In terms of potential, it has increased by a full 3 points, which is also a huge increase!

The increase in potential value can make Su Changkong more demonic, and it will become easier and simpler to cultivate various martial arts, forming a virtuous circle!

The five fowl dramas and turtle breath skills broke through together, which made Su Changkong feel the relief he had not seen for a long time, but he did not slack off.

"Above the brave warriors, there must be stronger ones, who can be powerful near a small city, which is not a good thing!"

Su Changkong said secretly, forging the body realm, but the first realm of martial artists, there are people outside the people and mountains outside the mountains, don't be complacent.

Su Changkong practiced as usual every day, and he could feel that whether he was at the level of forging or sword technique, his progress had become easier and faster, and he only needed to practice hard to enter the 7th realm.

Winter goes to spring, the harsh winter has passed, and there has been a hint of warmth in spring as promised.

"Bell, bell!"

On the morning of this day, after Su Changkong finished practicing the Five Birds Opera, the bell of gathering and roll call rang in the Black Iron Villa.

As usual, everyone gathered in the square of Black Iron Villa, and Director Liu pointed his name.

"Qian Yue! Didn't Qian Yue come? ”

But soon, Director Liu's brows furrowed slightly, because he called his name several times in a row, but no one answered!

"Qian Yue...... He seems to be sick today and is resting in his dormitory. ”

Soon, a man spoke.

"Hmm...... Now that the weather is changing, everyone is paying attention to the temperature. ”

When Director Liu heard this, he didn't pursue it much, hundreds of people, it is normal for them to catch a cold and get sick.

Su Changkong didn't care about it, but this matter was not unusual!

Two days passed in the blink of an eye, and it was time for the morning assembly and roll call.

"Lu Yi has suffered some cold, let me help ask for a leave!"

"And Li Yi, he is not feeling well today, vomiting early in the morning, and he can't come to work today."

Someone spoke one after another, which made Director Liu's brows furrow.

"Is it the flu?" And Su Changkong's heart also moved, it was too unusual for so many people to get sick at the same time, Su Changkong thought of the flu with a certain contagion!

"Ahem, ahem...... I...... I seem to be sick too......"

At this moment, a man coughed violently, and his face turned pale.

Su Changkong remembered that this man's name was Sun Qian, and he was also the foundry master of Black Iron Villa.

"Ahem...... Ahem! ”

Sun Gan coughed violently, as if he was going to cough out his lungs, and the rest of the people nearby unconsciously retreated, with a look of worry on their faces, and Sun Gan also covered his mouth with his hands.

After coughing more than ten times, Sun Qian stopped coughing, but between his palms and fingers was blood-red.

"This ...... This ......" Sun Qian looked at the blood he coughed up, his face was pale, his body had always been very healthy, but he was so sick that he coughed up blood?

"Two people will send Sun Qian back to rest, and there will be Qian Yue and them...... Let them not even go out for the time being, and come into contact with other people! ”

Seeing this, Director Liu's face was unprecedentedly solemn and immediately ordered.

"Yes!"

Everyone agreed, and at the same time all looked heavy.

If it's the flu or something, it's fine, but if it's the plague...... That's trouble!

"Is it the plague? This winter has just passed! Su Changkong also frowned, but he knew that in ancient times, the most terrible thing was not only natural and man-made disasters, but also the plague, even worse than the previous two.

The level of medical care and sanitary conditions are limited, in ancient times, if you were infected with the plague, it was basically a matter of luck, you can carry it and live, and if you can't resist it, you can only wait for death!

Director Liu immediately reported the matter to Mo Tie, and Mo Tie also attached great importance to it, and the method adopted was very simple, that is, to isolate Qian Yue and other sick people, and let someone send water and food, so that they would not have contact with other people.

But the matter didn't end there, another day passed, and the number of sick people increased from four to seven, and the other three had little intersection with Qian Yue and others on weekdays, but they were still sick!

The people of the Black Iron Mountain Villa were panicked and anxious.

"That's not right...... It doesn't seem to be some kind of plague, flu. ”

And in the evening of this day, after Su Changkong finished cultivating the Five Birds Opera, he took a kettle and poured two sips, but suddenly his heart beat slightly, and a faint sense of alarm rose.

"Poof!"

Su Changkong immediately spit out the water, and his face changed.

"Water source...... Is it a problem with the water source? ”

Su Changkong looked at the kettle in his hand, and his heart moved.

In the Black Iron Villa, there are seven people who are sick, but a few of them have basically no contact with each other on weekdays, and if there is one thing everyone does every day, it is to eat and drink!

And water is something that everyone must drink every day, and the reason why people suddenly get sick is because of the water source?

"Go to the owner."

Su Changkong felt the need to investigate from this aspect, so he immediately got up and went to the backyard of the Black Iron Villa to look for Mo Tie.

It was already evening, and in a room, Mo Tie frowned: "So many people are sick...... Is it the flu or the plague? Yesterday, I asked people to go into Qingshui City to find Dr. Liu, but when Dr. Liu heard about this situation, he didn't want to come to Black Iron Villa to see no matter how much money he gave. ”

Ordinary illnesses are not enough, suspected plague symptoms, ordinary doctors are like avoiding snakes and scorpions, for fear of getting into trouble, Mo Tie asked people to find doctors in Qingshui City, and those doctors only advised Mo Tie to isolate those who have symptoms, and never have direct contact with them.

"Bang bang bang!"

Outside, there was a knock.

"Come in, the door is unlocked."

Mo Tie, who came back to his senses, sighed.

"Branches!"

A tall young man pushed the door in, it was Su Changkong!

"Sky? Is there something coming to me for? Mo Tie was slightly surprised, Su Changkong was low-key, and he rarely took the initiative to come to him.

"Owner, there have been many people in the village who have been sick recently, is the root cause related to food and water?" Su Changkong didn't talk nonsense, and he got straight to the point.

Water and food, even Su Changkong must drink and eat on time, if there is a problem with these two, then everyone in the Black Iron Mountain Villa will have a problem!

"Right...... Water, go check the water source! ”

When Mo Tie heard this, his body suddenly shook, and he got up and said.

Originally, they had a preconceived idea that it should be something like the flu, but could it be that there was a problem with the water source?

"Lao Liu, ask the two of you to go to the back mountain with me and go to Heitiebo to have a look."

Mo Tie immediately found Director Liu and gave an order.

"I'll go too." Su Changkong was also ready to go to the scene with him, compared to not knowing anything, obviously knowing something to be prepared!

Mo Tie, Director Liu, Su Changkong and Mo Tie's two henchmen, a group of five people, headed towards the back mountain of Black Iron Villa.

Black Iron Por, this is a small lake located in the back mountain of Black Iron Villa.

There are hundreds of people up and down the Black Iron Villa, and the well must not be able to supply everyone's water, and this Black Iron Park is the source of water for the Black Iron Villa, whether it is drinking water, or the water used for forging and quenching, it all comes from the Black Iron Villa.

The lake is clear, and occasionally a few leaves float on the water, and the wind blows, making the lake ripple.

On the face of it, there is nothing wrong with Black Tiepo.

"Lao Zhang, go down and take a look."

Mo Tie said to a man.

This man's name is Zhang Shu, and he is good at water.

"Good!"

Zhang Shu nodded in response, he took off his clothes, shoes and socks, only wore a pair of pants, jumped into the black iron berth, and dived towards the bottom of the hoop to explore.

From time to time, he will pop up to breathe.

After a stick of incense, I finally found something!

"The owner...... Look! ”

And Zhang Shu poked his head out of the water, he shouted.

In Zhang Shu's hands, he was carrying a mouse!

A rat's corpse, to be exact.

Zhang Shu crawled to the shore and threw the mouse corpse on the ground.

This rat corpse is very strange, it is swollen with blisters, its hair is falling out, and there are small pustules protruding from its body!
