The efficiency of directly using spirit stones to replenish true qi is not high, however, the amount of true qi consumed by all martial artists is not very large, and after an hour, there are martial artists who replenish true qi one after another.

Nearly eight tons of spirit stones, less than half of them were used.

Ten minutes later, all the martial artists finished absorbing the aura.

"Seniors, don't you need to make up for it?" Ling Chen asked.

"Enough. ”

Ling Chen nodded, put the remaining spirit stones into the storage ring, and said, "Then, let's start work, it's still the old rules, I'm responsible for finding it, you are responsible for digging, happy cooperation!"

In this narrow cave, there was indeed no spirit stone as big as the one just now, not even a four-ton spirit stone.

However, the spirit stones in this narrow cave were relatively dense, and all of them were mined, with a total amount of more than fifty tons!

Ling Chen couldn't close his mouth with joy, and the top martial artists were also very excited.

In less than half an hour, the spirit stones they dug out reached as many as fifty tons!

Mining spirit stones in the energy crystal mining area is indeed much more efficient than the outside, of course, on the premise that someone is specifically looking for a mark.

Whether it's mining energy crystals or spirit stones, it's too pleasant to cooperate with Ling Chen!

It was only after digging for less than half an hour, and for everyone, the consumption of true qi was almost negligible, and everyone did not rest, and continued to set off towards the next narrow cave.

Two hours later, mining in the area ended.

In the narrow cave behind, the density of spirit stones is not as good as the narrow cave that was mined first, but it is not bad, the total amount of spirit stones mined in this area is close to two hundred tons!

That is, Ling Chen has a storage ring, otherwise, if he mines so many spirit stones at one time, he can't bring them back to Huaxia City!

"Seniors have worked hard, do you want to rest?" Ling Chen asked.

"No, let's go to the next area!"

Just excavating the spirit stone, the consumption of true qi is not large, the spirit realm martial artist can mine for four or five hours in the spirit stone mining area, and for the god master, two hours of mining is not a substantial consumption at all.

Under Luo Yu's leadership, everyone entered another area.

All the centipedes, when they saw the human warriors, they all hurried to avoid them, even if Ling Chen mined all the energy crystals and spirit stones, there was not a single centipede to interfere.

Three hours later, mining in the area was over.

The number of spirit stones in this area is not as good as the previous area, which is just over one hundred and fifty tons.

However, there are more energy crystals than in the previous area, close to three tons!

So far, the energy crystals mined by the warriors of the military department in the energy crystal mining area have reached as many as six tons!

Mining a large number of spirit stones is gratifying, but mining energy crystals is the core!

The area of two people was mined in a row, and everyone stopped to replenish their true qi.

In fact, the true qi consumed by mining for more than four hours is not a big deal for the masters of seeing gods, but several powerhouses of the Mixed Yuan Realm do not want any martial artists to take risks.

More than an hour later, everyone came to the last area of the energy crystal mining area.

This area gave Ling Chen a big surprise at the beginning, the first energy crystal reached half a ton!

This is the single largest energy crystal mined by human warriors in the energy crystal mining area!

In the end, more than three tons of energy crystals were mined in this area, and the spirit stones were not bad, more than two hundred tons!

Ling Chen took stock of the harvest, the number of spirit stones was a little less than he expected, less than six hundred tons, five hundred and sixty tons, however, there were more than a hundred tons on him personally.

Coupled with the last time he mined alone, the number of spirit stones he mined on the Spirit Stone Planet alone reached as much as two hundred and thirty tons!

This is destined to be a record that has never been seen before or since!

What's even more gratifying is that the number of energy crystals exceeds nine tons, nearly ten tons!

With these energy crystals as the foundation, everyone's hearts are steady, and this batch of energy crystals is enough for Huaxia to fill the Tiankeng passage for four or five years!

The four areas of the entire energy crystal mining area have been combed through, and everyone naturally has no reason to stay anymore, they are all eager to rush back to Huaxia City, so that those warriors who stayed in Huaxia City can see their harvest this month!

"Commander, this area should be able to go out as well, right?"

Seeing Luo Yu returning the same way with everyone, Ling Chen asked.

"All areas of the energy crystal mining area can lead to the middle section of the Lingshi mining area. Luo Yu nodded.

"Then let's go straight out from here. Ling Chen proposed.

"Don't want those centipede scale armor?" Luo Yu didn't return to the tunnel.

"The centipede scale armor can't be broken for ten days and a half months, just with us, when will we be able to strip so many centipede scale armor off?"

Ling Chen grabbed in front of Luo Yu and said, "Lord Commander, let's go back to Huaxia City first, and take everyone to pick up the centipede scale armor together! Now the large centipede in the energy crystal mining area is no longer enough to pose a threat to us, so it shouldn't be dangerous to let the psychic masters come to help pick up the centipede scale armor." ”

Luo Yu groaned slightly, nodded and said, "Okay, then go out directly from here." ”

Picking up large centipede scale armor is indeed a time-consuming job, and with just 20 or so of them, I am afraid it will take a day's work.

There are still more than two hundred martial artists on the Huaxia City side, and it will be much easier for them to help pick up the centipede scale armor.

The large centipedes in the energy crystal mining area have been killed, and it is estimated that they will not dare to attack the human warriors again, besides, with the overall strength of the current Huaxia Military Department, even if the large centipedes die, they still have enough ability to protect the martial artists of the psychic realm.

Twenty minutes later, everyone left the energy crystal mining area and appeared in the middle of the spirit stone mining area.

The middle section of the spirit stone mining area is very vast, and when Ling Chen first entered the centipede mining area to mine spirit stones, he didn't mine this area to the present.

Everyone hoped to return to Huaxia City as soon as possible, the speed was very fast, and after ten minutes, they entered the passage of the Lingshi mining area, and after another twenty minutes, they left the centipede mining area.

As soon as they left the mining area, more than a dozen warriors from the military department greeted them, including Jiang Ce, Yang Shuo, and Cui Hongzhi.

"Commander, Commander, Commander, Commander, Commander, ......Commander, Commander, Commander, T

Jiang Ce and the others were relieved, their faces were full of surprise, and they greeted Luo Yu Leling and them in turn.

Luo Yu and the three great generals just nodded, and Ling Chen asked, "Why are you here?"

"You haven't come back for more than 20 days in the energy crystal mining area, and everyone is worried about your ......," Jiang Ce said in a low voice.

"What is there to worry about?" Ling Chen's face was relaxed, "Last time, I was alone, and I only had the strength of the mid-stage of seeing gods, and I could be safe and sound in the energy crystal mining area, this time there are five mixed yuan realms, and there are twenty-three gods masters, what can happen?"

In fact, this time in the energy crystal mining area, the danger is no less than last time Ling Chen was alone, but they have all returned safely, so there is no need to worry Jiang Ce and them.

"Then how do you ......?"

"Looking for energy crystals, looking for spirit stones, mining energy crystals, and mining spirit stones, it takes time. Ling Chen said calmly.

"Brother Ling, you ...... this time How's the harvest?" Yang Shuo leaned over to Ling Chen's side with a look of anticipation.

"It's okay. Ling Chen's face was light and light, "Of course, this is my humble statement, in fact, it can be said that I have returned with a full load." ”
