As the entrance to the underground vein, the value of the energy crystals here is limited, far from being comparable to the core. Even if there are occasional crystals that are of the highest grade, they have long been poached by Arx and others.

Lin Fei did not stop, and led the crowd to approach the depths of the interior.

As they progressed, the size of the Soul Eaters they encountered grew from the size of a cockroach to the size of a baby's palm to the size of an adult's palm.

And someone under Lin Fei's command also took out a flame thrower that simulated solar fusion, and directly came to open the way with flames, so that Lin Fei's road ahead was unimpeded.

Until the last part of the passage, everyone turned into diligent miners, wielding pickaxes or their own weapons, and struggling to mine energy crystals and various derivative ores.

"Dangdangdang—"

For a while, the crisp sound was endless, as if striking iron.

The most astonishing thing is Lin Fei's mining method, which is to blast the solid stone away with his bare hands, or fist or palm, simple and violent, simply direct.

The key is that his strength is extremely skillful, even if the solid rocks around him are shattered, the energy crystals in it are still undamaged, and there is no crack that causes energy to leak out.

Obviously no pickaxe was used, but it was ridiculously efficient.

Lin Fei did not dig left and right, but concentrated on advancing towards the center of the ore vein. In his opinion, the energy contained in the crystals here is too low, and most of them are sub-grade goods, and only about one percent are low-grade energy crystals, which can be regarded as the standard cultivation resources of the lower spirits.

Even these low-grade energy crystals also have many traces of being gnawed, tattered, pitted, and some holes that are transparent before and after, or simply there are adults, wriggling strip larvae, and spherical eggs in a piece of crystal.

Although the process was boring and monotonous, fortunately nothing unusual happened. Unlike last night, when life and death were hanging by a thread, it was a great happiness for everyone to be able to obtain cultivation resources so easily, and it made them full of energy.

It's just that as time goes on, the condition of the lower spirits becomes more and more worrying.

Gu Xiaoyu, a martial arts monk, has a relatively strong physical body, but it is good to say that the arcanists have gradually begun to have nosebleeds, and even have symptoms such as inflammation and fever, like the immune system is at war with the invaders.

The lower spirits of the Arcane Clan and the Multi-Eyed Clan couldn't hold on, their physical strength was seriously reduced, and their efficiency was worrying.

"The lower spirits all went out and waited outside. Lin Fei gave the order, and all the subordinate spirits present were immediately relieved and hurriedly retreated.

Ah Xing was engaged in scientific research in the camp, and with the new captives, there were only three median spirits here, and they were collecting energy crystals along with Lin Fei.

As they progressed deeper into the veins, the radiation they felt became more and more intense, and even the skin of the three median spirits began to fester, oozing pus.

And the spirit eating insects that appeared were also more powerful, not only devouring crystals with more energy, but also showing a certain degree of mutation, and the combat power of a single body was comparable to that of the lower spirits. The Gauss bullet hit them, making a "dangdang" sound, and bounced in all directions.

Fierce orange-red light continued to catapult in the passage, and those spirit eating insects rushed fiercely to kill, causing a lot of trouble to everyone's mining.

With the exit of the three median spirits, only Lin Fei was left to insist.

According to a rough estimate, he has mined more than 4,000 catties of sub-grade crystals and more than 400 catties of low-grade crystals. Not to mention the high-grade crystal, there is not even a medium-grade crystal!

As for other special ores, Lin Fei was even more disdainful. It's just that there may be people under your command who can build weapons and armor that can be used, and can provide the "scientific research team" with various special elements that they need, and they may or may not be able to work wonders.

Even if it is a non-grade crystal, if there are many of them, it can still provide the energy consumption of technological creations, right?

So he didn't let it go.

Lin Fei killed a few mid-level spirit level bugs, and suddenly felt a burst of warmth in his nasal cavity, and when he touched it, he actually had a nosebleed.

The eighth layer of the upper spirit can't stand it?

Lin Fei sighed secretly in his heart, this Arcane Clan's physical body was really weak, and it seemed that he had to devour the life factor that strengthened his physical ability as soon as possible.

He put away the corpses of several spirit eaters, and rushed out in a cheetah-like manner, quickly rushing out of the passage.

At this time, the sun is setting in the west, and it is about an hour before dark.

"Let's go!" Lin Fei spat out a word and led the crowd back to the camp.

As early as in the morning, the four first-rank officials of Ao Zongping had already hardened their heads and led their subordinates to the Scarlet Worm Ridge.

The Arcane people were scurrying around the jungle like headless flies, trying to find Lin Fei's traces - to quickly arrest him and leave this dangerous place.

This is almost unanimous in their hearts.

But unfortunately, the location where they entered the Scarlet Insect Ridge was different from Lin Fei's, and they had no clue until now. Seeing that the night was getting closer and closer, Ozunping and the others panicked.

"It's almost night, or come back tomorrow morning?"

"What are you kidding? The scope of the prince's divine consciousness is so vast, once we leave the Scarlet Worm Ridge, it will inevitably be known to him! I'm afraid that if we boast about Haikou and retreat halfway, what awaits us is not as simple as demotion, copying our homes, and distributing them to the Southern Wilderness!"

"Ao Sanniang is right, let's keep looking, even if it is to stay overnight here. The four of us are walking together, and as long as we don't provoke the existence at the top of the pyramid, there should be no danger. ”

After deliberation, the four first-class officials decided to stick to it.

Finally, after walking an extremely wide distance, they came to the mushroom forest that had been destroyed. The devastated and desolate scenery here is a testament to the fact that there was a terrible war not long ago.

Ao Zongping and the others were immediately overjoyed, thinking that this was very likely to be related to Lin Fei, and began to investigate the scene.

Fingernail-sized shards of arcane spaceships, dried blood, footprints of creatures of all races, marks and slime from eight tentacles, fragments of masks of black iron......

All kinds of signs pointed out that Lin Fei had fought a big battle with unknown forces here.

"If we continue to investigate, we should not be far from him!" Ao Sanniang sneered, a flash of resentment flashed in her eyes.

At the same time, Lin Fei and the others had already returned to the camp.

He handed over all the energy crystals that were not of the same grade to Ah Xing and asked him to use them.

As for the distribution of low-grade crystals, those who work more get more, and they all send them down, leaving no one for themselves.

Lin Fei sat down to eat dinner, and was thinking about tomorrow's arrangements, when he saw an Arcane Clansman on duty hurriedly jumping down from the big tree, and said urgently: "Little Marquis, something is wrong! Ao Zongping and they are coming this way!"
