"Such a big house, it should be able to accommodate a lot of people, right?" said Chi Ling as he held a flashlight and followed behind Li Zimu, they had already passed through a lot of houses before, and the specifications inside were all the same, a bed, a table, and other decorative things.

"I can't live too many people, if you want to live for a long time, you must have a lot of candle lighting, the cave is not ventilated, the air circulation is poor, and you have to die for a long time" Li Zimu said lightly, there should be a vent in this cave, but after all, it is a minority.

And the palace is built at the bottom, carbon dioxide is denser than oxygen, although the molecules are constantly moving, but oxygen is mostly on the upper layer, even if there is a vent will not suffocate people, but after a long time, the air will become turbid, and it will become poisonous after a long time.

"This room is finally not inhabited," said the spirit as he looked at the plaque outside the room, there were many rooms in this corridor, but most of them were houses, and this was the third room used to store things in addition to the library and the library I saw just now.

"Firewood room, do you put firewood" Chi Ling looked at the two words on the plaque and said, she actually didn't know the previous word, but Zhang Jingyang was next to her as a translator, as for asking Li Zimu, he would not answer this kind of mentally handicapped literacy question......

Li Zimu looked up at the plaque and didn't speak, in ancient times, the firewood room was not just used to stack fuel firewood, but more used to put sundries, it is not an exaggeration to say that it is a utility room, and any messy things that are not used much can be thrown in it.

Gently pushed the door open and collapsed in, Li Zimu shone the surroundings with a flashlight, saying that it was called a utility room, but the things were placed in an orderly manner, looking more like a kitchen, and the table was full of cutlery.

There are many other tableware with a clear division of labor, and there are complete and diverse varieties. And the material of these tableware is different from the terracotta used by ordinary families at that time, and the tableware here is mainly made of jade and celadon, and the cost is relatively high, but for the wealthy Xiang family, it is still a matter of sprinkling water.

"Eh, this can't be made of glass, is it? Is there already glass at that time?"

"It's been there for a long time, but it's just called colored glass at that time," Li Zimu picked up a glass bowl and looked at it and said, long after the Chinese people mastered the smelting technology of bronze, they also mastered the production of glass.

Because at that time, people found this translucent and shiny little piece in the waste residue left over from smelting bronzes, so they collected them and processed them a little, and they changed into a beautiful color utensil, and people called this material glass.

The scientific name of this substance is now called silicate compound, which is the main material for melting glass, but at that time, it was not possible to refine it into a fully transparent one, in fact, glass is glass.

Looking at the condition and workmanship of this bowl, it can be sold for a lot of money if it is taken out and sold, but Li Zimu is not poor enough to make money from this thing, and after putting the bowl on the table, he looked around again, there was nothing else of high value, and turned around and walked out.

And Chi Ling thought that this color was very beautiful, so he took one and put it in his bag, and went out with Zhang Jingyang behind Li Zimu.

"Sword Casting Pavilion, I finally found a good place" Li Zimu looked up at the plaque on his head and said with a smile, he had passed through so many rooms from the main hall, and only this room made him more interested, and the previous ones were of little use to him.

"Is this a place dedicated to forging weapons?" asked Chi Ling curiously, she was still quite curious about the Sword Casting Pavilion, she didn't know how the famous swords in ancient times were cast, and they couldn't reach the level of modern craftsmanship.

Li Zimu nodded, pushed open the door and walked straight inside, and the first thing that caught his eye was three waist-high sword-casting platforms.

"Well, that's good" Li Zimu nodded and said with satisfaction, compared to the blacksmith platform in the Yu family's ancestral house above, the equipment here is undoubtedly much more professional, but the iron-making tools on the platform are more than twice as many as those in Yu Wen's house.

And what he was most interested in was not this, but the three melting pots next to the three stone platforms.

Walking straight towards the first furnace, Li Zimu took a closer look, the shape of the furnace was designed to be very domineering, the vents at the four corners were carved into lifelike dragon heads, and the furnace body was engraved with many complex patterns, and the front was engraved with three Chu seals: copper smelting furnace.

Li Zimu smiled and walked straight towards the second furnace, the design of the first two furnaces was the same, but the material looked different, and the second furnace was engraved with an iron-making furnace.

What pleases Li Zimu the most is not the two furnaces in front of him, but the last one, the whole furnace body is swarthy, and the appearance is very different from the previous two furnaces, and the size is much smaller, and there are also three words engraved on them: fine iron furnace.

Obviously, there is a clear division of the materials used for the three furnaces, the first is used exclusively for copper, the second is also used for ordinary iron ore, and the third is the most valuable, because it is used to refine special materials, such as iron mothers and other metals with higher melting points.

Looking at these three furnaces, Li Zimu couldn't help but feel a little happy in his heart, he was still worried that there would be no tools when the time came to forge the sword, but he didn't expect that it would take no effort to get it, and this Sword Casting Pavilion was an excellent place to forge swords.

Not only are there furnaces that can smelt metals with a high melting point, such as iron mothers, but there are also ready-made sites, various tools, and of course, if there are raw materials, which is excellent.

Thinking of this, Li Zimu raised his flashlight and looked at the rest of the house, this house was much larger than the ones that went first, in addition to the three furnaces and stone platforms, there was still a large part of the spare space.

And these places are full of wooden shelves, on which a lot of weapons have been placed, there are swords, there are spears, and there are some relatively small ones such as flying knives and other hidden weapons and arrows, etc., Li Zimu looked at it carefully, most of them are made of iron, which belongs to the ordinary category, which is the weapon used by ordinary people.

However, there are a few weapons that can be considered of good quality, such as the two spears and two longswords on the last shelf, both made of fine iron, and one spear is even made of iron mother.

The people of the Xiang clan are more inclined to use spears, so they have more experience in the creation of spears, and as for the sword, it is a little insufficient, so this Yu specially found the current sword-casting master Ou Yegong to cast a sword for him, and although Yu Zi is not as powerful as Ou Yegong, the sword is still very good.
