No. 521 recovered the weak radiation that accidentally leaked from the palace one by one.

Under the precise control of No. 521, the radiation was gradually controlled in the same area and fixed on the existing thirty light spots.

This massive project consumed a great deal of No. 521's energy.

The next step is to adjust the observation time, which can be fully automatically managed.

No. 521 was too lazy to move, so he simply asked No. 2321 to broadcast Wu Qing's live performance.

"What about now? Is your host still praising Prince Ding?" it asked.

"I bumped into it." No. 2321 replied briefly.

...hit?

No. 521, who is a member of the sweet pet system, is extremely sensitive to this word.

This word, in its vocabulary, means many sweet, heart-warming moments.

No. 521 was in high spirits, like a hound that had smelled fresh food.

It kept asking, "What happened? Who did you bump into? Tell me quickly."

No. 2321 paused for a second: "...No, I mean, it was hit in the physical sense."

"Prince Ding, he knocked his head against the table."

…

Just after Wu Qing finished explaining his speculation about Yushan, Prince Ding suddenly groaned.

The other three were attracted by the sudden sound and turned their heads one after another.

Prince Ding looked pale, with cold sweat oozing from his forehead.

He raised his bloody left hand, and a trace of confusion flashed in his eyes.

——A shocking hole was pierced in the left hand, and blood was gushing out from the bottom of the hole like a spring gushing out from the ground, dyeing the entire palm red.

"Eighth Uncle! You are bleeding!" the second prince exclaimed.

Wu Qing was also confused.

She was just giving the princes a shot of prevention.

According to the original plot, Prince Ding has not yet hidden his army in the belly of Yushan. Calculating the time, it will take at least five or six years.

Why did Prince Ding react so strongly and even bleed?

She seemed to be aware of something and lowered her head slightly, her eyes focused on the edge of the drawing table.

——The culprit was a slightly rusty iron nail.

It is about half a finger wide, slightly dark red in color, and twisted and irregular in shape.

Prince Ding had just rested his hands on the edge of the drawing table.

Perhaps because the studio had not been used for a long time, or perhaps due to negligence of the staff of the Imperial Household Department, the iron nail had loosened from the edge of the table and suddenly protruded several centimeters from the flat surface.

At this moment, the top of the sharp iron nail was already stained with a thrilling scarlet.

A few drops of blood quietly flowed down the edge of the drawing table, quickly soaking the ground and splashing blood.

The eldest prince was also startled by the glaring blood color on the edge of the table.

Doesn’t Uncle Ba feel any pain?

The iron nail had been driven into such a deep position, but Uncle Ba seemed to be unconscious, with a blank expression on his face and no sound.

Prince Ding stared at his left hand with a shifted gaze, as if trapped by some indescribable emotion.

The eldest prince called out to him, "Eighth Uncle? Eighth Uncle?"

Prince Ding was still in a daze, immersed in his own world and oblivious to what was happening around him.

It looked like he was frightened by the blood on his hands.

"…Prince, the wound is too deep. Let the imperial physician examine you carefully."

Wu Qing couldn't bear it anymore and tried to persuade him.

Prince Ding was nominally a substitute teacher, but in reality he was a prince.

She couldn't let anything happen to him in class.

What happened yesterday could still be considered an accident, but today Prince Ding was obviously injured by the tools in the studio.

The one injured today is Prince Ding, so tomorrow the ones injured may be the eldest prince or the second prince.

If someone were to make a fuss about this, it would be a huge blow to her class.

Before Prince Ding could refuse, Wu Qing continued:

"Your Highness, I was the one who accompanied you to the Imperial Hospital yesterday. If you go again today, the palace people won't be surprised if they see you."

The eldest prince and the second prince also echoed each other. They looked at Prince Ding's bloody hands and were filled with worry.

"Uncle Eight, your injuries are indeed serious. Let the imperial physician take a look."

Prince Ding came back to his senses, frowned and forced a smile: "Your Highnesses, don't worry, the wound is not too deep. I can bandage it myself when I get back."

The second prince persuaded again: "Eighth Uncle, you don't need to worry about us. Your injury is important, we will study on our own."

Prince Ding shook his head: "Really, no need, I just got hit by a nail by accident, it's nothing serious."

[That's not necessarily true.]

Wu Qing thought silently, "It's so deep, and the nail is rusty, I won't get tetanus, will I?"

After hearing this, the eldest prince hurriedly asked Wu Qing: "My dear, is Eighth Uncle really okay?"

He continued, "My mother once said that you are proficient in medicine. Can you check on my eighth uncle first?"

...Yes, the Queen also arranged this character for her.

Wu Qing suddenly felt that this character setting was quite convenient.

So she cleared her throat and said seriously: "Your Highness, don't underestimate this wound. The iron nail is so deep that it will form an anaerobic environment and accelerate the reproduction of tetanus bacteria..."

The three of them were confused by the subconscious modern words.

Wu Qing immediately adjusted his words.

"To put it simply, when a metal weapon injures the skin and flesh, it is easy for evil wind to invade, leading to muscle paralysis. In severe cases, it can even be fatal."

So serious?!

The eldest prince and the second prince both changed their expressions.

"Uncle Ba, you'd better go quickly."

"Yes, Uncle Ba, this sounds too dangerous. You must not take it lightly."

Wu Qing rubbed her hands together: "My Lord, if you are in too much pain, I can carry you over today..."

Prince Ding had no choice but to agree.

If he didn't agree, he was really afraid that Concubine Ji would take him away without saying a word.

He sighed deeply, his face showing an apology that was hard to conceal, expressing his regret for not being able to continue teaching.

Wu Qing said: "What's the big deal? It would be a shame if the prince's hand was left with a scar because of this."

The eldest prince and the second prince turned to look at her.

What's the meaning?

Wu Qing looked back and asked innocently, "Why are you looking at me? Am I wrong? You don't want scars on your hands, do you?"

The princes looked at each other, and all felt that Wu Qing's words were a bit strange, but they couldn't explain why.

Wu Qing nodded and said, "Then it will be the same as yesterday. I will take the prince to the Imperial Hospital, and you guys can continue to study."

"I've prepared the test papers, don't be lazy tonight."

When they heard the word "small test", the princes' shoulders slumped and they were not very willing to face it.

When they reached the door, Wu Qing turned back and reminded them, "Please keep the map of Yushan safe!"

"Yesterday, the Queen specifically mentioned that the Emperor is extremely concerned about your recent progress in study."

"Please improve this picture and hand it in when the time comes." Wu Qing continued, with a hint of encouragement in his tone, "I'm leaving now. Bye!"

After saying this, she did not give the princes any chance to refute. She decisively took Prince Ding's wrist and left the studio with him.

A gust of cold wind blew in Prince Ding's face, waking him up.

"Sir, we..." He opened his mouth slightly.

Do you really want to go?

Wu Qing's face was full of joy: "I remember that Dean Liu is on duty today, let's go."
