At night, the mountains and forests seem to be a little dead and silent, small creatures cannot survive, and the insects that used to be can't be heard anymore.

Ling Zhantian and his group took turns to stand guard, and they carried out tightly and methodically. However, Zhou Jie chose the northwest direction and sneaked into the mountains, he did not eat any energy for a day today, in order to maximize the growth of his strength.

Therefore, he planned to hunt and kill F-class zombie beasts at night to grow his strength.

With the Energizing Ring, he only needs four days to grow to the strength of the upper F-rank, so he wants to make the most of his body's growth, and now his combat power is 776 points.

It took more than an hour and ran all the way through more than a dozen mountains before Zhou Jie stopped.

The environment here is densely populated with trees, and it is a section where zombie beasts infest, Zhou Jie found an open place and took out the corpses of aliens and began to lure zombie beasts.

Zhou Jie vigilantly perceived the surroundings, and any wind and grass within a hundred meters could not escape his perception, so he squatted for more than ten minutes, and no zombie beasts came.

Zhou Jie was a little happy, which showed that the zombie beasts nearby had all hung up, and there would always be the most powerful one.

After about ten minutes, there was some noise in the jungle, and the piercing breath of the zombie beast.

Two spiritual red threads on Zhou Jie's forehead emerged, and he quietly approached the past, and at this moment, a monkey zombie beast rushed out from the hidden place in the woods.

With a speed of nearly 25 meters per second, it has been proven that it is an F-class zombie beast. Zhou Jie's speed in the middle of the F-level is only 25 meters per second, but the opponent's F-level early stage already has this speed.

The advantage of zombiemon in speed is very obvious.

Zhou Jie didn't use a laser knife at this time, and came out to fight at night, in addition to collecting the core of the F-class zombie beast, another thing was to exercise the use of the spiritual red line.

I saw that the two spiritual red threads began to entangle with Zhou Jie's movements, flying up and down, and stabbing at the zombie monkey, because the movement speed was too fast, but it was never able to pierce the zombie monkey's eyes.

The key points of the zombie beast are only the heart and head, Zhou Jie exercised patiently, and after ten minutes, the zombie beast seemed to be disgusted with this kind of battle with no place to use the strength, and actually gave up the energy flesh of the alien and rushed towards the jungle.

Only then did Zhou Jie take out the laser knife, quickly stepped forward, and slashed down the monkey with one sword.

"I still can't control it accurately." Zhou Jie shook his head and took out the core of the monkey.

Taking out mineral water from the space ring and flushing the gray core, Zhou Jie ate it, increasing his strength by 30 points, and the combat power value of the energy meter reached 806 points.

Glancing around, no more zombie beasts came, Zhou Jie put away the alien's corpse and headed deeper.

Generally, there are only two mountains in the zombie territory in the lower section of the F-level, and Zhou Jie advanced five mountains before stopping and starting to attract corpses again.

This time, after half an hour, no zombie beasts rushed over, and Zhou Jie also frowned, so he could only go deeper.

After several rushes, Zhou Jie heard a piercing roar of a tiger!

"Tiger?" Zhou Jie's face was solemn, tigers are such strong beasts, they generally have the strength of the middle section of the F level after their corpses are transformed, and the speed is 35 meters per second, plus the control of the spiritual red line is not enough, Zhou Jie is not an opponent.

After thinking about it, Zhou Jie still gave up the idea of killing the tiger and left in a different direction.

However, the tiger didn't plan to let Zhou Jie go, maybe he was really hungry, the tiger was looking for food everywhere, and just sensed the heat of humans on the nearby mountain, so he rushed over without thinking about it.

That super speed can even be seen at night.

Zhou Jie was forced to have no choice but to throw out an alien's corpse in order to destroy the disaster.

However, the tiger was very unappreciative, ignored the alien's corpse, and rushed towards Zhou Jie.

Zhou Jie was furious in his heart, although it was dangerous to fight with the tiger, but with the spiritual red line, he was not without a chance of winning.

At this time, Zhou Jie directly took the laser knife and reflexively killed the tiger.

Dodging a sharp pounce from the tiger, Zhou Jie's laser knife slashed wildly, but the tiger did not dodge or dodge, and desperately scratched Zhou Jie's chest with his claws.

Zhou Jie has a black and gold suit, and he also does not dodge or dodge, and directly slashes down.

"Poof!" A large wound was cut on the tiger's body, and blood flowed wildly.

But this did not have the slightest impact on the tiger zombies, even if the blood was drained, only the core of the heart position was fine, then it would not die.

Zhou Jie was knocked five meters away by a tiger's paw, and he saw that the tiger's long nails were scratched, which shows how much force the tiger used.

Seeing that he had broken his claws after failing to strike, the tiger was very angry, and pounced on Zhou Jie very quickly, and came to Zhou Jie's side in less than a second, directly attacking Zhou Jie's head.

Zhou Jie dodged, controlled the spiritual red line, and went straight to the tiger's eyes, roaring in his heart: "Medium!" "At such a close distance, if the spiritual red line hadn't been stabbed, the tiger's next blow wouldn't have been dodged at all.

This time, surprisingly accurately, the red thread pierced directly into the tiger's eye, stirring its brain to pieces.

However, the tiger's vitality is extremely tenacious, and it does not rely on the brain to command the battle, the damage to the brain only makes his perception ability disappear, but the speed is not affected in the slightest, and he directly stabs Zhou Jie in the position just now.

Fortunately, Zhou Jie subconsciously dodged and did not hit him.

The tiger lost its senses, its body shook, and its two thick front paws kept shaking in front of its eyes, trying to take away the thing that hit its eyes, but Zhou Jie didn't give it the slightest chance, and rushed forward and swung out the knife and cut off the tiger's head.

Seeing that the tiger fell to the ground, Zhou Jie took back the spiritual red line, and at this time he was covered with cold sweat, panting, and tired.

Take out the core of the tiger, this core is even more gray, the core of the zombie beast in the middle of the F-level can increase the strength by 20 points, and the energy enhancement ring is doubled, which is forty.

After eating this core, Zhou Jie's combat power value reached 846 points.

To be honest, it was risky to kill the zombie beasts in the middle stage, and the strength added to their cores was not much more than that of the early stage of the F rank, so Zhou Jie was not willing to fight with them until his strength was not strong.

However, at the moment of crisis just now, the control of the spiritual red line has improved a little, which can be regarded as an unexpected joy.

After looking at the energy meter, it was only nine o'clock in the evening, and Zhou Jie was here to go deep into the mountains and forests.

An hour later, he killed a wolf in the early stage of the F rank again, increased his strength by 30 points, and his combat power value reached 876 points, and then he quickly returned to the gathering place.

At two o'clock in the morning, Zhou Jie returned to the cave where everyone was, and at this time, it was Monroe Yan who was standing guard.

Seeing Monroe Yan looking around vigilantly, with a hint of pretended strength on his face, Zhou Jie walked over.

"Who?" Monroe saw a figure.

"It's me!" Zhou Jie answered and walked out of the darkness.

Seeing that it was Zhou Jie, Monroe Yan hurriedly ran forward and grabbed Zhou Jie's arm, smiling.
