Qin Feng did not have time to hesitate. He immediately put Lie Ao back into the system. Although he knew that the result of doing this was likely to be his death, he could not watch as Lie Ao was killed.

When Lie Ao entered the system, Qin Feng felt its weak aura. Although the feeling was very weak, it at least proved that Lie Ao survived.

Boom!

The lightning above his head descended again. Qin Feng instantly fell into the sea of lightning. He had always suspected that he was a cultivator with full spiritual roots. Normal lightning strikes were useless to him, but the power of the Nine Transformation True Lightning made him instantly collapse.

A layer of blue light shot out from his body. Under this violent thunder, the Vajra Spell broke through again and upgraded to the fourth level of the Holy Thunder Body.

However, the layer of blue light on Qin Feng’s body flashed and was instantly destroyed by the power of the thunder. Even the Holy Thunder Body was only invincible in the Saint King Realm and could barely resist the attack of the Buddha Realm cultivators. However, under Empyrean Mainland’s killing thunder tribulation, it was completely vulnerable.

Qin Feng was not in the mood to celebrate the breakthrough of the Vajra Spell again, because he did not know whether he could survive this thunder tribulation. When the blue and purple lightning struck his body, it was like being whipped by countless steel whips, wanting to tear his body into pieces.

Qin Feng felt that his consciousness gradually disappeared again. At this time, the Creation Formula began to operate on its own, and the speed of its operation became faster and faster. What changed was that the aura in his body was rolling crazily, as if a small vortex was formed in his body.

“Thunder Source is like a sea, a sea of lightning filling the sky…”

An old voice rang out in Qin Feng’s mind. He was sure that it was not the voice of the System. However, when the voice rang out, Qin Feng’s consciousness quickly recovered. His brain became abnormally clear. He looked up at the sea of lightning that filled the sky. He recalled the words of the True Art that appeared in his mind sea. It was as if he had suddenly gained some enlightenment.

“First form of the Thunder Heavenly Art, Lightning Attraction!”

A white light flashed in Qin Feng’s mind sea. He suddenly grabbed the white light and instinctively leaped up, slashing towards the void.

The Genuine Yi Sword sent out a blue sword light. The sword light was like thunder, and it instantly brought up more than ten bolts of lightning to the sky.

The two bolts of lightning collided in the void, making a violent noise. However, the lightning that Qin Feng sent out was still too weak, and it was instantly destroyed by the lightning tribulation.

Crack! Crack!

Another few bolts of lightning smashed onto Qin Feng’s body. His body suddenly twitched a few times, and he struggled to swing his second sword.

“Lightning Heavenly Art’s second form, Lightning Transformation!”

This time, the sword light transformed into several blue lightning birds that soared into the sky. They had the aura of wanting to blow up the void. However, when the lightning struck the lightning tribulation, Qin Feng seemed to hear the wails of death. Those lightning birds instantly dissipated.

Rumble!

It was as if even the lightning tribulation was aware of Qin Feng’s strong resistance. The remaining ten or so lightning bolts fell at the same time. Each lightning bolt was as thick as a person’s waist. Wherever it went, the air would explode. It was a formation that could destroy the heavens and earth.

Qin Feng was in the sea of lightning. When he raised his head, he could see the spectacular scene of lightning crossing each other. At this moment, death was very close to him, but he no longer felt nervous. His heart was like a pool of stagnant water, and nothing could make him stir up waves.

The Thunder Heavenly Art was the reward given by the system after he created the Shadowless Saber. It was a high-grade earth-level thunder technique with infinite power.

However, Qin Feng had only comprehended the first two moves at the moment, but when the sea of lightning was about to fall to the ground, he had an epiphany for the rest of his life after death!

“The thunder essence is like the sea, the sea of lightning…”

Qin Feng’s eyes lit up, and his sword pierced through the air. “The third form of the Thunder Celestial Art, Ten Thousand Lightning Dynasty Sect!”

The seemingly simple sword strike instantly caused the sea of lightning to change. The lightning that was about to strike Qin Feng’s head suddenly changed direction. As he thrust out his sword, it actually flew back into the sky. When the lightning crossed the sky, it formed a rare sea of lightning. The sea of lightning floated in the sky, not falling. This was because the sword in Qin Feng’s hand had not yet landed.

In just an instant, Qin Feng had comprehended the third form of the Thunder Celestial Art – Ten Thousand Lightning Dynasty Sect. He realized how powerful this move was. Not only could it use one’s aura to transform into a lightning source, it could also guide the lightning source of the outside world to attack.

Rumble!

The sea of lightning in the sky began to explode. A layer of cold sweat appeared on Qin Feng’s forehead. After all, he had just comprehended the Ten Thousand Lightning Dynasty. His technique and control were still lacking. And now, he was guiding the Lightning Tribulation. In just a few seconds, Qin Feng was already struggling.

Without much time to think, he slashed down with his sword!

It was the same as when he swung his sword, simple and neat, without any fancy moves.

The power of this sword strike was extremely shocking. The sea of lightning in the sky actually fell along with the sword, but it was drawn to the outside world by Qin Feng.

Crack! Crack!

A loud noise exploded on the river bed of Zixia Spirit Vein. However, Qin Feng was in the Astral World, so he could no longer hear the violent movements. In the Astral World, the thunder clouds dissipated, and the spring breeze blew. Everything returned to normal, as if nothing had happened.

However, Qin Feng knew that everything had happened. The aura in his body became purer and stronger, and there was an additional memory of his comprehension of the Thunder Heavenly Art in his mind sea. For a moment, Qin Feng was stunned on the spot. He even forgot the joy of breaking through the sixth transformation of the Buddha Aura. He was recalling the sword strike just now. It was really incredible that a sword strike could actually trigger the sea of lightning.

“Master, the lightning array is about to collapse!” But at this time, Little Pig’s scream came from his mind.

Qin Feng immediately woke up. There were more than a hundred lightning arrays in the heavenly world, and if one of these lightning arrays exploded, it would cause a butterfly effect, causing all the arrays to instantly collapse. More than a hundred lightning arrays stored a huge amount of lightning essence energy, and it was even more violent than the lightning source that Qin Feng had just drawn away.

Qin Feng immediately used the third form of the Lightning Heavenly Secrets, and the lightning arrays on the ground seemed to have been summoned, turning into a light shadow and disappearing.

In just the time it took for an incense stick to burn, Qin Feng had drawn away more than half of the lightning essence. At this time, he was already exhausted. Although the Myriad Thunder Chao Sect Sword Style was powerful, it consumed a great deal of internal qi.

There were only twenty or so lightning saving arrays left in the heavenly world. Even if Qin Feng wanted to transfer them, he would have no strength left.

“Little Pig, if these lightning sources exploded in the heavenly world, would they destroy this place?” Qin Feng asked worriedly.

“Not really, but they will destroy the spiritual herbs and spiritual plants in the herb garden. Master can first store the important spiritual herbs or purchase energy tanks to store these lightning sources.”

“Energy trough? What is that?” This was the first time Qin Feng had heard Little Pig mention it.

Little Pig explained, “Energy trough is an all-purpose storage device. It can store any energy. In simple terms, energy star stone is also a type of energy trough. However, it can only store astral energy. There is also the fire cloud stone used by the fire cloud cannon, the radium stone used by the laser gun… These are all considered a type of energy trough.”
