After a while, Sugar Candy brought water to Tilly's maid, and the captured human soldiers lined up to get water to drink under the command of Muller. Since these human captives were not captured by Lu Jingzhi, he could only provide limited care, and the ultimate fate of these people was likely to be to enter the soul refining pool, and their souls and bodies would be separated. The flesh becomes a zombie, starting from the lowest level of undead slaves, slowly growing into soldiers and knights, and if you are lucky, you will be assigned a good soul, and you can also train to become a high-level knight, but most of the flesh will not get the protection it should be in the initial stage, and slowly decay. Souls that yield will be cleansed and lose their memories and become souls attached to other bodies, while those who do not give in will be trapped in the bagpipes of the Dementors and slowly blow away, disappearing forever.

Lu Jingzhi is very reluctant to let these human beings enter this stage, even if these modern people who exude vitality in their mixed bodies become prisoners of war, they should be treated like modern prisoners of war, instead of being brutally executed, and even in the end, their souls will not be able to rest in peace. But there was nothing he could do, after all, in a way, he was just another captive who was treated favorably. So he did everything he could to stop them and give them some water to drink and rest, even if it was just to sit on the ground for a while.

When Tilly's undead knight took away the captives captured by his subordinates, Lu Jingzhi hugged Tangtang and covered her eyes with his body, unable to bear to see the scene of those humans being taken away, and turned around himself, tears filled his eyes for a while. If I could, I would save you, but only if I could save myself and Sugar's life. Lu Jingzhi said to these people in his heart.

"Brother Jing, you hugged me too tightly, I couldn't breathe. Sugar Candy shouted in his arms.

"I'm sorry," Lu Jingzhi relaxed a little, but still stood in front of Tangtang, "I'm sorry." He repeated, not knowing if he was apologizing to Sugar Candy or to the humans who had been taken away.

In the afternoon, it was experimental time, Lu Jingzhi got two iron bowls, buckled together to form an irregular spherical shape, he used clay paste on them, made a relatively standard spherical mud germ layer, only about 1 mm thick, and carefully cut it when it was halfway through the shade, so that Tangtang redrew an explosive spell pattern on it, but these figures were divided into two halves. Lu Jingzhi carefully aligned the two figures, only a thin layer of parchment paper was spaced in the middle. Carefully cover the iron bowl on the outside, and then tie it with elastic plant fibers - it is a kind of tendon drawn from the stem of the sunflower, which has a certain flexibility, and can be elongated and can spring back when you let go. At the same time, he left one end of the parchment paper outside the iron bowl and glued a wooden handle to one side of the iron bowl with clay.

"Sister Rong'er, do you know what we got this?" Lu Jingzhi asked.

Sugar Candy nodded and said, "Isn't this an explosion spell?" Even the graphics were just drawn by himself, what do you not know?

Lu Jingzhi smiled and said, "This is a grenade, and it blows up very powerfully." ”

Sugar Candy sighed and said, "It turned out to be a grenade, I guess it's a grenade for those undead, because I've never seen it this big on TV." ”

Lu Jingzhi blushed for a while, this grenade was indeed too big, and he couldn't throw it far. If it's as powerful as a grenade in modern warfare, you're likely to blow yourself up first. "I'll make smaller ones in the future, but no one will help us right now. Lu Jingzhi said with a little annoyance. Then, he pulled Tangtang behind a mound of dirt, then pulled out the parchment paper vigorously, threw the iron bowl in his hand, and quickly squatted down with Tangtang.

There was no movement.

After 1 minute, there was still no movement.

After 3 minutes, Lu Jingzhi was really impatient to wait, stood up, and looked at the grenade made of iron bowls, which was lying there quietly, not moving.

"Sister Rong'er, can you see the flow of elements, help me see if there are any elements flowing into the grenade?!" Lu Jingzhi whispered to Tangtang, as if he was afraid that his voice would be loud and scare the earthen grenade.

Tangtang stood up, glanced at it, and said, "Hardly, just a little bit of flowing, such a flow will hardly explode." ”

Lu Jingzhi sat on the mound of dirt in disappointment, thinking about what he had made a mistake.

Ordinary grenades can explode as long as there is explosives, fuses and projectiles, and the explosion is blocked by the iron shell of the projectile, which will increase the pressure and strengthen the power of the explosion. And the grenade made by himself, even if it does not have a strong enough shell, at least the effect of deflagration should be there, if there is no deflagration, it can only be said that there is a problem with the explosives inside - that is, the spell pattern is wrong.

Thinking of this, Lu Jingzhi jumped up and rushed over to disassemble the grenade. Sugar Candy saw that the moment the clay was torn apart, the flow of the elements stopped as the spell was broken. At this time, Lu Jingzhi also shouted: "So that's the case, I'm really stupid." ”

Previous spell experiments were done with the ability to absorb elements from the outside world. In other words, this sealing, which was carried out to increase the power of the explosion, actually cut off the inflow of external elements, which led to the failure of the explosion. Since Tangtang had seen the flow of the elements just now, it meant that the spell was still functioning normally to absorb the elements, but because the amount was too small, it couldn't work at all.

"Sister Rong'er, it seems that there is no play, there is no way for me to let the elements flow into a closed shell. Lu Jingzhi thought for a long time, and lay down on the ground dejectedly, "Pity me for being a genius this day, I died like this, is God really unwilling to help me survive in this world full of danger and ugliness?"

"Brother Jing, didn't you survive? And you survived quite well. Tangtang sat next to Lu Jingzhi, and she was not worried about Lu Jingzhi's appearance at all. When he encounters any difficulties, he always complains for a long time first, and then inspiration comes, and the problem will naturally be solved.

Sugar Candy is not wrong at all, as a human being, he can become a high-level knight in the world of the undead, which is already unique. It's hard to tell, but it's certainly unprecedented. can live so well in the world of the undead, one is not strength, and the other is not conspiracy, but his own ingenuity. Then, as long as you give full play to your ingenuity, you will definitely be able to achieve your goals.

"Sister Rong'er, you say, why can the grenade explode, but mine can't?" Lu Jingzhi said distressedly.

Tangtang didn't understand why, if she had time, she would rather deduce her golden arrow. However, in order to comfort Lu Jingzhi, she still followed his words and said, "How did the real grenade explode?"

Lu Jingzhi drew a grenade with a wooden handle on the ground, with a shell on the outside, explosives on the inside, and a detonator on the inside. "That's it, as soon as the line is pulled, the delay begins, and after 10 seconds, it triggers the thunder mercury, which will detonate the explosive in a very short time, and then the grenade will explode. ”

Sugar Candy still didn't understand, but it didn't stop her from continuing to ask, "And what is the explosive you have here?"

Lu Jingzhi smiled and said: "It's the spell contract you draw......" Speaking of this, he was suddenly stunned, is the explosive really a spell contract? No, it is at most a detonation device, and the explosive is a simpler thing. Element. Thinking of this, he jumped up from the ground happily, laughed, and immediately said to Tangtang after a short break in laughter: "Sister Rong'er, good sister, do me a favor, help me draw a few spells that can store the elements, I want to absorb enough elements and put them in the iron bowl." ”

Tangtang saw Lu Jingzhi jumping up and laughing like crazy, he was startled at first, but when he made a request, he was relieved, at least Brother Jing's brain was still normal. As for the weird behavior, what is it? In this world full of undead spirits, is there anyone more normal than Brother Jing? She thought to herself, her hands were not idle, she picked up the pen and brushed a few strokes on the paper, and hooked out four magic arrays, which were the elements of fire, water, earth, and life to gather and store the spell.

Lu Jingzhi put the spell pattern on the mound to absorb the elements of nature, because he couldn't see the changes in the elements, so he had to let Tangtang often look at it, and if it was almost there, call him. It was late in the evening that Sugar Candy told him that the parchment had absorbed all the elements.

"How much full?" he was a little unsure, "how much bigger than the exploding spell that I carved into the stone before?"

"It's a big one!" Sugar Candy made a circle with her hand, but felt that it was not big enough, and expanded her two hands outward a little.

"......" Lu Jingzhi laughed, "How many times more than that?" that is, ......" He didn't know how to describe it, such a cute girl, no one would be anxious with her, he only hated himself for not teaching her well.

"Oh...... That's about 600 of those spell shapes. "Tangtang still knows the concept of how many times, but I didn't think about how to quantify it at first. Because this spell pattern is stored in multiple layers in an array, each layer has a circle to dilute their concentration, so until it is full, there is no eruption.

More than 600 times, that is almost the charge of a light aerial bomb, and in terms of artillery, at least it is the power of artillery above 100mm. Such a power will lift yourself and Sugar Candy into the sky.

"It's not going to work, it's too dangerous. Lu Jingzhi said hesitantly, it wasn't that he didn't want to test and detonate a bomb with such a big power, in fact, he dreamed about it. It's just that he will never put himself under the power of such a bomb until there is no safe way. "Sister Rong'er, can you think of a way to reduce the weight of this thing, just 1 times more than a stone bomb. ”

Tangtang thought for a moment and nodded, "Yes." ”

"Really?" Lu Jingzhi became happy again, "What?"

"I tore them up and redrew them on paper. "Sugar Candy is serious.

Lu Jingzhi almost squirted out a mouthful of old blood.

What is the future of the trial production of grenades? I want to know what happens next, and let's see the next breakdown.
