Of course, it was impossible for a powerful warrior in the universe to kill the ten thousand history books that contained science. He couldn't change the fate and history of others, all he had to do was change the fate of the destroyed universe …

Thus, Chen Feng's most powerful system was constantly being repaired and improved by tens of thousands of Earth's most powerful scientists. Therefore, the development of this system was immeasurable!

Moreover, these ten thousand souls were fused into the system. As long as Chen Feng was alive, the system would exist. These ten thousand souls would also exist, and the system would continue to grow stronger, evolve, and update.

At the bottom of the ocean, Chen Feng was rapidly making his way through the ocean. Because he was not used to it at the start, he was unable to catch up with the demonic energy.

Once this aura enters the water, it's like a dragon turning into a fish swimming in water.

"Rushing Dragon …" At this time, Chen Feng was familiar with the speed at which the sea was moving, and he actually used a flying sword to execute a martial skill.

Only Chen Feng could imagine that a martial skill cultivation technique combined with the Imperial Sword Technique could be used in such a way!

He spread his arms, and the Immortal-Binding Ropes flew out, tightly binding him and his clothes!

"Boom …" Weng Weng sounded. The sea water suddenly turned turbid as a powerful force burst out. Thousands upon thousands of bubbles were formed in the turbid water, constantly rising upwards!

In an instant, he stepped on his flying sword and stood low with his clothes on his back, his fists clenched as he placed them at a distance beside him.

He lowered his body and formed a bow. His body spun and his feet spun. The huge flying sword spun along with the black light.

"Awoo …" A sound of dragon's mouth rang out and waves surged at the bottom of the sea. Spiritual Energy shot out like sharp blades. In an instant, many of the Spirit Beasts in the surroundings were fleeing frantically for their lives.

This time, he definitely couldn't let this demonic immortal energy escape!

He still wanted to find treasures at the bottom of this sea, so he had to hurry and finish off this demonic immortal energy!

Immediately, the flying sword and Chen Feng seemed to have fused together!

His movements were like a mad dragon, and his speed in the water was even faster.

Even though the speed had increased, the consumption of spiritual energy was still extremely fast!

"Dragon's Twin Lock …" At this moment, Chen Feng wasn't far from reaching this demonic immortal energy!

Sometimes he was like a mad dragon, sometimes he was like a furious shark. His speed was too fast, and his movements were way too berserk!

With a wave of his hands, the immortal binding chains extended out of the seawater like two roaring evil dragons.

In the process of extension, the Spiritual Energy within the bundles of Immortal Chains continued to rotate. "Activating virus data infection …"

In the blink of an eye, Chen Feng's violent domineering aura and crazy Dao arts were going to wipe out this demonic immortal energy!

However, this demonic spiritual energy suddenly weakened!

This demonic immortal energy was becoming more and more powerful! And now, it could even split and disintegrate!

"System activated, Data Sky Eye …" At this time, Chen Feng activated the spiritual connection in his brain.

At this moment, a third eye appeared on his forehead.

On the body of this demonic spiritual energy, the data was already used!

As long as this data existed, Chen Feng could use it to track the Sky Eye. He would be able to find this demonic spiritual energy 1,000 kilometers away.

The system had more and more functions now, and it was getting easier and easier to use!

Driving their flying swords, the sound of the swords rang out as the two of them flew into an underwater canyon.

Furthermore, he was still moving downwards!

Sometimes left, sometimes right, sometimes down.

After flying for a long time, they were actually in the valley.

The spirit vein contained a powerful natural energy. After absorbing and refining it, one's realm and strength would increase and one's spirit energy would grow stronger as well.

"Feng …" Be careful. There's probably a powerful deep sea spirit beast here … " The clothes behind Chen Feng softly whispered to him.

Chen Feng also nodded his head. The deep sea canyon was currently becoming narrower and narrower, and the spirit energy was becoming denser and denser.

Chen Feng knew, he knew of this spiritual vein.

In addition, the spirit vein was much purer and larger.

A normal spirit vein was divided into one hundred year spirit vein, one thousand year spirit vein, ten thousand year spirit vein, one hundred thousand year spirit vein, and one million year spirit vein.

To be able to find a spirit vein for ten thousand years in the Spirit Cultivation World would be extremely difficult. Even after a thousand years, no one had been able to find a spirit vein for ten thousand years.

Although he couldn't find it, it didn't mean that the Spirit Cultivation World didn't have a spirit vein of ten thousand years.

As for 100,000 year spirit veins, they were only available in the Celestial Realm. As for a million year spirit veins, they were also available in the Celestial Realm. It was just that they were relatively rare.

Possessing a hundred year spirit vein could increase the amount of spirit energy that one had to painstakingly cultivate for ten years. A thousand years to increase the cultivation of one's spiritual force by a hundred years, ten thousand years to increase it by a thousand years, and so on.

Furthermore, it could increase the same lifespan. In other words, after obtaining the 100-year spirit vein, not only would one's spiritual power increase by ten years, the lifespan would also increase by a hundred years.

Some Half Immortal experts, because they couldn't ascend, used their spiritual veins to extend their lives.

However, a hundred-year spirit vein was extremely precious. If one refined it too much, the effect of the increase in lifespan would not be very good!

It's not easy to obtain a thousand year spirit vein, unless your luck is very good!

"Ten thousand year spirit vein!?" Frigid Snow, who was wearing both the clothes and the pet bar exclaimed at the same time.

Chen Feng was also shocked. The reason why this demonic energy came was to fuse with a ten-thousand-year spiritual vein to strengthen his demonic energy.

Only by having ten thousand years of sufficient spiritual energy would one be able to nurture a spirit vein of ten thousand years. If he allowed the demonic energy to fuse with his body, then this would be an incredible feat. If Chen Feng wanted to kill it, then he wouldn't have the ability to do so!

Just at that moment, they had reached the end of the canyon. However, there was a huge hole on the underwater wall in front of them.

The demonic energy had already entered, and the ten-thousand-year spirit vein was here.
