"Of course it's okay to take you and it away from here, but Grandpa Cane can't take you out of this world. Is there going to be another explosion?" Marvin asked.

Dudu scratched his head and said honestly: "I don't know about this... unless you ask the wizard."

Marvin said: "It seems like this is the only way to go. Then let's go."

Dudu asked: "Where to go?"

"Go to the Great Falls to find the wizard."

Dudu shook his head: "I can't go."

"Why?"

"When I get there, my memory will disappear forever. Maybe, like the birds in the lake and the fish flying in the sky, I will forget that I am alone."

People who want to leave this world cannot go underground, and hamsters who want to leave this world cannot come above ground.

Marvin didn't know how to solve this problem, but what he needed to do now was to go underground and talk to the wizard first.

I have been to the waterfall and back many times, and now I am very familiar with it.

Even the black hamster who punted the boat was much more polite to Marvin, and was no longer as cold as before.

In the wizard's hall, the wizard was surprised when he heard that Marvin had completed the second task.

According to his guess, this task would definitely not be completed in less than ten days and a half.

When the wizard listened to Marvin's explanation of how he completed the task, he praised Marvin and said, "Marvin, you are much smarter than I thought."

Marvin smiled proudly, and then quietly waited for the wizard to give him the third task.

But after waiting for a long time, the wizard didn't speak.

Finally, Marvin couldn't help but ask: "Wizard, where is the third mission?"

"What third task?" the wizard answered.

"Didn't you say that after completing three tasks, you would give me the memory magic water? I have already completed two tasks."

"Oh." The wizard touched the back of his head, "Wait a moment and let me drink some water."

Then the wizard took out two bottles from under the seat. One was copper and the other was silver. After looking at it for a long time, he whispered: "Which bottle did I drink just now?"

After thinking for a long time, he finally put down the copper bottle, opened the lid of the silver bottle and took a sip. He closed his eyes and rested for a few minutes before opening his eyes and talking to the black hamster next to him.

After talking for a long time, he said to Marvin: "I remembered it. You are asking about the third task, right?"

Marvin nodded and massaged his neck with his hands. It was really hard to keep looking up at the ceiling like this.

"The third task is... No, no, I drank from the wrong bottle." The wizard picked up the copper bottle again, thought about it carefully, finally nodded, opened the bottle cap, and took a sip.

He closed his eyes and rested for a while, then opened his eyes and said to Marvin: "Have you met the man by the river?"

"Yes." Marvin answered.

The wizard said: "That's good. Then I don't need to explain anymore. Don't you want to go to Memory Star? I can take you there."

"How to get there?"

The wizard said: "Can't your walking stick go anywhere in the world? I'll tell you a place, and you just let the walking stick take us there."

Marvin asked cautiously: "Is there going to be an explosion?"

"Explosion? Of course there won't be one. Well... I'm not completely sure. The last explosion was caused by accident. Don't worry, it won't happen again this time."
