Shock!The beginning is a land, and the crit strikes a miracle

"Why is the exam time so fast? What should I do!"

Luo Yu was taken aback, and hurriedly turned his head to look at the clock tower outside the window. The time displayed on it was 17:00.

Chapter 790 Underwater clues

Luo Yu looked at the time displayed on the system panel again, it was 14:10.

Clock tower time has been set forward!

[Examination time is up, the paper is automatically handed in, the answer rate after the test: 1%, this mission failed, do you want to read the file? 】

This sudden failure made Luo Yu and the others look at each other in blank dismay. The time for submitting papers is calculated according to the clock tower time!

For a while, everyone's face became gloomy. Looking at the uproarious students in the examination room, Luo Yu pondered for a while and chose to read the file.

With a flash of light in front of his eyes, Luo Yu and his friends returned to the empty Yucai Building.

The time went back to nine o'clock the night before.

Na Keer stomped her feet and said, "Damn it, there is someone in the clock tower, let's kill him!"

"Optimus Prime!"

Luo Yu agreed, Optimus Prime appeared in the air and flew towards the clock tower, but was blocked by an invisible light curtain just as he approached.

[Hint: All items cannot be close to the clock tower]

"what?"

Everyone was stunned, not surprised by the air wall, but reminded that everything should not be close, including school students and teachers.

Fang Yumeng hesitated: "The first two exams were normal, and no one approached, why did the big clock suddenly break down?"

"This dungeon is too difficult." Anna sighed softly: "There was no sign before the failure. We all paid hundreds of thousands of file reading fees. Which idiot designed this dungeon?"

"Honey, do you know why dungeons are so difficult?"

"This...hahaha, maybe it's already difficult."

Luo Yu laughed twice, and said seriously: "Go back to the room first and then talk."

Elena said with some emotion on her face: "Are you still eating hot pot like yesterday?"

Alice chuckled: "You can try different flavors this time."

In the middle of the night, everything is silent.

Anna and the others were all asleep, while Luo Yu and Fang Yumeng left the dormitory together and came under the bell tower of the playground.

After the two of them investigated, they found that they could not enter the bell tower from any angle, and there was nothing special nearby. Fang Yumeng hesitated and said, "Husband, should we forcefully bombard the air wall?"

"It should be useless."

Luo Yu patted the transparent wall in front of him, and pondered: "This time the copy is different from what we usually experience, there must be some dark lines."

"I noticed that the key people in the previous examination room repeatedly mentioned the word principal, and the key to unlocking the bell tower lies with the principal."

"Principal... You said that, I also remembered, everyone seems to say that he hasn't been to school for a long time..."

Fang Yumeng was thinking while talking, suddenly understood something, and suddenly said: "Understood, the key to this level is to find the principal, and no one in the school knows where the principal is, maybe he was kidnapped by some BOSS !"

"The location must still be within the school. What we have to do is to collect clues about this as soon as possible."

Luo Yu smiled lightly and said: "This is also a way of thinking, how about it, tomorrow we will divide into two groups, you and Anna will ask the staff in the school to find clues, let me see if there are other possibilities."

"it is good!"

After the two discussed, they just waited for the sun to go up the mountain.

In the early morning, everyone started to act early in the morning, while Luo Yu wandered alone in the campus looking for clues.

He always felt that it was not that simple. The air wall covering the clock tower was very clear. No creature could enter the clock tower. So how did the other party adjust the time?

"Where is the secret?"

Walking slowly along the sparkling creek, Luo Yu's gaze fell into the water inadvertently.

The stream is clear, and occasionally groups of small fish swim happily in the water. With the swimming of the small fish, the stream has layers of ripples. Under the refraction of the sun, it looks like circles of ribbons. Lightly diffused and quite beautiful.

"Ribbons?"

"Will the creek reflect the sun, will it be colorful?"

There was a strange look in Luo Yu's eyes, he stepped forward a few steps, and squatted by the stream under the shade of the greenery to observe carefully.

Behind him, a few girls from the high school group followed from a distance. They all blushed a little, as if they wanted to come up and talk but dared not.

Luo Yu had noticed them before, not only these girls, but also the boys in the high school group would secretly look at Anna and the others with blushing faces. After all, they were too handsome, and everyone was used to it.

"The high school group has the largest number of people and seems to be the most emotional."

Luo Yu gave them a definition and then focused all his attention on the creek.

After observing for a while, he found something unusual.

The rippling ribbons are not simply reflecting sunlight, but because there are extremely fast colored pebbles at the bottom of the water. These stones make the water surface so beautiful under the reflection of sunlight.

Stretching his hand into the water, Luo Yu wanted to take a piece to have a look, but he was slightly taken aback when he held the pebble.

With his strength, he couldn't lift it!

"This……"

He strengthened his arm strength again, but no matter how hard he tried, the pebble seemed to be born at the bottom of the water and remained motionless.

Luo Yu has the power of 9999, this situation makes him happy instead of surprised, maybe the clue is here.

He took out the multicolored spear from his hand, and the tip of the spear accurately pierced into the cobblestone.

"Ding!"

With a crisp sound, the multicolored spear was directly bounced back, and the pebbles were indestructible!

"There is such a thing!"

The multicolored spear struck again, but the cobblestone beside it shattered, but it was incredible that the shattered cobblestone quickly returned to its original shape under the impact of the water flow.
