One step, Zhang Yu's vision suddenly became broader.

In front of him, there was an extremely empty hall, and in the center of the hall, there was a huge crystal sarcophagus one foot square.

Zhang Yu's eyes locked on the crystal sarcophagus, as if he wanted to see what was inside, but he could only see a hazy patch. As for what was inside the crystal coffin, he still didn't know anything.

The more this happened, the more curious Zhang Yu became, and he couldn't hold back for a while, Zhang Yu took another step.

"Poof!"

A dull sound sounded, and Zhang Yu fell to his knees.

"Daddy!"

Zhang Yu couldn't help but cry out loudly, the desolation in that voice seemed to make people's hearts and intestines broken, and he couldn't help but feel pity.

The gravity inside and outside this hall has changed dramatically.

If the gravity in the passage is thirty or forty times that of the outside world, the inside of this hall is seventy or eighty times that of the outside gravity, and the two are only separated by a line, but the two different gravity forces are clearly distributed on both sides.

Little by little, the fractured left leg was withdrawn from the main hall, Zhang Yu sat cross-legged and began to repair the obviously deformed left leg.

It is said that the ten fingers are connected to the heart, but the ten fingers are still connected to the legs, and the pain brought to Zhang Yu by the comminuted fracture of the calf is a lot, and the sourness is almost deep into the bone marrow.

If he had been mentally prepared in advance, it was estimated that such a tragedy could have been avoided, but who would have thought that the construction of this catacomb would be so insidious, with two different gravity forces set up inside and outside this hall, and anyone could be injured if they were caught off guard.

Zhang Yu is still lucky, if it is the spiritual cultivation that only focuses on comprehending the Heavenly Dao in today's cultivation system, I am afraid that it will be even more miserable, and it is even a luxury to get out of this underground palace alive.

However, under normal circumstances, no one would drill into this hundreds of zhang deep for no reason, and Zhang Yu was an exception.

Mobilizing the blood qi in the flesh to continuously nourish the shattered patella and a small leg bone, Zhang Yu could feel that they were recovering rapidly, and at this time, the power of the ancient bloodline in the depths of Zhang Yu's veins also began to operate spontaneously, making his injury recovery invisibly much faster.

After more than two hours again, Zhang Yu's injuries were finally healed, and the blood qi consumed was also replenished under the effect of the elixir. In this strange catacomb, Zhang Yu must keep himself at the top of his game at all times.

Although his behavior may be a bit excessive.

Staring at the crystal coffin in the center of the main hall, Zhang Yu didn't dare to take a step easily for a long time.

More than 30 times the gravity is good to say, but 70 times the gravity, even Zhang Yu does not dare to try it easily, he is afraid that if his body can't bear it, it will be the end of death.

Trying to adjust the operation of the blood and qi around him, Zhang Yu strives to adjust himself to the most perfect state.

After walking back and forth in place several times and fully adapting to the thirty times gravity in this passage, Zhang Yu took a deep breath and began to truly challenge the seventy times gravity limit!

"Bang!"

As soon as he stepped out, Zhang Yu felt that his steps were as heavy as a mountain, and even the ground shook violently. At this time, he felt like a giant elephant, walking on the ice that had just condensed, walking on thin ice with every step.

"Whew!"

After taking a heavy breath, Zhang Yu stood firmly in place.

Zhang Yu did not rush forward again, but constantly adjusted the various functions of his body, and tried to make all his cells fully adapt to this gravity as soon as possible.

Under the terrifying gravity of seventy times, Zhang Yu felt that his cells were no longer as active as before, and he was groggy, like an old man who was about to die.

Just imagine, if a person's weight is only 100 catties, but under 10 times the gravity, it will reach a terrible 1,000 catties, and 70 times the gravity, that is the terrifying 7,000 catties!

In terms of weight alone, it is completely comparable to an adult monarch-level demon beast.

However, the weight gain caused by the increase in gravity is very different from the normal weight growth on its own, and the growth process of the monster, whether it is bones, muscles, or meridians, there is a process of growing and adapting together, thousands of catties, tens of thousands of catties of weight, is borne by a huge whole.

Zhang Yu here?

The body has not undergone any adaptation and strengthening process, and a skeleton directly has to bear seven thousand catties of terrifying gravity, which is simply difficult for a strong man.

Fortunately, he is a physical cultivator! When the physical body is refined, even the internal organs and bones are tempered a lot stronger, otherwise, he really can't hold on.

At this time, Zhang Yu didn't have any experience to rely on, and he also lost Mochen, the biggest reliance, and if he wanted to get through the difficulties, everything had to rely on his own efforts.

Under extreme gravity, his heartbeat increased suddenly, but the blood flow was extremely slow, which caused Zhang Yu's chest to be like pressing a boulder, and every breath was extremely difficult.

The formless and massless gravity, like an invisible hand, squeezed out the air in his chest little by little.

Looking closely, Zhang Yu's face gradually turned iron-blue, and even a little pale, which was a sign of a serious lack of blood supply.

Taking another step, Zhang Yu's body stumbled, and he almost fell to the ground, and after swaying left and right a few times, he finally stood still.

But at this time, his consciousness became a little blurry.

The ancient bloodline in Zhang Yu's body ran wildly, and suddenly wisps of flames drilled out of the pores of his body, and the scorching flames completely enveloped him, and the space around Zhang Yu's body was slightly distorted.

The temperature inside the hall soared rapidly, and if it weren't for the gravity-reinforced rocks that had become as dense and hard as steel, the ground might have melted into flames.

Slowly, the flames condensed by the power of Zhang Yu's bloodline seemed to no longer be willing to be confined to his body, and began to spread outward little by little.

After a short while, the entire hall seemed to turn into a sea of flames.

Under the wrapping of the flames, Zhang Yu felt that the pressure on his body had become a lot easier, and the original feeling of suffocation had gradually disappeared, although his body still weighed more than 10,000 pounds, but he was finally able to persevere.

Glancing at the crystal coffin wrapped in flames, Zhang Yu's eyes also suddenly condensed, the power of the flame that can incinerate all things even softened the ground, but the crystal coffin showed no signs of damage at all, and the most shocking thing for him was that the crystal coffin actually emitted a stream of cold power, and when those flames encountered these cold powers, they would run away like a mouse seeing a cat.

But the cold power seemed to have a spiritual intelligence, and it suddenly rushed out to catch up with the flames that wanted to retreat, and swallowed it up at once.

Seeing this, Zhang Yu hurriedly urged the power of the blood veins to gather the flames that spread out.

These flames are derived from the power of his bloodline, and every loss is a great loss for him, and Zhang Yu is very distressed.

When Zhang Yu gathered all the flames back into his body, those cold powers seemed to be somewhat restricted, wandering around the crystal coffin.

The temperature in the main hall also dropped rapidly, and in the blink of an eye, except for Zhang Yu's surroundings, the rest of the place was as cold as a thousand-year-old ice cave.

As far as the eye can see, one of the main halls is steep and cold, and the other is flowing gold and stone, and the two completely opposite scenes appear in the same world, which is amazing!

And the temperature in the main hall is still dropping, even if Zhang Yu urges the power of the flames around him, he can't change this trend.

However, Zhang Yu did not regret using the power of the bloodline to give birth to flames to protect himself, if it were not for the support of these bloodline flames, he would have been crushed by the terrifying gravity, and wanting to stick to it is tantamount to a fool's dream!

"Can't wait any longer. Zhang Yu glanced at the crystal coffin, and under great pressure, he walked towards the crystal coffin in the center.

Zhang Yu had an intuition that only by stepping into the scope of the crystal coffin could he stop this cold power.

"Boom!"

"Boom!"

With every step, there was a dull sound in the hall, and in the process of marching towards the crystal coffin, Zhang Yu had to constantly use the power of flames to counteract the power of the extreme cold.

If at this time, Zhang Yu suddenly withdrew the power of the flames, he might even be frozen to death!

Advancing step by step with trepidation, the snail-like speed seems so ridiculous, but it is a matter of life and death, Zhang Yu has no smile.

In his eyes, the crystal coffin became the only insistence in Zhang Yu's heart.

The power of the flames was exhausted little by little, and Zhang Yu's body gradually weakened. Seeing that there was still the last ten meters left, Zhang Yu's body seemed to be disobedient, the soles of his feet were like being filled with lead, and every step was so heavy that in the end, he couldn't even lift his knees!

There seemed to be a magic sound in his mind, constantly making Zhang Yu stop, so that he could no longer bear such a terrible gravity and rest well.

The upper and lower eyelids kept trembling, and it seemed that they would close at any time, Zhang Yu gritted his teeth and stabbed his thigh fiercely with the thunder sword, and the pain made him clear again.

He knew that he couldn't sleep, otherwise even without the oppression of gravity, the extreme cold would keep him asleep forever.

It is more appropriate to grit your teeth and take steps a little bit, or move your body a little bit. He had to use all his strength every time to move his body forward by two or three centimeters.

In this way, with the kung fu of terrazzo wearing, he had already stepped into the cold range of the crystal coffin, and stretched out his hand to press forward, but he was still the last finger away!

But in Zhang Yu's opinion, the distance of this finger has a sense of being close to the end of the world!

Most of all, in order to counteract the ubiquitous cold, his flame power was on the verge of collapse!

"Roar!"

His eyes were scattered, and Zhang Yu, who was confused, let out a roar like a beast from his mouth, and rushed forward with the last bit of strength.

Three centimeters, two centimeters......

"Smack!"

A soft sound came, and the extremely cold power that kept coming out around the crystal coffin quickly disappeared, and before the will fell into darkness, Zhang Yu vaguely saw a stunning face lying peacefully in the crystal coffin!
