As soon as he set foot on the foot of the mountain, Gu Ding noticed the abnormality of the mountain's gravity.

"The initial gravity is about seven times the normal gravity of this world. This strength should be related to the strength of your body." Neptune detected the general situation of the mountain. "Every time you take a step, the gravity will actually increase slightly. Almost every meter above sea level, the gravity will double. Moreover, every ten thousand meters, there will be an obstacle. In addition, you will also encounter some demon beasts along the way. "

"Indeed, with every step, the gravity will increase." Gu Ding also felt the change in gravity here. "However, this is not a big obstacle for most people."

"You're wrong about that. Gravity is a big obstacle for people in this world. Because everyone in this world is a combat cultivator, their body cells are born different from yours. Coupled with acquired training, the density and weight of their body cells are hundreds of times higher than yours. Each of them weighs at least a few hundred times or even a few thousand times more than you do, "Neptune corrected.

"In other words, the gravity they endure from the beginning is hundreds or even thousands of times more than mine!" This news was a little unexpected to Gu Ding.

Climbing all the way up from the foot of the mountain, Gu Ding could feel the gravity increasing with almost every step, but it did not affect his body much. Gu Ding quickly climbed to a height of thousands of meters. As he climbed higher, the seven times gravity that Gu Ding felt quickly increased to more than thousands of times.

"There is a group of first-rank true god-level demon beasts not far ahead. There are a total of eleven of them. The life forms in this mountain are relatively agile because they live in such a strong gravity environment for a long time. Should we go around them? "Neptune suddenly asked.

"No, it's a waste of time to go around them. It's better to get rid of them directly."

Gu Ding did not plan to go around them because the territory of a true god-level demon beast was usually not small. If he wanted to go around them, he would have to walk a long way. Moreover, according to Neptune, the demon beasts here were agile because they had adapted to this kind of living environment. They did not really have an absolute advantage in speed.

After walking for a few kilometers, Gu Ding appeared directly in the territory of the group of demon beasts.

It was a group of black wolf beasts. They were huge, more than ten meters long, and their height was almost the same as Gu Ding's current height. His entire body was wrapped in a layer of black scale armor, and his forehead was covered by a black shield. Other than that, its claws were as sharp as silver daggers, reflecting a cold light.

It was obvious that this was a group of Demonic Beasts with decent defense and attack power.

When they saw Gu Ding appear, eleven pairs of glowing red eyes stared in Gu Ding's direction at the same time.

"Looks like they really want to eat me. They're drooling." Gu Ding also noticed that some of the eleven Monster Beast Sect members were drooling on the ground.

"Based on their reaction, it means that they must have encountered humans in the past and eaten them before, and they found them delicious. Your appearance caused them to miss humans as food, so they couldn't help but salivate. "Neptune began to analyze why these monsters would salivate from a scientific point of view.

"Alright, looks like it's my fault …" Gu Ding was speechless when he heard this analysis.

The two of them communicated telepathically for only a moment, and in that moment, the eleven Demonic Beasts pounced.

Gu Ding stood motionless. His adaptability to the environment here was not as good as these monsters, so he chose to stay still.

When the eleven Demonic Beasts opened their mouths to bite him, Gu Ding finally moved. He pointed a few times in succession, and the finger force directly penetrated the eyes of the eleven Demonic Beasts and shot out from the back of their heads.

The eleven Black Wolf Beasts fell to the ground one after another, no longer breathing.

Gu Ding waved his hand and kept all the Demonic Beasts' carcasses in his bag. Without stopping, he continued to climb forward.

The whole battle took less than ten seconds. If it was a detour, it would have taken more than ten seconds.

Gu Ding continued to climb, and the altitude he was at was constantly increasing. Three thousand meters, four thousand meters …

Along the way, he encountered several groups of Demonic Beasts, but they were all easily dealt with by him.

Just like that, more than ten minutes passed, and Gu Ding reached a height of ten thousand meters.

Looking at the huge waterfall and the nearly vertical cliff in front of him, Gu Ding narrowed his eyes slightly.

"The gravity here has reached more than ten thousand times. The water in this waterfall is not ordinary water, but extremely dense heavy water. The impact of the waterfall will be very terrifying. This waterfall covers almost the entire area of the mountain, and there is only one small path that can only allow one person to pass at a time. However, it is very far from here, hundreds of kilometers away. For safety reasons, I personally suggest taking the detour and taking that small path, "Neptune gave his suggestion.

"Not many people know about that small path, right?" Gu Ding suddenly asked.

"No one should know about it because it is hidden very well inside the waterfall."

"In other words, almost everyone climbs through this waterfall. In that case, there is no need for me to take that small path. Moreover, taking a detour for hundreds of kilometers would waste a lot of time. "Gu Ding still chose to climb.

Gu Ding walked to the bottom of the waterfall. The strong impact of the heavy water almost made him lose his footing. However, it only took him a few seconds to adapt to the intensity of the impact. Once he steadied himself, he began to climb.

The stone that the heavy water had impacted was extremely smooth. Gu Ding could only try to control his strength so that he had enough friction. If he used too little strength, the friction would not be enough, and his hand would slip. On the other hand, if he used too much strength, he would accidentally crush the stone. Under normal circumstances, it would not be difficult to control this kind of strength. However, under the impact of the waterfall, he had to mobilize every muscle in his body to resist the impact, and it was difficult to control the strength in his hand. Moreover, under the crazy impact of the heavy water, there was no way to look up at where the stone was. He could only touch it with his hand, which indirectly increased the difficulty.

Gu Ding could only close his eyes, feel his way all the way, and slowly climb up.

After more than two hours, Gu Ding finally climbed to the top of the waterfall with great difficulty. During this time, he had crushed hundreds of stones, and he had fallen down twice because of the impact of the heavy water.

"I've only climbed twenty thousand meters, and it took me more than two hours. I'm afraid it would be difficult for an average person to complete this in twenty hours." Gu Ding did not expect the difficulty of the preliminary test to be so high.

"The difficulty of the later stages is not as high as this. You're the first to complete the waterfall. The highest person has climbed to more than four thousand meters, and most of the others are more than two thousand meters. It would probably take an average person at least ten hours to complete this stage, "Neptune immediately comforted him.

"Let's continue!" Looking at the river in front of him, Gu Ding knew that what he had to do was continue to go against the flow of the river.

What Gu Ding did not know was that his performance had been seen by the examiner, Bartley.

"Gulot … This guy is quite good. It only took him two hours to complete the most difficult waterfall climb. Among this group of people, I'm guessing that those who did not pass will be because they wasted too much time climbing this waterfall. "Bartley also knew the difficulty of these tests.

Twenty thousand meters, thirty thousand meters, forty thousand meters …

Gu Ding easily passed each stage. Even if he encountered a true god-level monster beast blocking his way, he would solve it quickly, and it did not take him any extra time.

Another three hours passed quickly, and when Gu Ding had climbed to a height of ninety thousand meters, the second waterfall climber completed the climb.

At this time, Gu Ding also entered the final area of ice.

This area was covered with ice and snow, and the biting cold made even Gu Ding's body tremble involuntarily.

"It's so cold …" Gu Ding's voice trembled a little.

"You can't use Divine Fire to warm yourself, or the secret of your God Source will be exposed. You can only use your body to resist it." Neptune stopped Gu Ding's idea of using Divine Fire to warm himself.

"I don't think I can withstand it for long if I resist it." Gu Ding found that the surface of his body had begun to freeze, and it would not be long before he was sealed in ice.

Neptune was silent for a moment before saying, "I found a way to keep warm in the database. It uses the vibration of your muscles to generate heat. This method consumes a lot of energy, but you have a lot of Red Blood Crystals, so this won't be a problem. "

"Muscle vibration? Let me try it. "Gu Ding immediately tried this method when he heard it.

Gu Ding was already able to perfectly control every muscle fiber in his body when he reached the Minute Subtlety Realm in martial arts. It was a simple thing for him to make his muscles tremble.

After just a moment of trying, Gu Ding's muscle fibers began to tremble. The frequency of the trembling also increased from low to high until his body began to generate heat and was able to resist the cold outside before it stopped increasing.

"It really works!" Gu Ding did not expect this method to work.

After swallowing a handful of Red Blood Crystals, Gu Ding controlled the trembling of his muscles as he sped up.

Bartley, who had been watching him, was surprised to see the originally slow Gu Ding suddenly speed up and that the ice and snow covering his body had disappeared.

The intense trembling of his muscles consumed a lot of Gu Ding's energy. Almost every time he walked, he needed to swallow a handful of Red Blood Crystals to replenish his energy.

Bartley saw his behavior and thought it was very strange. "The energy inside the Red Blood Crystals can be absorbed using some special methods, but can it really be digested by eating it like this? Or is there something wrong with this kid's digestive system? "

With the method of obtaining heat, Gu Ding still easily broke through the last hurdle.

About half an hour later, Gu Ding finally reached the top of the mountain. He saw the square that the examiner had mentioned before and quickly moved to stand on the ground in the middle of the square.
