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

When the light enveloped them, Gu Qianning and Chu Mohan hugged each other tightly, their hearts filled with firm belief. They didn't know what was waiting for them, but they were willing to face everything bravely for justice and love.

The light gradually faded, and they found themselves in a huge circular hall. The walls were inlaid with strange gems, emitting a faint light. In the center of the hall, there was a huge stone platform, on which was placed a key shining with mysterious light. That was the time key they had dreamed of.

However, just as they were about to walk towards the stone platform, a group of figures suddenly appeared around them. These figures were tall and majestic, wearing golden armor and holding shining weapons. They were the time guardians in the ruins.

"Stop! Mortals, you are not allowed to touch the key of time!" The leading guardian shouted loudly, his voice echoing in the hall, shocking everyone.

Gu Qianning and Chu Mohan looked at each other, their eyes full of determination.

"Lord Guardian, we obtain the Time Key in order to save all living beings and correct the mistakes of the past." Gu Qianning stepped forward and tried to explain.

"The order of time cannot be changed. This is the law of the universe." The guardian rejected her request mercilessly.

Chu Mohan clenched the sword in his hand, "But some mistakes, if not corrected, will bring more disasters."

The guardians heard this, roared in unison, and rushed forward instantly. A fierce battle began.

Chu Mohan flashed and rushed towards the guardian who was in the front. His sword intersected with the guardian's weapon, making a harsh sound and sparks flying. Chu Mohan felt the opponent's powerful force and his arm went numb, but he gritted his teeth and fought hard.

Gu Qianning cast a spell on the side, and rays of light flew out from her hands and attacked the guardians. But the guardians' defenses were very strong, and the rays of light only slowed down their movements slightly.

"This is not a solution. We must find their weakness!" Gu Qianning shouted loudly.

Chu Mohan observed the movements of the guardians while fighting. He found that every time the guardians launched a powerful attack, a certain part of their armor would shine more brightly.

"Attack the glowing parts on their armor!" Chu Mohan reminded Gu Qianning loudly.

Gu Qianning heard this and concentrated her strength to attack that part. As expected, the Guardian's movements became slow after being hit, and Chu Mohan took the opportunity to stab him in the gap with a sword and repel him.

Seeing this, the other guardians became even more angry and attacked more fiercely. Chu Mohan and Gu Qianning worked closely together, dodging left and right, constantly looking for opportunities to counterattack.

During the fierce battle, Chu Mohan was accidentally hit by a guardian and fell to the ground.

"Mo Han!" Gu Qianning rushed towards him anxiously.

At this moment, several guardians took the opportunity to attack. Gu Qianning didn't have time to think about it. Suddenly, a powerful force burst out from her body, forming a shield that enveloped the two of them.

"Qian Ning, you..." Chu Mohan looked at her in surprise.

"There's no time to explain. We can't give up!" Gu Qianning said gritting her teeth.

Although the shield temporarily blocked the guardian's attack, Gu Qianning's strength was rapidly consumed.

Chu Mohan stood up, anger burning in his eyes, "Don't worry, I won't let you pay in vain."

He rushed into the battle again, his sword was even more fierce. Gu Qianning also struggled to continue casting spells to assist Chu Mohan.

After a hard fight, they finally found the rhythm of the guardians and gradually gained the upper hand. They defeated the guardians one after another, but they themselves were also wounded and exhausted.

Just when they thought victory was in sight, the leading guardian suddenly emitted a powerful energy wave, causing the entire hall to tremble.

"This is the final test. If you can withstand this blow, you will get the Key of Time." The guardian's voice was solemn and serious.

Gu Qianning and Chu Mohan held hands and looked at each other, their eyes full of determination.

A powerful energy rushed towards them, and they hugged each other tightly, resisting with each other's strength and faith.

At that moment, time seemed to stand still, and every detail of their journey flashed through their minds, including the difficulties and obstacles, and the moments of mutual support.

"For justice, for love!" they shouted in unison.

A miracle happened. The powerful energy was gradually absorbed by them and turned into a warm force flowing in their bodies.

Upon seeing this, the guardians all knelt on one knee.

"You have passed the test and proved your determination and courage. The Key of Time belongs to you, but remember to use its power with caution." said the leading guardian.

Gu Qianning and Chu Mohan walked up to the stone platform and picked up the time key. At this moment, their hearts were filled with emotion and responsibility.

"We will definitely use it with caution and live up to your trust." Gu Qianning said solemnly.

With the time key, they left the ruins, but they knew that the road ahead was still long and there were more challenges waiting for them.

However, with each other's company and shared beliefs, they were fearless.

Back to the outside world, the sunlight shines on them, warm and soft.

"Finally got it." Chu Mohan looked at the key in his hand and breathed a sigh of relief.

Gu Qianning smiled, "But this is just the beginning, we have more important things to do."

They decided to find a safe place first and study how to use the Time Key to achieve their goal.

In a quiet valley, they set up a simple camp. At night, beside the campfire, Gu Qianning and Chu Mohan carefully discussed the next plan.

"According to the clues we got before, using the Time Key requires specific rituals and spells." Gu Qianning said.

Chu Mohan nodded, "But this ceremony may be risky, we must be fully prepared."

Over the next few days, they recovered from their injuries while preparing the items needed for the ceremony.

During the preparation process, they encountered some minor troubles. For example, a rare herb they needed was hard to find in the nearby mountains. But they did not give up, and after hard work, they finally found a substitute.

Finally, everything is ready.

On a full moon night, they began the ceremony.

Gu Qianning and Chu Mohan stood in an ancient magic circle, holding the time key in their hands and chanting mysterious spells.

As the spell was chanted, the Time Key began to emit a strong light and the surrounding space began to distort.

"Hold on!" Chu Mohan shouted.

Gu Qianning's forehead was covered with sweat, but she still recited the spell firmly.

Suddenly, a huge beam of light shot up into the sky, illuminating the entire valley.

When the light fades, they find themselves transported back to a crucial moment in the past.

"Success!" Gu Qianning said excitedly.

But they know that the real challenge has just begun.

In this bygone era, they moved cautiously to avoid changing the course of history while looking for opportunities to correct their mistakes.

They encountered many difficulties and dangers, sometimes they were misunderstood and hunted by people at that time, and sometimes they encountered natural disasters.

But they never gave up, and with wisdom and courage, they got closer to their goal step by step.

In a crisis, they almost exposed their identities. Fortunately, Chu Mohan was quick-witted and resolved the crisis.

"That was a close call!" Gu Qianning was already feeling scared.

Chu Mohan comforted her, "Don't be afraid, we will definitely succeed."

After a long effort, they finally found the key to correct the error.

At a critical moment, Gu Qianning and Chu Mohan acted decisively and successfully changed the course of history.

When everything was over, they activated the time key again and returned to their own era.

They discovered that the world became a better place because of their efforts.

"We did it." Chu Mohan and Gu Qianning hugged each other and cried.
