Inside the thunder cave, it is divided into many forks.

At every fork, you can go into the depths.

In this cave, there is a powerful thunder power.

The deeper you go, the more powerful the thunder becomes!

There were signs hanging in the Thunder Cave, and Lin Feng entered a cave where no one was around.

Cracking sound.

Walking into the cave more than ten meters away, I heard the sound of thunder.

Streams of thunder twinkled through the cavern, glowing purple.

"I heard that this thunder cave was formed by the divine thunder from the sky countless years ago, and it was later developed into a thunder cave, which can be used to refine the flesh body!"

Lin Feng thought of the origin of the Thunder Cave and couldn't help muttering.

Bang!

He walked into the depths, and one after another thunder power bombarded Lin Feng's body.

Lin Feng's body immediately became a blur of flesh and blood.

The power of thunder is one of the most violent forces in the world.

Like the so-called Heavenly Tribulation, it is composed of the power of thunder, and monks are often very afraid of the power of thunder.

Because the power of thunder has too much destructive power.

Not something that ordinary monks can afford.

Even in the Thunder Cave of the Qinglong Academy, there are extremely few students who come here.

Because the power of thunder is too damaging to the body, ordinary students who come here are not tempering their bodies at all, and they will be bombarded half to death by the power of thunder in the thunder cave.

Only some students with excellent strength and talent will enter the thunder cave for tempering, of course, it is generally difficult to hold on for too long, and it is already quite powerful to be able to hold on to the thunder cave for an hour.

"What a thunder quenching body, this thunder power really deserves to be the most violent power, even my flesh has been split into flesh, not to mention other people"!

Lin Feng showed a shocked expression.

But he was not afraid.

Lin Feng began to operate the Ancient Dragon Elephant Technique, the power of the Ancient Dragon Elephant surged in his body, and his injured body was quickly repaired by the power of the Ancient Dragon Elephant.

The power of thunder was destroying Lin Feng's body, while the power of the primeval dragon elephant was repairing Lin Feng's body.

In the midst of destruction and rebirth, Lin Feng's physical body became stronger and stronger.

After refining in the outermost area for three hours, Lin Feng continued to walk inside, the further he went, the more terrifying the power of the thunder became, when Lin Feng went deep into thirty meters, the power of the thunder here was ten times more violent than the outer area, and the dense power of thunder bombarded Lin Feng's body.

Pain!

Lin Feng felt a pain like a drill, and he could even see that his muscles were blasted open by the power of thunder, and blood suddenly flowed out.

"Hold on"!

Lin Feng gritted his teeth!

Martial arts is like this, only by persevering can you have the last laugh!

Lin Feng ran the Ancient Dragon Elephant Technique, and the power of the Ancient Dragon Elephant traveled in his body and began to repair his physical body.

Lin Feng's body was destroyed again and again, and it was repaired again and again.

...

Outside.

A tall student came to the Thunder Cave.

This student is quite famous, called "Chu Jianghe"!

This person is the eleventh master of the mountain and river list.

"Senior Brother Chu", seeing Chu Jianghe coming, Wang Yun hurriedly saluted.

"Hmm". Chu Jianghe nodded and entered the Thunder Cave, at this moment, except for Lin Feng in the Thunder Cave, the rest of the cultivation students had already left, and Chu Jianghe walked into the Thunder Cave next to Lin Feng to cultivate.

Chu Jianghe's practice is called, "Xuanyuan Thunder Strength", and his exercises involve "thunder". The attack power can be described as extremely domineering, a monk of the same level can stay in the thunder cave for an hour, but Chu Jianghe can stay for a full day.

This has a great relationship with the exercises practiced by Chu Jianghe.

A day later, Chu Jianghe walked out of the Thunder Cave, he took a deep breath, and said, "This time I persisted for twenty-five hours, which is an hour longer than the last time, not bad!"

Chu Jianghe was obviously very satisfied with his Thunder Cave Quenching Body this time.

Suddenly, Chu Jianghe's eyes looked at the Thunder Cave next to him.

The "Do Not Disturb" sign was still erected there, indicating that there were people inside, Chu Jianghe couldn't help frowning slightly, and he walked out of the Thunder Cave.

Wang Yun said respectfully, "Senior Brother Chu has finished cultivating!"

"Hmm", Chu Jianghe nodded, he looked at Wang Yun and said, "The thunder cave next to me, is it a replacement?"

Wang Yun said with a wry smile, "I haven't been replaced, I have always been the junior brother."

"Senior brother, who is he?", Chu Jianghe asked in surprise.

"It's Senior Brother Lin Feng!" Wang Yun said.

"It turned out to be him, how long has Senior Brother Lin Feng been inside?". Chu Jianghe asked.

"Today is the fifth day!!!" Wang Yun said.

His own face was also full of incredulous expressions.

Lei Dong quenched the body, the previous record was held by Chu Jianghe, even if Chu Jianghe broke his own record again this time, he only stayed for twenty-five hours.

And Lin Feng, the first time he entered the Thunder Cave, he had been there for four days.

"How is that possible?". Chu Jianghe's eyes widened, with a ghostly expression.

Wang Yun said with a wry smile on his face, "It's true!"

Chu Jianghe's heart was shocked, and he said, "Then I'll wait here to see how long this Senior Brother Lin can last."

The news that Lin Feng had been cultivating in the Thunder Cave for four days and had not yet come out quickly spread throughout the Qinglong Academy.

Many people were shocked and came to watch.

And Lin Feng didn't know what was going on outside, he had already penetrated into the Thunder Cave sixty meters away.

The thunder power here is dense, and he can't see his five fingers, he can only see the surrounding violent thunder power, those thunder powers, once bombarded Lin Feng's body, Lin Feng was blasted out again and again, his body exploded directly, dripping with blood, and he looked very miserable, but Lin Feng got up from the ground once, and then frantically ran the Ancient Dragon Elephant Technique, repairing his body.

Under this kind of almost devastating tempering, Lin Feng's physical body became stronger and stronger, and even, in every cell of Lin Feng, the shadow of an ancient dragon elephant was faintly condensed.

It is rumored that the cultivators who cultivate the Ancient Dragon Elephant Technique, every cell of the supernatural power can contain the power of an Ancient Dragon Elephant, and the human body, the body of the cultivator, is composed of a total of 811 billion cells, that is to say, Lin Feng's strength, at the peak level, can reach the power of 810 billion Ancient Dragon Elephant.

Of course, this is only a theoretical value, if it can really reach such a power, it is almost a power that can shake the stars, what are gods and demons? The physical body of gods and demons is too far from Lin Feng, Lin Feng can burst the gods and demons of the same level with one punch, this is the terrifying thing about the Ancient Dragon Elephant Technique, I don't know how long it has been tempered, and the power of thunder at the sixty meter position has been unable to hurt Lin Feng's body.

Lin Feng felt that his physical body, even if it was a divine weapon, could not hurt in the slightest, and it was definitely far beyond the three or four levels of the physical body of gods and demons of the same level, as for the human monks, Lin Feng felt that even the human monks of the Yin and Yang Realm could not compare with their physical bodies.
