Changsheng's sudden fainting startled Qin Yu, and he hurriedly stepped forward to check.

Changsheng's face was pale and his breathing was short.

Fortunately, Qin Yu had already prepared, and there were still a few oxygen cylinders in his ring, which happened to come in handy at this time.

When the oxygen cylinder is used, Changsheng still has no intention of waking up.

Qin Yu couldn't help but be a little anxious, he didn't dare to rashly give Changsheng the pill he had refined, he had no choice but to take him into the car and wait quietly.

Fortunately, it didn't take long for Changsheng to finally wake up.

He hadn't figured out what was going on, "What happened to me?"

Qin Yu was helpless, "You fainted just now, and it didn't help if I plugged in an oxygen cylinder for you." ”

"Looks like my body is about to run out. Changsheng is also very uncomfortable now, not only physically, but also mentally, he didn't expect that his body didn't hold on to this world for even a week.

It seemed so harmless, but it repelled his coming.

Qin Yu was also a little confused, there were many people from other worlds before, such as Yaoyao, and then the previous alchemy ancestor.

Even visitors from other worlds like Qin Feng stayed here, why did there be such a big problem here in Changsheng, this is a bit unreasonable.

However, it is estimated that even Changsheng himself did not understand this matter, and in the end, the discussion between the two ended without a problem.

Changsheng felt that he was feeling better, so he got out of the car again, ready to continue the survey.

Fortunately, this time his body held on.

He pulled out a very strange survey device, like a white cylindrical object, more like a crystal. He stuck something in the ground and started surveying the data with his own equipment.

He walked around the crystal, his face getting more and more ugly.

After half a day, he said slowly under Qin Yu's support: "I have already surveyed, and this is the most suitable one, but now my physical condition is unable to activate the device, I'm afraid you will have to wait a little longer." ”

Qin Yu wasn't in a hurry, he was more worried about Changsheng's body now, "It's okay, we can stay here for a few more days." ”

After the survey was completed, the two of them set up camp here, preparing to wait for Changsheng's health to improve before taking the final step.

Changsheng looked at the sky in the distance and sighed, "I didn't expect that in the end, I would be delayed because of my poor body. Don't worry, I'll turn it on by tomorrow at the latest. ”

After speaking, he took out the nutrients on his body and drank a bottle.

He slipped into his sleeping bag and rested, not even bothering about the view outside.

Qin Yu sat alone outside the tent, his chest feeling a little stuffy.

He always felt strange watching Changsheng become more and more fragile.

It's as if there was a person who came here because of him, but because he was getting worse.

Moreover, Qin Yu has seen the previous data, and this kind of damage is irreversible.

I really don't know if Changsheng will be able to live a healthy life after returning to his own world.

When he was leaving, he planned to take out some pills and give them to Changsheng, no matter what, let him take them back to study, maybe he could use them, sometimes the developed technology is not necessarily comparable to the ancient methods.

......

Changsheng slept until the next morning, and when he woke up, his face was pale, as if he had aged several years overnight. He was still wearing the white robe, but he wasn't as energetic as before.

Qin Yu's mood became a little heavier, "Your body can really hold on, right?"

"Don't worry, I know my own body, you can prepare, I will choose a time to turn on the device at noon today. ”

Qin Yu nodded, his face serious, "I know, is there anything I need to prepare?"

"You just need to prepare yourself, and when you time travel, you don't have anything on you, like your bag. ”

This was already expected by Qin Yu, "What about the clothes?"

"Don't wear any clothes yet...... There's no way around it, and when you get to the new world, you have to find a way to find a piece of clothing to wear. ”

Although Qin Yu felt a little embarrassed, he was not very worried, his acceptance ring was integrated into his body, and the time and space travel would not be affected, and there were just a lot of clothes prepared inside.

Seeing that Qin Yu was ready, Changsheng returned to the tent to do the data calculation.

As for the shuttle equipment, Qin Yu has not seen his true face until now.

As the minutes ticked by, the cold wind howled outside the tent.

Seeing that it was noon, Qin Yu's heart also rose, and Changsheng seemed to have set a timer by himself, and he had finished the calculation at exactly eleven fifty-five.

The strange thing is that he looks much better now than before, his face has returned to ruddy, and his whole mental state is completely different from before.

Qin Yu couldn't help but ask, "Did you take medicine?"

Changsheng smiled, "I didn't take medicine, I just used some unconventional means." Don't worry, you don't have to worry about my body, you come with me. ”

Qin Yu followed behind Changsheng and the two of them came to the place where the crystal was inserted before.

Changsheng said: "This place has the strongest magnetic field, and this time is the most suitable time to open the equipment. ”

He walked around the cylinder, then pulled something from his body that resembled what looked like a chip and inserted it into the crack on the side of the cylinder.

To be honest, Qin Yu really didn't notice that there was a card slot on this.

The card is inserted, and the cylinder cracks, revealing space for one person to enter.

Changsheng said, "You go in now, take off all the belongings on your body, and no metal can be left." ”

Qin Yu immediately took himself off and left nothing. He didn't have any surgery, and he didn't have any nails in his body.

Seeing that Qin Yu was ready, Changsheng made a final admonition, "When you arrive in the new world, you must protect yourself, and if you want to come back, take out this thing." ”

After speaking, he handed a very small black ball to Qin Yu, "If you want to come back, just press the trigger device on it, and it will be able to bring you back, open your mouth." ”

Qin Yu opened his mouth, Changsheng turned his head and threw the black ball into his mouth and swallowed it, "Only in this way is the safest." ”

It wasn't until the thing was swallowed that Qin Yu reacted, "This thing is also metal, won't it have an effect?" Also, how can I take it out?"

Changsheng shook his head, "It won't matter, this thing just feels like metal, but it's actually made of other supramolecules." If you want to take it out, drink plenty of water. Qin Yu, are you ready? I'll close this door in a while, and when you come out again, you'll be in another world. ”
