That mulberry tree is very big. The tree is full of mulberry fruits, red or purple, making people salivate. Vaguely visible red silkworms are lying on the mulberry leaves and nibbling.

The tree cannot be seen in size if there is no contrast in the painting, so the painter painted many children under the tree, and seven or eight people held hands to surround the tree before reluctantly circle the tree. Two courageous children climbed to the tree to pick mulberries, and they stunned a huge crow on the top of the tree.

Looking at this painting, Bishenghua suddenly remembered the vague old photo that she picked up under the willow tree that day.

Mei Yiqiu did not say where this set of pictures came from, nor did he ask. She is a cool person, she doesn't like to ask questions. If she can say, the professor will tell her, and if the professor doesn't say it, there is a reason why he doesn't say it.

For the life flower, this set of pictures is a good choice, not an icing on the cake for the current project. She has been suffering from not knowing the exact appearance of the mulberry garden at that time, nor can she find any historical information about the mulberry garden. Except for the short records in the county chronicles and the old willow tree in Liuying Lane, no one can prove the existence of this place. Before, let alone tell the life flower how to restore the mulberry garden.

Bishenghua looked through it several times, and through comparison, it was determined that the place where the willow tree is now is the location of the giant mulberry tree that year. The mulberry garden was divided into two parts, the mulberry tree was in the middle of the front garden, and the willow tree was by the lake in the back garden. This is consistent with the ancient legend she knows.

"Professor, thank you so much." Bi Shenghua sincerely thanked you.

Mei Yiqiu said, "You don't have to thank me. I came here in the rain so late, and I won't give you anything in vain. I want you to do me a favor."

I spent a lifetime stunned and said, "Professor, please tell me, as long as I can do it."

Mei Yiqiu said, “Don’t rush to agree. This is simple to say, but not easy. Once you agree to do it, it may take a lifetime to wait and persist, just like something you are insisting on now. The same. And if things really develop to the most unfortunate step as I expected, then you need to take on the responsibilities that shouldn’t belong to you, and you may be infamy and notorious because of this, and spend your time in self-doubt and denial. For the rest of your life. You need very firm belief and fearless courage to face the consequences of this matter for you and the world. Of course, I will always stand in front of you and bear everything you should bear before you ."

Bi Sheng Hua didn't understand it very well, and looked at the professor in confusion and said, "Can you make it simpler, for example, what do you want me to do, and what is the worst consequence?"

The professor took a deep breath, then took out a car key-like thing from his pocket with a red button on it.

"What I want you to do is press this button at the appropriate time."

Bi Shenghua took it and took a look. It was indeed like a car key. There was even a car logo on it. It was a triangle with two vertices connected with a thin line passing through it.

"Just press it?" She made a press with her thumb.

"Yes, exactly."

"What are the consequences?"

"It's still not certain. The best result is that nothing happened; the worst result..." The professor exhaled a thick white smoke, blocking his wrinkled face, "The worst result is that humans return By the 1960s."

"Time travel?"

Bi Shenghua knew that this professor was a famous scientist, but couldn't believe that this little key in his hand was a space-time machine. Even if it is true, what's wrong with being able to travel through time and space?

"No! It's not time travel." The professor's face is still hidden behind the continuous spray of smoke. "In 1960, the world's population exceeded 3 billion and reached 4 billion in 1974. The population in the 1960s was almost half of what it is today. If you press this button, the worst result will be the loss of half of the population on the earth, and human technology and civilization will also return to the level of the middle of the last century. That’s why I said that mankind will return to the 1960s. ."

Bi Sheng Hua was taken aback, and quickly removed her finger from the red button.

"Don't worry, it has insurance on its side." Mei Yiqiu said, "You must turn on the insurance before you can trigger the switch."

"Professor..." Bi Shenghua wanted to ask what the **** is this, nuclear bomb? Genetic weapons? But she felt impossible.

The professor seemed to see her thoughts, and laughed a few times and said: "Don't worry, it's not what you think, I am not frantic to the point of being anti-human. On the contrary, this is saving mankind, which may not necessarily be successful, but I will do my best."

I don't know if it's because of smoking too much, laughing too loudly, or bad health, Mei Yiqiu coughed violently, her silver hair trembling all over her head.

"Why me?" Bi Shenghua asked.

"Two reasons...cough cough cough cough..." The professor coughed a few more times before slowly calming down, "I must give it to the person I trust the most. Originally there was a person who was very suitable, but he is not here now. . I, like you, have been waiting for him to come back. But my time is running out, I must find someone else. He is the person I trust the most, and you are the person he trusts the most, so I thought about it You. This is the first reason. Of course, this is not enough to make me determined to give you such an important thing."

Spend his life nodding to express his understanding, "So, what about the second reason?"

"The second reason, cough, cough..." The professor couldn't help coughing, but he was still reluctant to remove the pipe from his mouth. "The second reason is...cough cough...I saw you just now. At that time, I saw it from you-hope!"

"hope?"

"That's right~lightnovelpub.net~ Hope! This is the most important thing. I hope that people can be courageous and support people with firm beliefs, so that people can survive in the harshest environment, no matter dirty or painful. , Shame, sadness, loneliness... Hope is also the only motivation for us to survive in the vast and dark universe!"

Bi Shenghua didn't quite understand these things, but she still decided to accept Mei Yiqi's commission. She believed the old man with silver hair, just as she believed the wood in the chicken coop.

"I promise you." She looked at the key in her hand and said, "Does this thing have a name?"

"Name?" Mei Yiqiu was taken aback, "Ah, it's time to choose a name, let's call it the'Key of Dreamland'."

"The Key of Dreamland..." Lifelong Hua muttered several times, "So, when should I press this button?"

"At the right time," Mei Yiqiu said.

"At the right time?" Huanhua was puzzled.

"You will know then. This is the sword of Damocles. As a sword bearer, when it needs to be cut off, you will surely get the prompt you deserve. Follow your heart to do it. Bar!"

The professor stood up as he said, "Today is a worthwhile trip, it's too late, I should go too."

The flower of a lifetime sent him out.

When passing by the bird shelf, the professor sniffed and walked over like a hound who smelled the smell, pinched a piece of sauced elbow meat from the bird food box, smelled it, and then stuffed it into his mouth, chewing and saying: " Hmm, it tastes really good!"

Then suddenly asked: "Did you buy a space box?"

Bi Shenghua said in surprise: "Yes, what's the matter?"

The professor took another piece of elbow meat in sauce, and while walking out, said: "Lock it in the cabinet, remember, never use it."
