After traveling for a few days, they finally reached Heaven Dou City. The carriages were stopped outside the city because they were not authorized to enter the imperial capital.

Xiaogang paid them the amount already agreed upon. Afterward, they entered the city under his guidance. Although, the guards on the gate were a bit suspicious about them. Yet, after seeing the token handed out by Liu Erlong, the guards obediently allowed them to enter the city.

Everyone here was a mature person and did not get fascinated by the colorful streets. They all looked towards Xiaogang and waited for his instructions.

The teachers of the Shrek academy did not have any other option. They did turn towards their dean at first but what made them speechless was that the other party was daydreaming; moreover, they saw Flender drooling.

" Cough! " Zhao Wuji could not stand it anymore. He coughed lightly and said, " Oye Flender, don't continue to embarrass us. " Naturally, only Flender could hear his voice. For a spirit-emperor, this kind of thing was no big deal.

" Huh! " Flender, who heard Zhao Wuji's voice, snapped out of his dream and looked around to see what had happened. Only to see everyone looking at him strangely.

Worthy of Shrek academy's dean, coupled with Zhao Wuji's strange message and their strange gaze, he instantly figured out the situation.

" Cough! I was thinking about the future of our academy. " Flender, who knew that he had been caught, shamelessly explained himself.

" Boss Fu, were you thinking about the future of the academy or the gold coins the academy would earn? " Xiaogang, who apparently seemed to be in a good mood, came forward to tease his elder brother.

Everyone laughed after hearing his words. On the other hand, Flender glared at him. Soon, they reached their destination and stopped outside the Blue Tyrant Academy.

All of them walked inside the gate and saw a person rushing towards them quickly.

" Welcome back, dean. " It was Yin Shu, one of the prominent teachers in the academy. It was his turn to sit at the office for registration. He would have never thought that his luck would be so good to meet the dean as soon as he accepted the duty.

Liu Erlong nodded, " Okay. " She pointed towards Zhao Wuji and others and said, " Arrange the best available rooms for the new teacher. "

Yin Shu was dumbfounded for a bit before he carefully looked at the five new teachers, who came back with the dean. His face changed after finding that he could only probe the youngest among the five; moreover, the latter's strength was not weaker than him. Meaning that the other person is a genius and a spirit-king similar to him.

" Yes, dean. " Yin Shu agreed without any questions. " Seniors, please follow me. " He turned towards Zhao Wuji and others and spoke with a smile on his face.

" Okay. " Zhao Wuji took the lead, and the rest of them followed him. Soon, the group of six people walked away, leaving Xiaogang, Erlong, Flender, and Little Yan, the four of them.

The four of them walked towards Erlong and Xiaogang's residence. It did not take them long to enter the building and stopped outside the room.

" Boss Fu, the room next to ours is yours. Here is the key. " Erlong took out a small key from her storage device and handed it over to Flender.

She continued, " Boss Fu, please be ready. We will go to the main office after a while. "

" Okay. " Flender nodded. After a small chat, he also left and entered his room.

The three of them also entered their house and quickly freshened up. After a while, Erlong asked, " Xiaogang, what do you plan to do? Do you want to come together? "

He knew where she wanted him to go with her. It was nothing more than handling the affair of transferring the academy to Flender. With her and Boss Fu's current strength, it should be a piece of cake.

Yu Xiaogang shook his head and rejected, " No. I have had some inspiration and will meditate for a while to digest these new gains. "

Now that he has decided to visit Spirit City. It is naturally not possible for him to safely retreat with his current strength.

So he decided to enter the small space inside the black pearl and absorb the fifth spirit ring and break through the next level.

" Okay. " Although she was a bit disappointed, yet after considering his nature, she did not force him.

Soon, Xiaogang was the only one left inside the house. Erlong and Flender had gone to the main office. Whereas the little girl also walked out to play.

With a single thought, he entered the small space inside the black pearl. Without wasting any second, Xiaogang stepped forward and sat beneath the divine core.

He began running the Divine Codex and started absorbing strands of energy from the divine core. His speed of swallowing the energy was twice as fast as compared to the past.

Soon, he heard the familiar clicking sounds from within his body, indicating that he had broken through the next level.

Xiaogang's imposing manner continued to rise as his level rose quickly from 42 to 43, 44, 45, and finally level 50.

Finally, he stopped absorbing the energy, and a smile appeared on his face as he checked his body.

Xiaogang shook his head and meditated for a while to maintain his peak status before he started condensing a spirit ring using the divine core.

A white spirit ring formed above his head, and it's color changed from the initial white to yellow, purple, and finally black.

The only difference between the present spirit ring and the previous one was that the current spirit ring had a tinge of red color mixed in it, showing that it's age was more than 80,000 but less than 100,000 years old.

With a single thought, an illusionary black dragon appeared behind him. The presence of his martial spirit attracted the spirit ring above him.

The spirit ring slowly started condensing as it slowly descending over his martial spirit.

The process of absorbing the spirit ring was short and smooth. As he started absorbing the spirit ring, strands of warm energy entered his body, and after a full circulation, it merged with the three cores within him. On the contrary, other spirit-masters have to endure burning energy breaking into their body every time they absorb a spirit ring.

The warm energy improved his skin, muscles, internal organs, bones, and blood. Overall it raised his body to a new level. Even his physique, " Innate Devouring Body, " also showed improvement.

The three spirit cores within his body absorbed most of the energy and completely solidified. Their size alone doubled as compared to the past.

Yu Xiaogang's spirit power increased to rank 52 after successfully absorbing the fifth spirit ring.

After meditating for a while, an illusionary black field appeared with him as the center. Looking at this field, he smiled. Yes, the biggest gain after absorbing the spirit ring was neither the improvement of his physique nor the fifth spirit ability; rather, it was his innate domain.

After breaking through the spirit-king realm, Xiaogang finally awakened the elementary level of his innate domain, " Devouring domain. "
