Shen Shu was stunned, but he still obediently lifted the sleeve of his right hand and put his hand on the table.

Shi Qingqian went to look for the treacherous trace, this trace had become faint day by day before Shen Shu set out on the expedition, but when she looked down this time, it was a shocking blue-purple lightning pattern.

"W-How can this be?"

The lines on the pulse of Shen Shu's right hand were even deeper and longer than when Shi Qingqian first discovered it, and at this time there was already a tendency to spread towards the elbow. Shi Qing rolled up his sleeve and took a look, and sure enough, there was already an extremely thin trace that had climbed up half of Shen Shu's forearm.

It stands to reason that since Shen Shu stopped eating poisonous pastries and drank the antidote concocted by Shi Qingqian, the poison in his body should be slowly discharged.

In fact, the traces of those days became faint, which also showed that Shi Qingqian's medicine was useful. But why, it's only been a year, and there are more poisons in Shen Shu's body? Could it be that this poison could not regenerate on its own?

"Did you do what I told you to stop eating those poisonous pastries?" Shi Qingqian was a little anxious, and his tone unconsciously became a little harsh.

Shen Shu nodded, "Yes." ”

Shi Qing was stunned, and there was a nameless anger in his heart, "How can it be more serious?" ”

This anger is naturally born because of his own dereliction of duty and incompetence. However, although Shen Shu still had the poison uncleared before he set out on the expedition, as long as he no longer touched the poison primer, the poison remaining in his body would only find a place to hide in an orderly manner, how could it be like this?

At least, within the scope of Shi Qingqian's cognition, there is no poison that will increase more and more, after all, poison is not cancer cells.

"I don't know." Shen Shu's face was innocent, and Shi Qingqian's shadow was reflected in his eyes, "When I was in the Northern Desert, it had already begun to get bigger." ”

"Then why don't you tell me as soon as you get back!" Shi Qingqian blamed, Shen Shu actually watched this strange pattern grow all over his arm.

Shen Shu saw that Shi Qingqian was a little anxious, so he had no choice but to show a comforting smile, "I'm too busy, so I forgot." Anyway, this poison ...... It didn't help, and so far, it just made me feel weaker at times. ”

As soon as Shen Shu said this, Shi Qingqian was willing to calm down and think about it.

Yes, although this poison has always been in Shen Shu's body, she didn't notice the existence of this poison when she gave Shen Shu a pulse. Shen Shu's pulse was beating normally, and it seemed that this poison was still in a latent state so far.

But Shi Qingqian knew that this was definitely not a good thing, this poison had been dormant for several years, one might not be dead, and the other might be ...... There is also a lack of a key drug primer.

If the first case is okay, as long as you are always careful and do not ingest poisons. But if it is the second case, it will be too dangerous, because Shi Qingqian doesn't know what kind of poison this is, and there is no way to determine what kind of medicine it is.

"Alas......" Shi Qingqian sighed deeply, "No wonder your body is so weak, there were four people who entered the water yesterday, Shi Zhenxiang and I are fine, but you are sick because you practice martial arts every day." ”

"You don't have to worry so much," Shen Shu stretched out his hand and gently rubbed Shi Qingqian's broken hair, the touch of his fingertips entwined made him a little reluctant to withdraw his hand, "The person who poisoned me won't end my life so hastily." ”

Hearing this, Shi Qingqian was silent.

The Poisoner...... Isn't it the emperor Shen Lun? He clearly spoils Shen Shu, the more he wants to treat him like this. Poison, the so-called companion is like a tiger, presumably this is the truth.

But what Shen Shu said is not unreasonable, Shen Lun's use of medicine must have ulterior motives, if he wants to kill Shen Shu, with his status, isn't it easy.

Therefore, Shi Qingqian relieved himself a little, at least Shen Shu's life was worry-free now, and he could have a lot of time to find a way to help him.

"By the way, Shen Shu, I'll teach you a way." In order to allow Shen Shu to identify the poison in the drug, Shi Qingqian decided to teach him the method of identifying the poison, "You prepare some alum in the future, burn it with fire, or crush it into foam, if there is another inexplicable drug, drop one or two drops into the alum, if it changes color, it means that it is poisonous, and you must not drink it." ”

Previously, Shi Qingqian had only used silver needles to test poisons, but the principle of silver needles was to test the presence of sulfur substances, which did not work for some snake venom and some poisonous weeds.

It was convenient for Shen Shu to ask for anything here, so she asked him to use a more effective method.

Seeing him nodded, Shi Qingqian was relieved, "The medicine and pastries that the emperor gave you are still sent every day?" ”

"Send," Shen Shu nodded, "But I only drank medicine, not pastries." ”

Shi Qingqian always felt uneasy, she really didn't understand why this poison was getting worse instead, so she asked again: "Shen Shu, the next time you drink medicine, remember to use the method I taught you." ”

"Don't worry, how dare I not listen to what I said?"

Looking at the relaxed smile on Shen Shu's face, Shi Qingqian really didn't know who was poisoned, and why he was even more panicked than the poisoner himself.

Shen Shu's thin lips smiled, and then they turned into a pale red line, and his smile was gentle like water, making people feel as if they were bathed in the sun.

Shi Qingqian couldn't resist the most, it was Shen Shu who was smiling, she could only care about shouting in her heart: Please stop exuding charm, okay!

"Uh...... That, ah! Shi Qingqian hurriedly changed the subject, "Shen Shu, give me a little of your blood." ”

"My blood?" Shen Shu said suspiciously, "Okay." ”

Shen Shu didn't ask what he was going to do with it, Shi Qingqian was still a little moved and embarrassed, "You don't even ask why?" I'm not afraid that I'll harm you with your blood. ”

"Huh? So, is the child trying to harm me? Shen Shu heard this and deliberately quipped.

"Of course not!" Shi Qingqian smiled and said, "I want to take your blood back, maybe I can find out what kind of poison you have been poisoned." ”

Shen Shu nodded, and got up to find the container for the blood.

He didn't ask, not because he wasn't afraid, but because he firmly believed that Shi Qingqian would not harm himself. He still has this trust.

Soon, Shen Shu brought a small bottle of white marble and generously handed it into Shi Qingqian's hand.

Shi Qingqian came to Yanwangfu today to see a doctor for Shen Shu, so he specially brought a pack of silver needles for acupuncture, but he didn't expect it to really come in handy.

The slender needle pierced into the blue and purple lines on Shen Shu's wrist, and the blood that flowed out turned out to be in a state of bruising. Shi Qingqian was not surprised, it was very common for the blood to be abnormal after poisoning.

As Shi Qingqian squeezed his hand, the color of the blood that flowed out became more and more red. It seems that the poison has not yet spread throughout the body.

After a while, Shen Shu's blood was filled with a small half bottle, and Shi Qingqian stopped the movement in his hand, stretched out his hand to exert force, and pressed the bleeding place.

The silver needle was pierced diagonally, and she pressed it in the direction in which it was inserted, not only did it not touch the wound, but it also stopped the bleeding.

"Guy, is it enough, it's not enough." Shen Shu looked serious, but he made Shi Qingqian laugh.

"Do you really think I'm going to draw talismans with human blood? That's enough blood. Shi Qingqian scolded with a smile.

Shen Shu is really upright and cute, how can anyone ask if the blood is enough, and if there is not enough, there is still one?

"Knock Knock"

"Lord Wang, have you run out of medicinal food?"

When he was packing up the silver needle, suddenly Yu Ling, who had been waiting for a long time, knocked on the door, and the voice was sudden, Shi Qingqian was clever and actually stabbed the needle into his finger.

The blood immediately flowed out, and Shen Shu's face turned cold, "Wait!" ”

But the movements of the hands are still gentle. He picked up Shi Qingqian's fingers, put them directly into his mouth without thinking about it, and used the tip of his tongue to lick the blood that seeped out.
