Following the clues, Gao Dan found another mysterious exit inside the Hongyang processing plant. Who would have thought that this old, dried-up well actually had a problem?

It was by sheer coincidence that I accidentally kicked a stone down; otherwise, I really wouldn't have noticed.

Just as Gao Dan was about to go down, someone patted him on the shoulder from behind: "Boss, it's me." Instructor Zhao's familiar voice rang out.

Clearly, Gao Dan paused for a moment: "What are you doing here?" he asked, frowning.

"Boss, I'm not a greenhorn, this is a battlefield!"

Since they are soldiers, how could they possibly retreat from the battlefield without a fight?

Gao Dan looked at the person in front of him for a few moments and said, "Then let's go down together."

If you look closely, you can see that Commander Gao's eyes are full of satisfaction.

Seeing that his boss wasn't going to hold it against him, Zhao Shuai chuckled and said, "Alright! I'll go down first and check out the situation down there."

"careful."

As Zhao Shuai jumped down, he immediately inserted two military daggers into the inner wall to ensure that he would not fall down instantly, since no one knew what might be down there.

Is it hitting the bottom, or methane gas, or a trap?

The well wasn't very deep, about three meters high. After Zhao Shuai went down, he picked up a few small stones from the inner wall and threw them one by one into the well bottom, which was covered with weeds.

"Boss, there's really something wrong here," he shouted, looking up at the well opening.

Upon hearing this, Gao Dan jumped down from above, using the same method that Instructor Zhao had used before.

There should be an exit below.

Hearing this, Instructor Zhao agreed wholeheartedly. Otherwise, the two of them would have turned the entire Hongyang processing plant upside down, only to find nothing. It was too strange.

So far, this ancient well is the most suspicious one.

The two exchanged a glance, then simultaneously drew their daggers and jumped down. As they descended through the weeds to the bottom, they indeed saw a hole about the height of a person, through which light was shining.

"Boss."

"Yes, this is it. Let's go in and take a look."

"good!"

...............

The tunnel dug out inside the cave wasn't long, only about five or six meters. The two of them quickly reached the end and, naturally, saw the old-fashioned elevator standing there.

The elevator was clearly covered with bloodstains of varying shades, some of which were quite fresh, indicating they were no more than six hours old.

So, just six hours ago, another victim died?

Neither of them looked well, and a chill permeated the entire tunnel.

"Go up!"

Upon hearing this, Zhao Shuai snapped out of his reverie and said in a slightly hoarse voice, "I hope this can prevent the next victim from being harmed."

Gao Dan didn't say anything more and took the lead in climbing up, with Instructor Zhao naturally following closely behind.

After the two went up, they immediately hid themselves and then began to survey their surroundings.

“Hongyang Factory, it really was a smokescreen. This is where the real secret laboratory is located! Boss, right?” Zhao Shuai gripped a clump of weeds tightly in his hand.

"Be careful, the security here is definitely tighter than at the Hongyang Factory."

"I understand, boss. Be careful too. This time, we must wipe out these Japanese people's hideout and make sure they don't leave alive! Don't even think about doing anything on our Chinese turf!"

Just as the two were about to leave, they heard someone approaching from not far away: "Where's Lao Liu? Why isn't he back yet? Seven experimental corpses were just brought out of Lab One. Hurry up and get Lao Liu over here to dispose of them." The speaker sounded very anxious.
