The fusion continued. Su Yu focused silently as he used the Soul Expanding Art to stabilize his sea of willpower. That way, his opponents would not be able to easily break through or damage his sea of willpower during combat. This was his favourite move during combat so it was only natural for him to take precautions against it. He started hammering himself madly. The hammer flew everywhere in his sea of willpower, hammering down repeatedly to strengthen the sea. "The calm character is quite powerful. I need to watch out as Great Zhou King might be able to sense me through it." This was one of the reasons Su Yu had been focusing on only natural characters as of late. He had been avoiding willpower texts, especially those written by Invincibles. So far, he had formed several characters from the willpower texts of Invincibles. Most of them were rarely used, but Great Zhou King's calm character was too useful. Thus, he had been using it frequently, making it far easier for Great Zhou King to sense him. In fact, he once considered giving up on this character. But he couldn't bear himself to let it go. The character was simply too useful. Without that character, he would be akin to a bright light bulb whenever he tried to kill someone. With that character, he would be a shadow. "I guess I'll keep using it for now." His sea of willpower continued transforming. The second set of forty apertures was fusing. Clearly, these apertures were trying to take him straight to the ninth-stage Mountainsea Realm. "I'll take it slow. There is no rush." Even at the ninth stage, he would be stuck there for a while. Reaching that stage wouldn't give his combat strength that much of a boost anyway. His advancement might seem fast, but he had actually taken an entire day for it. He had only shut his eyes for a bit. When he reopened them, it was a new day. The twenty-eighth day since the mansion opened. If the entrances still worked, they would start transferring those inside out of the mansion the day after tomorrow. "I can't keep wasting time." When he opened his eyes, He Tu, Dummy, and Xing Yue noticed it. He Tu sighed and asked, "You're a Mountainsea already?" "The path of cultural researchers is hard to walk. But you sure have gone far in the physical path. Your talent...is enough to make you a human king even in the ancient past." Su Yu smiled, "I can accomplish the same even in the current era." He Tu said, "You never know. Is your yin aperture open?" "Not yet." Su Yu's smile widened as he said, "But I can feel it. It won't be too hard to open. I have opened all my apertures." At that, 360 dots of light appeared on his body. He had theorized the existence of the source soul acupoint a long time ago. And now, he was finally going to prove this theory. The source acupoint and soul aperture could ultimately be connected, akin to the connection between the yin and the yang. During the ancient past, the result of this connection was known as the heaven acupoint. Su Yu personally preferred calling it the source soul acupoint. Abruptly, a massive moon lit up in Su Yu's sea of willpower. Waves of gentle power rushed out of it. This power was similar to death qi, but it was no death qi. It was gentle, the opposite of the berserk power of the yang acupoint. This might be the reason for them to complete each other. Originally, the two were not connected to each other. But the moment the yin aperture was opened, a tunnel appeared in the sea of willpower, connecting it elsewhere. Then, a burning sun appeared opposite the gentle moon. They came together automatically. Su Yu's vision blurred. Then, he found himself floating in the air. He saw his own body. He saw numerous things. He saw a new acupoint in the space between his eyebrows. Source soul acupoint. That acupoint was as bright as the sun. It stayed there for a short moment before branding itself on the space between the eyebrows. At the same time, a faint imprint appeared on Su Yu's forehead. Unlike the flame symbol on the forehead of devils, it was a shining miniature gate. It resembled the White Jade Gate in appearance. When the Heaven Gate opens, the myriad realms bow in obeisance. He Tu blanked out. Xing Yue blanked out as well as she muttered, "The Heaven Gate is open." Heaven Gate. How many people had opened it since the beginning of existence? A faint, saintly light started coming out of Su Yu's body while a floating book appeared before him. On his forehead, the Heaven Gate shone brightly. He Tu had a sudden, strong urge to drop to his knees and pay his respects to the bearer of the Heaven Gate. He was doing this out of instinct. Beside He Tu, Xing Yue also bowed slightly, driven purely by her instincts. Her mind was blank. She felt as though she was looking at an ancient existence, an existence she was incomparably familiar with. He Tu recovered almost immediately. A look of boundless shock covered his face. He had nearly dropped to his knees, as though he was welcoming the arrival of an ancient king. Xing Yue shook as she muttered while staring at Su Yu, "You...Time Sage...I...I met the Time Sage before..." This was the Time Sage! Su Yu frowned slightly, but he unfurrowed his brows shortly after and said, "Lord, I am Su Yu. Not the Time Sage." Just then, Dummy clasped his head in pain as he stared at Su Yu while the look in his eyes switched from clarity to blankness repeatedly. After a while, he gnashed his teeth and said, "Time Sage...Time Sage...Culture King...Culture King...You're Culture King...I...I did not betray Culture King...I didn't...I only...only...passed the multiple character legacy...on...I did not...dit not rob the tomb...I didn't..." Su Yu blanked out slightly. Making sure to cover himself in even more saintly radiance, he smiled and asked gently, "Calm down, Xia Chen. You are the keeper of my grave. Aren't you?" "Yes...yes...Lord Culture King...I...Xia Family...for generations...watched over the grave...I am...not a graverobber...the tomb shook....it wanted to...leave..." Su Yu blanked out slightly again. With the same gentle tone, he asked, "Was Xia Wushen aware of this?" "Wushen...Wushen...is not from the...keeper's line...he...he is not a cultural researcher...I am...the gravekeeper of this generation..." Su Yu exhaled in relief. Dummy continued struggling in pain for a while. After one last painful groan, he returned to his usual blank state. Su Yu didn't know what to say anymore. Fortunately, he had learned more. Sure enough, Xia Chen was Culture Tomb's gravekeeper. That was a rather respectable position. With a grade-four authority in the mansion, it was comparable to the status of a marquis. He seemed to have left the grave with the Culture Tomb and founded the multiple character faction. Ultimately, he encountered an unforeseen trouble and perished. It was likely that he had been very strong all along. He had merely been pretending to be weak. Why? Why did he pretend to be weak? Was the Culture Tomb the reason? Su Yu guessed that the unforeseen trouble must be related to the Culture Tomb as well. Sure enough, the Culture Tomb was an inauspicious object. If even someone as strong as Xia Chen could die because of it, just what secret was the Culture Tomb carrying? Su Yu was curious about one more thing. Xia Chen had mistaken him as the Culture King, as though Xia Chen himself had met Culture King before. Was that the case? Perhaps he had merely imagined how the Culture King looked. Xing Yue stared at Su Yu blankly. After a long while, she said, "You...Are you the Culture King? Or are you the Time Sage?" Su Yu smiled, "I am only myself. Who else can I be?" He laughed and continued, "Are you saying that the people of the ancient past believed in the concept of reincarnation?" Xing Yue said nothing. He Tu stared at Su Yu for a long while as well. Finally, he sighed and said, "No, but there is a concept of possession, like what the Devil Pseudo Emperor has been doing. However...you have changed completely after opening your Heaven Gate." Su Yu asked with the same gentle smile, "How am I different? My body is filled with death qi. I am more dead than alive. Am I supposed to be as handsome as before?" He Tu repeated, "You opened the Heaven Gate." "Throughout time, very few people have opened the Heaven Gate. At the very least, I have not encountered one from the first epoch until now." Su Yu replied with a silent smile and started focusing inwardly instead. He no longer needed to keep his yang acupoint sealed. With the fusion of the aperture and fusion, Su Yu felt as though a certain door in his body had been shut. He could freely open or shut it at any time. His willpower and source qi started mixing inside the door. He had a feeling that with the source soul acupoint, he could be more flexible with his energy usage. When he lacked willpower, he could convert source qi into willpower through the Heaven Gate. Sure enough, there was a connection between the two. Both the sea of willpower and the physical body were a part of one's being. It was reasonable that both were connected. In the past, the two had been separated, resulting in an inability to freely convert one to the other. Su Yu muttered to himself, "I understand now. After forming a grand cycle with the 720 acupoints and apertures, the power of the Heaven Gate will all be my power. I no longer require external power. Prior to this, I require external power to supply myself with willpower since there is no connection between the two." That was consistent with what Xing Yue said earlier. Su Yu had finally understood this point after opening all his acupoints and apertures. He looked at Xing Yue and said, "Lord Xing Yue, when I acquire the grand cycle circulation method, I will no longer need your supply of death qi." With the proper cultivation method, he would be able to properly utilize the Heaven Gate. He could feel that he had grown even stronger than before. After completing his nine transformations, his physical strength had reached about sixty-six million acupoints. His willpower cultivation wasn't too helpful in terms of combat strength. But with the Heaven Gate open, his source soul acupoint could give him a boost of about fifty percent in strength. That pushed his strength to a level of roughly a hundred million acupoints. He could freely shut the Heaven Gate, and in such a state, he could still utilize the strength of sixty-six million acupoints. He no longer needed to feed his yang acupoint with Xing Yue's support or his own energy. Now, he only needed to fuel the acupoint when he needed to use it. Xing Yue glanced at him and said nothing. Su Yu had stopped absorbing her death qi. Sure, he would still need to do so during combat. However, that would only last until the day he found the proper cultivation method for his 720 acupoints and apertures. At that time...would he still need her? The moment that thought surfaced in Xing Yue's head, she stared at Su Yu coldly and said, "Are you sure you can live that long? Also, the proper cultivation method for 720 acupoints and apertures might have existed during the ancient past, but it was probably extremely rare even back then."
