Medical mountains and rivers

After doing all this, Song Chengqing hurriedly caught up with Fang Lei and the others.

The road in front of the old house was under construction, and it took some people a long detour to arrive.

The house in front of it has a strong local style, and it is still well preserved. The door has been damaged, and when you step in, you will feel a dull breath.

Song Chengqing turned around, covering his head and face with cobwebs, but still found nothing.

Sixteen's excited voice suddenly came: "Sister Fang, come quickly!"

When the four people who heard the sound arrived, he was facing the wall and bowed his head, seemingly fiddling with something in his hands.

"Sixteen." Fang Lei walked over, "What did you find?"

Withered creepers were crawling there, turning a piece of courtyard wall into yellow-green, Shiliu turned his body sideways, and a small area that had been cleared out was revealed in front of everyone.

It turned out to be a door.

"Can it be opened?"

Sixteen shook his head.

The old-fashioned lock has rusted into the iron door unless it is violently damaged.Otherwise, you can only climb over the wall.

Everyone unanimously chose the latter.

There are a few rooms standing alone behind the door, with a stone pool in the middle. The wooden shelves piled up on the west side have decayed. Dozens of large tanks fell on the ground in disorder, becoming a nest of snakes, rats and ants.

Song Chengqing took a quick look and said, "So that's how it is. The front is the cloth shop, and the back is the dyeing workshop."

He walked into a room at random, feeling that he had gained nothing, and was about to leave when he suddenly noticed something beside the two tanks in the corner.

"Ok?"

When he took a closer look, it turned out to be a paintbrush, which had fallen between the cracks and was covered in dirt. No wonder the owner didn't want to pick it up.

"What did Mr. Song find?" Da Fei walked in.

"It's a good thing." Song Chengqing moved the vat away, picked up the paintbrush and wiped it clean. "Come and see."

This is a common brand pen on the market. It can be seen that it has not been used a few times. The barrel of the pen is smooth and brand new, and the tip is engraved with a word "Swallow".

Da Fei took it and looked at it carefully for a long time, finally scratched his hair, resigned and said: "Mr. Song, I only see that it belongs to Team Yan's younger brother, other things are not enough, you should tell me directly."

At this moment, Fang Lei and the others heard the movement and walked in one by one.

"what are you guys saying?"

Song Chengqing handed the pen to the crowd, rubbed the nib, and the solidified paint on it fell into his fingertips.

"I found out that this pen is not dipped in paint for painting." He laughed, "It's dye for dyeing cloth."

what! ?

Several people quickly took the brushes, frowned and looked carefully, but they were all pure laymen in terms of painting and weaving and dyeing, and they couldn't tell the difference between the two at all.

Fang Lei said solemnly: "At least we can be sure that the four of Yanliang have been here." She couldn't help but frowned, "Chen Manman and the others didn't mention it, did they hide it on purpose or did they really not know?"

The former will affect their subsequent course of action.

The latter indicates that the four of Yanliang may have returned to the old house again after they separated, and here may be the key to the disappearance of the four.

"Yanliang is an art student, so it is impossible not to carry painting tools with him." Song Chengqing recalled that when they met for the first time, the young man was carrying a large drawing board on his back. "But why would he give up professional paints and choose something else?"

The only possibility is that the thing is weird.

The rest of the people also reacted and looked around for possible remaining dyes.

Soon there was a discovery.

On the wall of the big vat that Song Chengqing pushed away just now, there was a thick layer of slurry, which was obviously deposited from the leftover dye.

He stretched out his hand to scratch a little, and the color was slightly yellow, almost the same as the color on the pen tip.

... Well, it smells pretty good.

Da Fei carefully took a fingernail-sized piece, sprinkled it on the broken pottery, poured water from the kettle to melt it, and muttered, "No matter how you look at it, it's just an ordinary dye."

Song Chengqing couldn't see any problems for a while, so he said casually: "Go back and study a little bit first, and bring the pen with me. I'll see if I can find Yanliang's position along it."
