However, it is useless to think about these now, and the top priority is to help Xiao Yuchen replenish his mental power first. So, Feng Tianyan chose a section of his heart vein, which was far away from the damaged part, calmed his mind, and began to slowly inject his spiritual power.

And Xiao Yuchen, who was engrossed in arranging the formation, felt that a steady stream of spiritual power began to inject into his meridians after letting the wind pour his face into his body. was startled, and then it became clear to him, presumably Yan Yan had thought of a way to help him replenish his spiritual power. Hurriedly gathered his mind and continued to deploy the formation intently.

With the spiritual power injected by the wind, Xiao Yuchen's face softened a lot, and the speed of the golden thread was obviously faster.

Gradually, Feng Qianyan found that something was wrong, and the damaged gray meridian in the distance actually appeared a little bit of white jade. I suddenly felt that something was wrong: the spiritual power I injected must have been partially absorbed by that meridian!

Xiao Yuchen's spiritual power can only complete two-thirds of the formation, that is to say, the remaining one-third of the formation still needs to consume almost half of his spiritual power. And this damaged heart vein, although not as serious as the previous two times, will consume at least about half of the mental power! In this way, one's mental power will almost be exhausted!

Feng Qiyan was speechless, is this the rhythm of digging a pit and jumping by himself......

However, at this moment, no matter how much you want, it is useless, and there is no turning back. Since you can't give up halfway, you can only hold on hard.

There were still the last two amethysts left on the stone platform, and the gold thread was moving slower and slower, almost like a turtle. Not only did Xiao Yuchen's originally softened face gradually turn white again, but Feng Tianyan's face standing behind him was also extremely ugly.

Feng Qianyan propped one hand on Xiao Yuchen's back, and the other hand tightly grasped his arm, and the long strands of sweat-soaked hair stuck to the side of his face. Xiu's eyebrows were frowning, her eyes were closed, her teeth were biting her lip, and she squeezed out of her mouth word by word: "Xiao Yuchen, you must-must-hold on-"

Xiao Yuchen's thin lips were tightly pursed into a straight line, and her long eyelashes trembled slightly. Under the pale skin, the green tendons on the forehead appear shallowly. In the deep starry eyes, a thin layer of mist evaporated: Yan Yan......

The golden thread passes through the last spirit crystal and extends towards the end, which is the spirit crystal at the beginning.

Feeling that there was only a faint trace of spiritual power injected into his body, Xiao Yuchen's eyes lit up and he shouted: "Yan Yan, let go!"

"Don't let it go!" shouted the wind stubbornly.

Xiao Yuchen clenched his fists and squeezed out two words from between his clenched teeth: "Let go!"

"Don't let it go! It's almost over! You can't give up all your efforts! I can! You concentrate on the formation!" Feng Qiyan's weak voice was full of persistence.

"Yan Yan!"

"Xiao Yuchen!" Feng Tianyan roared angrily, "It's a man, you give me a hurry!"

Taking a deep breath, Xiao Yuchen gritted his teeth and concentrated on squeezing the little spiritual power left to continue to set up the formation.

Little by little, the golden thread approached the spirit crystal at the starting point, getting closer and closer, getting closer and closer...... At the moment when the spirit crystal was shot in, the golden light on the stone platform was magnificent.

"It's done?" Feng Qiyan breathed a sigh of relief, let go of the little hand that was grabbing Xiao Yuchen's arm, brushed his heart, took out three silver needles, and instantly his body softened, and he fell to the ground with a "poof".
