Impeachment will make me stronger, and I will be invincible on the road to death.

Chapter 19 The principle of acid-base neutralization

Once the money is raised, the showmanship will naturally come to an end.

Wu Zetian and the civil and military ministers receded like a tide, and Yang Yanzhang also got a moment of peace.

At this time, there were only some idle people living near Beishi around him, looking at him with flattery or awe, some because of his talent, some because of the fame he had gained in the past two days, and some because of his position. .

But he couldn't care about this.

He hadn't slept for two days, and now he was terribly sleepy.

Looking at the gold in his hand, Yang Yanzhang went to stay at an inn in Qinghuafang without saying a word.

The most prosperous place in Luoyang is the North City where dignitaries and dignitaries live together.

Looking at Beicheng, the neighborhoods closest to Shangyang Palace are the busiest.

Qinghuafang, where Yang Yanzhang lives, is one of the best.

This place is only one street away from Xuanren Gate of the Royal Palace.

In addition to the residences of royal relatives and court ladies, there are also some of the most luxurious inns, restaurants and other places in the Tang Dynasty.

The piece of gold Yang Yanzhang had was only enough to stay in the upper room for one night.

……

Unlike Yang Yanzhang who was already asleep, Wu Zetian had been deep in thought when she returned to court.

Beside her, Shangguan Wan'er's eyes flickered thoughtfully.

"Wan'er," Wu Zetian suddenly said after a long time, "do you know the meaning of the method Yang Yanzhang showed?"

Shangguan Wan'er shook her head: "Wan'er is thinking about this issue, but Shu Wan'er has little talent and knowledge, and she really can't figure out the reason behind it! Why doesn't the Queen Mother directly call him into the palace and ask him for a clear explanation?"

"Hmph, this little thief has been very proud these past two days. Today he showed off his talents in Bei City, attracting the admiration and admiration of all the ministers. If you ask him for advice, wouldn't it only further fuel his arrogance?"

Shangguan Wan'er lowered her head and thought for a moment, then her eyes lit up: "By the way, I heard that Di Renjie in the court is extremely smart and knowledgeable. Maybe he understands!"

"Di Renjie?" Wu Zetian's face became greener, "That guy who didn't know how to advance or retreat and read out my poems?"

"Exactly..."

"Hmph, I am planning to punish him for some crime, so just give him a chance! If he knows the truth, then I will not only let things go, but also reuse him! If he can't answer, then don't blame me. You're welcome! Go and send someone to announce him in!"

……

Di Renjie was at his house. He also picked a few morning glories and bought a carrot at a high price. He was studying Yang Yanzhang's magic skills hard.

"It's strange. I also dipped the morning glory in water and then poured carrot juice on it. Why can't the writing show on mine?"

"If it doesn't work once, then try a few more times! Fortunately, I only cut a small piece of carrot just now!"

So Di Renjie tried several more experiments in one go, but he failed to succeed until he ran out of carrots.

"What's going on? Why doesn't the same craftsmanship work for me?"

Di Renjie thought about the process of Yang Yanzhang's talent display several times, and felt that there was really nothing missing, so he fell into doubts.

"try again?"

"There's not enough money... This carrot is really ridiculously expensive, more expensive than gold and jade!"

In desperation, Di Renjie had to give up. "You have the nerve to ask Yang Yushi for advice? No! The Queen Mother has an ambiguous attitude towards him. If I get close to him, there is no guarantee that I will not be involved in some unexpected incidents in the future! I accidentally read the love poem that the Queen Mother wrote to him today. come out……"

But as a diligent and studious Di Renjie, now he encountered a problem that he couldn't figure out even if he tried to copy a cat or a tiger, which made him feel very uncomfortable.

But at this time, people from the palace arrived: "Di Renjie! The Queen Mother invites you!"

"It's over. Could it be that because I read that love poem, the Queen Mother became so angry that she wanted to kill me?"

With full of anxiety, Di Renjie was brought into the palace.

"Di Renjie! I heard that you are a smart man. I have something to test today."

"Please speak, Queen Mother."

Di Renjie suddenly felt a lot more relaxed: It turns out that the reason is not to question the crime, but to consider my intelligence!I'm good at this!
"Then I want to ask you, did you understand Yang Yanzhang's juggling today?"

"What? Juggling?" Di Renjie was stunned for a moment, and then he realized what Wu Zetian was talking about.

"This... I understand!" Di Renjie's voice was a little stiff.

"Oh? Great! Then tell me, why can some soup and water create such a strange scene?"

Di Renjie was immediately stunned: "No, Queen Mother, you may have misunderstood what I meant. When I said understand, I meant that I understood Yang Yushi's process, but I didn't say I understood the truth behind it!"

When Wu Zetian heard this, his face suddenly darkened: "Di Renjie, I am giving you an opportunity to make meritorious deeds. It seems that you cannot grasp it! In this case, please explain to me what you did in Bei City just now. How dare you read out my poem?"

Di Renjie's face turned bitter: "Queen Mother, that was my unintentional mistake! But if you give me one day, Queen Mother, I will definitely know what's inside!"

Wu Zetian thought about it and realized that it was more important to know the truth behind Yang Yanzhang's "juggling" than punishing Di Renjie.

"Then I'll give you one day! If you still can't give me a satisfactory answer tomorrow, I will demote you to Lingnan!"

Di Renjie shuddered and went straight to Bei City without hesitation after leaving the palace.

After asking passers-by, Di Renjie quickly found Yang Yanzhang's inn.

Although Yang Yanzhang was still asleep, Di Renjie did not dare to wake him up, so he thought carefully and waited in the inn.

By this time, it was in the evening when Yang Yanzhang woke up from urinating, and then he saw Di Renjie.

"Old Di? Oh no, Master Di! Why are you here? Let me go and relieve myself, and we'll talk about it when we come back!"

"Let's go together, I happen to be going too!"

The two of them relieved themselves together and started chatting at the same time.

"Yang Yushi's move today really opened everyone's eyes! Such a wonderful skill is really difficult for mortals to understand!"

Di Renjie said deliberately.

"Oh? Mr. Di doesn't understand this either?"

"Yang Yushi is joking. If I hadn't seen it with my own eyes, I wouldn't believe it! This is probably a magic trick from a fairy. How can I understand this?"

Yang Yanzhang immediately laughed: "What a magic trick! It's just the principle of acid-base neutralization. Morning glories turn red when exposed to acid and turn blue when exposed to alkali. As long as you pay attention, it's not difficult to find! I took white morning glories and dipped them in water. When you write, pour alkaline carrot juice on it, and the words you write will appear naturally.”

"Acid-base neutralization? What is that? Alkali?? What is that? How do you observe these things??"

Yang Yanzhang's explanation not only failed to solve Di Renjie's doubts, but also made Di Renjie look confused.
