The difference between a scientist and an engineer is that one is responsible for thinking and the other is responsible for doing. The person who thinks is as important as the person who does it. Lu Jingzhi is a scientist in the study of spells, and he deduces in his mind how to draw the graphics of these spells, how to match them, and what kind of effect they will have. Sugar Candy became his engineer, responsible for drawing the exact spell patterns he had imagined.

After finding a stone that was relatively flat in the size of a palm, Lu Jingzhi began the first step of the experiment. He calculates the effect of the stone's surface on the figure, then adjusts it to make adjustments, and then has Sugar Candy carve a short sword into the stone according to the previous Explosion Spell pattern. After carving, Lu Jingzhi grabbed the stone and threw it out. The stone flew out about six or seven meters, rolled on the ground a few times, and came to a steady stop.

Nothing happens, maybe it's a failure.

Lu Jingzhi wanted to walk over and pick up the stone to take a look, but as soon as he took a step, he was stopped by Tangtang.

"It doesn't matter, it's not moving. Lu Jingzhi always felt unwilling, maybe he was thinking wrong, maybe Tangtang didn't draw it right, he wanted to figure things out. This thought flooded his mind, and he lost the coolness that a true scientist should have.

"I saw many, much, too much, those red breaths, flying onto the stones. Tangtang said a little incoherently, "It's dangerous there!" Anyway, just hold Brother Jing and don't let him go.

At that moment, the stone exploded with a clatter, and the debris flew in a flew, and a slightly larger stone flew in front of the two of them. The force of this explosion was much greater than what had been tested in the tent before. At the same time, because the carrier is a stone, it also forms a fragment killing effect. If someone happens to be next to a rock, there will be a lot of broken stone chips embedded in their body.

Lu Jingzhi suddenly understood what he was wrong, he forgot that the stone itself was a pro-soil material. If it is on paper, a group of earth element convergence figures can only get 6 earth elements, and generally in order to match enough two acid effects, three to four groups of earth element convergence figures are required. But this time, it is obvious that the earth element is too strong, and it condenses into a relatively solid converging soil layer on the periphery of the inner ring, and when other elements are detonated in the inner ring, they are restricted by the converging formation, so that a greater pressure is formed, which triggers a greater explosion until the converging formation is exploded.

This is also because Lu Jingzhi lacks experimental support, and if there is enough experimental data, such results should not occur. In order to get more experimental materials, he pulled Sugar Candy and searched farther outside the barracks.

So, they met some people.

It was the first time he had seen a heavily armed human soldier since he arrived in the realm of the undead, and he had seen so many at once.

At that time, Lu Jingzhi and Tangtang had just rounded a small mountain col when they saw a convoy parked on the side of the road to rest. The familiar khaki combat suit, camouflage jeep, .50 machine gun on the car, and the GI with an assault rifle on his back all gave him the feeling of being in a movie. Perhaps out of fear of the weapons in the car, or perhaps wary of strangers, he did not run up for help, but chose to pull Sugar Candy, quietly retreated, and hid.

The GIs rested by the car, eating, and talking to each other. But because it was too far away, Lu Jingzhi couldn't hear what they were talking about. What are these people doing here? Are they looking for themselves and Tangtang? Do you want to go out and tell them that they can take you back to your old home?

Just as he was thinking, suddenly a group of scout cavalry of the principality army came around from the other side of the mountain and saw the convoy from a distance. They immediately went to ask questions, and were spotted by the sentry on guard two kilometers away. The sentry shouted something, and all those who were resting threw down what they were holding, ran to the car and the side of the car, and stood guard with their guns. From the discovery to the formation of an effective defensive lineup, it took less than 1 minute.

This is an elite force, at least well-trained. Lu Jingzhi thought to himself.

It took about another 5 minutes for the Duchy's undead scout cavalry to come running. About 200 meters away, a soldier ran out from the front of the convoy and held out his left hand to ask them to stop. But the cavalry could not restrain their horses for a moment, and rushed towards the soldier. Seeing that the other party could not stop for a while, the soldier hurriedly retreated, continued to raise his left hand to make the other party stop, and at the same time raised his right assault rifle and aimed it at the oncoming horse.

Seeing that the dispute between the two sides was about to arise, the undead cavalry led by him grabbed the reins with all his might, stopped, and asked down with a proud expression, completely ignoring the machine guns mounted on the jeep opposite. The human soldier replied a little nervously, the distance between him and the other party was too close, although he had a weapon advantage, but this distance could only aim at two or three people at most, and once the other party came like a tide, he would definitely suffer. After a few words between the two sides, the undead cavalry led by him was obviously dissatisfied, drew his sword, and gave an order backwards, and the other undead cavalry immediately came around from both sides to surround the convoy. Seeing this, the human soldier brandished his spear and tried to stop it, but the undead soldier in front of him was annoyed, picked up his sword and slashed it off his head. I saw a flash of fire in the convoy, and the sword in the hand of the undead knight led by him froze, and the chopping action was much more off, and he narrowly brushed the side of the human soldier, startling the human soldier. This series of actions was like a rabbit falling like a rabbit, and it was completed in an instant, and only then did Lu Jingzhi hear a slight snapping sound in the distance. It should be the sound of a small-caliber assault rifle, and it changed from crisp to muffled when it was far away. At this moment, the human soldier in front of him also opened fire on the undead cavalry, and the muzzle flame in his hand flickered, and the muzzle fire of the soldiers in the convoy also flashed. The cavalry that rushed over was knocked down from their horses in pieces, but the small-caliber bullets did not have much effect on the undead, and after experiencing a rain of bullets, the undead cavalry stood up from the ground.

The soldier at the front threw down his gun in fright and ran into the convoy, seemingly seeing the faces of the undead under his knocked helmet. The small arms in the convoy rang out again, only this time few were knocked down. At this time, Lu Jingzhi saw that the .50 machine gun on the car also spewed fire, and an undead cavalryman who was facing him was shot three times in the chest and was directly broken into two, and then heard the sound of "Tututu" heavy fire.

There were more than a dozen vehicles in the entire convoy, and the first few cars were equipped with top fire, some were .50 machine guns, some were 40mm automatic grenade launchers, and when they saw that something was wrong, these vehicles opened fire at the same time, and the battlefield was lively. On one side were the ignorant and fearless undead scout cavalry, and on the other side were the human soldiers desperately shooting fire to block them, and the iron and fire on both sides collided quickly, and the effect was amazing. There were only about 20 undead scouts in that group, and they were to be spread out along the march route to ensure that they would not be attacked by the enemy while marching. At this time, they raised their knives to rush a fire net of several hundred meters, even if the undead were not afraid of life and death, they could not withstand the power of large-caliber bullets and grenades, and when the last undead scout was smashed into broken limbs, they could only rush halfway the distance.

Even if it is an immortal body, as long as it is not invulnerable, it is just as weak in the face of modern firepower.

Lu Jingzhi had already run back with Sugar Candy when the first undead cavalry was killed. He didn't know what these human soldiers were for, but he knew that if he didn't run, he would probably attract a bunch of large-caliber bullets.

Back in the barracks, tell Tilly what she saw as it was, Tilly is also used to war, and knows that human weapons are already very powerful, and she even has more powerful weapons, but it is far from the time to clash with humans head-on. After thinking about it for a while, Tilly decided to go back 40 kilometers.

40 kilometers is a day's journey for non-mechanized troops, but Tilly is not at all worried that her troops will be overtaken by mechanized human soldiers. She knew that in such an environment where the air was full of elements, it wouldn't take long for engines to be scrapped, and electronics would be eroded by water and unusable. Even devices that are isolated from the air will gradually be affected by the elements and lose their effectiveness. Lu Jingzhi proposed several times to speed up the retreating march, but Tilly didn't take it seriously, just to comfort him, symbolically sent several teams of scouts to the queen of the palace.

"Don't worry, this is almost the limit of the human mechanized army. Tilly rode on the undead horse and said to Lu Jingzhi and Sugar Candy, who were being carried by several human slaves. It was not that they refused to walk on their own, but that Tilly saw that they had short legs and insufficient stamina, so she specially found a few handy men from among the slaves who accompanied the army, made two sliding rods, and carried them along.

"How far is this," Lu Jing Yifu looked disappreliant, "If the road conditions are good, one foot on the accelerator, and you will catch up in 20 minutes." "40 kilometers, if you go by the speed of the highway, it's really 20 minutes. But these foot cavalry, who walked on two or four legs, had to walk for a day.

Not long after, the first scouts returned and reported to Tilly, and sure enough, the humans were still parked there and did not chase them, probably because the terrible cars were not moving.

Without .50 caliber machine guns and 40mm grenade launchers, those human weapons would hardly work against the undead. Lu Jingzhi thought about it, and suddenly asked Tilly: "Your Excellency Tilly, you seem to know their situation very well." "As the Grand Commander of the Principality of the Undead, it is unusual to know the mechanical characteristics of humans so well, and to be able to deliberately keep a safe distance. You must know that the previous undead scouts didn't even know what a gun was, and dared to lead soldiers to hit the muzzle.

Tilly was silent, and walked out of the distance, before she said slowly, "I've been with the undead for so long, and even I have almost forgotten that I am a human." ”

Does Tilly know a lot about humans? How does she resolve the crisis caused by human soldiers?
