"Don't worry about that."

"The guy selected by our Huo family didn't instigate anyone."

"Since they came in with me, they won't turn back." Mrs. Huo said confidently.

The guys standing behind her were also with their heads up.

It seems that he is quite dissatisfied with the fact that Su Mu looked down on them.

In protest too.

In this regard, Su Mu just smiled.

"That's for the best!"

"When the flame is lit, it generates a lot of heat, so let's move everyone into the waterhole first."

Hearing this, Huo Xiuxiu looked at the waterhole below.

Squatted down and tested the temperature of the water with his hands.

In an instant, Bing retracted his hand.

"This ...... The water is too cold."

"Brother Su Mu, my grandmother has just been discharged from the hospital and is weak."

"She...... Is there any way to keep her from going into the water?"

Without waiting for Su Mu to answer, Mrs. Huo stopped Huo Xiuxiu.

"Don't listen to her, I'm fine!"

"Grandma'......"

"Xiuxiu, I'm fine, I know my body."

"Brother Su Mu, let's follow your plan together!"

After speaking, the old lady Huo walked straight towards the waterhole, and stepped in without blinking.

When the other guys saw this, they followed behind and went into the water.

Huo Xiuxiu looked worried and walked to Su Mu's side.

"Brother Su Mu, can you please help me take care of my grandmother, I must not let her have anything to do!"

Huo Xiuxiu's eyes were red, and she looked pitiful.

Anyone who saw it had to feel pity and agree to her request.

But Su Mu is not an ordinary person.

He never liked what promises couldn't do.

On this trip, he could feel that Mrs. Huo herself had never thought of walking out of this Zhangjia Ancient Building alive.

And these are not things that Su Mu can change.

"I'm sorry, all I can say is that I did my best, but everyone has a life."

"As for what will happen after entering the Zhangjia Ancient Building, I can't guarantee it!"

Leaving these words, Su Mu turned around and walked towards the waterhole.

"Tut-tut, this little appearance of Huo Xiuxiu's red eyes makes me feel protective!"

"I have to say, this Huo Xiuxiu is really good-looking, Si Ha Si Ha!"

"Don't be ha, no matter how good-looking you are, it doesn't matter to you, people like people like Su Mu!"

"It's a pity, Su Mu is not the kind of person who will pity anyone, even in the face of Huo Xiuxiu, he looks like a straight man!"

"I think this is very good, it shows that Su Mu is a single-minded person!"

"This family is really good at designing, they actually put fire oil in this crack in the stone, I don't know what a spectacular scene it will be after ignition!"

"I don't care if it's spectacular or not, I only care about what will happen after this mechanism is opened, and whether Su Mu and them will be in danger!"

"It's exciting time again!"

"Eh, do you feel that there is something magical about this, as if there is a force pushing them to find all this feeling in the dark......

I have to say that there are still capable people among this masses.

At a time when many people were amazed by the wonderful design of Zhangjia Ancient Building, and shocked by Su Mu's ability to guess the mechanism.

There are still people who vaguely see that behind this is the big hand that drives the development of everything.

Of course, they only felt it a little, and they didn't expect that the big hand behind this was Su Mu himself.

Moreover, these discussions were quickly drowned out by other discussions.

At this moment, everyone has entered the waterhole.

And Su Mu was holding a lighter in his hand, and after lighting it, he threw it towards the gap in the cave wall.

He threw it with great accuracy.

The lighter drew a perfect arc in the air and landed successfully in the gap.

In an instant, the oil was ignited.

The tongue of fire spiraled and spread rapidly towards the top of the cave wall.

The entire cave was instantly illuminated by flames.

The scene was so spectacular that everyone stood in the waterhole and looked stupid.

When they first entered the pool, everyone was still shivering with ice from the cold water.

However, when they saw the flames that surrounded the entire cave wall, they completely forgot about the cold.

One by one, they opened their mouths and stared blankly at this scene.

Until the flames of the entire cave wall were ignited, everyone found that at the very top of the entire cave entrance, there was a small ancient building hanging upside down.

"Look there!"

"Then, is that the Zhangjia Ancient Building?"

"W-It's too small, this looks like it's just a model!"

"Could it be that this Zhang family has mastered what secret method can make this ancient building bigger and smaller?"

Everyone's speculation is gradually outrageous.

Fortunately, Xiaohua and Mrs. Huo still kept their senses.

They knew that it wasn't magic, and there must be other doorways in it.

It's just a pity that they can't see it themselves.

"Su Mu, can you see what the hell is going on?"

Xiaohua said with the attitude of asking if she didn't understand.

Su Mu nodded and laughed.

"Actually, the principle behind this is very simple."

"Speaking of which, like the metaphor just now, it is indeed a kind of magic!"

Magic?

Hearing Su Mu say this, everyone was stunned.

The device that made them feel extremely surprised for such a long time turned out to be a kind of magic.

Aren't they being turned around by this kind of magic?

Su Mu continued, "It's just that this magic came from Persia!"

"There is a magical stone in Persia called the Moon Stone."

"This stone cannot reflect the sun's rays, but it can reflect the moon's rays, hence the name!"

"The reason for this is that it can only reflect cyan light."

"For example, we just hit this mirror with a flashlight, and the cyan light reflected from this mirror reflected on the Zhangjia Ancient Building above."

"So we saw the Zhangjia Ancient Building in the mirror!"

I see.

Indeed, as Su Mu said, many things will feel extremely magical when you don't know the principle.

And once you know, that's it.

The setting here, in the final analysis, is a magical stone.

It's not magic or anything like that.

"But if it's just a reflected light, why are we standing here and not blocking the light?" Huo Xiuxiu asked.

This is one of the reasons why they were puzzled at first.

"That's because there are many of these moon stones on the walls around here."

"The light is refracted by them, and the angles are very complicated."

"That way, we won't be able to affect the reflection of the light." Su Mu explained.
