Deducing the Timeline!

On the stall.

As the prompt board appeared, Xu Yun suddenly found that everything around him had suddenly stopped:

For example, at a stall seven or eight meters away from him, a vendor was arguing with a customer with a flushed face. It looked like a physical fight was about to break out, but their expressions suddenly froze, making them look like two lifelike inflatable dolls.

Another example was the owner of a fruit stall not far away, who was casually crossing his legs and tossing an apple in his hand. The apple then stopped abruptly in mid-air. Newton would probably roll over in his grave if he saw this. Uh, wait, Newton was also on the scene.

Xu Yun turned around and found Little Ox grinning widely, his face beaming. Even the bits of shredded bean stuck to his back teeth were clearly visible.

Motionless, as if frozen.

Grantham, or rather, the entire spacetime of 1665.

It had stopped without any warning.

The entire world, except for Xu Yun's life, was ticking backward at -1 second.

Immediately after, a halo quietly appeared beneath his feet, slowly enveloping his entire body.

Xu Yun was very familiar with this halo—it was obvious, just as the prompt had said, his newbie quest was complete, and he was about to return to reality.

And in the last moment before disappearing, the thought that flashed through Xu Yun's mind was:

Goddamn drinking buddies!

So, I went through all the trouble of helping you solve a bunch of academic problems, and it's not even worth a few guineas?

Old Man Newton, you truly live up to your reputation!

Then came another wave of dizziness, just like when he arrived. When Xu Yun came to his senses, he was once again in that confined space.

At this moment, the three doors were still floating in front of him, but the leftmost door, representing the spacetime of 1665, was now a dark gray. The original '100/100' on it had also changed to '0/100'.

Xu Yun had seen this scene many times over the past decade—it meant that to open that door again, he would need to meet the requirement of his knowledge points returning to 100.

As for whether these knowledge points were related only to academic degrees or knowledge reserves, that would require further research.

However, besides the entire door turning dark gray, Xu Yun also noticed that on the ground in front of this closed door, a small, dark gold box was now placed.

Xu Yun pondered for a few seconds, then decisively walked forward and picked up the box.

Although this space seemed a bit dodgy, if it truly wanted to do anything to him, it could have turned him into a corpse or a vegetable ten years ago.

As soon as the box was in his hand, it suddenly transformed into another fluorescent screen:

[Detected, 'Wall-facer' newbie quest complete. Proceed with evaluation?]

FBIWarning:

As the 'Wall-facer' is currently in a multi-node mode instance, this deduction result is for scoring purposes only. Time within the instance is locked. The 'Wall-facer' will automatically resume from the return screen upon next entry. Proceed?

Below were two options:

[Yes] [o damn it k]

Xu Yun: "..."

So this thing really has issues, right?

However, speaking of which, while the dialogue box was cheeky, it revealed quite a bit of information:

According to the dialogue box, the halo would conduct a sand-table-like deduction based on Xu Yun's previous actions, thereby making a certain scoring judgment.

The time within Little Ox's spacetime door was locked, meaning that the next time Xu Yun entered it, he would still see Little Ox with those bits of shredded bean in his back teeth.

He then sighed somewhat melancholically and clicked the 'Yes' option on the left.

Soon, the dialogue box began to change.

[Academic achievements]:

Influenced by the Wall-facer authority, the current available academic weighting total is [4], with weighting items arranged in chronological order:

Due to the intervention of a 'Wall-facer', Isaac Newton proposed the light dispersion equation in late December 1665, formally proposed the infinitesimal series concept in March 1666, and proposed Newton's Binomial Theorem.

He then merged the binomial (m/n dimensional) with circular logarithms, proposing the discrete algebraic equation model of (1-X2)=(1-X2)1/2·(1-X2)1/2 = X＋X2＋X3＋...＋Xn and (1-η2)=η＋η2＋η3＋...＋ηn.

[Mathematical formula weighting: 9]

In April 1666, Isaac Newton derived the third-order 'Han Li Expansion', initially consolidating his own fluxions model. Combining this with Kepler's Third Law, he successfully derived the Law of Universal Gravitation. Principia Mathematica, originally scheduled for publication in 1687, was released early in 1679.

[Core theory weighting: 17]

Regarding elastic forces, Newton proposed the theory in 1674 that "after solid materials are subjected to force, there is a linear relationship between stress and strain within the material," expressed as F=k·x, historically known as Newton's laws of mechanics. Later generations further derived the triple expression of the generalized Newton's laws of mechanics, increasing the content covered in the national college entrance examination to 31 points.

[Mechanics variation weighting: 13]

Influenced by the 'Wall-facer's' proposed product of refractive angles, Newton became more convinced of the particle nature of light than in history. The integrated derivation equation perfectly explained most optical problems of the time, giving him an absolute advantage in his debate with Huygens.

[Associated character changes] (arranged in ascending order):

Ruben Holland:

Tiffany Boley's husband. Formerly the chief tailor at the 'Bolee Estate' in Grantham, he foresaw the demand for tomatoes with remarkable foresight after tasting ketchup in early December 1665. In early 1666, he mortgaged his property to establish a tomato plantation estate, later becoming the largest fruit supplier in Lincolnshire and surrounding areas.

Yarlin Dilat:

Pastor of St. Titus Didymus Church in Grantham, and the seventh officer of the Lincolnshire Diocese. Due to the significant profits brought to the diocese by promoting ketchup, he was promoted to acting general director of the Nottingham Diocese in July 1666. He proposed an amendment to increase civil rights laws during the drafting of the Bill of Rights, and was later revered as Saint Dilat.

Lilani Escu:

The youngest daughter of William Escu. After the unexpected disappearance of the 'Wall-facer', her personality gradually became withdrawn. She dropped out of school at 15 to work, and at 19, she traveled to Leiden University in the Netherlands in an attempt to find the 'Wall-facer'. She tragically died in a shipwreck.
