One day, Lan Xi was giving a lecture, and there were many college students and former students sitting in the audience, and when they heard that Professor Liu was going to give a lecture, they all rushed to the school to listen to the teacher's teachings.

When talking about how to use cell regeneration technology to treat patients, the discussion on and off the stage was very active, and Lanxi was happy to answer the children's questions.

Suddenly, the principal hurriedly walked into the auditorium, and the lecture in the auditorium stopped abruptly, and everyone looked at the principal curiously, what made him so anxious. Lan Xi saw the principal walking straight towards him, as if he was still holding a piece of paper in his hand, for some reason, Lan Xi seemed to have a premonition in his heart, and an indescribable sadness suddenly hit his heart.

Unfolding the piece of paper, Lan Xi saw a few big words: Obituary: Comrade Jiang Tianjian passed away on May 8, 1982.

The piece of paper slipped silently, Lan Xi stumbled and almost fell, and the principal hurriedly stepped forward to support Lan Xi.

Lan Xi sat down on the chair, and the principal signaled that today's class was canceled for some reason, and asked everyone to wait for the next notice, but many students were very worried when they saw Professor Liu's situation and wanted to stay with the professor, but they were still driven away by the principal.

There were only two people left in the auditorium, Lan Xi and the principal.

A letter was handed to Lan Xi again, the same envelope, the same stationery! Lan Xi opened with a shudder.

Dear Sister Lanxi,

I'm afraid this is really the last time I'll call you that! I know that you and I have no fate in this life, and I know that the person who lives in your heart is not me, but how I wish I could be by your side. If I really don't have a chance in this life, I don't dare to hope for the next life, I just want to become a butterfly and always be by your side!

Also, Sister Lanxi, can I trouble you with something? I hope you can scatter my ashes into the sea yourself, because more than forty days on the sea are the happiest time of my life, and I hope to be immersed in happiness forever!

Your godsend

Lan Xi's hands kept trembling, the letter slipped again, and the tears had already flooded.

God, you, how stupid!

On the same day, Lan Xi set off to the place where Jiang Tianjian had worked, and completed Jiang Tianjian's funeral accompanied by the leaders of the Scientific Research Bureau.

Holding Jiang Tianjian's ashes, Lan Xi came to Haishi and took a ship to the sea. Open the urn, grab a handful of ashes, scatter them into the sea, and watch the ashes be blown away by the wind little by little.

God, I owe you in this life!

After scattering the ashes, Lan Xi still stood on the beach and didn't want to return, so he sat there until sunset. Seeing that many staff members were working hard because of their willfulness, Lan Xi felt sorry for it, so he was ready to get up and go back.

At this moment, a colorful butterfly suddenly landed on the back of Lan Xi's hand, no matter what Lan Xi did, the colorful butterfly flew around Lan Xi, unwilling to leave, very attached.

Lan Xi's heart moved, God-given, is it you? Since you don't want to leave me, then stay with me! Hearing Lan Xi's murmuring, the butterfly flew more happily, flying up and down around Lan Xi, and even Lan Xi felt its happiness.

Since then, Lan Xi has one more colorful butterfly by his side, this phenomenon has been praised by many people, and Lan Xi is affectionately called "Butterfly Professor", and Lan Xi's reputation is even higher!

Under Lan Xi's care, Father Bosheng lived to be ninety-five years old, and Lan Xi also lived to be one hundred and five years old in this world, not only enjoying world reputation, but also replenishing the experimental equipment and daily necessities in his own space. What's even more amazing is that the butterfly has always been with Lan Xi, it is said that a butterfly's lifespan should not be so long, but that's what happened.

Lanxi has donated all his research results to the country, and has cultivated a large number of talents without selfishness.

It's time to leave, send the colorful butterfly into the space, and Lan Xi will come out of this body that has reached the end of its life.

In the air, Lan Xi saw a face that she had seen for decades, and Lan Xi asked her with a smile: "Can you get your wish?" ”

The other party replied: "Yes!" As he spoke, something shiny floated towards Lan Xi's spirit.

The other party dissipated in this world with a smile!
