Jing Ke and they have already opened dozens of treasure chests, and they are more experienced, and when they go over, they will not alarm the extra stone people.

After getting five treasure chests in a row, Mu Han obtained a large number of skill books.

"The national war is fought with comprehensive strength, and comprehensive strength involves all aspects, and in this copy is all kinds of basic materials, from skill books and weapons and equipment drawings to directly improve the basic strength of the army."

The national war is not fought with high-end combat power, and high-end combat power can change a war, but it may not necessarily change the overall trend.

The national war can only be sustained if the comprehensive strength comes up.

Therefore, these rewards are all materials to improve the overall strength from all aspects.

They entered another room.

"Lord, this place is a lot bigger."

Mu Han took a look, the room was more than twice as large, and there were also two stone doors on the opposite side.

There were also a lot more stone people in the room, more than 500 people.

"Maybe there's something good."

The situation here is too far from the others, and the stone man doesn't know what's going on.

I checked around, and there was no difference except that there were more stone people.

Jing Ke: They began to act.

But soon there was an accident, the stone man here is relatively strong, and a third of the corrosive liquid in the bottle cannot corrode the stone man.

"A whole bottle has to be used." Jing Ke said.

A whole bottle is a whole bottle.

"Even if you use it, maybe there's something really good."

One whole bottle, all the stone people killed more than 400 bottles of corrosive liquid, Mu Han can afford to use it.

Bottles of corrosive fluid smashed through.

The corrosive liquid smashed through it, and it sizzled on the stone people, and it quickly corroded them.

Mu Han, they moved forward cautiously.

"Lord, the stone people here are much more sensitive."

Jing Ke walked ahead, originally according to his experience, he would not alarm the stone man, but there was a distance of eight meters to attack Jing Ke.

Jing Ke immediately threw a bottle over, and then quickly retreated.

It also took a little longer to corrode these stone people, and these people seemed to be enhanced versions of ordinary stone people.

After tossing for almost an hour, Mu Han and the others still got the treasure chest.

"Hope for something good."

Mu Han prepares to open the treasure chest.

Slowly open the treasure chest.

"Ding System Prompt: Congratulations to the player Fujiwara Chineki for obtaining a 500-ton ship shipbuilding blueprint."

Hearing the system prompt, Mu Han became ecstatic, the 500-ton level can increase his naval combat power by a cut.

"Good stuff, there's really a good thing."

This is too important, Mu Han's current ship is only 300 tons, and it is not convenient to do anything.

The most important thing is that there is no way to protect himself, if other forces want to attack Mu Han, Mu Han's current strength will not be able to stop it.

Now that the level of the ship is one level higher, Mu Han's naval combat power will soar a lot.

"I have to leave, I can't let Yuma Asano find out, you continue to explore, you leave a mark, I'll come back in the evening."

Before dawn, Mu Han left in a hurry.

This harvest is very large, there are 500-ton ship blueprints, and the strength of the territory can be improved a lot.

Mu Han slipped back again, at this time he was not important in the eyes of everyone, and was often ignored.

When the war started, Mu Han also tried to hide as far away as possible.

Staying away, Mu Han didn't attract much attention from others, and he only appeared when Yuma Asano summoned everyone in.

After another day, Asano and the others violently captured two more treasure chests, and then they decided to go inside.

In the evening, Mu Han quietly left to look for Jing Ke.

By the time they found Jing Ke, they had already opened more than a dozen treasure chests and obtained a large number of good things.

"Lord, we found a secret room, but it was difficult to open, and we tried many methods to open it." Jing Ke said.

After listening to this, Mu Han became interested and asked Jing Ke to take him to have a look.

Jing Ke took Mu Han and turned around a few rooms, and then went to the secret room he said.

In fact, it is not a secret room, the door gap is very large, and one hand can reach into it and see the situation inside.

The stone people inside are not ten meters apart, but close together, I don't know how many people there are.

"Lord, these two doors don't have chains, we can't pull and push."

Mu Han also tried other methods, but there was really no way to open the door.

There are a lot of stone people inside, like terracotta warriors, forming a military formation.

If there is a treasure chest in this, it must be very difficult.

After more than half an hour, he still couldn't open it, so Mu Han said, "Let's see if we can corrode this gate." ”

Corroding the gate, I don't know how much corrosive fluid is needed.

Immediately poured the corrosive liquid of the reagent bottle on, this door can indeed be corroded, but it is too heavy.

"We just have to corrode a hole and get one person in."

Sure that it can corrode, Mu Han wants to try it, and use more corrosion liquid.

Dozens of bottles of corrosive liquid were poured at once, and after waiting for a few minutes, the outer layer of stones was scraped off with a knife.

"Keep corroding."

After using more than two hundred bottles of corrosive liquid, Mu Han and the others finally made a big hole in the door, and Mu Han felt that they were now tomb robbers, digging a hole.

After digging up, the army could only go in one by one, and it took another half an hour or so for Mu Han and them to enter the interior.

"Lord, this is too much, it's simply an army."

After entering, Mu Han and the others saw a neat phalanx, and there might be three thousand people in total.

"Let's see if there is a treasure chest first, and if there is no treasure chest, you won't get it."

An army of three thousand stone men, one bottle of this one, also needs three thousand bottles of corrosive liquid, if there is no good thing, then you don't want to waste it.

"Lord, there seem to be two treasure chests in the middle."

Jing Ke and the others found the gap from the side and saw the treasure chest.

"Distribute all the corrosive fluid, and bring some every month, just in case."

Mu Han always felt that it was not easy here, so the soldiers must be careful.

The corrosive fluid was sent down, and the soldiers were ready.

"Okay, throw it together."

There were two treasure chests, Mu Han was not polite, and everyone directly threw out a bottle of corrosive liquid.

The corrosive liquid smashed on the stone man, and the stone man opened his eyes and killed them from a distance of more than twenty meters.

"Throw another bottle."

The army of stonemen will kill them, and if they are not eliminated, they will have nowhere to run.

Another bottle was thrown, and then Mu Han and the others retreated to the door.

These stone men did not walk very quickly, and finally stopped moving when they were more than ten meters close to them.

"Whew"

Seeing the stone man stop, Mu Han and the others finally breathed a sigh of relief.

"Everyone be careful, throw two bottles out at a time, and then quickly retreat."

The lives of soldiers are also important, Mu Han does not dare to take risks, let them be careful.
