The Emperor's Favorite: The Useless and Crazy Concubine Who Conquers the World

She didn't know whether the man in black robe could be trusted, nor did she know what his purpose was.

"Don't worry, I have no ill will towards you." As if seeing Lan Yunyan's hesitation, the man in black robe said slowly.

"Okay, I promise you. But you must tell me the secret of the treasure." Lan Yunyan said.

The black-robed man smiled and said, "Of course. Do you know? This treasure was left behind by an immortal from the upper continent. It contains endless wealth and mysterious power.

However, finding the treasure is not easy and requires solving a series of puzzles and mechanisms. I have found most of the treasure, but the last part is protected by a powerful formation that I cannot decipher.

I heard that you are a woman with great martial arts skills and a keen mind, so I hope you can help me break the formation and find the treasure."

Lan Yunyan was shocked when she heard the black-robed man's words. She had never expected this treasure to be so mysterious and actually related to the immortals of the upper world.

"Okay, I promise you. But how are we going to cooperate?" Lan Yunyan asked.

The black-robed man pulled out a map from his bosom and handed it to Lan Yunyan, saying, "This is the treasure map. It marks the location of the last part of the treasure and the method to break the formation. Let's follow the instructions on the map and go to the treasure together, break the formation, and find the treasure."

Lan Yunyan took the map and looked at it carefully. She found that the markings on the map were very complicated and she needed some time to study them.

"Okay, we'll set off tomorrow." Lan Yunyan said.

The man in black robe nodded and said, "Okay, I'll wait for you here tomorrow."

After saying this, the black-robed man turned and disappeared into the night. Lan Yunyan returned to her residence and began to study the markings on the map and the method to break the formation.

She knew that this treasure hunt would be very dangerous and she had to be fully prepared.

The next morning, Lan Yunyan got up early, packed her luggage, and prepared to leave. She arrived at Shilipu outside the town and saw the man in black robes waiting for her there.

"Are you ready?" asked the man in black robe.

Lan Yunyan nodded and said, "I'm ready, let's go."

So, they set out towards the treasure according to the instructions on the map. Along the way, they passed through dense forests, steep mountains and turbulent rivers, and finally came to a valley.

There is a mysterious atmosphere in the valley, and the surrounding mountains are towering into the clouds, like a natural barrier.

"According to the instructions on the map, the treasure is in this valley." said the man in black robe.

Lan Yunyan nodded. She looked around and found a huge stone platform in the valley, which was engraved with various strange symbols and patterns.

"This should be the formation protecting the treasure." Lan Yunyan said.

She walked over to the stone platform and carefully examined the symbols and patterns on it. She found them to be extremely complex, seemingly ancient writing and patterns. She tried to decipher their meaning, but she had no clue.

"Can you understand these symbols and patterns?" asked the man in black robe.

Lan Yunyan shook her head and said, "I don't understand. These symbols and patterns are too complicated. We need to find some clues to crack this formation."

So, the two began to search for clues in the valley. They carefully observed every corner of the valley, not missing any possible clues.

Finally, they found a cave on one side of the valley. The cave was filled with a mysterious atmosphere, as if it was hiding some secrets.

"Let's go in and take a look." Lan Yunyan said.

The two walked into the cave and found it filled with all kinds of strange stones and symbols. Lan Yunyan carefully observed these stones and symbols, and suddenly, she found a symbol engraved on one of the stones that was exactly the same as the one on the stone platform.

"This is a clue!" Lan Yunyan said excitedly.

She studied the stone carefully and found that the symbol on the stone seemed to be a clue. Based on this clue, she found the corresponding symbols on the stone platform and pressed them in a certain order.

As Lan Yunyan manipulated the stone platform, a ray of light suddenly emanated, and the formation began to slowly rotate. Lan Yunyan and the black-robed figure nervously watched the changes in the formation, their hearts filled with anticipation.

After the formation rotated for a while, it suddenly stopped and a hole appeared on the stone platform.

"We succeeded!" Lan Yunyan said excitedly.

She and the black-robed man walked into the cave and found a spacious secret room inside. The secret room was filled with gold, silver, treasures, various precious elixirs and medicinal herbs, emitting a dazzling light.

"This is the treasure!" the man in black robe said excitedly.

He walked over to the treasure and began to pick out items that he liked.

Since the man in black robe was not an alchemist, he left a large amount of medicinal herbs to Lan Yunyan.

Lan Yunyan stood aside, watching her surroundings warily. She knew that the appearance of treasures often brought danger, so she had to remain vigilant.

Just as the black-robed man was immersed in the joy of the treasure, suddenly, a strange sound came from the secret room. Lan Yunyan and the black-robed man immediately became alert. They looked around but found no signs of anything unusual.

"Be careful, it might be dangerous." Lan Yunyan said.

As soon as she finished speaking, many small holes suddenly appeared on the walls of the secret room, and countless arrows shot out from them. Lan Yunyan and the black-robed man quickly dodged, and the arrows flew past their bodies and pinned them to the ground.

"This is a mechanism!" Lan Yunyan shouted.

She and the black-robed man began searching for the control device of the mechanism in the secret room, but found nothing. Arrows continued to shoot from the walls, and Lan Yunyan and the black-robed man gradually fell into trouble.

Just when they were feeling desperate, Lan Yunyan suddenly discovered a strange symbol. This symbol was exactly the same as the one she had seen in the cave, and she immediately thought of a way to crack the mechanism.
