"Hydrated lime doesn't work."

Pinching his small chin, Tang Guan pointed out the problem accurately: "I remember that only quicklime can be corroded with high intensity after contact with the skin, and hydrated lime is not good." ”

"Nonsense, I taught you this knowledge, can I not know?"

After sneering, Zhou Li took the bag of hydrated lime into his arms. Then he took out a delicate wooden box from the dark compartment on the side, opened it, picked up several leather bags in the box, and shook it at Tang Guan.

"Refractory Stone..."

Tang Wan recognized at a glance what the contents of the small bag were, and at the same time, she realized that the three thousand camps had stored a pile of hydrated lime not for "use", but for use.

Chinese, it's amazing.

"Hydrated lime and white stone can make this refractory stone."

Zhou Li took out a small and delicate dark red stone, about the size of a knuckle, and shook it next to the candlelight on the side. In an instant, there was a faint heat in the stone. And the candlelight was extinguished instantly, and the light was gone.

"That's not right."

Tang Wan hissed, took the refractory stone and looked at it repeatedly, and said with some hesitation: "The refractory stone can absorb heat and prevent the fire from burning the camp." But the 3,000 battalions themselves do not have a fire army array, and they rarely use fire to attack, why do they store so many refractory stones? ”

"The three thousand battalions themselves are rangers, and the refractory stone does nothing but slow them down on the march. But according to my estimates, there are at least more than 100 refractory stones in this outpost, and even if there is a fire that burns down Shangjing, these refractory stones can control the fire. ”

Zhou Li looked at the box of refractories, stretched out his hand, and put a few of them into his arms. Refractory seems to be a cheap raw material, but it takes a lot of manpower and material resources to make it. This box of refractory stones, to

Rarely can buy a small half of the magnificent building.

But such a precious thing is placed in an inconspicuous 3,000-battalion outpost, without concealment.

In that case, don't.

I just picked it up if I didn't.

Zhou Li and Tang Guan, who were tacitly acquiescing, carried two pockets of refractory stones, and then Zhu Qianyun, who rushed over, also carried a pocket. In this way, Zhou Li and the three of them happily finished collecting wool and walked out of the warehouse.

"All ready?"

Putting the last package in the carriage, Cen Shu raised her head, looked at the three people who came out of the outpost, and said, "We're done here." ”

"Water, food, and some utensils, I took a lot of them."

patted the carriage box, Cen Shu sighed with emotion: "I didn't expect that there are so many redundant materials in the outpost of the 3,000 battalions, even if we take so much, it is only a drop in the bucket, no wonder they all say that the Northern Army is rich." ”

"It's normal for the army at the border pass to be a little richer, otherwise it's easy to make trouble."

Zhou Li took the bag of white sugar that Tang Guan handed him, and then habitually pulled Tang Guan over, paused up and down, and took out the other bag of white sugar she was carrying. Under the resentful gaze of the other party, Zhou Li put away the sugar and explained:

"The thirteen cities of the North Ring Road are border passes themselves, and the Han King made great contributions to the Battle of Jingjing, so Ming Chengzu gave him a lot of rights. The military fields, official merchants, and salt and iron monopolies of the thirteen cities of the North Ring Road were all given to the Han king, so the army under the Han king was much richer than most people thought. ”

Raising his head, he looked at the thirty armor soldiers who had changed into armor, each led three war horses and one maned horse, and was ready to attack day and night, Zhou Li squinted his eyes and whispered:

"But it's a little strange to be so rich."

"It's fine."

Zhu Qianyun also led a war horse, compared to the galloping horse that is good at foot strength in Taixue, this kind of war horse with armor is more suitable for her riding habits. The dark and shiny war horse was draped in wrought iron armor, with Zhu Qianyun's Tang knife on the left side of the horse, and a suit of armor hanging on the right side. She patted the horse's neck and said with some emotion:

"Over the years, my father has often done business with Hu merchants, and their rare herbs and gold and silver are extremely cheap, and sugar, salt and clay pots have been shipped in batches, and they have been exchanged in batches, and after a long time, my father has found that even if he does not have the so-called Jiangnan Water Town, he can be very rich, and he can also earn foreigners' money, and he is even happier."

"That's just as well."

Zhou Li nodded, but he also felt normal. After all, this world is a magical version of the Ming Dynasty, and those countries outside are even more magical. Ever since Joan of Arc told Zhou Li that Gandalf, the white-robed mage, was the first elder of the French Witch Church, he felt that he would not be surprised by what happened in this hairy world.

Unless Tang Guan awakens the blue silver entanglement.

Soon, thirty armor soldiers were waiting around the carriage, and the black and heavy armor was extremely oppressive, making Xu Teda's face even paler not far away. He didn't know why, a poor rat, could experience such a wonderful rat life in just three days. From being voluntarily sent to Taiying, to being kidnapped by the Black Hand Condor, and now he has inexplicably become a prisoner of the 3,000 camp, and he is going to be sent to Taiying to be beheaded.

Rat, rat, I'm really going to send it.

Compared with Xu Teda, who has already begun to consider whether he can change species next time he is reincarnated, his sister Xu Xuan is extremely calm. She took advantage of the moonlight to transform into a black cat, and she didn't care about the eyes of those armorers, and swaggered into Zhou Li's arms, looking around with golden eyes, looking at this outpost curiously.

"See something?"

Zhou Li turned over and got on the horse, not forgetting to put the black cat on his shoulder. Lowering his voice, Zhou Li asked in a low voice as if nothing had happened.

"There's a lot of line."

Doubts appeared in Jin Cancan's eyes, and the black cat tilted his head and replied softly: "There are many lines that I can't see clearly, they are entangled, and it is difficult to distinguish the source, and there is even a piece of pink red thread that I can't understand, which is still somewhat familiar." There are some lines that I have never seen before, and they don't look like Daming's lines. ”

"Sure enough."

Zhou Li narrowed his eyes, glanced back at the outpost, and then suppressed the doubts in his heart, and rode his horse to follow the carriage not far away.

Li Zuoying was placed in the outpost by Zhou Li and others, a sergeant was in charge of guarding, and the rest were responsible for escorting the "prisoners" and Zhou Li in the carriage.

As for Zhuge Qing...

"The Taoist is also fake?"

In the carriage, Cen Shu looked at Zhuge Qing, who had been silent, and asked in disbelief, "She is also a doppelganger?" ”

"Sort of."

Zhou Li thought for a while and said, "Su Xiuyi used willow branches to disguise two clones, one of which was herself, to confuse these armorers. The other is the unphased clone, which is her reward for us. The Taoist didn't know what to do, so he turned this phaseless clone into her form and handed it to me. ”

"No wonder the Taoist has been silent."

Yun Baibai nodded in a sudden realization, only then did he understand why the Dao Chief didn't say a word from beginning to end, and most importantly, the Dao Chief didn't even take out the Shadow Stone in the face of Fang Cai's great fun!

This is even more terrifying than Tang Guan's sudden lack of breathing. (End of chapter)
