There was a deathly silence all around, and even the breeze seemed to be afraid to see the raging battle here.

After the alien monster was driven into the depths of the forest, it didn't make a sound, as if it had disappeared out of thin air.

Zhen Xin calmly looked around, and at the same time quietly turned on the monitoring function of the special operations watch, measuring the surrounding air fluctuations and temperature changes at all times, so as to detect the traces of alien monsters.

Although this special operations watch does not have the powerful battlefield reconnaissance function of Xiao Ai, it can always monitor extremely subtle air fluctuations and temperature changes within 30 meters of the surrounding area by relying on some sensitive sensors it has, and in special circumstances, it can also play a certain role in reconnaissance.

"Thirty-five degrees in front of the left, there is an abnormal temperature increase at a distance of twenty-five meters, please be careful!" The special operations watch made a faint sound, just enough for Zhen Xin to hear clearly.

Zhen Xin didn't hesitate at all, he raised his gun and fired, and a laser beam shot into the depths of the forest in an instant, and then there was an angry scream from the alien monster, which was caught in the rumbling explosion, which was particularly clear.

After the explosion, the forest became quiet again.

"Ten degrees behind the left, thirty meters away, the air is unusually fluctuating, please be careful!" A few minutes later, the special operations watch sent another reminder, and Zhen Xin then attacked, which immediately caused an even more angry scream from the alien monster.

After repeating this three or four times, the alien monster finally lost patience, no longer hid its body, and launched a powerful attack directly 30 meters behind Zhen Xin, sixteen violent flames, connected into a leather whip, as if being shaken by an invisible big hand, breaking through the barriers of layers of strange trees, and rolling directly towards Zhen Xin.

Zhen Xin raised the gun and fired, one after another laser beams accurately hit the flames in the fire whip, and the fire whip was scattered in the blink of an eye, but the left hand quietly took out the electromagnetic pistol, and took advantage of the moment when it was attracted by the laser, and fired three miniature guided cloud explosion bombs in a row, shooting towards it from three directions.

"Boom, boom, boom......" It wasn't until the missile approached that the alien monster found the abnormality, and was naturally blown up by three missiles, and the light cluster that protected it was like a giant balloon rubbed by more than a dozen palms under the impact of violent shock waves and air pressure, and in the bursts of tooth-souring "squeak" sounds, it changed into various strange shapes.

"Twitter......" The alien monster let out a short, panicked scream, and the eight pairs of tentacles couldn't stop shooting out a dazzling red light, injecting it into the light cluster that protected him, as if it was sending energy to the light cluster to sustain it. Unfortunately, under the shock wave that oscillated back and forth, the red light of the light cluster became more and more dim, like a candle lit in the wind, and it was in danger of being extinguished at any time.

In the face of such a good opportunity, Zhen Xin naturally would not miss it, he immediately launched a fierce attack towards the light cluster that was about to collapse, and the light cluster that was about to collapse finally let out an unwilling roar under the attack of one laser beam after another, and suddenly exploded into a spark in the sky.

By chance, the alien monster happened to be thrown by the violent explosion, Zhen Xin's eyes were quick, and he raised his gun to shoot a laser towards the center of the monster's disc-like body, and the monster immediately let out a terrible scream, and its body was blown up into a rain of turquoise blood by the huge energy carried by the laser.

Zhen Xin was taken aback, worried that there was something strange in those blue bloods, so he hurriedly avoided the blood rain that was sprinkled, but in the corner of his eye, he saw that the blood rain was mixed with a fist-sized round transparent crystal, which happened to fall in the grass layer not far from him.

He looked over in surprise, and saw a ball with an extremely regular shape, transparent like crystal, lying quietly in the middle of the grass, but from time to time there flashed a flame-like red light in the ball, rising and disappearing, light and dark, looking extremely gorgeous.

Zhen Xin was about to take a closer look when there were suddenly countless terrible roars in the distance, exactly the same as the screams of the dead alien monster, and the cries were getting closer and closer, as if they were rushing towards this place. He couldn't help but be taken aback, one monster is enough for him, and if he comes to the next batch at this time, will he still be alive?

Zhen Xin hurriedly cut down a few branches, carefully held the ball, and retreated towards the lake rapidly, while carefully destroying the traces left by his actions.

The lake was not far from here, and after ten minutes, he was back at the lake again. Without the slightest hesitation, he jumped into the lake again, carefully washed the ball with the water, and after making sure that there was no harm, he grabbed the ball and swam to the middle of a patch of aquatic weeds, using the aquatic weeds to cover his tracks.

The round ball feels warm and cool in your hand, as if you are really holding a crystal ball, and it feels very comfortable in your hand. But in his clear sense, the cognitive energy pile in the center of his eyebrows suddenly accelerated its speed, and a strand of light with the thickness of a hair flowed out smartly, passing through an unknown channel on his arm, and connecting to the ball in his hand.

The moment the streamer touched the ball, his brain suddenly went into a trance, and then a clear feeling came to his heart, just like his nose smelled the fragrance and his fingers touched the jade, his brain naturally gave the fragrance and smooth and warm feedback.

He felt the powerful energy in the orb, a violent and orderly hot energy, so frightened that he almost threw it away.

Calming down, he carefully felt the energy in the ball, and a thought suddenly came to his mind. This orb is supposed to be the energy crystal nucleus left by the fire spirit people, called the fire spirit crystal nucleus, which is filled with a huge amount of geothermal energy, which can easily melt large areas of rock into magma.

This feeling is like smelling the scent of roses, which is sure to be the fragrance of roses, because he has smelled it before, and this feeling has become a kind of common knowledge for him. Now that his perceptual energy touched the ball, he made a judgment at once, as if he also had common sense in this area.

What's going on?

He was extremely surprised in his heart, and suddenly remembered what the old man of dark energy had said, the perception energy is the power that the earthlings specially use to sense the external things, just like the sixth sense.

His energy stack was built under the guidance of the Sancai Dao Sword left by the old man with dark energy, and the cognitive energy in it should also inherit all the experience and insight of the old man with dark energy, and then this experience and insight was triggered by familiar things and became his own experience and insight. Presumably, this was the reason why he was able to tell its origin when he first came into contact with the energy crystal nucleus of the Fire Spirit Star.

After figuring out the key, Zhen Xin's mind settled down, and his mind turned to another sentence of the old man with dark energy, and began to figure out how to use the sensory energy.

Since the perceptual energy can sense the energy crystal nucleus, it should also be able to sense other things, it can sense things close in his hand, and he can sense things farther away, but how can he control these energies?

He carefully recalled the process of sensing the energy crystal nucleus just now, and found out sadly that the perception energy ran out completely automatically and spontaneously, and had intimate contact with the fire spirit crystal nucleus, which had nothing to do with him, the master, but why did this happen?

He was puzzled, and carefully recalled what the old man had said, and suddenly a sentence jumped into his mind, the old man once said that these three energies are the most magical dark energies, with strong affinity, and they can be found and manipulated through these three energies.

Doing what he thinks of is always his strength. He hurriedly changed the crystal nucleus to his left hand, and the wisp of perceptual energy immediately retracted into the energy pile, and at the same time, a perceptual energy flowed out from his left arm, touching the crystal nucleus.

He was extremely excited in his heart, and the crystal nucleus kept switching between his hands, guiding the flow of perceptual energy to flow back and forth, and slowly he actually found a little sense of control.
