the center of the open space, a huge rock that was as tall as a man was placed there.

Kuchi coughed and said, "Junhou, the gunpowder recipe you gave before is actually very powerful. You can't even blow a stone, which really makes us a little worried."

Zhao Kuo: "...Ahem, that's right, you've improved it now, right?"

Zhao Kuo is actually a bit innocent. After all, he didn’t study gunpowder in his previous life, and he was a major in explosives. The formula of gunpowder was also seen from the vast number of online novels. What can I do?

Fu Zhen nodded and said, "Yes, after research, we found that the charcoal in the gunpowder formula needs to be selected from pine wood, and it also needs to be fired at high temperatures, and the temperature must be strictly controlled.

At the same time, the choice of sulfur must be very cautious. The quality of sulfur in Handan has never been satisfactory. However, we later found that sulfur produced in Dai County..." The endless introduction made Zhao Kuo a little overwhelmed, but he still suppressed his temper and listened.

As professionals, they always have to respect their professional knowledge.

A little far behind, Li Si and Han Fei stood there with a strange expression.

Li Si couldn't help but whisper: "These people from the Mo family... are all like this, um, do you have personality?"

Han Fei smiled bitterly and said, "I'm not sure."

Li Si sighed lightly: "I don't know why you asked us to come here."

Li Si felt that coming here today was a waste of time, and it would be better to deal with more official duties.

Finally, Ku Zhen finished the introduction of the long speech, touched his head, and smiled embarrassedly: "No one has spoken for a long time. I have said a little more, so I laughed at you."

Zhao Kuo laughed and patted his belly and shoulder: "It's okay.

Now, show me your achievements.”

Kuchi Zhen nodded and pointed to the huge stone not far away: "Have you seen that stone?"

That is, the pine stone used to build Handan City Wall, which is very hard and is difficult to damage even if the stone thrower is used.

The previous explosions show that our gunpowder explosion power is not strong enough, and the amount required to blow up such a large boulder is too amazing, so there is no practical significance in that way."

Although the explanation of the lumbar really is a bit stupid, Zhao Kuo still understands it.

To put it bluntly, the power of black gunpowder is not enough, so it needs to be collected.

In terms of blowing up the city wall, if the amount of blowing up the city wall in Handan requires one ton, Zhao Kuo might as well dig a tunnel directly into the city wall to save trouble.

Zhao Kuo said: "So how much power has increased now?"

Fu Zhen said: "At least three times.

OK, please take a look.”

Hu Zhen held the torch and walked towards the boulder, then lit the lead and ran back.

Zhao Kuo's face suddenly became solemn, and he said in a deep voice: "Everyone is looking for cover to hide and cover his ears."

Although Xu Li, Li Si and Han Fei didn't know why, they still hid with Zhao Kuo.

"boom!"

A violent explosion suddenly sounded, a wave of air came to my face, and various gravels fell from the sky, and smoke and dust filled with it for a moment.

After a while, Zhao Kuo stood up and looked at the place where the huge rock was just now.

There are no boulders, only a big pit.

He said happily: "Did you see it?"

Now that the power has increased, our gunpowder has fully possessed the ability to blow through the city walls of Handan!”

Zhao Kuo calmed down for a long time, showed a big smile, and patted his belly hard on his shoulder: "Very good, very good, you did a good job in this matter!"

Not far away, Xu Li, Li Si and Han Fei were already stunned.

Li Si murmured: "What did I see just now?"

Xu Li also murmured: "How come such a huge rock is gone if it is gone?"

Han Fei's stutter seemed to be even worse: "God, miracle!"

There is no doubt that this gunpowder explosion shocked the three of them.

Zhao Kuo, who happened to hear the words of the three people, couldn't help laughing: "You are wrong. This is not a miracle, this is... science!"

Gunpowder has official practical significance, and of course it is a huge improvement for Zhao Kuo.

The city walls in Handan can be exploded, so Daliang, Linzi, Xianyang are naturally no problem! In fact, this is also the light of this era that belongs to the "ancient period in ancient times". If it goes forward for hundreds or thousands of years, the quality of the construction of the Chinese city in the Song and Ming dynasties will be improved to the next level, and the city wall can only be exploded with real explosives and shells.

The only regret is that... Zhao Kuo put away his smile and reminded the four confidants present: "This matter must not be mentioned, do you understand?"

The four of them nodded at the same time. No one was fool, so of course they still understood this kind of confidentiality.

Li Si couldn't help but feel excited and said, "June, when can we apply this kind of gunpowder to war?"

Zhao Kuo was silent for a while and said, "At least it will take until this marquis seizes power."

Yes, although he had such a big killer weapon, Zhao Kuo still couldn't take it out immediately.

This is an incomparable trump card, but if the empress dowager knows, the empress dowager will definitely kill Zhao Kuo without hesitation.

Because with gunpowder, the Empress Dowager and Zhao State did not need famous generals like Zhao Kuo who would win every battle! Li Si and Han Fei were both smart people, and they immediately understood what Zhao Kuo meant, and they couldn't help but feel a little regretful: "This, have we invested so many resources, but in the end we can't use it?"

"Who said it cannot be applied?"

Zhao Kuo laughed: "I will tell you the truth. I don't plan to use this weapon on Chinese people."

Can't Zhao Kuo's military ability and commander level be achieved by conquering the six countries and unifying the world?

The reason why we have worked so hard to produce this powerful version of gunpowder for a large amount of resources is to expand our territory in the future.

There are too many places in the Western Regions, grasslands, southern barbarians, Qinghai-Tibet Plateau, and even Central Asia, West Asia, Egypt, and Eastern Europe.

To conquer a territory, the most difficult thing is of course to attack the city.

The siege of cities one by one is too waste of time! The emergence of this powerful version of gunpowder is the best solution to this difficulty.

Such a powerful gunpowder has been developed now. After a few years, Zhao Kuo unified the world and officially launched another area of ​​the earth. How powerful should the gunpowder be at that time?
