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

The prosperity of a dynasty is undoubtedly closely related to its successors.

When the court officials heard what Emperor Liang said, they began to speculate.

After all, for most of them, what they need is not the longevity of the dynasty, but to choose the right side.

Maintain your own power, keep yourself alive, and keep your family alive.

"Okay, that's all for today."

After discussing the basic details of the meeting with the envoys, Emperor Liang waved his hand and signaled the ministers to leave.

"I'm waiting to retire."

A number of ministers took their positions.

However, Nian Gui was detained by Emperor Liang.

Is this to warn Nian Gui, or to support Lin Fan?

Nian Gui didn't have these thoughts. At this moment, he was looking at his nose, his mouth and his heart.

"Uncle, tell me the truth, if we attack the three kingdoms outside the Great Wall, what are our chances of winning?"

Emperor Liang grabbed Nian Gui's wrist, pulled him to the chair, and comforted him to sit down.

The three kingdoms outside the Great Wall are rich in iron ore and are grasslands, which are extremely suitable for raising horses.

Emperor Liang had been coveting it for a long time.

However, Emperor Liang knew the current situation of Liang State better than anyone else.

Although the State of Yan had been destroyed, the other five countries were still eyeing it covetously.

Moreover, the remnants of Yan State continued to cause trouble within the territory of Liang State.

Although Emperor Liang has his own secret agents.

However, the Jinyiwei failed to catch the person behind the scenes after several investigations.

This made Emperor Liang feel that his Jinyiwei might have been infiltrated.

"If Your Majesty sends troops, the Nian family will definitely help."

Nian Gui clasped his fists and said firmly.

"Well, with what the uncle said, I feel at ease." Emperor Liang smiled, and he seemed to be very close to Nian Gui.

"Come on, set up the banquet. I want to have a few drinks with my uncle."

At the banquet.

Nian Gui and Emperor Liang toasted each other like old friends who had known each other for many years, rather than a relationship between a monarch and his subject.

When they were drunk, Emperor Liang sang Liang songs to cheer up Nian Gui, and Nian Gui played the qin to accompany him.

Even the young eunuch who was serving was shocked by this scene.

After the banquet, both of them had flushed faces and Emperor Liang began to stagger.

Nian Gui struggled to get up, clasped his fists and left.

"Your Majesty, let me help you to rest?" The young eunuch hurried over to support Emperor Liang.

"I remember you have been in the palace for three years, right?" Emperor Liang stood up on his own, not at all drunken.

"Your Majesty, I have been in the palace for three years and three months." The young eunuch said with fear and trepidation.

"Oh, so much time has passed." Emperor Liang nodded.

"Hailong, give him some silver and let him go home." Emperor Liang shouted into the darkness.

"Yes."

Hailong came out and left with the grateful little eunuch.

Just two hours later, a family was murdered, which became a major mystery in the capital.

After leaving the palace, Nian Gui was not drunk. He just looked back at the palace and murmured, "Is this going to consume the strength of the Nian family? But you'd better not touch Fan'er!"

But in Lin Fan's yard, it seemed particularly lively at this time.

"That's it. That's how it tasted. If I hadn't been rescued in time by the general, I might have died on the battlefield." Xiang Long said with hatred in his eyes.

In front of Xiang Long was a bottle of gas, which was exactly the same as the poisonous gas that Nian Gui brought back.

If Xiang Long had not seen it with his own eyes, he would never have believed that even Chen Sheng, the world-famous medical genius, could not crack or replicate the poison gas.

It's so easy in Lin Fan's hands?

Looking at the admiration in Xiang Long and Chun Fang's eyes, Lin Fan himself felt a little embarrassed.

It's just a mixture of smoke and methane, is it worth being so shocked?

If it were possible to have the equipment and facilities, Lin Fan would have wanted to develop potassium cyanide.

After all, Potassium Cyanide and Huo Yuanjia are both Lin Fan’s idols.

"Your Highness, if the poisonous smoke is a drug, how could it kill so many of our soldiers?"

Xiang Long asked in confusion.

In his opinion, the ingredients in the bottle were just pure drugs.

After all, Xiang Long saw Lin Fan insert a bamboo tube into the swamp in the yard, and then he smelled a foul odor.

Lin Fan then inserted the other end of the bamboo tube into the bottle filled with water.

Just count your breaths and you will see the water in the bottle flowing out.

But Xiang Long was just a military man, proficient in all matters on the battlefield, but in other aspects, he was completely clueless, like blowing fire with a rolling pin.

"The gas in the swamp is called marsh gas. It is poisonous and can cause poisoning when the concentration is too high."

"After all, it needs a certain concentration to be effective, and it shouldn't be possible in the vast outdoors!"

As Lin Fan explained, he was also confused.

"It's amazing! Your Highness!" Xiang Long said excitedly, looking at Lin Fan as if he had seen a god.

"Huh? Isn't it outdoors?" Lin Fan asked puzzledly.

"As Your Highness said, the land of Yan is mountainous, and most of our battles with Yan took place in the mountains."

Xiang Long paused, took a deep breath and said: "We have no other choice. We can't afford to waste our rations. The general has no choice but to order us to attack by force."

"But once they entered the mountains, many Yan thieves immediately hid in the caves."

"In the beginning, we were afraid of a trap, so we didn't follow them in and did some exploration. But we were still short of food and grass, so we had no choice but to attack them."

When Xiang Long said this, his face looked sad and his eyes were full of hatred.

"Many brothers have been sacrificed in vain. Your Highness, do you have a solution?"

"Although the Yan Kingdom has been destroyed, some of the Yan bandits still hide in the mountains. I am afraid that many brothers will be sacrificed in vain. Please tell me how to crack it. I will be your slave in the future to repay your kindness!"

Xiang Long's eyes were moist and he saluted deeply.

"Brother Xiang, why do we have to do this between you and me?"

Lin Fan smiled and said, "Brother Xiang, are there many bamboo tubes or passages in the cave?"

Xiang Long nodded and asked, "How did Your Highness know?"

"Brother Xiang, it is actually very simple to break this method."

"We just need to destroy the bamboo tube or the passage, there is nothing to be afraid of."

Xiang Long was stunned, his face was embarrassed, and he said: "We have sent brothers to sabotage before, but the result was that they were either poisoned or killed by the Yan thieves, alas."

"Hahaha, Brother Xiang, don't be sad. I have another plan that can break it." Lin Fan said with a mysterious smile.

Xiang Long was impatient and said quickly: "Your Highness, please speak. I, Xiang Long, would rather work like a cow or a horse to repay your kindness."

Lin Fan wanted this effect, still showing panic, he quickly helped Xiang Long up, and said with some self-blame:

"Although this method is useful, it is against the harmony of nature."

"Your Highness, don't blame yourself. When Mr. Wenhe advised the general to bury the prisoners alive, he also said: it will hurt the harmony of heaven, but not the harmony of culture."

"Besides, the Yan army is called an army, but in reality it is Yan bandits. They have committed all kinds of evil in Yan territory, such as burning, killing, looting, and so on. Your Highness's actions are in accordance with the will of heaven, so there is no need to feel any grudges."

Lin Fan was stunned and asked in surprise, "I never thought that Brother Xiang is so eloquent?"

Xiang Long touched his head and said awkwardly: "These were all words that Mr. Wenhe used to persuade the general. I only remembered a few sentences."
