The scientists are still quite fast. To paraphrase a famous saying: the fire of passion is poured with the oil of money, and the efficiency of work is amazing. After the first data analysis came out, the scientists had a long discussion, which lasted from 9 a.m. until 4:30 p.m. the next day. Some of them couldn't stay up late, and they only rested in the rest cabin from the piano. The rest cabin is a bit like a capsule hotel, but the facilities inside are much better, which can help people fall into a deep sleep in a short time, and sleeping in the rest cabin for two or three hours can have the effect of sleeping at home for 8 hours. Younger people basically didn't close their eyes for more than 30 hours and took anti-fatigue drinks. In this round-the-clock work, more analytical equipment was brought in, and more scientists were put in.

When the research team expanded from a dozen to several hundred, they finally came to the first conclusion that due to the influence of the natural environment, electrical appliances will first fail when about 10 kilometers into the hole, and gasoline and diesel engines will stop working at 15 to 20 kilometers.

"That's what you've been doing for a week?" the general almost threw the report in the face of Malcom, who rushed over to report, "My soldiers reported this to me a week ago!"

"Mr. General," Malcolm explained, suppressing the disgruntled tone in his own words, "your soldiers are reporting only from experience, and ours from the results of research, and it is clear that our report is more authoritative. ”

"But it's useless. The general is worthy of being a person who has seen the big world, and knows that quarrels are useless, so he quickly calmed down, "I hope your team can come up with a more detailed report, such as how we can solve these incredible phenomena." ”

"We don't know this yet...... Malcolm lost his momentum at once, and the general poked him in the underbelly.

"And what is the cause of all this?" asked the general tepidly.

"This ...... We're also working on ...... "Malcom's face was oozing with sweat."

"So, when will we be able to figure it out?" the general asked, holding his arms together.

"This ...... Also ...... I don't know ......" Malcolm was completely defeated, and he suddenly wanted to run away. When dealing with scientists, he is very skilled, but when dealing with soldiers, he loses a lot in terms of momentum.

The general made a gesture of please, and Malcolm ran away without saying a word, all he could think of was to expel the time-wasting guys from his project team, no, Mr. Jean's project team.

Scientists did not provide much useful information, but the soldiers on the front line made a very practical suggestion: perhaps horse-drawn carts could be used to replenish and transport combat supplies.

After reading this suggestion, the general's eyes lit up, the carriage did not have electronic equipment, nor did it have an internal combustion engine, and using the carriage to transport some weapons in it could expand the search area, and also strengthen the soldiers' survival and combat capabilities. If you think of it, you must do it! This has always been the motto of the general. Within 72 hours, dozens of old wagons made of lightweight materials were made, and ten times as many horses were brought from farms and pastures in the south. Although horses are no longer the main tool of production, there are still many cowboy people who are willing to keep a few, even if it is as a pet. However, the quality of this kind of horse is uneven, but fortunately, the horse that pulls the cart does not need to be of good quality, as long as it has strength.

Before the carriage formed an effective supply line, the general did not dare to scatter the limited soldiers farther away, the state of being released and not being able to take it back was so terrible that he had a feeling of blindness - a man accustomed to a completely transparent battlefield suddenly became blind and could not see anything.

The soldiers on the front line have slowly advanced to a distance of about 25 kilometers, where traces of explosives and mass camping have been found, strangely no people or animals have been found at all, and from the traces on the ground, there is a large army here, but it has been withdrawn.

Tilly had withdrawn three days earlier, and she had let Lu Jingzhi walk in the middle with the human captives, but fortunately, although the humans didn't need to make spell grenades for the time being, they weren't mistreated for being useless. Lu Jingzhi laid the wheels removed from the jeep with wooden planks and connected them with ropes in the middle, turning them into the appearance of a flatbed train. The grenades and printing presses he had made, and even the lime powder that had been burned, were carefully placed on the cart and dragged away by the zombie minions of the undead army. He took the Mueller team and others to sit on the flatbed truck, guarding those things to avoid being damaged and lost in transportation.

There are also many knights who have raised objections, after all, Lu Jingzhi and Tangtang are just that, although they are also prisoners of war, but they are the high-level knights and knights of the undead Empire, but why can those human captives sit in the car and let the undead pull them away?

Lu Jingzhi's answer was very simple: Pull me and give you a high-level magic scroll called a "grenade" when you get to the place. So every knight who raised objections expressed their willingness to serve the magician.

Tilly just wants them to have no problems, as for Lu Jingzhi's refusal to walk in order to save effort and be lazy, naturally he has his own methods to do it, and he will settle it by himself if he makes any demon moths.

The army retreated 60 kilometers back in a day, basically without stopping. If it is a march of manpower or animal power, the man will not be tired and the horse will be tired. But these undead seem to have endless energy, and they don't need to rest at all, even if they only walk 5 kilometers an hour, but these undead can walk for 12 hours in a row.

On the fourth day, Tilly ordered not to go any further, to camp and rest, and at the same time sent dozens of scouts to explore the way to come, and to report back as soon as they found it, and not to engage in war with humans without permission.

"Lu Jingzhi, you can continue your research here. Tilly re-assigned two barracks to Lu Jingzhi and his people, her focus was on marching and fighting, and the time to accompany Tangtang was getting less and less, Lu Jingzhi was basically not ranked, and being able to get such an instruction showed that Tilly had taken his affairs to heart.

Lu Jingzhi was not idle all the way, he fully analyzed the mixing ratio and catalytic method of different elements, and found that these spells and alchemy were really similar. "Maybe it's the same thing," while Tilly wasn't there, Lu Jingzhi whispered to Tangtang, "I think it's because that young old woman doesn't understand alchemy." ”

"Young old woman?" Sugar Candy thought for a moment before she realized that Brother Jing was talking about Tilly, she smiled and said, "Don't talk so ugly about Sister Tilly. ”

Lu Jingzhi couldn't help but be stunned when he saw Sugar Candy smiling cutely, and after a while, he suddenly said, "I know, this is a flat projection of a three-dimensional model." ”

Seeing that he said solemnly, Tangtang hurriedly asked, "What is a planar projection?"

Lu Jingzhi pulled Tangtang to a lamp, pointed to his shadow on the ground and said, "This is the projection." Then he pointed to himself, "I'm three-dimensional, right? I have height...... "I have a height" and compared his head with his hand, "Width...... "I compared my shoulder width with my hand," and "there is thickness," I stroked my chest and touched my back with my hand, "So you see, I have three dimensions: length, width and height, which means that I am three-dimensional." ”

Sugar Candy smiled and said, "It's not the first day I saw you, so I don't know how tall and wide you are." ”

Lu Jingzhi smiled: "Okay, I'm just a metaphor, I mean, the spell we draw is actually the same as alchemy, it is a formula to guide the synthesis of elements, just like when we were in school, the teacher said that hydrogen and oxygen combustion will produce water." Seeing that Tang Tang didn't understand what he didn't understand, he automatically skipped a large section of chemistry knowledge and said directly: "What we see is the change of the elements in the spell, in fact, they have already changed in the air. It's just that there is no spell, and we can't see it out of thin air. It's like when we're in a place where there's no light source, there's no shadow, and if you just look at the ground and don't look up, you don't know where I'm at. ”

Tangtang lowered his head, looked at Lu Jingzhi's shadow, raised his head again, looked at him, and said a little blankly: "I can see it." ”

Lu Jingzhi saw that Tangtang was thinking, knowing that she understood, he couldn't help but be proud of his excellent explanation, and suddenly heard Tangtang say that he could see it, so he smiled and said: "You can see it here, but not in other places." ”

Sugar Candy shook her head and said, "I can see it." ”

Lu Jingzhi pulled Tangtang and walked away a few steps, until there was no shadow on the ground, and then said: "Look, now you don't look up at me, just look at the ground, can you know where I am?"

Tangtang pointed at his hand without raising his head, which happened to be where Lu Jingzhi was.

"Did you hear my voice?" Lu Jingzhi tiptoed away a few steps, Tangtang's fingers kept chasing him, "Can you know this?" Lu Jingzhi walked more slowly, and Tangtang still pointed at him without raising his head.

Seeing that Tangtang was accurately pointed out in several directions, Lu Jingzhi had no choice but to give up and asked, "Sister Rong'er, how did you do it?"

Sugar Candy said: "The air is flowing when you walk, I just look at the dust in front of my eyes, and I know how you are walking." ”

Lu Jingzhi was dumbfounded, his metaphor completely failed, and the relationship between projection and three-dimensional was so defeated by the observation of the sugar candy golden arrow. He waved his hand, said nothing, and ran to the side to build a three-dimensional model on paper. Tangtang is still wondering, why is Brother Jing unhappy? Could it be that he just wanted to play a game of hide and seek with himself, and was found out by himself at once?

A spell is a magical thing, but since it is an element, there must be many possible combinations. There are 118 stable elements on the periodic table of chemical elements, while there are only five elements in alchemy. However, these five elements can mimic the chemical properties of stable elements according to different ratios. But the essence of chemistry is the recombination of molecular clusters at the physical level and the exchange of common electrons, so what is the essence of the change of elements? Lu Jingzhi looked at Tang Tang blankly, he always had a thought, these questions, maybe Tang Tang is the key to the answer.

Did Tangtang see that Lu Jingzhi was looking at her? Did Lu Jingzhi solve these problems? I want to know what happened next, and see the next decomposition.
