Let's talk about its speed first. It is probably based on the mentality of "make up for what you lack". In order to make up for the shortcoming of its original inability to move fast, the leech generated a pair of wings for itself after metamorphosis. When it flaps its wings, it turns into a streak of light, and its speed is so fast that it is difficult to capture with the naked eye.

Shen Yizhi had to expand his spiritual sense to see its flight trajectory clearly.

The two tiny tentacles on its head act as its eyes to a large extent. They can collect information within a radius of at least several miles through vibrations, and then feed it back to it, allowing it to decide whether to attack.

Finally, the key point is the needle on its tail. After piercing the prey's body, it will also release toxins to paralyze the prey.

Compared to before, its blood-sucking speed has increased several times.

A chicken will turn into a dried chicken in less than a second after being stabbed by it.

A pig, less than three seconds...

However, after sucking so much blood, no one knew where it went, and its body remained so petite and delicate.

However, Shen Yizi observed carefully and found that after the leech butterfly had sucked enough blood, a circular pattern similar to an eye would appear on its wings. The pattern was bloody, like a real bloody eye, and looked quite scary.

It is estimated that this pattern is specially used to scare away the enemy.

The grass butterfly is so fast and can quickly suck all the blood from its prey's body, it seems to be invincible.

In fact, it is not.

Everything in this world requires balance; there is no such thing as an absolutely powerful creature.

The grass butterfly also has weaknesses, and they are particularly obvious.

Its body is extremely fragile and if caught by someone, a slight pinch could kill it.

Shen Yizi spread out her palms, and the grass butterfly stood in her palms, flapping its wings lightly, beautiful like a dream.

Before she left, she prepared some food for it, warned it not to suck blood casually, and then went out.

When Shen Yizi returned to the deck and saw the scene in front of him, he almost suffocated.

The grill was lying on the ground in a mess, and all kinds of sauces were scattered all over the floor, like spilled paint, staining the originally spotless floor into a black mess.

"Watch this!" Nian Nian threw a piece of meat towards Qing Bao.

When Qing Bao was about to dodge, he stepped on a puddle of soy sauce, slipped, and sat down.

He didn't cry, but just grabbed a chicken leg at hand and threw it back.

Luo Yaoyao not only did not stop them, but also watched with a smile and applauded them! Shen Yizhi: "..."

She had only been away for a while, and they had actually done this to her! She took a deep breath and repeatedly told herself not to get angry, not to get angry—

"you!"

The old man and three children turned to look at her as if frightened, their big, innocent eyes looking particularly innocent.

The world is so beautiful, how can I be so irritable?

Shen Yizhi forced a smile and tried to keep his voice calm: "Stand aside."

The old man and three children sensed the unrest in her calm tone and dared not make any more noise. They immediately stood aside obediently.

They stood in a row against the side of the ship, lowered their heads and conveyed information with their eyes.

Shen Yizi felt a headache when he looked at them once, and he was too lazy to look at them again, for fear of getting angry to death.

After cleaning up the mess on the deck, she glanced at the troublemakers and said, "Why are you still standing there? Clean up yourselves quickly. It makes me angry just looking at you."

"Come on, come on, master will take you to take a bath." Luo Yaoyao was like a hen, opening her arms and leading the three little ones in.

Shen Yizhi pressed his forehead.

When she thought that it would take at least five or six days to fly to Shanhaiguan, she felt like jumping off the boat.

Children are the cutest before they are three years old. Once they are over three years old, their evil index increases dramatically. What's more, there are three of them together, plus an old naughty boy who is eager to create chaos in the world. Life is unbearable!

Shen Yizhi was just about to turn around and go in when he suddenly felt a sharp pain in his heart.

She covered her chest and fell to the ground with a pale face.

Something happened to Gu Xueting!

Shanhaiguan.

A tall, snow-white wall stretches across the land, like a majestic and huge snow dragon, separating the inside and outside into two worlds.

Outside, it is a monotonous world composed of only three colors: white, gray, and black. It is desolate, vast, cold, and very dangerous.

The situation inside was not much better. Everywhere you looked there were weeds, snow, and gray-black trees, without a trace of green. Fortunately, there was a thick city wall that kept the danger out.

Humans were able to establish settlements here.

A few dozen miles away from Shanhaiguan, there is a small city called Suiyang City. Most of the people living in the city are the families of the soldiers guarding the border.

And there is a camp between Suiyang City and Shanhaiguan.

A giant black bird was hovering above the camp. It was Xiaoman who followed Gu Xueting. Following Gu Xueting's instructions, it acted as the aerial sentinel of Shanhaiguan, always paying attention to the situation outside the pass.

Suddenly, it let out a series of rapid but regular calls.

When they heard this sound, they knew that the monster was coming again! The assembly horn sounded throughout the camp, and the soldiers quickly grabbed their weapons and rushed to the city wall.

When they saw the densely packed monsters below, everyone's hearts trembled. This time, the beast tide was more massive than any previous one. Could they really stop it? However, the monsters did not give them time to react. They did not know any tactics. They just kept rushing over, constantly hitting the city gate and climbing up it, fearless of death.

"Kill!" Gu Xueting's voice was as cold as ice and iron, and it contained spiritual energy. It reached everyone's ears and awakened them from their shocked state.

Everyone stopped thinking and focused on the battle.

Arrows engraved with armor-piercing symbols were shot out like a rainstorm, and immediately a group of monsters fell down, but then more rushed up.

Above the city gate, soldiers threw heavy stones down from the battlements, smashing the monster that was ramming the gate into pieces.

The monsters that managed to climb up the city wall were also besieged and killed by soldiers armed with swords and guns.

However, there were so many monsters that it seemed impossible to kill them all. What made people feel even more depressed was that in addition to those on the ground, a large number of birds also flew in.

They are as fast as the wind and have sharp claws. They can grab a soldier and fly high into the sky. Once they loosen their claws, the soldier will be thrown to the ground and his brains will burst.

Gu Xueting said in a deep voice to the people around him: "I'll leave the ground to you, Brother Xiao."
