Yu Tianlai finally adjusted his cultivation for a day, and the next morning he entered a quiet room to retreat from Yu Mian.

Qiu Moyan knew that his retreat was of great significance, so he used his sword to guard the outside of this quiet room.

Yu Tianlai in the quiet room sat cross-legged, and there were five dragon spirit beads emitting a white light side by side on a few tables in front of him. After the last pranayama and the physical and mental perfection reached the peak state, he raised his hand and took a spirit bead and put it in the palm of his hand, which was already the third time to be recultivated, and the "Yi Jin Sutra" true qi with a degree of purity that was the crown of all the acquired martial artists in ancient and modern times was poured into the spirit bead bit by bit.

In this spirit bead that took shape after thousands of years of nurturing the dragon of the strange beast, there is a trace of aura that is much purer and more condensed than Yu Tianlai's "Yijin Sutra" true qi. This trace of aura is extremely inert and seems to have the weight of a mountain, no matter how Yu Tianlai's true qi is seduced, he lazily lies in the core of the spirit bead and does not move.

Yu Tianlai was not in a hurry, while pouring the true qi into the spirit bead continuously and slowly, so as not to damage the body of the spirit bead that was not very strong and cause the spiritual energy to escape, on the other hand, he urged the true qi injected into the spirit bead from the palms of both palms to rotate up from one positive to the other, from slow to fast, and that trace of spiritual energy was placed between the two groups of true qi that were becoming more and more thick, like two grinding discs rotating forward and backward.

Under the crushing and grinding of the two grinding discs that Zhen Yu Tianlai simulated with true qi, gradually the trace of spiritual energy in the spiritual bead finally changed, and began to collapse and decompose little by little from the outside to the inside, and was absorbed by the upper and lower masses of true qi. And the power of the True Qi Grinding Disc, which fused with the slightest aura, skyrocketed, and the efficiency of grinding and decomposing the aura was also higher.

I don't know how long this kind of water grinding kung fu lasted, and the core and most quintessential point of the spiritual energy in the spiritual bead was finally integrated into the two fans, and more and more spiritual energy was almost completely crushed, absorbed, and fused by the virtual real qi grinding disk, and the elixir-hard spiritual bead that was closed by Yu Tianlai in the palms of his palms also turned into ashes silently.

Yu Tianlai's face showed a hint of joy, and he didn't dare to rewind the two balls of true qi output without the slightest slackness, returned to the body along the arm meridians, and did a Zhou Tian operation along the eight veins of the Qi Jing and one hundred and eight yin veins, and all the true qi stored by tens of thousands of knots along the way merged into it, turning into two galloping and mighty torrents of true qi, all the way up to the top of the head "Baihui Acupoint" at the dantian, and all the way down to the "Yongquan Acupoint" in the heart of the foot.

"Boom!" Yu Tianlai felt an earth-shattering noise in his body, and three true qi torrents hit Baihui and Yongquan at the same time. But this acupoint is like an impregnable embankment, blocking the three true qi torrents to the death, and it will not move even if it is impacted in every way.

Yu Tianlai was still not in a hurry or impatient, and he was engrossed in manipulating the three true qi torrents, impacting the three acupoints over and over again almost in vain. The glimmer of aura that gradually merged into the true qi finally had a wonderful change, and they had an indescribable connection between the darkness and the vitality that diffused in the vast sky and the endless earth.

Under the inspiration of the aura, the originally thin vitality distributed in the void and the earth began to converge towards Yutian, and the scorching heat in the void converged into the "Baihui Acupoint" above his head, and the cold and icy vitality in the earth merged into the "Yongquan Acupoint" of his feet. And the three true qi torrents in his body also made the moment the vitality flowed in, and Yu Yong made an unprecedented fierce impact towards the upper and lower acupoints.

It was another loud bang that only existed in Yu Tianlai's body, like the opening of heaven and earth, Baihui and Yongquan opened at the same time, and the cold and hot two kinds of Yuan Qi flowed through the two acupoints, and after converging with the true qi in his body, they began to run along the meridians and acupoints around the body.

In the process of operation, the true qi and the vitality continue to blend, and little by little they are transformed into another new energy that is more pure and subtle than the true qi and more lively and agile than the vitality - the innate true qi.

Yu Tianlai's figure suddenly bounced up from the futon he was sitting on, and according to the part of the "Yijin Sutra" that he had never practiced, he put his hands and feet in a strange and awkward posture. This is a special use of innate true qi to strengthen and expand the meridians and acupoints, although he used to memorize this exercise thoroughly, but he can only sigh, but now it finally comes in handy.

With the movements he made, part of the true qi in his body that was being transformed from acquired to innate transformation was absorbed by the meridians and acupoints around his body. The meridians and acupoints that had absorbed these newly transformed purest innate true qi began to slowly widen and reinforce, changing from the original ponds and streams to lakes and rivers.

I don't know how long it took, the true qi in Yu Tianlai's body has been followed by the meridians around his body for nine hundred and eighty-one cycles, and the original acquired true qi has all been transformed into innate true qi, and all the meridians and acupoints have been widened and strengthened tenfold.

He froze in place, feeling that the Heaven and Earth Yuan Qi was still slowly but continuously flowing into his body through the "Baihui Acupoint" and the "Yongquan Acupoint", and fused with the Innate True Qi that no longer gushed out from the acupoints around his body all the time to transform into Innate True Qi.

Yu Tianlai sensed that with the help of the vitality that flowed into his body at all times, he established a faint but tangible connection between the small world in his body and the big world outside his body, and he also had a deeper knowledge and understanding of the many mysteries that existed in this heaven and earth for eternity.

He turned around suddenly, opened his right hand and grabbed a few cases five feet away, and when he landed, a wisp of innate true qi emanated from his palm, condensed and scattered five feet away, and flew back into his hand with his mind as if he had a spiritual hand to roll up the remaining four dragon spirit beads on the case.

Yu Tianlai's accumulation in the acquired realm is too strong, and after this serious injury, he was already on the verge of breaking through, so the five dragon spirit beads that were prepared were completed with only one use.

He put away the spirit bead, pushed open the door and walked out. The figure flashed in front of him, Qiu Moyan had already appeared in front of him, and asked with a look of surprise: "Brother Yu, have you succeeded?"

Yu Tianlai nodded with a smile, and Qiu Moyan smiled happily and was sincerely happy for him.

Yu Tianlai saw Qiu Moyan's expression and looked quite tired, calculating that the time it took for him to break through this time had exceeded a time, and this girl had been working tirelessly to protect the Fa for herself, and her heart couldn't help but be greatly moved. was about to persuade her to hurry up and rest, but Qiu Moyan said: "It's the right time for Brother Yu to leave the customs, not long ago my brother-in-law sent someone to ask, saying that there was a guest in front of him, and I hope that Brother Yu can go to see him after leaving the customs." ”

Yu Tianlai asked with some confusion: "Mo Yan knows who is here, since he is Brother Yu's guest, why do you want me to go out to meet him?"

Qiu Moyan said a little casually: "I heard that it is a member of the staff under the new governor of Zhejiang, and his name seems to be Zhou Huai'an!"
