Xu Yi was interested, just a matter of being a master of the numerical technique, and was interested in logarithmic problems.

As for the Huntian Sword, it was also a difficult problem in his eyes.

Since being guided by the Green Demon King that day, after he cultivated the Huntian Sword with the three domain sources, he has never been able to break through to the highest realm of the Huntian Sword - the Four Domain Sources.

The reason why Xu Yi was obsessed with the fourth domain source was because after his spiritual energy was replaced, he used the Huntian Sword to shoot out the four domain sources, but it was destroyed in an instant.

This fact proves that the Huntian Sword can derivate the fourth domain source.

The key reason why the mathematical model has not been able to achieve success is that the building of the mathematical model has not reached the point of being consistent.

Of course, Xu Yi still focused on the practice of these two sets of exercises.

The Qingyanbu escape method is something he urgently needs at the moment. It naturally took the most effort and energy, and the results achieved were the most significant. Xu Yi believed that it would not take long before he could complete the entire skeleton of the Qingyanbu.

In addition to studying martial arts, he also studied a lot of various classics and notes, including practice notes, methods of harming people, strange stories, and even geographical stories, all-encompassing and reading everything.

The second is the study of the medicinal properties of herbs.

Herbs are mainly concentrated on three kinds of medicines for refining Yuan Dan, which takes a lot of time and makes little progress.

Especially the exchange meetings of the Gongxue Society, he did not fall into the scene. Occasionally, Jing Long and Dong Qingke would also send good alchemy experts like flattery to give him a special lecture.

But alchemy itself is a practical project, and the effect is not very good by just saying it.

Xu Yi believes that once the Qingyan Step practices and breaks through the bottleneck, he can start to test the pills.

The third is to refine Yuan Dan, and he persevered in this process.

Previously, he had done a test and his limit was to refine seven pieces a day and he would become tired.

Xu Yi could not refine Yuan Dan in one day, and then fell into a state of rest without doing anything.

Therefore, he controlled the number of Yuan Dans refining every day to six, which not only ensured that his body would not fall into a period of fatigue, but also left time to do other things.

Fourthly, naturally, I have to accompany the little guy. The little guy has recovered his body and is extremely energetic. He is also a wood plant elves. In this world, many experts have emerged. Xu Yi is not at ease with Qiuwa, so he can only make three rules with him, occasionally accompany her to travel and play. During the rest of the time, he used different ways to deceive Qiuwa to practice hard. The deceptions next to him are useless, but as long as he talks about Ali, he can always inspire Qiuwa's fighting spirit.

Such four pieces divided almost all his time, and his life was calm, but Xu Yi enjoyed this tranquility quite a bit.

On this day, Xu Yi, who was stuck in the refining room for three days and three nights, suddenly roared to the sky. He threw the charcoal pen in his hand casually. A huge white paper filled with countless numbers and symbols floated in the air. After Xu Yi roared, he laughed happily again.

The roar and laughter alarmed Qiuwa and Huang Zu, and both big and small broke into the refining room.

Xu Yi laughed, "It's okay, but it's just a problem to solve. However, you two are just right here, Lao Huang, Qiu Wa, you can escape, I'll chase you, from here to Qingping."

Qiuwa clapped his hands and said, "So you want to play games, okay, Mr. Huang, we have to work hard, don't let him catch it. If you are willing to work hard, I will ask Uncle Hu Zi to give you another spiritual cultivation pill."

The ancestor Huang heard it and his soul trembled, his eyebrows and eyes burst into laughter, almost laughing out loud.

He has now basically figured out the trick. It is better to serve the young lady than to serve the young master. No matter how good the young master is, there may not be any reward. As long as the young master is happy, there will be basically benefits. As long as the young master speaks, the young master will not veto it at all.

At that moment, Huang Zu and Qiu Wa flashed out of the door at the same time. Unexpectedly, the two of them fled to the door. Xu Yi's figure suddenly appeared at the door like a slight smoke.

The two were startled and fled left and right. The next moment, Xu Yi grabbed Qiuwa with one hand and Huang Zu with the other.

Qiuwa shouted, "Not ready" and "Not counting", and Huang Zu was already shocked.

He had a sophisticated vision and knew how terrifying the escape technique that Xu Yi had just shown was. He came first, like a ghost or a charm. He really didn't know that there was such a magical escape technique in the world.

Xu Yi knew Qiuwa's temper and just as she sucked her temperament, she naturally refused to end it now, so she accompanied her for a while and deliberately lost a few tricks, which made her smile and go proudly.

Xu Yi threw a spiritual cultivation pill and Huang Zu, "This is the third one. Lao Huang, no matter how bad your qualifications are, if you accept this spiritual cultivation pill, you should replace your complete spiritual energy."

The ancestor Huang held the Praised Pill, feeling happy and ashamed. He first blamed himself without any trouble, and then made repeated promises that he would not disappoint the young master again.

After Huang Zu Qian's gratitude, Xu Yi sat down on the ground and looked at the manuscript paper that was as bright as a mountain. He was quite moved.

The beauty of mathematics lies in regularity, harmony, derivation, creation, and ultimately, it is a profound truth that permeates all things.

From the cause and the result, there is a cause and the result. As long as you master the profound rules contained in it, you can trace the cause and the result. There are thousands of ways. As expected, this is the most obvious and easy to grasp.

With only one general outline and result, he restored the light smoke step, which made Xu Yi feel the infinite mysteries of the way of numbers.

At the same time, he also strengthened his determination to continue climbing the Magnificent Avenue.

He can grasp the mystery of Qingyan Step. He believes that if it were not for the gap in power, it would not reach an unreasonable level, and the magic of Qingyan Step would be enough to overwhelm all the escape methods of the world.

This confidence does not come from the small victory against Huang Zu and Qiu Wa just now, but from the trust of logarithmism.

The numerical building built by the Light Smoke Step almost makes the escape technique infinitely close to teleportation.

For example, when someone else goes from point A to point B, the nearest way to walk is a straight line.

The way to walk the light smoke step is to pull the straight line between point A and point B into a round way, so that point A and point B are close to each other and coincide with infinitely.

This mysterious and unpredictable method is the intuitive mapping of the existence of space that the magic of mathematics can subvert.

After thoroughly studying the Qingyan Step, Xu Yi officially started the alchemy mode.

Before this, he prophetly met Meng Fu. He was going to retreat for a while, and the rest of the people arranged for the Huang Zu to block the enemy.

Xu Yi originally thought that the reason why he was unable to get started with the alchemy was because theory and practice could not be combined.

In other words, as long as he starts to refine elixirs, he will be able to quickly combine theory and practice.

But when Xu Yi started to use medicine to refine Yuandan auxiliary agents, he found that the theories he had not only could not guide practice, but the practice that failed could not lead to valuable theories. In short, the entire alchemy process was a mess.

Although he used the Green Fire Furnace and had enough Yuan Dan, he could not spare any money when he turned on the earth fire.
