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

"This……"

Emperor Liang was extremely hesitant. From the bottom of his heart, he wondered if Lin Fan could have such ability?

"Father, I am willing to guarantee it with my life!"

Lin Fan said in a deep voice, his handsome face full of smiles.

"Prince, this poison gas is no joke. If you are not careful, it can kill people in an instant!"

Nian Gui looked worried. He thought that his foolish nephew dared to share the country's worries, and it was good that he had such a heart.

"Father, since elder brother wants to try, why not grant his wish?"

Lin Rui advised.

A hint of smugness flashed across his face. He had already made plans to wait for Lin Fan to fail, and then mock him in every way.

"Your Majesty, you can let the eldest prince give it a try. If it is effective, it will be a great contribution to the country." The queen also advised.

If Lin Fan died accidentally from poisoning, wouldn't it save a lot of trouble?

"In that case, Fan'er, you can try to study it. But remember, don't hurt your body."

Finally, Emperor Liang nodded and agreed.

After all, Lin Fan is the eldest son, and there is a high probability that he will inherit the Daliang Kingdom.

Although he was stupid, deposing the eldest son and enthroning the youngest son was a taboo since ancient times, not to mention that the Nian family was standing behind Lin Fan.

"Thank you, father. I will keep it in mind." Lin Fan smiled and bowed.

"General Nian has now returned victorious, and we should celebrate. Come, give him a reward of 1,000 taels of gold!" Emperor Liang was very happy and looked at Nian Gui.

"It's just a small contribution, what's the point? You can achieve today's achievements thanks to the brave soldiers. If Your Majesty wants to reward, you can give it to the soldiers."

Nian Gui spoke in a deep voice, brushing aside his own contribution.

"Well, then the entire army will slaughter pigs and sheep and take a three-day break, and then we will reward them according to their merits." Emperor Liang was smiling and was quite satisfied with Nian Gui's performance.

He is capable but not arrogant. If not, Nian Gui would not be safe and sound today.

"On behalf of all the soldiers in the army, I would like to thank Your Majesty for his grace." Nian Gui bowed and thanked him.

The banquet went on as usual, but with the participation of the elderly, it became even more lively.

Regardless of whether they were on good terms with the Nian family or not, they all toasted Nian Gui.

Lin Rui watched all this with an extremely jealous look in his eyes.

But when he thought about Lin Fan's plan to study the poisons of Yan State, he couldn't suppress a smile on his face again.

Lin Fan, ah Lin Fan, there is a road to heaven but you don’t take it, there is no door to hell but you come to it.

……

After Lin Fan got the dark green gas, he kept his eyes on the gas.

Having been obsessed with experiments for many years, he was eager to do some research.

But he couldn't leave first, so he could only suppress his inner restlessness and wait for the banquet to end.

Emperor Liang noticed Lin Fan's actions, but did not pay too much attention to them. He just thought that Lin Fan had never seen poison gas before and was just curious.

The banquet finally ended and Lin Fan left the Palace of Tranquil Longevity. He couldn't wait to verify his guess.

Just after leaving, I met Nian Gui again.

"uncle."

Lin Fan said affectionately.

Whether in memory or in Lin Fan's cognition of this body, Nian Gui has always treated Lin Fan very well.

Although Nian Gui had been away fighting for a long time, every time he came back, he would bring some strange and weird things to Lin Fan.

Of course, this time is no exception.

"For you."

Lin Fan subconsciously reached out to take it.

But when it fell into the palm of my hand, I felt a chill quickly.

"This is a bronze buckle made by a famous craftsman from the State of Yan. There is a mechanism inside. If you press it at a critical moment, a silver needle will be ejected."

Nian Gui smiled, and a hint of melancholy appeared on his weather-beaten face.

"Uncle knows what you are thinking, but you are dull after all. Sigh, you should be more careful. If uncle is gone in the future, your situation may not be so optimistic."

Hearing this, Lin Fan was stunned, feeling mixed emotions.

Before Lin Fan could speak, Nian Gui patted him on the shoulder and warned him, "My uncle will go to war again, and you will be the only one in the palace. You must be careful about everything, especially the Queen and Lin Rui."

Although Lin Fan was the eldest son of Emperor Liang, he was not born to the Empress, but to the Imperial Concubine.

But even so, he is still the eldest son, there is no doubt about that.

Of course, it was for this reason that Nian Gui warned Lin Fan like this.

Lin Fan was either deposed or killed by Emperor Liang.

The biggest beneficiaries are undoubtedly the Queen and her son Lin Rui.

"Yes, uncle, I understand." Lin Fan smiled and said lightly.

Lin Fan was naturally well aware of the murderous intentions of the Queen and her son towards him, otherwise they would not have framed him.

At the same time, Lin Fan also understood that the reason why he had not been abolished was entirely because of his status as the eldest son and his uncle's age.

The old man looked at Lin Fan's smile, smiled bitterly, and looked at him with reminiscence.

"When you smile, you look just like your mother."

Nian Gui's hands were extremely rough from holding weapons all year round, but when Nian Gui touched his cheek, Lin Fan did not feel uncomfortable at all, but felt warm instead.

"My mother, how did she die?"

Lin Fan doesn't have many memories of his mother now, but the sadness he feels when he thinks of his mother makes him feel sad.

"Your mother...Alas, you are still young, don't think about it, and don't ask! Otherwise, your uncle can't protect you."

Nian Gui's expression changed, and a hint of murderous intent appeared on his face.

"Forget it, uncle has to go, please take care of yourself."

Nian Gui did not give Lin Fan a chance to speak. He just left a few words and turned away.

Nian Gui's back seemed to be much more hunched, completely different from the demeanor he had when he just returned from a great victory. Instead, he looked like an old man walking unsteadily.

"I will definitely investigate all of this!"

Lin Fan clenched his hands and looked determined.

Although the princes lived in the palace, each prince had his own courtyard.

After returning to the study, Lin Fan glanced at the books on the table, smiled bitterly and shook his head.

"What use are these so-called sage books, other than harming people?"

"Your Highness, are you back?"

The maid Chun Fang heard the noise and hurried over, rubbing Lin Fan's shoulders skillfully.

As the eldest son of Emperor Liang, the only person Lin Fan could order around, apart from the cook, was Chun Fang, his mother's personal maid.

It can be seen how powerless the so-called eldest prince is.

"Chun Fang, light up the oil lamp."

Lin Fan said softly, then took the bottle that Nian Gui gave him in his hand.

"Your Highness, do you still need to study hard?" Chun Fang asked softly while lighting the oil lamp.

Lin Fan shook his head and did not respond to Chun Fang's words. Instead, he carefully looked at the bottle in his hand.

"It's dark green and poisonous. Is it what I thought it was?"

Lin Fan was confused.

If I were in the laboratory right now, I could detect it in minutes.

In ancient times, even a good cook could not cook without rice.

"Your Highness, what an exquisite glass bottle."

Chun Fang looked at the bottle in Lin Fan's hand and spoke.

Hearing this, Lin Fan was stunned for a moment before he reacted.

The bottle in his hand was not the transparent glass bottle used in the laboratory, but a colored glass bottle the same color as a beer bottle.

"I see." Lin Fan slapped his forehead and cursed himself for his occupational disease.

Then, Lin Fan gently opened the bottle, placed the bottle at a distance of two fists, gently fanned the bottle mouth, and sniffed.

Bang!

A flash of fire suddenly burst out from the bottle in his hand, followed by a slight explosion.
