Directly using spirit stones to supplement true qi is not only a waste of spirit stones, but also inefficient.

At this time, Ling Chen's previous advantages of perfect tempering were reflected.

If other martial artists directly cultivated with spirit stones, they could only absorb one percent of the spiritual energy in the spirit stones, and Ling Chen could at least double it, coupled with his unparalleled spiritual power, the efficiency of absorbing spiritual energy was almost four to five times that of other martial artists.

However, Ling Chen's own strength was too strong, even though the efficiency of absorbing aura was far higher than that of other hybrid masters, his strength recovered extremely slowly.

Nearly four hours had passed, and Ling Chen's strength had only returned to the peak of the early stage of the Mixed Yuan.

If Yu Wen Chu came to provoke at this time, Ling Chen could only continue to endure Yu Wen Chu's bird spirit!

Of course, Yuwen Chu would not bother Ling Chen at this time, he was working with other mixed yuan masters to clean up the wreckage of the Spirit Stone Mine.

The spirit stone mine that was detonated by the wolf-headed monster has shrunk by more than ten times, but the wreckage of the mine is extremely hard, even if it is a strong person in the Mixed Yuan Realm, it is difficult to dig up the ruins of the spirit stone mine with bare hands.

Fortunately, everyone came with the centipede backbone, and the centipede backbone was used as a weapon, and it was not so laborious to dig it up.

However, with the hardness of the remains of the Lingshi mine, I am afraid that it will take at least three days to dig a passage into the interior of the mine.

The endurance of the powerhouses of the Mixed Yuan Realm was very comparable, and for three consecutive days, they dug on the ruins of the Spirit Stone Mine without sleep.

Three days passed, and Ling Chen completely relied on the spirit stone to provide his true qi, and his strength finally recovered to the late stage of the mixed yuan.

There was a world of difference between the late stage of the mixed yuan and the peak of the late stage of the mixed yuan, but when he returned to the late stage of the mixed yuan, Ling Chen suddenly felt relaxed.

The strength is restored, and the spiritual power is also restored, and you can finally use the true qi of the wolf-headed monster to quickly recover your strength.

Ling Chen said that he couldn't control the true qi of the wolf-headed monster at the peak of the late stage of the mixed element, which was for the average mixed yuan master.

With the strength of Ling Chen's meridian dantian and the incomparably powerful spiritual power, he should be able to withstand the impact of the wolf-headed monster's true qi, and he could also suppress the wolf-headed monster's true qi, but the suffering would be greater.

However, compared to the complete recovery of strength, what is the suffering of the impact of foreign true qi?

More than four hours later, Ling Chen jumped up, and the decline on his body had already been swept away!

At this moment when his strength returned to its peak, the first thing Ling Chen had to do was to confirm how many energy crystals were left.

The dark eye opened, and when he glanced at the past, he saw that the four people of the military department and the mixed yuan masters of the ancient martial arts world were all struggling to dig into the inside of the mine, and after three days of excavation, they were very close to the inside of the mine.

Ling Chen only glanced at Luo Yu and them, focusing on the energy crystals located inside the mine.

The periphery of the energy crystal pillar was all blown black, which was expected by Ling Chen.

Lingshi Mine Explosion-Explosion, the energy crystal pillar located inside the mine, it is impossible to have no damage at all.

Through the outer layer of the energy crystal pillar, Ling Chen finally saw a touch of gold inside the pillar.

That's an energy crystal that hasn't been damaged yet!

Between the golden energy crystal and the jet-black energy crystal, there was a layer of pale yellow energy crystal more than two feet thick, this pale yellow energy crystal, the energy had lost a lot, and Ling Chen didn't know if it could be used to block the sinkhole passage.

The intact energy crystal pillar is only about five meters high, less than three meters in diameter, and less than fifty tons by visual inspection!

Hundreds of tons of energy crystals have shrunk by half!

Fortunately, the estimated number of energy crystals that Ling Chen gave Luo Yu to them was only more than fifty tons, and now there were more than forty tons of energy crystals left, so it would not disappoint Luo Yu and them too much.

Determining the size of the energy crystal, Ling Chen dodged and ejected towards the ruins of the mine.

The masters were already very close to the energy crystal pillar, but with their excavation speed, it was estimated that it would take two or three hours to see the energy crystal, and Ling Chen didn't want to wait any longer.

"Ling Gongzi, why are you here?"

In the passage of the mine ruins, someone found Ling Chen and immediately exclaimed.

"You're digging too slowly, I'm here to help. Ling Chen's mouth responded, and the person had already arrived at Luo Yu and Yu Wenchu's side.

Everyone is tired, they have been sleepless for three days and three nights, okay?

In the end, Ling Chen thought that their excavation speed was too slow!

The others just complained in their hearts, but Yu Wenchu had to go back: "The excavation speed is too slow? You kid doesn't have a backache when you stand and talk! You come and try what kind of hardness these mine wrecks are!"

"Yuwen Divine General, I'll just say casually, why are you so angry?" Ling Chen glanced at Yuwen Chu with a smile, "Do you still want to make a move on me?"

“......”

Yuwen Chu suddenly swallowed, three days have passed, Ling Chen is no longer the wounded soldier three days ago, whether Ling Chen has fully recovered, Yu Wenchu is not sure, but he can be sure that Ling Chen can definitely abuse him casually now!

Yuwen Chu was silent, and Ling Chen didn't want to compete with him, and said, "Everyone, although your excavation speed is indeed slow, I also know that you have been working very hard in the past few days, so you can rest, and I will try." ”

Three days and three nights of sleepless rest is nothing to the mixed yuan masters, but everyone has been digging the wreckage of the mine for the past three days, and the consumption of true qi is a lot, and the consumption of spiritual power is also large, so they are really a little tired, Ling Chen asked them to rest, and they are not polite.

After everyone retreated behind him, Ling Chen commanded again: "Retreat, retreat a little more." ”

After everyone retreated a few dozen meters, Ling Chen raised his hands, and two rays of true qi shot out towards the ruins of the mine like a hurricane!

"Reverse twisting!"

Several of the mixed yuan masters standing behind Ling Chen exclaimed.

Ling Chen had indeed used the mental method of reverse practice twisting, but the True Qi winch released was different.

The normal reverse training winch is a high-intensity true qi staggered rotation to achieve the purpose of crushing the opponent's attack, and the reverse training winch that Ling Chen has now cast is to break through the wreckage of the mine.

The highly concentrated spirit stone wreckage was extremely hard and sturdy, even if Ling Chen used an air sword to attack, he could only make a small hole in the mine wreckage.

But under the high-speed twisting of the True Qi Winch, the hard mine wreckage fell off one after another.

Ling Chen's mining efficiency alone is much higher than that of dozens of mixed element masters combined!

That is to say, the True Qi Winch can't reach far, and in close combat, the lethality is not much worse than the air sword attack!

After more than ten minutes, the annoying wringing sound stopped, and everyone suddenly became excited, Ling Chen has already dug up the energy crystal?

Ling Chen had indeed dug up the energy crystal pillar, but what he saw now was only the outer layer of the energy crystal pillar that had lost its energy.

Digging here, there is no need to use the True Qi Winch, the True Qi Winch has a huge destructive power, but the consumption of True Qi is also huge.

Switching to an air sword attack, a few minutes later, a jet-black giant pillar with a diameter of more than five meters and a height of nearly ten meters appeared in front of everyone.
