With the shining of the giant gate star, another nebula was born, and now Gu Yu is 4 nebulae are running, and the evolution of motor neurons has reached 20%.

He believed that with the power of the 4 main stars, coupled with advanced equipment, there would be no problem in dealing with the ordinary Venus Apocalypse!

After finishing his cultivation, he broke through the thin layer of ice covering the entrance of the cave and quickly chased after Zhuang Yinyue and his party.

Although it took a lot of time, he now that the second star of the motor neuron had been lit up, the speed was much faster than before, and Zhuang Yinyue and they deliberately slowed down and waited while walking, so they quickly caught up.

Several people continued to move forward under the leadership of the man, and after walking for most of the day, Gu Yu suddenly discovered a new problem.

It's not early, but it's still bright, and it looks like there's still a lot of time left for night.

"The days are getting longer and longer...... Zhuang Yinyue also noticed something unusual: "Are we close to the Arctic Circle?" ”

"Yes!" The man nodded: "This season, the core area of the Arctic is the polar day, and the place we are going to is at the edge of the Arctic Circle, on the shore of the Arctic Ocean, and the nights there are very short these days." ”

Zhuang Yinyue nodded, and a name inadvertently popped up: "Zheng Qi......"

"That's right, Dr. Zheng Qi!" The man turned his head and smiled: "The older generation of experts who study dark demons have made great contributions to the survival of human beings, and the unit of dark energy is established by his team after a long period of research. ”

"More than 70 years ago, he made a point." Zhuang Yinyue nodded, and said, "He thinks that since the dark demons like the night the most, then they are likely to come from the eternal night of the two poles - the polar night!" ”

"For example, when the Arctic Polar Night comes, the night starts from the pole and lasts from the pole, and it is from here that the demon's door is opened, and the dark demon is released and ravages everywhere. And when the range of the polar night gradually expands to the entire Arctic Circle, the demon's gate is also opened to the maximum, more and more powerful dark demons appear, and the activities of the dark demons reach their peak! ”

"After that, the range of the polar night gradually decreased, and it began to decline towards the North Pole, and the demon's gate gradually closed, and the activity of the dark demons weakened until it finally stopped, and the peaceful moon arrived......"

"The duration of the polar night is exactly half a year, and the activity cycle of the dark demon also happens to be half a year, this is definitely not a coincidence!"

"yes!" The man continued: "When the Arctic polar night ends, the long polar day begins, but this means the beginning of the Antarctic polar night, another cycle, another reincarnation, the same way, the same catastrophe, but from the North Pole to the South Pole, the position is reversed, maybe this is the number of days......"

"A polar night lasts for half a year, and the two poles add up for exactly one year, and the time coincides completely!" Zhuang Yinyue sighed faintly: "This argument of Dr. Zheng Qi has been approved by many people!" It's a pity ......"

"It's a pity that ......" the man shook his head with a wry smile: "There has never been conclusive evidence to prove this!" Because, the polar night is a forbidden area, no one can enter it alive, all signals cannot penetrate, not even satellites can observe...... No one knows what happened in the polar night......"

"Forget it, none of that matters." Zhuang Yinyue smiled: "Even if the dark demon does come from the polar night, what then?" There is no way for humans to stop it for the time being, and how many strong people have entered the polar night, and they have not come back in the end......"

The topic became a little heavier, and everyone stopped talking.

The nights get shorter, but they still come.

However, due to its proximity to the Polar Day region, the dark demons that appear here are not strong, and it is very easy to deal with.

Gu Yu's sensory neurons have evolved to 20%, he doesn't plan to let the sensory neurons and intermediate neurons drag him back, and when he was backwatering before, Zhuang Yinyue had also seen him cast a sour mist, so there was no need to continue to hide.

Therefore, this time he changed the way of fighting, directly controlling the Dark Demon in front, and then attacking with acid mist, although he did not show the Crazy Fang Battle Banner, but the helmet's rune combat skill "King's Landing" could directly control a level 2 Dark Demon, so the efficiency was not greatly affected.

The only effect was that Zhuang Yinyue couldn't help but look at him a few more times.

After all, people's habits are difficult to change, Zhuang Yinyue always felt that this way of fighting was somewhat familiar, especially with the same left-handed weapon, she naturally thought of Gu Yu.

It's just that she didn't know that Gu Yu had evolved motor neurons very high, in her impression, Gu Yu was a dual cultivator of sensory neurons and intermediate neurons, and the guy in front of her was obviously cultivating motor neurons and intermediate neurons, which made her constantly deny the other party's true identity.

Just as she was thinking wildly, there was a sudden roar in the air!

When I looked up, I saw two fighters approaching at a rapid pace!

"Level 3 Dark Demon!" She suddenly remembered that this was the two-headed level 3 dark demon she had seen before, and the dark energy in her body exceeded 500 units, which was not easy to deal with.

At this moment, the man's eyes lit up, and he already had a golden longbow in his hand.

B-Rank Silencer Weapon Day by Day!

The psychic power exploded, transmitted to the Sun-Chasing Bow through both hands, and condensed into an energy arrow, the hand shook, the bow received the arrow, and the energy arrow flashed, hitting directly on one of the fighters.

"Bang!"

With a bang, the fragments flew in all directions, and in just a moment, they had already injured the level 3 dark demon.

This man is worthy of the Venus Apocalypse, his strength is indeed strong, and a spiritual energy arrow flew thousands of meters, accurately hitting the high-speed flying fighter.

The two Level 3 Dark Demons immediately regarded the man as the most threatening target, and the dark energy converged into the cannon, each inspiring a series of pitch-black energy balls.

Gu Yu was not idle, with a move of his hand, an acid mist spread, forming an interception net, and the energy ball flew into the acid mist, quickly corroded away, and it was impossible to get close to the man at all.

Immediately, the man's body leaned back, the bow pulled the full moon, and the three psionic arrows condensed and flew towards the same target.

This is not over, after the three psionic arrows were struck, his entire body was almost lying on the ground, and an arm-thick thunderbolt condensed, resting on the bowstring and ready to attack.

"Thunderbolt!"

The man's body suddenly stretched out, and the thunder bolt was like a meteor catching the moon, and it sank into the shell of another fighter plane in an instant!

Both fighters suffered heavy blows at the same time, even the wings were broken, and they shook violently at the same time to fall.

And Gu Yu was waiting for this moment, seeing that the two fighters entered the attack range, he immediately raised his hand to summon two clouds of acid mist, enveloping the two fighters respectively.

The two level 3 dark demons were helplessly struggling to the death, but in the end, they were corroded by the acid mist, leaving only the broken shell of the plane to fall to the ground, swinging up the snow in the sky.

The man gasped heavily, the dark demons with more than 500 units of dark energy at both ends made him consume a lot, if there was no Gu Yu's help, it would be really a bit troublesome to deal with it alone.

And now, he can stay where he is and recover, and let Gu Yu and them solve the rest.
