After Ke Er Zhenxi had not been running out for long, he saw that he led Mo Zhai over and rushed over with dust. After seeing Wu Weiyi, Mo Zhai immediately asked him:

"Zhai heard that Brother Ke Er had just called me, and said that he was the eldest brother who had something to discuss with me?... but he didn't know what was going on?"

Wu Weiyi saw that Mo Di entered the tent, and the corner of his mouth raised slightly, and said to him very excitedly:

"My brother, can you recognize this thing?"

When Mo Zhai heard Wu Weiyi say this, he looked at Wu Weiyi's hand and saw that Wu Weiyi was holding a white stone in his hand.

When Mo Zhai took the stone over again, he felt that the stone was filled with a hint of chill. Mo Zhai looked carefully and shook his head and said:

"This thing... Zhai has never seen it before... nor do he know what it is?"

Seeing that Mo Di didn't understand his intention, Wu Weiyi didn't tell him clearly. He just took another piece from the bamboo basket, and threw it into the fire pit without saying a word.

Just like the white-haired stone just now, I saw it enter the brazier and suddenly a deep purple fireworks rushed upwards!

"Wow?! This... this stone... can actually help burn?... It's really amazing!"

Wu Weiyi was amazed when he heard Mo Zhai watching from the side, but he was not in a hurry to explain to him, just called him to get some water.

Although Mo Zhai didn't know what Wu Weiyi was trying to get water, he didn't dare to neglect it after all. He immediately took out the tent and used a copper bowl to get a basin of water for him.

At the same time, when Wu Weiyi saw that the water came, he took out a piece of white-haired stone with a thick layer of "ground frost" from the basket. He soaked it in the basin of water! Suddenly, the thick layer of "white hair" was melted away by the basin of water in an instant!... Then only the bare blue-gray stone was exposed.

Moreover, those "white hairs" not only melted into the water in an instant, but even Mo Zhai's palms, which were originally holding a copper bowl, suddenly started to freeze!

"It's so cold and cold... These 'white hair'! Are these frost and snow?! But... But now the climate is warm, why don't these snow frost transform into water?... This... is really strange! And what's even more strange is... According to the principle, snow frost is water and colder than water. The so-called 'water and fire are hard to withstand', there is no such principle of frost and snow to help burn?!"

At this time, Wu Weiyi heard that Mo Zhai was there and was inferring it. Although he could not tell the difference between the Chou and Yin and Mao, he had already touched the characteristics of the "Ground Frost"... He heard Wu Weiyi smiled slightly and answered to him again:

"Your brother should not be surprised. This thing is not ordinary 'snow frost', but ground frost! Also known as 'nitrite soil'!..."

Mo Zhai was still at a loss when he heard this name. After all, he had never seen these new things since he was a child... Mo Zhai shook his head without knowing anything, and Wu Weiyi continued to explain to him:

"As my brother saw just now, this kind of nitrile soil can not only dissolve water and treat ice, but also promote fire!... Therefore, if it is used to make the fire, it will be the best thing!"

When Mo Zhai heard the word "Store Fire", he instantly understood Wu Weiyi's current plan:

"So that's it... Zhai can understand. According to the elder brother's previous intention, he originally planned to control the fire and retreat the enemy. However, the elder brother is now suffering from the fact that this place is not as good as Picheng, but there is no strong turbulence available... Therefore, the elder brother now wants to use this nitrate soil to make fire again?"

After hearing this, Wu Weiyi smiled slightly again and waved his hand to Mo Di and replied:

"Hehe... I'm just half right!... As I said, this time is not like using fire at the foot of Qingcheng Mountain in the previous season. I got the help of a strong ignition cabinet, so we were lying on the mountain roads on both sides and setting fires in the distance!... However, now we are all trapped here, and the slope here is relatively slow. The so-called "fire-like flame" is, if we are lying on the mountain, we will not only be unable to hurt the enemy, but also will not be equivalent to setting fire to ourselves?"

When Mo Zhai heard this, he felt that his elder brother was very sensible, so he immediately asked:

"What my brother said is very!... In terms of fire, setting fire here is no different from burning your own house!... Since that's the case, I wonder what method my brother thought of?"

Wu Weiyi pointed to the basket of "nitroso" again, and said in a very strange way:

"Haha!... Although my brother intended to use fire to defend the enemy a few days ago, he had been suffering for a long time!... However, now that we have these 'nitro earth', it makes me suddenly understand!... And my success or failure will be all about this thing!"

When Mo Zhai heard that Wu Weiyi was saying this thing so magical, but he didn't know where it was "strange"? So he couldn't help but ask:

"Suppose Zhai Yulun... Although this thing is quite unique, in Zhai's opinion, it is just something that attracts fire and aids the ignition, and isn't that novel?"

Wu Weiyi knew that Mo Zhai still didn't understand the truth now, so he asked him:

"Haha... Please imagine, if the thief attacked, and I want to send someone to set fire behind the enemy, what should I do?"

When Mo Zhai heard this plan, he was shocked:

"This!...How can this happen?...If we want to set fire behind the enemy, we must be in advance. But if we want to hide behind the enemy, we must not carry it with open fire. However, it will take more trouble to make fire by not carrying open fire, but only using fright to make fire by fist. We will definitely not be able to launch a forest fire in a short time!...If we really do this, we will not wait for the forest fire to become a force, we are afraid that we will all have to destroy it first!"

Wu Weiyi heard Mo Zhai's words and couldn't help but nod and said yes:

"Well... what I said is indeed extremely reasonable!... It is no different from what I thought about before!... However, now with this 'nitro earth', this plan will be successful!... As I said just now, the key to this plan is to attract fire!... If you can make something with this, you can use the fire anytime and anywhere... What do you think?"

When Mo Zhai heard this, he was shocked again and hurriedly asked:

"This... there is such a magical thing in this world?...If you get this magical thing, then the strategy you just mentioned is to try it out!"

At this time, Wu Weiyi brought the bamboo basket filled with a basket of nitrate soil and handed it over to Mo Zhai, and told him:

"Now there are many collected charcoals outside the tent. My dear brother sent someone to cut them into pieces, then bake them on yin fire until they are refined into ink! ... And my dear brother immediately went to find Ke Yeyi, and asked him to be the one who led the way here to learn the way. Here he would pick many such nitro earth stones... My dear brother only needs to pour the frost in the water as before, first pour it into water to make nitro water. Then mix the nitro water with the charcoal, let it sit for a night, and then put it in the open fire tomorrow, and then fill it in the bamboo tube, and then you can complete it!"

Although he knew nothing about the principle of this object, Mo Zhai was also a powerful person to remember. Even though he kept all these production steps in his mind... After Wu Weiyi explained the method of making this object, Mo Zhai nodded to him and said:

"Brother, don't worry, Mo Zhai has recorded it... Since that's the case, if nothing else, Zhai will go outside to prepare!...I will refine this thing tomorrow and report it to Brother Yu to know!"

After Mo Zhai said this, he bowed and bowed to Wu Weiyi. He then carried the basket of nitro soil in both hands and walked out of the tent!
Chapter completed!
