Mecha Star Wars.

Why is there mud on the roof of a limestone cave?

Not only is there soil, but there are also a few roots hanging down.

Xue Ping was very excited. "It's directly above. Is it possible that it was originally a hole, but was later filled with soil as vegetation grew?"

Who knows?

"Lin Fan's current location is about sixty or seventy meters away from the top of the mountain." John Woo began to calculate. "Deduct about thirty meters of the cave itself. That means there is still about forty meters of thickness at the top."

"If the top part is really a hole, just filled with soil..." Before Wu Yusen could finish his words, Xue Ping stood up.

"I'll go over and take a look at the situation. You guys, bring your digging tools and follow me."

Guessing it a hundred times is worse than actually seeing it once. Xue Ping is an activist.

Lin Fan had no control over what happened above. She suddenly thought of something else and looked down.

Sure enough, there was a thin layer of soil around where she stood. It should have fallen from the top.

"Footprints!" Lu An followed the direction of the light and saw the footprints on the soil at a glance.

Because of her circling, the feet of the stars had become blurred and could not be seen clearly. But there is also a series of shallow footprints extending into the distance.

Lu An could even see clearly the lines and the 42-digit number on it.

"It's Feng Chuang!"

The footprints looked very fresh, and it was a bit far-fetched to say they were left by the pile of dead bones beside the wall.

Unless there's someone else here.

There was no time for the surveyor to refine the details, so Lin Fan hurried forward in the direction of the footprints.

Her mission here was to save people. In addition, there is a time limit in the stars... nothing is more important than saving people at this time.

"Looking at his footprints, it seems that his legs and feet are not injured." Lu An judged from the fact that the strength of the two footprints was the same and the stride length was basically the same.

"That Feng Chuang is quite powerful. He came down from such a high place without getting hurt." Lin Fan said as he walked.

Fitness instructor Lu An rolled down a slope more than 30 meters high and twisted his foot.

Photographer Feng Chuang came down from a 20-meter-high, almost vertical wall with only some protrusions that were difficult to grasp, and he was still intact...

"Ah, you just wanted to tell me..." Suddenly remembering the previously interrupted topic, Lin Fan asked John Woo.

"That's what you just thought of. After I saw the environment on the wall, I felt that Feng Chuang's skills were very good."

John Woo looked at the Feng Chuang file sent by other employees and found no problems.

At least there seems to be no problem on the surface.

"As for that wall... I guess I wouldn't be able to do it with my bare hands." Lin Fan weighed his ability in his mind.

The bumps on the wall were not too close together, and given her height, it was difficult to reach them even after stretching her limbs. There is a high probability that it will fall.

Of course, this just talks about her own quality. Then asked John Woo again. "can you?"

"I should be fine." John Woo nodded. Such an environment was nothing to him.

But who is John Woo? Song Ren, the former "God of War" of the special forces team, admired him. Just because he can do it, doesn't mean others can do it too.

Lin Fan, who was tied with Song Ren, certainly knew that their physical fitness was achieved through long-term and high-intensity training.

So how could Feng Chuang do it?

Lin Fan turned around in his mind several times and formed several guesses. But because Lu An was still in front of him, it was difficult to speak.

"Be careful." John Woo warned.

With just these three words, Lin Fan already understood it, "I know."

Following Feng Chuang's footprints, Lin Fan quickly entered a place similar to an alleyway. It's somewhat similar to the place they came out just now.

It's just that this entrance is directly on the ground, instead of hanging in mid-air like the entrance of the cave they came down from.

After walking a few hundred meters and passing a few turns, a T-shaped intersection appeared.

"How do we go here?" Lin Fan asked John Woo for help.

Look left, look right, both sides seem to be the same.

I hate choosing the most. Lin Fan thought to himself.

"Just pick one and go." John Woo couldn't give any good advice.

The top, bottom, left and right are all square stones, only the front and back are empty. The endless passages reminded John Woo of tomb passages.

However, most of the tomb passages are made of solid granite, and I have never seen one made of limestone.

Lin Fan couldn't make a choice, so he simply stood at the fork in the road and silently recited, "Point your troops, point your generals...". As a result, before the long string of words was finished, a "boom" came from the left.

It wasn't exactly a loud noise, but it was very noticeable in the silent space. Lu An even trembled with fright at this sound.

problem occurs!

Lin Fan groaned secretly in his heart. He levitated directly and flew quickly in the tunnel.

Lu An was carried by her speed and clung to Xingchen's breastplate, his hands unconsciously clinging to her shoulder armor.

It’s not that I don’t want to hug my neck, my hands are not long enough…

The sound of "rumbling" was continuous, and Lin Fan quickly found the place following the sound.

I saw only one person, probably with a cold light tied to his body, which made the surrounding area appear green. She was running desperately in the direction she came from.

Behind him was a huge stone ball, pressing against his back and crushing forward.

"It's Feng Chuang!" Lu An glanced at him and shouted.

Feng Chuang was flashed by the sudden light, and his eyes suddenly became dark. He just moved forward based on instinct, but his speed was inevitably affected.

He was about to be hit by the ball.

Just as Lu An was about to scream loudly, he felt himself slipping to the ground. Before he could react, the mecha sister had already ducked behind Feng Chuang, raised her arm, and blocked the stone ball that was close at hand.

Lu An's eyes widened. My heart was beating hard.

Feng Chuang hadn't noticed it yet and was still running forward.

I don’t know what kind of material the stone ball is made of, but Xingchen can easily grab a handful of powder without using any force with his hands.

Lin Fan also breathed a sigh of relief knowing that this thing was so weak.

It was just instinct to rush forward. She was actually not sure whether she could handle this thing. Since there is no threat now, it is naturally the best.

As soon as he let go, the stone ball that was originally stationary began to roll again.

Lin Fan hurriedly resisted, gathered strength in his arm, and sent it gently. The huge stone ball instantly turned into powder and fell down.

Suddenly, a black shadow shot out from the powder. Lin Fan had no time to react and subconsciously reached out to catch it.

When I took it in front of me, I saw it was a dark green, crystal-like thing. The shape is quite regular, and the stars can be wrapped in one hand.

"There is a sealed bag in the waterproof bag, put it in quickly." John Woo sounded a little anxious.

Usually, special agencies are more vigilant when dealing with unknown substances.

If conditions permit, complete protective measures must be taken before contact is possible to prevent harmful substances from being attached to unknown objects.

Although Xingchen appears to be indestructible, due to her unique biological attributes, the mecha can sense all feelings from the outside world to Lin Fan.

In other words, if there are harmful substances that the stars cannot resist, then the damage Lin Fan will feel will be at the same time.

But this time the accident happened suddenly. Before he could say anything, the thing was already in Lin Fan's hands...

Now we can only remedy it quickly and hope this thing is harmless.

"Try to avoid those two people and don't let them see you." John Woo also specially warned.

It seems that this place is definitely not as simple as a natural cave...
