Yu Xiao's expression changed drastically, he felt his scalp numb, and there was a look of fear in his eyes. If he was surrounded by this group of blood fairy insects, his end would definitely be very miserable.

He had seen before how powerful this mutated blood fairy insect was. Not only were they powerful, had sharp teeth, and were more aggressive, they were also rough-skinned and thick-bodied and not afraid of flames. It was not easy to kill them.

What's even more terrible is that once these blood fairy insects set their sights on a target, they will not give up easily. He never expected that there would be so many mutated blood fairy insects here.

"Damn it!"

Yu Xiao cursed in his heart that he was unlucky. He didn't have time to think too much and directly used the black cauldron. The latter's size increased several times and shed rays of rays of light to block the approach of the blood fairy insects.

However, this magical weapon can still have a good killing effect when faced with ordinary blood fairy insects, but it has almost no effect when faced with a group of crazy mutant blood fairy insects.

Those rays of sunlight shining on the blood fairy insects only caused them to scream a few times and emit a few wisps of white smoke, but could not directly kill them.

Moreover, after eating painful blood fairy insects, they will become even more ferocious, with their eyes filled with scarlet red, and a pair of jaws colliding with each other like a meat grinder at full power.

Seeing that the black cauldron could not stop the Blood Fairy Insect, Yu Xiao decisively drew out the sword diagram again. Hundreds of small black and white swords erupted in the air with dazzling sword light, slashing them down one after another at extremely fast speeds.

When the sword light fell, the Blood Fairy Insect was hit hard, with many scars on its body, and its movements became much slower.

However, after a while, those blood fairy bugs started to bite the black and white sword like crazy. As soon as they met each other, the black and white sword fell down in large pieces.

Seeing that the situation was not good, Yu Xiao didn't dare to stay. He immediately put all the small swords into the sword diagram, turned around and ran away.

However, the blood fairy did not intend to let him go. Its speed soared, its wings flapped loudly, and it was soon approaching. Yu Xiao could even feel the sharp wind passing over his head, and his mood sank to the bottom for a moment.

.

At this time, an urgent voice came from the side: "Fellow Taoist, it's safe here! Come here quickly!"

After hearing the sound and looking for it, Yu Xiao saw a strange ancient tree not far away, with three people standing underneath. They were surrounded by spiritual energy, as if there was some kind of formation barrier. At this moment, someone was waving to him.

Seeing that the blood fairy insects were about to catch up behind him, he had no time to hesitate and immediately turned around and galloped towards the strange ancient tree.

It was too late, but it was faster than that. As soon as Yu Xiao's front feet arrived, the blood fairy insects behind him had already fallen.

Fortunately, the three people were prepared in advance. One of them used a magic trick to open the barrier in front of him and let Yu Xiao in. The other two used magic weapons to delay the blood fairy insects.

After Yu Xiao entered the barrier, the man immediately lowered the restriction and closed the barrier. The Blood Fairy Insect failed to succeed. It was very angry, let out a squeaking roar, and attacked the barrier crazily.

But the barrier in front of him was very strong, and no matter how the blood fairy attacked, it failed to have any substantial effect. After a lot of efforts to no avail, the blood fairy flew away unwillingly.

At this time, the three of them breathed a sigh of relief, and Yu Xiao felt a lot more relieved. It seemed that this place was indeed safe.

He then looked at the people present, his eyes fell on one of them, and he was a little surprised: "It's you!"

Among the three people, there was a handsome young man in white, who was the young master of the Phantom Sect, Mu Yunqian.

The two people next to Mu Yunqian were both disciples of the Phantom Spirit Sect. The three of them seemed to have been here for a while, and their faces were full of sadness.

"It turns out that I am a fellow Taoist from the Fuguang Sect. I am disrespectful and disrespectful." Mu Yunqian replied politely. He did not look down on Yu Xiao because his cultivation level was lower than his own.

A few of those who can enter large sects and become disciples are ordinary people. If the gap in cultivation is not particularly large, it actually has little reference significance, unless they are disciples with perfect spiritual roots like Song Xi.

"Master Mu, you are so polite. I'm Yu Xiao. I would like to thank the three fellow Taoists who came to the rescue just now." Yu Xiao said in return, cupping his hands.

Mu Yunqian waved his hand carelessly and smiled bitterly: "It's just a little effort. Besides, Fellow Daoist Yu is only temporarily safe. The group of blood fairy insects did not completely fly away. They are just waiting for their prey to appear.

As long as we leave this barrier, they will notice it immediately, and then surround us and attack us, and we...are all trapped here."

"I see!"

Yu Xiao had previously found it strange why the three of them didn't go collecting spiritual herbs, but instead sat leisurely.

Now he understood that it was not that the three of them did not want to leave, but that they were also targeted by the blood fairy insects and could only rely on this method to temporarily save their lives.

Now they can be considered to be in the same boat.

"By the way, Fellow Daoist Yu, are you the only one here?" Mu Yunqian asked aloud.

"Yes, I'm the only one." Yu Xiao nodded. He also knew that the other party wanted to find more helpers to deal with those blood fairy insects, but this place is really special and not many people can enter this place.

If he hadn't followed the blood fairy all the way here, he wouldn't have discovered the stone formation, let alone tried to enter it.

"It seems that we can only go out when the forbidden area of ​​the building is closed." Mu Yunqian shook his head and sat down calmly. Since he couldn't go out, he might as well wait.

Yu Xiao was not as dejected as the three of them. His attention at the moment was attracted by the strange ancient tree behind him.

This tree is tall and straight, like a pillar. The trunk is thicker than a vat. There are lush bright red leaves on the top. The crown is shaped like an outstretched arm. When you get closer, you can smell a strong scent of blood from the bark, which is very attractive.

.

"This tree...could it be the Yuandan Tree?" Yu Xiao's pupils narrowed slightly, and he instantly understood why those blood fairy insects had mutated so much.

Yuan Dan Tree, as its name suggests, it can breed a spiritual fluid called 'Blood Yuan Dan'.

Xueyuandan is actually the gum of the Yuandan tree. It is bred from the inside of the Yuandan tree. After a long period of penetration, a group of spiritual liquid fruits similar to wolfberries are formed on the surface of the bark. Because of its appearance, it looks like a pill.

Medicine is the same as blood, so it is named Xueyuandan.

Blood Yuan Dan is of great benefit to both spiritual beasts and humans. It can stimulate the potential of the human body. It is not a problem for mortals to live to be more than a hundred years old after taking it to strengthen their bodies. Monks can even use them to

Strengthen the body.

If a spirit beast eats the Blood Essence Pill, it will evolve and mutate to varying degrees, and can even complete a transformation process that takes decades, or even hundreds of years, in a short period of time.

Those blood fairy insects must have undergone such a big change after eating the Blood Essence Pill.

The more you eat this kind of thing, the more obvious the effect will be. It seems that the newly appeared blood fairy insect king ate very little. After leaving the stone formation, he encountered other blood fairy insects and started cannibalism, heading in the direction of the insect king.

Metamorphosis.

The previous blood fairy insects, because they ate too much, far exceeded the mutation range of normal blood fairy insects, and they could not kill each other, so they could not give birth to an insect king.

Therefore, they can only grow bigger and stronger, and without an insect king to lead them, they will turn into a group of crazy insects that hunt entirely by instinct.
