Let's suffer a little longer, fellow Blue Star folks.

If he hadn't found two blunt stone axes at the end, he would have thought he had found the wrong place.

"Strange, why would the inferior demons even take their bodies away?"

Normally, after killing humans, inferior demons would at most eat the human corpse on the spot.

Tang Yi had never even heard of anyone taking away human corpses.

unless……

"Were these inferior demons sent here by higher-level demons? So they have to bring back the bodies?"

Tang Yi squatted, looking at the faint traces on the ground, and his thoughts began to gradually diverge.

Could they be connected to the group of demons that Dr. Cai saw before?

Or maybe because Dr. Cai ran away before, so this group of demons actually came to find Dr. Cai?

This speculation is quite likely.

Considering the demons' nature of wiping out the enemy completely, it would be difficult for them to let a human who might have discovered their secrets live.

So Yu Shui and Chen Lu saved Doctor Cai's life?

"Um……"

Tang Yi stood up again, then turned and looked across the river.

It seems that I should go there when I have time.

"..."

"The leader is back."

Seeing Tang Yi's figure, Cai Cheng, who was originally counting the medicinal herbs, immediately stood up.

"How is it? Are there any herbs missing?" Seeing that Cai Cheng was a little nervous, Tang Yi patted his shoulder gently and sat down opposite him.

"Yes, they are all here." Cai Cheng nodded vigorously. "Now the patients in the city can be saved."

"That's good." Tang Yi looked at the cart not far away, then looked at Cai Cheng again.

"When is Doctor Cai planning to return to town?"

"Why don't we have lunch before leaving?" Xia Keyu also poked her head out from the simple kitchen.

Cai Cheng did not agree directly.

"It's okay, having a meal won't take too long." Tang Yi said.

"I want to go back with you when you leave."

"Where to go back to?" Cai Cheng asked subconsciously.

"Yunhe Town."

Chapter 15 Yunhe Town

In the afternoon, outside Yunhe Town.

The two men walked to the gate of Yunhe Town, and the guards naturally came to greet them.

"It's me, it's me." Cai Cheng quickened his pace a bit, then said to the guard with a smile, "I just left the city this morning. I think you still remember me, General."

"Ah."

The guard nodded expressionlessly, then turned to look at Tang Yi behind Cai Cheng.

"What about him?"

"He is a relative of mine who lives outside the city. I brought him into the city to help. As you know, my clinic caught fire yesterday. Plus, I have an injury on my hand, so it's not very convenient for me to do anything." Cai Cheng also explained immediately.

The guard nodded, then looked at Tang Yi again.

"Okay, just pay the entrance fee and go in."

"Okay!" Cai Cheng immediately took out six copper coins from his pocket and handed them over.

Because copper is the most cost-effective metal for conducting 'gas', it has retained its fundamental value in this era.

Naturally, this currency with the same name as Blue Star has become a common trading unit in this world, just like Air Stone.

However, due to the large amount of reserves and the fact that it is not as precious as the Air Stone, its monetary value is much less than that of the Air Stone.

In other words, one or two Qi stones can be exchanged for about one hundred copper coins.

The guard took the copper coin, put it into a machine for verification, and then waved his hand to signal Cai Cheng and Tang Yi to pass.

The two men immediately pulled the cart into the city gate.

The area near the city gate is relatively clean, and the avenue leading directly to the town center seems to be swept frequently, and the houses on both sides are mostly exquisite.

However, as Tang Yi and Cai Cheng walked towards the left side of Yunhe Town, the houses on the road gradually began to become dilapidated. Some of them were not even wooden houses, but shacks supported by a few wooden sticks and some rags.

And there is an indescribable smell in the air here.

On the bumpy stone road, you can often see people carrying woven bags or bamboo baskets. Most of them are pale and thin, dressed in tattered clothes, and their eyes seem to be looking ahead, but without any spirit.

They are scavengers in Yunhe Town.

Their daily job is to go out of the city and scavenge nearby. Their targets are usually some valuable plants, some scattered fragments of equipment from pre-war civilizations, and the bodies of some unknown passers-by.

Because unless people are killed by humans, wild beasts and demons will not take away the property they carry.

Naturally, these corpses became the "garbage" that scavengers most hoped to encounter.

"Things of yours are worth only one or two Qi stones at most."

"Impossible! I still have a 90% new long sword here. You have to give me at least three taels!"

The sound of two men came from the corner. Tang Yi looked over there and then looked away.

Yes, this is how scavengers exchange what they find for money.

Merchants would come to this area from time to time to collect goods, but they would keep the prices very low.

"Ninety percent new? Don't think I don't know, this is something from a dead person! And I can only give you one or two Qi stones just for this knife!"

"Forget it, I'll give you some more, one and a half taels. If you don't sell it, I'll go buy it from another store."

"Selling... selling... can you give me more? Even two taels is fine. My daughter is sick..."

"Difficulties! Everyone has difficulties! If you have difficulties, don't I have any? It's just one and a half taels. Hurry up, I don't have time to waste here with you. After I leave, I wonder who will come to your house to collect this broken knife!"

"Okay, okay, one and a half ounces is enough..."

As the two walked away, the sound in the corner gradually disappeared.

Cai Cheng's home is in the northeast corner of the city.

The houses in this area are quite neat. Some of them have stone walls outside, and some even have yards.

"Did something happen to that family?" Tang Yi asked, looking at a relatively luxurious house not far from Cai Cheng's house.

"Oh, that one." Cai Cheng looked in the direction Tang Yi pointed and immediately replied with understanding.

"It seems they have hooked up with a noble in Cloud City and just moved into Cloud City a few days ago."

"Is that so?" Tang Yi nodded slightly.

He remembered this family.

Because he had seen the owner of this house, an old man with kind eyes and a sage-like demeanor, and he often helped the neighbors nearby. Perhaps Cai Chengdu had received his favor.

It's just a pity...

He is a big demon.

"Moved to Cloud City..."

After Tang Yi helped Cai Cheng push the cart into the house, he came back out and continued to look at the big house.

Why did it suddenly leave Yunhe? Was Yunzhong City its original destination?

Or did something happen in Yunhe?

……

Not long after, Cai Cheng also came out of his house, carrying a medicine basket on his back. However, from the gaps between the bamboos, it can be seen that in addition to the herbs he collected in the valley a few days ago, there were also some other herbs in it.

"What are you doing?"

"Oh, because the medicinal herbs have been found, I plan to send them to the patient." Cai Cheng said this and remembered that he seemed to have not told Tang Yi about the strange disease, so he also told Tang Yi about what he had encountered during this period.

"Strange disease..." Tang Yi frowned, "When did this strange disease appear?"

"Just a few days ago."

"Is there a more specific time?"

"Uh..." Seeing Tang Yi's serious expression, Cai Cheng immediately recalled.

"The first patient had an attack five nights ago and died the day before yesterday."

Hearing this time, Tang Yi's heart sank.

Five days ago was the day he killed Xia Keyu's 'father'.

"Do you have a list of all the patients?"

"There was one before." Cai Cheng's face was a little bitter when he said this, "But because the clinic caught fire the day before yesterday, the list was also burned."

"But I'll ask another doctor and they should be able to make a new one."

"Okay, then I'll leave it to you." Tang Yi nodded.

Because he had something to do in Yunhe Town today, he temporarily separated from Cai Cheng here.

According to his memory, Tang Yi walked to a fairly magnificent building in the center of the town. There was an old plaque hanging at the door with three large characters written on it.

Yunhe Hall.

This shop is opened by the mayor of Yunhe Town, so the location is excellent. However, perhaps because there are not many people in Yunhe Town who can come here to consume, the store seems a little deserted.

This was Tang Yi's first time coming in as well.

Before, he came and left Yunhe Town in a hurry and did not have the chance to visit many places.

He took a quick glance at the merchandise area and suddenly saw a familiar long knife, which seemed to be the same style as the one the merchant had just collected from the scavengers in the slums.

The selling price is also written on it.

5 taels.

Tang Yi's gaze did not linger.

He turned around and walked straight to the sales area.

Through the screen, there was an old man sitting behind the table, bored. When he saw Tang Yi coming, he stood up slightly and sat up straighter.

"What are you selling?"

The old man's tone was lazy and his attitude didn't seem like that of a businessman at all.

"A long knife."

Tang Yi handed over the standard long sword that he had taken out from the system in advance.

"Yo."

When the old man saw the thing, he sat up a little straighter and stretched out his hands to take the long knife.

Then he looked at it carefully for a while, and then gently touched the blade with his wrinkled fingers.

"Ninety-nine new."

The old man took out a piece of silk from the drawer in front of him, slowly placed the long knife on it, and then looked up at Tang Yi again.

"This is the standard long sword of the Allied forces. It's very well preserved. How much do you want to sell it for?"

Is this the standard long sword of the Allied Forces?

Tang Yi's eyes subconsciously glanced at the long sword, and then looked at the old man again.

"120 taels of Qi Stone." He didn't hesitate much, and his tone didn't change much.

"120 taels..."
