I'm a useless prince, so what if I know a little bit of chemistry?

Although Xiang Long was not as smart as Zhang Guangzhi, he was not stupid either. After listening to the conversation between the two, he knew that the thunderous thing just now was a trap for the jar.

Xiang Long felt a little scared when he thought about it. After all, he was the one who put the jar into the pit. If the jar exploded when he was putting it there, he would be really finished.

"My lord, with this thing, we don't have to be afraid of the Huns. Let alone hundreds of thousands, even if there are millions of people, as long as there are enough of this thing, we can still rescue the general." Chu Hu said happily. At this moment, he had no other ideas and just wanted to go to the grassland to rescue people as soon as possible.

"Yes, if there are a lot of these things, the hundreds of thousands of Huns will be like chickens and dogs. How can they resist?" Zhang Guangzhi analyzed it and thought about how much effect this thing called explosives could have.

It can not only be used on the grassland, but also in a series of siege battles. If it is used to blow open the city gate, it will reduce a lot of casualties.

Since ancient times, the battle with the heaviest casualties on the battlefield was siege warfare, which was called minced meat and countless people died in it.

Each siege may require three times or even more troops to capture the city. Sometimes, some strong cities can be defended with only a small number of troops.

If Daliang wants to conquer the world, it must first start a war. In this case, the effect of this explosive can be seen.

Of course, it was not just Zhang Guangzhi who thought of this. Chu Hu and Xiang Long also thought of this. However, none of the three mentioned it because they were not sure whether, if this thing was really taken out, it would allow Lin Fan to move to a higher level or cause Lin Fan to be ostracized by all officials and feared by Emperor Liang.

Everyone knows that Lin Fan's power is too small now, almost too small to be smaller. In this situation, Lin Fan has to be cautious. After all, the water in the court can really drown people.

"My lord, can this explosive be mass-produced?" Zhang Guangzhi looked at Lin Fan and asked.

"Okay, but there are some steps that can only be done by us, and outsiders are not allowed to do it." Lin Fan said.

Maybe others can't remember the proportions, but through repeated experiments, they will be able to figure it out. By then, Lin Fan himself will have no advantage at all.

"In this case, the task of rescuing the general is basically done. Now it depends on how the lord can return to the capital safely." Zhang Guangzhi said.

"Well, I guess someone will come to rob and kill me in that place again." Lin Fan said coldly.

"Then what should we do? Even if the Marquis is fine on the road, it will be a troublesome thing if we are delayed." Xiang Long asked.

"How about we split our forces into two groups?" Lin Fan asked with a smile.

"Divide the troops into two groups?" Chu Hu and Xiang Long were stunned, thinking that Lin Fan was planning to go to the capital by himself. Wouldn't that be courting death?

"My lord, you can't do that!" Xiang Long advised.

"My lord, I, Chu Hu, will protect your safety even at the cost of my life. You must not divide your forces." Chu Hu also advised.

Lin Fan didn't say anything, because the fact that the two of them could say this showed that they were loyal enough, and this was what Lin Fan needed.

Lin Fan did not answer the two people, but looked at Zhang Guangzhi. Although Lin Fan could make directional decisions himself, he still had to rely on his advisers for details. If he did everything himself, Lin Fan would be exhausted.

Zhang Guangzhi lowered his head in thought. He naturally knew what Lin Fan was planning to do, so he began to think about the details of how the plan could be implemented.

First of all, when Lin Fan said about splitting the troops into two groups, he naturally did not mean that Lin Fan would take a group away by himself. What Lin Fan meant was that he would take a few people with him, disguise themselves as another group, and then enter the capital from different directions.

Then Zhang Guangzhi and others returned to Beijing along the original route. After Lin Fan entered Beijing, naturally no one would come to rob and kill him.

This plan is good and can greatly reduce the risk, but the key question is, who will play Lin Fan?

If there was no one who looked like Lin Fan, then those rats hiding in the dark would naturally not be fooled.

"My lord, we need someone to play the role of the lord, but the choice of this person is really difficult for me." Zhang Guangzhi hesitated.

"Playing the role of the Marquis?"

Chu Hu thought about it, and seemed to vaguely understand what Lin Fan wanted to do, so he said: "If I play the role of the Marquis, I definitely don't look like Xiang Shazi. Our body shapes and temperaments are different. Old Taoist Zhang can't play the role either, because you are too short. Brother Shi'an can't play the role either, because he is too tall. Who else can play the role?"

What Zhang Guangzhi thought was what Chu Hu said, but Zhang Guangzhi already had a candidate in mind.

Lin Fan looked at Zhang Guangzhi's expression and knew that Zhang Guangzhi had already come up with a result, so he asked, "Does Taoist Master Zhang have a candidate?"

Zhang Guangzhi smiled and looked around the city.

Chu Hu was puzzled and asked doubtfully: "Master Zhang, you are not asking this guy to play the role of the Marquis, are you?"

Xiang Long glared at Chu Hu and said, "Sir, what you mean is that the person who wants to play the role of the Marquis is in the city, not this city, you fool."

"Oh, then who is that person?" Chu Hu suddenly realized.

"Why are you all here?"

Shen Qingqing's voice was heard in the distance, and Shen Qingqing was seen riding towards them on a chestnut horse.

Lin Fan smiled and said, "Mr. Guangzhi's candidate has arrived."

Chu Hu and Xiang Long immediately understood and turned to look at Shen Qingqing. After a quick look, they found that Shen Qingqing's body shape was indeed very similar to Lin Fan.

The two men were almost the same height and had similar faces, the only difference being their body shapes.

Lin Fan is a relatively sturdy type, while Shen Qingqing looks a little thin and frail, like a weak willow in the wind.

However, if he wears a scholar's robe, he won't be able to tell the difference.

Lin Fan signaled the guards to let Shen Qingqing in. After Shen Qingqing approached, Lin Fan asked, "Why are you here?"

"My father guessed that you were going to leave, so he asked me to invite you to a banquet." Shen Qingqing said as he jumped off the horse.

Lin Fan and Zhang Guangzhi looked at each other and understood each other's meaning.

"In that case, I will be there later." Lin Fan said to Shen Jingjing.

Lin Fan planned to take advantage of the banquet to discuss this matter with Shen Tiancheng.

If Lin Fan took action by force, with his current strength, he would not be able to suppress the Shen family.

……

Shen family.

"My Lord, your visit has brought honor to my humble abode. Please come in." Shen Tiancheng was standing at the door. When he saw Lin Fan coming, he said politely.

"Master Shen, there's no need to be polite. I will just follow your wishes." Lin Fan said happily.

"please."

When we entered the hall, someone had already prepared a hot banquet.

Lin Fan didn't hesitate and sat on the chair immediately.

Many senior members of the Shen family were accompanying him, but the only one missing was the acting head of the family who rejected Lin Fan that day.
