The light inside was not very clear, and Han Du couldn't see the specific appearance clearly, but judging from the movement caused by the turning of the stone slab, the space below was very large.

This means that Han Du has found the right place, thanks to the leopard.

Han Du immediately took a breath and let out a loud shout, and the stone slab was completely lifted by his arms, and the whole ground turned over, overwhelming the large grass.

Now that time is pressing, Han Du immediately picked up the folding shovel and set off into the underground space, the headlamp illuminates the steps step by step, and you can see that it is covered with dust, and every step can leave a footprint.

This clue was also noticed by Han Du, indicating that there should be some holes or entrances in other places, otherwise the steps would not be covered with dust.

The steps were thirty meters long, and when Han Du went down to the ground and stepped on it with his feet, the ground was very hard and paved with cement.

He turned his head and walked around, with the help of the lighting of the headlamp, he could see that there were many traces of fixed machinery and equipment in this underground space, such as small potholes arranged in a regular manner, some square concaves, and even a few production lines that had not been removed.

Han Du looked into the distance again, where the headlamp shone through, until about twenty meters away, he could see the edge wall of the underground space, which was painted with the words "715 Project Area", and the place where Han Du came down was actually located in the center of the underground space, with a distance of about twenty meters in all directions.

In this way, this is a large room of 1600 square meters.

It is estimated that in the 715 project area of that year, the personnel lived above and worked in production below.

Han Du walked in such an empty and huge place, there was no fear in his heart, it seemed that he had gone out to explore during this time, he carried a folding shovel and searched inside, hoping to find the Medal of Honor left by the simple worker as soon as possible.

There are also some miscellaneous items piled up here, such as some large sealed barrels for unknown purposes, piles of empty large cardboard boxes, and rows of neat wood, etc., I don't know what to do.

Han Du searched around these things in turn, hoping to find the remains of the simple worker while searching for the Medal of Honor, and according to the contents of the mission description, Han Du guessed that his remains were still in them for some reason.

At this time, the leopard did not follow up, and it did not know where to go outside.

Han Du was enough for one person here, and after searching around the large sealed barrels, large cardboard boxes, wood piles and other things, he found nothing.

This 1,600-square-meter underground space looks very large, but everything is clear at a glance, and the difficulty of Han Du to find it is not that high, but after looking around, Han Du just didn't find anything, which made him a little bored.

At this moment, Han Du, who was standing in a daze, moved his eyes, because with the help of the light of his headlamp, he found a bunch of things in the dark next to him, this was a corner, and he hadn't found it before.

With some anticipation, Han Du walked over quickly, and under the light of the headlamp, there turned out to be a pile of white gauze for unknown purposes, all of which were fifty centimeters high.

For some reason, this pile of white gauze gave Han Du a very strange feeling, he bent down and reached out to take a look at the white gauze. At this moment, Han Du's pupils must have been fixed, and the hand that was stretched out stiffly did not move, because he suddenly found that under the white gauze, there was a mass covered with white scales lying on his stomach, showing a large disc shape enclosed by him.

The color of this clumped, white scales thing looked very clean, a little whiter than white gauze, and after Han Du saw it, he immediately reacted, it was not a huge white snake!

He held his breath and found that the white snake had buried its head in the gauze and seemed to be asleep, so he didn't find him, which was also considered a lucky thing for him.

This white snake was a little bigger than the big black python he had encountered in the abandoned tunnel last time, and its waist was as thick as an adult's thigh, Han Du pressed the headlamp and slowly retreated, moving lightly, for fear that it would wake it up.

After retreating for about ten meters, Han Du piled up behind a pile of wood next to him, quietly paying attention to the big white snake under the gauze, thinking about how to get rid of it, otherwise he would not be able to carry out his mission smoothly tonight.

Just as Han Du was deep in thought, there was a slight sound in the darkness in the distance opposite, and gradually, Han Du could see what it was clearly, and his pupils suddenly constricted.

He found that they were small snakes with thick wrists, and they were only compared to the size of the big white snake.

These snakes came in from a small hole in the wall in the distance, there were seven or eight of them, some black, some earthy, and some flower-colored, and they all had a characteristic in their mouths, each of them biting a dead animal, Han Du could vaguely see that there were mice, gray birds, hares, and even a flower snake biting an old hen in its mouth.

Han Du was very curious about why they caught their prey but didn't eat it, and brought them all here. Soon, he understood, because these snakes sent their prey to the gauze, and the big white snake that was sleeping in the gauze heard the sound of the prey falling to the ground, and woke up, and the body covered with white scales twisted and opened, and the snake's head also came out from under the gauze, and a long snake hyacinth swallowed non-stop.

It then lowered its head and bit the old hen, swallowed it whole, squirmed in its belly, and began to eat the hare.

Han Du, who was hiding in the shadows, saw this, and finally understood, it turned out that this big white snake did not hunt by itself, and enslaved and drove a group of small snakes to be his subordinates, and they preyed for it, and sent it here, and he didn't know how it did it.

In nature, it is rare for large animals to be fed by small animals, but the world is so big that there are no surprises, and it is not impossible for such a case to occur occasionally.

Han Du guessed that when the big white snake finished eating its prey, the little snakes would all leave, so he continued to wait patiently.

Suddenly, he felt the mobile phone on his body shake, as if something had been sent, he hurriedly hid behind the pile of wood, took out his mobile phone and looked at it, the message prompt showed that it was a message from that exploration forum, and the sender was "Heavenly King Gaidihu 666".

He clicked on the message and looked, it turned out that this person had sent several messages to Han Du and he didn't reply, so the other party sent a shaking reminder.

The message reads, in order: Are you still there? I've arrived at the east side of Yandang Mountain, and I'm coming to you right away!

My mother, let me tell you, don't wander around Yandang Mountain, just now a big vicious dog chased me around and almost bit me!

Tell me back, I'm scared here alone in the middle of the night!

After reading it, Han Du suddenly couldn't help laughing, because the big vicious dog chasing this person everywhere should be a leopard, but with the ability of a leopard, he was able to escape, I really don't know how he did it.
