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

The ignition point of white phosphorus is extremely low, only over 30 degrees, while the temperature in the secret room is only over 20 degrees, so Lin Fan concluded that there must be a friction heating mechanism at the wick of the oil lamp to ignite the white phosphorus inside.

Lin Fan followed Nian Fu all the way to the place where the weapons were stored.

There are various kinds of weapons displayed here, including all eighteen kinds of weapons.

Moreover, after Lin Fan had come into contact with these things more often, he could tell the difference between good and bad, and naturally he would find that the weapons displayed here were all of the best quality.

When Lin Fan saw a long iron spear, his eyes lit up and he walked over and took it in his hand.

This gun was extremely suitable in terms of both material and style, which made Lin Fan like it.

It's just that this gun is too heavy, weighing about 70 kilograms. Lin Fan has no problem lifting it or practicing with it, but if he takes this gun to fight the enemy, Lin Fan has no confidence at all, and even feels that he might die on the battlefield.

It was because the spear was too heavy. According to Lin Fan's arm strength, the spear was just a pointed firewood stick and could not exert the toughness that a spear should have.

Seeing that Lin Fan liked it, Nian Fu explained to Lin Fan: "This spear is called the Green Water Dragon Spear. It weighs 72 pounds and is made of fine steel. In my opinion, it is not suitable for Fan'er. Take another look."

Lin Fan nodded and said, "That's true. The weight of this gun is not something I can lift to kill the enemy. I might even die because of it."

As Lin Fan spoke, he put down the Green Water Dragon Spear and looked at other weapons.

Lin Fan picked up another Fang Tian Hua Ji, which was only slightly lighter than the Bi Shui You Long Spear, but it was also not something Lin Fan could control.

After picking out several weapons in a row, Lin Fan felt that none of them were very suitable, and he couldn't help but feel a little discouraged.

"Haha, Fan'er, since you can't find a suitable weapon for the time being, you might as well pick a weapon for self-defense, or a piece of armor would be nice too." Nian Fu said with a smile.

Lin Fan didn't need armor. The previous set of armor was the one carefully selected by Nian Gui, and Lin Fan liked it very much. However, Lin Fan still needed a weapon for self-defense, so he turned his attention to the rack of short weapons.

There are many blunt weapons such as whips and maces placed on the shelves. Although these blunt weapons cannot penetrate armor, they have great lethality.

Armor can protect against arrows and swords, but it does not provide much protection against blunt weapons such as whips and maces.

After being hit, the bones may be broken, or after being hit on the head, the skull may be shattered.

However, Lin Fan did not like this type of blunt weapon because it was too heavy and each attack required a great deal of strength, so Lin Fan rejected it.

Since blunt weapons don't work, Lin Fan can only look at swords.

On the sword rack, there are many swords that are shining with cold light. Just at a glance, you can tell that they are extremely sharp.

"These are the swords that the master has collected over the years. They are all treasures that can cut through iron like mud and blow away hair. The master himself is reluctant to use them, so he wants you to get them." Nian Fu explained and joked.

"Hahaha, then I have to pick the best one, and my uncle will be so heartbroken." Lin Fan responded with a smile.

The weight of swords and knives can basically be very different, and they are all extremely light, so it is very suitable for Lin Fan to hold them.

So Lin Fan doesn’t have to worry about the weight, he just needs to consider whether he likes it or not.

Finally, Lin Fan picked out a relatively plain sword. The blade was three feet three inches long and there was nothing carved on the sword. It looked no different from an ordinary sword.

"Fan'er has good eyesight. This sword is called the Gentleman Sword. It is a sword that can cut through iron like mud. Other swords may not be comparable to this sword. Of course, this is also the family head's favorite sword." Nian Fu said with a smile.

"Oh? Gentleman Sword? This name is good. Then I want this sword." Lin Fan said.

Nian Fu nodded without any objection. After all, these were all Nian Gui's collections, and Nian Gui was training Lin Fan as his son and the next head of the family, so naturally he would not have any objection.

"How about trying this sword with something?" Lin Fan looked at Nian Fu and asked.

Nian Fu took out a few large coins from his pocket, handed them to Lin Fan, and said, "Try this."

Lin Fan placed a few large coins on the ground, then drew out the Gentleman Sword and chopped at the coins.

Lin Fan didn't use much force, but the coins were cut like tofu.

"What a great sword! What a great sword!" Lin Fan couldn't help but admire.

Lin Fan pulled out another strand of hair, placed it on the sword blade, blew it gently, and the hair was cut off.

Lin Fan had never seen such a sword before. He had only seen the adjective "cutting iron and cutting hair" in novels and on TV.

I didn't expect to see this kind of sword with my own eyes today, and I couldn't help but feel excited.

"How is it? Are you satisfied?" Nian Fu asked with a smile.

"It's really a precious sword." Lin Fan couldn't let it go.

"But which long weapon should I choose?" Lin Fan murmured, his eyes moving to the upper weapons rack.

"Why not choose a spear?" Nian Fu suggested.

Nian Fu walked to the side and squatted down. Only then did Lin Fan see that there was a long wooden box on the ground.

Nian Fu opened the long wooden box, and saw a long spear inside the box.

Nian Fu took out the spear, handed it to Lin Fan, and said, "Try it, how is the weight?"

Lin Fan took it and found that it was made of wood, but the weight was just right and the toughness was excellent. Lin Fan nodded with satisfaction.

The production of a good lance is extremely complicated. Lin Fan can't remember the specific process, but he remembers that it takes more than three years to make a good lance.

However, such a long period of craftsmanship has made the shaft of the lance extremely hard, almost not much softer than an iron rod, and much more resilient than iron.

Lin Fan held the middle of the spear with his hand and shook it with force. The spear then shook and formed a graceful arc.

"Yes, it is top quality, and the weight is just right." Lin Fan said.

"It is indeed top-grade, and this spear is also the favorite of the family master." Nian Fu said.

"Well, I will use this spear to rescue my uncle." Lin Fan said, looking towards the north.

……

"General, we don't have many horses left. We can only hold out for another half a month at most."

"It's been half a month. I don't know if the court will send people to rescue. If I had known this, I would have broken through the defense line even if the whole army was wiped out." Nian Gui said with some melancholy.

"General, why don't we just fight them?" the adjutant advised.

"Wait another ten days. I promised you that I would take you back. If there is no reinforcement after ten days, then we can only fight our way out."

Nian Gui looked towards the enemy camp, his figure seemed a little old.
