If it is really a four-dimensional space, then the stone chamber below is almost endless, which may not be helpful for this exploration, but it has far-reaching significance for Huaxia University, which is another major discovery...... Four-dimensional space!

At that time, Huaxia University can carry out a series of research verifications through this discovery, and if it can master this technology, it is not impossible to realize time and space travel back to ancient times, or to the future......

"It is worthy of being the daughter of Principal Gao Yu! Everyone will follow Gao Yi's proposal and enter the passage at the same time! ”

Professor Yan looked at Principal Gao Yu with an inquiring gaze, and saw Principal Gao Yu bowing slightly, so Professor Yan arranged it directly.

"Yan Ju and Professor Yan are guarding above, if there is any problem below, they can help in time!"

"Good!"

"Hmm!"

President Gao Yu arranged a group of students from the Department of Archaeology of Huaxia University, and he asked the students who were about to go down the passage to connect them with ropes, so that the students who were about to go down the passage could be gathered together as much as possible.

After all the preparations were completed, Principal Gao Yu took the lead to the edge of the pit, and Yan Ju took out a hanging ladder from a toolkit in the corner, which Shi Mukun was still puzzled about, the hanging ladder was fixed from top to bottom, and for the dimensional space, it should also belong to foreign things, why as an item from outside the passage, it has uniqueness, but it can penetrate all planes of different spatial dimensions.

This seems to be inconsistent with the theory of spatial dimension, because in the four-dimensional space, although there is more time dimension, the objects or people who enter it are all unique.

Otherwise, the same person will appear and exist in different time and space at the same time, so will this person be dismantled, or will he copy countless versions of himself, and what happened to himself in each plane is still considered his own? This theory is clearly untenable......

"Everybody turn on the button intercom! I'll go down first, and then everyone will come down behind Shi Mukun, if you have any problems, remember to try to contact other students, or just go back to the stone room and wait! ”

After Principal Gao Yu finished speaking, he followed the hanging ladder into the black pit.

As soon as Fang entered, the smart bracelet worn by President Gao Yu glowed, it seemed that the smart bracelet awarded this time was different from the one awarded in the entrance examination of the Department of Archaeology of Huaxia University and the Memory of the World Competition, this smart bracelet was able to emit light in a dark environment on its own.

"This smart bracelet is made of a fluorescent material and other materials, which can emit light on its own in a dark environment, without consuming energy and not afraid of water. The reason why fluorescent materials emit light is because they themselves have been in a fission state, and the fission cycle can persist for hundreds of years! ”

Professor Yan saw a group of students staring curiously at Principal Gao Yu's smart bracelet, and explained one by one.

"Of course, the fission of this fluorescent material will not stop halfway, so when you don't need to use the light source, you will be like me......"

Everyone saw that Professor Yan pulled his sleeve and directly covered the smart bracelet, and immediately felt that this tall and noble smart fluorescent bracelet could be regarded as a pearl secret cast, and it was too unparticular to use it like this!

"Shimukun, don't be stunned, it's your turn!"

Gao Yi looked at Shi Mukun with a look of disdain, and Professor Yan pulled his sleeve to cover the smart fluorescent bracelet and reminded.

"You're welcome, Ms. Gao Yi! You can go down first, don't wait for me! ”

"Who is waiting for you, this is the principal's request!"

"Headmaster's request?!"

Shi Mukun then remembered that when Principal Gao Yu went down for the first time, he did explain that he would let the other students follow him, because Principal Gao Yu did not use a rope to connect with the students, so for these people now, he is equivalent to taking the lead!

Shaking his head helplessly, Shi Mukun felt that Principal Gao Yu must be intentional, Principal Gao Yu is a master of the half-legged Heavenly Master Realm, and it should be the first time, he has just entered the door when he says it sounds good, so he will arrange for himself to take the lead, isn't this a pit for himself!

"Hurry up! There are so many students waiting behind us! ”

"I don't block potholes, I don't get in the way! And it's such a gentleman's person, you just go down first! ”

Regarding Principal Gao Yu's arrangement, Shi Mukun directly ignored it, he was his junior brother, so why did he let himself take the lead.

"The headmaster has to make arrangements that cannot be violated, you hurry down!"

"That's right! Hurry down! ”

Shi Mukun was very tired of the words of the group students of Huaxia University, and he was also well aware of the influence of President Gao Yu, so he had to pull up his sleeves and climb down the suspension ladder!

The feeling of someone under the suspension ladder is different from that of no one, and when he grabbed the suspension ladder, he felt that there was no one under the suspension ladder at all.

"It's only been a while, Senior Brother Principal is in the end, it seems that Senior Brother Principal is usually too low-key to hide his strength, he is really old and strong!"

Shimukun muttered, and went down the suspension ladder a little faster.

Because of the connection to the rope with other students, the upper convenience was quickly pulled, and then someone above also went up the suspension ladder.

Next, his downward speed was affected by the speed of the students above, and he could only stop and go, but this made him feel that time had passed so long!

Until a certain moment, he saw the bottom of a stone chamber through the closing line of the smart fluorescent bracelet.

At the same time, the pulling force of the students involved above also disappeared in an instant.

He thought it was because the students above him were too close to him, so the pull force between them disappeared, so he sped up his descent, and when he stepped on the bottom stone chamber with one foot, the rope above fell from itself.

While being surprised, Shi Mukun picked up the piece of rope and looked at it carefully, and he found that the rope was very flat at the break, not torn off, and looked like it had been cut directly by a sharp blade.

"It can't be the ghost of the Huaxia University team members, right?"

Shi Mukun was puzzled, but after thinking about it, he felt that it was unlikely, because the students in the group of Huaxia University had not offended themselves, but many of them still successfully passed the entrance examination of the Department of Archaeology of Huaxia University because of themselves!

"Since it wasn't made by the members of the Huaxia University team, how did such a flat incision be made?"

Of course, what made Shi Mukun even more puzzled was that the suspension ladder was actually hung well, although he couldn't feel that there was someone above, but it was not cut like a rope.

With a suspicious mood, Shi Mukun carefully looked at the first stone room he encountered after coming down!
