Tilly suppressed the surprise in her heart and asked Sugarcandy, "How did you do that?"

Tangtang lowered her head a little crampedly and said, "Sister Tilly, I looked at your bell and the method engraved by Brother Jing, and I don't know why." ”

Tilly couldn't laugh or cry for a while, she had learned the spell deed, but it took her years to follow her teacher through every corner of the forest, carving stones, repairing bagpipes, and even carving wind chimes for people living in ancient countries. When the wind blows, the wind chimes will shake the sound of Lanna and help people sleep. It took her a few years to learn all the spell carvings. Her teacher was very grateful to her, and if it wasn't for her as an assistant, maybe the teacher wouldn't have been able to protect the ancient forest for so long. Despite the passage of time, she always remembered the teacher's advice at the time of separation - not to put limited youth on endless spells.

However, Lu Jingzhi, this little guy, actually saw through the essence of the spell at a glance, and Tangtang even carved out the Lanna that he had just flipped through, if it weren't for the limited material and strength, they almost copied this bell. Tilly looked at Tangtang and Lu Jingzhi, sighed, and said, "The talent of the two of you is so good that I can't believe it, and I can't describe it." This cup alone can play no small role in skirmishes. It's just that you haven't learned the spell, and you can't use one-tenth of your talent, if you want to learn, I can teach you from scratch. ”

Lu Jingzhi and Tangtang both found the spell contract interesting, and they couldn't wait to learn more, so they quickly agreed. Tilly didn't hesitate to do so, so she had parchment and ink brought in and drew on the paper. It was a simple little figure, two concentric circles, inscribed and inscribed by a regular hexagon, and at each inner corner of the hexagon there was a straight line to the top of the other inner corner that separated each other. These lines are divided into two equilateral triangles, forming a hexagram, and the central hexagon of the hexagram is surrounded by a circle. At the vertices and intersections of each line, Tilly marked some numbers and symbols.

Lu Jingzhi saw just a graphic, but Tangtang saw a road. Countless auras ran and converged on these paths, but when they reached the innermost circle, they stagnated, and only the red aura seeped inside, while the blue, black, and dark green aura were blocked out. Tangtang looked at the inner circle carefully, and found that the inner circle was not a complete circle, but dozens of polygons of equal length, the length of the side was just as wide as the red breath, and it could rush in, and the blue, black, and dark green breath were much smaller than the red breath, and it should be able to blend in, but because it was too small, it was squeezed by other breaths, and it deviated from the direction, hit the outer corner, and bounced back. So only the red breath can enter, and the other colors cannot.

"Sister Tilly, it's going to burn. Sugar Candy looked at it and suddenly muttered to herself.

"Yes. Tilly's eyes showed a hint of approval, and when she looked at Lu Jingzhi again, she saw that he was at a loss, and she didn't know what Tangtang was talking about, so she sighed, pulled them away a little, and waited for a while, only to see a red flame rising up in the center of the circle, illuminating the big tent in an instant.

Tangtang kept staring at the picture, naturally knowing when the flames would erupt, but Lu Jingzhi didn't know, he was startled by the flames that spewed out, fortunately he stood far away, otherwise he might accidentally let the fire burn. He froze and smiled at Tilly, "Your Excellency Tilly, this is ...... Fire magic?"

Tilly ignored him, turned to Sugar Candy, and asked, "Do you understand?"

Tangtang nodded, and then asked puzzledly, "What are those blue, black, and dark green ones?"

Seeing that she really understood, Tilly hummed in satisfaction and said, "That's water, earth, and life." ”

Tangtang sighed, glanced at Lu Jing, and saw that he was still as confused as Zhanger King Kong, so he immediately ran to his side and asked in a low voice: "Brother Jing, can't you see it? Those breaths of different colors are like tadpoles." ”

Lu Jingzhi is not a tadpole, he is a big toad made of breath, and he can't see it in front of him, he is a complete Muggle in this regard. He had no choice but to shake his head and said, "It doesn't matter if you can't see it, anyway, I don't need to see this, it's also a magician." ”

Tangtang knew that he was speaking freely, but in fact, he was very bored in his heart, so he took his hand and told him carefully about the breath of the swimming. When she talked about the difference in the width of the red breath and the other colors, he exclaimed, as if he had an epiphany, "I know, I know, it's the wavelength." Lu Jingzhi thought back to the figure drawn by Tilly, and said to Tangtang: "Can you draw the figure she drew just now?" Tangtang thought about it, felt that it was not too difficult to draw, nodded vigorously, and without waiting for Lu Jingzhi to say anything, he picked up the pen and copied it again.

As with the effect just now, in a few moments, a flame erupted from the center of the figure, burning the parchment on which it was drawn. But this time, even Lu Jingzhi saw the difference. It turns out that when drawing lines, each line is composed of line segments of different widths, and the line segments are equidistant from each other. For Lu Jingzhi and Tilly, Tangtang seems to be able to draw this figure easily, but for Tangtang himself, this is the first time he has drawn a spell contract, for fear that he will accidentally draw the wrong one and make people laugh.

Lu Jingzhi compared it with his hand and said, "Sister Rong'er, the red qi you said is so wide, right?"

Sugar Candy shook her head, drew a rough idea on the paper, and said, "It's only so wide." Lu Jingzhi looked at it, only about a fraction of his own length, and asked, "How did those red gases get in?" Tangtang used a pen to draw the route of those red gases on the paper, and how the other colored gases were squeezed out. Lu Jingzhi looked at it, thought about it again, nodded and said, "Then what if you change these lines to a different way of drawing?" He dictated and asked Tangtang to draw, only slightly changing the length of the line segments. After a while, a small frosty chill erupted from the center of the figure.

Tilly looked at Lu Jingzhi and Tangtang in surprise, when she was learning the spell contract before, how could she dare not follow the method taught by the teacher?

Under Tangtang's description, Lu Jingzhi found a new kind of figure that could put the earth, fire, and life in the center of the picture in three directions, and gather them together. And in order to increase the concentration of the elements, they also took the initiative to change the circle in the center to a smaller one. Looking at their excitement, Tilly suddenly realized that these two little guys were actually teenagers.

After Lu Jingzhi took the pen and quickly calculated while calculating, while letting Tangtang revise and modify the graphics, Tilly clearly saw that after a few small changes, the inflow of fire and earth elements was doubled, and the water element was mixed with the earth element first, and then mixed with the life element and the element after the ratio of fire and earth. She suddenly had a premonition of danger, and hurriedly pulled Lu Jingzhi and Tangtang over one by one, took a few steps back, and subconsciously protected them behind her. Hearing a bang, the paper that Sugar Candy used to draw the figure was blown to pieces, and a large ball of fire rushed out of the paper, revealing the canopy of the big tent, and a smell like gunsmoke permeated the surroundings, and the two little guys were also frightened into saying nothing.

"What did you do?" Tilly was no longer surprised, the two little ones were more destructive than she knew, and now she was just trying to figure out how they did it.

Lu Jingyi's face was shocked, looking at the center of the explosion point that was still smoking, his heart was filled with a feeling of excitement and fear, he pointed to the blackened ash on the ground and said, "Look...... You see, like...... Like a grenade?" Tangtang felt in his heart that this was nothing more than the power of a big firecracker, at best, it was a large firecracker, but he followed Lu Jingzhi's meaning and said: "Yes, it's like a grenade in that game, Brother Yangyang has taken me to play before." Lu Jingzhi got Tangtang's affirmation, and said happily: "What you said must be CS, I have played that game with Li Boyang and Fat Man." Tangtang was startled by the explosion just now, and couldn't muster up the interest to join Lu Jingzhi, but it was not easy to refute, so he had to deal with it: "Well, that's it." ”

Tilly looked at them singing and harmonizing, laughed in her heart, and asked Lu Jingzhi, "How did you do it?"

Lu Jingzhi spread his hands and said, "Sister Rong'er said that different colors of qi go on this map...... Tilly interrupted him: "That's a different element." Lu Jingzhi nodded and said, "Yes, different elements go ...... on the diagram" Tilly interrupted again: "It's a spell contract." Lu Jingzhi nodded again and said, "Different elements are walking around on the spell contract, and they are ...... by this figure We're called line segments, what's your name?" he didn't want to be interrupted by Tilly again, so he simply stopped and waited for her standard call. Tilly laughed when she heard this: "We also call it a line segment." Lu Jingzhi had no choice but to continue: "The line segment on this figure is to determine what elements can enter or not, the tighter the inner circle, the more concentrated the elements, and the elements of different proportions are mixed with different effects, such as the 12 parts of the earth element and the 7 parts of the fire element, which can match the same effect as nitric acid; 5 parts of the earth element and 1 part of the water element can match the effect of sulfuric acid, plus 2 parts of the life element and 1 part of the fire element, and then mix the other elements to make the effect of organic explosives." It's just that this inner ring is too fragile, if you can strengthen them a little bit and let the mixed elements accumulate a little more, the effect can be increased by a hundred times, maybe more. ”

Now this effect is no longer comparable to ordinary black powder, if it is detonated in a closed container, I am afraid that it will not only be the result of lifting off a canopy, but the entire Chinese army's tent will have to be lifted off.

Tilly ordered someone to come over and clean up the mess, and she took Lu Jingzhi and Tangtang to another place to continue talking, but it was no longer a spell, but something historical. For example, what is the relationship between the undead and the undead, how did the undead come about, and so on. If you want to know what happens next, let's see the next breakdown.
