Compared to the radiation energy that Qi Lin absorbed on his own, the energy contained in the emerald green crystal obtained from the juvenile body of this monster was obviously much purer, and a soybean-sized one could provide so much energy for the concentrating vortex.

Qi Lin suddenly felt very unhappy, such a weak young body can dig out such a precious crystal, then the big guy who was salted by himself and dying on it, there must be a crystal in his body that is not known how many times larger, if Qi Lin Qi Lin can get that crystal, he will definitely be able to raise his evolutionary level to the fourth level.

But now let alone getting that crystal, even if Qi Lin wants to return to the ground, it is still a problem.

However, there were so many young beings in this underground cavern, if Qi Lin could kill all of them, then the purification crystals obtained would also be a number that could not be ignored.

However, only the last sixteen rounds of the 2.5mm electromagnetic bullets used by Gauss's pistol remained, and there were sixty or seventy monster hatchlings in the entire underground cavern, and in order to kill all of them, each bullet would have to kill at least four or more larvae—which was obviously impossible to do.

"Not enough bullets...... There are no other weapons...... Qi Lin casually grabbed a piece of bituminous uranium ore the size of an egg and pinched it in his hand, and at this moment, he suddenly remembered the scene he had seen before-

The pile of ore occupied by the weaker and low-status larvae is often plundered by the stronger and higher-status larvae around them - the relationship between these larvae is definitely not as harmonious as Qi Lin imagined, and the place of these ores is divided into piles and piles, it is very likely that if these larvae are put together, they will immediately compete for resources and kill each other.

Just like those heirs in a big family fighting each other for the inheritance of the family, at this time, any brothers and sisters, any brotherhood, are all just a joke.

But how did Qi Lin want to bring these young creatures together like this? Judging from the current situation, these young organisms will not easily leave their own territory if they do not eat up their pile of "ore", even if they want to rob their companions' resources, they will only stretch out their tentacles to fish for one or two pieces of ore scattered down, and they will definitely not give up their own share for this reason, and kill other young organisms on their territory.

And if Qi Lin rashly intervened, not only would they not be able to let the two young organisms fight each other, but they would instead turn the spearhead and first talk about Qi Lin, an alien "invader", to solve it.

So what can be done to make these young creatures fight each other......

Glancing at the ore in his hand, Qi Lin suddenly thought that the reason why these young creatures were unwilling to leave their territory easily was because just one or two ores were not attractive enough for them.

So, what if you replace it with that emerald green high-purity crystal?

If you want to condense such a purified crystal, no matter how you look at it, you have to absorb several piles of ores!

……

……

Qi Lin slowly approached the other lone larvae, and after killing it with two electromagnetic bombs, he once again used ceramic fragments to pick out the purified crystal in its body, resisted the desire to absorb it, looked at the densest place where the larvae gathered, and threw the crystallization hard!

The juvenile reactions of these monsters were far faster than Qi Lin imagined, and before the crystals landed, the tentacles of several juveniles around them stretched out and fought in mid-air!

For a while, the small half of the underground hollow larvae were caught in a melee, hundreds of tentacles were entangled, poked, and cut each other, and every second there were broken tentacles falling to the ground, and the emerald green purification crystal also changed hands several times, and almost every larvae that grabbed the crystal body would be attacked by several other larvae at the same time.

Compared to the adult monster above, these young creatures are simpler in their thinking and more cruel in their actions.

The cannibalism lasted for about half an hour, and more than twenty larvae participated in the battle, and in the end, only one of them won and succeeded in taking the emerald green crystal for himself, while more than half of the other larvae were killed by their own companions, and the remaining ones were also scarred, with almost all of their tentacles broken, and they were dying in a corner.

The winning larvae swallowed the Purification Crystal, and then squirmed towards the corpse of the nearest larvae—apparently well aware that there was another Purification Crystal within the corpse of its companion.

It's just that at this time, a silent electric light suddenly flashed in the dark underground space, and the young body that was already covered with scars was directly broken into two pieces!

Qi Lin, who had been watching the entire war, walked out of the dark corner, cut off the remaining few larvae from the ceramic shards and bone blades, and then dug out the purified crystals in their bodies in the same way and threw them to the place where the other larvae gathered......

The fight between the young broke out again......

Three hours later, there was no longer a living juvenile in the entire underground cavern, and in front of Qi Lin, there were sixty-five emerald green crystals neatly stacked.

The smallest of these crystals is only about a grain of rice, and the largest one is almost the size of a quail egg - that larvae was originally the strongest one in this group of larvae, with a body length of nearly three meters, Qi Lin used six 2.5 mm electromagnetic bombs in order to kill it, and this larval still waved the tentacle more than ten meters long until the last moment before death, piercing the wrist of Qi Lin's left hand.

After briefly treating the wound on his left wrist, cutting out the necrotic tissues, applying medicine, and bandaging, Qi Lin focused on the pile of crystals in front of him.

If a soybean-sized crystal can provide about 200 points of energy, this batch of crystals is just enough for Qi Lin to push the energy reserve of the concentrating vortex to a critical point.

At this stage, players who have reached the fourth-level evolution level in the entire wasteland world are definitely rare, as for the fifth-level evolutionaries, there may be so many existences, but Qi Lin has never seen them with his own eyes, and he has not even heard the rumors about the fifth-level evolutionaries.

To create a Level 5 Evolver, you need a B-grade serum, and B-grade serum, only a terrifying creature like the King Blood Dragon Lizard that can destroy a city has an extremely low chance of dropping.
