"......"

Zhenyuan Shangxian stopped Tianyou from continuing, and instead asked, "What about the magic weapon I gave you?"

"Magic weapon?" Tianyou was stunned for a moment, and then remembered what Zhenyuan Shangxian said. He opened the bag, and a round ball with a surface like a silver mirror slowly floated out. "Master, but that's what you're talking about?"

This is the original Zhenyuan Shangxian to Tianyou's meeting gift, it is said that it was still refined by Zhenyuan Shangxian's senior sister, and it was also called a peerless divine soldier before the Battle of the Catastrophe. It's a pity that it was destroyed just after the refining was completed, and now there are only a few dry and painless abilities left, and it is not practical to be an ordinary magic weapon. Otherwise, it will not be put on the shelf in the worry-free bag by God.

Tianyou didn't know why Zhenyuan Shangxian suddenly thought of this thing, but he still took it out immediately.

Zhenyuan Shangxian looked at the silver sphere with a complicated look, and a ripple rippled on it, and it soon returned to calm.

After stabilizing his mind a little, Zhenyuan Shangxian opened his mouth to explain. "Although the natal magic weapon can also be used as a weapon, its real significance is not in combat, but in assisting cultivation, so the importance of the ability to refine and transmit aura is especially higher than the power. Speaking of this, he pointed to the silver sphere again, "Although this treasure has been damaged, the foundation is still there, and the power may not be as good as the complete magic weapon, but the auxiliary cultivation is far beyond ordinary treasures, and it is not even weaker than the two divine weapons in your hand." What's even more commendable is that this treasure is now in a semi-damaged state, and the effect is similar to a half-finished magic weapon, which is just enough for you to sacrifice your natal magic weapon. ”

"This ......" Hearing this answer, Tianyou was a little relieved, at least Zhenyuan Shangxian was not not helping, but had other options. But to say that to use such a half-destroyed thing as a natal magic weapon, Tianyou always has some resistance in his heart. After all, it is a natal magic weapon, who doesn't want their natal magic weapon to be a perfect peerless magic weapon? However, now they want to choose a half-destroyed magic weapon to be their natal magic weapon, how can they not be happy about this matter.

However, Tianyou also knows it in his heart. Although emotionally speaking, it is very unpleasant to use a half-crippled magic weapon to sacrifice the natal magic weapon, but in fact, just like Zhenyuan Shangxian said, the focus of the natal magic weapon is to transform the aura to assist in cultivation, and the power is not the point. In this regard alone, this half-crippled magic weapon even surpasses Taiyi and Emperor Dao, and it is indeed the most suitable natal magic weapon for him.

After thinking about it for a while, reason prevailed. Tianyou nodded and said, "Then as the master said, please help me." ”

Zhenyuan Shangxian was also very happy to hear Tianyou agree, and immediately agreed.

In fact, in the case of Tianyou, to refine the natal magic weapon is not just as simple as finding a half-finished magic weapon, but also requires the assistance of someone with sufficient cultivation. Of course, compared with the semi-finished magic weapon, this requirement is not very difficult, especially for a well-connected person like Tianyou.

Although Zhenyuan Shangxian agreed to help, it would take a very complicated process to refine the natal magic weapon beyond the deadline, so it could not be completed on the same day, and some preparations had to be made first.

Tianyou according to Zhenyuan Shangxian's request, first returned to his cave and explained to Qi Xiaomei that they take care of themselves, he has to leave for a day or two, and even the moon shadow has to stay, because there can be no interference when fusing the natal magic weapon, if the moon shadow is in Tianyou's body, it will lead to an increase in the risk of sacrifice because of the double soul.

After arranging these things, Tianyou began to rest and eat in the cave, and also adjusted the aura in his body to stabilize it. On the second day, Tianyou came to see Zhenyuan Shangxian as promised.

"Did you have a good rest yesterday? Today's fusion natal weapon requires the body to adjust to the best state, and it is best not to leave the slightest hidden danger. It doesn't matter if you wait two more days. ”

Tianyou knew that he was in good shape, so he opened his mouth to promise that there was no problem. Zhenyuan Shangxian didn't ask, so he believed him, beckoned and called the handymen to let them lift the dozen boxes in the courtyard to follow, and then took the lead out of the courtyard.

"Master, ...... this box?"

"It's all things that you need for a while, you don't have to care. ”

"So much?" Tianyou was taken aback. Yesterday, Zhenyuan Shangxian said it easily, but he didn't expect that when he went out today, it would be such a big battle, obviously Zhenyuan Shangxian was deliberately reserved, afraid that he would worry about affecting his emotions and would be more unfavorable to today's things.

Understanding Zhenyuan's intentions, Tianyou can only comfort himself and adjust his mood, after all, worrying is just to increase the trouble, anyway, the matter has come to this point, and the result will not change in the slightest.

Thinking that things would inevitably be inattentive, Tianyou calmed down a little before he realized that they had arrived at the teleportation array. The miscellaneous servants helped to pile things up on the teleportation array, but the people did not follow, and seeing that Zhenyuan Shangxian did not react, it was obvious that he had already ordered these miscellaneous servants.

Wondering where this was going, Tianyou didn't have time to ask, because when he was about to ask, the teleportation had already ended, and he happened to know the place where he came out.

"This is Zixiao Peak, Master, aren't we going to perform the sacrificial cultivation of the natal magic weapon, why are you here?"

Zhenyuan Shangxian took the lead in walking within the range of the initial teleportation array, and then explained: "Taking you to a place can increase your success rate in the first sacrifice. But although this time it is my face, I can't let you take advantage of it in vain. Isn't there still a lot of your sect's contribution value? ”

"Ah, all of them are drawn out?" Tianyou has more than one million contribution points in his hand, which is not a small amount, and he will be a little reluctant to draw them all out at once.

Zhenyuan Shangxian obviously noticed Tianyou's reaction, raised his voice a little and asked, "What?

"No, no, no unwillingness. Even the face of the master has been taken, this must be a rare opportunity, and this contribution point is definitely not worth mentioning in comparison. ”

Hearing this, Zhenyuan's attitude towards the immortals obviously recovered a lot, and he patiently explained to Tianyou while beckoning a few immortal elders here to come over to help. "We're going to go to the core secret of this sect in a moment, and you must not divulge anything about it. As a teacher, I also gave up this old face to bring you in, you have to seize the opportunity, don't let my efforts go to waste. ”

When Tianyou heard this, he hurriedly hugged his fists and said, "The disciple will definitely not live up to the master's dedication." ”

When Zhenyuan Shangxian heard this, his words suddenly changed, "If you don't want to live up to your teacher, isn't it simple? ”

"This ......"

Tianyou's current academic status in Zixiao Palace is actually in the Divine Soldier Sect, and he is not a disciple of Zhenyuan Shangxian, but only a registered disciple. The relationship between the two is higher than that of ordinary disciples, but lower than that of in-house disciples.

Zhenyuan Shangxian knew that Tianyou was a material that could be made, so he had been persevering with Tianyou, and he was always thinking about tricking him to his door. It's a pity that Tianyou has a clear plan for his future, and he is unwilling to change his religion if he lives or dies, which makes him very helpless. This is a huge Zixiao Palace, he Zhenyuan Shangxian said, who doesn't squeeze his head and turn under his door?

Seeing Tianyou like that, Zhenyuan Shangxian waved his hand a little angrily: "Forget it, don't say it, I know you don't want to." Ay...... I can't look down on others who want to enter my door, why do I fall in love with you who refuses to enter my door?"

Tianyou knew that Zhenyuan Shangxian was actually just saying that, and he wasn't really angry, so he just smiled and stayed by his side. However, seeing that a group of immortal elders next to him were helping to move things, he hurried over to help again. After all, this is something prepared for him, if it is carried by the miscellaneous servants, it will be counted, and now that the immortal elders are moving, one of his disciples can't just look at it, right? Even if he is now relying on Zhenyuan to become an immortal, he can't be like this.

Zhenyuan Shangxian didn't stop him when he saw him going to help, so he took the lead and walked out. The group left the teleportation array and soon arrived at the door of a courtyard without a plaque. The immortal chief who helped didn't even go in, just put down his things and left. Tianyou thanked him vigorously in the back and said goodbye one by one.

When the immortal elders walked away, the courtyard door happened to open, and an old man with white hair walked out of it. As soon as he passed through the door, Tianyou felt that the courtyard was shining with spiritual light, making his spiritual vision ability seem to be overexposed, and he could barely see anything clearly. And now, with the courtyard door open, he saw the old man in front of him clearly.

This old man is obviously the immortal head of the sect, and his robe obviously has the style of Zixiao Palace, but it is different in terms of material selection, and it feels not so simple, but it is very luxurious. In particular, the hair crown on this person's head, although the structure is simple, the pattern is very complicated, and the materials are also quite rare, and the naked eye can see the dazzling aura shining on it, which is obviously a great treasure. Looking down carefully, Tianyou found that this person was not only a hair crown, but also a level of treasures all over his body, but compared to these foreign objects, this person's cultivation was really terrifying. His cultivation even surpassed that of the head and Zhenyuan Shangxian, and he can be called the first person in cultivation that Tianyou has seen so far.

The old man obviously knew that they were coming, and after opening the door, he didn't say anything, and beckoned a group of gold-armored warriors from inside the door to help move the box inside. Tianyou took a sneaky look, this group of warriors was actually all monks, and the spiritual light in their bodies was shining, and they were at least cultivators in the middle of the Soul Condensation Realm Returning Yuan Period. On weekdays, the immortal elders that Tianyou met in the gate rarely cultivated so high, but there were more than a dozen of them here at once, which was really a little scary.

After Zhenyuan Shangxian came in, he saluted the old man, and then asked in a low voice, "Have you prepared the things I asked Uncle Shi to prepare yesterday?"

The old man nodded slightly, "It's already there." As he spoke, he turned to Tianyou and asked, "Is this the afterlife?"

Zhenyuan Shangxian said to Tianyou: "Come here and see Taibai Venerable." ”

Tianyou hurriedly stepped forward and saluted: "Tianyou, a new disciple of Zixiao Palace, pays a visit to Taibai Venerable. ”

"Well, it's a good seedling. Tai Bai Zun responded, and then asked: "I heard that you have a lot of insights into counting, see what is the solution to this problem?"

Although I don't know why I suddenly took the test, I see that there is no shortage of eyesight. Didn't you see that Zhenyuan Shangxian was on the side to be careful, how could Tianyou dare to offend such a big guy, of course, he was humble and took the book handed over by Tai Baizun.

The book is opened, and the page that opens happens to be a topic. Tianyou took a look, and it was still an application question, and it was not like the boring questions on the paper I did when I was a child, which seemed to be the measured data of a real application, and there were even very precise parts.

Tianyou put down the book after reading it for a while, and Tai Bai Zun on the opposite side immediately asked, "Why can't you do it or can't understand it?"

Tianyou shook his head. "The disciple is not sure. I feel that it should be able to solve it, but it needs to be calculated with the aid of paper, and the disciples may not be able to complete it by mental arithmetic alone. ”

As soon as he heard this, not only Taibai Venerable, but even Zhenyuan Shangxian was dazzled. I saw that Tai Bai Zun suddenly turned his hand and pressed against the ground, and a large piece of bluestone ground on the ground not far away instantly turned into a stone powder ground, and the degree of fine crushing was even more complete than that of the crusher. What is especially terrifying is that the area he shattered is not big or small, just six blue-striped stones, but the surrounding blue-striped stones are not injured at all. This control is even more terrifying than smashing the stones directly.

After doing all this, Tai Bai Zun acted as if nothing had happened, and said to Tianyou: "Go and break a branch, and you can write there." ”

What else can God say about it? Of course, I hurriedly wrote it.

The difficulty of the questions recorded in the books is not high, of course, this is measured by the current level of education in my Greater China region on the earth. In the Shenzhou Continent, it is almost something like Goldbach's conjecture, except for a few people who can figure it out, most people's understanding of it is limited to knowing that it is difficult.

The main content of the topic is about the construction of part of the structure of a certain building, which involves a large number of knowledge points such as solid geometry and basic physics knowledge, which should be regarded as common sense problems for Chinese citizens who have completed basic education. However, to the people of the Divine Continent, this is the Book of Heaven, an extremely profound thing, something that only a very few people can understand.

Of course, this is a real-life application question, not a flat test question designed purely to test students' theoretical knowledge, so it involves a very wide range of knowledge. Solid geometry and fundamental physics are only the basics, and a certain amount of mechanical design ability and knowledge of structural mechanics are required to complete such problems. Fortunately, what is involved is only some skin, and God bless is not completely influential, even if some places do not know the formal way to solve the problem, they can solve it with other methods around the detour.

Lying on the ground to write and draw for a long time, Tianyou finally completed the calculation, but when he looked up with the book, he found that Tai Baizun was looking at the calculation process he drew on the ground in a daze, so that he didn't know if he wanted to remind him out loud. turned his head to look at Zhenyuan Shangxian on the side, and found that he was also in a daze, and he didn't know how to open his mouth if he wanted to ask for help. Fortunately, the samurai who had finished moving the box came out to resume his life, interrupting the two of them thinking.

Waving his hand to let the golden-armored warrior leave, Tai Bai Zun looked at Tianyou with blazing eyes, and then asked, "What is the result of your calculations?"

Tianyou hurriedly replied: "If the assumption is not true, the strength of this material called Fang Tianshi is insufficient, and forced construction will lead to collapse." ”

Hearing this, Taibai Zun's eyes brightened. "Oh, tell me, is there a solution?"

"Of course there is, and there is more than one. ”

"You come one by one. ”

"The first way, and the easiest way, is to change the material directly. Since the strength of the stone is insufficient, it is necessary to replace it with a stronger material. As long as the strength is up to standard, the superstructure can be supported in this way. ”

"What else?"

"There's the second option. Instead of changing the material, it is also possible to embed a material with higher structural strength in the wall to make a keel and share most of the pressure. ”

"Anything else?" Tai Bai Zun's eyes were already about to glow, and a smile appeared on his mouth unconsciously.

Tianyou said in one breath this time: "There is a third method, using the magic circle to strengthen the strength of the material itself, or to hold up part of the weight of the superstructure, so as to ensure that the pressure does not exceed the bearing capacity of the stone itself. If none of this is possible, there is a fourth option, which is to replace the material of the superstructure or reduce the overall weight by using a perforated structure. If that doesn't work, I have a fifth option. Cable-stayed structures and transverse braces are used to replace the strength of the material with structural strength to support the weight of the upper layer. However, this method will make the finished building relatively fragile, and if the balance is broken, it may collapse in an instant. ”

"Hahahaha......" Tai Baizun suddenly touched his beard and laughed when he heard this. "Hahahaha...... God bless, are you called God Bless? Sure enough, God bless me Zixiao!Hahaha......

Tianyou is a little square, and he doesn't know why Tai Bai Zun is laughing so arrogantly. The Zhenyuan Shangxian next to him was a lot more reserved, but he was also pursing his lips and not telling him what was going on.

After laughing for a while, Tai Bai Zun finally controlled his emotions. He turned to Zhenyuan Shangxian and said, "Good life cultivation, recasting Ling Xiao is just around the corner." ”

"My nephew knows. ”

Tai Bai Zun nodded, and then pointed to the calculation formula on the ground and asked, "You came up with these calculation methods?"

Tianyou hurriedly shook his head, "This is what the disciple learned from a merchant in the Western Regions when he was a child, and it is said that it is a calculation method used by a certain overseas country. ”

Tai Bai Zun nodded, but he didn't doubt Tianyou's words. "The stones of its mountains can be used to attack jade, and it is not harmful to learn more from foreign things. If Taiyi was ...... back then? Alas...... "As if thinking of something bad, Tai Bai Zun suddenly stopped, and he could clearly feel that his mood was a little low. "Forget it, don't mention it. Since your method of calculation is a foreign thing, you should teach it to others, right?"

Of course, Tianyou didn't dare to hide his secrets, not generous, he really didn't dare. Don't look at what Tai Bai Zun said politely, but Tianyou knows that there has never been any fairness in the Shenzhou Continent. Strength is justice, and Tai Bai Zun is obviously one of the "most just" people, so Tianyou doesn't plan to know the fate of arguing with him.

However, it may be that the talent just revealed was seen by Tai Bai Zun, or he cared about his reputation and didn't want to leave a bad name for this little thing, so without waiting for Tianyou to answer, he added: "This matter is counted as your contribution to my immortal sect, and it can be converted into a contribution point to the sect, and it will never take advantage of you." ”

Tianyou hurriedly politely. "Where is Tai Bai Zun talking. It is a disciple's honor to be able to contribute to my Zixiao Palace. ”

"It's good if you can teach the method, this rule still can't be messed up, there must be rewards for merit, and the contribution of the sect still has to be issued. Saying that, he really said to Zhenyuan Shangxian on the side: "This matter will bother you." ”

"Yes, Uncle Shi. Zhenyuan Shangxian respectfully agreed, and the matter was decided.

Although I don't know how many contribution points will be given in the end, Tianyou doesn't care very much. What I just used is just some trigonometric calculations plus simple addition, subtraction, multiplication and division, which can be said to be the basis of mathematics, but not important...... It doesn't seem like a big deal. Besides, this thing is actually not completely ignorant of Zixiao Palace, the counting course that I learned after the introduction is a basic mathematical subject, which not only includes hypothyroidism, but also includes some multiplication and division operations and simple geometric knowledge. The difference with God's use is that it is not systematic enough, and the symbols and operation rules are not clear. At most, God bless them will help them perfect the calculation formula and the use of Arabic numerals.

After explaining to Zhenyuan Shangxian, Tai Bai Zun turned back to face Tianyou, and then reached out and took out a paper scroll from the cuff, which looked quite large, and it was definitely not something that could be stuffed in the sleeve, so I guess it was also a spell similar to a worry-free bag.

"I heard that you have a lot of experience in taming demon pets, and this map is given to you as a deposit for your contribution to the sect. Don't refuse to take it, put it away, and take a look at it when you have time, it will help you. ”

"Thank you, Tai Bai Venerable. ”

This time, Tai Bai Zun didn't continue to say anything else, but took Tianyou and them into the courtyard at the back.

Although Zixiao Peak is a floating mountain, except for a vacant space in the center of the top, the rest of the place is actually similar to an ordinary peak, with a staggered difference between high and low. The back of this small courtyard is against a mountain wall, and only the front is a flat land.

Tai Bai Zun led Tianyou and them through the front house and came directly to the last small building. This building is backed by a mountain wall, and it is basically built against the mountain. The two-story building doesn't look high, and the momentum is not magnificent, but Tianyou knows that there is something hidden behind it, because although the thing can be blocked, the huge aura that erupts out can't be sealed at all.

Qi Xianyou thought that it was all the aura emitted by Taibai Zun's body, but when he arrived here, he was sure that it was not the aura on Taibai Zun's body, but from a deep place behind this building. The building is supposed to be some kind of camouflaged entrance, and the part of the space behind it that penetrates into the mountain is the focus.

Tai Bai Zun didn't enter the building, but just helped them open the gate, and then waited for Tianyou and Zhenyuan Shangxian to enter before turning around and leaving.

As the outside door closed, the room was plunged into darkness. It wasn't completely dark, though, as there was still a faint blue light shining ahead. Through the blue light, a long tunnel can be faintly seen diagonally downward.

Of course, Zhenyuan Shangxian had been here, but he didn't explain, so he walked straight forward. Tianyou had no choice but to follow.

As they went deeper, the blue light in front of them became brighter and brighter, and when they finally reached the end of the tunnel and turned the corner, Tianyou was immediately shocked by the light source in front of him, and what surprised him even more was that he had actually seen this thing.
