"Is it life-threatening to go more than 30 meters?"

Qin Feng said secretly in his heart.

And when he said to himself in his heart, he realized that his body, which was slightly heavier than before, and there was a little emotion in his heart.

Unexpectedly, in this world, the rune array master still has the means to manipulate gravity.

Although he sighed in his heart, he did not say it.

"Hint, this is not the handiwork of the Fu Array Master. ”

At this time, the system interjected another sentence.

Qin Feng listened to the voice of the system, and suddenly wondered in his heart, if this was not the handwriting of the Fu Array Master, then whose handiwork was it?

Moreover, the various mysterious textures at Qin Feng's feet were densely packed, and they looked very unfathomable.

"Whatever. ”

After saying this in his heart, Qin Feng took a step forward.

He had barely walked far when the door to the entrance behind him closed on its own.

When the sound of the door closing penetrated Qin Feng's ears, the light source that was originally coming from behind him was completely cut off, and his eyes were suddenly dark.

However, after a few seconds of relaxation, he gradually adapted to the slightly dim light in the heavy building.

Following the aisle, he came to the front of the second gate, where the depth of ten meters was marked.

Qin Feng raised his hand to push the door, but the door that should have been easy was like weighing ten thousand catties at the moment, and Qin Feng also took a lot of effort to push it open, and then walked over.

Qin Feng, who entered the second gate, seemed to have consumed too much energy for a while, and he only felt that the gravitational force here was much greater than that outside.

Not only that, Qin Feng also found that the more he walked inward, the thinner the aura of heaven and earth around his body became.

Although it is not particularly obvious, the amount of heaven and earth aura is indeed decreasing.

However, it is precisely because the gravitational force is gradually strengthening and the aura of heaven and earth is gradually thinning, even if Qin Feng walks in it, it is a tempering of the body that he can't get on weekdays.

And if you practice here for an hour, the effect must be far greater than practicing outside for several days.

"Yu Haoyu really didn't lie to me, this is really a good place. Qin Feng secretly said in his heart, "But those two old gentlemen only gave me three hours, so I should hurry up." ”

With that in mind, he walked as fast as he could.

After another ten meters, he came to the front of the next door.

This door is marked twenty meters.

When he stretched out his hands and pressed them against the door, he began to exert his strength, but it was as if he were pushing a mountain, and it took almost a lot of effort to make the door move a little.

The mind moves, and the spiritual power in the body flows with it.

Immediately, the door slowly opened, and Qin Feng reluctantly walked behind the third door.

And standing behind the third gate, he looked at the tenth gate ten meters ago, but his heart was in trouble.

Not to mention that it is a distance of thirty meters, according to the system prompt, Qin Feng's life will be in danger after passing that door.

After these twenty meters alone, every step he took was a huge test, and the gravitational force exerted on his body increased exponentially, which also made it difficult for him to represent the fourth gate at a depth of thirty meters.

He walked forward, and when he finally reached the middle, he stopped.

Keep moving forward, let alone exert force, even simple movements are difficult for him to complete.

After turning around, he opened the door on the left-hand side, this door would open by itself as long as he knocked on the lock, and when Qin Feng walked into this door, he entered a square martial arts room with a length and width of eight meters.

It seems that a special material is used here, and the gravitational force is relatively evenly distributed throughout the martial arts room.

In this third floor, there are more than a dozen such martial arts rooms, which can be walked from the entrance to other martial arts rooms.

After closing the door, Qin Feng stood quietly, adjusting his luck.

After adjusting his own aura to the slightly thin heaven and earth aura around him, Qin Feng's hands gradually formed a spiritual power.

Being here, whether you want to use your strength or spiritual power, it is dozens of times more difficult than in the outside world.

When the breath was adjusted and the spiritual power was raised, his heart began to settle down.

Beware of the water that stops the water, as if everything around him has nothing to do with him.

At this time, only the first part of the fragment of "Open Heaven" was left in his mind, and the spiritual power and strength in his body were gradually on the right track with Zhou Tian.

The fluctuations of spiritual power that were purified from his body were also constantly strengthened over time.

In the first part of the fragment of "Open Heaven", a total of three forms are recorded, namely 'Ascending Dragon', 'Dragon Claw' and 'Flying Stone'.

What Qin Feng practiced in front of Qiongzhou Wufu and others before was the basic essence of "Open Heaven", but did not involve the complete content of the first three styles.

At this time, an arrogant force was gradually converging in Qin Feng's right fist.

And when his fist strength and spiritual power rose, his sleeves suddenly swelled, and then he was torn apart by a huge brute force.

And on the lower half of his arm, there are a few crimson messy textures faintly appearing, as if they are green tendons burning with flames.

"Ascending Dragon!"

When he meditated and felt that the qi in his body was working properly, he threw a fist in his hand in front of him without reservation.

At this moment, the huge force blasted out with his arm that seemed to be stretched out in a circle, and it bombarded the barrier of the martial arts room with all his strength.

Rumble!

At the moment when the tip of his fist smashed against the wall, a faint fire lotus seemed to bloom on the wall, and the sudden rise in ultra-high temperature actually left a faint trace on this wall.

At the same time, outside the heavy building.

Although the huge roar did not come out, it seemed that it was precisely because of that punch that it also made the trees in the same direction tremble for it.

Looking at the leaves rubbing overhead, the two old men looked at each other in surprise.

"It's not my delusion, is it, uncle?"

The sixty-year-old man asked.

The eighty-year-old man squinted his eyes and said, "This son is terrible, and his future achievements will definitely not be below you and me." ”

Before he could say a word, the leaves above his head, which had calmed down again, trembled again.

The two old men looked at the leaves and pondered for a long time.

And in their eyes, all that remains is enduring amazement.

......

The next day, the sun rises three poles.

The two old men returned to the gate of the heavy building and looked inside.

"Uncle Shi, you promised him three hours yesterday, but it's almost a day now. The sixty-year-old man said, "I'm afraid it's not right to do this, right?"

"The rules are set by people, I think this son must have the qualifications to enter the inner door, and Huangfu Long Yin can bring him back to the inner courtyard, so he must also take a fancy to him. The eighty-year-old man said, "When I do this, I just borrow flowers to offer Buddha." After all, people are already old, our era has passed, and the next Daqin is the world of these young people. ”

The sixty-year-old man listened quietly, nodded and said no more.

"However, this is the first time that this young man has entered the heavy building, and this stay is only a whole day, if he can bear it, but if he is reckless, will he not be in danger?" said the sixty-year-old man again.

The eighty-year-old man nodded when he heard this.

"What you said also makes sense, but the shock is still there, which means that he hasn't had an accident for the time being, so you can go find him. ”

The eighty-year-old man said.

After hearing this, the sixty-year-old man nodded his head and pushed the door into the heavy building.

But five minutes later, the eighty-year-old man who was waiting outside the door still did not see them come out, and he was a little puzzled in his heart, so he also pushed the door and walked in.

The eighty-year-old man had just entered, and the sixty-year-old man had just finished searching for a circle on the first floor of the heavy building.

"What about people?"

"Not on the first floor. ”

"Did he go to the second floor? He's only fifteen or sixteen?"

"No matter, let's go check it out first. ”

After the two old men talked, they walked through the second door.

And when the two old men searched around the second layer but still couldn't see Qin Feng, they were all quite shocked.

The youngest genius in the history of the Great Qin Martial Mansion was only able to enter the third layer at the age of nineteen.

"This son actually used such a method in the third layer. The sixty-year-old man exclaimed, "It's terrible, it's terrible!"

The eighty-year-old man glanced at him, and then looked at the third gate.

When the two of them were about to walk towards the third gate, the third door opened on its own.

And it was Qin Feng who walked out from behind the door.

At this time, Qin Feng's two sleeves were torn, and his clothes were already emitting the stench of sweat deposits.

In the course of this day and night, Qin Feng relied on the Sanpin Blood Spirit Pill to maintain his physical strength and fill his spiritual power, and he also rested three times during this time, and the sweat wet his clothes again and again, which caused the current situation.

At this time, the Blood Spirit Pill ran out, and he was ready to come out.

"Why are the two old gentlemen here?"

Qin Feng opened his mouth and asked, "Are you also here to cultivate?"

The second elder listened to Qin Feng's words, and after glancing at each other, they both smiled.

They didn't explain the reason to Qin Feng, and Qin Feng looked at these two people like this, but he was also full of confusion.

And Qin Feng, who didn't get an answer, also followed the two old men out of the heavy building in desperation.

As soon as he walked out of the heavy building, the burden on his body disappeared in an instant, and Qin Feng felt even more relaxed, as if he could go straight to the sky with a casual jump.

"How could it be morning? Have I been in there all day?"

Qin Feng felt the sunshine from the east, and asked with a puzzled face.

The sixty-year-old man said, "I think if you hadn't run out of blood spirit pills, you might not have counted in your heart until the morning after tomorrow." ”

Listening to the old man's ridicule, Qin Feng scratched his head.

Then, he arched his hand at the two old men.

"Thank you two for letting the kid practice in the heavy building all day. ”

Qin Feng thanked.

"You kid still have a little conscience. The sixty-year-old man said.

And the eighty-year-old man looked at Qin Feng with great interest and asked, "How have you cultivated in this day?"

"There has been a lot of progress, and the effect of this heavy building is far beyond my imagination. ”

Qin Feng said with a little excitement.

Indeed, under such heavy conditions, he has been able to run the first three forms freely, although it is far from reaching the point of perfection, but he can also exert his due power.
