"The blood from the plague and cholera patients was fused into the bodies of healthy men, resulting in fever, headaches, vomiting blood, and more than two months of death. The pen and fun pavilion www.biquge.info are not valid for martial artists in the Yuan period"

"Joining the latest malaria in the northern part of the Western Jin Dynasty, the object of the recuperation period to the condensation period, resulting in: bleeding from the mouth and nose, trembling all over, unable to take care of himself. It is not effective against the martial artists of the Condensation Period"

"Based on the joint practice of the Heavenly Absolute Sect Poison Grandmaster and the Elder, and combined with several kinds of refining poisons, the final emergency is obtained, which is a growable poison, which can only infect ordinary people at first, and then spread to the martial artists of the Yang Yuan period, after a few months, it can lead to the poisoning of the martial artists of the condensation period, and the time of death is shortened to one month."

This is the development process of this plague that Xu Fei saw, there were some experiments during the period, and there were also women's diaries that told the beginning and end of this incident.

This woman's name is Yu Bilu, her father is an inner disciple of Beiyin Mountain, she was born to his father's maidservant, there is no main room in this world, for the children, they are all equally compassionate, the family relationship is very good, and even she has practiced the inner door condensation exercise under the guidance of her father early.

It's a pity that the good times didn't last long, in a mission to the sect, the same door killed each other, Yu Bilu's father died, at that time she was only less than one percent of her strength, in order to avoid the enemy's weeds and roots, she and her mother hid in this desperate door.

In the process of escaping, her mother also died, her spirit was a little abnormal, she was only thirteen or fourteen years old at the time she was accepted as a disciple by an elder of the Heavenly Absolute Gate, she grew up in Beiyin Mountain, and was most familiar with poisons and infectious diseases, because this is the best skill in Beiyin Mountain.

Yu Bilu, who had experienced the destruction of her family, was mentally disturbed, and was guided by her master to take revenge, and her master also asked her to work the disease and plague, after all, the upper strength of the Heavenly Absolute Gate and the Seven Evil Sects was about the same, if they had such a virus, destroying the foundation of the Seven Evil Sects would be tantamount to a big killer.

When she broke through to the spirit core stage, she began to deploy this plague, which lasted more than ten years, and only then did it begin to take shape, and this city was also assigned to her by the Heavenly Absolute Sect for experimentation, and all the rich and powerful such as high-ranking officials, wealthy businessmen, etc., withdrew from this city early, leaving these civilians and the disciples of the Seven Evil Sects who were captured in the past to cultivate the plague.

"Smack"

Xu Fei closed the notebook angrily, the deeds inside made him shudder, and it was hard to imagine how many people would die if the plague really spread.

"Fortunately, at the moment, they are committed to spreading the martial artists of the Spirit Core Stage, in fact, the current virus has a 100% lethality rate for ordinary people, but after death, the transmission rate will slow down suddenly, and they only need to be isolated to block the transmission."

The records do not say how to treat this plague, and it seems that it is just blindly pursuing the transmissibility of the plague, so when Bilu experimented on a large scale, the Heavenly Absolute Gate transferred most of the population in the city.

Xu Fei was helpless, he was not a doctor, and he did not have the conditions to heal the suffering.

The only thing he can do is to destroy the current root cause, remove the high-level virus in this underground palace that can spread the martial artists of the Condensation Period, if this virus spreads, I am afraid that ordinary people will be infected for a day or two to die.

To deal with this infectious virus, Xu Fei can only think of two ways, one is to bury it deeply, and the other is to burn it on the spot.

After the virus leaves the human body, the survival time is very short, and it will die out quickly when buried deep underground, and if it is burned, the current conditions do not allow it, he is only one person, and he is in a foreign country, and the Heavenly Absolute Gate is even more-for-tat with the Seven Evil Sect where he is located.

It was obviously impossible to ask for help, but fortunately, the place where the sick were held was an underground palace, and only the destruction of the load-bearing walls and supporting stone pillars would cause the ground to subside, making it an excellent burial place.

Xu Fei inspected the underground palace, there are twelve stone pillars, and there are five huge walls on the wall, which is daunting, in addition to two vents and three exits, it seems that this underground palace is not just entered from the town guard's mansion.

For ordinary late-stage spirit core martial artists, it is easy to destroy a few stone pillars and walls, but the dungeon is really huge, and it is impossible to say that this ground will collapse when you are all demolished, right?

However, Xu Fei has his own way, his body is standing at an exit, with five black sword lights condensed in his hands, and he shot with all his strength, the sword light attached to the heaven and earth vitality increased several times, and a sword swept over, and the stone pillar was divided into two, he was cut down diagonally, and the stone pillar was changing and slipping.

The rest of the sword light was also under his control, destroying the rest of the stone pillars respectively, but Xu Fei didn't care about the wall, because the four walls were hollowed out of the ground, and only the center had an artificially built wall, and when the stone pillars were broken, the wall would naturally collapse.

"Boom~Boom~"

As the stone pillar was cut off and gravity pressed down, the ground collapsed instantly, and some of the surviving infected people in the underground palace were all buried alive.

It's not that they don't want to save, but they are all already like a terminal, and the reason why they are still alive is because the aura in their bodies hangs on their lives, so it is better to let them be born as soon as possible.

"Huh"

Xu Fei rose into the sky, and only then did he see clearly how large the scope of this underground palace was, and the edge even spread to the street next to the inn where Xu Fei lived.

The ground seemed to have been punched hard and sunken in, in order to prevent some people from digging the ruins of the town guard's mansion for money and their lives, causing the virus to spread.

Xu Fei stood in mid-air, his aura gushing all over his body.

The sword light blew with all its might, causing the heaven and earth vitality to fluctuate violently, and a sword light that was several meters long and two people wide was like a hoe, crushing the ground back and forth, this move only had a wide range, but in fact, the power was not as good as the three-foot-long condensed sword light.

The spiritual core in the body was improved, and his own perception was also supplemented by the origin of the world, and the evil power in the sword light was no longer the dark purple at the beginning, but a pitch black, like white paper stained with ink.

It was night, and some of the surviving people could only see a black pillar of light moving back and forth in the ground.

"Boom, boom"

A huge roar kept coming.

The sword light is a conglomeration of spiritual energy, absorbing the vitality of heaven and earth and bombarding the ground wildly, bombarding some remaining materials, roofs, tiles and other things into powder.

When a semi-circular pit had formed at this pit, and when he couldn't see the previous outline, Xu Fei collected the sword light and dodged back to the inn.

He is not worried about the excessive consumption of spiritual energy at this time, in case someone from the Heavenly Sect arrives and is made dumplings.

At this time, Long'an City was the most threatening, the highest cultivation had already been killed by himself, and the powerful people had already evacuated this dead city, so he was not worried at all.

The blood on his clothes had dried up, Xu Fei returned to the guest room, ripped off his clothes, and flipped the sword light back and forth, instantly turning the bloody clothes into pieces.

Picking up the oil lamp in the guest room and flicking it, the spark fell into the pile of broken steps, and the light of the fire instantly burned the clothes to ashes.

Fang Cai's subsidence and Xu Fei's bombardment of the sword light woke up the people in the city, although it was already midnight at this time, but the street was lively.

"Little Er, come, boil a bucket of water."

Xu Fei heard the conversation between Xiao Er and some people in the inn, and happened to be covered in sweat and blood, so he simply asked Xiao Er to boil a large pot of hot water and take a bath again.
