The surroundings were quiet, and the sound of water coming from the depths of the cave could be faintly heard.

The sound of the water is very thick, and it belongs to the river that is calm on the surface but surging in the undercurrent.

He stepped forward with small steps, getting colder and colder, but still within the range of bearing.

Life is cut off in the cavern, and the only enemy in such a freezing place is temperature.

He had to fight against the bitter cold.

The two immortal veins on Wu Heng's back shone out, exuding a trace of white immortal qi to resist the cold wind sweeping from the depths of the cave.

His pace quickens and quickens to speed up his heart beat and generate heat.

It's almost impossible to adapt to the environment here, all you can do is keep exercising.

Later, he began to run wildly in the narrow and long passages, his breathing became rapid, and he used every muscle of his body, which consumed a lot of physical strength, but also stimulated a lot of calories in his body.

After running for about ten minutes, Wu Heng came to the end of the cave and found a pool of white mist.

The Yin River is an underground undercurrent, which can also be called an "undercurrent". Refers to a river below the ground.

"It should be the river that Xing Yu described that contains the true water of Taiyin, right?" Wu Heng glanced at the white mist hazy pool in front of him, and knew that this was a small piece of the underground dark river, and the bottom was huge.

Sure enough, it's cold!

Wu Hengguang glanced at it, and he felt that his teeth were cold.

It's no wonder that even the immortal powerhouses don't dare to break through easily.

"People who have even broken into the black hole of the universe once, are they still afraid of this?" Wu Heng inspired himself in his heart, and then gritted his teeth and was ruthless, and a fierce man plunged into the "pool", splashing a large splash.

"It's unreasonably cold, no matter how hard the water hits, the river should always be frozen. Wu Heng trembled, further proving that the river contained Taiyin true water.

Taiyin True Water never freezes, it has terrifying corrosiveness, sprinkle a drop of Taiyin True Water on an iceberg, and the iceberg will be quickly melted!

"I hope I don't run into those guys. "Wu Heng prayed.

"Boom!"

Suddenly, Wu Heng's whole body erupted with golden divine power, like a sudden lantern flying forward underwater, his arms shook with the strength of tens of millions of catties, stirring up rolling waves behind him, and people sprinted like a weave.

The water of the Yin River was cold into the bone marrow, stinging every inch of Wu Heng's body.

He felt his heart beat slower and slower, numb with cold, his facial muscles stiffened, and his body movements became dull.

"It's even harder than I imagined......" Wu Heng's teeth kept shaking, and his face was covered with frost.

Fortunately, he is a Xuanbing Ancient Divine Body, and in a cold place, he will have a cultivation growth effect, so that he will not be unable to move an inch.

In the current, Wu Heng's feet stepped on the zigzag array, and his hands kept paddling backwards, causing a huge driving force, so the speed in the water was faster than walking on land.

"It's over, my heart has been frozen, and I won't beat anymore......" Wu Heng's figure suddenly paused for a moment.

This is not good news, once the heart stops beating, the oxygen supply will be cut off, and his body will be out of control, how will he get through the water when the time comes?

At the necessary moment, Wu Heng had to use the dragon marrow!

A drop of dragon marrow goes down to the belly, and the heart that has stopped beating gradually wakes up and looks new.

The dragon marrow is the essence of the dragon, which has been improved in all aspects, and some people even say that the dragon marrow can live the flesh and bones of the dead, and it can do anything.

He found many cold-resistant treasures in the heart dragon pattern jade, and found that the soft silver glow emitted by the night silver bead had a great effect on carrying the cold, and he was happy in his heart, and grabbed a night silver bead in one hand, and the function of the body being frozen began to soothe down.

But Wu Heng still felt that it was not enough, and he was still shivering with cold, which was very uncomfortable.

The biggest weapon against cold and fire is naturally fire!

However, there are very few flames that can be burned in the water, and even rarer in rivers that contain the true water of Taiyin.

Wu Heng thought about it, and soon thought of a good thing, his eyebrows lit up, and the Flame Heavenly Book was sacrificed from it!

Immediately, he summoned a large number of purple heavenly fires around him, and the temperature suddenly rose, as if a warm wind was blowing in the cold winter, and he felt like he had come to heaven for a moment.

However, the "warm wind" soon ended, and Wu Heng suddenly fell from heaven to dark hell, and even the purple heavenly fire could not survive for too long in the river containing the true water of Taiyin.

Wu Heng learned his lesson, and summoned the purple heavenly fire for the second time and directly summoned a hundred-meter-high purple flame giant, which instantly became a big furnace for him to bake.

"It turns out that baking a fire in a cold place is such a pleasant thing!" he said as if he had discovered a new world, and his face was full of enjoyment, not bitterness, but real enjoyment. In a harsh environment, people will know how to be simple and happy.

The hundred-meter-tall flame giant heat was still flowing extremely fast, and it was difficult to hold on for even a minute, but it was not a problem, he raised his hand and waved his hand, pointing out hundreds of hundred-meter-high flame giants accompanying him.

These guys were expressionless, standing around Wuheng like bodyguards, making him immediately feel like a supreme treatment.

"It's so warm!" he rubbed his hands, his delicate face was purple and red by the flames, and he began to have a blood color, he should have summoned the Flame Heavenly Book as soon as possible, although the power of the essence consumed was huge, but he had money, 13,000 catties of divine stones were placed, and he could consume them casually!

The most peculiar thing about the divine stone is that it contains a large amount of immortal power, and the spirit stone can't be compared to it at all.

Wu Heng found that the area of this underground dark river is very large, at least 100 miles wide and tens of thousands of miles long, leading directly to the boundary of Tianmen Mountain.

As he approached his destination, he couldn't help but become nervous.

What is the battle situation in Tianmen Mountain at the moment?

Isn't it already a river of blood?

No matter how short the time he has been in it, he is the enshrined sage of Tianmen Mountain, and he has a responsibility.

If you have received favor, you will repay it.

He hoped that Tianmen Mountain would survive this catastrophe!

Under the cold-resistant means such as the Flame Heavenly Book, Dragon Marrow, and Night Silver Bead, as well as the Xuanbing Ancient Divine Body's original great immunity to the cold, Wu Heng successfully broke out of the Yin River and saw the light of day again.

"Boom!"|.

He burst out of the water and quickly dried his wet clothes with a purple fire.

The surroundings are still cold, shrouded in fog, and those fogs are all caused by the cold, and there is no vitality in a radius of hundreds of miles, and there is no strong man of the Giant Clan to guard it.

Wu Heng hurried in a marching formation, and a distance of six hundred zhang was one step, which was equivalent to about four miles in one step.

In fact, he was able to achieve this kind of speed when he was in the Dragon Transformation Realm, but the more he went to the back, the smaller the improvement, and it became extremely difficult to progress a little bit.

But a small increase in speed equals a huge increase.

For example, a young man is 600 zhang in one step, and an old man is 600 zhang in one step.

Then the old man will always have an absolute advantage
