"What... is this?" Zhang Xingkuo sweated coldly behind his back, and his fingers holding the gun could not help but tremble.

Zhao Kuo did not answer, turned on the flashlight with a dark face, walked forward to look at the monster he had just shot.

It was a jungle python as thick as a thigh, with black all over his body, and only the turning scales occasionally flashed a trace of white light.

"Oh my god, such a big crawler, we probably aren't enough for it to get between our teeth." Zhao Kuo cursed and began to check around the python.

"Captain, do you think they will run there?" Zhang Xingkuo tried hard to calm down his emotions, but his right hand pointed at a black hole less than five meters above the python.

"Impossible, this python is probably guarding the entrance of this cave. It is impossible for them to enter there without disturbing the python." Zhao Kuo frowned, not knowing what he was thinking.

At this moment, a scream from Zhang Xingkuo's radio headphones came from, but the static sound in the headphones was also very loud, so I couldn't hear what it was.

The surroundings were so quiet that the sudden sound scared Zhang Xingkuo to death. Zhao Kuo was also stunned. It was obvious that such a sound appeared in his headphones. It took him several seconds to react, and then hurriedly pressed the headphones and listened carefully.

The sound rang again, the static electricity was very harsh, but it was obvious that it was a person calling for help.

"Ge, they are nearby." Zhao Kuo took off his headphones and said with his fingers buckled his ears.

The terrain in the canyon makes the latest radio equipment developed by the United States almost useless, because the signal can only be received within a very short distance. Zhang Xingkuo was debugging along the way, just to receive signals from Sun Guofu and the others, but there was no result. But now the signal suddenly rang, which means that the other party's radio was very close.

Zhang Xingkuo breathed a sigh of relief, and then immediately began to adjust the frequency according to the regular procedure. The sound became clear, but he still couldn't hear what the other party was saying. Zhang Xingkuo was shocked and shouted at the radio: "Where are you in? Repeat, where are you in?"

What came from the radio was a series of indescribable sounds, which had a very serious interference, but the other party's tone changed, and it was obvious that they could hear Zhang Xingkuo's voice.

Zhao Kuo called out again with a dark face, and this time the voice became a little clearer. Both of them tried hard to listen, hoping to hear clearly what the other party was saying.

As he listened, Zhang Xingkuo found something wrong. The person on the other end of the radio seemed not to be talking, or the tone of speaking was very strange and difficult to describe. When he sounded carefully, he seemed to be a person sneering.

Zhao Kuo was also confused. He stopped calling, but continued to debug the radio, hoping to make the sound inside clearer.

The debugging was useless, but the sound rang a little immediately. They put it on their ears again, and it became clearer. The sound was really like a sneer. It sounded so resentful, it was not made by a normal person at all, but like the sound of a madman in a madman in a madhouse. But after listening carefully, I felt that after the laughter, there were some other sounds, which were very slight. The two sounds were mixed together, and in the jungle full of terrifying colors along the way, it was quite strange.

"No, definitely not." Zhao Kuo's face darkened again, pointing to the radio and said, "The frequency of this sound is very fast, and the tone is almost flat, unlike human laughter, it should be mechanical sounds. It may also be someone constantly grabbing the radio intercom with his nails, and the sound of static electricity has become like this." Zhao Kuo said while demonstrating with his hands.

"Catch the intercom with your hands? Why do they do this?" Before Zhang Xingkuo finished speaking, his face changed at the same time, and he suddenly realized something!

"They must be in some place, not yelling or talking, they can only contact us in this way."

"Ge! These two two are out of stock, so they must be nearby. I fired a signal flare and asked Dr. Li and the others to come over. We are not familiar with this ghost place and cannot go in rashly." As Zhao Kuo spoke, his eyes involuntarily looked at the hole above, and his fingers holding the gun looked a little white.

Not long after the signal flare was sent, William rushed over with the remaining people. They were not many, but they also made the black canyon a little more angry, and it didn't seem so scary.

"Professor, what do you think?" Zhao Kuo poked the python he had just killed with a butt, and asked respectfully.

"In such an environment, it is normal for animals such as snakes to have such a body shape. The only thing that puzzles me is that this python should be considered a non-toxic snake according to its body shape, but why is it not only poisonous, but also so toxic?" He pointed at one end of the python's corpse, where the originally black stone had been silently corroded into a big hole by the blood flowing out of the python.

"Don't think about these things for now. Zhao, according to what you said just now, your two team members should enter the hole above." William frowned and said with an unnatural expression.

"Are you sure?" Zhao Kuo swallowed a mouthful and his face turned a little darker.

"This kind of radio has a great disadvantage. In such terrain, only a gap terrain similar to this hole can send signals, so they must be inside." William's tone was firm, which made people unquestionable.

Everyone was speechless. In such an environment, deviating from the original marching route to rescue was obviously not a very wise decision. However, Sun Guofu and Wang Fatty were both people who were equivalent to the mainstay in the entire team. Without them, the risk of this mission would increase dramatically.

Zhao Kuo and William looked at each other, then nodded to each other.

"Scott, go up and take a look, be careful," William said the first.

At this time, Zhang Xingkuo stopped him and said, "I'll do it. I've climbed many such cliffs before, and I'm definitely more experienced than him." Without waiting for others to speak, he took off his backpack, opened his mouth and bit a dagger, and then used the dagger as a mountaineering pickaxe, and began to climb upwards.

He moved very quickly and his posture was as quick as a monkey. Zhao Kuo and his friends used flashlight to shine him on the road. They almost didn't have much effort to see him crawling to the entrance of the cave. He found a position to stand firm, then pulled up a cold fireworks and threw it down at the entrance of the cave.

Zhao Kuo and others could only see his movements below, but they couldn't see what he saw. They were very anxious and began to ask, "What's inside?"

"I don't know." Zhang Xingkuo scratched his head on it, his expression was very confused, and then said: "This... this seems to be an airplane."

"Airplane?" The people below looked at each other.
