Although that's what she said, Yi Qiuling had some bitterness in her eyes.

It may not be too long for them to be out of touch with the real world, but God knows how long they will be trapped here?

After Su Yuan and Zhang Ziqing came to Yuanfu, Chu Feng explained that they would come to Yuanfu at least once a day to report the real world situation, in the form of paper and pen. If there was anything important, they would write it down with paper and pen and send it back to Yuanfu.

It's not that Chu Feng is very concerned about his control over dawning city.

In fact, it happened more than once that Chu Feng left the city of dawn for a month or two. Now that he has been away for only a few days, no one feels abnormal.

What he worried about was whether the enemy would take the opportunity to attack dawning city after he was trapped here.

If the person who trapped himself here is also his own enemy, it is very likely.

However, for three consecutive days, there was no abnormality in the city of dawn.

Su Yuan did not immediately block the news that Chu Feng could not return to the city of dawn, but pretended that everything was as usual. Anyway, the people in the city of dawn were used to the disappearance of the Lord.

As long as the equipment forged by the ancient Chinese and the grey dwarves is continuously transported from the Yuan government, the people of Dawning city will be full of confidence in the future of Dawning city.

However, three days in the real world is 36 days in the mysterious space.

In these 36 days, Chu Feng occasionally entered the yuan house to check the situation, but Yi Qiuling had nothing.

Beside her, Chu Feng was the only one.

In more than a month, Chu Feng and Yi Qiuling made all kinds of attempts. They tried to destroy the ground and ceiling here, but in vain. On the contrary, they spent a lot of money for no reason.

So after trying for a while, they gave up.

Chu Feng summoned a long abandoned armored car from the yuan mansion. It was the booty he collected from Jinling creature. With his strength gradually enhanced and the popularity of hell nightmare horse, the armored car had been abandoned, but it was not scrapped because it was in the yuan mansion.

The weapons on the armored car have been removed by him, so the mobility has become much bigger.

Now Chu Feng and Yi Qiuling are sitting in an armored car, and they keep flying away every day. There is no need to worry about the fuel problem. In Chu Feng's Yuanfu, they have eliminated more than one gas station.

Because he was too bored in the car, Chu Feng studied the engine again, and asked Su Yuan to entrust the military to ask for a drawing of the rocket and high-speed rail power system. Then, with the help of Yuan Lingdao's computing power and Tiandi seal, he transformed some special armored vehicles.

Now, the speed of Chu Feng's armored car has reached 1200 per hour.

fortunately, the shell of the armored car has been replaced by the material of black iron and black iron alloy. Otherwise, the armored car may burn just because of the friction with the air.

It is worth mentioning that although the rules of the world are different from those of the earth, they are also very similar. The air also contains oxygen, and the content is similar to that of the earth.

This is more than a month of travel, let Chu Feng some irritable.

For a month in a row, what he saw was the same scene, which really made people crazy. It was that Chu Feng was able to communicate with the real world through Yuanfu.

Yi Qiuling, however, watched the boring scenery for more than a month.

Chu Feng is not the kind of person who can chat with others to relieve boredom, so he doesn't know how to comfort Yi Qiuling. Fortunately, Yi Qiuling is meditating most of the time, and the interference is not serious.

A month later, Chu Feng stopped to look at the traces on the ground.

After checking, Chu Feng began to turn around. After a while, he stopped at a place.

"Did you find anything?"

Yi Qiuling asked with expectation in her voice.

In this more than a month's time, two people are almost repeating the same thing, now Chu Feng suddenly has such a strange move, of course, she is full of expectations.

"Unfortunately, this discovery is not a good thing."

Chu Feng inserted the ChiYan sword at his waist into the ground, but it was not hindered, because there was a groove here, which was just able to hold the ChiYan sword.

"When we were walking just now, I scanned the ground with mental energy for 4 weeks and found that there were some slight marks on the ground. Although they were not obvious, they were obviously different from the surrounding environment. After careful observation, it turned out that they were the marks produced by the burning of gasoline."

Chu Feng's reply let Yi Qiuling feel very disappointed, "I went back here along the opposite direction, and found the sword mark that I left here at the beginning, that is to say, we went back to the origin again in this month."

Yi Qiuling was silent for more than ten seconds before she said slowly, "is this a round ground similar to the earth?""Maybe, maybe not. After all, we have a ceiling on our head. If the ground under our feet is round, the ceiling on our head should also be round. If the ball is too small, we should be able to irradiate an arc-shaped surface when we irradiate it in the distance with strong light, but this is not the case."

Chu Feng shook his head, "people's left foot and right foot will have errors, the car's left wheel and right wheel will also have errors, even after modification, let the error infinitely close to 0, but after all, it can't really be 0, can't walk completely along a straight line, so even if we walk in the same direction, a great probability will return to the origin."

Yi Qiuling was silent and disappointed. It was not her first experience.

In this month, she thought about countless ways to leave, but in any case, she could not think of how to leave here.

Here seems to be an endless cage, people can not escape.

Even if it's broken, you can't find the kind of fence.

"If there is no way to escape from the distance, maybe we can do it in another way, that is to break the space with direct force."

Seeing the gloom in Yi Qiuling's eyes, Chu Feng comforted, "those who are strong in the holy steps can directly break the space with their strength. What's more, I have a sense of space. Although there is no scenery here, there is still plenty of vitality, so it's OK to cultivate. If we can cultivate to the holy steps, we can break the space, even if we enter the space and leave If I open here, at least I can find my Yuanfu coordinates and go back to the original world. "

After listening to Chu Feng's words, Yi Qiuling didn't have much fluctuation.

She is not the kind of young people who are enthusiastic after one or two words of encouragement.

Looking at the stereotyped scenery around, Yi Qiuling frowned slightly: "I always feel that this should not be the real way for us to leave this space."
