Xiao Qiao’s carriage drove very fast, and did not take into account the feelings of her lady on the carriage, to the extent that she was very satisfied with Wu Zheng. He didn’t expect that this girl was still a racer who likes drag racing, but it’s a pity that if the carriage can have it. Give her a sports car, isn't this girl crazy
When he arrived at Yuzhou City, the moon had not yet reached the mid-sky. There were thousands of lights in the city. Wu Zheng knew that one of the thousands of lights was lit for himself. It was hung at the gate of his house as usual. The night breeze is blowing.
The carriage stopped in front of the city gate, because the city gate was closed, which made Xiao Qiao who rushed all the way feel a little disappointed.
"You should have a way to get into the city!" Wu Zheng said to Yin E on the carriage.
Yin E opened the curtain and looked at the closed city gate under the night. He turned around and shook his head at Wu Zheng and said with regret: "What can I do if the city gate is closed?"
Yin E looked regretful, but in Wu Zheng's eyes, she was clearly gloating at this moment.
"What are you going to do?" Yin E hurriedly asked when Wu Zheng got up and got out of the car.
Wu Zheng said: "Since you don't help, I can only figure out a solution by myself."
Yin E didn't rush when he heard it, and Wu Zheng, who was leaning on the door of the car and looking at the ground, smiled and said, "Is it possible that Young Master Wu, who is good at using tools, wants to cut wood and build a siege ladder here?"
Speaking of this, Wu Zheng remembered one thing, and asked: "You said that, I remembered one thing. The reason why the victims were so easy to break through the city gate at the time was rumored to be the gate of Yuzhou City for so long. It was caused by disrepair. But I went to check and found that someone poured aqua regia into the top door slot, turning all the original hard bluestone into tofu. Will you know that?"
"What aquamarine water, that is the Brahma holy water of this sect, why is the son interested in the holy water of my teaching?"
Wu Zheng smiled and said, "It's okay for you to bluff those who have never seen the world, and in front of me, there are some big swords in front of Guan Gongmen."
Yin E sneered: "Does the well-informed Young Master Wu also know the secret recipe for me to teach holy water?"
Wu Zheng shook his head and said: "It's not very clear, but as far as I know, this thing should be a combination of two kinds of acid. By the way, you might think that the acid I said is probably the same as the vinegar you drink. Kind of things. Let's put it this way! You should use salt and nitrate when preparing holy water!"
Xiao Qiao, who was sitting on the rafters, couldn't help but stared at Wu Zheng with his eyes wide open, and said to the young lady in her family: "Miss, didn't you say this is the secret of our teaching? But how does Young Master Wu know? "
Yin E gave her a sideways look: "I want you to talk more! No one will treat you as dumb if you don't speak."
Then he said to Wu Zheng: "Young Master Wu seems to be really knowledgeable!"
"Girl Yin E is absurdly praised. I just read a few more books. Although I know the method, I can't do it. After all, watching cooking is one thing, and doing it myself is another. But I want that kind of acid made with nitrate. I wonder if Girl Yin E can help me
"What do you want that thing for?"
"Just play around. By the way, there is an acid made from sulfur. I wonder if Miss Yin E will?"
"Sulfur?" Yin E thought for a moment but shook his head.
Wu Zheng said: "No, it doesn't matter. The method of preparation is probably to burn the sulfur and dissolve the rising smoke in water. However, the effect of the sulfuric acid produced by this method is not very satisfactory. But with Miss Yin E’s ability, I believe that this problem shouldn’t bother you. If you can produce sulfuric acid that satisfies me, Wu Zheng must be at a high price like you bought
Yin E said: "These are harmful things, what do you want to do with these things?"
Wu Zheng smiled and said, "harmful? This may be really harmful in your hands, but it can benefit the people in my hands."
"Those are highly toxic substances, how can you use them to benefit the people? I think you 80% think of some harm and want to harm others!"
"Do you think everyone is the same as you? Don't forget who my master is. He is a famous needle, scorpion, centipede, snake letter, gecko, toad, beetail needle, which are not poisonous, but these things When it comes to my master, which one is not a good medicine for curing diseases and saving people? It doesn't matter who is in the hands of whether it hurts or not."
"I can't tell you, since you want nitric acid and sulfuric acid, I'll try to get it for you! As for what the high price is enough... (End of this chapter)
