After all, this fluorescent agent is something only time travelers would know about.
It's quite easy to produce this fluorescent agent; you just need to extract some minerals.
Now, when Xu Yuehuai sees the traces left by the fluorescent agent, she feels a strong sense of familiarity.
Although in Xia Sen's eyes, all of these were just strange symbols and patterns.
But in Xu Yuehuai's eyes, they were nothing more than Arabic numerals and map markings.
Xu Yuehuai felt that these symbols and patterns seemed to be conveying some kind of message!
"This information is extremely important; it could probably guide us on where to escape."
"Sister, is this true? Then I'll help you find these symbols."
As Xia Sen spoke, he then followed the symbols on the wall to search for clues. After searching for a long time, he finally found many clues.
He touched the patterns on the wall with his hands and kept walking to the side.
"Sister, this pattern looks different. Why is it suddenly protruding a bit?"
After hearing this, Xu Yuehuai looked in his direction.
Then I saw something special in that area.
"Don't touch that area again!"
"This area is unusually strange!"
Xu Yuehuai quickly warned Xia Sen.
But Xia Sen was too late; his hand had already touched the object.
Then there was a click, as if some mechanism had been activated, suddenly triggering a hole behind the wall.
"Sister, there seems to be a cave here. I wonder if it leads to other places."
"This area might be dangerous. You stay here for now, I'll go check it out myself."
As Xia Sen said this, he quickly told Xu Yuehuai to stay there for the time being.
Xu Yuehua nodded, intending to stay where she was and observe the situation of those people, so that they wouldn't discover anything unusual about the place later.
Xia Sen then carefully entered the cave. After passing through a dark passage, he suddenly noticed something ahead.
He kept walking forward and easily made his way to the front.
As he walked further inside, he discovered that it was actually a hidden secret room.
I never imagined this place was a secret room!
He walked around the area, then picked up a stone from the ground, struck it to create some sparks, and lit a candle nearby.
Once the candles were lit, they illuminated everything around them.
“These things all seem to be very ancient.”
"These look like some lost books!"
Xia Sen hadn't read many books, but seeing how old those books were, he knew they must be very important.
He quickly took off his coat and then immediately wrapped all the books and scrolls inside it.
After finishing all this, Xia Sen quickly came out and left the place.
They followed the original passage back to find Xu Yuehuai.
"Sister, look what I found!"
As soon as Xia Sen came out, he spoke to Xu Yuehuai in secret.
Xu Yuehuai examined the items carefully, and then became somewhat surprised.
"These are all ancient books and scrolls! Where did you find them?"
Xia Sen immediately pointed to the passage inside, which had now been closed up again and was no longer visible.
“I found them in there. I felt that these must be some very important things, so I took them all out and showed them to my sister.”
"Sister, can you understand what all of these things are?"
“These things seem to record the history of this place.”
After carefully examining the documents, Xu Yuehuai slowly spoke to Xia Sen.
"This area was originally an old medical facility where some doctors conducted numerous experiments, specifically researching various deadly diseases!"
“At first, they sent some seriously ill people here, but later the number of people being tested decreased, so they started to capture seriously ill people from the surrounding areas and bring them here.”
"I suspect that the people who brought us food were the ones who were captured for research."
"And they were captured and brought here, forever losing their freedom. After being used as test subjects by those people, they lost their value and were reduced to being like servants."
Xu Yuehuai thought that they might have been captured to test the medicine, after all, Xu Yuehuai had previously contracted the plague.
She already had antibodies against this plague. After the other side learned about her situation, they captured her and Xia Sen. At first, they didn't resist them much, perhaps because they wanted to use her to test the antidote for the plague.
"We must leave here," Xia Sen said firmly. "Otherwise, my sister will be in danger if she stays here!"
"We can leave through this passage now, sister. Let's hurry and get through here."
Xu Yuehua nodded in agreement, "Then let's leave here quickly. The people here are utterly heartless, and this area is extremely dangerous. We can't stay here and wait to die. Let's get going now."
After discussing it for a while, the two began to plan how to escape from this place, and then they immediately went to open the passage they had just been in.
They started by putting their coats on some straw, making the straw look like them, and then laid the fake scarecrow flat on the ground, pretending to be sleeping.
"Sister, your idea is really good. They will never find out that we have secretly escaped."
Xia Sen smiled, then secretly left with Xu Yuehuai. They immediately walked out through the secret passage.
Originally, one of these passages led to a secret room, and the other led to the outside world.
Xu Yuehuai thought that the other party must have deliberately left two passages, and that the other passage would probably be closed after they left.
When those people come looking for them, they will definitely not find that they have already escaped through the secret passage. If they cannot find another passage, they probably will have no way to catch them.
They arrived at the edge of the forest, where everything was quiet and still in the deep of night.
"Sister, we've finally escaped! We've finally regained our freedom!"
"I've been stuck there for days, and I'm going crazy from being cooped up."
"I never thought we would actually succeed!"
Xia Sen was extremely excited; he hadn't expected to actually escape.
Their efforts, though numerous, were not in vain.
"Okay, now that we've escaped, let's get out of here quickly. Don't linger, or we'll be finished if they catch up with us."
Xu Yuehuai didn't want to be captured and used as a drug user along with Xia Sen, so they quickly fled the area.
