Yang Qian, who went and returned, hid behind a big tree hundreds of meters away, which happened to be the extreme of his mental power detection range, Yang Qian used his spiritual power to observe the movements of the three mutant beasts, and then he was disappointed to see that the three mutant beasts did not tear each other apart, but divided the corpses of the second-order mutant flower snake and the second-order mutant ape and left, leaving only a large blood stain in the field.

"It seems that the mutant beast also has a lot of wisdom, and it is a pity to know that it is necessary to avoid needless tearing and killing!" Yang Qian secretly regretted in his heart that he couldn't be a fisherman again.

Although the mutant beast also has a certain amount of wisdom, it is far inferior to humans, the mind of the mutant beast only has the idea of hunting, devouring, and evolution, and the mental fluctuations are mostly based on killing, if a weak mutant beast encounters a mutant beast that is stronger than it, most of them will be devoured and become the nutrients for the other party's evolution.

The reason why Yang Qian left was because he sensed that several powerful biological auras were approaching, and the reason why he turned back was because he wanted to see the scene of them tearing each other apart and fighting, so that he would have a chance to take advantage of it, and maybe there would be a few more second-order brain crystals in his hand.

However, these three mutant beasts formed a three-legged momentum, they had scruples about each other, they did not do it immediately, but quickly left after dividing up the corpses, if they met in pairs, they would kill each other at the first opportunity to continue to evolve, but the current situation with their wisdom also knew that now was not a good time to tear up, once the fight would let the other party take advantage, simply stop.

This misty forest is like a huge fish tank, and the many mutant beasts living in it are like small fish, where big fish eat small fish are staged all the time, weak mutant beasts are difficult to survive, and powerful mutant beasts will not worry about food, they are guarding against mutant beasts of the same level.

Since this forest is like a large fish tank, then Yang Qian plans to act as a fisherman in the fish tank, and after leaving here, he will start looking for the traces of mutant beasts, this forest is so vast, and there are really many mutant beasts living in it, in order to evolve into a more advanced existence, mutant beasts are tearing and devouring each other all the time, which also makes it easy for Yang Qian to find many mutant beasts tearing and fighting.

At this time, Yang Qian played the role of a fisherman very well, every time the mutant beasts were dying of injuries in the battle, Yang Qian appeared very appropriately, and then gave the mutant beasts a thunderous blow, grabbed their blood and brain crystals and quickly left.

However, Yang Qian always encountered only some weak first-order mutant beasts, and the harvest was not very large, after all, second-order mutant beasts were also powerful existences in this forest, and they had already taken great luck when they encountered second-order mutant flower snakes and second-order mutant apes before.

After half a day, the brain crystals in Yang Qian's pocket were heavy, except for the first two second-order brain crystals harvested in this half day, the remaining eighteen brain crystals were only first-order, but Rao was so Yang Qian was also very satisfied, you must know that it is not easy to hunt first-order mutant beasts outside, and now Yang Qian can obtain so many brain crystals without too much hard work, if people outside know it, they will definitely be envious and jealous.

Generally speaking, the physique of mutant beasts is much stronger than that of humans, which means that mutant beasts of the same level are stronger than human evolutionaries and evolved zombies, and it also means that the evolutionary energy contained in the brain crystals of mutant beasts is larger than that of evolved zombies.

Yang Qian has been picking up leaks for half a day, attacking and killing seriously injured mutant beasts, and now half a day has passed, and it is now the dusk of the day, Yang Qian, who is still in the forest, finds that the light around him is getting more and more dim, even in the misty forest wrapped in white fog during the day, the light is not very bright, maybe it won't be long before the sky is completely dark, and the forest will be so dark that you can't see your fingers.

The night was about to fall, and Yang Qian had cut off the idea of continuing to search for the mutant beast, but flew to the sky above the misty forest and found a mountain peak that had just broken through the height of the white mist.

Yang Qian gently landed on the top of the mountain, the top of this mountain is a flat place, there are a few larches growing on it, it looks a little bare, the afterglow of the setting sun is sprinkled on the rolling white mist, the red mist rolling has a unique beauty.

Yang Qian sat cross-legged on the top of the mountain and looked at the sunset, letting the warm sunlight sprinkle all over his body, bathed in the fiery sunlight, Yang Qian felt that the fire ability in his body was trembling, at this moment the fire element in the air was the most intense, Yang Qian wanted to absorb the fire element in the air, but found that there seemed to be an invisible barrier in his body, unable to absorb any energy between heaven and earth.

"It seems that my realm is not enough, I can't absorb the elemental energy in the air to strengthen myself, and I can only slowly recover after each foreign energy consumption, or rely on brain crystals, but this seriously restricts the durability of combat power."

Although he couldn't absorb the fire element to strengthen his own fire-based ability, he could take advantage of the sunset at this moment to feel the true meaning of the flames, Yang Qian stared at the sunset, and condensed into a fiery red planet in his eyes.

With fire, there is light and warmth between heaven and earth; With fire, there will be civilization in the world; With fire, there will be ashes. Fire represents creation and destruction, and fire can both create and destroy everything.

"Creation and destruction!" Yang Qian muttered.

Yang Qian stretched out his palm, a wisp of flame jumped in the palm of his hand, and as his mind the flame began to change various shapes in the palm of his hand, the flame changed back and forth between various objects such as matches, burning sticks, bullets, etc., at this moment Yang Qian understood a lot about the true meaning of flames.

After dissipating the flames, Yang Qian took out two second-order brain crystals and fused two huge evolutionary energies into every part of his body, and Yang Qian suddenly felt that his strength had improved a little.

Yang Qian is still in the second-order realm, as long as he does not break through the second-order and become a third-order powerhouse for a day, then the second-order brain crystal will always have an effect on him, if Yang Qian has a sufficient number of second-order brain crystals, he can improve his strength to the peak of the second order in a short period of time, but even if there is Yang Qian, he will not do this, the improvement of strength should be accompanied by the experience of blood and fire, and it is not a good thing to improve his strength too quickly, besides, Yang Qian does not have so many second-order brain crystals.

After the two second-order brain crystals were exhausted, all that was left was the first-order brain crystals, and the improvement in his strength was minimal, but Yang Qian still had the Gene Divine Tree and the Strength Divine Tree in his body, he felt that these two Divine Trees were still in the process of growing, and they were not yet in full form, and the evolutionary energy was the nutrients for their growth, although Yang Qian did not need the first-order Brain Crystal, but he could inject the evolutionary energy in them into the two trees.

After a while, more than a dozen streams of energy were injected into the two trees, and the Power Divine Tree seemed to have grown slightly taller, but the Genetic Divine Tree still hadn't changed, perhaps because this energy was too low-level.

The next day, Yang Qian continued to wander in the forest, looking for seriously injured mutant beasts to kill, and gradually he figured out the distribution law of mutant beasts in this forest, and also began to kill some weak mutant beasts, and a day later, he had twenty more first-order brain crystals in his pocket.

On the third day, Yang Qian decided to continue to go deep into the forest, the mutant beasts here were too weak to meet Yang Qian's needs, if he could kill a large number of second-order mutant beasts or even third-order mutant beasts, then Yang Qian's strength could soar like a rocket.

The width of the primeval forest in the Great Xing'an Mountains is two or three hundred kilometers, and the range of Yang Qian's previous activities is only twenty or thirty kilometers outside the forest, but after fifty kilometers deep into the misty forest at this moment, the sound of the roar of the ape and the tiger sometimes sounds in his ears, and the mutant beasts here are also stronger, and the first-order mutant beasts are already very rare, and most of them are second-order mutant beasts.

Yang Qian had seen a group of mutant wild boars before, there were three second-order mutant wild boars in it, and the rest had also reached the first-order realm, this group of wild boars was rampaging through the forest, and sometimes it was directly broken when encountering small trees.

Yang Qian held his breath and didn't dare to move, and only breathed a sigh of relief when the wild boar herd was far away, and secretly sighed that this forest was really very dangerous, although Yang Qian could easily win by single-handing a second-order mutant beast, but he couldn't parry it when there were too many of them.

Yang Qian found that the mutant beasts here were all groups, and each mutant beast was led by a second-order leader, which also meant that it was much more difficult for Yang Qian to start, but if he could kill a group of mutant beasts, the harvest would be huge.

"Damn, the mutant beasts here are already so powerful, could it be that there will be mutant beasts beyond the third order if you go further inside?" If this is the case, Yang Qian has to think carefully about whether to continue to go deeper, but since he is here, he still has to find an opportunity to kill the powerful mutant beast to obtain brain crystals.

Mutant beasts have territorial awareness, powerful mutant beasts occupy one side, and other mutant beasts cannot enter its territory without authorization, otherwise it will be a provocation to it, Yang Qian's aqueductive aura is like a ghost in the forest, and after a while, he arrived outside a waterhole, the fog here is a little lighter, even with the naked eye, you can see a few hideous giant crocodiles lying in the waterhole.

The shortest giant crocodile is five meters long, the longest one is ten meters long, the ten-meter giant crocodile is surrounded by a group of crocodiles, Yang Qian felt a dangerous smell on it, indicating that this giant crocodile is comparable to his strength, or even stronger, the water element above the waterhole fluctuates from time to time, making Yang Qian guess that the giant crocodile should be able to control the water element.

Yang Qian couldn't find the opportunity to kill the giant crocodile, and the ten-meter giant crocodile made Yang Qian deeply jealous, so he dispelled the idea of killing the giant crocodile, but Yang Qian was not in a hurry to leave, but guarded the edge of the waterhole, there are many mutant beasts in this forest, there are always mutant beasts to go to this waterhole to get water to drink, if the giant crocodile attacks, Yang Qian will wait for the opportunity to move the crocodile mouth to grab food
