After teaching this group of students, Yu Qian'an returned to his cave and continued to comprehend the rules of destruction. This time, it took him ten years to comprehend this batch of world core fragments, and his mastery of the rules of destruction reached 8.43%, which was still 1.6 percentage points away from 10%.
Yu Qian'an's world has expanded to more than 100 square kilometers. He originally thought that in the past ten years, his world could expand to 10,000 square kilometers. Unexpectedly, with the expansion of the territory, the size of the cracks and the strength of his mental power both affected the expansion of the world.
The crack was smaller than it is now, but the world at that time was still small, and the speed of absorbing mental power was slow, so the mental power passing through did not reach the limit of the crack. When Yu Qian'an's world was upgraded to ten kilometers, the demand for mental power reached the maximum value of the crack. Although the crack continued to expand later, Yu Qian'an's mental power also reached its maximum value.
Now Yu Qian'an has two things to do. One is to buy more world fragments, first increase the destruction rule to more than 10%, and then buy world fragments containing the five elements rule, improve the understanding of the five elements rule, and open more and bigger openings.
The destruction rules sealed on the seed of this world are only 10% of the destruction rules. In other words, as long as Yu Qian'an comprehends 10% of the destruction rules, the crack based on the destruction rules will no longer expand.
If you want to continue to expand the cracks, you either have to wait for your world to continue to expand and then absorb these rule shells, or you have to comprehend more rules and open more cracks to speed up the process.
Another thing is to find a way to increase spiritual power. Otherwise, at this rate, when will I be able to recruit my own clan? I can't let my clan live in a world with a radius of only 100 kilometers, right? How many people can it accommodate then?
Yu Qian'an spent another ten years in seclusion this time. More than a month passed outside. When he came to the stall selling the world core fragments in the square again, several stall owners recognized him.
This time, Yu Qian'an targeted more than a dozen fragments of the rules of destruction. He bought twenty at a time and planned not to come back to buy more later. He also planned to buy enough fragments of the five elements rules to comprehend 10%, so that he wouldn't have to come for several months or even half a year.
It cost Yu Qian'an more than 10,000 soul crystals to buy them all, which was a huge loss. After all, he only brought a few hundred thousand soul crystals in total.
Afterwards, Yu Qian'an went to the school library, where there were books on cultivating spiritual power. The worst ones could be read for free and could only be used by ordinary people for cultivation, while the best ones cost more than 10,000 soul crystals. Yu Qian'an naturally chose the best "Qianxing Jue" without hesitation.
This is a book that allows you to visualize the starry sky, feel the movement of the stars, imagine the movement of the stars in your mind, and then stimulate the brain's spiritual consciousness through special fairy energy movement routes, so that your mental power can grow rapidly.
Yu Qian'an tried to practice, and then found that if he wanted to practice this, he had to constantly observe the starry sky at the beginning. However, in the world of Wu Shi Pai, Yu Qian'an could not observe the starry sky.
In other words, the practice of this technique cannot gain the blessing of the hundred times speed of the Wu Shi Pai.
Moreover, it seems that the method of cultivating spiritual power cannot be accelerated directly by using the Wu Shi Pai. Yu Qian'an can only spend one-third of his time every day observing the stars and then cultivating his spiritual power. The rest of the time is spent on comprehending the rules and expanding his own world.
This time, one year passed in the real world, and sixty or seventy years passed in the Wu Shi Card. It was not easy for Yu Qian'an to improve his understanding of the rules of destruction to 10%. It took him almost a hundred years to achieve it.
Next is the rule of the five elements. The five elements are mutually generated and restrained. Every time Yu Qian'an absorbs a fragment of the world's core, he looks to see which of the five elements is the lowest, and then he comprehends it from the lowest one.
He continued to cultivate his mental power every day without fail. After a year of practice, Yu Qian'an felt that his mental power had increased by about 20%, which was quite good.
The area of Yu Qian'an's world finally expanded to one thousand square kilometers. Now with the understanding of the five elements rules, the size of the gap no longer restricts the expansion speed of Yu Qian'an's world. The only restriction is the amount of mental power.
Yu Qian'an was baffled. Why couldn't spiritual power be cultivated within the Wu Shi Pai? Was it because they were worried the time difference would affect the soul? Could it be that even such a sophisticated device as the Wu Shi Pai couldn't control the soul?
However, after decades of practice, Yu Qian'an's cultivation level has improved from the early stage of Taiyi Xuanxian to the middle stage, which is a considerable improvement. If it were normal practice, it would not be so fast. However, as his understanding of the rules deepened, Yu Qian'an's cultivation speed also increased a lot.
Yu Qian'an now understands the rules:
Destruction Rules: 10%
Lightning Rule: 6.61%
Gold: 5.45%
Wood: 5.36%
Water: 5.42%
Fire: 5.39%
Earth: 5.40%
Yu Qian'an felt that this second grade was not difficult. With the current improvement efficiency, Yu Qian'an's world would reach 10,000 square kilometers in five or six years. Within a hundred years, Yu Qian'an would definitely be able to expand the world to more than 100 million square kilometers. By then, he would adjust the world to balance again and recruit followers.
This speed is considered a relatively stable upgrade speed.
But for Yu Qian'an, as the class monitor, he was considered the most talented student by the teacher, but ended up being mediocre, which meant he was wrong.
Therefore, we still need to find a way to increase the speed of spiritual power cultivation.
Yu Qian'an asked the fat man, "Do you know any way to improve your mental strength?"
Fatty: "Increase spiritual power? I heard that the fastest way to increase spiritual power is to recruit followers and transform them through the power of faith. So generally, you increase the world area as quickly as possible, and then recruit scrolls to cultivate faith."
Yu Qian'an: "How big of a world do you usually start recruiting followers?"
Fatty: "This needs to be at least one square kilometer..."
Yu Qian'an: "How much?"
Fatty: "Boss, you don't have to worry. Although one square kilometer is difficult, it can be achieved by slowly improving it over several decades. Once your mental strength becomes stronger, the improvement speed will be faster."
Yu Qian'an looked at his world of over a thousand square kilometers and asked, "So, by the time you graduate from second year, what size will the world typically be?"
Fatty: "This should be at least one hundred square kilometers, and some more powerful ones can reach hundreds of square kilometers, and some can even reach thousands of square kilometers.
"Oh, Boss, how big is your world now? Since you're so powerful, it should be as big as a palm, right?"
