Xiao Yuchen's clenched hands trembled slightly, his thin lips were pursed into a straight line, and cold sweat was dripping down from the corners of his forehead on his pale face.

Can't go on like this......

Feng Qian's face was full of worry, and his heart was nervous: there was still a third of the spirit crystal, and even if Xiao Yuchen's spiritual power was overdrawn to the limit, it would be impossible to complete the remaining formation. However, it is obviously impossible to make him give up now.

What to do......

Feng Qianyan racked his brains to think of countermeasures, but he didn't have a clue at all: it would be nice if there was a way to replenish his mental power!

"Xiao Jiu!" Feng Qianyan hurriedly called out in his divine sense.

"The host...... Ha-" Xiao Jiu replied with a yawn.

"Can spiritual power be transmitted to other people?"

"Hmm, mental power......" Xiao Jiu thought about it and replied a little hesitantly, "Probably...... Maybe...... No, you can'......"

"What do you mean probably, maybe?" asked Feng Qianyan with a frown, "Can or can't?"

"Uh......" Xiao Jiu hesitated for a moment, but finally opened his mouth, "Normally, it can't......"

"That's what you can!" Feng Tianyan was overjoyed, and hurriedly urged, "Hurry up, how to do it?"

"What did the master do when he repaired his heart?" Xiao Jiu reminded helplessly.

"Wrap the injured heart veins with spiritual power...... Feng Qianyan was instantly enlightened, and his eyes lit up, "You mean, it's the same method as repairing the meridians?"

"Probably...... Xiao Jiu hadn't tried it again, he just heard about it. Whether it succeeds or not, the master will try it himself!ha-" He yawned again.

"Alright, alright, you go back to sleep! I'll try, if it doesn't work, I'll call you again." Feng Tianyan was overjoyed, and quickly cut off contact with Xiao Jiu.

Feng tilted his eyes and pondered carefully: with the help of the Yuhua Nine-fold Acupuncture Method, repairing the meridians with spiritual power is actually a process of exporting spiritual power by oneself and absorbing spiritual power from the meridians. After each repair is completed, he has taken the initiative to withdraw his spiritual power, so will the undamaged meridians absorb the input spiritual power? However, since Xiao Jiu said so, then it may still be feasible. Moreover, Xiao Yuchen's spiritual power is consumed so quickly, he needs to quickly absorb a large amount of spiritual power to replenish it, and it seems that he still needs to choose a relatively thick heart vein to input, and it can be absorbed faster.

After making up his mind, Feng Qianyan stood behind Xiao Yuchen, shook his left hand, and sandwiched three silver needles between his fingers.

"That's ...... It's not cheating, right?" Feng Qianyan muttered a little weakly, pursed his lips, and raised his eyebrows, "Whatever!

Taking a deep breath, he pinched a silver needle in his right hand, and pierced an acupuncture point in Xiao Yuchen's back heart.

The moment the silver needle pierced the skin, Xiao Yuchen's body stiffened slightly.

"It's me, don't move!" the wind whispered, feeling the muscles under the silver needle relax again, twisting the tail of the needle, and piercing deeply.

Three silver needles entered the body, and the wind poured into his eyes, releasing spiritual power and probing into Xiao Yuchen's body. Within the field of vision, several thick heart veins crisscross each other, and near the edge of the view, there is a gray damaged heart vein.

This is......

Feng Qianyan suddenly felt guilty: this is the part of his heart that was hurt by his own palm by the river.
