In June of the 419th year of the Recovery Calendar, the Dawn Train rose to three stars.

In August of the 422nd year of the Recovery Calendar, the Purple Flame and Jinghong Train were successively promoted to three stars.

In January of the 423rd year of the Recovery Calendar, the Tiangong and Yuegong trains simultaneously rose to three stars.

As for the Bubble and Phantom Trains, it took another ten years for them to be upgraded to higher stars, lagging far behind other trains.

After that, the auxiliary trains imitated the design of the main trains and built cities one after another, which continued to cause frenzy among passengers.

Changes inside the train do not affect the external voyage. The eight trains wander around, repeatedly collecting resources and building trains, and there is no end in sight.

Chen An was almost completely idle. Apart from enjoying himself every day, he just strengthened his body and used the throne to help others strengthen themselves.

Finally, with his unremitting efforts, Qianqiu broke through to the ninth level in the 436th year of the Recovery Calendar, and barely had the ability to compete with Chen An.

But if Chen An becomes giant, Qianqiu still can't defeat him.

Then time flies, and fifty years have passed in the blink of an eye.

The third level of urban infrastructure has been completed and is fully open to qualified passengers.

But as Chen An expected, the occupancy rate could only reach half, and the vast majority of passengers could not get enough contribution.

Therefore, the train continues to add daily tasks, striving to have passengers qualify every day and use this as an example to motivate other passengers.

In addition, Qingyue became too big to stay in the zoo and was officially taken away by Doris.

Although Qingsui was reluctant to leave, there was no other way. The Suxing Clan would be so big that even the train could not accommodate them, so it was important to adapt to the starry sky environment as soon as possible.

When leaving, Chen An was also present.

"Uncle, isn't it fun outside?"

Qingyue is still a chubby ball like when she was a child, but she is not disgusting, instead she looks cute.

Chen An reached out and touched it. It was plump and elastic.

"Whether it's fun out there is up to you. Aunt Doris will teach you basic survival skills."

Although he said he was going outside, he was actually still next to the train, but he would live on Doris's platform for a long time.

Qing Sui said sadly, "When I was little, I always liked to sleep on her. It will be difficult in the future."

Chen An said: "It's not a life-and-death separation, it's just a change of living environment. If you like, you can go out and see her at any time, no one will restrict you. Qingyue, don't you agree?"

At this time, Qingyue was equivalent to the size of two frigates, and only the defense layer could accommodate it.

She nodded repeatedly with an innocent look in her eyes.

Qingyue and Qingsui are standing at different angles, so their feelings are also different.

In Qingyue's opinion, she was just going out to play, not much different from before.

After a few more instructions, Qingyue left the cabin and was taken away by Doris's tentacles.

"Why are you still not happy?" Chen An saw Qingsui was depressed.

"How can I be happy? In principle, the inside and outside of the car are very close, but in reality, there's a world of difference between the car door and the outside. Forget it, I'll continue to cultivate other creatures! It's a pity that I can't cultivate more Suxing people."

Based on the experience of cultivating Qingyue, Qingsui and the Biological Research Center continued to conduct experiments, but they were never successful again.

“Don’t force it, just let it happen.”

Qingsui gradually calmed down and asked, "Is Xiaoxiao awake?"

These words reminded Chen An, and he slapped himself on the forehead.

"I almost forgot about the little guy. Come with me and take a look."

Chen An took out the throne and asked Qingsui to come up as well.

One advantage of the throne is that no matter how many people sit on it, they can teleport along with them.

However, Qingsui is a bit big, and when Chen An sits on it, he looks like a little kid.

"Brother An, did you get squeezed?"

"fine."

With a thought, the throne disappeared in an instant and appeared in the botanical garden the next moment.

The place is full of chirping sounds of spiritual plants, it is very lively.

"Xiaoxiao is about to break out of her cocoon. I wonder what she will become."

"Will it turn into a butterfly? I think it's very likely."

"Oh, the conductor is here."

Crash...

Woo woo woo…

Strange noises were heard everywhere, which were regarded as a welcome ceremony or a gesture of goodwill to Chen An.

Chen An said: "Don't worry about me, just have fun."

He and Qingsui left the throne and flew to the core area inside the woods.

The huge trees rose straight up, their tops almost touching the roof of the car.

"Manman's body is almost out of space. I guess it will have to be moved out soon."

"Move it to Doris?" Qingsui asked.

"Yes, she's the only one who can carry it. But I hope Manman can survive independently, which will be more flexible and convenient. There's another problem with leaving the train. It's difficult for me to provide her with the best protection."

Qing Sui chuckled: "You said before that I couldn't bear to part with Qing Yue, but aren't you also reluctant to part with Man Man?"

"That's different. It's not that I'm reluctant to let her go, but I'm worried about her safety. After all, no one knows what kind of harsh environment the train will enter. It's definitely safer to stay inside. It would be great if there was a space that could accommodate living things."

The two chatted as they came under the tree, where Luoyu and Manman were in their human forms.

"Dad, Xiaoxiao has worked so hard." Manman threw herself into Chen An's arms.

"Where is she?"

Luo Yu pointed to a tree branch where a colorful cocoon was hanging. A dark shadow was struggling inside, and it really looked like it was having a hard time.

Manman asked: "Should we help her?"

"Don't disturb her, let her come out on her own." Luo Yu said with a serious face.

Chen An looked closer and seemed to see small eyes, which were very beautiful.

She blinked at Chen An, not in pain, but in joy.

"She's fine, just wait!"

When they were free, Qingsui and Manman went to play in the woods, while Chen An and Luoyu walked around, studying new spiritual plants and discussing the development of the train.
