Anyway, Yun Zhiyi didn't bother with the cleanup.

Even without ventilation, she knew that Fu Yuanbo would definitely take care of it.

The Kongyang Sect is located two countries away from the Luoshui Palace.

Fortunately, the flying sword can travel thousands of miles in an instant, so it's just a matter of replenishing some spiritual energy.

It was already evening when she arrived at the Kongyang Sect.

Unlike Luoshui Palace, which is located atop a snow-capped mountain, Kongyang Sect is situated in a dense forest.

The surrounding forests and miasma served as a natural barrier for the Kongyang School.

Fortunately, this natural barrier exists; otherwise, the Blood Calamity would have spread long ago along with the incident at the Kongyang Sect.

The entire Kongyang Sect is now deserted, leaving only an empty sect.

The other sect elders who came to help almost went mad from the infection as most of them were infected.

So, in the end, the group decided to go all the way and simply killed all the other disciples of the Kongyang Sect who were showing signs of qi deviation.

The few remaining surviving disciples were all outside and thus escaped the calamity.

However, most of these disciples were outer disciples, and only a few were inner disciples, which was not enough to support the Kongyang Sect.

Moreover, when they returned, all the resources of the Kongyang Sect had been divided up by the various sects under the guise of labor fees.

What use is there in having only one sect that exudes an ominous aura?

So in the end, these people all went their separate ways.

In just a few months, the entire sect was like it had been abandoned for years.

Following the location left by the memory bead, Yun Zhiyi found the dense forest behind the mountain, next to an abandoned ditch.

This is the place where Zhao Liang, the half-demon who caused the downfall of the Kongyang Sect, obtained the demonic plant.

She extended her spiritual senses and carefully perceived the sensations.

Soon, they found a place where special energy resided.

The whole area here is covered with a small plant with white leaves and red flowers.

The plants all possess the familiar power of bloodlust.

It seems that after Zhao Liang took away that demonic plant, the seeds that fell from it sprouted into another patch.

However, the purity of the new Demon Plant Blood Calamity content is relatively low.

Of course, it still possesses terrifying destructive power and contagiousness.

She conjured a flame, scorching the small patch of demonic plants, and then tossed down a handful of seeds, which quickly sprouted and purified the area.

Then the spiritual energy surged downwards, and after descending several thousand meters, it finally touched a barrier, which it broke through with brute force.

The moment the barrier was broken, a ball of light shot out from the ground.

This time, she didn't grab it immediately. Instead, she used her spiritual power to envelop the ball of light, then flashed into the space, sat on the sofa, and absorbed the ball of light into her body.

Soon, a new and unfamiliar memory rushed into my mind.

This time, she was prepared, and she only felt dizzy for a short while; she didn't faint.

Then he began to carefully examine his memories.

The scene in the second memory bead begins with the half-demon imprisoned in the Luoshui Palace going mad and breaking out of the palace.

Although the half-demon was eventually killed by the Palace Master of Luoshui Palace, the corrupted disciple was also quickly dealt with.

However, she still managed to trace the person to her and, by following the clues, discovered the Kongyang Sect incident, which had been deliberately covered up and erased.

However, since she couldn't directly extract memories from the half-demon that time, she spent a lot of time finding the demonic plant that caused Zhao Liang to become a half-demon.

She took all the remaining newly grown magical plants and handed them over to the most authoritative Medicine King Valley for research.

Little did anyone expect that Medicine King Valley was the real culprit.

Whether it was five hundred years ago or one hundred years ago, the great catastrophe that almost wiped out the entire martial arts world had the shadow of Medicine King Valley.

The earliest history dates back 500 years. At that time, Yaowang Valley was not called Yaowang Valley, but Yi Valley, which took saving lives and healing the wounded as its mission.

He has an excellent reputation both in the martial arts world and in the secular world.

Everything changed because of that bloody incident five hundred years ago.

The man who almost destroyed the entire martial arts world in his attempt to break through to a higher level was named Tong Yu.

He wasn't a member of any sect; he was just a wandering swordsman.

On the surface, he appears to be upright, but in reality, he is a poison doctor who cultivates his skills with poison and enjoys various unorthodox research methods.

He once established a medicine sect, deceiving people who wanted medicine to cure their illnesses into conducting human experiments. He also secretly captured many people and cultivated countless medicine people in the underground palace.

Later, the people of Medical Valley discovered this and ordered all martial arts sects to eliminate him.

The medicine sect, which had only been popular for a short time, disappeared.

However, Tong Yu, the culprit, escaped death and later joined the Medical Valley under an assumed name, successfully infiltrating the organization by using his exceptional medical skills.

Originally, he only wanted to take revenge on Medical Valley and steal some resources to continue his research.

But perhaps dark things always attract each other.

While practicing medicine, he passed through a village and encountered a strange event.

People everywhere suddenly developed rabies.

It is said that someone was bitten by a rabid dog at first, and then the dog went mad and bit other people.

Then one after another.

When the news reached the county magistrate, he immediately ordered the village to be sealed off.

They even called a doctor to come and see.

But the doctors were all helpless in dealing with it.

The county magistrate then decided to continue sealing off the entire village, leaving the people inside to fend for themselves.

Using his identity as a doctor, Tong Yu successfully entered the village.

He discovered that these people didn't have rabies at all.

They all have a strange substance inside them, something that's like poison but not quite.

He suspected that someone had accidentally ingested some kind of infectious poison that could cause people to go berserk.

Then he followed the clues and gradually found the places the first dog to go mad had been.

In that small hill, he didn't find any poisonous plants, but he did find a small patch of unusual plants with white leaves and red flowers.

Tong Yu is a madman, especially when it comes to research; he's a complete madman.

When a normal person sees such a strange plant, and with the example of the entire village, they would either keep their distance or pick it to study it slowly.

But he just picked it off and put it in his mouth to taste it.

He then discovered that consuming these plants could rapidly enhance his internal energy.

But at the same time, it can also cause people to gradually lose control of their emotions.

He simply stayed in the valley, observing his gradually changing emotions and body each day.

Instead of seeking other methods to suppress it, they started cultivating this plant.

They then ate this plant every day.

Perhaps it was because he ate too much, but the purity of his blood essence increased, and he even gained some memories in his mind.

These memories are about how to create blood curses, transform them into internal energy, enhance strength, and quickly break through realms.

He was overjoyed and began to study it intensely.

The appearance of that patch of demonic plants was due to the very weak barrier between that area and the Blood Calamity, which indirectly affected the soil and caused the growth of a patch of demonic plants containing Blood Calamity.

It can also be considered the first generation of magic source.

However, the power of this magical plant is very low and not pure enough.

After taking it, one will be like Zhao Liang, needing to harm others and spread the disease through wounds and blood.

Based on that memory, Tong Yu did not create a blood pool like the Luoshui Palace.

Instead, he devised a conspiracy, gathering almost all the strongest martial artists in the world together in one place, and then using the Blood Calamity to make them kill each other.
