Yu Sheng's eyes widened before he laughed. "You… are you kidding me?" he asked and checked Fei Yin's wounds. "Have Chen Han hit you in the head too hard - ?" he added while laughing. However, he stopped when he saw Fei Yin's serious expression. "Are you for real?" he said, his eyes widened in surprise. Fei Yin is from another world, too?! He thought.

"The one inside the room is an example." Fei Yin said and glanced inside the room. He's referring to Zuo Zhe.

Yu Sheng then shut up. He's the one who knows the most about Zuo Zhe.

"I'll bear with it since you can't tell me your relationship with Sheng." Fei Yin said. "But, can you tell me what is this Spirit Awakening Method?" he asked. "I don't want any more accidents to occur to him." He explained.

Yu Sheng stared at Fei Yin before he spoke. "The Spirit Awakening Method is increasing the strength of your soul, as well as your body as its vessel." he answered.

"We have learned of that. Sheng's body is self-regenerating." Fei Yin said, then paused. "What about the downside?" he asked.

"It depends on the person." Yu Sheng answered.

Fei Yin looked at him.

"If they continuously advance, they can explode." Yu Sheng said.

Fei Yin's pupils shrank. "What?!" he said, his heart was eaten by fear. He remembered the huge silver ball he and Xie Lan chased. It was Cheng Sheng's soul. How powerful… he thought. But also frightening. If it'd explode – He thought before he stopped. He didn't dare think what the consequences may be. "How can it be stopped?" he asked.

"It will just stop if the person stops cultivating." Yu Sheng answered. "Just like the water. It will continue to flow, but will stop if it'll be stopped." He explained. "The Spirit Awakening Method will only do you good, but harm you if you'll be too excessive on its use." He told him.

Fei Yin sighed in relief. "You really don't intend to harm Sheng?" he asked as he stared at Yu Sheng.

"Why would I harm him?" Yu Sheng asked back, then he smiled. "Even if I initially want to, but now that Zhe is here, I will choose Zhe and follow his wishes." He said and saw Fei Yin's tense expression. "Don't worry. I only plan to help Cheng Sheng. Nothing more than that." He told him and patted his shoulder. "Now, can you make up an excuse to them about Zhe and Cheng Sheng?" he asked him.

Fei Yin's face was covered in dark lines. So this is the exchange of the information about Spirit Awakening Method? He thought. "… fine." He said. As long as it's for Sheng. He thought and left.

Yu Sheng watched Fei Yin leave before the smile on his face disappeared. "Not only the demonic cultivators, and not only Zhe. But also Fei Yin…" he said. "Why are they after Cheng Sheng?" he asked. "Young master… no – " his eyes narrowed and he balled his fists. " – Your Highness. Why are they after you?" he asked and punched the wall beside him. "Have they found out…? No –" he took a deep breath. " – it couldn't be. I already erased the traces leading to our world…" he frowned. "This world is already too strange. As long as His Highness remained strong, His Highness can protect himself." he said to assure himself. That's the reason why he opened Cheng Sheng's spiritual consciousness and made him learn the Spirit Awakening Method.

This world is too dangerous, and Cheng Sheng's soul... it's highly valuable.

Zuo Zhe, who can't sleep, heard what Yu Sheng said. "… haa." He sighed and turned his back on him. "Damn it…" he cursed as he placed a palm on his face. His face was covered in black lines.

System: now you realize the weight of your sin?

Zuo Zhe cried in his heart. That's why I regret now… he thought and remembered how he made a crossover of his two novels.

His first novel is The Tales of the Cultivation World - or better known as The Xianxia Tales to his readers, where Fei Yin is the protagonist. Fei Yin left his home - Shanliang, after having a falling out with his family and went on a journey to find himself. He then arrived to Xinfaxian where he met Xie Lan and Fan Wen, and his fellow disciples Li Tian and Feng Mo. His quest starts when a strange corpse appeared, then someone from the Youxiwang Sect of the West came to summon Xie Lan. He, together with his fellow disciples came with their sect leader to the Xiwang, only to return to Xinfaxian after and saw the Xinfaxian, as well as the other towns and cities in the East, was destroyed. Then, they went to Shanliang - Fei Yin's hometown, to seek help. Much to Fei Yin's chagrin, but his friends' joy since Fei Yin has a relationship with Shanliang. Fei Yin accepted the Shanliangde Sect's help, but still hasn't accepted them. His quest continued from there.

The other novel is The Prince that Fell from the Sky or most commonly known as the The Sky Prince, where Cheng Sheng is the protagonist. He was born with the gods' blessing. However, his beautiful life that should begin took a hundred and eighty degree turn when his parents died and his uncle took over the throne because he was too young. He was then locked up, and time passed and their citizens forgot him. When he grew up, he escaped and then met with Yu Sheng and other people that will help him reclaim the throne.

There are two side stories of The Sky Prince, namely The Tale of the Sun, the Earth and the Moon which is about the story of the three gods that blessed Cheng Sheng - Bai Shen, Hui Shen and Hei Shen, in which Hui Shen is a female. It is a love triangle story. And the other one is The Kingdom Houses A Snake in Its Backyard and A Frog in Its Well which is about the sufferings of Cheng Sheng from his uncle and aunt's hands.

Zuo Zhe didn't know that at that time, there was a space distortion in his world. An explosion happened. Spaces collided and fused, and time overlapped with each other. By the time it was over, he woke up in the cultivation world. Before he could react, he fell on someone and they crashed to the ground. He saw a knight, and his face couldn't be any darker when he realized it was the banished knight guard in the palace from The Sky Prince – Yu Sheng. He felt he was struck by a thunder when he discovered that his two novels had really made a crossover – by starting to fuse. That time, only a small space was opened between the two worlds, and Yu Sheng fell in this world.

Yu Sheng is a capable man. He realized the world he fell in is different and he found Zuo Zhe, who was wearing the clothes of the world they were currently in – xianxia. Yu Sheng then concluded he had traveled to a different world, and made his own clothes like Zuo Zhe. He adapts fast!

Yu Sheng, at that time, had to adapt to whatever was thrown at him, since a war erupted in their world. While he's on his way to the palace to rescue Cheng Sheng, he fell from his horse after an arrow struck his horse. Before he could hit the ground, he fell on the xianxia world. Yu Sheng then tried to look for the portal, only to see it was gone. He burned his clothes to hide his origin, and changed to robes like Zuo Zhe wore.

He captured Zuo Zhe to inquire about the new world, and Zuo Zhe answered each of his questions. When Yu Sheng noticed it was only them two around, Yu Sheng found out that Zuo Zhe might also be from another world. And he was right.

Zuo Zhe told him he's from a different world, far advanced from where they are now - the interstellar world. However, he hasn't told him that he knew of Cheng Sheng. That it was him – Zuo Zhe, who created this mess.

When that time arrived, Yu Sheng was overjoyed to sense Cheng Sheng's presence in this world. He was confused, but he is determined to find him. Though it was faint, but Yu Sheng finally found Cheng Sheng and increased his strength. Yu Sheng was shocked that Cheng Sheng has lost his memories, though. Thus, he is determined to make Cheng Sheng recover his memories. Yes –

"No matter who it is, whether they know about His Highness or not, as long as His Highness wants to go back, I won't let them stop him." Yu Sheng said, his brows knit and his eyes narrowed. His face is determined. His resolve is firm. "I'll protect His Highness." He said.

Yu Sheng was designed to be Cheng Sheng's lover in their world. However -

"Zhe… I'll take you with me!" Yu Sheng said as he turned to Zu Zhe who's 'sleeping' inside the room.

Now two hands covering his face, Zuo Zhe blushed. "… I forgot this poetic side of Yu Sheng!" he said.

System: your focus is on the wrong point!

On the other side, Fei Yin looked at the night sky. "Sheng… I won't let someone take you from me!" he said.
