"Everyone, be quiet!"

Principal Gao Yu stretched out his hand and signaled everyone to be quiet, "Next, Instructor Chu will teach everyone how to snorkel!" ”

As soon as President Gao Yu finished speaking, Commander Chu waved to the place where the staff of Huaxia University stood on the plank road, and the staff of Huaxia University, who had been waiting there, brought over the diving equipment that had been prepared.

"It's just the low tide now, so after putting on the diving equipment for a while, you can jump down if you can use it, and you can't use it and climb down the escalator, and I'll teach you how to use it below. Do you understand? ”

"Got it!"

Hearing the answers of the students of Huaxia University, Commander Chu began to pick up the diving equipment brought by the staff of Huaxia University, and explained while wearing it:

"Because before I came, I asked everyone to change into swimsuits and swim trunks, and everyone put on the wetsuits directly after a while! Like me."

"After putting on the diving suit, put on the oxygen cylinder on your back, put on the diving goggles, bite the plastic body connected to the oxygen cylinder with your teeth, and remember that you can't breathe through your nose after entering the water, you can only breathe with your mouth!"

"Because the buoyancy of the water, coupled with the fact that the sea water is salty, the buoyancy is greater than that of fresh water, so you have to tie this weight-bearing belt, otherwise it will be difficult to dive into the sea."

"After all the above wetsuit work is done, let's learn the gestures after entering the water, the situation on the bottom of the sea is complicated, and unexpected dangers can be encountered at any time, so we need to work as a team and help each other. Especially the collaboration between the students in each group! ”

"Look, you look at it, the thumb up, pointing upwards means floating upward; Conversely, if you raise your thumb and face down, it means you dive down"

After the commander of Chu finished the diving equipment in detail, he was the first to jump into the sea, only to hear a "bang", and six or seven seconds later, the commander of Chu, who was wearing a diving suit and carrying an oxygen tank, poked his head out of the sea and waved his hand to the people on the plank road to jump down.

One hundred students from the Department of Archaeology of Huaxia University and one hundred students from the Department of Archaeology of Huaxia University jumped into the sea one after another.

Watching an individual jump, because there are basically people in each group who can snorkel or someone in the group who can snorkel, will cheer up and encourage other students below.

Until Shi Mukun was left standing alone on the plank road, putting on his snorkeling equipment neatly, and then climbing down the soft rope ladder under the surprised eyes of a group of teachers and students of Huaxia University.

"Landlubbers!"

Seeing Shi Mukun's behavior, Ji Chen and Dongfang Yifeng both said disdainfully.

"Shimukun, are you okay? After a while, the instructor will take you to the bottom of the sea, so you can familiarize yourself with the water during this time! Because the oxygen tank can only insist on breathing on the bottom of the sea for three hours, this is still measured by people who understand water, and for people who don't understand water, the oxygen consumption is even worse, and the time that can be held will only be shorter! ”

"Thank you, Instructor Chu, I understand this!"

After Shimukun thanked him, he said to the students of the Department of Archaeology of Huaxia University who were floating on the water: "Follow me!" ”

He dragged Shimukun with one hand and took the lead in diving to the bottom of the sea. Instructor Chu was worried that Shi Mukun didn't understand the nature of water and struggled indiscriminately after entering the water, but felt that Shi Mukun seemed to be swimming with him all the time, but his posture was a little weird, not like he knew water.

Most of the students of the Department of Archaeology of Huaxia University, who were following Instructor Chu, laughed in their hearts when they saw Shi Mukun's appearance, of course, except for those few students who had a good impression of Shi Mukun, they were worried about him in their hearts.

At this moment, Shi Mukun was very entangled in his heart, he was familiar with water since he was a child, and the reason why he was reluctant to jump into the sea just now was because he was afraid of accidentally injuring other students.

After all, by the time he was about to jump, there were already two hundred people at the bottom, including Instructor Chu, and most importantly, he was the only one in his scattered group, and he didn't even have one to help drive out an area for him to jump off, and he didn't bother to call at the group of students below to make room for him to enter the water, so he climbed the suspension ladder to go down.

As a result, he was mistaken by Instructor Chu for not knowing how to water, and dragged himself, so that such a good student could only float beside Instructor Chu in a strange posture.

After diving with Instructor Chu for about half an hour, Shi Mukun saw an arched bridge under the seabed, and Shi Mukun had a familiar feeling when he saw this arched bridge.

Instructor Chu's figure also stopped at this time, pointed at the group of students of the Department of Archaeology of Huaxia University, pointed to the place where the arched bridge in front of him was, pointed to himself, and then pointed to the position of the sea.

Instructor Chu's meaning was very clear, the students of the Department of Archaeology of Huaxia University entered the location of the supply bridge, and he would return to the sea.

A group of students from the Department of Archaeology of Huaxia University have explained the relevant knowledge about the ancient imperial tombs, and know that there is a place called "Twenty-four Bridges", which has a special layout, and people over a certain age have no way to enter it!

"No wonder it looks so familiar, it turns out to be the Twenty-Four Bridge!"

Shi Mukun suddenly realized in his heart, isn't this the arched bridge that he entered the campus of Huaxia University when he took the entrance examination of the Department of Archaeology of Huaxia University!

"Twenty-four bridges on a moonlit night." It is a poem that circulates in the country of China, and now it seems that the twenty-four bridges are not moonlit nights, but ages, and with their unique arrangement to screen people who meet the conditions to enter it.

Shi Mukun stood beside Instructor Chu and watched a group of students from the Department of Archaeology of Huaxia University pass through the arched bridge, and he was the last to enter.

After he entered it, when he looked back at the location of Instructor Chu, he found that he couldn't see Instructor Chu at all, not only Instructor Chu couldn't see it, but even the scene of the sea area he had just passed through was completely different

"This arched bridge seems to isolate the inside and outside, and when the qualified people are screened to enter it, it also produces a spatial distortion, and the inside cannot see the real scene outside, and the outside should not be able to see the scene inside!"

"And I heard the instructor say when he was teaching, in some special dimensional spaces, there is no way for the Eye of Surveillance to penetrate! And the space where the Ancient Emperor's Mausoleum is located belongs to this special dimensional space! ”

……

Shimukun is not like other students of the archaeology department of Huaxia University, after entering here, he is in a hurry to find the mystery in the twenty-four bridges.

After entering this special space, you can see the complete view of the 24th Bridge.

A full quarter of an hour passed, and just as Shi Mukun was about to leave to explore the secret, he found that the students of the Dongfang Group and the Dark Moon Tower Group who had just been far away had surrounded his position, and he instantly had a bad premonition in his heart.
