"Get up, people who don't want to be slaves. Let's build our new Great Wall with our flesh and blood. The Chinese nation has reached its most dangerous time, and everyone is forced to make a final roar. Get up, get up, get up... We are all united.

, advance under the enemy's fire, advance under the enemy's fire, advance, advance, advance."

Madoudou and Zhiguoguo sang very seriously, and both Madoudou and Zhiguoguo shed tears.

"Sister, it's time for us to say goodbye to Mumen. Through this trip, we have learned about the history and culture of the motherland. We must cherish our present more, study hard to repay the motherland, and be a useful person to the motherland when we grow up.

."

Madoudou wiped the tears from his eyes and told Zhi Guoguo about his decision.

He and Zhi Guoguo had been out playing for too long, and it was time to let Mumen take them home.

"Open Sesame, please take us home, okay?"

Mumen, who never spoke, made a sound this time.

"Aren't you going to continue your trip?"

Madoudou held Zhiguoguo's hand and bent towards the wooden door.

"No, we've been out for too long. Dad Ma and Mom Zhi should worry about us. You'd better send us home! My sister and I don't want to miss the handwritten newspaper competition celebrating the 100th anniversary of the Party."

Mumen sighed with some regret, shook his body and compromised.

"Well, since you are homesick, I will send you back. In the future, if you still want to time travel, remember to call me."

Madoudou and Zhiguoguo, brother and sister, nodded one after another and agreed to Mumen.

"Okay. When we want to travel in time and space, we will definitely call you."

After saying that, Mumen asked Madoudou and Zhiguoguo to close their eyes. After a while, Madoudou and Zhiguoguo returned to their modern home through the torrent of time and space.

Dad Ma and Mom Zhi were shocked when they saw Madou Doudou and Zhi Guoguo falling from the sky.

"Madoudou, Zhiguoguo... what are you..."

Madoudou and Zhi Guoguo, brothers and sisters, opened their eyes and saw that it was Mother Zhi. They rushed over and hugged Mother Zhi tightly.

"Mom Zhi, we miss you so much!"

When Dad Ma saw Madou Doudou and Zhi Guoguo, whom he had not seen for a long time, they were back, he also went up to greet them and put Mother Zhi, Madou Dou and Zhi Guoguo in his arms.

"My little darlings, you are finally home. Where have you been?"

Madou Doudou told Father Ma and Mother Zhi about the adventures he and Zhi Guoguo had after finding a wooden door in the desert. Father Ma and Mother Zhi found it incredible after hearing this.

Mother Zhi stretched out her hand to explore the foreheads of Madou Doudou and Zhi Guoguo, "You...are you telling the truth?"

Madoudou knew that telling people what happened would be weird, but he didn't want to hide it from Father Ma and Mother Zhi.

"Yes, Mother Zhi. Look, this is the wooden door. Just shout to the wooden door to open sesame..."

Madoudou didn't finish the remaining three words of change.

Because Mumen once said, "Open sesame, change, change, change" will unlock Mumen's ability to travel through time and space.

Mother Zhi took Madoudou from the wooden door in the middle and looked at it carefully. Seeing that it was no different from ordinary handicrafts, she handed the wooden door to Father Ma again.

"Dad Ma, look at this wooden door? Is this... really like Doudou said, can you travel through time and space?"

Dad Ma pretended to hold the wooden door in his hand, he looked at Madou Doudou and blinked.

"How about we try now and open sesame..."
