"At this point in time, did Professor Chen appear?"

"Professor Chen Pan had not yet arrived at the Clock Tower to teach at this point in time, and his first public appearance was when the Clock Tower Magic Association was founded, and he joined the Association as a special guest audience."

"It's a pity, I still plan to meet Professor Chen in this era!"

Xia Ge was a little disappointed.

He came to this point in time, and he had a task to ensure that certain events did not cause accidents.

Timeline closure, as the name suggests, is equivalent to denying the possibility of being unfavorable to oneself, so that the final result will always lead to a certain general direction.

For example, the occurrence of a certain major event will trigger a change in later generations and change the whole world.

However, there are many possibilities in the future, and this may not happen due to various factors.

If you want to be sure that this thing will happen, you have to tighten the timeline, negate some unfavorable factors, and let the timeline that may happen disappear, or become relatively non-existent, or make the probability of its occurrence 0·········

In short, it is equivalent to tightening a ball of lines and letting the world move in a general direction, not too outrageous.

Tightening the direction of this mass of lines, so that all the lines are generally in the same direction, is the so-called timeline closure, and it is also the so-called long river of years.

"The principle of time travel, the third rule, the small things can be changed, but the big trend cannot be changed! I guess those who violate this principle have been obliterated by the magicians, and someone must have tried to do so. ”

There are a lot of wizards here, and their tents are invisible and have camouflage magic added to the outside.

The whole camp is set up on a wasteland, and from the outside it looks like a pile of weeds and stones.

"There's enemy traps, Muggle dispersals, and a couple of early warning spells I haven't heard of."

Xia Ge was in the corner of the camp, standing in front of a tent, carefully observing the traces of magic.

"Taiyi, record these scenes, and when I get back, I'm going to make a short paper on this topic, about the analysis of magic commonly used by wizards camping outside."

The light that was imperceptible to the naked eye flashed by, and because the energy radiation was so weak, the crude magic of the wizards was not even aware of it.

This is the scanning function of the personal light brain, which specializes in mathematical modeling of various magics, and it only takes a simple transmission to collect all the magic data on this tent.

"I'll see, these models of magic········· It's too primitive, most of the energy is wasted, judging by this energy decay rate, it will completely fail in less than four hours, which is a low efficiency in the use of power. ”

"Taiyi, record what I just said, and then, record the whole process, this is my thesis material."

"Yes, sir, I wish you all the best in your career."

Xia Ge walked through the camp one by one, recording the protective magic that was placed on each camp.

He walked around here, but the wizards in the camp turned a blind eye to him.

"Look, this should be a typical dark wizard of this period, it seems to be from Africa, with animal teeth pendants, these crude magical items are said to be used to assist in spellcasting."

The camera comes to a close-up, the African wizard lying on the ground humming a ditty, naked, full of alcohol, and seems to have drunk a lot.

He wore a necklace of teeth around his neck, all of which were the teeth of magical creatures, polished to remove the sharp edges.

"On these necklaces, there are many miniature carvings, we magnify ten times, a hundred times, and we can see a lot of small words, which are ancient magic texts."

"Here, I want to explain that ancient magic is very cumbersome, many spells have to be chanted for dozens of seconds, using ancient magic scripts, and later wizards simplified modern magic, the pronunciation and meaning of the spells are far from the ancient magic versions. Judging from this, it can be judged that the wizards have made quite a few improvements to the ancient magic, which is worth affirming. ”

The camera pans to Xia Ge, and he waves his hand at the camera.

"But wizards are congenitally deficient after all, and they can't be compared to magicians."

"Wizards have never discovered the cause of magic and the principles contained in it, and their magic is nothing more than a repetitive, boring attempt to record the correct one and use and improve it."

"In the beginning, wizards even had all sorts of weird spell-casting rituals and materials, and it was not uncommon to see a wizard throwing out the feces of magical creatures, spitting on the spot, then waving his wand to draw circles, and finally casting a cleansing charm."

This may seem funny, but it's actually because the wizard found the only success story when he first experimented with spells, and he did it at the time, and it was considered a necessary formality. It wasn't until the advent of wizarding schools that these spells were stripped of all sorts of bizarre and unnecessary cumbersome steps."

"It can be seen from here that the magic of wizards is full of all kinds of empiricism and mysticism, which leads to the birth of new magic that is full of randomness and extremely dangerous."

Xia Ge retrieved the database, searched up to 120,000 records, and deleted most of them, leaving 30 representative cases.

"Here I attach thirty representative cases to fully illustrate the dangers of empiricists experimenting with new magic, such as the experiment spell that blew away the entire town, causing more than 8,300 people to disappear, and the ········ who turned themselves into half-humans, half-snakes, moved their heads, and blew up their houses."

Just as Xia Ge was posing for the camera, a figure on the side broke in and penetrated directly from Xia Ge's body, as if Xia Ge was just an illusion.

"Oh, this is my newly developed four-dimensional stealth, don't look at him passing through where I am, in fact, in the four-dimensional space, our coordinates are still quite far away."

He was pleased with his new magic and was happy to share how it worked.

In his plane, new magic is being developed every moment, and except for a few spells with too much influence and destructive power, there is basically no such thing as secrecy.

"The essence of this magic lies in the theory of high-dimensional space, which theoretically holds that the universe has at least ten dimensions, and our naked eyes can only observe three dimensions, so we belong to three-dimensional beings."

"I hide myself in the four-dimensional space, in fact, there can be multiple identical spaces at the same time, but from the three-dimensional coordinates are completely overlapping, the specific principle analysis please see the annexes 00001, 00127, 04099 and 09735, I have made a detailed derivation in it, please see the relevant data model please see 01998 document."
