Walking into Tianlei Valley, the Tianlei dancing in Tianlei Valley immediately attacked Yun Tianyu who broke in without permission, destroying his body, allowing Yun Tianyu to immediately control Zihua Xuanyi to help him resist.

"Tianyu, your body is still too fragile now. You first practice the Tianlei Body Condensation Technique in the outer periphery of Tianlei Valley where the sky thunder is relatively rare. When antibodies against Tianlei are generated in your body, then slowly penetrate deep into Tianlei Valley. In this way, the physical pain you will endure will be much smaller." The great devil was afraid that Yun Tianyu could not bear the pain of Tianlei's body tempering, so he suggested.

"Okay!" Yun Tianyu, who was under the attack of thin heavenly thunder, nodded, sat cross-legged on the outskirts of Tianlei Valley, and began to guide the heavenly thunder attacking his body into his body bit by bit according to the practice method of the Heavenly thunder body-condensing technique he mastered, and tempered his body.

When the first ray of heavenly thunder entered Yun Tianyu's body, Yun Tianyu immediately felt his body being torn apart by the violent heavenly thunder, and a huge pain instantly spread into his soul.

Although the body was painful, Yun Tianyu was determined to endure the severe pain and followed the practice method of Tianlei Condensation Art to merge a ray of Tianlei and thunder guided into his body with his body, tempering his body.

About three hours later, according to the practice method of Tianlei Condensation Art, Yun Tianyu merged the heavenly thunder that was guided into his body as he wished.

However, because the power of a ray of heavenly thunder is limited, the body has been melted into the sky thunder, and it has not enhanced much of Yun Tianyu's physical strength.

"Huh!" The power of the sky thunder disappeared in his body. Yun Tianyu took a deep breath and guided a ray of sky thunder into his body again. He endured the severe pain and practiced in a fusion manner according to the practice method of the Tianlei Condensation Art.

About fifteen hours later, Yun Tianyu only refined five wisps of heavenly thunder, and his body was seriously damaged by heavenly thunder, and it was painful after a slight movement.

"Tianyu, are you okay?" He felt that Yun Tianyu stopped guiding Tianlei into his body due to serious physical damage, and the great devil immediately sent a voice to inquire.

"Fortunately, I need to rest for a few hours." Yun Tianyu, whose face was slightly pale, had a layer of cold sweat on his forehead, took a deep breath and said weakly.

"Well! Don't rush to practice the Tianle Thunder Condensation Art, you can have a good rest." After saying that, the voice of the great devil disappeared in Yun Tianyu's mind.

In order to reduce the attacks of heavenly thunder on himself, when Yun Tianyu was practicing the Original Time and Space Art, he controlled the Lei Ze Ring to release the devouring power, devouring a series of heavenly thunders falling from the sky, and replenishing the reserves of heavenly thunders in the Lei Ze Ring.

After resting for a night, Yun Tianyu, under the rehabilitation of more than 400 earth energy origin particles, his physical damage was mostly restored. He gritted his teeth and continued to guide Tianlei into his body, practicing Tianlei Condensation Technique to temper his body.

In this way, Yun Tianyu relied on his tenacious perseverance to practice the Tianlei Condensation Art for at least fifteen hours a day to temper his body, and practiced for about eight days with his face.

Gradually, Yun Tianyu's body became stronger and lightning power was generated in the physical cells.

Just when Yun Tianyu was practicing in the Tianlei Valley without regard for the severe physical pain, Yuan Xiaoxi, wearing a red floral jacket, rode a brown bear full of brown hair and huge body, appeared outside the Tianlei Valley.

This huge brown bear is the earth bear. However, after several years of cultivation, the earth bear broke through the bottleneck of the earth beast and reached the first level of the heavenly beast realm.

Although the Earth Bear has reached the first level of heavenly beast realm and has the strength equivalent to the seventh level of human Dao Saint realm, facing Yuan Xiaoxi, who has a medium-grade heavenly weapon, mad magic purple gold stick and divine beast bloodline, he has no ability to resist. After being beaten by Yuan Xiaoxi for several days, he obediently surrendered to Yuan Xiaoxi.

"Sister Xiaoxi, that person who is not good at brains and is abused in Tianlei Valley is your boss!" Dadi Feng asked in surprise when he saw Yun Tianyu sitting cross-legged on the edge of Tianlei Valley practicing.

"Big Bear, you are looking for death. I dare to say that my old man is not good at brains. Be careful I will beat you." Yuan Xiaoxi, who was riding on the neck of the Earth Bear, knocked the Earth Bear's huge head hard and warned viciously.

"I dare not, don't dare!" Thinking of Yuan Xiaoxi's terror, the earth-torn bear immediately became honest and apologized repeatedly, and did not dare to anger Yuan Xiaoxi at all.

Feeling Yuan Xiaoxi's appearance, Yun Tianyu, who had adapted to the thunder outside the Tianlei Valley, took a deep breath, left Tianlei Valley, and walked out slowly.

"Boss, are you okay?" Yuan Xiaoxi asked nervously when he saw Yun Tianyu walking out of Tianlei Valley covered in blood.

"I'm fine! I'm using the thunder in the Tianlei Valley to temper my body." Yun Tianyu glanced at Yuan Xiaoxi and the huge earth bear, and shook his head gently.

"Big Bear, call him Boss." Yuan Xiaoxi jumped down from the neck of the Earthly Bear and ordered loudly.

"Boss!" The Earth Bear did not dare to resist Yuan Xiaoxi's order, and made a deafening sound, unwilling to call Yun Tianyu "Boss".

"Xiaoxi, you have conquered this earthly bear." Seeing that the earthly bear was so obedient, Yun Tianyu asked in surprise.

"Well! Big Bear will become our younger brother in the future. Just leave any work you have in the future to Big Bear to do." The cute Yuan Xiaoxi looked like a big sister and nodded slightly.

"The Earth Bear, this thousand-year-old blood vermilion fruit is given to you as a gift. Taking this thousand-year-old blood vermilion fruit should be beneficial to you." Yun Tianyu took out a precious thousand-year-old blood vermilion fruit obtained from the Thunder Ring that had infused a large amount of heavenly thunder and gave it to the Earth Bear.

"Thousand-year-old blood red fruit, thank you boss." The earth bear, who occupied a large number of spiritual herbs and the spiritual fruit, was very conscious of the goods. He held the thousand-year-old blood red fruit given to him by Yun Tianyu in both hands, and thanked him with his eyes shining.

"Okay, the stream, the earth bear, I will continue to practice in the Tianlei Valley, and this practice will take about half a year. If you are bored, you will practice in the Tianlei Mountains. After I have tempered my body, I will use the messaging bead to send you messages." Yun Tianyu reminded him and continued to walk into the Tianlei Valley where the sky thunder was surging and walked towards the depths of the Tianlei Valley.

When Yun Tianyu walked to the central area of ​​Tianlei Valley, he felt that the sky thunder landing in the sky became more and more dense, and the power of Tianlei was even stronger. He stopped moving forward and sat cross-legged in the central area of ​​Tianlei Valley, trying to guide many thunders into his body to practice the Tianlei Condensation Art to temper his body.

When several powerful thunders entered Yun Tianyu's body, Yun Tianyu's body, which had been tempered by Tianyu in the early stage, suffered great losses again. The muscles on Yun Tianyu's shoulders were torn apart by several thunders, and a large amount of blood immediately flowed out. A layer of cold sweat appeared on Yun Tianyu's forehead in pain.

"Yun Tianyu, you are guiding too many heavenly thunders. Take the Yuanling Pill quickly to repair your body." Feeling that Yun Tianyu guided many heavenly thunders into his body, greatly damaging his body, the great devil immediately sent a voice to say.

"Okay!" In the middle of Tianlei Valley, Yun Tianyu's situation was already very dangerous. If his body was damaged seriously, it would pose a fatal danger to Yun Tianyu. So at the moment when the great devil sent a voice, Yun Tianyu took a Huiyuan Spirit Pill without hesitation to repair his seriously damaged body.

Under the repair of Huiyuan Spirit Pill, Yun Tianyu's severely damaged body recovered rapidly. During the recovery of the powerful medicinal effect of Huiyuan Spirit Pill, Yun Tianyu quickly practiced the Tianlei Condensation Art to refine several heavenly thunders in his body, and gradually refined several heavenly thunders in his body.

Yun Tianyu, who refined several thunders in his body and generally mastered his physical ability to withstand his physical body, guided four thunders into his body to temper his physical body.

In this way, Yun Tianyu practiced in the middle of Tianlei Valley with the help of Zihua Xuanyi's defense power for more than two months. The physical defense power rose sharply, reaching a strength comparable to a top-grade ground weapon. Moreover, one-third of the cells in the physical body already contained the power of Tianlei.

"Huh!" Feeling that the central area of ​​Tianlei Valley is no longer suitable for him to continue his cultivation, Yun Tianyu adjusted his heart and resisted the thunder falling from the sky, step by step to the core area where the sky thunder valley is the most dense and powerful.

I thought that my body was comparable to the top-grade ground weapon, and that it could resist the thunder and lightning in the core area of ​​the Tianlei Valley. However, after entering the core area of ​​the Tianlei Valley, Yun Tianyu resisted the attack of the waterfall-like sky thunder and tried to guide the sky thunder into his body, and deeply realized that the power of the sky thunder in the core area was nearly ten times better than that of the sky thunder in the central area. The large number of sky thunder that poured into his body almost tore his body apart, causing Yun Tianyu to take another Huiyuan Spirit Pill to repair the body that was slashed by the sky thunder and forcibly refining the sky thunder that rushed into his body madly.

When the effect of the Huiyuan Ling Pill under Yuntian Feather's suit gradually disappeared, Yuntian Feather, who had already mastered the Tianlei Condensation Technique, quickly refined the Tianlei that was infused into his body several rounds, and slightly adapted to some Tianlei landed in the core area of ​​Tianlei Valley.

However, as the number of heavenly thunders in the core area of ​​Tianlei Valley became more and more numerous, the purple light released by the lower-grade heavenly weapon Zihua Xuanyi became dimmer and dimmer. A large number of heavenly thunders poured into Yun Tianyu's body uncontrollably, destroying his body, forcing Yun Tianyu to swallow the last Huiyuan Ling Pill to his stomach and repair his severely damaged body.

Losing two Yuan Huiling Pills, Yun Tianyu couldn't hold on after forcing it for a week, and had to withdraw from the core of Tianlei and practice outside the core of Tianlei Valley.

Yun Tianyu practiced outside the core of Tianlei Valley for more than a month. After feeling that his body became stronger again, he broke into the core area and accelerated the speed of his body's tempering.

This time, Yun Tianyu relied on Superman's endurance and willpower to persevere in the core area of ​​Tianlei Valley. After practicing for more than a month, he finally cultivated his body to a strength comparable to that of a top-grade earth tool, and all his physical cells contained the power of thunder and lightning.

"It's done, finally succeeded." Feeling the changes in his body, Yun Tianyu, who had been inhuman torture in Tianlei Valley for nearly half a year, breathed a sigh of relief and left Tianlei Valley without hesitation.
