After the battle with Rahu, although Li Yi's divine soul was severely depleted, he returned to Penglai Island to recover.
Primordial Tongtian guarded Li Yi, and in order to help him recover sooner, Tongtian gave Li Yi the Pure World White Lotus, which aids cultivation and was naturally of great help to Li Yi.
During Li Yi's recovery, he felt his cultivation was much faster than usual and attributed it to the Pure World White Lotus, not thinking much of it.
However, Li Yi did not realize that as he cultivated, the gray bead in his purple mansion was emitting strands of purple energy that nourished his divine soul.
On the twelfth year of Li Yi's divine soul recovery, he felt he was mostly healed and decided to set off for Buzhou Mountain. Although Primordial Tongtian initially tried to persuade Li Yi to fully recover before leaving, after a reprimand from Li Yi, he reluctantly agreed to head for Buzhou Mountain.
As Li Yi, Tongtian, and Primordial left Penglai Island, Tongtian said, "Brother, we are not in a hurry. If we are careful along the way, we might find some spiritual treasures and herbs to replenish our divine souls."
Hearing Tongtian's words, Li Yi said, "Now that you mention it, I remember finding a healing sacred medicine on Penglai Island when you and Yuan Shi were refining spiritual treasures."
He then took out a few drops of San Guang Shen Shui and offered them to Tongtian and Yuan Shi.
Yuan Shi and Tongtian looked at each other and said, "San Guang Shen Shui?"
Li Yi replied, "Indeed, it is San Guang Shen Shui. If you hadn't mentioned it, I would have forgotten I had such a good healing medicine."
He then divided the San Guang Shen Shui collected on Penglai into three portions, handing the other two to Yuan Shi and Tongtian.
Yuan Shi and Tongtian said, "Brother, on that island, you gave us the Twelve-grade Pure World White Lotus and the Twenty-four Dinghai Pearls. We cannot accept this divine water."
Seeing their firm expressions, Li Yi laughed and cursed, "Fine, fine, if you two rascals don't want it, then I'll keep it! We are brothers, there's no need to be so formal. If you need it in the future, just come to my Tai Qing Peak to get it. However, it's better to keep some with you for added protection in case of danger."
Saying this, he divided out two small portions for Yuan Shi and Tongtian.
Seeing that their elder brother insisted, the two of them might be beaten if they refused, so they accepted them.
Li Yi nodded with satisfaction, took out three drops, and swallowed them to refine the San Guang Shen Shui.
Seeing Li Yi meditating, Yuan Shi and Tongtian did not disturb him and quietly sat in meditation on the clouds.
Li Yi was very pleased. Although the journey to the East Sea was eventful, it also made Yuan Shi and Tongtian realize the importance of strength, and they would surely cultivate more diligently in the future.
A hundred years passed, and Li Yi and his companions finally reached Buzhou Mountain. Yuan Shi and Tongtian were as shocked by the grandeur of Buzhou Mountain as Li Yi was the first time he saw it.
Li Yi quietly watched Yuan Shi and Tongtian.
When Yuan Shi and Tongtian had recovered somewhat, Li Yi said, "Let's go to the mountain peak to pay respects to Father God."
Yuan Shi and Tongtian nodded.
Li Yi continued, "Buzhou Mountain has the pressure left by Father God. Every step forward increases the pressure. Last time I came, I only reached the mountainside. This time, the three of us should be able to reach the summit together."
With that, Li Yi began to climb Buzhou Mountain. Seeing that Li Yi had started climbing, Yuan Shi and Tongtian followed him.
The moment Yuan Shi and Tongtian touched the mountainside, they felt a burden added to their bodies.
The three of them slowly walked step by step towards the summit.
When Yuan Shi and Tongtian reached one-third of the way up, they were already struggling to move.
At this point, Li Yi said from ahead, "Although this pressure is immense, it is also beneficial to you. Do not give up. I can still bear this pressure for now. Your cultivation is lower. When you reach your limit, the three of us will climb together."
Yuan Shi and Tongtian gritted their teeth and nodded.
The three continued towards the summit of Buzhou Mountain. After reaching halfway, Tongtian could no longer advance.
Tongtian said, "Brother, Second Brother, I feel I have reached my limit and cannot move further."
Li Yi and Yuan Shi stopped. Li Yi said, "Use all your strength to take one more step upwards."
Tongtian heard this, exerted all his strength, and took a step. Tongtian collapsed to the ground with a thud, and blood seeped from every pore.
Yuan Shi was shocked and quickly went to Tongtian's side, looking at Li Yi and asking, "Brother?"
Li Yi said, "Don't mind him, he'll be fine in a while."
As soon as he finished speaking, Tongtian was enveloped in boundless golden light. Li Yi put a few drops of San Guang Shen Shui into Tongtian's mouth.
Soon, Tongtian recovered and stood up from the ground. His cultivation had also entered the mid-stage of Da Luo.
Yuan Shi looked at Li Yi and asked doubtfully, "Third Brother, what is this?"
Li Yi smiled and said, "Both you and I have not fully absorbed the merits of creation in our bodies. Using the pressure here can help us absorb these merits completely."
Yuan Shi understood and nodded, "So that's how it is."
After Tongtian's cultivation reached the mid-stage of Da Luo, Li Yi and the others continued to ascend Buzhou Mountain.
Upon reaching two-thirds of the way, Yuan Shi also reached his limit. Like Tongtian, after collapsing, his cultivation successfully advanced to the late-stage of Da Luo.
Finally, when they reached four-fifths of the way, Li Yi also felt that it was difficult to move. Yuan Shi and Tongtian were even weaker. Li Yi summoned the Xuan Huang Tower to cover them, allowing them to reach this point.
Li Yi said, "The three of us were transformed from Father God's primordial spirit. We have now reached our limit. Why don't we have our primordial spirits emerge, combine the Three Pure Ones, place our physical bodies in my Xuan Huang Tower, and return to them after reaching the summit?"
"What do you think, Second Brother and Third Brother?"
Yuan Shi and Tongtian nodded, "As Big Brother wishes."
With that, a mystical light flashed across their bodies, and a miniature figure appeared at the center of their foreheads, identical to their physical bodies. As it slowly left their foreheads, it gradually grew larger, eventually becoming the same size as their physical bodies.
After their primordial spirits separated, Li Yi summoned the Xuan Huang Tower and collected the three physical bodies within it.
Li Yi looked at Yuan Shi and Tongtian and said, "Let's merge the Three Pure Ones."
Yuan Shi and Tongtian nodded.
With that, Li Yi transformed into a ball of Tai Qing Xuan Qi, while Yuan Shi and Tongtian transformed into a ball of Yu Qing Xuan Qi and a ball of Shang Qing Xuan Qi respectively.
The three balls of Xuan Qi slowly merged. As they fused, the surrounding spiritual energy of heaven and earth surged towards them, forming a giant at the place where they merged.
After the giant was formed, the Tai Qing Xuan Qi that was Li Yi slowly ascended to the giant's brain.
The Yu Qing Xuan Qi that was Yuan Shi was distributed from the giant's neck to its abdomen.
The Shang Qing Xuan Qi that was Tongtian was distributed from the abdomen downwards.
After the Three Pure Ones merged, Li Yi and the others felt as if the Pangu pressure on Buzhou Mountain had disappeared, and they could no longer feel it at all.
The giant then ran wildly towards the summit and soon reached the top.
Upon reaching the summit, the giant disintegrated and transformed back into Li Yi, Yuan Shi, and Tongtian.
Li Yi shook the Xuan Huang Tower gently, and the three physical bodies appeared before them.
The three transformed into streaks of mystical light and entered their respective physical bodies. Soon, the three opened their eyes.
Strangely, after reaching the summit, the pressure no longer affected them.
The three then came to the center of the summit, knelt on the ground, and said, "Tai Qing (Yu Qing, Shang Qing) pays respects to Father God. We will inherit Father God's will and dedicate ourselves to building the Great Desolation into a peaceful and prosperous world."
After speaking, they bowed to the void in worship.
Just as the Three Pure Ones finished their worship and were about to rise, a golden blood suddenly appeared in the void, splitting into three and shooting into the center of each of their foreheads.
Before Li Yi could react, he felt something enter his mind. He quickly checked and saw a golden blood radiating golden light in his sea of consciousness.
As Li Yi's consciousness touched the blood, a cultivation technique, "Nine Revolutions Mysterious Art - Upper Volume," appeared in his mind.
Li Yi rejoiced and quickly looked at Yuan Shi and Tongtian.
Yuan Shi said happily, "Brother, I have received Father God's cultivation technique, 'Nine Revolutions Mysterious Art - Middle Volume.'"
At this, Tongtian said, "I received 'Nine Revolutions Mysterious Art - Lower Volume.'"
