Regarding Cui Yan's plan, Shopkeeper Wu also had a faint guess in his heart.

Cui Yan is a doctor, and if she knows how to heal, she will be poisoned!

In the battle outside Ping'an Town, although he did not participate, he also heard that thanks to the poisonous mist created by Cui Yan, they were able to fight against the elite of the Cui family with one-twelfth of their troops, and won the medicinal materials without anyone being injured.

has the credit of saving the people, even if Cui Haoran can't take the opportunity to be the emperor, Xiao Yu wants to kill him, he must take into account his reputation and consider the feelings of the people. Unless, Xiao Yu doesn't care about his reputation at all and wants to be a brutal and unkind tyrant.

It can be said that those medicines are Cui Haoran's hole cards to save his life, and the manpower arranged by the Cui family there can be imagined - even if it is not as good as the killer of Shuramen, it will never be weaker.

Without Cui Yan, they would have been able to succeed, but it would never have been so easy.

At this time, Cui Yan had already filled two pages, dried them and handed them to the shopkeeper Wu, "Looking for someone to buy the things on this, the more the better." ”

Shopkeeper Wu said in his heart, sure enough.

Xiao Yu's plan, he didn't know. However, Xiao Changyin's army was already approaching the capital, and the shopkeeper Wu thought that Xiao Yu should leave the capital temporarily. No matter who enters Liangzhou, Xiao Yu's journey must be full of crises, and with these things prepared by Cui Yan, he will definitely be able to provide a little more protection.

Shopkeeper Wu understands very well what it means to be a little more secure at a critical time. Survival, turnaround, and more......

Cui Yan said, "The first piece of paper is mostly poisonous materials, and you have to be very careful when purchasing, transporting, and preserving, and it is best not to contact the skin directly." The contents of the second piece of paper may cause an explosion, so be sure to avoid fire during storage and transportation. Otherwise, the consequences will be unimaginable. ”

In the past, she had read the news of the explosion of the fireworks factory in the newspapers.

As for the antidote? Cui Yan didn't think about it so much, poison is definitely used on the enemy. The antidote must also be prepared, but one point is sufficient, there is no need to prepare the amount corresponding to the poison at all.

Shopkeeper Wu's brows furrowed, he is not a doctor, and he knows that there is this medicine at most on the first piece of paper, and he doesn't understand the specific use at all. However, he knows everything on the second piece of paper. Isn't this the raw material used in alchemy and fireworks?

"Ma'am, this may be a little difficult." The shopkeeper pointed to the second piece of paper, not that he was stingy, but that there were a lot of people staring at this place in Danyang County. "There are many uses of medicinal materials, not only big families, but also ordinary people occasionally buy them, and we can send people to buy them in batches and times. However, sulfur and saltpeter are not commonly used, and if we collect them on a large scale, they will definitely attract the attention of those who are interested. ”

Moreover, just like Cui Yan was worried about, this thing is explosive, and no matter how much they buy, they can't stop other people's fire.

Cui Yan lowered her eyebrows, and what Shopkeeper Wu said was also true.

It may take a bit of thought to make lethal thunderbolts and bombs, but ordinary earthen cannons can be improved on the basis of fireworks. As long as you have the heart, you can definitely get it out. These arrangements she made, don't fail to become Xiao Yu's help at that time, but instead add resistance to him, then the gains outweigh the losses.

Cui Yan stretched out his hand and tapped on the table a few times, making a rhythmic percussion sound, and the breathing of the shopkeeper Wu and the shopkeeper unconsciously kept up with Cui Yan's rhythm.
