Looking at her impulsive daughter, Madam Su felt a headache coming on. How could a mother be so unsteady? She was truly glad she had come along.

"Xiao Jin, thirty miles isn't far. Don't go. Just have Commander Liu and your elder brother bring the people back."

Aya also realized what was happening and chimed in, "Your Highness, it's not far. Commander Liu, Grand Tutor Su, and I will go together and bring him back quickly. The message from the messenger is that Master is seriously injured, but it doesn't say his life is in danger."

Su Ruojin was anxious and didn't notice that Aya's eyes were darting away.

In fact, the message from the Gu worms indicated that Master's life was in danger, but Aya didn't want Su Ruojin to take that risk, so she had to tell a lie.

"Your Highness, with Senior Ye here, Senior Fu will definitely be alright," Yanluo also advised.

Looking at everyone's worried eyes, Su Ruojin thought for a moment and realized that with her master there, it wouldn't necessarily be any better if she went.

"Alright, I'll wait for you here. Go quickly and come back quickly. If anything happens, send a signal."

"good."

Aya and her group left in a hurry. Su Ruojin had something on her mind and could no longer sleep, so she simply picked up a pen and wrote a letter to Xiao Yanchu.

Knowing Xiao Yanchu as she did, she was naturally uneasy after learning that she had come to Xiaoyue. So she wrote a letter to let him know she was safe and sound, and to comfort him in the letter.

After handing the letter to the guard, Su Ruojin picked up her book and started reading again.

About an hour and a half later, there was movement in the camp.

"Miss, the person is back," Yanluo said as she entered the tent.

Su Ruojin hurried out and saw her master carrying her fifth master into the camp. She quickly walked over.

"Master, what happened to Fifth Master?"

"Let's go inside and talk." Ye Xunzhi carried her into the tent, placed Fu Linglong on the bed, and then wiped the sweat from his forehead.

Fu Linglong lay on the bed with her eyes closed, her face ashen.

Before Ye Xunzhi could say anything, Su Ruojin stepped forward and took Fu Linglong's pulse, her eyes turning cold.

"Who poisoned Fifth Master?"

A bitter smile appeared on Ye Xunzhi's face. "Herself."

Su Ruojin was stunned. In that instant, she had already considered that her fifth master's poisoning might be the work of the Northern Li people, that he might have been poisoned by a strange Gu poison, or that he might have accidentally ingested some kind of poison. But she never thought that her fifth master had poisoned her.

Before Su Ruojin could ask anything else, Ye Xunzhi continued:

"Upon hearing that Bei Li had occupied Liuzhou, we rushed over to see if we could be of any help."

Upon arriving, we found the city heavily guarded, and we couldn't get in. Even if we did, it would probably be of little use.

There was no point in continuing this journey, so in the end, your fifth master and I chose to settle down in a nearby village and captured a mutant for research.

Your fifth master has been researching an antidote to deal with the Demon Gu King. The medicine she developed before could only stop people mutated by the Gu poison for a few breaths.

In addition, for those who have been poisoned by Gu but have not yet mutated, taking this medicine can delay the mutation process; other than that, it has no other use.

We tried countless ways to improve the drug, but all of them failed.

Finally, your fifth master had a sudden idea: to try fighting poison with poison. He would put the most toxic Gu worm she had refined into the body of a mutated human, so that the Gu worm and the offspring of the Demon Gu King would fight each other.

As a result, this most toxic Gu worm only lasted for the time it takes for an incense stick to burn before it was killed and absorbed by the Demon Gu King's offspring Gu.

Your fifth master suffered a backlash and was poisoned as a result.

The medicinal herbs here are limited. I've tried many methods, but in the end, I could only save her life; I couldn't wake her up.

The more potent the Gu worm, the more severe the backlash.

Fifth Master used the most poisonous Gu worm she had ever concocted. It was only thanks to First Master's timely treatment that she survived the backlash.

In that sense, it's as if Master Wu poisoned himself.

It seems that Master Wu had foreseen this outcome.

She tried it with the certainty of dying.
