The fur and paws of a black bear are all treasures in the world, let alone such a large black bear.

Such a good thing, of course, Cao Cao and the others were reluctant to throw it directly into the Yangtze River.

With the concerted efforts of more than 100 soldiers, they finally disposed of all the black bears and put them on the ship before the sun set.

As for the black bear meat, it was put in the jar.

Such a big black bear, as soon as it was put on the boat, the whole ship sank a lot.

But fortunately, the boat used by Cao Cao to travel is very large, which can accommodate more than 10,000 people, and it is barely possible to fit these black bears.

Luckily, there were only a few black bears in the area, and no other beasts were coming.

After dark, it's hard to say.

Once at night, these beasts become extremely active.

At that time, even if Lin Chuan sent out all the beasts at hand, he would not be able to save these guards.

After coming to Lin Chuan's farmhouse, Cao Cao couldn't help but ask suspiciously:

"Boy, what has happened on the island in the past two months?"

"Why is there such a giant beast? More than one? ”

"And the boy, why did you tame so many black bears?"

When he first came to the island, he encountered this situation, even Cao Cao, who was used to seeing strong winds and waves, was really incomprehensible.

Lin Chuan was also a little crying and laughing.

Anyway, the experience of this time is too magical.

Even Lin Chuan, who is already a traverser, can't accept it.

After listening to what Lin Chuan said, everyone was silent.

Not that shocked, but incredible.

This kind of thing can only happen in legends!

But Cao Cao didn't expect that this desert island was far more vast than he thought.

Four islands, and the other three are much larger than this one.

By this count, the island is bigger than a county town.

However, Lin Chuan did not tell them about the mysterious power on this island.

Otherwise, Cao Cao would inevitably have to think of himself as an immortal again.

Lin Chuan really jumped into the Yellow River now and couldn't wash it away.

It's not that immortals are derogatory terms, and it's not good to be said to be immortals, but Cao Cao is Cao Cao after all.

During the Three Kingdoms period, there were many local droughts and other disasters.

What if Cao Cao wanted to "do it" and avoid these disasters at that time?

You can't really be like a god, right?

Whether it is an immortal or not, Lin Chuan knows too well in his heart.

Moreover, the punishment for false gods in ancient times was very severe.

Therefore, Lin Chuan would not recognize the title of immortal no matter what.

After all, I don't live up to my name, so it's better to be pragmatic.

After all, most of their abilities come from the system.

"Boy, you said you had a surprise before."

"Now that I have skillfully forged the hundred forging steel, I specially came here, and I hope the young man will tell me."

Cao Cao stood with his hands in his hands and said indifferently.

Lin Chuan smiled indifferently:

"I've been ready for you a long time ago."

"This is it."

With that, Lin Chuan returned to the house and picked up a few drawings from the table.

These drawings are how to make simple grenades.

The grenade requires a lot of steel and black powder, both of which are indispensable, and the most important thing is that there are steel balls in it.

Grenade damage alone is not enough, and it must be equipped with steel balls to work wonders.

Moreover, grenades that simply use black powder are only more powerful.

But the explosion range was low, there was no sputtering of steel balls, and most importantly, the amount of black powder required was too high.

Although there is no shortage of black powder in later generations, it is still very lacking for the current Boss Cao.

Therefore, Lin Chuan first asked them to implement the method of filling steel.

With this, it is possible to make a grenade.

"Young man, what's the use of this?"

Cao Cao really didn't understand it, and he couldn't understand this drawing, it seemed to be something made into a sphere.

No matter how you think about it, it's not as real as a knife or a gun.

"You'll know when you make it."

"Specific things are written on it, and if you want to use it to build, you must remember to use fire to lead the wire, that is, to light it here."

Lin Chuan smiled indifferently, pointed to the things on the drawings and continued:

"Remember, you must not have people around during the test, and you must leave it in a place where there are many obstacles."

"Otherwise, the shock wave caused by the explosion and the steel balls will kill people."

Hearing what Lin Chuan said so mysteriously, everyone immediately scratched their heads.

They just don't understand.

What is the use of such a small sphere?

Can it still explode?

Even if it can explode, where will it have such a big effect?

But looking at Lin Chuan's appearance, Cao Cao had no choice but to agree.

But in reality, he was still very hopeless about this thing.

I didn't expect the surprise to be this.

Lin Chuan couldn't help it.

I can't make grenades on the island, so I can't show them how to do it.

If not, they wouldn't have reacted that way.

A grenade, that's an absolute killer.

As long as it is used, it is simply a dimensionality reduction blow to the current enemy.

If you throw it away like this, at least dozens of people will have to die.

After all, ancient people like to get together when they fight, and they don't know what grenades are, and they can't block them.

Whether it's defending or besieging a city, grenades are a very practical thing.

"And this."

Lin Chuan continued:

"This is called a fire bolt, you can understand it as a crossbow, but its power is much stronger than a crossbow, forget it, you will know when you build it."

"The specific usage is similar to a bow and crossbow, as long as you pull the trigger here, you can fire bullets."

"Basically, ordinary armor, even the armor of the tiger and leopard riding today, can't withstand this bullet."

Hearing this, everyone immediately gasped.

What?

What kind of bow and crossbow can do this?

The armor that the tiger and leopard ride today is made of genuine forged steel.

This kind of 100-forged steel, even if it is made of the same 100-forged steel, may not be able to shoot through.

And yet this thing can, and it's still so far away?

Good stuff, it's definitely good stuff!

Cao Cao immediately took it with a smile.

Compared to the sphere of unknown meaning just now, this one is more realistic.

With this, when defending the city, it is definitely a big killer.

Lin Chuan shrugged his shoulders and said:

"At present, there are only these two, what you have to do now is to quickly improve the strength of the army."

"With grenades and firearms, it will be much easier to fight the Sun-Liu coalition army."

Hearing Lin Chuan's words, Cao Cao suddenly nodded heavily.

How can that be fake?

This thing called the fire gun has a much farther range than the arrows of Soochow.

If you use this thing, if you fight in the Red Cliff, you will fall into an absolute advantage!
