There is no moon tonight.

In the dark forest, the cold wind shuttled like a ghost.

The body of the silver bat monkey leader was pieced together. Because it was a warm-blooded animal, its body had not yet cooled down.

Needle Gold has now transformed into a complete Black Iron Bat Monkey.

The previous multiple changes consumed a lot of magic energy.

"According to my previous speculation, mutation is a simple life form, and the organs and parts are coordinated with each other and can bear each other's burdens. But when there are multiple changes, more of it is borne by the magic crystal in the heart.

Therefore, the consumption of magic energy will be more intense."

Zhenjin suppressed this further speculation and looked at the bat monkey corpse in front of him to make a new attempt.

Using his heart core, he once again sent out four blood lines from his palm.

The blood thread entangled itself and was immersed in it. After a few breaths, the blood thread resurfaced, transforming all the bat monkey's wings and sending all the essence into the core.

Zhen Jin checked it and felt happy.

"Now, I can become a complete silver bat monkey."

As soon as this thought fell, red light surged up and covered his whole body.

In the red light, his blurry figure quickly rose up, and the wings behind his back became wider. After the red light dissipated, standing there was the silver bat monkey needle gold.

"The strength has become stronger, but it is still not comparable to the monkey-tailed brown bear."

"sound……"

Zhenjin took a deep breath, and as he listened, he found that the Silver Bat Monkey's hearing was stronger than that of the Black Iron, and its range of sound reception was wider.

He tried sending out ultrasound waves.

It worked the first time.

A scene of canvas emerged in his mind, and all the surrounding things were displayed on the canvas. The canvas spread rapidly, extending to more than two thousand meters, and the edges began to blur.

"It seems that the ultrasonic detection limit range of the Silver Bat Monkey is twice that of the Black Iron Class."

Zhenjin closed her mouth, stopped making sounds, and then opened her mouth again.

The ultrasonic wave was activated again successfully.

Repeatedly, he found that every ultrasound could be emitted smoothly.

"It seems that my feeling is correct."

"The vocal cords of silver bat monkeys are more stable and more conducive to vocalization."

"I have been training every night these days. In the black iron bat monkey form, the ultrasonic waves are emitted with a success rate of eight or nine times out of ten. Now in the silver bat monkey form, I can achieve a 100% success rate."

"I also got results from this experiment. Because I absorbed enough low-level life forms of the same type, the bloodline information reserve is very complete. Absorbing high-level life forms does not even need to be complete, only a part is needed to obtain the bloodline.

Information, let me become a complete high-level life form."

Needle Gold quickly swept around.

He has other things to do.

The target of tonight's operation is not just a silver bat monkey.

He grabbed the body of the silver bat monkey with his feet, flapped his wings a few times, and quickly took off, leaving the murder scene.

Half an hour later, he arrived at a colony of flying squirrels.

This is the largest group of flying squirrels near the camp, with two silver-level flying squirrels.

Zhen Jin flew to the edge and saw the body of the silver bat monkey thrown into the treetops, and used ultrasonic waves to detect it.

Flying squirrels live in tree holes and underground, but under ultrasonic exploration, they are all revealed one by one.

Because flying squirrels have different life levels, their body shapes are also different. Black iron and bronze level flying squirrels also have some tiny external characteristics, which allows Zhenjin to determine their corresponding life levels.

The results of the investigation were no different from before, and the needle gold flew directly into the flying squirrel's territory.

Sensing the intruder, the flying squirrel group became restless, and soon a group of flying squirrels, led by a silver flying squirrel, pounced on Needle Gold.

Zhenjin watched the flying squirrels approach and stood proudly on the branch.

When he was close enough, he opened his mouth and unleashed a sound wave attack.

He had mastered the sound wave attack technique a long time ago.

In terms of acupuncture practice, the difficulty of emitting ultrasonic waves is even higher than that of sound wave attacks.

The human ear can hear sound waves, but not ultrasonic waves. The essence of a sound wave attack is not high-frequency sound, but a stronger breath that drives the vocal cords and produces a higher-volume sound.

Flying squirrels have very sensitive hearing.

This creature digs holes in the ground and uses its senses of hearing and taste to find food. It cannot see, but its hearing is very strong.

This advantage becomes their fatal weakness under the sound waves.

Back then, Zhenjin witnessed the Blue Dog Fox Wolf commanding a large number of black iron bat monkeys to make sound waves together and bring down a group of rats with silver flying squirrels.

Now, Needle Gold has taken the form of a silver bat monkey, and the sound wave attack it emits is more powerful than the combined force of a group of black iron bat monkeys.

Under the sound waves, the group of flying squirrels that had been so aggressive a moment ago suddenly collapsed, the flying squirrels screamed, and a large number of flying squirrels were directly killed by the sound waves.

Silver Flying Squirrel still wanted to resist, but Zhen Jin increased the volume again, and Silver Flying Squirrel fainted on the spot.

In an instant, Zhenjin solved the battle.

And more flying squirrels jumped out of the mouse hole, trying to escape.

In a sense, bat monkeys are the natural enemies of flying squirrels.

The leader of the escape was another silver flying squirrel.

Of course, Zhenjin would not let them go. Another sound wave killed most of the flying squirrels, and the other silver flying squirrel was also knocked unconscious.

The next step is to use the heart core to absorb the corpses of flying squirrels everywhere.

The magic energy reserve in the core has been rising steadily, reaching an all-time peak.

At present, Zhenjin has not discovered the limit of magic energy reserves.

Zhen Jin thought for a while, killed both silver flying squirrels, and used his core to absorb and transform one of them.

After achieving this step, Zhenjin's flying squirrel form has also been upgraded to the silver level!

"It's a pity that I can never discharge it."

In this regard, Zhenjin has tried many times, but has never been able to discover the discharge technique.

Acupuncture can learn from bat monkeys to emit ultrasonic waves, because the ultrasonic waves come from the vibration of the vocal cords. Acupuncture itself also uses human vocal cords to speak, and this life activity is very similar.

But discharge is not.

Human beings never discharge electricity.

According to the anatomy of Cangxu, flying squirrels discharge electricity through small muscle flakes throughout the body. These muscle flakes are similar to an eel that can discharge electricity in water.

Therefore, flying squirrel discharge is an internal muscle movement. But Jin is very unfamiliar with this area and is completely blank.

Learning to discharge electricity is more difficult than emitting ultrasonic waves.

Therefore, this time, Zhenjin did not kill all the unconscious bronze bat monkeys and black iron bat monkeys, he specially kept some.

"These are my pets."

You need to observe them and learn how they discharge.

After once again cleaning the battlefield and eliminating the carbon ash left by the transformation of the core core, Zhenjin set out again with the corpse of the silver bat monkey, the corpse of the silver flying squirrel, and the living flying squirrel that was still in a comatose state.

It took a lot of time, and Zhenjin was currently quite far away from the camp, so Zhenjin chose to return directly to the camp.

Silver bat monkey needle gold flying in the air.

Because he was holding the body on his hands and feet, he could not climb and jump at will among the trees.

The cold night wind could not blow away the hot blood in Zhenjin's body.

Once, Zhenjin led everyone to do their best to deal with a group of flying squirrels that only had the Black Iron leader. Now, he alone has destroyed an even larger group of flying squirrels.

After this night, his bat monkey and flying squirrel forms were upgraded to silver level.

The Gun Scorpion form is also Silver level.

Because he has eaten a lot of bear meat and snake meat these days, he can transform into many parts of the monkey-tailed brown bear and the crocodile-headed hammer-tailed anaconda. Especially the monkey-tailed brown bear is not far away from its complete form.

"As long as you give me enough time, I can become the king of the island!"

The cold wind whistled in Zhenjin's ears, and he flexibly flapped his bat wings behind his back to control every gust of wind.

The broad bat wings flew across the crowns of the trees. Countless beasts in the dark forest felt the life breath of needle gold, and all fled in a hurry, or huddled together, trembling with fear.

Zhenjin looked down at the forest at his feet. At this moment, he felt that he had trampled the forest and the earth under his feet!

Even though he couldn't see clearly, the ultrasonic detection was within a two-kilometer radius, and nothing could escape Acupuncture's detection.

"Now, I am the best hunter. No prey can escape my pursuit!"
