My system can be changed

Since the second half of the back mountain was extremely steep, and there were even dozens of kilometers without roads, the speed of the two of them was significantly reduced, and they only walked about ten kilometers from morning to noon.

"Brother Yu, there are still fifty kilometers left, and we will reach the top of the mountain."

Cang Tong looked up, carefully calculated the degree of distortion of the mountain road, and smacked his lips.

Because the height of the back mountain is more than 1000 meters, and there are many monsters that have absorbed the spiritual energy, the mountain road is also very twisted.

Lin Haoyu sighed, with a loveless expression:

"There are still [-] kilometers left. Labor and management have finished their fucking journey in the past two days!"

The total length of the mountain road is [-] to [-] kilometers. If you want to finish it in two days, you have to walk [-] kilometers a day, which is equivalent to [-] hours of walking time per day.
And that's not counting, there will also be various monster attacks, and if you are not careful, you will die.

Just after complaining a few words, I heard a strange noise behind me.

"Ok?"

Lin Haoyu immediately looked around in surprise, only to see Erha hiding in the grass and staring blankly at them.

Silently walked over to have a look, Lin Haoyu's eyes were full of hehe:
"Fuck, you two, I didn't expect us to meet again, it's so fate."

That's right, these two Erhas happened to be the two that Lin Haoyu saw last night, and it seems that these two Erhas are quite unfriendly to Lin Haoyu.

Thinking about how his family would bite him when he was upset, Lin Haoyu decided not to provoke these two haha, his life is the most important thing.

Continuing to move forward, in less than a few hours, Lin Haoyu and Cang Dou finally arrived at a place less than five kilometers away from the top of the mountain.

"It's still five kilometers away, let's go all out!"

Lin Haoyu gritted his teeth, rubbed his sore legs, and continued to move forward.

Cang Tong on the side is also not having a good time, because he has been walking in front to open the way, so his arms are full of scars.

Cang Tong frowned and looked forward:
"Wipe, sure enough"

Cang Tong was a little vigilant in his heart. The place five kilometers before the top of the back mountain was said to be the place where Xiazhu-level monsters lived, and their strength could be compared to Xiazhu.

Slightly squinting his eyes, he could only see a thick layer of mist shrouded in it, and the surrounding air suddenly became colder.

"Ice Behemoth, Master Realm, Ice Manipulation Technique, Water Attribute."

Cang Tong stretched his muscles silently, looked around with a solemn face, for fear that he would be eaten by this monster if he didn't pay attention.

"The fog around here should be created by this monster to protect itself. Brother Yu, we have to be careful."

As he spoke, Cang Tong took a deep breath, carefully walked into the mist and explored for a long time, and then he walked out of the mist, panting heavily, and solemnly said:

"It shouldn't be poisonous, but Brother Yu, the two of us must find a rope to tie together, or we will get lost if we don't pay attention."

Before the words fell, Lin Haoyu glanced at Cang Tong in surprise, and then walked into the mist.

Seeing this, Cang Tong was taken aback for a moment, then let out a loud roar:

"Brother Yu! Damn! There's fog everywhere—"

Lin Haoyu blinked his eyes in bewilderment, licked his lips, and raised his hand with a wave, the whole mist suddenly dissipated, and the strong wind rushed straight into the sky.

"So what, is this okay?"

The fog gradually dissipated, revealing Lin Haoyu's figure.

Cang Tong's pupils suddenly dilated, his face was full of incredulity, and his mouth grew a little outrageously. He didn't react for a long time:

"Brother Yuyu, you still have such a fucking operation?!"

Suddenly, Cang Tong felt that his IQ was insulted——

All the books about Xiashan in the entire Xiashan City mentioned this mist and the giant beast in the mist.

However, most of the solutions are about how to protect themselves and judge the direction after entering the fog, but no one has ever thought of dispelling the fog.

Cang Tong swallowed his saliva, looked at the clean front, and couldn't help punching again.

"Whoa!"

The wind and waves were raging, the white mist gradually dissipated, and the visibility of the road ahead reached about 1000 meters, which was enough for two people to walk for a while.

"Well, let's keep going?"

Cang Tong smirked a few times in embarrassment to ease the previous embarrassment, said.

Lin Haoyu nodded, exerting strength on his feet, and went out tens of meters in one jump:

"Arrive at the destination as soon as possible, it should be less than twenty hours now?"

What Cang Dou said before was to reach the top of the mountain within two days, that is, within 24 hours and within 48 hours.

Cang Tong was stunned, took out a Xiashan special clock from his bosom, nodded and said:
"Yes, only eighteen hours have passed since entering the mountain."

That is a full day and a half, and the two are about to reach the top of the mountain.

The two continued to move forward in the fog, punching the gradually gathering fog from time to time to ensure that the surrounding air would not be cut off.

After counting 10 minutes.

"boom!"

Lin Haoyu swung his fist forward vigorously, and the fog instantly dissipated into a big hole about 2000 meters long. The surrounding fog gradually dissipated to the sides, revealing the sunlight above his head.

But in the next moment, the mist began to gather towards the interior again.

Lin Haoyu frowned, sighed and said:
"It can't go on like this, we must leave this ghost place as soon as possible."

Who the hell knows if this mist is poisonous?
If it wasn't for the fact that the height of the fog wasn't too high, and the gathering speed wasn't fast, they probably wouldn't be able to enter here at all.

And once the inner strength is exhausted, the two of them will be suffocated to death in this magical fog formation, and they will never come out forever—now Lin Haoyu finally understands the Xia Lord who got lost here back then.

Cang Tong gritted his teeth, looked towards a cave beside him, clicked his tongue and said:
"Well, Brother Yu, otherwise we might as well go to the cave over there to rest for a while. The next journey will probably use a lot of internal energy."

The biggest advantage of ancient warriors is that they can quickly replenish energy with food.

As long as there is food, the two of them have infinite internal strength.

Lin Haoyu narrowed his eyes slightly, and before he could see two sentences, the fog almost gathered, and he couldn't help sighing:
"Forget it, let's take a rest first, and the gathering speed of this white mist seems to be getting faster and faster."

After making up their minds, the two strode towards the cave, and quickly blocked the entrance of the cave with a large amount of soil before the white mist poured in.

"Are you sure dirt will work?"

Lin Haoyu looked indifferently at Cangtong digging up a large amount of soil from the entrance of the cave with his bare hands, blocking the vents, and couldn't help laughing.

Once there is no oxygen, everyone will be finished.

Lin Haoyu shook his head and sighed:
"I don't know what the hell this cave leads to."

Before finally reaching the top of the back mountain, you can't get lost in this ghost cave, right?
Because the entrance of the cave was blocked, the two had to use lighters to make torches for lighting, so they could barely walk in the cave.

Lin Haoyu took Cang Tong and strode towards the depths of the bottomless cave.

"hiss"

Suddenly, Cang Tong took a sharp breath, and looked forward with horror on his face:

"Fuck, sure enough, sure enough it's here!"

Hit it, hit it.
The rapid heartbeat made Cang Tong even more flustered, even Lin Haoyu who was at the side was startled by Cang Tong's sudden madness, turned around and glanced vigilantly, and asked seriously:

"what happened?"

"Ice Beast, you can't go wrong."

Cang Tong had some fear in his eyes, but in the next second he clenched his fists fiercely, gritted his teeth and said indifferently:
"Fuck! It doesn't matter whether he is a master or not, as long as we don't leave our backs to this guy, we will be fine."

Well, this sentence was seen by Cang Tong in a strategy book about Houshan, although even Cang Tong himself did not believe it.
But now, they have no way out.

Lin Haoyu made a gesture, his eyes full of doubts:

"Ice behemoth? Grandmaster level?"

Ok?
Why do you feel that the terms Cang Tong mentioned today are all things he can't understand?

Lin Haoyu frowned. After thinking for a long time, he couldn't think of any giant beasts in the back mountain of Xiashan, and he didn't know what giant beasts there would be in this world:
"You mean, what kind of ghostly ice giant beast is there in front of it, and it is also a giant beast with the strength of Lord Xia?"

Cang Tong looked pale, forced himself to remain calm, nodded and said:
"That's right, after the realm of vitality is the realm of Qiankun, and after the realm of Qiankun is the realm of masters."

Lin Haoyu curled his lips, and said indifferently:
"It doesn't matter what the grandmaster Qiankun is, as long as we can leave here alive, one day we will be able to abuse this guy."

Cang Tong was silent for a long time, sighed, and shook his head.

It's not that he didn't dare to fight the ice giant beast, but that he didn't want to fight the ice giant beast——

Except death is death, isn't it full of food?
Cang Tong rolled his eyes, and immediately drew up a plan, swallowed his saliva, and said nervously:
"Brother Yu, why don't we go to the top of the mountain first, and then go to Yecheng on the other side of the mountain?"

"It's already here, it wouldn't be a waste not to fight this thing!"

Lin Haoyu sneered with disdain, moved his whole body, and his inner strength suddenly filled his whole body.

Waving his hand, Lin Haoyu strode forward, looking back and smiling:
"Cang Tong, if I haven't come back in 10 minutes, you can go directly to the top of the mountain and return to the city."

After finishing speaking, the ten-meter-circle field around Lin Haoyu suddenly opened, and a single thought spanned a distance of ten meters.

That's right, due to the extensive use of internal and physical strength before, Lin Haoyu accidentally strengthened the field, making the radius reach a terrifying ten meters.

"This"

Cang Tong was stunned, and shouted in horror and worry:
"Brother Yu! Qianqiu is still waiting for you to go back! You fucking go back!"

Before the shout could be heard, Cang Tong only felt a buzzing in his head, and then completely lost consciousness in the next second, and passed out on the ground.
