Because of the experience of destroying the Demon Breeding Pool.

After Long Fei arrived at the location of this Sevenfold Heavenly Demon Cultivation Pool, he didn't have much effort, and found the core of the Demon Cultivation Pool as he wished.

Due to the power of the Demon Breeding Pool, it is extremely weird, and the strength is not strong enough to a certain extent, if it is close to a certain range of the Demon Cultivation Pool, the magic power will be sucked away by the formation power running below the Demon Cultivation Pool, resulting in a decrease in combat effectiveness.

Therefore, when Long Fei arrived at the core area of the Demon Cultivation Pool, it was rare to see the demon again, which made it more convenient for him to act.

Long Fei knew that the nutrient solution in the Demon Cultivation Pool originated from the formation that operated in the underground space, and by absorbing the magic power of the outside world, at the moment, he only needed to dive into the bottom of the Demon Cultivation Pool, reach the depths, and destroy the operation formation connected to the Demon Cultivation Pool in the space below, then this Demon Cultivation Pool would be abolished due to poor nutrient supply.

So, Long Fei, who knew the countermeasures, arrived at the edge of the Demon Breeding Pool, and without hesitation, he jumped directly into the Demon Cultivation Pool, and then began to dive down at great speed in the mysterious liquid that contained the young demons.

Long Fei dived quickly, but it still took nearly ten minutes to dive to the bottom of the pool.

The liquid in the Sevenfold Heavenly Demon Cultivation Pool, the oppressive power is more than twice as powerful as the liquid in the Demon Cultivation Pool that Long Fei encountered before, and the depth of the pool liquid is more than five times that of the original, if Long Fei's defense is not perverted enough, at this moment, I am afraid that it has been crushed into a meat patty by the powerful oppressive force released by the liquid in the pool.

Arriving at the bottom of the pool, Long Fei stretched out his palms, touched the bottom of the pool, and then manipulated the refining power of the system, turning into a silky tentacle like a hair, scattering in a net, covering the space where he was located, and at the same time, under the control of his mind, penetrated downward.

Due to the improvement of the level of the Longfei system, the refining power of the system is also rising, and the power is controlled by Longfei, and the depth of penetration is also quite amazing.

That net-like power, half a meter away from the underground space, Long Fei clearly figured out the general appearance of the real operating formation in the underground space through perception, and then without the slightest hesitation, he immediately borrowed the refining power of the system to directly refine the large array that was continuously running, continuously absorbing magic power, and providing nourishment for the demon cultivation pool.

This kind of big array, under normal circumstances, even if it is a powerful person of the 9th level of the Nirvana Realm, if he wants to refine it, it will not be possible to do it for a year and a half.

But Long Fei is not an ordinary person, he has the help of the system, and he can use the system's metamorphosis refining ability to refine it in a short time, which is equivalent to giving Long Fei the ability to destroy such a large array in a silent situation.

Minutes and seconds passed.

An hour was spent in refining.

Then, Long Fei successfully refined the operation formation of this underground space, and obtained the authority to control the power of the formation, he immediately cast a spell, so that the formation stopped running at the same time, the formation was completely sealed, and a self-destruction sub-array was set up in the formation, once there was a powerful demon, or other monks other than him, cast a spell to touch the seal, intending to lift the seal of the formation, then the sub-array would immediately operate, directly destroying this large array.

To be foolproof, Long Fei stopped and quickly left this demon breeding pool.

A day later, the young devils in the pool went berserk due to lack of nutrients, killing their companions.

Two days later, a large number of young demons died.

Then, Jiang Jinhan, the demon head who was stronger in this Seven Heavenly Demon Domain and had reached the 8th level of the Nirvana Realm, arrived at the core area of the Demon Cultivation Pool to check what was going on, only to find that the Nutrient Supply Formation of the Demon Cultivation Pool had stopped working, and he did not hesitate at all, and immediately put on protective equipment and dived into the bottom of the pool to investigate the situation.

Soon, he discovered the problem, and without the slightest hesitation, he immediately tried to release his power, forcibly tearing through the blockade of the sealing power, urging the formation to make it operate normally, and continue to provide nutrition for the Demon Breeding Pool.

However, as a result, his shot caused the formation to collapse directly and a big explosion occurred.

He could hear a dull loud bang coming from the underground space, and then he clearly noticed that the ground under his feet trembled violently, as if a large-scale earthquake had occurred, a large area of the ground was torn apart, and cracks appeared that were more than a foot wide, and the liquid in the demon breeding pool was lost in a very short time.

Jiang Jinhan, who was intent on repairing the formation and making it work, was immediately dumbfounded when he saw the scene in his sight, and exclaimed in his heart: "What is the situation? Why does the formation in the underground space suddenly have a big explosion? This incident is unusual!"

The destruction of the Demon Cultivation Pond is a very serious event for any Demon Domain.

Therefore, after this Demon Cultivation Pool was completely destroyed, Jiang Jinhan immediately began to investigate, hoping to find out the key reason for the problem in the Demon Cultivation Pool, when he inquired and checked, he learned from the mouths of the demons who guarded the Demon Cultivation Pool that before the accident, only the Demon Lord of Sheen had come to inspect the Demon Cultivation Pool.

"Sheen Demon Lord?" After receiving the exact answer, Jiang Jinhan was stunned.

After thinking that the destruction of the Demon Breeding Pool was related to Sheen, Jiang Jinhan immediately ordered everyone to guard, strengthen vigilance, and protect the scene, and hurriedly returned to the main hall to find Xi'en's traces, but he was empty.

"Where has he gone, why isn't he here now?" Jiang Jinhan said to himself.

However, after pondering for a while, he didn't bother to care about anything else, so he cast a spell on him, condensed the knowledge rune of the destruction of the demon breeding pool that was currently happening in this demon domain, transmitted it, and sent it to the upper demon domain that governed this sevenfold heavenly demon domain, the lord of the eighth layer of the heavenly demon domain, Salamander Tian.

With the destruction of the Demon Cultivation Pool, Long Fei, who was in another Sevenfold Heavenly Demon Domain, heard a system voice prompt in the sea of knowledge: "Ding, congratulations to the host for destroying the Sevenfold Heavenly Demon Cultivation Pool, and now you have a spiritual value reward of +600 trillion points!"

"Destroying a Sevenfold Heavenly Cultivation Demon Pool, you actually gained 600 trillion spirit points, which seems to be too easy to come by. Of course, the reason why I was able to succeed so smoothly is inseparable from the system's perverted ability and my own strength. ”

After listening to the sound of the system's good news, Long Fei only paused for a moment, and then continued to walk in the Seven Heavens Demon Domain controlled by the demon Delang as Xi'en, and hurried to the palace where the demon lord Delang was in charge of his practice.

Long Fei chose to see Delang because he wanted to see what Delang's face was, and afterwards he disguised himself as Delang, infiltrated the Demon Cultivation Pool, and implemented the plan to destroy Delang's control of the Sevenfold Heavenly Cultivation Demon Pool, which was relatively easy.

In fact, the relationship between Sheehan and Delang was not very good, and Delang was a little surprised to hear from his subordinates that Sheehan was visiting, but he still chose to meet Sheehan in the main hall.

"I heard that the Demon Lord Sheen is a busy man, and he is busy attacking new levels. I was unexpectedly free today, and suddenly came to my Delang Demon Domain, I don't know if the Demon Lord of Sheen suddenly visited, what's the important matter?" After the two met, Delang didn't talk nonsense, and actually went straight to the point and asked Long Fei. 9110
