After binding the system, I became a national mystery person

Li Mengqi tried to lift the lid of the treasure chest with her hands, but couldn't lift it up.

"Sister Su, this doesn't require a key, does it?"

Li Mengqi's words stunned Su Jinru and Lin Yanjun. They had not thought of this before.

Su Jinru frowned and carefully recalled the clues she had obtained before, but there was no hint about the key.

"Did we miss something?" she thought to herself.

Lin Yanjun walked around the treasure chest, carefully observing every detail.

"Look, there seems to be a groove here." He suddenly pointed to the side of the treasure chest and said.

Upon hearing this, Su Jinru and Li Mengqi both came over.

I saw that there was indeed an irregular groove on one side of the treasure chest, which looked like it was used to place something.

"What could this be?" Li Mengqi asked puzzledly.

"This might be the keyhole, but what could the key be?" Su Jinru pondered.

The three of them began to search around the place for the key, and after their hard work, they found it.

"At this?!"

Li Mengqi saw a set of mathematical-like symbols about four or five meters away from the treasure chest.

"These symbols look so familiar! Could this be related to the treasure chest key?"

Li Mengqi's words attracted Lin Yanjun and Su Jinru to come over. They stared at the symbols on the ground together, trying to find the secret.

“Isn’t this just a mathematical formula?”

Su Jinru recognized these symbols at a glance. She has always been good at mathematics and is very familiar with these formulas.

"But what do these formulas have to do with the treasure chest?" Lin Yanjun asked doubtfully.

Su Jinru lowered her head in thought for a moment, then suddenly her eyes lit up: "I know! These formulas may represent a combination method. We need to arrange them according to a certain order or pattern to find the shape or position of the key!"

"I don't understand. My math grades have always been bad. After college, I gave all my math knowledge back to my teachers."

Li Mengqi scratched his head and looked at Su Jinru with confusion.

"Sister Su, I don't understand it either. Math is something that people who don't understand really don't understand. I am one of those people who doesn't understand it."

Although Lin Yanjun's math grades are better than Li Mengqi's, he was still confused when faced with such complex mathematical formulas.

"It doesn't matter, let me try."

Su Jinru picked up a branch and began to study the formula on the ground carefully.

Time passed minute by minute, and Su Jinru concentrated on studying the mathematical formulas, as if the whole world had stopped.

Li Mengqi and Lin Yanjun were waiting anxiously on the side. Although they could not help, they were unwilling to leave Su Jinru's side.

After more than half an hour, Su Jinru smiled.

"I made it, look!"

She pointed to the ground and used the branches to rearrange the mathematical formulas, forming a unique pattern.

"This pattern should be the shape of the key to open the treasure chest."

Su Jinru explained, “We needed to find something around us that matched this pattern.”

Upon hearing this, Li Mengqi and Lin Yanjun immediately began to search around.

They searched every inch of land carefully, leaving no possible corner untouched.

Finally, on a huge rock not far from the treasure chest, they found a groove similar to the pattern drawn by Su Jinru.

The shape and size of this groove are consistent with the key shape inferred by Su Jinru.

"Found it!" Li Mengqi shouted excitedly, and she immediately ran back to tell Su Jinru.

Upon hearing this, Su Jinru immediately ran over.

She observed the groove carefully, and after confirming that it was correct, she aligned the lock on the treasure chest with the groove.

With a "click", the lock of the treasure chest was finally opened.

Su Jinru, Li Mengqi and Lin Yanjun all smiled excitedly, they finally found the treasure!

There were some food and a piece of paper in the treasure chest.

Su Jinru carefully unfolded the paper, and on it was written a line of words: "Congratulations to everyone for completing the task. The specific rewards will be announced by the director."

“I don’t know what the specific reward is?”

Li Mengqi stared at the paper curiously, her anticipation for the reward rising sharply.

Lin Yanjun smiled and shook his head: "No matter what the reward is, the experience we have along the way is the most valuable asset."

Su Jinru nodded in agreement. She folded the paper and put it in her backpack, then looked down at the food in the treasure chest.

"It seems the production team knew we were hungry and specially prepared these foods for us."

She said with a smile, then took out some food and shared it with Li Mengqi and Lin Yanjun.

The three of them sat next to the treasure chest, enjoying the hard-earned food, their hearts filled with satisfaction.

Soon, a message came from the radio: "Congratulations to Su Wan, Li Mengqi, and Lin Yanjun for successfully finding the treasure."

"Sun Hao, Su Wan and the others are so powerful? They found the treasure so quickly?" Zhao Lei couldn't help but be surprised when he heard the broadcast.

Sun Hao also frowned. He didn't expect Su Jinru and the others to be so quick.

"But we can't fall too far behind."

Sun Hao pulled himself together and said to Zhao Lei, "We must quickly find the final mission point and our treasure."

The two continued to follow the route on the map, and after a difficult journey, they finally arrived at an open space.

There was an ancient stone tablet standing in the open space, with some strange symbols and patterns engraved on it.

"Is this the final mission point?" Zhao Lei asked doubtfully.

Sun Hao nodded and carefully observed the symbols and patterns on the stone tablet, trying to find clues.

After studying for a while, Sun Hao's eyes suddenly lit up: "I understand! These symbols and patterns are actually a puzzle. We need to solve it to get the final reward."

Zhao Lei came over immediately after hearing this: "Then let's solve it quickly. I don't want to lose to Su Wan and the others for too long."

The two began to study the puzzle on the stone tablet seriously. As time passed, sweat gradually seeped out of their foreheads.

Finally, after many attempts and failures, they succeeded in solving the puzzle.

The stone tablet slowly moved, revealing a hidden cave entrance.

"Great, we found it!" Zhao Lei shouted excitedly.

Sun Hao also smiled and patted Zhao Lei on the shoulder: "Let's go in and take a look."

The two walked into the cave carefully and saw an exquisite treasure chest inside.

The treasure chest was inlaid with various gems, sparkling with dazzling light, and looked even more precious than the treasure chest found by Su Jinru and the others.

"Is this the ultimate treasure?" Zhao Lei asked in surprise.
