It has the same shape as ordinary iron stick yam, but the inside is red instead of white.

The medicinal effect is relatively direct. After taking it, it can directly enhance the Qi in the body and is mainly used for promotion.

Although it is only a fourth-grade item, it is more precious than the ninth and ninth-grade items.

Because so many people have advanced, it is difficult to break through on your own, so you need to step on the accelerator at this time.

Blood yam plays this role.

Of course, promotion was no pressure for Xu Mu. He only needed to have enough cultivation value to break through.

"Well, I'll give you a favor and exchange the blood yam for your life."

Xu Mu said to Xiao Ran, "Wait here for a while, I'll get you some medicine."

After saying that, Xu Mu left. Xiao Ran immediately took off his clothes and just lay there.

After lying down for nearly half an hour, Xu Muxin returned.

At this time, a black pill appeared in his hand, as big as a ping-pong ball.

There are a lot of grass roots on it, which look like cow dung.

Xu Mu came to Xiao Ran, took out the silver needles he had just bought, and began to stimulate the acupuncture points on the wound.

He has completely mastered where the acupuncture points are.

After two injections, Xiao Ran felt a burning sensation near the wound.

"What I have to do now is to draw out the opponent's strength, otherwise you will never be able to defeat him."

Xu Mu felt that it was almost time and pulled out a silver needle.

After a while, a thin stream of blood spurted out from the wound like a needle.

As time went by, the force of the blood spraying weakened, and finally it began to overflow.

The same method is used for other silver needles.

"Yes, the pressure in my body has dissipated. Eat this."

Xu Mu handed the pill to Xiao Ran.

"What is this big thing?" Xiao Ran frowned with some disgust.

"You should be thankful, there are seventh-grade medicines in here." Xu Mu said and turned to leave.

Xiao Ran had no choice. He had already come this far and couldn't help but trust Xu Mu.

She opened her mouth and swallowed the pill in several gulps.

After eating, she just tidied her clothes when she felt sleepy and finally fell asleep here.

…

Xu Mu and Ye Tong and Ye Yu were having dinner.

The two sisters are discussing where to go for fun tomorrow.

Xu Mu was thinking about other things in his mind. The reason why he wanted the rare treasures was actually because he wanted to upgrade Xu Ningbing to an ancient warrior.

The Dragon King is coming back soon. According to the plot, it was the Dragon King who allowed Xu Ningbing to become an ancient warrior, for which she is very grateful.

Xu Mu wanted to rush to the Dragon King and let her become an ancient warrior.

Although she was not his biological sister, Xu Mu could not bear to see her become the Dragon King's concubine.

Since he has not stepped into the natural treasures of ancient warriors, he can only use the power of destiny.

Anyway, I have gained a lot now.

After dinner, Ye Tong and Ye Yu were still discussing where to go, while Xu Mu was sitting on the sofa, flipping through his phone.

The door to the side suddenly opened, and Xiao Ran walked out. She came to Xu Mu and asked in a deep voice, "Does that pill contain sleeping pills?"

"It does help you sleep better. You probably haven't slept so soundly in a long time."

Xu Mu glanced at Xiao Ran, "You don't think I'll do anything to you while you're sleeping, do you?"

"I……"

Xiao Ran looked at Ye Tong and Ye Yu beside him, then shook his head.

"How do you feel? If you think it's effective, remember to give me the blood yam." Xu Mu continued.

"My injuries..."

Xiao Ran took a few deep breaths and found that the pain in his chest was really gone.

Before she knew it, she would be in great pain and would cough violently.

Who exactly is this Xu Mu?

I thought he was joking just now, but now it seems that maybe he really used a seventh-grade treasure on himself.

So how should I repay this favor?
