At midnight.

"Master, the time you set for practice has come. It''s time to start today''s practice!" Xiaoguang''s voice sounded in Wang Kai''s sea of knowledge, waking him from his sleep.

"Yes, it''s time to practice!" practice is like sailing against the current. If you don''t advance, you will fall back. Wang Kai has always put the most critical position in his mind about practice and released a double puppet. Wang Kai''s mind moved and immediately entered a small position!

Sitting cross legged in the open space near the plane stove in the small plane, Wang Kai slowly closed his eyes, put aside his thoughts, and then silently urged Tiangong in taixuan town. Suddenly, the first vortex of soul power condensed in Wang Kai''s heart, and the soul power in the small plane poured into Wang Kai''s body, pushing up the first round of soul power tide!

......

Two hours later.

"Practice taixuan town Tiangong, source experience + 380!"

"Refining residual medicine power in the body, source experience + 260!"

At the end of the 7963 round of soul power tide, the prompt sound of the system also sounded in Wang Kai''s sea awareness, dispersing the seven soul power vortices in his body. Wang Kai opened his eyes and slowly stood up.

"[source experience: 51200 source 70000 source]"

Looking at his own experience slot in the system data, Wang Kai couldn''t help showing a satisfied smile. After this period of hard work, he is not far from the next promotion. As long as it takes another month or so, he can successfully break through and promote to the 58th level of soul king!

For a normal soul king, such cultivation speed is definitely a miracle that can''t be imagined in a dream. However, Wang Kai''s opponent is not an ordinary soul master, but a contemporary son of luck in Douluo mainland. He must have unlimited adventures all the way, and the promotion speed may not be much worse than Wang Kai now!

Not only that, the more the infinite soul system goes to the back, the more experience it needs to upgrade. Wang Kai can''t help frowning at the thought of the massive experience value he needs to upgrade in the future! If he wants to continue to maintain the current cultivation speed, it is necessary to break through the Tiangong of taixuan town to the eighth floor and continuously optimize it!

However, different from the first seven layers of Tiangong in taixuan Town, the eighth and ninth layers of Tiangong in taixuan town need to condense a soul force vortex in the soul master''s cerebellum and brain respectively! As the most vulnerable and mysterious part of the body, once injured, even with the power of the earth and the body of yin and Yang, it is difficult to recover, and may even leave hidden diseases on the body and reduce the promotion potential in the future. Therefore, Wang Kai does not dare to practice rashly for the time being, and is ready to try again after the advanced soul emperor!

At this time, Wang Kai felt the familiar call in his heart. With a move in his heart, Wang Kai came to the place where the spider egg was buried last time.

"Is this little guy hungry again?" Wang Kai thought as he cut open the floating soil and dug out the hatched spider eggs buried under the soil.

——No, it may be hard to be called a spider egg now. Compared with the last time, the volume of this human faced magic spider egg has almost doubled, and the breath of life has increased several times! It seems that after getting the blood from Dugu Bo''s body last time, the little guy really benefited a lot from it.

Not only the change of size, but also after a week of incubation, the runes on the spider egg shell have changed again, revealing a faint threat. At the same time, the dark red shell of the spider egg has gradually faded, revealing the body of the beautiful girl in front of Wang Kai.

——It was a perfect female body whose appearance was about twelve or three years old. Her skin was brighter than snow, her face was beautiful, her long black hair was soft and elegant, her flexible and fresh facial features were impeccable, and her body curve was very melodious, as if the essence of nature and spirit in heaven and earth were all concentrated on her.

However, different from ordinary girls, the beautiful girl in the spider egg has several dark red lines on her body surface, and there is a small eye mark on her forehead. However, these lines and marks do not destroy the girl''s beauty at all, but add a bit of mysterious and wild beauty to her, making Wang Kai have a feeling of shocking her mind.

"Mom, I''m hungry!"

Just then, Wang Kai''s ear seemed to ring out a faint call.

"Mom?" listening to this term, Wang Kai was stunned. However, he immediately thought that although there was no trace of human faced magic spider on the girl in front of him, after all, there was still human faced magic spider blood in her body. Perhaps, from the memory of blood, she mistook herself for her mother?

"Forget it, don''t worry about these first. She looks very smart. After she hatches, correct it slowly." with a smile, Wang Kai condenses a Shura evil spirit between his fingers and gently points it on the shell of the spider egg.

At the same time, the Shura evil spirit between Wang Kai''s fingers was quickly inhaled into the spider egg. Seeing that the Shura evil spirit in his hand was nearly exhausted, Wang Kai thought and sent a large amount of Shura evil spirit to his fingers.

......

In half an hour.

"Mom, I''m full, burp!" the Spider Egg absorbed Shura''s evil spirit more and more slowly. Finally, with a soft burp, the girl''s satisfied voice sounded in Wang Kai''s sea of knowledge. Listening to the girl''s response, Wang Kai slowly pulled back his fingers.

"He absorbed 50% of the total amount of Shura''s evil spirit at one time. He is really a greedy little guy! If you are full, continue to hatch and grow up!" seeing that the consciousness of the girl in the spider''s egg fell into a coma again, Wang Kai also showed a doting smile and buried the spider''s egg back in the pit near the surface stove.

After everything was handled, Wang Kai thought again and returned to Douluo mainland. Two and a half hours later, the sunrise has risen from the horizon. However, Ning Yutian, who is sleeping, will not find that Wang Kai, who is sleeping next to him, once left at night

"Young master Wang Kai, please help you get up!" a ray of morning light spread into the boudoir through the window. Ning Yutian also woke up from his sleep and whispered in Wang Kai''s ear.

"No, I''ll do it myself." listening to Ning Yutian''s call, Wang Kai also opened his eyes and sat up from the bed. Gently sniffing, the girl''s elegant body fragrance still floated at the tip of her nose, and Wang Kai also showed a satisfied smile.

Dressed neatly, Wang Kai and Ning Yutian went downstairs to have breakfast together. This time, Wang Kai enjoyed the ultimate treatment of feeding himself by qianrenxue. Naturally, there was no need to say the beauty. Wang Kai couldn''t help showing an intoxicated smile at the corners of his mouth.

"Mr. Wang Kai, will you continue to go to the library this morning?" after breakfast, Ning Yutian also clasped his fingers with Ning Yutian and left the boudoir.

"Well, yes, let''s go together." after that, Wang Kai and Ning Yutian walked to the library not far away.
