Li Ran didn't hesitate too much and clicked the upgrade button directly behind his body.

"hiss……"

An extremely intense pain spread throughout his body. Li Ran felt that his muscles, bones, and internal organs were being torn apart and healed by an invisible force. Under this repetitive cycle, his body was constantly being lifted up.

"Oh my god, the improvement of my physical body and the improvement of my cultivation are like heaven and hell respectively!" Li Ran felt as if he had walked through hell.

"However, compared to the physical strength that is passively increased by cultivation, this is simply many times stronger!"

Li Ran felt a little shadowed in his heart, but he remained firm. Seeing that his physical body level had been upgraded to the mortal body level 1, a short message automatically entered his mind.

The whole body is as strong as steel. This is the characteristic of the physical body upgraded to the first level of the mortal body. The physical body upgraded by the true essence alone is far superior to the current physical strength!

"continue……"

After Li Ran's physical body was upgraded to the mortal body level 1, he found that in order to upgrade his physical body, he had to reach the skin refining level 1 in martial arts, so he could only click on the upgrade in martial arts!

After pressing the upgrade button of martial arts, Li Ran soon found that wisps of light red gas were emerging from all over his body, and then his heart kept contracting and expanding, beating several times faster than usual. As the beating accelerated, the light red gas was sucked towards the heart. When the heartbeat reached its peak and the gas disappeared, the heart suddenly stopped beating!

"Boo!"

Following a faint voice, Li Ran's consciousness, which was looking inward at his heart, was suddenly pulled into a small space. This space was about the same size as his dantian and was filled with some light red gas. After a moment of trance, Li Ran was returned to the place where his heart was pulled back!

After returning, Li Ran discovered that traces of light red gas began to appear all over his body.

At this time, a light red gas flowed out from the heart and spread throughout the body. All the light red gas flowed into the sea like a river. The airflow became larger and larger, and Li Ran felt that his whole body was swelling up. The skin all over his body became red as if it was burned by fire. In the process, Li Ran felt that his skin became more compact, delicate and tough!

During this process, the light red gas slowly decreased, while Li Ran's skin became tougher and tougher. When the light red gas disappeared, the tempering was finally over. When Li Ran thought it was over, a trace of Qi and blood power slowly emerged from his suddenly strengthened skin. Although the color of this gas was still light red, it was obviously darker than the previous gas!

"Is this power the Qi and blood force that allows warriors to compete with cultivators?" Li Ran looked at the light red gas in his body, somewhat confused.

He didn't dwell on it too much. Similarly, Li Ran discovered that if he wanted to upgrade his martial arts, there were requirements other than just the cultivation value!

To upgrade to the 2nd level of Skin Refining, one needs to reach the 2nd level of Mortal Body in physical realm. Combined with the previous requirements, in order to upgrade the physical body, one must cultivate to the 2nd level of Qi Refining!

"Damn, the cultivation speed is slow to begin with, and I have to upgrade my physical body and martial arts almost at the same time. I only have 8 points of cultivation value a day. If I want to reach 2, it will take at least half a month!" Li Ran sighed.

If Li Ran's expression of unwillingness and dissatisfaction with the slowness were seen by others and they knew the reason, he would definitely be beaten to death. You have to know that it takes others a long time just to get started at the first level, and it takes several days to consolidate after getting started!

And Li Ran had already become a first-level cultivator and warrior in less than half an hour...

…

"This is such a crappy system. It's substandard. They didn't even tell me how to trigger the message, leaving me to figure it out on my own. Ugh, a surefire bad review!"

After Li Ran finished complaining, he looked at his cultivation speed, concentrated his mind for a moment, and a piece of information appeared in his mind.

Li Ran learned from the information that the speed of cultivation is not only related to the cultivation level, but also to the grade of spiritual roots and the cultivation method.

His cultivation level could be upgraded by one level, but Li Ran did not continue upgrading because he could no longer control his body and he did not want to destroy his family!

…

whoosh!

A figure quickly rushed past Li Ran, and then disappeared without a trace in an instant. When he looked up at the sky, the corners of his mouth twitched!

"Waking up and returning home is fine, but what are those hovercars flying around in the sky? And why do those high-tech warships that only appear in science fiction movies keep popping up? Where's the fantasy world we were promised?"

Li Ran didn't know what to say. This world had completely changed...

Although the scene in the sky was awkward, Li Ran did not forget what he was here for.

Li Ran's father's school was very close to home. Although the world had changed so much, the road had not changed much. Soon, he arrived at the school gate.

When he saw someone walk in through the door, his eyes widened. Why did he need to verify his identity to enter the school? It was so frustrating. He didn't know if he could pass.

Li Ran hesitated for a while, and felt that he should be fine, so he decided to give it a try. It wouldn’t be a big deal if he couldn’t get in.

"…Checking identity…"

"...Inspection successful, allowed through..."

…

Although the world has changed, some things remain unchanged, and Li Ran successfully passed through the door.

The school was empty, with only a few people scattered around. This was normal because it was summer vacation and all the students had gone home.

“Bang… bang…”

Arriving at the track and field stadium, Li Ran discovered that the plastic track beneath his feet was somewhat unusual. He used a little force, but apart from a loud noise, the track was not damaged at all. When he increased his strength and even kicked it hard, the track did not change at all!
