two days.

This has reached the limit of time.

Even Yu Xin only spent ten hours in it back then, which was already her limit, and even so, her world power was once cultivated to the seventh level.

So what about this summer?

tread! !

Summer feet out of the canyon.

"How do you feel?" Yu Xin asked.

"Very good, I really didn't expect that there is such a magical place in this world." Xia Xia said with emotion, he felt that this place was a heaven-defying existence. If this place could be opened to the outside world, then there would be countless experts in the Middle and Three Realms. But he also felt it inside.

It is absolutely impossible to open to the outside world.

Because the cultivation environment inside is limited, if one person uses it for cultivation, then he will be very rich, and he can even continuously improve himself. If there are two people, then the person with low realm power is fine, if it is two SS-level mercenaries. , then it's definitely not enough here.

"Well, part of it is natural, and the other part needs a lot of resources to cultivate." Yu Xin nodded.

"Thank you so much this time." Xia Xia really thanked Yu Xin very much.

"How much?" Yu Xin asked.

"The eighth peak." Xia Xia said lightly.

"What?" Yu Xin's face was full of disbelief. She never expected that Xia Xia would actually be able to break through to the top of the eighth level, which was too terrifying.

If Xia Xia breaks through Jiuding now, then he is almost equal to the strength of an SS-level mercenary.

That's not even his own abilities.

"It's so powerful here. I never thought that the power of the world could break through like this." Xia Xia shook his head. All this was a bit exaggerated to him. You must know that the power of the world is one point at a time. He practiced it in a real way, although this time he also practiced it himself.

But this time the improvement is many times faster than before.

In two days, the power of the world broke through from the seventh level to the peak of the eighth level.

"It's important to be special here, but your own aptitude is also very terrifying. I've been in there a few times, and the most I stayed there for ten hours, that's my limit, but you stayed in it for two hours. God, this in itself is not something that everyone can do." Yu Xin praised.

"Thank you for the compliment." Xia Xia scratched his head awkwardly.

"Let's go, this is not the end, there is a place in front of me that I haven't been in before, let's go and have a look." After Yu Xin finished speaking, she walked straight forward, obviously she was changing direction to help Xia Xia, because The places she brings summer are all places where she can increase her strength.

She thinks that she can't save Xia Xia, and she can't fight against the enemy with Xia Xia, so she can only use her own way to help Xia Xia.

Xia Xia also followed Yu Xin to the inside.

The style inside has changed a lot.

When I was outside just now, everything was so beautiful, but when I got inside, everything changed.

In it, the left side in summer is bare, there are no plants, and there is no upgrade, but the right side in summer is full of life.

"How can there be such a big gap here." Xia Xia frowned. At this time, the distance between the two sides was less than ten meters, but the gap was so large.

"This place is called Sun Moon Tonghui. As for why it became like this, I don't know. I just saw the name here on the stone tablet, but at the time I felt that the power inside seemed very terrifying, so I didn't go in." Yu Xin explained that even she didn't know the true meaning of the sun and the moon.

And he never entered it.

"Sun and Moon Tonghui, a very interesting name." Xia Xia said with emotion.

Now that the days before the Heroes Conference starts are getting shorter and shorter, he is trying to improve his strength as much as possible, because the more strength he has, the more chance he has to save his life.

Boom! !

At this moment, there was a sudden sound of shaking from the ground.

"No, let's go!!" Yu Xin said hurriedly.

Then Xia Xia and Yu Xin hurriedly turned around and ran away. Xia Xia didn't ask much. From Yu Xin's nervous appearance, he guessed that it must be Emperor Yu who came here, that's why Yu Xin was so nervous.

Swish! !

A golden light flashed.

Xia Xia's right hand grabbed Yu Xin's waist and ran directly outside.

His speed is faster than Yu Xin, so he can be faster with Yu Xin.

"Yeah!!" Yu Xin's face suddenly turned red.

boom! !

There was another shock, as if a huge city gate opened and closed. Xia Xia knew that it must be Emperor Yu.

Because only Emperor Yu was qualified to enter here.

quick! !

Summer is very fast.

Even with Yu Xin, his speed was much faster than Yu Xin's own run before.

Emperor Yu at this time.

"Why are the organs inside moving? Could it be that someone broke in?" Emperor Yu frowned. This place is very important to him. It can even be said to be the biggest secret of Jiudingmen. Even he can't help it. Don't dare to let anything go wrong here.

In the previous period of King Yu, as long as they were super geniuses, they were eligible to enter here. Later, when Emperor Yu came to power, he changed this rule.

Except for the emperor of Jiudingmen, no one else is allowed to enter.

Because there are too many secrets hidden in it, it can even be said that all the secrets of the entire Jiudingmen are contained in it.

If anything goes wrong, Jiudingmen may face a huge disaster.

"Don't make any mistakes." Emperor Yu quickened his pace.

He has already asked the guards outside just now, and no one came in here, nor did he find anyone approaching here~lightnovelpub.net~ Normally, there is a formation shrouded here, and others can't break in if they want to break in, but He was still unsure, that's why he came here specially. If he finds someone here at this time, he will definitely kill the other party at all costs.

"No, I can't go here anymore, I have to go out, my father came over from the front." Yu Xin said hurriedly, she was calculating the time just now, and she found that if she continued to walk, she would definitely meet Emperor Yu. Once they meet Emperor Yu, Xia Xia will surely die.

Although Jiudingmen wants to cooperate with Xia Xia, this is the biggest secret of Jiudingmen, and her father will never allow any mistakes.

Summer's eyes looked around.

There is no other way.

"No, I can even sense that the airflow ahead is moving." Yu Xin said anxiously.

There is no other way, and if you encounter it head-on, it is a dead end.
