It was several hours later that Xie Xuan and Si Xun arrived at District 13.

It was already dark, but because of the time difference, they were still able to catch the ecological organization's dinner when they got off the helicopter.

The ecological organization treated this biological weapons experiment involving all residents of District 13 as its own large-scale exhibition. In the central tower in District 13, the only place that had not been infected by spores, it provided food and accommodation for the visiting members of the ecological bureaus of various districts and its own employees, waiting for the infection to begin tomorrow.

Xie Xuan and Si Xun were the last group to arrive, and they were greeted by a tall man with a very exotic appearance.

The man spoke a few words to Si Xun in the language that was once a compulsory course and is now the common language of the first four districts, and brought him to the restaurant.

Xie Xuan originally thought that under such circumstances there wouldn't be many types of food available in the restaurant, but she didn't expect that the huge restaurant was like a buffet, with all kinds of food lined up and available for anyone to take.

Specialty foods from each district can be found here, as well as a full range of wines, beverages and fresh fruits. If it weren't for the fact that she could see the high walls covered with mycelium in the distance through the window, Xie Xuan would even have mistakenly thought she was attending a cocktail party.

The ecological organization provided very considerate hospitality, but Xie Xuan felt an almost physiological aversion.

Si Xun obviously didn't like such occasions. He and Xie Xuan took some fried rice and hot dishes that were specialties of District 6. After eating, they left the restaurant to find their own room.

After leaving the crowded restaurant, Xie Xuan asked Si Xun, "What did that person just say to you?"

This cannot be blamed on Xie Xuan's lack of education. Before traveling through time, Xie Xuan had never even been to school, let alone learning a foreign language. After traveling through time, there was no foreign language subject in the compulsory education in District 6.

Because when the Human Confederation was first established, the various districts were not connected. Each district was separated by high walls and the land occupied by fungi between the walls, making it almost impossible for ordinary residents to travel between different districts.

Coupled with the limitations of the Internet, for ordinary residents, there is a certain degree of information isolation between the various districts. This is why District 13 was forced to give up its territory since last year, but has not caused panic in other districts until now.

Over time, foreign languages ​​were directly deleted from the compulsory subjects of compulsory education in the six districts.

Si Xun wasn't surprised that Xie Xuan didn't understand. "He said some people arrived three days ago, and there will be a cocktail party tomorrow night. A helicopter will be arranged to take us back to District 6 the day after tomorrow morning. And the biological experiment will start on time at 10 o'clock tomorrow morning. They will broadcast the entire process live on the top floor, so we shouldn't be late."

Xie Xuan was stunned for a moment, "Isn't the helicopter that brought us here from District 6?"

"It was arranged by the ecological organization." Si Xun said calmly.

Xie Xuan was stunned. "So not only do we not have a terminal now, and can't call for help from the outside world, but even our means of transportation back home is controlled by others?"

"That's right." Si Xun nodded.

Xie Xuan was silent for a few seconds. "What on earth made you choose to come to District 13 under such circumstances?"

"Because this biological experiment is crucial and may very well change the fate of mankind, District Six must participate in it," said Si Xun.

Xie Xuan understood Si Xun's sense of responsibility as the deputy director of the Sixth District Ecological Bureau, but her question was, "But why did you drag me into this?"

Si Xun turned to look at Xie Xuan, "You are not only a member of District 6, but also a member of the human race. Now you have a chance to control your own destiny. Are you going to just give it up?"

Xie Xuan was speechless.

The Central Tower was the center of the capital of the original thirteenth district. It was fifty stories high and had two elevator halls, each with six elevators.

Xie Xuan and the others pressed the up button. An elevator arrived first. When they got in and the elevator door was about to close, the elevator on the opposite side also arrived.

In her shrinking field of vision, Xie Xuan saw two familiar figures behind the open elevator door opposite.

The girl in the wheelchair in front, wearing a white dress and pure white hair, looked very much like Eve, the girl she had met in the zoo in District 6 before. Behind the girl, the person standing in the corner of the elevator looked a bit like Zhou Yuanyuan.

But the elevator door closed too quickly, and the person behind Eve kept her head down, so Xie Xuan couldn't actually see what she looked like.

The elevator started to go up, and Xie Xuan directly pressed the button for the next floor.

"What's wrong?" Si Xun asked.

"I seemed to see Zhou Yuanyuan." Xie Xuan said.

Si Xun frowned slightly, "Zhou Yuanyuan? Was she in the elevator just now?"

At this time, the elevator had stopped, the elevator door opened, and the elevator opposite stopped on the next floor.

Xie Xuan immediately pressed the button for the next floor again, and the elevator went down again.

"Are you sure?" Si Xun asked.

"I'm not sure." Xie Xuan said, "But I want to confirm it."

Si Xun didn't say anything else. After the elevator returned to the previous floor, Xie Xuan walked out quickly and Si Xun followed.

The elevator lobby is located near the main entrance of the central tower. There is only one direction to go after exiting the elevator, and the first place you pass by is the restaurant.

There was no shelter in the restaurant, and Xie Xuan could see everything from the door. Not only did she not see Zhou Yuanyuan, she didn't even see the girl in the wheelchair.

Xie Xuan immediately turned around and looked forward. In addition to the restaurant, this floor also had leisure and entertainment areas such as bars and gyms.

Xie Xuan searched everywhere but found nothing.

"Nothing was found." Si Xun did not doubt that Xie Xuan might have seen it wrong. Rather, it was precisely because they had not found anything that it was more clear that there was something wrong.

But now they are on someone else's territory after all, and Xie Xuan and Si Xun's actions have attracted the attention of others.

"Let's go back first." Xie Xuan said frustratedly, "Maybe I saw it wrong."

Si Xun and Xie Xuan returned to the elevator hall and went upstairs. This time they didn't see any suspicious figures.

The ecological organization arranged adjacent rooms for Si Xun and Xie Xuan. Both were standard double-bed rooms. There were communication devices in the rooms that could be used between rooms. All one had to do was enter the other party's room number.

The door had facial recognition, and Si Xun and Xie Xuan's facial information had already been recorded. Before entering, Si Xun said, "If you encounter any problems, please send me a message. We will meet here at 8 o'clock tomorrow morning. Any questions?"

"No problem." Xie Xuan said.

Si Xun nodded, and just as he turned around, he turned back and said, "Xie Xuan, we are on the same side, don't worry that I will hurt you."
