Holden frowned, and immediately became alert. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 Info's call from the depths of the darkness was faint, but he couldn't have misheard, and it was a familiar voice to him.

He knew that Dr. Smith had been controlled by parasites and had lost his mind, but he had always been in charge of the British team, and if something went wrong in this Sino-British cooperation, not only would it be difficult to explain it after returning home, but even his own heart would be blamed for a long time.

He didn't have time to wake up the rest of the team, feeling that if he missed this opportunity, Dr. Smith's life would be at stake. He immediately made a decision, clenched the pickaxe and flashlight in his hand, and chased after him in the direction from which the sound came from.

The sound came from the right side of the stream, in a crack in the rock, and Captain Holden found the hole, but he had to lean sideways to get through.

At this time, the voice calling his name suddenly turned into a series of gibberish, because the distance was too far, the voice was indistinct, Holden only heard the other party saying "let me go" and the like, he immediately became anxious, thinking to himself who this Dr. Smith was talking to, begging to let him go?

Captain Holden is a tall man, and his beer belly has risen due to the indulgence of his private life in the last two years, so he struggles when he tries to get through the crack sideways. But it was okay, he finally passed through it with a lot of effort, and after a narrow gap that lasted for about 10 meters, he gradually entered a relatively wide natural cave. However, Dr. Smith's call was no longer audible.

He continued to go deeper, but unexpectedly came to the shore of a wide underground lake, for Captain Holden, this is simply amazing, this narrow crack, actually hidden a lake the size of a basketball court, at the end of the lake, the water of the underground river flowed in the direction, into another narrower crack, and that crack, no longer normal people can pass through.

Captain Holden guessed that Dr. Smith was hiding somewhere around the underground lake, which was overgrown with rocks and boulders in several places, and he couldn't see it until he got closer. Holden called Dr. Smith's name twice, but the other man did not answer, and he stopped shouting, and immediately fell into an eerie silence.

Holden had no choice but to grasp his pickaxe and follow the rocks on the shore of the lake, hoping to find the lost Dr. Smith in a crack in the rocks, even if it was an attack that awaited him.

However, Holden was sure that with Dr. Smith's thin stature, he would be able to control the opponent in a minute, and the thought of this made him emboldened.

Strangely, when he had managed to walk around the underground lake, he had searched every crevice in the rocks, but he had found no trace of Dr. Smith. He began to wonder if he was hallucinating, perhaps due to the long trek through the cave and the fear for Dr. Smith's safety, which had caused him some kind of hearing illusion.

Holden is the captain of a cave expedition in the UK, having ventured into the famous Mexican Swallow Cave and ventured into ancient tunnels deep in the Amazon jungle, but he has never lost control of the situation as he does now. He thought that even if Dr. Smith was killed, for humanitarian reasons, he would find the body and bring it back to China for burial.

Holden was anxiously walking back and forth by the lake with a lot of thoughts in his head, when he found two rows of footprints on the mud by the lake.

The direction of the footprints is towards the center of the lake, in the shallow part of the lake, you can clearly see the recessed round hole, it is really incredible, Dr. Smith actually rushed into the lake without diving equipment, could it be that the nematoids in his brain have long been tired of the host's body and want to kill him?

Holden did not dare to hesitate, and immediately returned to the camp, woke up the resting team members, and told them what he had discovered. According to Holden's advice, he must immediately put on his diving equipment and dive into the lake to rescue Dr. Smith, but he must find a team member who is also experienced in cave diving, because one of the most important rules of cave diving is that under no circumstances should he go it alone.

The two British team members have not been in the expedition for a long time, and have not yet obtained the qualification certificate for cave diving, only the Chinese vice captain Sun Wu has passed the cave diving exam, but he is obviously still a novice in the sport of cave diving, and has only had a short experience.

Holden was eager to save people, asked Vice Captain Sun to go with him, and told the other party that he was very experienced in diving, and he could rest assured that he only needed him to respond when there was an emergency, but Holden did not explain that it was actually quite rare to encounter an emergency, because few people met could come back alive.

Sun Wu was pressured by Holden to accede to his request, and he demanded that Holden return immediately if no trace of Dr. Smith was found within an hour.

They took their diving gear and made some effort to make their way through the crevasse and into the underground lake. At this time, the level of the lake is as calm as a mirror, and the flow of the lake cannot be observed with the naked eye, but the depth of the lake seems unpredictable, it seems to be at least 10 meters above, and the bottom of the lake is relatively turbid, indicating that there may be some underwater life below.

Holden instructed the remaining three members to keep an eye on the lake, as they would have to come to their aid in the event of an underwater confrontation with Dr. Smith (if the other party was still alive, which was unlikely).

Holden and Sun Wu dived into the water at the same time, the water was cold and biting, and the upper layer was relatively clear, but when it reached the position near the bottom sediment, it suddenly became cloudy, and the visibility was less than three meters. Holden gestured to Sun Wu underwater, warning him not to stick to the bottom of the water, as it was likely to lose contact if the sediment was stirred.

In fact, the water is much deeper than they had expected, and in transparent waters, there are often visual deviations, sometimes looking shallow, but far more than the eye can judge. They descended to a distance of two meters from the turbidity layer and began a carpet search, hoping to find Dr. Smith's body (only a corpse) in the shortest possible time.

Soon, they discovered that there was a strange fish living under the bottom of the lake. The fish was about twenty centimeters long, and had no fear of people, its eyes and pigment had deteriorated, but its teeth were unusually sharp, but fortunately the fish did not attack them, but only floated in the murky water, and from time to time hunted another, smaller fish.

However, when the search was only halfway through, the fish at the bottom of the lake suddenly jumped up in a panic, and Holden was very surprised, not knowing what had alarmed the fish with sharp teeth, but then Holden felt an unusual atmosphere: a huge wave was approaching them at an alarming speed.
