After discovering the source stone mine, Chen Feng was also excited.

Although he still doesn't know how to make the source stone mine into source stone, the energy contained in the source stone mine cannot be faked.

As long as he can get the source stone mine, Chen Feng can directly absorb the energy contained in it with the help of the system, which is no different from the source stone.

The question now is how to take the source stone mine away.

It's not impossible to absorb it directly here, but the movement that makes it like that is too big, and it can easily attract the attention of the Abyss Beast.

Once it was discovered, the Abyss Beast was on guard, and it was not so easy for Chen Feng to come over again to reap the benefits.

But just when Chen Feng wanted to mine slowly, the system actually prompted again.

Bite!

Source Stone Mine Detected, Quest Triggered, Attack System!

Content: When the system absorbs the energy in the source stone mine, make sure to not leave the range of the source stone mine for two hours to help the system complete the upgrade.

Rewards: Four-Rank Treasure Chest*1, open the system energy pool.

When he saw this prompt, Chen Feng was stunned for a moment.

What is this?

The system also needs energy to upgrade?

What the hell is a system?

However, if you think about it carefully, it doesn't seem too much that the system can provide Chen Feng with such a big help, and it needs a lot of energy support.

Anyway, Chen Feng and the system are one, the stronger the system, the stronger Chen Feng will be, so completing this task will also be of great benefit to Chen Feng.

As for the energy pool mentioned by the system, Chen Feng was even more curious.

Now that the task has appeared, Chen Feng has nothing to say, so let's start directly.

Anyway, there are only three-grade earth abyss beasts here, and the combat power will not be too strong, and the fastest speed is 6000-7000, as long as Chen Feng breaks out with all his strength, he still has a great advantage in speed, and if he persists for two hours, there should be no problem.

And just when Chen Feng decided to start the mission, a terrifying energy suddenly erupted, and then the entire source stone mine began to tremble, and a large amount of energy surged from the source stone mine and entered Chen Feng's body.

But Chen Feng couldn't feel where these energies had gone after they entered his body.

With the burst of energy, the ground began to tremble, and the abyssal beasts on the ground panicked and let out a roar of rage, trying to find out who was destroying their source stone mine.

The source stone mine was underground, so the abyssal beasts quickly locked the ground and began to dig holes, and soon found Chen Feng's traces, and then surrounded them.

Seeing this, Chen Feng didn't dare to slack off, and hurriedly rushed out of the ground, relying on his speed advantage to fight the abyssal beast.

If he continued to stay underground, once he was surrounded by the Abyss Beast, Chen Feng would not even have room to dodge.

After coming to the ground, the situation was different, Chen Feng was not the opponent of so many abyssal beasts, but he could give full play to his speed advantage to fight, as long as he did not leave the range of the source stone mine and did not affect the system to absorb energy.

And after the task began, a countdown appeared in front of Chen Feng's eyes, and now only a minute has passed.

The power of the domain has no effect on the abyssal beast, but in order to maintain his combat power, Chen Feng still took the initiative to release the domain, absorbing the surrounding energy through the domain to replenish consumption, and also tried to avoid head-on collision with the abyssal beast when fighting.

Two hours is not an easy way to get through, even if Chen Feng has seen a lot of big scenes, he doesn't dare to say that he will definitely be able to do it.

Thousands of abyssal beasts felt that the energy in the source stone mine was being continuously absorbed, and they became anxious one by one.

For them, the source stone mine is something more important than life.

The Abyssal Beast can die, and the tribe can bear huge losses, but the Source Stone Mine must not be lost!

The Abyssal Beast can be regenerated after death, but if the Source Stone Mine is gone, then there is no need for the Abyssal Beast Tribe to exist, and they will also become wandering Abyssal Beasts, and it will be difficult to survive in the third layer, let alone improve their strength.

In this case, almost all of the Abyssal Beasts began to fight desperately.

Thousands of abyssal beasts that could ignore the suppression of the realm began to fight desperately, and Chen Feng's pressure suddenly became greater.

Especially when thousands of Earth Abyss Beasts formed an encirclement and began to compress Chen Feng's dodge space from the outside little by little, Chen Feng knew that a tough battle was inevitable.

In that case, let's get started!

The anger of the honest man!

The power of Jiuding!

Field Explosion!

Speed!

The four skills were displayed at the same time, and Chen Feng's combat power was significantly improved, and the source power reached 66589!

67600 source force is the minimum standard of the four products, and Chen Feng at this time is not far from this standard.

And Chen Feng's attack strength has reached 729,000, and his speed has reached 24471!

With such a terrifying attack strength and speed, against an abyss beast with only a third-grade combat power, it can easily be killed in seconds!

So when a large number of abyssal beasts surrounded him, Chen Feng showed no mercy at all, swinging his long knife and killing one abyss beast after another!

But the Abyss Beast didn't have any fear or retreat, and still fought hard and moved forward.

Moving their source stone mines is worse than killing them.

It was only after Chen Feng killed dozens of abyssal beasts that rushed over in a row that he realized how much importance the abyssal beasts attached to the source stone mine, and once again felt a huge pressure.

But the more this is the case, the more Chen Feng can't give up.

When the system publishes the task, it must have measured the difficulty of the task before giving a reward.

The four-grade treasure chest is very precious, but compared to the difficulty of the task, it is really nothing, so Chen Feng knows that the biggest reward for this task must be the energy pool.

Opening the energy pool is likely to bring about a qualitative change in Chen Feng's combat power, just like the anger system.

So no matter how difficult and dangerous it is, Chen Feng can't give up.

The Abyss Beast valued the Source Stone Mine, and Chen Feng not only valued the Source Stone Mine, but also the Energy Pool.

Since it is impossible for both sides to retreat, let's fight hard.

After killing dozens of Abyssal Beasts, Chen Feng completely entered a desperate state, and when he fought against the attacks of the Abyss Beasts with all his might, his body also began to be injured.

However, Chen Feng can exchange the recovery potion from the system mall, and the effect of using the power of the domain is better, so this injury is nothing to Chen Feng, and it will not affect the combat power at all.

With the support of the recovery potion, although Chen Feng's situation was difficult, it was not enough for him to hold on.

What's more, Chen Feng had already seen this kind of scene, and being surrounded by different species was even more small, and the long knife in his hand would not tremble in the slightest.

However, when Chen Feng was fighting with the Abyss Beast, the Three-Headed Snake and the Sky Shaking Tiger happened to come to the vicinity of the Abyss Beast Tribe!
