Okay, isn't this deliberately trying to exhaust me to death Now Yang Yingcui finally found an opportunity to ridicule me, she looked quite gloating: "Don't worry, you won't be exhausted, at most you will be tired and disabled." ”But she was joking, because I was a stonemason, and she knew that all too well.Yang Yingcui said: "Come on, open your stone discernment eye, pick it, if you win the lottery once, you will be tired sixteen times, come on" "Why bother with this slate is prepared by you in advance, isn't it clear which one is most suitable for you" I complained to her dissatisfied.But Yang Yingcui explained that these slate slabs were actually left by her predecessors many years ago, and she also groped in the waterhole for a long time before finding them.I couldn't smile bitterly, but I had to bite the bullet and try my luck, this is related to my vital interests, don't miss it.However, Yang Yingcui has any specific requirements, and the target slate should be biased towards high hardness or strong toughness, she said, both high hardness and strong toughness.This is difficult, how can there be both, but Yang Yingcui said that she doesn't care about this; Anyway, if I don't pick the right one, then I will continue to pick the useless one, and it is not her who is tired and tired, and I don't care about the mother, what is this called, I took the remaining seventeen stone slabs in my hand, carefully observed the direction of the natural lines, and tapped with the back of my knuckles from time to time, all over again, and finally I pointed to a diamond-shaped river bottom stone and said, "That's it." ”Yang Yingcui said half-incredulously: "Are you sure this is not a joke." ”Of course, I'm sure, I don't dare to say anything else, and I'm still quite sure about picking stones.Generally speaking, the surface of the river bottom stone will become smooth and round after 100,000 years of flowing water, which is the work of accumulation over time.And although I can see the traces of flowing water and years in my hand, the veins are still angular and undulating, which shows how hard it is.In addition, the distribution level of the diamond pattern can play a role in the whole tensile deformation but not easy to break, at most it will only peel off the surface layer without damaging the main body.If you want to carve on a solid stone or use it as a digging tool, I don't think there is any other stone that can compare with it except diamonds.After listening to my analysis, Yang Yingcui said excitedly: "Okay, then believe you once." ”Khan, even if I don't believe it, what can I do with myself in this kind of thing, and then of course, I put the stone slab I picked out and put it in the waterhole to test it, cough, the whole process is really indescribable, and I don't need to talk about the sin.I finally understood the reason why Yang Yingcui insisted that I do it.Obviously, after some twists and turns in the snake egg space, the Yin Snake should have an understanding of the magical ability of the pair of Yin and Yang Snakes in my body; This time I made such an arrangement, obviously to use me as a perpetual motion machine.I took hold of the staff again, and let it suck up all my strength; And every time I was so tired that I was about to faint, Koyama and Sakura would automatically turn their tails to teleport my new power again.Obviously, my excellent performance made Yang Yingcui happy, as long as I saw her eyebrows and smiles, I couldn't be angry, but although I was very tired and choked, but Yang Yingcui's ability to operate the medicine hoe was really eye-opening for me; I see that her technique is vaguely a shadow of a ghost magic, this woman is really not simple, it turns out that it is deeply hidden, and her ability is mainly reflected through the application of triangular stone slabs.I could see it a little clearly: the triangular slate seemed to be like a charger, sucking my strength out and strengthening myself, and then it was driven by a short staff to perform various functions and perform various operations.In other words, this is really a magical tool, since Yang Yingcui calls it a medicine hoe, the first thing I saw was its digging ability.But because it is triangular in shape, according to Yang Yingcui's technique, she is probably quite accomplished in the field of mathematical geometry, so the use of this "triangle" is full of tricks, and it seems that it really makes my depressed mood feel relieved all of a sudden.Broadly speaking, Yang Yingcui can use the triangle as she pleases, such as carving anchor points with sharp corners, measuring distances and drawing straight lines with corner edges, and she also uses the angles of oblique triangles from time to time to estimate azimuth angles.In addition, the triangular slate can also be erected as a drill bit to make cone-shaped holes, and to draw perfect circles, elliptical circles, and various polygonal squares.It's simply an all-powerful geometric painting instrument.It turns out that the triangle is used in this way, and I am really convinced of this woman In general, the work done by Yang Yingcui integrates detection, calculation and drawing, and the construction of geometric space.This is the full and complete application of magic from a mathematical point of view, which allows me to see a realm that I have never experienced before.Even to a certain extent, our Jiang family's usual method of making tombstones is dwarfed by Yang Yingcui's set.It can be said that Yang Yingcui's set is more systematic, more precise and meticulous.Now I'm wondering: Hasn't Wumen been focusing on playing poison and nourishing the soul, how can there be such a profound magic system, why haven't I heard my father mention a star and a half in the past, this is terrible, Dad, Yin Snake's spells I have been exposed to, but like Yang Yingcui's magic system, I think it is an extremely professional and standard field, if I can also just when I want to get into it, Yang Yingcui is calling me again: "Hurry up, don't delay my work" and then I was tired again, Stick out your tongue like a dog and be a spectator and think about your heart.In addition, all of Yang Yingcui's operations are carried out out of thin air in the cave space, not on the ground.After looking at it for a long time, I realized the mystery: in fact, this cave is not as empty as it can be seen with the naked eye, but there is a space hidden by magic.The work that Yang Yingcui did was to probe and draw a baseline, and then excavate the scope and shape of this space little by little with a medical hoe.It's like creating out of thin air on the ground, drawing a pattern, and then making a relief; It's just that from the perspective of magic, it is to make a three-dimensional sculpture that already exists stand out again, and then try to open it.Well, from another point of view, the whole process is more like searching and locating in the soil, to find a precious artifact and excavate it; Well, this seems to be more similar to tomb exploration and tomb robbery haha, Yang Yingcui is really a professional tomb robber and a professor-level intellectual.I don't know why I suddenly had such a thought.This is simply too ironic: our Jiang family is specially made "security doors" for non-humans; But Yang Yingcui's opponent is a professional tomb robber, and the thief is actually the secret place of the ancestors of the Wumen.aa2705221，，； mobile phone reading,
