According to the volume of the spirit stone mine, the number of spirit stones should not be less than 1.5 million tons, but more than half of the spirit stones have been eaten by wolf-headed monsters, and now there are about 700,000 tons of spirit stones left in the entire spirit stone mine.

Compared with the energy crystals in the mine, the spirit stone is not so important, but it is by no means dispensable.

Ling Chen will not forget the hard years when the high-grade martial artists of the military department risked their lives to mine spirit stones in the centipede mining area.

Even if it is himself, he has a dark eye, but when he excavates a hundred-pound spirit stone in the spirit stone mining area, he will show off to the warriors of the military department.

After this year's National Martial Arts Competition, he threw out 10,000 tons of spirit stones, and the martial artists of the Ministry of War and the Martial Arts Association all regarded him as a god-like existence.

The energy crystal is the solution to the problem of the sinkhole, and the spirit stone is the foundation of the cultivation of the martial artists!

However, hundreds of thousands of tons of spirit stones were eaten by the wolf-headed monster, and Ling Chen couldn't help it, he didn't know that there was such a huge spirit stone mine in the depths of the centipede mining area.

However, the true qi that erupted from the body of the long-haired wolf-headed monster gave Ling Chen a great revelation.

The spirit stone of the spirit stone mine was eaten by the wolf-headed monster, but the true qi was still stored in the wolf-headed monster's qi sea!

In addition to the wolf-headed monster in the depths of the centipede mining area, there should be no other creatures, and even if there is, it is estimated that it has been wiped out by the wolf-headed monster.

In other words, the true qi stored by the wolf-headed monster in the sea of qi was almost not consumed, and the consumption was also after Ling Chen and the others came to the spirit stone mine.

Then, on average, in the sea of qi of each wolf-headed monster, there are nearly 100 tons of true qi of spirit stones!

As long as the wolf-headed monster's sea of qi is brought back, Huaxia martial artists no longer have to worry about cultivation resources!

In addition, Ling Chen slashed the wolf-headed monster with great might, and the warriors from the military department and the ancient martial arts world didn't see any of them, and without an audience, Ling Chen couldn't kill the wolf-headed monster.

The reason for this was because Cang Yanzi's defensive formation consumed a huge amount of energy, and Ling Chen couldn't afford it.

But now that there is a sea of qi from the wolf-headed monster, it won't be a big deal.

Take the corpse of the wolf-headed monster away, and then bring Luo Yu and the Deadwood Living Buddha to them!

In less than a minute, the corpses of more than five hundred wolf-headed monsters were all collected by Ling Chen into storage rings.

With the speed bonus of the Heavenly Wings, Ling Chen easily broke out of the encirclement of the wolf-headed monster group.

The wolf-headed monster group couldn't break through Ling Chen's defenses, and his speed was far inferior to Ling Chen's, so he could only watch Ling Chen fly away.

In other words, Ling Chen's ruthless killing made the wolf-headed monster already frightened, and the wolf-headed monster did not dare to intercept Ling Chen with all his strength, and Ling Chen left by himself, they couldn't ask for it.

Flying dozens of kilometers, Ling Chen landed on the ground, and did not go to meet Luo Yu for the first time.

It doesn't take long to fight with the wolf-headed monster, but whether it's a reverse training twist or an air sword attack, the consumption of true qi is too powerful, so you have to replenish the consumed true qi first, and then go to see Luo Yu and them.

The corpse of a wolf-headed monster was released from the storage ring, and with the help of the dark eye, Ling Chen easily found the wolf-headed monster's qi sea.

The wolf-headed monster's qi sea is completely different from the qi sea of the human hybrid master, it is a large balloon-shaped air bag, while the human warrior's qi sea is more similar to a virtual space.

Taking out the wolf-headed monster's qi sea, Ling Chen understood, the wolf-headed monster's qi sea was actually similar to the storage ring, it didn't seem to be big, but the capacity was beyond imagination.

The airbag on the wolf-headed monster can also be used as a storage ring?

Ling Chen tried to use his spiritual power to open the wolf-headed monster air sac and release the true qi inside.

Although he still has a large number of spirit stones on his body, using spirit stones to supplement his true qi is too wasteful, and second, it is not very efficient.

Directly using the true qi of the wolf-headed monster to replenish the true qi consumed by oneself should be faster than in the aura room.

However, using mental power to open the wolf-headed monster's airbag failed.

Try twice again, but you still can't open the wolf-headed monster's sea of qi.

Ling Chen was a little regretful, he couldn't open it with his spiritual power, so he could only use violence to open this air bag, which had no effect on the true qi, but this air bag would be destroyed, and it would be impossible to use it as a storage ring.

However, this airbag does not mean that it is useless, and in the future, he will go to the ancient martial arts world and hand it over to the dragon tooth, maybe the old man will have a way to open it.

Now Ling Chen couldn't care about breaking through the sea of qi of the wolf-headed monster, and a true qi shot out from his fingertips, hitting the middle of the wolf-headed monster's air sac.

Whew!

A fierce True Qi rushed out of the wolf-headed monster's air bag.

The true qi that rushed out would soon dissipate, and Ling Chen hurriedly ran his mental method to absorb the true qi into his meridian dantian qi sea.

"Shhhh

True Qi entered the meridians, and Ling Chen took a breath and grinned.

This is the true qi of the wolf-headed monster, the strength is not known how many times higher than the aura particles, even if Ling Chen's meridians are perfectly refined, the moment the true qi enters the meridians, he also feels a prickly pain.

Although they are all true qi, the way the wolf-headed monster combines energy particles is still different from that of human warriors.

Not only did the meridians feel pain, but the wolf-headed monster's true qi came into contact with Ling Chen's own true qi, and there was an immediate conflict, but fortunately, Ling Chen's spiritual power was strong, and he forcibly suppressed the absorbed true qi and fused with his own true qi.

While enduring the pain to replenish the true qi, he pondered and measured the usable value of the true qi in the sea of wolf head monster qi.

For a hybrid master of Ling Chen's level, any true qi could be absorbed for his own use, and it should be no problem for a late-stage hybrid master like Luo Yu.

But under the peak of the late stage of the mixed yuan, even if it is a strong person in the late stage of the mixed yuan, it is difficult to say whether he can use the true qi of the wolf-headed monster.

Enduring the pain caused by the external true qi is still secondary, the key is the conflict between the two different true qi, not the peak powerhouse in the late stage of the mixed yuan, may not be able to suppress it.

If only the peak supreme powerhouse in the late stage of the mixed yuan can use the true qi of the wolf-headed monster, then the wolf-headed monster's qi sea will be very chicken.

However, the military department has talents who can decompose the aura in the spirit stone, and it is estimated that they can also find a way to make the true qi of the wolf-headed monster used by ordinary martial artists.

Absorbing the true qi of the wolf-headed monster, the pain in the meridians and the conflict between the different true qi all made Ling Chen very uncomfortable, but the efficiency of replenishing the true qi was indeed not comparable to that of the aura room.

The true qi consumed by Ling Chen's battle against the wolf-headed monster, if it was replenished in the aura room, it would take four or five hours to say the least, but directly absorbing the true qi of the wolf-headed monster for his own use, in less than two hours, Ling Chen would return to his peak state.

Replenishing his true qi, Ling Chen unfurled his heavenly wings and flew towards Luo Yu and them.

Ling Chen went to the Spirit Stone Mine alone to fight the wolf-headed monster alone, and the rest of the mixed yuan masters stayed behind to wait for him, but this kind of waiting was even more difficult than participating in the battle in person.

Although they knew that Ling Chen would not come back in the short term, everyone still glanced in the direction of the Spirit Stone Mine from time to time.

"Hmm, there's someone over there...... Is Ling Chen back?" Yuwen Chu glanced at the sky in the distance and said in surprise.
