Moreover, possessing a second soul core meant that he must be at least at the level of a Title Douluo. In other words, a night's love-making had made him undergo a complete change and attained the rank of a Title Douluo in one go!

Even Tang Wulin thought that this was unbelievable. It seemed too easy.

Even though his pace of cultivation was already very quick, he estimated that he would need about two years to attain the rank of a Title Douluo while having a firm foundation.

However, to his surprise, he had accomplished that feat at that very moment. There was no need to mention the firmness of his foundation. Not every Title Douluo could possess a second soul core. Even if it was just the first step, it was already an incredible feat. Possessing a second soul core meant that he would not have any bottlenecks in his cultivation until he was at least at rank-95.

This shocking elevation was as different as the heavens and the earth compared to the pain he had to endure when he was younger. Tang Wulin never expected that he would experience such a strange transformation.

He stood blankly where he was for a moment. When he confirmed that he was not dreaming and everything that had happened before this was real, Tang Wulin's heart gradually calmed down.

'Gu Yuena...she must have an unspeakable secret.'

Before this, he had thought that she was worried that he would not be able to protect her, that something was threatening her security. However, it seemed that it was not the case right now. They were both quite powerful already. He had Shrek Academy and the Tang Sect behind him as well. Even if he faced a formidable foe such as the Spirit Pagoda or even the Holy Spirit Cult, it was not like he was powerless against them. If she was willing, she could return to his side if she wanted to. Also, with their current cultivation bases, if they unleashed the Dragon God Transformation, they could even escape with their lives when facing a Limit Douluo, as long as that Limit Douluo was not a quasigod.

So, what was the secret that she had such a hard time telling him? It was not easy for him to try to find the answer. He could only figure things out as he went along.

In any case, he had to become stronger. Tang Wulin was more sure of this than ever. Only if he was powerful enough could he help Gu Yuena when her closely kept secret finally emerged.

The pain in his heart gradually subsided, and a charming gracefulness returned to it. Last night was truly wonderful for him.

Also, he understood Dai Yun'er's motives for her doing what she had to him. For this princess, he could not find it in his heart to hate her. Moreover, it was precisely because of her actions that he and Gu Yuena could get together. Otherwise, he did not know when he would have seen his beloved again.

Now that he thought about it, things did seem rather odd. The morning had broken and he was not at the Tang Sect's headquarters. Yali must have been worried sick. He decided to return before anything else.

He produced a set of fresh clothes from his storage soul device and exited the park. After ascertaining his position, he hastily returned to the Tang Sect's headquarters.

He had just stepped into the building when a light flashed before his eyes. A anxious-looking Holy Spirit Douluo appeared before him.

"Mother," Tang Wulin greeted her hastily.

The Holy Spirit Douluo scrutinized him. Immediately, her eyes registered shock, "What've you been doing? Why do I feel your aura has somehow strengthened?"

His cultivation base had just elevated to the rank of a Title Douluo, so a soul ring was the only thing he lacked right now. Tang Wulin's spiritual power had not gotten used to concealing his own cultivation base.

His expression was slightly awkward. "Mother, let's talk inside."

The Holy Spirit Douluo saw that he had a sore subject and decided not to press further. She pulled him back to her room.

"I was worried sick! In the morning, Xie Xie went to knock on your door. When he went in, he couldn't find you. There were only two soul circuits there which had escaped even my detection. I knew immediately that something had happened to you. Fortunately, you made it back in one piece. What exactly happened?" the Holy Spirit Douluo asked hurriedly.

Tang Wulin fell silent and decided to tell her everything. He needed another person to help him analyze Gu Yuena's thoughts at the moment.

"Mother, there's something I want to tell you. It's about me and Gu Yue, and also Na'er." The Holy Spirit Douluo was more than a hundred years old and had rich experiences. Tang Wulin needed her help in analyzing what was happening to Gu Yue and Na'er. Also, he had complete trust in this godmother of his.

Without her, he would have died in the hands of the Underworld King Douluo Ha Luosa the day before.

"Your disappearance last night was connected to them?" a look of shock appeared in Yali's eyes.

Tang Wulin scratched his head while wearing an awkward expression. "No, they're not related to my departure from here, but they'll come into the picture afterward. Let me start from the top."

Right there, he began with how he and Na'er knew each other since they were young. He told her about how he came to know Na'er and brought her home. Then, he continued with the story of Na'er's disappearance, his parents leaving him, Wu Zhangkong taking a liking to him, and entering Shrek Academy in the end. He recounted everything that had happened. He basically left the processes of his cultivation out. He focused on the relationship between him, Gu Yue, and Na'er. He also told her about the two of them appearing after that and merging into Gu Yuena.

The more the Holy Spirit Douluo listened, the more her heart raced. She looked at Tang Wulin, and her expression was one of bewilderment.

"A person with two souls, who can split into different individuals and merge into one again? I've never heard of such a thing," said Yali without hesitation.

Shocked by her words, Tang Wulin said, "You've never encountered such a thing before?"

Yali shook her head. "No, and I can be sure that there's no record of this in any of the historical books. This must be some kind of mutation. It's special and might even be unique."

"There are records outlining the incidences where soul beasts cultivated into human beings. For example, the Tang Sect's founder, the Thousand Hands Douluo Tang San's wife. It's said that she was originally a hundred-thousand-year Soft Bone Rabbit which cultivated into a human being."

When he heard this, Tang Wulin's heart was shaken. Was she not talking about his biological mother?

Yali continued, "However, even if a soul beast cultivated into a human being, it can't possibly become two people, let alone have some schizophrenic episode. Also, her bloodline is closely related to yours, and she even told you about the Dragon God. I don't remember Shrek Academy's library housing any records about the Dragon God. This story might be real, but it's more probable that she fabricated it. However, there's no doubt that your bloodline is related to hers. That's why so many things have happened. I never knew that Na'er's origins were so mysterious."

"Back then, Na'er had displayed extraordinary talents when she studied with Brother Ming. The pace of her improvement was just like what you displayed recently. Back then, Brother Ming and I thought that he had found his successor. Brother Ming had even thought about passing the position of Sea God Pavilion's Pavilion Master to the little girl Na'er in the future. Her martial soul is the Silver Dragon Spear. If Gu Yue's martial soul is not some Elemental Control, but the Silver Dragon King, as you said, then they might really have the kind of relationship which you just spoke of."

"That's strange, though. What's up with the two of them? Do you know anything about their families?"

Tang Wulin shook his head. "I've never met their families. I only know that Na'er was taken away by her family members back then, and Gu Yue must be from some wealthy family. After that, we've been apart. She's always been very mysterious. Every time we met, she seemed to be sad, especially after the Date Festival. She keeps saying something along the lines of 'she cannot be with me'."

Yali looked deeply at Tang Wulin. Her gaze was slightly strange. "You resemble Brother Ming back then very much, but girls these days! They're bolder than we were back then!"

Tang Wulin's face reddened. "Mother…"

A laugh escaped from Yali's mouth. "Don't think too much about it. I'll do a simple analysis about this for you. Firstly, I think this young girl Gu Yuena means no harm to you, and she really likes you. Otherwise, she wouldn't have given herself to you. Also, I think that there's a deeper dimension in the relationship between the two of you. Otherwise, I've never heard of any love-making session between male and female soul masters that's capable of boosting one's cultivation base from a Soul Douluo to a Title Douluo. That's like reaching the heavens in a single step!"

"With these two points, I can affirm that no matter the situation, she doesn't mean you any harm and she truly likes you. As for what secret she's keeping, we can only wait for her to reveal it. It's too difficult for us to find out right now. When you get back, try to mobilize some Tang Sect forces to investigate her family. Maybe you'll find something. You, for one, shouldn't fret too much about this. She's given you everything and saved your life when you were in danger multiple times. What more do you need? What you should be doing right now is becoming more powerful. If she's really in some kind of danger, you'll be able to help her at that time. Her problem can't stay a problem forever. The time will come when it must be handled. When that day arrives, the truth will be laid bare naturally. Also…"
