Xu Tian decided to go up the stairs, although Mr. Jin dissuaded Xu Tian, Xu Tian always had a strange feeling in his heart, as if he felt that he could see the woman who looked exactly like Sitong when he walked up the stairs.

The staircase is circling, from the first floor, you can see that the staircase is about six stories long, and the entire hall on the first floor is also as high as a six-story building, and from the outside you can see that the building is seven floors, which means that except for the hall on the first floor, there is only one floor after climbing the spiraling staircase, which is very similar to a shopping mall.

When Xu Tian climbed the stairs, he noticed that there were only a row of dirty footprints under his feet, and it seemed that only Kang Yuliang had climbed the stairs alone.

But Xu Tian felt that if the woman had been in this building before, then she might not have left footprints on the stairs.

For the sake of safety, when the people who climbed below couldn't see him, Xu Tian simply lay on the stairs, and Xu Tian smelled the smell on the stairs like a police dog.

But most of the smell on the stairs is formaldehyde, and there is a little fishy smell.

Formaldehyde should be the reason why the house was built not long ago, and the fishy smell was left by Kang Yuliang's dirty footprints.

Kang Yuliang should have walked in a very dirty place for a long time before he came in, his shoes stepped on a lot of mud in that place, and then walked into the house after a period of snow, and when he went up the stairs, the snow on the soles of his shoes gradually melted, and the snow melted into a paste, so Kang Yuliang's footprints stuck to the stairs.

But the smell that Xu Tian wanted to smell was the fragrance of a woman, because when Xu Tian saw the woman just now, he obviously saw that the woman was not wearing shoes, she was barefoot.

If the woman climbed the stairs barefoot, it would inevitably leave a fragrance, but the formaldehyde smell and fishy smell were too strong, and Xu Tian couldn't smell the other smells at all.

Xu Tian quickened his pace and walked up to the seventh floor, at this time, Teacher Jin lingered downstairs for a long time, and felt that it was a little unsafe for Xu Tian to go up by himself, so Teacher Jin also followed.

Xu Tian, who was the first to climb to the seventh floor, didn't see Kang Yuliang, this seventh floor was almost as decorated as a shopping mall, and almost all the upstairs were undecorated cubicles, which looked like he was preparing to open a shopping mall here.

Xu Tian saw that there were still piles of cement in some compartments, and when he looked closer, the cement was still wet, which indicated that there should have been workers working here before.

Xu Tian looked at the time, it had been about an hour and a half since they entered this building, so the workers should have left a short time before they came in.

"Did you find anything? Kang Yu is like a good hidden. Teacher Jin walked up the stairs and said.

At this time, Xu Tian hadn't gone far, he didn't go forward quickly as soon as he came up, but kept trying to observe every place, so Xu Tian hadn't gone too far when Teacher Jin walked up.

"The workers here have been working, but it seems that the workers have all withdrawn shortly before we came in." Xu Tian said.

"That means that the work here has been rushing, and now it's winter, and the buildings on the periphery have basically stopped, and it's normal for them to change to renovate the interior." Teacher Jin said.

"This shouldn't have been prepared for us people before, it's like a temporary location, otherwise it wouldn't be possible that the upstairs hasn't been renovated." Xu Tian analyzed.

"The only place that can be used on the high mountains of Caogang Village is this building, but you have some truth, because of the heavy snow blocking the mountain, everyone can't go down the mountain, and in Caogang Village, if you want to lock everyone in a sealed space, it won't work in the village, so only here is the most suitable." Teacher Jin said.

"Li Zhitong's subordinates have police dogs, and if you want the police dogs to search here, you only need to use a little means, so you can successfully lure Li Zhitong here, and then we followed Li Zhitong here, it should be like this." Xu Tian said.

"It seems that the person who brought us here is still very knowledgeable about the whereabouts of all of us." Teacher Jin said.

"There should be people among the villagers, we thought the village was a little strange before, except for Yingfeng's father and daughter who live alone and Mr. and Mrs. Xu, we haven't seen anyone else in the village traveling with their wives, so those villagers must have a big problem." Xu Tian said.

"We'll still meet Lao Gao and Lao Ma, as well as that troupe, don't worry too much now." Teacher Jin said.

Xu Tian and Teacher Jin were talking when they suddenly heard the sound of glass breaking, and the two hurriedly ran in the direction of the sound.

The voice came not far away, it was in an unrenovated cubicle, and when Teacher Jin and Xu Tian arrived there, they found Kang Yuliang pushing a young man in work clothes out of the window.

Kang Yuliang's movements were very neat, but Xu Tian still saw a rope around the young man's waist.

"What are you doing? Push the renovation workers down? Why not let them go down the stairs? Xu Tian stepped forward and asked.

Kang Yuliang was not nervous, such a calm Kang Yuliang made Xu Tian feel a layer of pressure, which was completely similar to the Kang Yuliang he had seen in the Shanghai hospital before.

Kang Yuliang didn't answer Xu Tian's question, but packed up some tools on the ground and threw them all out the window.

"Hey! What do you do if you hit someone? The workers are still down there, right? Xu Tian shouted.

"If you can't kill anyone, they all scatter to the side, and no one will be stupid enough to go straight down the wall." Kang Yuliang said.

"Why are you doing that?" Xu Tian asked.

"The workers are off work, I dismiss them, is there a problem?" Kang Yuliang replied.

Kang Yuliang's words made Xu Tian have no temper, and now Kang Yuliang looks righteous, and he doesn't look at Xu Tian and Teacher Jin at all, but Xu Tian and Teacher Jin can't do anything with him, after all, Kang Yuliang has not done anything illegal and criminal in front of them.

As for the workers with ropes tied around their waists, Kang Yuliang can also say that they are repairing the periphery, after all, the workers have ropes wrapped around their waists.

"It's almost time to eat downstairs, and the rooms upstairs are very limited tonight, and some people want to sleep in unrenovated cubicles, or stay on the first floor to keep vigil, how about it?" Are you two people who can contribute? Kang Yuliang said in a mocking tone.

In this regard, Xu Tian and Teacher Jin can indeed make concessions, and staying on the first floor to keep vigil is exactly what Teacher Jin thinks, after all, there are all bail prisoners here, and Teacher Jin is very insecure.
