The Northern Yuan Dynasty was just like a person who was ill and in great pain.

Chu Younan also followed.

The two men kicked open Bei Yuanzheng's door and were instantly shocked by the scene before them.

The room was in a mess, as if a fight had taken place. Bei Yuan was lying in a pool of blood, apparently seriously injured.

"Brother Bei, what happened?!" Su Bei hurried forward. After taking a look, she found that Bei Yuanzheng was not injured, but might have internal injuries. The blood around him was actually vomited by him.

"I...maybe I was poisoned..." Bei Yuanzheng said, spitting out another mouthful of blood, "You guys be careful..."

Before he could finish his words, a black shadow suddenly came in through the window, followed by several more black shadows.

Chu Younan did not show any martial arts along the way, and Bei Yuanzheng thought he was a scholar. It was only at this moment that he realized that Chu Younan's martial arts was not inferior to his.

There were so many black shadows, about a dozen in total. Not only did Chu Younan take action, but Su Bei also picked up Bei Yuanzheng's sword and fought with them.

Bei Yuanzheng was full of curiosity. The divine doctor and his wife were so skilled in martial arts, they must have hidden identities. Who were they? But his doubts only flashed through his mind. Before he could think about it, he saw two men in black walking towards Su Bei.

Without thinking too much, Bei Yuanzheng struggled to get up and rushed over.

His martial arts skills were better than Su Bei's, but he was poisoned, so his movements were a bit slow. Even so, he still blocked two swords for Su Bei.

The man in black is quite powerful.

Chu Younan saw that Bei Yuanzheng was injured and that someone was besieging Su Bei, so he hurriedly said, "Run!"

Bei Yuanzheng clutched his wound tightly, "You guys run, I'll cover your rear!"

He was almost dead, who could bear to let him stay behind? Chu Younan quickly grabbed him and let Su Bei run first.

Su Bei was still running very fast, but Chu Younan was good at Qinggong, so even with Bei Yuanzheng dragging her, she still caught up with her quickly.

The men in black were left far behind, and they finally got rid of them.

At this time, Bei Yuanzheng was already a little out of breath and looked like he was about to die.

Su Bei didn't care that his medical skills were not very good. If he wasn't treated, he would die, so he might as well give it a try.

She took Bei Yuanzheng's pulse, and this was a serious diagnosis. She found that Bei Yuanzheng was not suffering from poison, but probably from a Gu poison.

The reason why she said it was a rough estimate was because she only felt that its pulse was somewhat similar to Bei Yanming's, but not exactly the same, and she had no research on poison.

"The person who killed me was... was..." Bei Yuanzheng said while panting.

"Okay, okay, stop talking. You are seriously injured and need to recuperate." Su Bei quickly pressed on his wound.

One was in the shoulder and the other in the thigh. Both wounds were very deep and needed to be stopped immediately.

But Bei Yuanzheng was still struggling, "You...you have to be careful...they...they..."

"They want to kill us. They are the secret guards sent by the Queen of the Underworld." Chu Younan said in one breath, pressing the wound on his thigh.

His little Beibei can't just press this position.

Bei Yuanzheng was still struggling, "She...she didn't want to..."

"She doesn't want you to go back, nor does she want us to cure Bei Yanming. She wants to take this opportunity to support her young son to ascend the throne." Chu Younan finished speaking in one breath and pressed his sleep point.

I thought he was always talking about children, but I didn't expect that he was just a chatterbox...

"What should I do?" Su Bei was a little embarrassed, "He seems to have been poisoned, but I can only treat his external injuries..."

"Take him to Miaojiang. Xiao Han should give him face." Chu Younan did not hesitate. After all, Bei Yuanzheng had just blocked two knives for Su Bei. Putting aside Bei Yanming, he could be considered a friend.

His injuries were treated by Chu Younan. After years of marching, he was able to deal with external injuries, but the wounds were not sutured very nicely.

Perhaps he was a little jealous of Su Bei's cousin? In the last night raid, half of the Queen's men were killed and she even lost someone. She was very angry.

For this, she broke her favorite teacup.

"Has the poison been administered to him?" There was a fierce light in her eyes.

The secret guard nodded. "It was difficult to administer the poison. Several of my subordinates fought with him and then forced the poison into his ears. Then we killed the two doctors according to your order. I don't know why the eldest prince didn't die after being poisoned..."

"Useless!" The Queen of Hell smashed her beloved teapot in anger. "Who told you to put it in your ears? I clearly told you to put it next to Bei Yuanzheng's ears!"

The doctor said that as long as you put the insect next to a person's ear and then drop a few drops of blood in the bottle on the person, the insect will drill into the person's ear, and then within an incense stick of time, the person will explode and die.

In other words, just do it quietly.

But the Queen of Hell had no idea that when the leader of the secret guards opened the vial of blood, he found that the blood inside had already clotted and could not be poured out. What could he do? He even cut his own hand and dripped blood on Bei Yuanzheng, but it didn't work!

And the blood was not scarce yet. He accidentally cut too deep, and half of the blood around Bei Yuanzheng must be his.

He could only stuff the insect into Bei Yuanzheng's ear.

No matter how soundly Bei Yuanzheng was sleeping, he would definitely wake up if someone stuffed something into his ears, so a fight broke out.

During the fight, Bei Yuanzheng injured another secret guard, and that man shed a large pool of blood. So the blood that Su Bei saw him spit out was not just from Bei Yuanzheng alone.

At best, only one tenth...

To explain why the poisonous insect didn't work, we have to first talk about how the Queen of the Underworld got the poisonous insect.

After Lu Yu confirmed that Bei Yanming was poisoned by a Gu, Queen Ming was worried about the throne day and night, so she wanted to get some Gu worms to control the remaining princes so that she could leave the throne to her son.

But the poisonous insect is hard to come by, so she sent people to investigate openly and secretly. On the surface, they were looking for a famous doctor to treat Bei Yanming, but in fact they were looking for someone who understood the poison of poisonous insects.

As expected, hard work paid off. Her people really found one at a market on the border of Ukraine.

The man set up a stall to sell poisonous insects, saying that this one could make people explode, and that one could make people go crazy, and each one of them sounded amazing.

The Queen of the Underworld asked the secret guards to buy a total of twelve from him, ensuring that everyone except her son got one, to ensure fairness and justice.

The method of using the insect is very simple, just as the Queen of the Underworld said just now, Bei Yuanzheng is using the first one.

Maybe the secret guard was a little unskilled, or it could be a mistake.

The Queen of the Underworld thought so and sent someone to poison the Second Prince with a poisonous insect.

The secret guard returned after a while. After returning, he said with a bitter face: "Madam, the blood has coagulated again. This time...should we plug it?"
