Chen Lei was stunned by what I said, and he was writing and drawing on the paper with a pen cap in his mouth, obviously unable to understand it for a while.

At this time, another person invited by Chen Lei, Bei Xixi, the girl with a sun hat who was driving, spoke: "Don't forget the bronze car found in the ancient tomb, that's the point." The Tianwu totem can show that it is not Jiuli, but the Wu people after the fusion or the Wu people of the Yanhuang clan. But whether it is Liangzhu or Yanhuang, it is still doubtful whether bronze can be made at that time. ”

I nodded—though she couldn't see it. She does have two brushes and makes the problem clear in a few words.

I could hear the disdain in her tone, a tone that only someone with a clear and genuine answer would have.

I took out my wife's and grandfather's notes from my pocket and quickly flipped to a page where a simple pattern was depicted on the moldy and yellowed paper - a four-wheeled car.

"Mrs. Grandpa's notes record this kind of bronze car, called: Evil Wheel, of course, how strange this name sounds, I don't know if he was obscene or what, but the strange thing is that he only drew the pattern of the evil wheel, without explanation, and in the back is the record of the twelve ancestors of the ancients. ”

I showed the notes to Chen Lei, and he also frowned, "Forget it, we won't be able to study the reason for a while, so I'll show you this first." So saying, he took out a rusty large coin from his pocket and showed it to me, with an eagle engraved on the obverse of the coin.

Bronze coins are easy to rust, so the correct way to preserve them is to wrap them in brown paper and put them in a ventilated place, or bury them in an unventilated ground like an evil wheel. Judging by the degree of corrosion of the bronze coins, they should be fairly well preserved, but it is impossible to determine whether they were buried in the tomb or preserved by man.

"It's also cast in bronze, which my uncle gave me as a gift when he came home two years ago. He mentioned the bronze coins in the email, telling me to take them with me, and I stuffed one of your travel bags. With that, he opened my travel bag, and turned it over and found an almost identical bronze coin, but with a slightly different carving, a huge tiger head.

It's really strange that I can see that the two bronze coins are not more than a century apart, and the process of minting is basically similar, that is, they are made by a single ethnic group - there will be two or more totems in a single ethnic group?

"While what I'm going to say next may be a bit fantastical, it's true. Chen Lei's expression became serious, and I rarely saw him show such an expression.

For the next ten minutes, he described to me a phenomenon called heavy acceleration (1) with a bunch of theorems from physics.

Since there is so much jargon involved, and that it is difficult to describe it as a liberal arts student, I will use the vernacular to describe it.

The so-called heavy acceleration, according to Chen Lei, is an object with an astonishing mass (or energy) moving at high speed, thus changing the energy distribution of space-time, causing space-time to bend - and the curvature of time is more obvious, and the time around the object will slow down dozens of times, or even a hundred times.

That's why he dared to crash into the Ancestral Witch and shoot down the lamppost just now, because the time around the Heavy Acceleration caused by the Ancestral Witch almost came to a standstill, and even with a high-speed camera, he could only capture their afterimage.

Strangely, the bronze coin was able to resist the heavy acceleration caused by the Ancestral Witch, which was also mentioned by Chen Lei's uncle in the email.

It stands to reason that if Mrs. Grandpa had written about the evil wheel, then the bronze coin that opposed it (I think so) should also have been recorded, but I searched through all the numismatic parts of the notes and found no information about the half-cent.

Chen Lei told me not to dwell on these issues, and everything will be clear when I get to Shandong.

The bus was driven by me, Chen Lei and Bei Xixi in turn, and none of us had a driver's license, but fortunately Chen Lei got one from his house, but even then we didn't dare to drive the highway, just walked along the ordinary highway, and walked trembling along the way. Especially for me, I didn't have any preparation before I set off, and with my rookie experience as a bicycle (and now a motorcycle), the speed of the bus did not exceed 50 during the whole journey.

1: Imagine an object whose mass and energy are distributed very evenly, so that its curvature in space is zero, but the curvature of space-time is not zero, just like the rays around the sun are curved, you can refer to Einstein's "curved tabletop" hypothesis.

Since the Ancestral Witch has a certain mass (assuming, it does not actually exist) and its energy is very strong, it has a strong gravitational field. They attract the surrounding dust to a certain range, and in the upper part of this range they will produce an unusually strong repulsive gravitational force, probably a bit like a "white hole", all the matter moves at high speed in the direction away from the ancestral witch, colliding with the dust outside the range, generating a huge amount of energy radiation, which is how they attack.
