It's not only a waste of spirit stone, but also a low efficiency.

At this time, the advantage of Lingchen's perfect quenching before is reflected.

If other martial arts practitioners use the spirit stone to practice directly, they can only absorb 10% of the spirit spirit in the spirit stone. Ling Chen can at least double that. With his incomparable mental power, the efficiency of absorbing spirit spirit is almost four to five times that of other martial arts practitioners.

However, Ling Chen's own strength is too strong, even though the efficiency of absorbing aura is far higher than other Hunyuan experts, the strength recovery is extremely slow.

Nearly four hours later, Ling Chen's strength only recovered to the peak at the beginning of Hunyuan.

If Yu Wen Chu comes to challenge at this time, Ling Chen can only continue to bear Yu Wen Chu's bird spirit!

Of course, Yu Wen Chu won't disturb Ling Chen at this time. He is working with other Hunyuan experts to clean up the remains of Lingshi mine.

The Lingshi mine, which was detonated by the wolf head monster, has shrunk by more than ten times, but the remains of the mine are extremely hard. Even those who are strong in the Hunyuan realm can hardly dig up the ruins of the Lingshi mine with their bare hands.

Fortunately, everyone came with the Wulang spine. It's not so hard to dig it up as a weapon.

However, with the hardness of the remains of the Lingshi mine, it may take at least three days to dig out a passage into the mine.

The endurance of the strong people in Hunyuan is very comparable. For three days in a row, they were digging on the ruins of Lingshi mine without sleep.

Three days later, Ling Chen relied on Lingshi to provide Qi, and finally recovered to the late Hunyuan period.

There is a big difference between the later period of Hunyuan and the peak of Hunyuan, but when it comes to the later period of Hunyuan, Ling Chen feels relaxed.

Strength recovery, mental power will also be restored, finally can use the wolf monster's Qi to quickly restore strength.

Ling Chen said that he could not control the true Qi of wolf head monster at the peak of Hunyuan later period, which is for the general Hunyuan experts.

With the strength of Lingchen's meridians, Dantian and his incomparable mental strength, he should be able to withstand the impact of the wolf head monster's Qi, and also suppress the wolf head monster's Qi, but he will suffer more.

However, compared with the complete recovery of strength, what is the impact of external Qi?

More than four hours later, Ling Chen jumped up, the body's decline, has long been swept away!

At the moment when the strength returns to the peak, the first thing Ling Chen has to do is to confirm how many energy crystals are left.

He opened his eyes and scanned the past. He saw the four men from the Ministry of war and the Hunyuan experts from the ancient martial arts working hard to dig inside the mine. After three days of digging, they were very close to the inside of the mine.

Ling Chen just glanced at Luo Yu and focused on the energy crystal inside the mine.

The periphery of the energy crystal column has been blown black, which is expected by Lingchen.

Lingshi mine explosion explosion, located in the mine internal energy crystal column, it is impossible to have no damage.

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

It's an undamaged energy crystal!

Between the golden and black energy crystals, there is a layer of light yellow energy crystal more than two feet thick. This kind of light yellow energy crystal has lost a lot of energy. Lingchen doesn't know whether it can be used to block the Tiankeng passage.

The intact energy crystal column is only about five meters high, less than three meters in diameter and less than 50 tons by visual inspection!

Hundreds of tons of energy crystal, directly shrink by half!

Fortunately, the amount of energy crystals Ling Chen estimated for Luo Yu is only more than 50 tons. Now there are more than 40 tons of energy crystals left, which is not too disappointing for Luo Yu.

Determined the size of the energy crystal, Ling Chen catapulted toward the mine ruins.

Many experts have been very close to the energy crystal column, but with their excavation speed, it is estimated that it will take two or three hours to see the energy crystal. Ling Chen doesn't want to wait any longer.

"Young master Ling! Why are you here? "

In the mine ruins channel, someone found Ling Chen, immediately exclaimed.

"Your digging speed is too slow. I'll help you." Lingchen mouth should be, people have to Luoyu and Yuwen Chu side.

People are tired. They have been sleeping for three days and three nights, OK?

Results in the end, Ling Chen also think their excavation speed is too slow!

others make complaints about it, but Yu Wen Chu can't go back to it: "is the digging too slow? You don't hurt your back when you stand! You try, what kind of hardness are these mine debris! "

"Yuwen God general, I casually said, why so angry?" Ling Chen looks at Yu Wen Chu with a smile, "do you still want to give me a hand?"

“……”

Yuwen chudun, three days later, Lingchen is not the wounded soldier three days ago, Lingchen is not completely recovered, Yuwen Chu is not sure, but he can be sure, Lingchen now absolutely can abuse him!

Yu Wen Chu doesn't make a sound, Ling Chen doesn't want to compete with him, and says: "everyone, although your excavation speed is really slow, I also know that you are very hard these days. In this way, you have a rest, I'll try."It's nothing for Hunyuan masters to stay up for three days and three nights, but all of them are digging up the remains of the mine these three days. They consume a lot of Qi and mental energy. They are really tired. Ling Chen asks them to have a rest, and they are not polite.

When everyone retreated behind him, Ling Chen said, "retreat, retreat a little more."

When the crowd retreated dozens of meters, Ling Chen raised his hands, and the two true Qi shot out of the mine ruins like a hurricane!

"Reverse practice twist!"

The Hunyuan masters standing behind Lingchen have several exclamations.

Ling Chen did use the mental method of reverse practice twist, but the real Qi winch released was different.

The normal reverse training twist is the high-intensity Qi rotating alternately to crush the opponent's attack. Now Ling Chen's reverse training twist is to break the mine debris.

The highly concentrated spirit stone remains are extremely hard and firm. Even if Ling Chen uses the air sword to attack, he can only pierce a small hole in the mine remains.

However, under the high speed of the real gas winch, the hard mine debris fell off one after another.

Ling Chen's mining efficiency is much higher than the sum of dozens of Hunyuan experts!

In other words, the real Qi winch can't reach far away. In close combat, the lethality is not much worse than the air sword attack!

More than ten minutes later, the boring sound stopped, and everyone was excited. Lingchen, this is the energy crystal?

Lingchen has indeed dug up the energy crystal column, but what we see now is only the outer layer of the energy crystal column that has lost its energy.

If you dig here, you don't need to use the real gas winch. The real gas winch has great destructive power, but the consumption of real gas is also huge.

A few minutes later, a huge black pillar with a diameter of more than five meters and a height of nearly ten meters appeared in front of the public.
