I used space to carry a lot of supplies to escape famine in ancient times

From then on, they lived a peaceful and happy life, and their story became an eternal legend among people.

However, the gears of fate did not stop turning. On a quiet night, Gu Qianning and Chu Mohan were awakened from their sleep by a mysterious light. The light seemed to be calling them, leading them to an unknown journey.

When they followed the light to an ancient cave, they had an inexplicable premonition in their hearts. This cave was hidden in the mountains and was filled with a mysterious atmosphere.

The two walked into the cave without hesitation. The cave was filled with damp mist, and strange runes flickered on the walls. They moved forward cautiously, with every step full of vigilance.

As they walked, they came to a spacious hall. In the center of the hall was the scene where they had fought before, and the figures of the time guardians they had defeated seemed to be frozen there.

"What's going on?" Gu Qianning asked puzzledly.

Chu Mohan frowned, thought for a moment and said, "Perhaps this is another test given to us by fate."

At this moment, an ancient and deep voice sounded in the hall: "Do you think that you can easily obtain the Key of Time by defeating the Guardian? You are too naive!"

Gu Qianning and Chu Mohan looked around, trying to find the source of the sound.

"The Time Key is hidden in a series of complex puzzles. Only after you solve these puzzles will you be qualified to own it." The voice continued.

As the sound disappeared, mysterious patterns and words began to emerge on the walls of the hall. These were the clues to the puzzle.

Gu Qianning and Chu Mohan approached the wall and carefully observed the puzzles. The first puzzle was an ancient map with some strange symbols and routes marked on it.

Chu Mohan thought for a moment and said, "This seems to be guiding us to find a specific location."

Gu Qianning nodded in agreement, and the two began to search the cave according to the clues on the map. They passed through narrow passages and avoided various hidden traps.

Finally, they came to a hidden stone chamber. In the chamber was a huge stone tablet with densely engraved words.

"This should be the second puzzle." Gu Qianning said.

They carefully studied the text on the stone tablet and found that it was a record of ancient history, but it also contained key codes.

After some hard thinking, Gu Qianning finally discovered the pattern in the text and successfully cracked the code.

As the code was cracked, the floor of the stone chamber began to slowly sink, revealing a passage leading to a deeper level.

They continued along the passage and came to a foggy room. The walls of the room were flickering with faint lights, forming complex mathematical formulas.

Chu Mohan looked at these formulas with a frown on his face: "This is a test of our logical thinking ability."

Gu Qianning quickly took out a pen and paper from the space and began to calculate. After a long period of effort, they finally solved all the formulas, and the fog gradually dissipated.

The puzzles become more and more complicated. There are mechanisms that need to be solved by the rhythm of music, codes that need to be deduced based on the arrangement of constellations, and puzzles that require knowledge of ancient characters to understand.

In the process of solving the puzzle, Gu Qianning and Chu Mohan encountered many difficulties. Sometimes, they had to start over because of a small mistake; sometimes, they fell into long-term thinking and almost felt desperate.

But they never gave up and encouraged and supported each other.

While solving a puzzle about ancient philosophy, they argued endlessly and each had different opinions.

"I think we should think about it from this perspective." Gu Qianning said.

Chu Mohan shook his head: "No, I think we should start from another aspect."

After intense discussion, they finally found a perfect combination point and successfully solved the puzzle.

As puzzles were solved one by one, they got closer and closer to the Time Key.

When they solved the last puzzle, a treasure chest shining with mysterious light appeared in front of them.

Gu Qianning and Chu Mohan looked at the treasure chest nervously, their hearts full of anticipation.

Chu Mohan slowly opened the treasure chest. However, there was no time key inside, only an ancient parchment.

There was a line of words written on the parchment: "The real key lies in your heart."

The two looked at each other and fell into deep thought.

"In our hearts? What does this mean?" Gu Qianning said puzzledly.

Chu Mohan closed his eyes, thinking back to their experiences along the way, and suddenly it dawned on him: "Qian Ning, I understand. The Time Key represents not only a kind of power, but also our courage, wisdom and persistence when facing difficulties. These qualities are the real keys."

After hearing this, Gu Qianning's eyes flashed with enlightenment: "So that's how it is."

At this moment, a strong light emanated from the treasure chest, and in the light, the Time Key slowly emerged.

They finally got the Key of Time.

However, they were not overwhelmed by joy at this time.

"This key contains enormous power, we must use it with caution." Gu Qianning said.

Chu Mohan nodded: "Yes, we must use it to do the right thing."

With the time key, they left the cave, but they knew that there were more challenges and responsibilities waiting for them in the future.

Back home, they began to think about how to use the power of the Time Key.

"Maybe we can use it to help those who have suffered misfortune in history." Gu Qianning suggested.

Chu Mohan agreed: "But we must be careful not to change the general direction of history, so as not to cause unpredictable consequences."

So they started a new adventure. Using the power of the time key, they quietly helped people in trouble and changed some small but important historical events.

During one operation, they discovered that a village was about to suffer a disaster. Using the time key, they went back to the past and warned the villagers in advance, allowing them to avoid the disaster.

In another adventure, they helped a wrongly accused historical figure clear his name and restore his reputation.

However, their actions are not always smooth sailing. Sometimes, their interventions will trigger some unexpected chain reactions, which require them to spend more energy to solve.

Once, when they were changing a historical event, they accidentally caused a small space-time fluctuation, which almost caused serious consequences.

"It seems we have to be more cautious." Gu Qianning said with lingering fear.

Chu Mohan comforted her: "Don't worry, we will become more and more proficient."

As time went by, Gu Qianning and Chu Mohan gradually mastered the skills of using the Time Key, and their actions became more precise and effective.

But they always remain in awe, knowing that the power of time is extremely strong and any carelessness can bring disaster.

On a sunny day, Gu Qianning and Chu Mohan sat in the courtyard, reviewing their adventures.

"This period of time has been full of challenges and surprises." Gu Qianning said with emotion.

Chu Mohan smiled and held her hand: "But as long as we are together, we can overcome any difficulties."

At this moment, a strange light suddenly appeared in the sky.

"What is this?" Gu Qianning said in surprise.

Chu Mohan stood up and looked at the sky vigilantly: "I don't know, but I feel that there are new adventures waiting for us."
