Boom, a thunderbolt struck Xia Yu's back, Xia Yu fell to the ground, covered in black smoke, scorched, numb, and no longer felt pain.

Never give up!

Xia Yu gritted his teeth and crawled the ground, the thunder and lightning around him were still so ruthless, one after another, hitting Xia Yu's body.

Xia Yu felt that his consciousness gradually began to disperse, fluttering, as if the soul was about to leave the body and fly out.

Xia Yu knew that he was going to die, but he was unwilling, he had to use his last strength to crawl forward, crawl forward, crawl forward......

Xia Yu crawled for a while, his two arms were unconscious, he couldn't crawl anymore, he could only squirm forward like a worm, and after squirming for a distance, he finally exhausted all his strength, and his eyelids slowly fell.

"Fuck, it's dead again," Xia Yu scolded in his heart, and his eyes were about to close.

At this time, suddenly the thunder and lightning around him stopped, and a dazzling white light flashed in the red Heavenly Thunder Cave.

Xia Yu thought to himself, it seems that I am not a bad person, I did not go to hell after I died, but went to heaven.

"Little one!~~~"

A shout was like thunder, which shook Xia Yu's whole body, and the flame of life that was about to be extinguished flashed again.

Xia Yu blinked, felt a little more strength, struggled, raised his head, and found that he was still in the Heavenly Thunder Cave, and the Heavenly Thunder Cave was still red, but it was no longer bursting with thunder and lightning.

Xia Yu thought that he had auditory hallucinations just now, but unexpectedly, the voice sounded again, "Little guy!"

Xia Yu looked around, only heard his voice, but did not see him, he endured the pain, stood up, and said, "Who, who is talking to me?"

The old, loud voice rang out, "Little one, I'm talking to you." ”

"Where are you?" Xia Yu asked.

"You can't see me, I'm just a wisp of divine sense, remaining in this Heavenly Thunder Cave, my name is Thunderbolt Ancestor. ”

"Thunderbolt Ancestor?" Xia Yu frowned and asked, "What is your relationship with the Thunderbolt Gang?"

"I am the founding patriarch of the Perak Gang, and I founded the Perak Gang. ”

Xia Yu originally thought that he had met a master from outside the world, and he might be able to help him leave the Thunder Cave, but when he heard that this master from outside the world was the founder of the Thunderbolt Gang, the heart that had just risen out of the water made a grunt, and instantly sank to the bottom of the water.

Xia Yu's voice was fierce and shouted, "What are you going to do?!"

The Thunderbolt Ancestor said, "Little guy, why are you so angry?"

Xia Yu said: "You Thunderbolt Gang did evil, so I fled here, and you still ask me why I am so angry? Come on, if you want to kill you, you have to listen to the respect, frown, the master is not a hero!"

The Thunderbolt Ancestor was silent for a moment and said, "My physical body has been destroyed for thousands of years, and I didn't expect the Thunderbolt Gang to fall to the point where it is today. In any case, I am the founding patriarch of the Thunderbolt Gang, and I am responsible for all the sins of the Thunderbolt Gang, little one, I apologize to you. ”

Xia Yu raised his eyebrows, thinking to himself, listening to this tone, the Thunderbolt Ancestor and Sun Rong are different.

Xia Yu was overjoyed in his heart, but he was still very calm on the surface, softened his tone, and said: "Senior, I was impulsive just now, and I was offended in my words, so please forgive me." ”

"It's okay, it's normal for young people to be a little angry," Thunderbolt Ancestor was still very easy-going.

Xia Yu said: "Senior, can you let me out, I have two companions who are still in Sun Rong's hands, and I want to save them." ”

Thunderbolt Ancestor said: "With your current skills, you may not be able to win Sun Rong alone, Sun Rong still has so many disciples under him, and you will be sent to death in vain if you go out." ”

Xia Yu said: "But I can't hide in this hole for the rest of my life." ”

The Thunderbolt Ancestor said, "Liao Bijun wants to extract the cultivation of your two companions and transfer them to Jiang Zhao's body, this process will take seven hundred and forty-nine days. ”

Although the Thunderbolt Ancestor only had a wisp of divine consciousness left, and although he was trapped in this Heavenly Thunder Cave and couldn't get out, he knew everything that happened in the small cave Heaven very well.

Xia Yu heard that Li Tie and Liu Changsheng were in danger, and he was so anxious that he turned around.

The Thunderbolt Ancestor said, "Little one, if you want to save your companions, make good use of these forty-nine days to improve your cultivation in this Heavenly Thunder Cave. ”

Xia Yu is a smart person, and when he heard that the Thunderbolt Ancestor had something to say, he clasped his fists and saluted, and said, "The kid is stupid, and I ask my seniors to give me some advice." ”

Thunderbolt Ancestor laughed, he liked Xia Yu's cleverness very much.

The Thunderbolt Ancestor said: "I can help you, but the master leads you into the door, and the cultivation is personal, how much you can improve in these forty-nine days depends on yourself." ”

Xia Yu nodded and said, "I know, I will do my best to live up to the cultivation of my predecessors." ”

Just now, Xia Yu broke into the Tianlei Cave, and the Thunderbolt Ancestor noticed it, and the Thunderbolt Ancestor ignored Xia Yu, thinking, a hairy boy, let the thunderbolt chop him to death.

However, Xia Yu rushed out for more than ten miles in the Tianlei Cave, tried his last breath, and held on, but he refused to give up, and this tenacious spirit touched the Thunderbolt Ancestor.

The Thunderbolt Ancestor put away the thunder and lightning, injecting some vitality into Xia Yu, and Xia Yu came back to life.

The Thunderbolt Ancestor wanted to use the thunder and lightning in the Heavenly Thunder Cave to improve Xia Yu's combat effectiveness, he said: "Little guy, I see that you are very persevering, which saved your life, and now I want to tell you that using the Heavenly Thunder to improve your cultivation is very painful, this kind of pain can make people feel painful, do you dare to try?"

Xia Yu smiled slightly, without hesitation, and said, "It is my blessing to be able to comprehend the Heavenly Thunder Divine Power of my predecessors." ”

The Thunderbolt Ancestor laughed and said, "Okay, good, good, good boy, I'm about to release the Heavenly Thunder." ”

Xia Yu clenched his fists, tensed his muscles, put on a posture, and said, "Senior, I'm ready." ”

Boom, boom, boom!~~~

The thunder roared, and thunder and lightning burst out from the cave wall again, and a thunderbolt hit Xia Yu's body.

The taste of being struck by thunder is not pleasant, Xia Yu subconsciously wants to break free, but reason tells him that he can't break free, this is refining his muscles and bones, and he must endure it!

Xia Yu gritted his teeth, his green muscles burst out, his eyes were about to split, and he endured the bombardment of thunder and lightning and did not move.

Thunder and lightning hit Xia Yu's body, causing Xia Yu to be covered in lightning.

The Thunderbolt Ancestor thought that Xia Yu, the shallow cultivation of the three levels of the Spirit Martial Realm, had just begun to use thunder and lightning to temper his muscles and bones, and it would be very good to be able to last for ten seconds. Unexpectedly, ten seconds passed, Xia Yu had no intention of falling, Thunderbolt Ancestor continued to release thunder and lightning, ten seconds passed, twenty seconds passed, thirty seconds passed, and one minute passed......

The Thunderbolt Ancestor didn't speak, he was completely stunned, he forgot the time, and when the Thunderbolt Ancestor came back to his senses, a full three minutes had passed, and Xia Yu was still there.

Thunderbolt Ancestor hurriedly put away the thunder and lightning, and if he continued to release the thunder and lightning, Xia Yu's life would be in danger.

The thunder and lightning receded, and Xia Yu was covered in black smoke, and he fell to the ground with a bang, motionless.

The Thunderbolt Ancestor was a little nervous and asked, "Little guy, are you okay?"

Xia Yu fell to the ground, didn't speak, didn't move, Thunderbolt Ancestor gasped, thinking,, shouldn't you use too much force and beat this little guy to death?

"Little one, little one, little one......" Thunderbolt Ancestor cried incessantly.

Suddenly, Xia Yu let out a sigh of relief, and a carp stiffened, jumped up from the ground, smiled, and said: "Senior, I'm fine, this day's thunder refining muscles and bones are really effective, and I feel that the whole person is much stronger than before." ”

It turned out that Xia Yu was not dead, and the Thunderbolt Ancestor had a false alarm, and then looked at Xia Yu, full of surprise.

It stands to reason that Xia Yu was bombarded by thunder and lightning for three minutes, even if he didn't die, he would be dying, and he would be relieved for half a day, but he didn't expect Xia Yu to rest for less than a minute, and a carp would be resurrected with full blood.

The Thunderbolt Ancestor thought to himself, could it be that this little guy is a genius who has not been met for thousands of years?

The Thunderbolt Ancestor has been in this thunder cave for thousands of years, very boring, very boring, and now he has met Xia Yu, the Thunderbolt Ancestor's thousand-year-old backwater-like heart has rippled layer upon layer.

He wants to use these seven seven forty-nine days to do his best to cultivate Xia Yu, and in the future, Xia Yu will reach the peak of martial arts, and he will also have a glory, which is worthy of this life.

The old ancestor of Thunderbolt used thunder and lightning to temper Xia Yu's muscles and bones, enhance Xia Yu's defense, and then used thunder and lightning to practice Xia Yu's flexibility, release thunder and lightning, let Xia Yu keep dodging, and finally let Xia Yu absorb the power of thunder and lightning for his own use.

The Tiankui Star in "The Book of Sealed Demons" has the power of nature, and Xia Yu can just use the skills of the Tiankui Star to absorb thunder and lightning.

(In "Water Margin", Tiankui Star is timely rain - Song Jiang)

There is no difference between day and night in the Heavenly Thunder Cave, so Xia Yu secretly followed the Thunderbolt Ancestor to cultivate. There is no food or drinking water in the Thunder Cave that day, if Xia Yu is hungry and thirsty, the Thunderbolt Ancestor will replenish Xia Yu's vitality.

With the vitality of the Thunderbolt Ancestor, Xia Yu was not only neither hungry nor thirsty, nor sleepy, he didn't even have to sleep, and all his time was saved for cultivation.

At the beginning, Xia Yu could withstand three minutes of lightning strikes, and after five days of cultivation, Xia Yu was able to withstand ten minutes of lightning strikes, and after ten days, Xia Yu could withstand half an hour of lightning strikes. Later, the Thunderbolt Ancestor had to increase the power of the thunder and lightning, rolling thunder, and bombarding indiscriminately.

The Thunderbolt Ancestor lived in the golden age of martial arts, when there were many capable people and masters, compared with those capable people and masters, Xia Yu did not fall behind at all.

If Xia Yu could possess those cultivation resources in the golden age of martial arts, Thunderbolt Ancestor dared to assert that Xia Yu would be more powerful than any capable person or master he had ever seen.

One day in the future, perhaps on the peak of martial arts, Xia Yu's footprints will be left.
