It's a dark and windy night, a time for murder and arson.

Liu Tan felt as if God was helping them. That night the mountain was pitch black, the moon was hidden in the clouds, and only the blazing fire in the middle of the camp was the most eye-catching.

He didn't go this time, as there was almost no suspense in such a war.

As long as there are no accidents and no heavy rain, there will be no problem.

In fact, there is no need to worry even if it rains, because Mo Shi and his colleagues discovered during their research that black gunpowder is not particularly stable. It is easy to explode but also easy to fail to explode.

Although the chance of not getting it exploded is very small, it will be very troublesome if you encounter it.

So in order to make the black powder more stable, Mo Shi and his team directly added oil into it.

By the way, the fuses were also soaked in oil. Anyway... the oil they used was soybean oil, which was not expensive and affordable!

Liu Tan couldn't help but be shocked after knowing this. They were really cruel, but this was indeed not bad.

While they were waiting, Wei Buyi, sitting beside him, couldn't help but ask, "Your Highness, you brought so much saltpeter and sulfur this time just to... make black powder?"

Liu Tan glanced at him and said, "No, saltpeter is used to make ice. The weather in the south gets hot earlier, and we've been traveling so fast it would be bad if we got heatstroke. And from what I know, the island where Father and the others are is even hotter."

"What about... sulfur?"

"Why else? To keep insects out?" Liu Tan rolled his eyes. "Don't you think there are too many mosquitoes here?"

As for charcoal, there is no need to ask. It is needed for cooking. They did bring coal, but some charcoal is still needed for ignition.

After Liu Tan finished answering, he also felt that the fate of Qie Lan Kingdom... was really coming to an end. You know, he didn't bring so many things with him when he traveled in the past. After all, he was always in the territory of the Han Dynasty, so he just went to buy it when he needed it.

As a result, because this place was not his own territory, Liu Ju prepared things for him as if it were just moving house, and the result was... he got everything he wanted.

Wei Buyi looked at Liu Tan with some suspicion, always feeling that things were not that simple.

He was about to say something when his brother poked him in the waist.

Wei Kang's attack was a bit harsh, and Wei Buyi immediately hissed and turned to look at his brother.

Wei Kang stood up and said, "Let's go out and take a look. Don't stay here and bother His Highness."

Wei Buyi had a hunch that his brother might say something, so he thought about it and followed him out.

After he went out, he rubbed his waist and asked, "Brother, your hand is too cruel, isn't it?"

Wei Kang glanced at him and said, "Better to be ruthless than you who speak without restraint."

Wei Buyi smiled and said, "Don't be nervous. You don't know His Highness. He is a very gentle person. He won't get angry if you ask questions. On the contrary, he will get angry if you don't ask questions and something goes wrong when doing things."

Wei Kang couldn't help but whisper, "I think His Highness is too lenient. He's spoiled you all to the point of losing your minds. This black gunpowder is clearly not something from this world. His Highness has never taken it out before, and now he has no choice but to take it out. Do you still want him to admit that he planned this all along?"

Wei Buyi stared at his brother blankly: "This...what's the big deal? Isn't it a good thing for Your Highness to prepare for a rainy day?"

Wei Kang said, "I haven't spent much time with His Highness, so I don't know what his temper is like, but I've heard that things from the immortal realm can't be easily brought into the mortal world, otherwise the mortal world will be in chaos. And if an immortal takes it out carelessly, they will also face heavenly punishment. Your Highness has now taken it out for His Majesty, risking heavenly punishment. You... do you really have to cause a big uproar?"

Wei Buyi was stunned when he heard this: "Heaven... Heaven's punishment? What will Heaven's punishment be like?"

Wei Kang was speechless. This was not his focus.

But he still said, "How should I know this? It's just hearsay. You know there are many alchemists in Chang'an, and there are all kinds of rumors. Some rumors are naturally false, but this one... I don't think it's false. After all, so many alchemists say it, it must be true."

Wei Buyi was a little anxious: "This... this... what should we do? If His Highness really suffers the punishment of heaven..."

Wei Kang said, "So shut up and stop asking questions. It's also best to have everyone else shut up and stop discussing this matter."

Wei Buyi frowned: "This... even if we don't tell anyone, can we really hide it from the gods in heaven?"

Wei Kang said angrily, "I'm not a god, how would I know? I can only do my best and leave the rest to fate. The rest is up to His Royal Highness the King of the North. You...you better be more careful."

As soon as he finished speaking, he heard a loud noise coming from a distance. The sound was so frightening that it made people shudder.

Wei Buyi swallowed his saliva and said, "Brother, did you just... just feel the ground shaking?"

Wei Kang's face turned pale at this moment: "It's so powerful."

Wei Buyi originally didn't quite agree with Wei Kang's claim that the so-called black gunpowder came from the fairyland. After all, His Royal Highness the King of the Northern Territory brought out so many things that every time everyone thought they were products of the fairyland, but every time they could find the principles of these things in the human world.

Over time, those who had always been around Liu Tan came to believe that the King of the North had to have such wild imagination to come up with such an idea.

Because His Royal Highness the King of the North doesn't look like an immortal at all. He can be angry, happy, and sometimes very petty. He looks like a living person, not the very vague immortal image in their impression.

But now, he seemed to be back to the time when he saw the things Liu Tan took out.

After the first loud bang, the rest of the loud bangs came one after another.

Wei Kang and Wei Buyi looked towards the place where the Qie Lan Kingdom was located. Not only them, but everyone else in the camp did the same at this moment, keeping their original posture and turning their heads to look in that direction.

Many people had awe on their faces, as if it was a punishment from heaven.

Liu Tan stood at the door of the tent, counting the sounds of black powder explosions.

At first he could still count them, but later the sound of the black powder explosions was so frequent that he had no way of counting how many gunpowder barrels the people below had thrown out.

The huge noise covered up all the sounds that could be made by the Qilan Kingdom.

Although he couldn't hear it, Liu Tan knew that the place was probably like purgatory.

He did not pity these people. Too many Han envoys had died at the hands of the Qie Lan State. The population of the Qie Lan State was not large to begin with, so everyone in it might be an executioner.

He turned around and went back into the tent. Sitting there, he actually missed Lu Xuan for a moment.

There was no suspense in this battle, but he was not happy. He just wanted to hug Lu Xuan, and he didn't know why he suddenly felt lonely.

Liu Tan sat in the tent playing with the jade pendant that Lu Xuan had carved for him. He had been away for so long and had no idea what was going on in the Northern Border Kingdom.

When Wei Kang and Wei Buyi came in, they saw Liu Tan sitting there. Although his posture was no different from usual, he looked very lonely.

The two of them stopped and looked at each other, not knowing whether they should continue in.

It was Liu Tan who looked up and saw them and asked, "Are you two standing there as door gods? What's going on?"

It happened that the two of them had just heard something and quickly said, "People have been sent to clean up the battlefield."

Wei Buyi took the initiative to order this matter. At that time, Wei Kang was a little puzzled. Why clean up the battlefield so early?

Then he remembered what Wei Buyi had said at the time: "Your Highness is soft-hearted and cannot bear to see such a scene."

Wei Kang’s first feeling when he heard this was: Are you kidding me?

He was a ruthless man who was willing to run and stab Wu Shilu. Are you telling me that he can't stand seeing people die?

Even without mentioning this, the envoy was beheaded in front of him two days ago, but His Royal Highness the King of the North did not seem to feel any discomfort.

However, just now when Wei Kang looked at Liu Tan sitting there alone, he suddenly understood what Wei Buzhi meant.

It was a feeling he probably couldn't describe, as if someone like him shouldn't be shown a scene of hell on earth.

After hearing this, Liu Tan put away the jade pendant and said, "I should be able to sleep well tonight. I'll rest here for two days before leaving."

Wei Buyi asked in surprise, "Rest for two days?"

Liu Tan responded, "Well, everyone hasn't gotten a good night's sleep these past two days because of those idiots. We're not used to the climate here to begin with, and we'll have to rest for two days."

Of course, the most important issue is that there is still a tough nut to crack, which is Jiaozhi.

Jiaozhi is not Qilan. It has a long coastline, a relatively developed economy, and a large population. Even if Liu Tan takes out the powerful weapon of black gunpowder, he must be careful of a disaster.

After resting for two days, they set off again.

The Qielan Kingdom no longer exists, and there are not even a few people left.

Wei Buyi once asked Liu Tan what to do with the remaining captives of the Qie Lan Kingdom.

Liu Tan's response at the time was particularly cool: "Let them fend for themselves. Are you still going to take them on the road? Or send them back to Chang'an?"

Oh, speaking of this, Liu Tan suddenly remembered that since the Qie Lan Kingdom had been destroyed, he should also send a message to Chang'an. It would be a victory no matter how big the battle was.

When Liu Ju, who was far away in Chang'an, received this good news, he felt that it had come as expected.

He felt at the time that Liu Tan was a fierce dragon crossing the river, and once he arrived in Lingnan, he would inevitably have conflicts with the local tyrants.

But he didn't expect that Liu Tan would be able to deal with the Qilan Kingdom so quickly and wipe out the whole country in one go.

It's only been a few days? Back then, it took the Han Dynasty several days to defeat Yelang.

Liu Ju knew there must be something wrong when he saw the brief report on the victory.

However, after the Qielan Kingdom was Jiaozhi. Liu Ju couldn't help but worry and wrote a letter to Liu Tan, asking him to be careful with Jiaozhi and to ask for help if he needed anything. It was not shameful to ask his brother for help.

However, when Liu Ju's letter reached Liu Tan's hands, the envoy from Jiaozhi was nodding and fawning to Liu Tan, almost ready to grant his every request.
