The male lead went insane after the female supporting character gave birth to the main villain'

It doesn't matter if demonic energy enters Yu Chen Immortal Venerable's body, since it won't affect his cultivation.

However, the entry of malevolent energy will damage the meridians and dantian, severely affecting the cultivation of the Imperial Immortal Venerable.

Moreover, the demons and demonic cultivators sealed underground had their demonic energy greatly diminished and could only wait to die under the Heavenly Fiend Demon-Slaying Array.

However, due to the eccentric actions of the Immortal Venerable Qinghan, they received a large amount of demonic energy in return, recovering most of their strength. They then tried to join forces to break through the Heavenly Fiend Demon-Slaying Formation and escape.

Immortal Venerable Yu Chen immediately struck, knocking Immortal Venerable Qing Han away. He then took over the Heavenly Fiend Demon-Slaying Formation and fully activated it, suppressing the demons and demon cultivators once again.

When Qinghan Immortal saw that Yuchen Immortal was covered in demonic energy and had even helped the new Demon Emperor to injure him, he concluded that Yuchen Immortal was the former Demon Emperor.

Upon returning to Qishen Mountain, they invited powerful figures from various forces in the cultivation world to jointly activate the Demon-Slaying Array to kill him.

At this moment, because he had exhausted his remaining spiritual power to activate the Demon-Slaying Array, Yu Chen Immortal Venerable no longer had the spiritual power to resist the dual impact of evil energy and demonic energy. Although he still maintained his rationality, his heart had already fallen into demonic possession.

If the Demon-Slaying Formation is fully activated, it will also kill him as a demon.

He certainly couldn't just sit and wait to die, so he broke the seal and came out.

After Qinghan Immortal Venerable learned that he was Yuchen Immortal Venerable, instead of expressing gratitude for his self-sacrifice a thousand years ago and letting Yuchen Immortal Venerable go out to find rare and precious treasures to eliminate his inner demons and the demonic energy within his body, he joined forces with the powerful figures present to kill Yuchen Immortal Venerable.

Anyone would turn evil in this situation!

Thus, Immortal Venerable Yu Chen completely succumbed to demonic possession. Relying on his immense strength, he broke through the Demon-Slaying Array, shattered the protective barrier of Qishen Mountain, and departed gracefully.

Because he resented Qinghan Immortal Venerable for letting his evil energy enter his body, causing him to become a demon, he defeated the new Demon Emperor, occupied most of the demon territory, and kept causing trouble for Qinghan Immortal Venerable and Jiang Ling'er.

However, affected by the evil energy, his meridians were eroded, making it difficult for him to absorb either spiritual energy or demonic energy, which caused his strength to gradually weaken. In the end, he was killed by the increasingly powerful Qinghan Immortal Venerable and Jiang Ling'er.

After reading it, Su Yan asked in confusion, "System, why was this Yu Chen Immortal Venerable chosen by you? He has no health problems. If he wanted offspring, he could have easily found a Daoist partner to have one."

"Besides, isn't he cultivating the Path of Ruthlessness? Why would he want offspring? Don't you select targets based on whether they want offspring or not, but rather on whether they are major villains?"

It's going too far to force a child on someone who doesn't want one!

"Of course, we use the target's wishes as the selection criterion!"

The biggest villain in this world probably wants children deep down.

However, his memories were sealed away, and that person made him cultivate the Path of Ruthlessness, which is why the villain now appears to be without desires.

But without realizing it himself, he really wanted children.

"If you want to know the reason, you'll have to get close to the main villain and help him break the seal."

"Okay, as long as I know he wants children, I'm not really interested in the reasons."

She was just afraid that the child she gave birth to would not be expected or loved by the father.

After understanding the plot and mission objectives, Su Yan opened the adjuster and adjusted her body data to her desired settings.

There are no ugly women in the world of cultivation.

To counter the Mary Sue heroine's halo, one's appearance must be extremely beautiful.

Most of the fairy maidens in the cultivation world are ethereal and aloof, beautiful but commonplace after a while, and fail to leave a lasting impression.

The female lead, Jiang Ling'er, is different from most of the fairy girls.

She was pure and lovely, with a lively and adorable personality. Among the female disciples of Qishen Mountain, who were generally ethereal and aloof, she stood out. This was one of the reasons why Jiang Ling'er was able to attract so many fellow disciples of Qishen Mountain.

Su Yan remembered that when the original owner first arrived at Qishen Mountain, her four senior brothers would talk about what clothes looked good on her, what hairstyle looked good on her, how beautiful her smile was, and so on. They used all sorts of manipulation tactics on her, making her unknowingly become Jiang Ling'er's substitute.

The original owner was only slightly sweet and cute, but more beautiful.

Su Yan didn't want people to see her as a substitute for Jiang Ling'er, so she removed all that sweetness and slightly adjusted her features to make them more charming and spirited.

Especially the eyes, which are the windows to the soul, must be lively and expressive.

Finally, maximize her beauty and lively temperament to transform her into a lively beauty who embodies the essence of heaven and earth.

This is a world of cultivation, where people generally like things or people with spiritual energy or an ethereal aura.

Otherwise, so many young women wouldn't dress in an ethereal, fairy-like style.

There are many fairies with an ethereal quality, but fairies with a captivating and spiritual aura are quite rare.

After all, spiritual energy is something that is naturally bestowed, but immortal energy can be obtained through cultivation and can also be enhanced with the help of hairstyles, clothing, and other external objects.

Judging from the plot, there was no particularly spirited female supporting character.

This is unique, which will leave a special and unique impression on those people, and will help them get closer to her in the future.

The body shape can remain the same as the data from the previous world; no further adjustments are needed.

After adjusting the data, Su Yan remembered that she had one free lottery draw opportunity. "System, don't I have one free lottery draw opportunity? Please draw it for me."

With her unlucky constitution, she herself pulled out a "Thank you for your patronage" note.

"Host, feel free to draw the reward. There is no 'Thank you for your patronage' option in the rewards."

The experience of drawing a prize yourself is much better. After hearing what the system said, Su Yan couldn't resist and drew a prize herself.

"Congratulations, host, you have obtained a permanent bad luck charm."

"…Indeed, I shouldn't have taken any chances." Su Yan regretfully beat her chest and stamped her feet.

The system quickly reassured, "Host, this bad luck talisman is great too. When you enter the next world and see someone you don't like, you can stick the talisman on that person, and they'll be incredibly unlucky for the rest of their lives!"

"Even more unlucky than me?" Su Yan felt a little comforted.

If only I could be more unlucky than her...

Then wouldn't she be the unluckiest person?

???!

The system was actually quite confused. It had already discovered in the previous world that the host was indeed quite unlucky in small matters when not by the side of the main villain.

But when faced with major events, or when the host is about to encounter some danger, she always manages to avoid those major events and dangers by doing something unlucky.

It can't even tell whether the host has an unlucky constitution or a lucky constitution.

However, the host has no memories of the previous world, and she wouldn't know if we asked her, so let's not waste time going to the next world.

The system replied, "Yes, host, that person will definitely be more unlucky than you!"

"Does it also apply to female protagonists with a protagonist halo?"

"Yes, host, even the heroine with a lucky aura can't escape the bad luck charm produced by our system."
