Hearing Yang Asha's reply, Wu Weiyi only thought that the misunderstanding between her and Mo Zhai had been resolved, and he was naturally overjoyed. He bowed to her again:

"Miss Asha is so reasonable, and the most commendable thing is that the girl has a benevolent heart...... Wu Weiyi thanked Miss Asha in advance! ……”

Bestowed such praise on an outsider, Yang Asha was a little embarrassed by what Wu Weiyi said. couldn't help but make her feel a little embarrassed:

"Huh! …… Ok ok! It's okay! …… You guys...... You don't have to take it too seriously......"

Then, I saw that Wu Weiyi had resigned from Yang Asha, and turned around and was about to turn back. At this moment, he heard Yang Asha call him again:

"Hey!"

Wu Weiyi heard Yang Asha's call behind him, and immediately stopped. However, before he could turn back, Yang Asha was very concerned about his back and asked:

"You...... You can really keep my father and my mother...... And are our people safe and sound? ”

Wu Weiyi heard this question, but he didn't know how to answer her. Thinking that he Wu Weiyi was dressed back in the Spring and Autumn Period, and after falling into Shudi, what was there that he could really grasp accurately? If it weren't for the strength of everyone along the way, he Wu Weiyi would not have said that he would have made a fortune here, and he might have died at this moment, and he would have perished in the world.

However, Wu Weiyi also knows that at this critical time of survival, if

If Wu Weiyi told Yang Asha that he was also invincible, if this word reached the ears of her mother and father, I am afraid that it would only shake the morale of the army, and there would be no harm but no benefit!

Therefore, after thinking about it, Wu Weiyi had to turn his back and say perfunctorily with Yang Asha:

"Huh! …… Girl, relax your heart, Weiyi must go all out! ……”

In fact, although Wu Weiyi said this, he was not true in his heart. Therefore, I saw that Wu Weiyi had just landed on the ground, lest Nayang Asha continue to ask questions, or leave alone without looking back......

……

It has been a few days since these servants listened to the advice of Ke Erzhenxi and Wu Weiyi, abandoned their own Dazhai and guarded the back mountain.

In the past few days, the servants guarding the back mountain have not been idle for a moment. First, a lot of bamboo was cut down on the back mountain, and simple houses were erected for living in people.

Then, Wu Weiyi also made a statement, and transferred a considerable part of the manpower, so that he set up many mechanisms on the way into the mountain with Mo Zhai, in case the bandits under the mountain took the opportunity to touch the mountain.

Not only that, but it also caused them to search the mountains for all kinds of fire-starters, such as charcoal and bamboo charcoal that had not yet burned out in the previous fire......

One day, I saw some servants who had been sent out, and I don't know where they found a strange stone from the mountains! I saw that these stones were all covered with a layer of light white hair! And some of these white hairs are mixed with a little red.

It turned out that those servants knew that Wu Weiyi was now using fire to defeat the enemy, so they offered advice there one after another, and even brought all kinds of rare monsters to Wu Weiyi.

But Wu Weiyi couldn't understand what they were saying, so he had to keep Ke Erzhenxi by his side and interpret for him...... I only heard that Ke Erzhenxi was holding these stones on the one hand, and on the other hand, he was quite puzzled by Wu Weiyi's interpretation:

"These long-haired white stones that these people are bringing you now, they call them 'Zhu Rongshi'! According to these servants, these unsightly white hair stones are still Zhu Rong's leakage! …… And...... These excrements are all stones that can ignite fire! …… Ben Hao has never seen it, and he doesn't know whether it's true or not......"

After hearing this, Wu Weiyi took those white-haired stones from Ke Erzhenxi's hand and looked at them carefully...... It turns out that the "white hair" on these white hair stones is actually not really white hair on the stone at all, nor is it some wild mushrooms in the mountains, but a crystallized salt frost!

After Wu Weiyi took the salt frost down, he rubbed it in the palm of his hand, but he could still feel a chill in it.

"Wow! …… These hoarfrost are still so frozen, as if they are holding ice! ”

Ke Zhenxi listened to it, but he only felt that this Wu Weiyi was rare and strange:

"You're making too much of a fuss! These hoarfrosts in your hands are called summer frosts to us! In the middle of summer, where we Qiang people graze cattle and sheep, we can see these 'summer frosts' everywhere. These summer creams can be combined with water to melt them, and they are slightly cool to hold, and it seems that our witch doctors will also use them for medicinal purposes......"

Wu Weiyi listened to it, and then thought again:

"According to what Kerzhenxi said, this thing ...... It's like ......."

So, Wu Weiyi immediately found someone to get a pot of fire pit, and threw one of the white hair stones into the fire pit.

At this moment, I saw that the white-haired stone was actually bursting out of a burst of dark purple flames in an instant! Seeing this, Wu Weiyi couldn't help but stand up and shout:

"Potassium nitrate!"

Ke Er Zhenxi was also taken aback by his sudden uprightness, seeing that Wu Weiyi was so excited, and hearing that he was inexplicably calling out something, but he didn't know what it was about...... Ke Zhenxi couldn't help but ask curiously:

"Nitrate...... What the?! …… What are you talking about?! ”

Wu Weiyi knew that they definitely didn't know anything about "potassium nitrate", and they probably hadn't even heard of "saltpeter". So, he paced back and forth a few steps, and said to him again:

"Oh...... I have lost my tongue, I already know this thing, this is the 'frost of the earth'! ”

"Huh?! …… You! …… You've been holding back for so long, and you're holding back such a name? …… Frost that grows on the ground in summer...... You call it 'ground frost', Ben Hao calls it 'summer frost', so over and over again, but isn't it still the same object?! ”

When Ke Er Zhenxi heard this, he couldn't help but be dizzy by this Wu Weiyi...... How could he have thought that this Wu Weiyi had already made a plan in his heart at this time, and this "ground frost" was the magic weapon for this calculation! …… And Wu Weiyi obviously didn't want to talk to him here at this time, so he just told him again:

"Brother Cole...... Go and find Mo Zhai, Weiyi and him have important matters to discuss now! ”

When Ke Erzhenxi heard Wu Weiyi's dispatch, he naturally seemed extremely unhappy:

"But why do you look down on Ben Hao so much? …… Ben Hao's courage and fame are resounding all over the world, and he can also speak four languages, but what can't he discuss with Ben Hao? Do you have to go to that black-faced imp?! ”

Hearing Ke Zhenxi's complaint, Wu Weiyi only felt angry and funny, and couldn't help but walk up and pat him on the shoulder and arm:

"Huh...... The Cole brothers really misunderstood! …… The so-called art industry has a specialization! …… If you talk about the strength of this body's brave arms and the ability to interpret the words of the Quartet, Weiyi and Zhai are not as good as brothers! However, if it comes to exquisite craftsmanship and skillful organs, then Weiyi and his brother are not as good as Zhai! …… What's more, as the saying goes, 'learn from each other's strengths and complement each other', if you ask your brother to do it, wouldn't it be like cooking chicken with a cow's ding, and it's overkill? ”

Just listening to this Wu Weiyi's words, not only did he understand the truth, but he also imperceptibly boasted about him Ke Erzhenxi to Meimei...... And these words of praise also made him extremely useful in his heart.

So, this Ke Erzhenxi laughed loudly, so he didn't say a word, temporarily resigned Wu Weiyi and went outside to summon Na Mo Zhai to discuss the matter......
