"Xianggong, your progress is really fast, is this the legendary no-trick win-win?" Yu Ling half-knelt on the ground, but he didn't expect that Qian Yunyue would become stronger than before in just a month, and the two fought against each other for only twenty rounds, and Yu Ling was defeated.

Qian Yunyue closed his eyes, feeling the aura between heaven and earth, without the constraints of the system, he was able to use any action he thought of more freely, that is to say, he had jumped out of the limitations of online games, he still remembered the movements of those sword moves, and after his own improvement, it was more convenient to use, although he could also feel the consumption of true qi in his body, but there was no such thing as any skill cooling.

The only problem now is that his physical strength is not as good as before, this is just a practice with Yu Ling, he is better in technique, and his actual combat power is not as good as before, if it is a battle of life and death, there is still no chance of winning.

However, he found a good place in the ancient city, which was probably used to train combatants in the past, and the gravity training room made with modern technology could not be better for exercising the body. Jade Ling followed him in once, stayed for half a minute and then ran away, vowing never to set foot in that place again.

The progress of cultivation is quite smooth, and the collection of weapons has been completed, but the information about the wall of life cannot be found, to be precise, it cannot be queried, and the system prompts that Qianyunyue's authority is not enough, and a higher level is needed to unlock it.

Qian Yunyue originally planned to find a way to pass through the barrier normally after understanding the principle of the Wall of Life, just like the instrument he used on the Sky Island at the beginning, but since it didn't work, he had to find another way.

"Xianggong, do you think you can climb over? There should be a limit to the height of that wall, right? ”

Qian Yunyue was stunned for a moment, this is a blind spot, he has not considered this possibility before, after all, he can't see the end at a glance, and his heart subconsciously thinks that it is impossible to cross, but after thinking about it, if he can climb over, the relative outside things can also come in, since he has not heard of similar news, then the possibility of going over the wall is very small.

"Let's go find a place to try it." Qian Yunyue's purpose has always been to act rather than to move, and the two of them prepared and came to the wall of life in the eastern part of the Ancient Realm.

"Xianggong, what is this?" Jade Ling looked at the device in his hand.

"It's called an oxygen mask, and it allows you to breathe in the air at a high point where the air is thin because you don't know how high the wall is, just in case you take it first, and put it on like this when you feel like it's hard to breathe." Qian Yunyue showed Yu Ling a demonstration, which he found from the warehouse, and they searched all the warehouses this month and found a lot of useful and good things.

The last time they went to the empty island, it was just over 10,000 meters, and they were still in the troposphere, and they could breathe normally with Qianyunyue's strength at that time, but if they reached the stratosphere or even above, I am afraid that the body would not be able to bear it, so they put on an oxygen mask to be prepared, their purpose today is to detect how high the wall of life is, even if they can really climb over the past, it is not yet time, and if you want to go to the outside world, you must be fully prepared first.

Because there was an enchantment on the wall, there was no way to climb, so the two of them directly launched light exercises and flew all the way up. When the Celestials who were in charge of guarding this area arrived, they were already thousands of meters in the air.

"Xianggong, the lines on this wall are so strange."

Qian Yunyue also discovered that the patterns that looked like spells seemed to have added something else on the basis of modern technology, but probably because of this, this wall could be so strong to protect the inner continent.

"Look, it's Yun." Although Yu Ling had been to Sky Island with Qianyunyue, she was still a sword spirit at that time, and this time she experienced it with her own body, and she felt completely different, and she was as excited as a child.

"Don't get too excited, be careful of not having enough breath." Qian Yunyue reminded that it is estimated that it has reached about 10,000 meters now, and the temperature has dropped a lot, although there is no problem for the time being, but it cannot be taken lightly.

"The wind here is so pleasant, I came up with a great idea." Yu Ling smiled, raised her hands, and a whirlwind formed under her feet, holding her steadily, "How is it?" That's a good idea, isn't it? ”

"Worthy of being the darling of nature." Qian Yunyue exclaimed, only the Celestial Clan can control the wind element so easily, but it can only play like this at this altitude, and it will not work any further, the stratosphere is basically free of water vapor, clear and cloudless, and there are few weather changes, and the wind is naturally rare.

"What does it smell like? It smells terrible. The jade spirit flew and suddenly wrinkled her nose.

"It's almost to the ozone layer, hurry up and put on the mask." Qianyunyue also smelled it, which means that they have broken through the troposphere.

Approaching the ozone layer means that it has exceeded 20,000 meters, and the air is thinner, but with an oxygen mask, there is no problem, but the temperature around it is getting lower and lower, and it is estimated that it is already dozens of degrees below zero.

"Xianggong, it's a little cold." Although Yu Ling listened to Qian Yunyue's true qi covering his body, he was still shivering from the cold.

Qian Yunyue hugged her tightly, and the two used each other's body temperature to warm up, it seemed that with the current situation, this was the limit, if they forcibly flew up again, they would definitely get frostbite, unless there were any antifreeze aids.

"That's all for today." Qian Yunyue glanced at the wall of life, and there was no end in sight, how did the human race build this miracle back then? But at the same time, he also understood that even if it was only to this height, there should be no one in this world to climb over, they were already considered to be one of the best martial cultivators in this world, and they were still small and powerless in front of nature.

"Xianggong, what should I do now?" The two returned to the city, took a hot bath, and finally recovered.

"It's impossible to climb over, we're almost done exploring this city, so let's try looking for other ruins." Qian Yunyue remembered that Uncle Hai said that there should be many relics of ancient civilization in the Ancient Realm, at least Taiqing Daozun had found one, otherwise he would not have a weapon like the electromagnetic pulse.

"Okay." Jade Ling is very happy, she is now very interested in this modern civilization, and the new ruins may have many interesting things.

"Prepare tonight, set off tomorrow, and Xianggong will take you for a ride." Qianyunyue repaired a flying car powered by electricity a few days ago, and with the battery found in the warehouse, it can be driven for at least two months. The storage space of the Blue Moon Ring is almost full, full of all kinds of materials and weapons, with these things, even if it dominates the entire inner realm, it is not too much.

"Ho ho~!" The two of them rode in the flying car all the way, and it was also because there was no one in the ancient world, so they could be so assured and bold to rampage, Qian Yunyue installed navigation on the flying car according to the map obtained in the system, and when he was tired, he could also drive automatically, in the words of his original world's Internet buzzwords: "Hi yo, I feel that my life has reached the peak." ”

"Xianggong, this flying car is so exciting, no matter how powerful the light work is, it can't catch up with this speed." Yu Ling felt that she was the happiest person in the world at the moment, and for tens of thousands of years, she should be the only one who had ever ridden a flying car.

Qian Yunyue was just holding the mentality of giving it a try, and chose a flying car that seemed to have the least damage, and then after some research through the information queried by the system, she didn't expect it to be repaired successfully.

I have to say that the central main system is really easy to use, just like an all-powerful search engine, except for the information of the wall of life, other information that cannot be queried has not been found for the time being.

According to historical records, there were hundreds of modern cities in the Ancient Realm, but most of them were destroyed in natural disasters, and only a few survived, and these are extremely developed countries with scientific and technological civilizations, as long as they can be found, they can definitely find useful information.

The two of them went all the way north, and spent about three days coming to a desert, which looked very desolate, not to mention animals, even few plants, if it was not a natural desert, it meant that it was an area that had suffered a disaster, so they began a carpet search, and finally found a broken ruin.

Compared to the previous Tianyu Ancient City, it is simply miserable, the buildings are basically only left with ruins, and there are many deep ditches in the city, it is estimated that it suffered an extremely strong earthquake, in this case, it is estimated that there is nothing left.

The two drove around the city, and were about to give up, when they suddenly found a well-preserved building.

"This house is so tall, and it looks so weird."

Qian Yunyue also felt the same way, in front of him was a black building dozens of meters high, he reached out and touched the outer wall of the building, this is not stone, but a special metal, which can stand tall in the natural disaster that destroyed the entire city, it seems that this building is worth exploring.

"Why is there no door?" The two of them walked around the building, but they didn't find the entrance, and the building couldn't even see a window, is this thing really a building?

When the two were puzzled, a burst of voices suddenly sounded: "Warning! Discover the intruders! The guards immediately went out to eliminate the foreign enemy. ”

"Guards?" Qian Yunyue frowned, he had a bad premonition.

"Xianggong!" Yu Ling exclaimed, only to see that a door suddenly opened in the seamless building, and a man in a black suit walked out, looking at the two of them expressionlessly.

"Robots?" Qian Yunyue was also stunned, he didn't feel the breath of a living person, and it was very likely that this appearance was mechanical. He hurriedly took out a round instrument and pressed the switch, which was similar to the one used by Taiqing Daozun before, it was a protective cover instrument, as long as it was not too powerful firepower, it could be resisted, although the two of them didn't care, but the flying car could not be destroyed. "Who are you?"
