At this time, Li Zimu and the three people are standing under the gate of the outer city, in front of which is a square, this square is not big, roughly the size of a football field, in front is the inner city gate, there are two small gates set up next to the city gate, and two arches are also set up on the inner city wall on the side, you can go to the attic of the next place.

"How do we get there now?" the spirit asked, looking at the number of doors, turning his head to look at Li Zimu, the entire palace exuding an ancient atmosphere.

"Let's take a look around first" Li Zimu said lightly, raised his feet and walked forward, there should be no mechanism here, after all, it is a place to live, and there are torches on the walls of the square, but you can see clearly.

"Are the weapons of the Qin Dynasty already so strong...... "Chi Ling said in surprise on the wall of the outer city, where a crossbow was equipped behind the alcove.

"The weapons used to defend the city, of course, are the most advanced batches" Zhang Jingyang smiled and said, these crossbows used to defend the city, each of them has the height of an adult, and there are many long crossbows next to it.

"It doesn't seem to be bad at all," the spirit touched the body of the crossbow machine and said in surprise, it was very smooth on it, and there was no trace of being eaten by insects.

Li Zimu picked up a crossbow next to him and weighed it, good guy, this crossbow machine and crossbow arrows are made of iron power wood, the characteristic of this wood is that it is heavy, a cubic meter of iron power wood weighs more than 1,000 kilograms, the texture is tough, the knife and axe are difficult to enter, difficult to process, not easy to deform, the texture is delicate, the corrosion resistance and wear resistance, insects and ants do not eat.

Skillfully put a crossbow arrow more than one meter long on the crossbow machine, this thing he is very familiar with, this thing is called a jack crossbow, although it is heavy, but the operation is very easy, these mechanisms are composed of labor-saving, step on the pedal below, swing the head of the crossbow machine to aim at a lamp outside the city wall.

With a slight step, the crossbow arrows on the crossbow machine shot out quickly with the sound of breaking wind, and finally accurately cut one of the four oil candles on the lamp into two pieces, so fast that the lower half of the candle was still standing on the lamp......

"Awesome!" Chi Ling gave a thumbs up, he didn't expect Li Zimu to know how to operate this crossbow machine, and he shot so accurately.

"This is called a jack crossbow, the weight of the crossbow arrow is as high as dozens of catties, it is specially used to defend the city and shoot horses, the strength is strong, the longest range is more than a thousand meters, and a crossbow within five hundred meters can kill the horse" Li Zimu clapped his hands and said, although this crossbow machine is not broken, but it is covered with dust, obviously no one has used it.

"These crossbow machines are all manufactured to uniform specifications, and there is also the name of the person responsible for manufacturing this weapon engraved on them" Zhang Jingyang looked at the row of jack crossbows on the city wall and said in surprise, these crossbow machines are exactly the same, and the names engraved on them are also exactly the same, obviously this is the same person responsible for manufacturing, I didn't expect that there was already the concept of standardization at that time.

"The weapons of the Qin Dynasty are all unified and standardized weapons, even if this one crossbow machine is damaged, you can immediately take out the corresponding parts to replace it" Li Zimu nodded and said, he had more say in this.

The standardization of the Qin Dynasty's system has reached a very strict level, take this row of jack crossbows as an example, he can be sure that these crossbows are all the same size, and the error is definitely not more than a few millimeters, because if the error is too large, the official responsible for manufacturing this batch of weapons will be beheaded, because each weapon must be engraved with the name of the official in charge of manufacturing.

A general glance at the city wall shows that the style of the building is similar to that of the Great Wall today, but it is a little smaller, and a closed sentry tower is set up at intervals.

"Let's go, let's go to the attic next to us first" Li Zimu turned his head and looked at the two of them and said, this Jieshi underground palace is very big, and it won't be finished for a while, and I don't know which attic this Wang Xueling is in, so I have to go and see each of them.

The three of them walked down from the city wall to the open space of this platform, and Li Zimu did not directly enter the front main gate.

Instead, he turned and walked towards the arch on the left.

"Dust Door" Zhang Jingyang looked at the plaque on the arch and said, he still knows the seal characters. The three of them walked straight through the stone door and inside.

"This piece of the palace is used to be responsible for the life and living of the entire palace, no wonder it is called the dust gate......" Zhang Jingyang smiled and said, there are several halls in it, all of which are used for daily life, as can be seen from the plaque above. For example, the candle library next to this.

The attics here are relatively low, and there is only one floor, Li Zimu gently pushed open the door of the candle garage in front of him, and walked in with his feet raised.

"Why are there so many candles and torches outside, but there are none inside?" The spirit looked at the pitch black and asked in confusion, where they passed by in front, even candles and torches were placed on the side of the road, but there was no light here, and it was pitch black and had to take out a flashlight.

"Fire prevention" Li Zimu said lightly, the whole hall is all high wooden shelves one by one, and some oil candles of the same specification are placed on the shelves, just like the candles they saw on the road before.

There are very few places in the palace to light up, the reason is fire prevention, because the palace is made of wood, so it is easy to be lit, so it is natural to be careful to prevent fire hazards.

During the Qin Dynasty, there were strict regulations on the use of fire in palaces, and there were clear regulations on where lamps could be lit and where lamps could not be lit, and the punishment was extremely severe.

After a few people turned around a little, they went out of the candle hall again, and opened several doors in succession, all about the daily needs of the palace, such as the firewood pavilion for firewood, the attic for boiling water, the attic for cooking, and the attic for cleaning tools.

There are also attics built for the next few people, and there are many, enough for hundreds of people.

"Each area of this Jieshi Palace has a special division of labor, we should be a place for people to stay, that is, responsible for the daily work of the palace" Zhang Jingyang turned around and summed up a conclusion, this large area where the dust gate came in, surrounded by high city walls, there are no other doors to go out, so you can only return the same way.

"Normal" Li Zimu said lightly, the construction of the palace has a regional division of labor, and there are clear regulations on what places are used for what, which has been planned before the construction, and he is responsible for building many palaces, so he is naturally clear about the way.

The three of them returned the same way and walked out of the dusty door towards the side door on the opposite side, and the plaque on the door aroused the interest of the three of them.

I saw that the plaque on the stone gate was engraved with three big characters, General Gate.
