According to Yu Wei, although Sun Yuanrang dropped out of school in the past two years, his address has not changed.

Although he was promoted to a visiting professor by a certain school, he did not live in the residence prepared for him by the school. Instead, he insisted on staying in this city and studying something.

After hearing the information about Sun Yuanrang from Yu Wei, Bai Ling felt more and more that it was probably his original self who changed Sun Yuanrang's fate.

Otherwise it would be difficult to explain why he would give up a more affluent life and greater fame and instead stay in the small city of Linjiang and continue to do arduous research.

It can only be that his original self also used the grand proposition of "saving the world" to deceive Sun Yuan into believing his words, and was determined to prepare for the future!

So, what kind of surprises or... astonishments can this plan that I started two years ago bring me?

Bering was looking forward to this.

When he arrived at Sun Yuanrang's community, Bai Ling could see Sun Yuanrang's home at first sight.

It is still the same as I remember it, even the potted plants at the door are placed the same as I remember.

Just as ugly.

Bai Ling took out a key from the dry soil of the potted plant, opened Sun Yuanrang's door, and walked into the home of this senior whom he had not seen for a long time.

It was obvious that Senior Sun Yuanrang was a guy who was basically disorganized in his life just like himself. The furnishings in his house could almost be called a "disaster", not to mention the pile of unwashed dishes in the sink, the messy takeout boxes piled on one side were enough to make people frown.

Tsk, this guy, I didn’t expect that he hasn’t changed much in this world.

Didn't my original self know how to teach him how to improve his living standards? He's already a visiting professor, but he's still in such a mess.

Bai Ling remembered that Sun Yuanrang seemed to have a girlfriend. He had a very good relationship with his girlfriend, and she would usually come to his house to help him with housework.

But now it seems that his girlfriend hasn't visited him for a long time.

Could it be that Sun Yuanrang lost his beloved girlfriend in this world because of his own actions in the original world?

For some reason, Bai Ling felt guilty for no reason.

He walked across the carpet that was stained with countless footprints, ignoring the many roughly opened express boxes along the way, until he stopped at the door of Sun Yuanrang's bedroom.

The bedroom door was not closed, and Bai Ling could easily see what was going on inside.

Just like outside, Sun Yuanrang's bedroom was still very messy. Next to it was a bed piled with various measuring instruments, and next to the bed was a desk with a dim lamp on it.

At this moment, a hunched figure is bending over the desk, writing furiously with a carbon pen.

Even when Bai Ling walked in, the figure did not react at all, but the writing speed of the carbon pen became faster and faster, even to a level that could almost be called "crazy".

The formula unfolded like flowing water, and countless wonderful numbers fell on the paper one after another, and were classified and calculated in a horizontal measurement that was as precise as a computer, until one conclusion after another was reached...

Then overthrow.

Although he couldn't quite understand it, Bai Ling could probably guess how anxious and restless the writer was just by looking at the countless big "X"s on the paper.

Tsk, it seems that even after receiving education in his original world, Sun Yuanrang still tends to get stuck in a rut.

Shaking his head, Bai Ling's consciousness subsided again.

He had the impression that the diary seemed to contain the formula for the future.

Perhaps my original self had anticipated that a similar situation might occur, so he specially copied this thing down on the Internet in the future.

After spending a few minutes comparing, Bai Ling finally found what Sun Yuanrang was thinking about in an inconspicuous corner.

After pondering for a moment, Bai Ling picked up a pen from the side.

Sun Yuanrang, who was still deep in thought at this moment, paid no attention to what was happening around him.

In fact, he was currently struggling with an extremely complex and difficult mathematical problem, to the point where he had completely forgotten everything about his surroundings.

If someone stabbed a knife into his chest at this time, he would not necessarily be able to feel the coolness of the blood flowing. Instead, he would only feel that his brain was rusting and that he was thinking faster and faster.

Of course, this kind of thing is impossible. Apart from other things, the security of the community is still good. And usually no one will specifically look for him, so Sun Yuanrang can be so confident and bold to concentrate on thinking carefully.

However, today, a "knife" really entered his room.

That is the sharp knife of thinking.

The carbon pen lightly touched one of Sun Yuanrang's formulas, and then, at a speed that Sun Yuanrang could not react at all, he drew a long line of column calculations in a relaxed and freehand manner.

who?!

No matter how stupid he was, Sun Yuanrang realized what was happening at this moment.

However, at this moment, he didn't care much about his own safety.

In fact, he was furious now, but he was furious about something else.

He did not immediately take warning, but instead started to curse: "What the hell is that crap you wrote? Don't scribble on my manuscript! Do you know what this represents? This is the future of mankind..."

However, before he could finish his words, he was deeply attracted by the long string of numbers.

These simple numbers look so beautiful in Sun Yuanrang's eyes, and every stroke depicts the delicacy and beauty that is no less than Aphrodite. In Sun Yuanrang's view, these characters are simply the source of inspiration bestowed by the Muse on artists, shining with the light of wisdom and art in the wonderful harmony...

With a "click", the carbon pen in Sun Yuan's hand fell onto the paper.

He stared blankly at the characters drawn by the pen tip, and in a trance he felt a sense of sudden enlightenment.

"So that's it," he murmured to himself, "So that's it..."

He finally understood everything.

This feeling is as refreshing as feeling the cool water drops brushing against your chest under the shower head in the hot summer, making you want to linger and wander.

With a sense of satisfaction and joy, he lay back on the chair, his whole body limp as if his spine had been removed.

"Perfect, too perfect," Sun Yuanrang muttered to himself, "How did you come up with all this? Are you a god? Are you the Muse sent by an angel to save me?"

Perhaps because he had completed his long-term research, Sun Yuanrang looked very relaxed.

He even had time for a joke.

Soon, the person who picked up the pen put down the carbon pen, and the pen holder turned "gurglingly" on the table.

"Angels and Muses are not from the same system," a voice came from beside Sun Yuanrang, "What's more, in the future, the word 'God' will not be a good adjective for humans."

"The only one who can solve the mystery is you. Only you have this ability."

What is this sound?!

Hearing this familiar voice, Sun Yuanrang suddenly opened his eyes!

He looked behind him first.

The fair hands picked up the manuscript paper, gently shook off the dust on it, and then stuffed it into Sun Yuanrang's arms, asking him to hold it tightly.

"I have brought back the answer you seek from the future," the man chuckled, "Take it, it is your treasure."

"Or in other words, it is the 'only solution' that your future self has spent years searching for. It is also the key that connects the past and the future, and it is the foundation for the future destiny of mankind."

The man smiled and said, "Treasure it."

When he saw this person, Sun Yuanrang couldn't believe it at first.

He opened his mouth in surprise, and after a long while he stammered, "You...you..."

After a long while, he finally managed to utter: "You are back, prophet."

"Yeah, I'm back."

Bai Ling nodded slightly: "Long time no see, senior."
