Even if the lowest-level combat insect in the Demonic Spirit Realm came over, I'm afraid it would be able to kill a large number of people in seconds.

However, thousands or even tens of thousands of years ago, the Water Spirit Realm was also a middle-thousand world with a high level of civilization.

How could the level of a world drop? This was natural. Nothing in this world could remain unchanged. A world could even disappear, not to mention falling in level.

But since it can be dropped, it can naturally be upgraded. It's just that it's easy to drop levels, but it's extremely difficult to upgrade levels, and this process is difficult to reverse.

Xue Huan put the blue hat worm into a glass bottle and plugged it so that she wouldn't be afraid that it would run out.

No matter how powerful it is when it parasitizes the human body, it is still a small insect with fragile skin that can be killed with a single pinch.

Xue Huan still needs to keep it, and wants to try to use it to research a way to deal with the Zerg, so she won't kill it for the time being.

Without the parasitism and suppression of the blue hat worm, Si Yi's consciousness gradually regained control of his body. Seeing that he showed signs of waking up, Xue Huan quickly took him out of the space, put him on the bed, and left the bamboo building.

The person who is parasitized by the blue hat worm is actually still conscious and knows what his body has done, but he is unable to regain control. When he wakes up, he will most likely tell Valley Master Sun that he is parasitized.

Of course, even if he didn't say it, Xue Huan would have said it.

However, she still hoped that Si Yi could say it himself. After all, he was the person involved, and his words would be more convincing.

Xue Huan returned to Handan Courtyard and locked Mo Xuefei in the space again. She transformed herself into her appearance, drank a bottle of spiritual spring water, and replenished her spiritual power.

She had consumed a lot of spiritual energy today. The feeling of dry meridians was really uncomfortable, and the emptiness in her dantian also reduced her sense of security.

After refining the spiritual spring, Xue Huan came to the table and wrote a letter to Pei Ji, telling him everything that had happened in the past two days.

Just after she sent the letter, Sun Zhe sent someone to call her over.

Xue Huan knew that it was probably because of the demon insect parasitism.

After Sun Zhe heard him report that he was parasitized, he had to call everyone involved in the matter over to question them.

Xue Huan followed the servants to Sun Zhe's study. In addition to Sun Zhe and Si Yi, Sun Youxuan's siblings, Hua Lingbi were also in the study, and there was also a little boy about three years old sitting at the top.

Although the boy has a young face, he has a calm and reserved temperament that comes from having experienced the vicissitudes of life. His eyes are clear and bright after being washed away by all the worldly desires, like an old man in the shell of a child.

Judging from the way Sun Zhe stood respectfully below him, it was clear that the boy was of an unusual identity.

Sun Zhe introduced her: "Miss Mo, this is the ancestor of my Sun family."

Xue Huan couldn't help but wonder, the ancestor of the Sun family was actually a three-year-old child?

"Hello, senior." She stepped forward and saluted.

She was not from the Sun family, so it was inappropriate for her to call him ancestor. However, other titles were not appropriate either. So she simply decided to rank them by their cultivation level.

The boy in front of him looked like an ordinary person at first glance, but in fact, his cultivation was unfathomable, like the abyss of the sea.

Xue Huan didn't dare use her spiritual sense to investigate. She was no longer a novice cultivator, and she knew that rashly using her spiritual sense on another cultivator was tantamount to provocation. It would be fine if the other cultivator's cultivation level was lower than hers, but if they were higher and attacked her in return, she feared she would suffer.

Sun Wushang looked at her with a sharp gaze, as if he could see through her disguise at a glance.

Xue Huan's heart skipped a beat. She had already made some progress in illusion techniques, which could be said to be the most proficient among all her techniques. Even in front of someone whose cultivation was one realm higher than hers, she was confident that she would not be seen through. But in front of this person, she could not be sure.

Fortunately, he didn't say anything.

"Come." Sun Wushang waved towards Hua Lingbi.

A trace of panic flashed in Hua Lingbi's eyes. He restrained the urge to look at Si Yi and slowly walked in front of Sun Wushang, still holding on to hope.

Don't scare yourself. The old ancestor of the Sun family must have called them here because of the Lianhu incident, not because he saw through her.

However, the next moment, her hope was shattered.

Sun Wushang didn't say anything, but just raised his hand and gently brushed across her eyebrows. Hua Lingbi was shocked. To be precise, it was the blue hat worm that was parasitic in her body that was shocked. It felt an uncontrollable force dragging it out.

This guy found it!

The blue hat worm wanted to run deeper into Hua Lingbi's sea of ​​consciousness, but to no avail, and was eventually pulled out.

Sun Wushang pinched it between his fingertips. The six legs of the blue hat worm twisted and entwined like snakes, trying to get into his body, but failed. It wanted to escape again and tried to break free from his grip, but still failed. He was so angry that he cursed wildly.

Unfortunately, no one present could understand what it was saying. The blue hat beetle does not have the human body structure and naturally cannot make sounds like humans. Their native language sounds like insects to human ears.

After seeing with his own eyes that Sun Wushang took a worm out of Hua Lingbi's body, Sun Zhe completely believed what Si Yi had said before about being parasitized.

Hua Lingbi clutched her chest and took a few steps back, looking at the bug with lingering fear. Sun Youxuan supported her shoulders, "Ling'er, are you okay?"

Hua Lingbi sighed and bowed deeply to Sun Wushang, "Thank you, Old Ancestor, for finding this bug for me. Otherwise, I don't know how many more mistakes I would have made."

She turned around and apologized to Sun Youxuan: "Brother Xuan, I'm sorry, I almost killed you. Fortunately, Miss Mo saved you, otherwise I would have made an irreparable mistake!"

Sun Youxuan was confused, "Ling'er, when did you almost kill me?"

Si Yi said in a deep voice, "Let me explain this matter. Liuqu, the blue-hatted worm that parasitized me, raised a nest of red threadworms in a secret cave in the back mountain. He deliberately hunted wild animals to feed them, hoping to cultivate red thread flowers."

Sun Youwei interrupted: "What is red thread flower?"

Si Yi: "Have you ever seen mushrooms growing on dead trees? Those red thread flowers are the flowers that bloom on the bodies of wild animals after the red threadworms have sucked the blood and flesh clean."

As soon as these words were spoken, everyone present felt a chill in their spines.

"Liu Qu said that eating this flower can rejuvenate a person. At first, he used wild animals to feed the red thread worms, but he never managed to cultivate the red thread flower. Later, he secretly hired people to kidnap beggars and even hunters in the mountains, and used living people to cultivate the red thread flower."

Sun Zhe angrily slammed the armrest of the chair: "Beast!"

Si Yi clenched his fists and continued, "I don't know how many people died, but Liu Qu finally cultivated a red thread flower. Sixth Junior Brother accidentally discovered the cave and picked the red thread flower in advance, causing it to wither."
