"Shimin, mother, let me say this, not for anything else, but for our family, so that we can all be happy! And Feng'er will help you with things that you all the civil and military ministers of the court can't solve, you give Feng'er Isn't it right to give some rewards? There is no hard work for nothing in the world, and Feng'er is still your child, how can you be so stingy with your own child?"

"Oh mother, you can say I'm stingy, but you say Feng'er is poor? Does he have no money? That's impossible!"

Li Shimin's mood at the moment can be described as very helpless.

Because Empress Dou didn't know that Li Chengfeng went to Suzhou and cheated Tubo and Turks of 430,000 gold.

Coupled with the more than 200,000 gold he owns, Li Chengfeng's current net worth can be said to have reached more than 600,000 gold.

It would not be an exaggeration to say that he is the number one person with the strongest liquidity in Datang.

Although 600,000 gold is nothing to the national treasury, it is not too much to some super big families of the Tang Dynasty.

But don't forget that there are at least tens of thousands of people to support a big family, and all the assets in their hands are counted as jewelry, farmland, houses, restaurants and the like.

So the working capital in their hands may not even be 300,000 gold.

But Li Chengfeng has more than 600,000 gold in his hands, real gold!

To be honest, Li Shimin himself was a little envious!

But Empress Dou spoke up in person, and Li Shimin was too embarrassed to say that she would not pay Li Chengfeng.

Let's not talk about how much money Li Chengfeng has, even if Li Chengfeng helps Datang, as the emperor, he should pay Li Chengfeng.

So Li Shimin nodded slightly, and said: "Well, if Feng'er can really help me with that matter, then I will reward Feng'er with 10,000 gold, is that okay?"

"Ok, no problem!"

Li Chengfeng readily agreed to Li Shimin's condition.

…

In the afternoon, after lunch, Li Chengfeng returned to the Zhenwang Mansion.

While Li Shimin went to deal with the government affairs, Li Lizhi and Wu Xu kept playing beside Li Chengfeng.

Li Chengfeng was still thinking, why did today's soil-quality fraudulent bomb explode so slowly?

There must be something wrong with one of the links!

"The iron sheet is too thick, so the explosion effect is delayed. This is a problem! So we need to add more saltpeter ash!"

"Put too much igniting gravel, which will cause the heat transfer to be too slow, or the gravel will not be able to cause sparks and ignite the saltpeter ash! So you can put a little less igniting gravel in!"

"First add loess, then saltpeter ash, and finally put a layer of gravel on top!"

Li Chengfeng started to make earthy bombs at the entrance of the hall of the Prince's Mansion.

Li Lizhi and Wu Xu, propping their cheeks like this, silently watched Li Chengfeng make earthy fraudulent bombs!

Li Lizhi asked suddenly: "Brother Feng'er, where did you get the materials for making the bombs?"

Li Chengfeng thought for a while, and said: "It was brought back from Suzhou last time! There is a saltpeter mine there, I got some back!"

"Oh, then, can you teach us how to make a fake bomb?"

Li Lizhi asked again.

Li Chengfeng cast a glance at Li Lizhi, and said: "Why are you making a fake bomb? What do you want to blow up? This thing is so powerful that it will kill people if you are not careful. Moreover, the power of this thing's explosion today, I think you all know it." See it! Even a rockery can be blown down, let alone our human flesh and blood!"

"Well, actually, I just want to try it, if I can make it!"

"Okay, I'll let you try it later, but no matter whether the production is successful or not, you can't take the fake bomb home, otherwise if the fake bomb explodes suddenly, it may hurt the lives of innocent people!"

"Okay Brother Feng'er, we know!"

Li Lizhi and Wu Xu looked at each other and laughed happily.

Li Chengfeng continued: "However, I'd better try the effect of my newly developed fraud bomb first. If it still takes a long time to explode, then this fraud bomb still needs to be improved!"

"Uh-huh!"

Just do it.

Soon, Li Chengfeng walked out of the Prince Zhen's Mansion holding the soiled bomb in his hand.

Li Lizhi and Wu Xu followed behind Li Chengfeng.

They are looking forward to how powerful this soil-based fraudulent bomb is.

When Li Chengfeng came to a piece of grass, Li Chengfeng pulled off the button and threw it directly towards a big tree on the left.

"3, 2, 1..."

"fry…"

"Boom..."

A huge explosion sounded, and the three of Li Chengfeng only felt the ground under their feet tremble.

At this moment, Li Chengfeng was naturally extremely happy in his heart.

Because the soil-based fraud bomb he developed finally succeeded.

The first time the fraudulent bomb was made, it is very likely that there was too little saltpeter ash. This time Li Chengfeng increased the amount of saltpeter ash and reduced the amount of ignited gravel. The clock exploded.

Excluding the three seconds for pulling the button and throwing the fraudulent bomb, the detonation time of this fraudulent bomb is about six seconds.

It can be regarded as a qualified result~lightnovelpub.net~ Li Chengfeng wiped the sweat from his forehead, his face became uncontrollably excited.

If this fraudulent medicine is brought to the battlefield, it can definitely bring about a devastating blow.

As long as there are enough fraudulent bombs, who cares about the 200,000 troops of Tubo and Turks?

It's fine to blow all the way to such a lair.

…

Li Chengfeng hurriedly ran to the place where the bomb exploded, and saw a huge hole suddenly appeared on the ground. The roots under the big tree were broken by Li Chengfeng, and the whole tree was torn apart by the bomb.

"Brother Feng'er, the power of this fraudulent bomb is so powerful!"

Li Lizhi stared wide-eyed, looking at the big hole in front of her that was blown out by a fraudulent bomb.

Li Chengfeng clapped his little hands and said, "Yes, this is the difference between hot weapons and cold weapons!"

"What is a hot weapon? What is a cold weapon?" Li Li asked.

Li Chengfeng replied, "Cold weapons are weapons such as knives, guns and sticks, while hot weapons are weapons such as fake bullets. So, in front of hot weapons, a three-year-old child can also use fake bullets." Killing a peerless master, this is the power that technology brings to mankind!"

At this moment, Li Chengfeng was also sighing in his heart.

I just created a fraudulent bomb, and it was almost enough to change the battle situation of the entire Tang Dynasty.

In the 21st century, all kinds of bombs, missiles, guns, and even nuclear weapons, the kind of fraudulent bombs are the most deadly.

Just put one down and slaughter the city directly.

So Li Chengfeng is still thinking, should he bring the fraudulent bombs to the battlefield? ?
