For this parallel excavation, Loren moves more quickly, almost as fast as a person walking on the ground.

At this moment, the two energy-absorbing crystals he brought were both idle, and the last time one had absorbed Kunna's negative energy, and after a few days, it had transformed this negative energy into energy that Luo Lun could absorb and use.

In fact, Luo Lun didn't know how much negative energy this energy-absorbing crystal could absorb, and this time was just an opportunity to experiment.

Of course, he has feelings for his classmates, but Luo Lun learned through the knowledge graph that there are only two ways for the negative energy born after death to evolve, one is to change into ghosts or resentful spirits, unable to retain memories, and wander aimlessly in the world from then on, and the other is that this negative energy enters another strange space, which is called "hell".

In any case, the transformation into a ghost or even a more powerful resentful spirit is just another form of powerful negative energy, and there is no essential difference for an alchemist. And what "hell" is, Loren doesn't know, or maybe it's just a place worse than being a ghost.

This leads to Luo Lun not having any guilt when absorbing the negative energy of these classmates.

Once he was sure that the safe house was already above his head, Loren swung his golden shovel and began to dig up, and soon touched the heavy stone slab on the floor of the safe house.

There wasn't a single yellow lice near the sand, but Loren was still careful when he used his object control skills to lift the thick stone slabs.

Standing in the safe house, feeling the large amount of negative energy in the vicinity, Loren took a breath and took out the two energy-absorbing crystals, while holding the catalytic flash in his heart.

Because the dead students have not been in a long time, even the ghosts in the form of Kunna have not yet formed, and soon these negative energies have been collected and sucked into these two energy-absorbing crystals.

After about a few minutes, you can see that the inside of the energy-absorbing crystal continues to change color, first transparent, then gray, more and more, until the whole crystal is filled, and finally all slowly turns from gray to black, and after reaching a thick ink color, it finally no longer absorbs negative energy from the outside world.

At this time, Luo Lun could feel that there was still a little negative energy that had not been absorbed, but at present, he had reached the limit of the energy-absorbing crystal, and he could barely do it. Luo Lun had to put away the energy-absorbing crystal, and then excitedly came to the corpses of several combat side students, squatted down, and picked up the kinetic energy suits on their bodies.

The Green Melt's attack method is to break through the helmet and enter, so the rest of the body parts of the suit are intact except for the damage to the helmet.

Luo Lun counted them, there were a total of seven corpses of the combat side students, that is, there were seven sets of kinetic energy suits, and he peeled off these seven kinetic energy suits at an extremely fast speed, and threw them into the space ring along with the tattered helmet. Immediately, he took out a thick blanket from the daily necessities he was carrying in the ring, lined up the seven people, and gently covered it.

Originally, there was also a kinetic warrior named Hume, but he was possessed by the green melt cockroach, and his body was currently in a ruined city far away, and he could no longer rush over to get the kinetic suit.

After doing this, Luo Lun was about to leave from the underground passage, when suddenly he looked surprised, turned his head sideways, and used his eye-hiding skill in a certain direction.

Under the filtering of the hidden eye, not far from the safe house, two lonely rays of negative energy appeared there, fluttering, sometimes scattering, sometimes gathering again.

One of the faces of negative energy had already gathered some of it, and the outline of the facial features could be roughly distinguished, and through the extremely detailed observation of the hidden eyes, Loren quickly concluded that the negative energy was Charles.

As if he had guessed something, a hint of complexity surged in his heart, and Loren quickly jumped into the underground passage and left.

Before entering the improvised underground space, Loren used the same technique to make a kinetic energy wave container again, and input some of the remaining kinetic energy from the land chariot into the wave container.

Then he took out the first kinetic energy wave container, opened it and took out the Yan Ghost Mandala that had been folded into three sections, and quickly closed the clasp lid again, and incorporated this wave container into the space ring again.

Approaching the green melt cockroach that frightened the Yan Ghost Mandala for a long time, although this guy had been released, he was still trembling, and the whole petal was harvested into a flower bone, but its rhizome was immediately rooted in the sand after it came out.

"Do one thing for me, and I'll separate you from the green cockroach." Loren patted the newly-made, slightly larger wave container at his feet.

Yan Ghost Mandala immediately stretched out its flowers, and let out a burst of flattering laughter: "Master, I suddenly found that you are so handsome, your figure is so charming, and your voice is so magnetic, especially when you smile, the corners of your mouth are slightly raised......

"Don't play these tricks on me!" Luo Lun interrupted it with a sneer, "Promise me to separate it from the green melt cockroach and put it into a different wave container, if you don't promise me, I will send you back immediately." ”

"I promise!" Yan Ghost Mandala smiled awkwardly, and the grimace on the stamen became more and more infiltrating.

"Okay." Loren lowered his voice, "This is not something to do right away, you are trying to accumulate neurotoxins in your body from now on, the maximum amount of stockpiling. I want you to play a super fantasy world with me like never before. ”

"I'm rubbing, so exciting?!" The guy shook his branches excitedly.

……

After returning to the underground space, Luo Lun seemed to have turned back into an ordinary student, never leaving here again, and did not make any unusual moves.

Every day, he either took care of the wounded with other students, or sat there alone in a daze, but in fact, he had already entered meditation, increasing the amount of magic energy in his body little by little.

Until the third day of hiding in the underground space, Luo Ren's magic energy reached the level of 15 units, and this number could already impact the "magic ability field".

However, Loren still decided to wait until he returned to the reserve to find a time to hit this node.

By the fifth day of hiding, the swarm of yellow lice on the ground had already gone to all directions, only a small part was wandering, and the crawling range was basically far away from this place.

Loren didn't seem to have any intention of going out to investigate, just sitting in a "daze" every day, or taking care of the wounded, and then chatting with Tarri, Ronda, Guboda Hikari and others, or simply squatting there to watch Fanny dissect and study the brain nuclei of the yellow lice and the sand devil.

On the seventh day, when the students' minds were obviously uncontrollable and became extremely anxious, and seeing that the food was about to run out, Luo Lun's mood suddenly became very happy, as if something great had happened.

On this day, in the sky not far from the rock formation, several small black dots appeared, and the speed was extremely fast, gradually showing a tough streamlined shape, which was the mad shadow fighter belonging to the Yida Military Region.
