Chen Cao felt that his one-month stay in Hetu had not improved in other aspects.

The speed is much faster, in order to pass through the Ice Domain and the Sky Fire Domain as quickly as possible.

Chen Cao kept accelerating, and then accelerating.

Together, the Ice Domain and the Sky Fire Domain are a circle of about six kilometers.

Originally, it took about three minutes for Chen Cao to complete the race, but now Chen Cao has shortened it to two and a half minutes.

At this speed, the speed is about 140 kilometers per hour.

At the same time, Chen Cao's control of spiritual power is also more handy.

Chen Cao knew how to maximize the use of spiritual power.

It's not the maximum spiritual power output from the beginning.

As a result, after holding on for less than a few laps, the spiritual power was exhausted.

Chen Cao can now run 20 laps in one go.

After a month, Chen Cao didn't know how many laps he had run.

"Chen Cao, now you try not to use spiritual power to protect your body, and you can insist on running a few laps. ”

"Do you want me to freeze into a popsicle? or do you want me to bake it?"

"If the cold and heat of Xuan Bing and Tianhuo don't enter your body, you will never progress, just endure it and it will pass. ”

"Why don't you stay with me?"

"I don't need to be transformed, why should I suffer with you. ”

Chen Cao stood in front of the Xuan Ice Realm and the Heavenly Fire Realm again, and did not use spiritual power to protect his body.

Chen Cao took a deep breath and plunged in.

With spiritual protection and without spiritual protection, these are two completely different concepts.

Chen Cao felt a chill as if it was about to penetrate Chen Cao's body.

No, my body is going to freeze.

All blood seems to stop flowing.

Chen Cao felt that his body was getting slower and slower.

No, speed it up!

The moment Chen Cao broke through the Xuan Ice Realm, a heat wave poured into his body.

Chen Cao's speed suddenly accelerated, and the original cold in his body became Chen Cao's protection at this time.

Chen Cao's heart moved, is this the trick?

Absorb the cold first, and then use it to withstand the heat wave of the Heavenly Fire Realm.

But halfway through the run, the cold was gone.

Then the heat flow began to pour into Chen Cao's body faster.

Chen Cao did not stop the heat flow into his body this time, but directly let the heat flow in his body.

The moment he rushed through the Heavenly Fire Domain, the heat flow began to resist the chill of the Xuan Ice Realm outward.

Cold and heat restrain each other, and heat and cold are also constantly acting in Chen Cao's body.

Chen Cao's speed was faster, and Chen Cao felt that he was adapting.

The role of the golden key is working.

Chen Cao felt that his body was rapidly adapting to the cold and hot environment.

At this moment, Chen Cao felt the changes in his body more clearly.

The golden key is not to improve one of the body's abilities, but to keep the body evolving.

To put it simply, in fact, the role of the golden key is to improve Chen Cao's adaptability.

In different environments, Chen Cao can adapt to the environment more quickly.

Originally, it takes thousands of years, or even tens of thousands of years, for a species to adapt to a new environment.

But the Golden Key shortens this evolutionary process.

Not only the changes brought about by his body, but also the changes in his magic power.

Adaptation is not immunity, so the damage remains.

However, Chen Cao's resilience has also improved significantly.

Chen Cao's speed is also getting faster and faster.

After a preliminary estimate, Chen Cao felt that his speed might have reached 200 kilometers per hour.

"Chen Cao, you can come out. ”

Chen Cao ran out of the Xuan Ice Realm and the Heavenly Fire Realm.

The old turtle stared at Chen Cao, and he found that Chen Cao had changed a little.

With his eyesight, of course, he could see the changes in Chen Cao.

This made him a little strange, Chen Cao's transformation had not yet been completed, but he had changed so much.

"You can shrink the Xuan Ice Realm and the Heavenly Fire Realm, and now this scale has little effect on you. ”

"Is it better to shrink down?"

"The closer you get to the center, the greater the temperature difference. The old turtle said.

Under the control of the old turtle, the area of the Heavenly Fire Domain and the Xuanbing Domain has shrunk by a large circle.

When Chen Cao went in again, it felt like he had returned to the beginning.

But at this time, Chen Cao was already confident.

......

Chen Cao stayed in Hetu for a long time, and Chen Cao didn't know how long it had been in it.

However, after coming out, Chen Cao found that only five hours had passed outside.

Chen Cao now feels a little uncomfortable with the gentleness outside.

At this time, Fali found that Chen Cao had returned.

She thought that Chen Cao had gone out, but Chen Cao didn't seem to drive out.

"Chen, you seem to have changed a little. ”

Chen Cao touched his face: "Change?

"I don't know, it's just a little weird. ”

"Isn't it more handsome?"

Fali patted Chen Cao's chest: "Where did you go just now?"

"I went to exercise. ”

"Did you run out into the wild?"

"Hmm. ”

"By the way, one of my students, Evelet, you should remember, she has a game next month, in Montreal, Canada, and she invited us to watch her game together, will you go?"

"Yes. Farrie nodded: "By the way, Steven called just now and said that he asked you to call him when you come back." ”

"Good. ”

Chen Cao picked up the phone and dialed Steven's number.

"Hey, Steven, did you just call me?"

"Chen, come here, there is something I need to discuss with you. ”

Chen Cao's heart moved, did Steven and Lasfar plan to carry out that plan?

"Farry, I'll go to Steven's side later. ”

"Good. ”

......

When Chen Cao arrived at Steven's house, Rasfar was also there.

Neither of them drank alcohol this time.

"Chen, remember what we told you last time, right?"

"Are you really going to do that?"

"Well, anyway, even if it comes to light in the end, we say it's a movie shoot, and it doesn't matter to me. ”

"So how do you do it?" Chen Cao asked.

"You act as my personal bodyguard for two days. Steven said, "This is your character." ”

"And then?"

"And then you're obsessed with short videos, and you're going to put them on social media, and you're usually going to take a picture of me with your phone, so you can explain what's going on and why there's a video. ”

Chen Cao nodded, and Steven and Rasfar began to discuss various details with Chen Cao.

"I don't need to show my face, do I?"

"Well, no, you usually shoot me, for example, when I'm at work, or when I'm resting, you can shoot a video and put it on the Internet. ”

"I opened a Facebook account for you, this is the account password, you remember it. Rasfar said.

Chen Cao boarded this familiar account, and his username was 'the personal bodyguard of the great director'.
