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

When Qin Shian saw Lin Fan wake up, he didn't bother to say anything to Master Kong Wen. He rushed to Lin Fan and shouted, "Brother, you're okay. I'm so glad you're okay."

Lin Fan patted Qin Shian's head gently, forced a smile, and said to Qin Shian: "Shian, I'm fine. You can't be rude to Master Kongwen in the future. Do you hear me?"

"Okay, I understand. I will apologize to that old bald donkey...Master right away." Qin Shian said.

Qin Shian originally wanted to call Master Kongwen "Old Baldy Donkey", but then he remembered that he had become Master Kongwen's disciple, and it seemed that after becoming a disciple one should call him "Master", so he changed his name to "Old Baldy Donkey Master".

"Haha, brother Shi'an is really a real person." Chu Hu's heart finally settled down. He was amused by Qin Shi'an's words and started laughing immediately.

Chu Hu smiled, and the people around him also laughed, and the atmosphere gradually became lively.

"Old bald master, I was wrong. I shouldn't have said that." Chu Hu said to Master Kongwen.

"Hahaha, disciple, it's okay. I like you like this." Master Kongwen said to Qin Shian very kindly.

"Hehe." Qin Shi'an smiled innocently, and seemed not to resist Master Kongwen, probably because Master Kongwen saved Lin Fan.

"Master, have you already accepted Shi'an as your disciple?" Lin Fan asked doubtfully.

"Yes, I see that Shi'an has a peculiar physique. With his divine power, he is able to conquer the battlefield."

Listening to Master Kongwen's words, Lin Fan nodded. Qin Shian's supernatural power was indeed enough for him to dominate the battlefield, which Lin Fan was a little envious of.

"But if he were to meet those who rank among the top few in the world today, Shi'an would still suffer a loss. So I plan to pass on my lifelong martial arts to him. It will be a great help to you in the future. I was unable to seek your consent, so I hope you will forgive me. Amitabha." Master Kongwen said.

Lin Fan didn't know how skilled the top few of the Thirteen Heroes in the World were at martial arts, but if Shangguan Ren wanted to kill Lin Fan and his men that day, Lin Fan and the others could only delay for some time if they attacked together. Lin Fan was very clear about this.

But Lin Fan was not sure how strong the one ranked ahead of Shangguan Ren was, but he was definitely stronger than Shangguan Ren. As for how strong the number one in the world, Huangfu Pengwu, was, Lin Fan didn't know, but he should be a terrifying existence.

"Thank you very much, Master. Shi'an will have to rely on you in the future." Lin Fan said.

"It's okay. I like Shi'an from the bottom of my heart." Master Kongwen said with a smile.

Lin Fan wanted to sit up, and Chu Hu came over and said to Lin Fan: "My Lord, don't move lightly. If something happens again, what will we do?"

"Hahaha, this pill of mine will ensure that you, the donor, will be safe and sound, and will be back to normal tomorrow. You just need to move around to allow the power of the medicine to spread." Master Kongwen said with a smile.

Hearing this, Chu Hu didn't say anything, and he and Qin Shian carefully helped Lin Fan up.

"Thank you, Master, for saving my life." Lin Fan said gratefully.

"I only saved you, the little donor, but you are working for the well-being of all people in the world. If anyone needs to thank you, it should be you, the little donor." said Master Kongwen.

"Haha, Master Kongwen saved the Marquis, and the Marquis wants to save the people of the world. Isn't it equivalent to Master Kongwen saving the people of the world?" Xiang Long joked.

Everyone couldn't help laughing, and the atmosphere gradually became lively again.

Lin Fan felt a little weak at first, and he had no strength in his whole body. But after he got up and took a few steps, a warm current in his abdomen gradually spread throughout his body. Soon he gained strength and was able to walk on his own without any help.

Everyone was amazed, even Lin Fan was amazed, and asked, "Master, do you have the formula for this elixir?"

Lin Fan knew very well what it meant if this kind of elixir had a formula and was developed.

Master Kong Wen shook his head and said to Lin Fan, "I don't know either. This elixir was given to me by my master when I was young. As for where my master got it from, I don't know either."

Lin Fan did not ask any more questions. This kind of panacea was extremely rare. It might take a long time, even more than a thousand years, to achieve the current effect. It was rare to have one or two pills.

Lin Fan looked at Xiang Long again and asked, "How's the gunpowder?"

"I've asked my brothers to deal with it. I think there will be a reply soon. I'll go take a look." Xiang Long said.

"Well, go ahead." Lin Fan nodded.

If there is no leakage, the gunpowder can still be used after it is dried. However, after a leak, it will definitely not dry in a short period of time, especially since the gunpowder cannot be too close to the fire. Even after it dries, if it rains, it will inevitably get damp again, so Lin Fan had to consider other methods.

While Lin Fan was stretching his limbs, he began to think about how to conquer the Xiongnu royal court.

The Xiongnu royal court is located in the heart of the grassland and is one of the few large cities in the grassland.

However, the city wall was indeed made of rammed earth, not bricks and tiles, but it was very thick, and it would be impossible for more than 2,000 people to attack it.

what can we do about it?

Many ideas flashed through Lin Fan's mind, but he rejected them all one by one.

Suddenly, Lin Fan had a bold plan, but he absolutely could not bring it up now, so he pretended nothing had happened.

The next morning, after a comfortable sleep, Lin Fan felt refreshed. All the discomfort in his body disappeared, and he even felt better than before.

The rain stopped in the middle of the night. The sky was cloudless and the morning sun was already shining on the horizon, looking vibrant and energetic.

"My lord, most of the gunpowder has been damp, but after being baked in the second half of the night, it has gradually dried up. Some of it can be used directly, but there is not much gunpowder that can be used directly." Xiang Long ran over to report.

"Well, let's dry it in the sun for another day, and at the same time, relight the gunpowder at a distance from it to ensure that there will be more gunpowder available at night." Lin Fan said.

"Yes."

The day passed quickly, and the gunpowder still did not dry out, because after noon, the weather became gloomy again, but fortunately it did not rain.

Lin Fan ordered each of them to assemble a few grenades and explosives with usable gunpowder as a backup.

Lin Fan himself took Chu Hu and Qin Shian away from the tent.

"My lord, where are we going?" Chu Hu asked.

"The Xiongnu royal court." Lin Fan asked calmly.

"Ah? My Lord, are we three going to attack the Xiongnu royal court?" Chu Hu said in shock.

"No, it's me myself." Lin Fan said with a smile.

"What? Lord Marquis, this is absolutely not possible." Chu Hu advised, his face full of anxiety.

"I am not a fool, so I will not attack the Xiongnu court. I plan to sneak into the Xiongnu court and assassinate the Xiongnu Chanyu. When the city is in chaos, you can lead your troops to blow up the city gates and help me."
