Zhang Heng crawled along the uneven wall to the bottom of the pit, because he needed to keep the weight distributed during the climbing, so the speed was not too fast, but the distance of thirty meters was not very long, he still quickly came to the bottom of the pit, first looked around quickly, confirmed that there was no danger, and then shook the flashlight upward.

This was the signal agreed upon by Zhang Heng and Ma Lu, who knew that he had landed safely after seeing the bright light of the flashlight, and then also threw down his travel bag.

Zhang Heng heard the sound of falling above his head, let go of half of his body, and waited until there was a muffled sound and his travel bag fell at his feet.

Zhang Heng lifted the travel bag, patted the dust on it, and then began to seriously look at the environment he was in.

In front of him was an underground pit with a diameter of about sixty meters, and there was no other entrance and exit except for the passage he came down to, but there was a waterhole in the middle, but the strange thing was that there was no sound of water around, and the whole waterhole was unusually quiet, and there was not even a ripple on the water surface.

Zhang Heng shone it downward with a flashlight, and as a result, he could only faintly see the outline of a huge black shadow.

Because it was too far apart, and the light was not clear, Zhang Heng could also see what that thing was, so he took out the [filter lens] later, but this time the [filter lens] that had been tried and tested before also failed, and it did not allow Zhang Heng to see the true face of the thing below.

However, for the sake of prudence, Zhang Heng still made pre-war preparations in advance.

After the Yonaguni incident, he accidentally gained the ability to breathe underwater and control the flow of water, and now he can stay underwater for long periods of time without any oxygen equipment, and controlling the flow of water allows him to move more quickly, or use the current to disrupt the enemy's movements.

Even the best divers in the world are not as easy as he is now, but Zhang Heng knows very well that if he is compared with Jörmungad, who has been living at the bottom of the deep sea in mythological records, his underwater ability may not be much cheaper.

Moreover, the main output weapons on his body, whether it is the [Tibetan Sheath], the [Plague Bone Bow], or the [Paris's Arrow], are all equipment that needs to be on land to exert the greatest effect, so Zhang Heng still prefers to put the main battlefield on the ground.

So the first thing Zhang Heng had to do was to lure Yermungad out of this waterhole.

Anyway, there was no one else here, so Zhang Heng simply took off all his clothes neatly, and put them in a corner of the pit together with the props in the travel bag, these clothes were not professional diving suits, and they could not maintain his body temperature after entering the water, and the loose clothes would increase his resistance in the water and slow down his movement speed in the water.

Even if the amplitude was not large, but considering the opponent he faced this time, any slight difference could affect his life and death, and in the end, Zhang Heng only chose to bring a [Tibetan Sheath] to defend himself.

Anyway, if nothing else, he will soon come out of this waterhole, and the [Plague Bone Bow] and [Paris's Arrow] are hidden by him behind a stone that is closest to the waterhole, so that he can take them out as soon as he lands.

After doing all this, Zhang Heng returned to the waterhole, and he first tested the water temperature with one foot. found that the water in the pool was not as cold as he imagined, and there was no discomfort after waiting for a while, so Zhang Heng completely submerged his body in the water.

He tied the [Tibetan sheath] around his waist, and controlled the water flow to sink to the black shadow below, Zhang Heng didn't know if it was his own illusion, after jumping into the pool, he didn't have any nervousness before the big battle, on the contrary, when the water flow around him surrounded him, he had a faint sense of intimacy, Zhang Heng could also feel the small changes in his body, since he came back from Yonaguni Island, he has become more and more fond of water.

This reminded him of the huge astrolabe-like dome in the undersea ruin palace on Yonaguni Island before, those half-human, half-fish frogs wanted to use him for some ritual at that time, but he was interrupted and escaped halfway, but Zhang Heng knew that something had already begun.

In fact, after coming back, Zhang Heng dreamed of the undersea ruins several times, in which he walked through the undersea passage alone, returned to the undersea palace again, and looked up at its dome.

The stars were constantly turning, as if in response to some kind of longing in his heart.

…………

Zhang Heng sorted out his thoughts and brought himself back to his senses from the previous memories, he had already dived about ten meters, but there was still some distance from the black shadow in it, but the latter did not react at this time, as if he was completely unaware that his home had ushered in an uninvited guest.

So Zhang Heng also deliberately filled the speed of diving, trying not to attract the attention of the other party in his movements, but soon he found that he was completely superfluous.

As the depth continued to decrease, Zhang Heng was finally able to gradually see the appearance of the thing at the bottom of the pool.

It was a huge serpent's head, almost as large as the waterhole, with a pair of cunning and evil eyes, sharp teeth, and reticulated gray scales, and its mouth wide open, as if it were about to rise from the bottom of the pool and swallow its prey in one gulp.

Zhang Heng was also taken aback when he saw it for the first time, thinking that Yermungader was waiting here for him to throw himself into the net, and he was almost about to control the current and send himself ashore, but after he rose five meters, he found that the snake head below did not have any reaction, and still maintained the appearance of being eager to try and ready to pounce, so Zhang Heng stopped again.

After hesitating for a moment, Zhang Heng took out the [Tibetan Sheath] and tried to sink slowly again, this time he finally saw the true face of the snake's head.

- It wasn't a living thing at all, it was a stone statue!

It's just that because the carving is too real, it has a lifelike feeling, especially its two red eyes, which are actually directly set with rubies, if you don't see it with your own eyes, it's hard to believe that there is such a big ruby in the world, the diameter is probably more than two meters, and there is an indescribable evil luster underwater.

Zhang Heng slightly sped up his dive, allowing himself to get closer to the stone carved snake head.

Only by standing in front of it can you appreciate how good its carving is, no less than the masterpiece of any artist in the world, but when Zhang Heng saw that his eyes were removed from the snake's head and looked around the bottom of the pool, he could not see the trace of the main owner.

If nothing else, Jörmungård was back in the waterhole after dragging the sperm whale to the station, and unless it had evaporated from the world, it should still be here.
