I originally thought there was a sun here, and there should be a moon, but the actual situation was that there was more than one moon at night here, but three, one silver, one blue, and one blood-red, which was very magical.

At the exit of the crack, Cao Hui and others climbed to the top of the tree and looked at the three moons above their heads curiously.

The 9 cave was also brightly lit, and they were also very curious about the three moons that Cao Hui photographed and transmitted back.

"Three moons? Is it so weird?" Feng Wuhen sighed.

"We are all connected to another world, just three moons. The atmosphere over there should be a little different from us. After the refraction of light, three moons of different colors appeared." Tian Ye guessed from the side.

"You said, is this other world in the same universe as our earth, or is it the so-called parallel universe?" Feng Wuhen said in a chat.

"No one knows this, but I guess it should not be a universe." Tian Ye replied.

"Why?" Feng Wuhen said in confusion.

Tian Ye smiled and said, "Although there is a sun and a moon in another world, have you not noticed any abnormalities?"

"What's the abnormality?" Feng Wuhen's appetite suddenly fell off by the other party.

"It has no stars, countless stars in the universe. It is logical that countless stars can be seen on any planet, but this world does not. Doesn't this tell the problem?" Tian Ye asked back.

"I really didn't notice this." Feng Wuhen was stunned.

Early the next morning, Hao Ren found Wang Meng and asked:

"Have Zhang Guotao returned yet?"

Wang Meng shook his head: "Not yet, it's been a night on the opposite side. Judging from Mr. Cao's situation, the forest at night is still relatively dangerous. I hope he can come back safely."

"We have no way to do it before we confirm whether the opponent is suitable for human survival." Hao Ren wanted to send someone to find him, but he couldn't do so, which would put more people in danger.

"I understand, please don't worry, Mr. Hao, I will put the overall situation first." Wang Meng was very smart and immediately understood Hao Ren's reminder.

Hao Ren nodded, said nothing, and walked to the temporary research center.

"What is the time difference between the two worlds?" Hao Ren asked.

"Mr. Hao, after one night of measurement, the time for one night on the opposite side is about 18 hours on our earth, and the day may be longer. No complete data has been collected yet. When the night falls again, we can confirm that there will be several hours a day there." The researcher replied.

"So, the day over there is much longer than ours." Hao Ren sighed.

Then he thought of something and asked: "By the way, through measurement, can we now determine whether the opposite side is the same as our earth?"

"Mr. Hao, this may be different from what we expected. The opposite side seems to be a sphere, but a round place similar to our ancient legendary sky and earth." The researcher said.

"How is that possible? Could it be that this planet is too big and our measurement range is too small, so the measurement is inaccurate?" Wang Meng said in confusion.

"Captain Wang, this is impossible. The larger the size of the planet, the higher the density, the larger the mass. If the opposite side is a sphere, then according to the data we measured, this planet is too large, at least hundreds of billions of times that of the earth. This is impossible. Such a large planet has great gravity. Our people have long been crushed into meat paste in the past, and such a large-scale planet has collapsed and cannot be formed." The researcher explained.

"According to you, if the sky is round and the place is round, it is impossible. Wouldn't such a square land collapse into a sphere?" Wang Meng asked back.

"Captain Wang talks about the key points, which is also a place we are very confused at the moment. Logically speaking, it is impossible to have such a world with a round sky and a place, but this is a different world, and it may not even be the universe where our earth is. Perhaps the rules over there are different from ours, so it is possible not to apply our previous scientific system." The researcher guessed.

The oxygen content in the air is nearly three times that of our earth. There is also a special element. The time of day is longer than that of our earth. There is a sun and three moons of different colors, which are full of differences everywhere.

"Mr. Hao, Captain Wang, and Zhang Guotao are back." The specialist who was responsible for video surveillance in another world jumped up from the chair excitedly and said.

"Let's take a look." Wang Meng rushed over and watched the surveillance video.

Sure enough, Zhang Guotao lived up to expectations and came back safely. He also brought a lot of things on his hands, which seemed to be a good harvest.

Hao Ren felt relieved when he saw Zhang Guotao coming back safely in the video and said:

"Let Zhang Guotao come back through the crack."

"Yes, Mr. Hao." The communicator transmitted the instructions here through the network cable connected to the two worlds.

Another world.

"Mr. Cao, Zhang Guotao is back." Wei Xiaoqiang said, pointing to the drone screen.

"Okay, I'll pick him up." Cao Hui glanced at the monitor, smiled slightly, directly unfolded his body, and ran towards Zhang Guotao quickly.

"Mr. Cao." Seeing Cao Hui appear in front of him, Zhang Guotao, who had just returned from the road, was on guard first and knew that it was Cao Hui who had relaxed.

"Let's go home." Cao Hui nodded.

"Okay." As soon as they returned to the crack exit, they were discovered by the earth.

"Zhang Guotao, Mr. Hao sent a message to ask you to return to Earth." Wei Xiaoqiang said.

"Okay, I happen to have a lot of things to report to Mr. Hao and the others." Zhang Guotao nodded, greeted the others, and returned with all his stuff.

"Huh?" Through the crack, Zhang Guotao appeared in a shed, and the entire space was instantly closed.

"Zhang Guotao, don't worry, the instrument is checking your body, you just need to cooperate." Wang Meng shouted.

When Zhang Guotao heard this, he nodded, relaxed, and made some strange movements as required by the staff outside.

One hour later.

"Professor Qian, how about it?" Hao Ren asked.

"His body has no effect. He should have eaten some food from another world before. His digestion is normal and there are no fatal bacteria on his body." Qian Siping said with a smile.

This was actually as expected by them. After all, ferocious beasts from other worlds have come to the earth many times. After decades, viruses and other things have already erupted.

They did this just to pursue scientific rigor, just in case.

"Haha, that's really great. It's basically certain that the other world has no bad influence on us humans. This is very beneficial to our next action." Hao Ren said happily.
