With Liu Xi's greeting in advance, no one came to disturb Liu Xi until ten o'clock the next day.

Liu Xi spent nearly twenty hours exercising the Xiao Tian Yuan Divine Arithmetic Skill, and he had been calculating the simplified version of the method of any door.

Xiao Tian Yuan Shen Arithmetic is known as one of the seven strongest arithmetic techniques in the cultivation world, which can measure good fortune and evil, know the future, feel the heavens, and so on. However, Xiao Tianyuan Shensuan's most prominent ability is to speculate on the secret of the exercises.

From the mythological period to the ancient period and then to the present modern period, the recorded history of the monastic world is at least more than 4 million years. During this period, countless inheritances were left behind, and there were countless Dharma exercises like the sands of the Ganges.

Because of the changes in the laws of the world, as well as the different types and characteristics, the exercises practiced are constantly evolving and adapting to the laws of heaven and earth at this stage.

Therefore, it is impossible for those legends to find the ancient super-grade exercises and be reborn from then on.

Because the ancient super-grade exercises often mean that they have been eliminated by the times, and they are no longer suitable for the changes in the laws of heaven and earth at this stage. If you forcibly cultivate, you will not achieve anything at least, or you will go mad and die if your dantian meridians are broken.

The truly powerful exercises in the cultivation world will never appear too early, often within nearly 10,000 years.

Even if there are exercises that have been passed down for more than 100,000 million years, those exercises must be calculated and improved at any time to adapt to the laws of heaven and earth at this stage.

For example, the Heavenly Dao Sect's Zhen Sect Exercise "Zidan Book" is the continuous improvement of each generation of Heavenly Dao Sect Sect Masters and Supreme Elders after calculation.

Almost every generation of Zidan books is different, but the power is always stronger, at least not worse than the previous generation.

Not only the sect master and the Supreme Elder, as long as they are disciples of the Heavenly Dao Sect, even if they are outer disciples, as long as they find the flaws of the "Purple Pill Book", no matter whether they propose a way to improve it or not, they will wait for the excess reward of the Heavenly Dao Sect.

Another point is that the sect masters and elders of the Heavenly Dao Sect not only calculate the improvement method of the Zidan Book day and night, but if they encounter fighting methods with other sects, demons, demons, etc., they will also learn from the other party's spells or body techniques to improve the Zidan Book.

One of the most obvious examples is the puppet formation, which is an improvement from the Wu Clan's Heavenly Puppet Technique.

Another example is the stupid chicken of Qianjimen, which was originally not a particularly amazing life-saving spell, but it was improved by countless generations of disciples of Qianjimen into an anti-heaven magic power comparable to immortal arts.

As a scholar of the Heavenly Dao Sect and a well-known knowledgeable academic talent in the cultivation world, Fairy Liu Xi's ability to calculate and improve the exercises has always been above the standard.

This time, after meditating for nearly twenty hours, the result was good, and she had already calculated a simplified version of the Arbitrary Method.

Liu Xi stood up, looked at the puddle of gravel powder on the bed, and with a flick of his hand, all the stone dust turned into a piece of wind and sand, and all flew out of the window.

has been using Xiao Tianyuan Divine Calculation, and her spiritual power and mind have been greatly consumed, not to mention anything else, she has at least consumed three jade treasures.

Liu Xi pushed open the window, and there was a bare hill opposite it, and there was a small octagonal pavilion on the top of the mountain.

Although they were at least three or four kilometers apart, Liu Xi's eyes could clearly see that there was no one in the pavilion.

Liu Xi's heart moved, took a deep look at the pavilion, and completely reflected the details of the octagonal pavilion in his mind.

Then, she suddenly stretched out her index finger, and her nails slowly turned a brilliant purple.

Liu Xi stretched out his hand to draw in the air, and the bright purple nails passed through the air, leaving a purple mark.

It's like cutting through the space, and a spatial crack is drawn.

Liu Xi drew a rectangle in the air, which looked like a door.

She reached out and pushed on the "door", then strode inside.

Suddenly, Liu Xi's figure disappeared.

The next moment, she appeared on the top of a bare hill, standing in the octagonal pavilion frowning and thinking.

The cast time is five seconds, the travel distance is about four kilometers, and the spiritual power is consumed by about one-third.

The initial improvement of the arbitrary gate was obviously ineffective, and Liu Xi estimated that the maximum travel distance might be only ten kilometers. However, if she really moved ten kilometers, the spiritual power in her body would be burned out in an instant.

Is ten kilometers far away?

Naturally, it is far away for mortals, but for people with abilities, such as Leng Shaoning, wind abilities may appear in front of you in no more than a minute.

In this case, what is the point of using any door?

Not only did he not escape, but he consumed all his spiritual power, and the gains outweighed the losses.

The cast time is also a bit slow, taking a full five seconds.

Is it to ask in a combat state, who will give you five seconds of super long time to let you slowly draw any door to escape?

If you only look at the results, the arbitrary door that Liu Xi speculated is undoubtedly very chicken.

Although it is true that it can be used to build the foundation and cultivate it, it sacrifices most of the abilities of any gate, and its practicality is not as good as directly casting it to shrink the ground into inches.

In the monastic world, once Liu Xi's arbitrary gate is used, it can be hundreds of kilometers at least and tens of thousands of kilometers at most. Come and go as you like, you can advance or retreat, it's not too convenient.

However, Liu Xi didn't think so, at least she had successfully guessed any method that could be used during the foundation building period. Then only by continuing to calculate, I believe that the distance of any door teleportation will increase significantly, and the consumption will also decrease significantly.

Of course, she definitely couldn't reach the level of being in the monastic world, and she didn't need to reach the level she had before.

Thinking about it, any door is definitely a life-saving hole card, allowing her to travel through space anywhere in her memory. If the enemy does not have the means to restrain himself, no one in the world can really threaten Liu Xi's safety.

Come out and mix, safety first.

Of course, it is good to shrink the ground into inches, and it is better to be flexible and convenient, especially in the fight, it is a good spell to dodge or chase.

But when it comes to the method of escaping, the entire cultivation world cannot find a better method than any door.

Let's say you set up a cave in an inaccessible mountain forest with food and water in it.

When you encounter danger and need to flee for your life, you can't run towards this cave with the ground shrinking into inches, right?

But if you cast any door, you will walk directly into the cave in one step, and the pursuers behind you can only stare dryly, and they can't find you if they look for death.

Any door, this is a strategic weapon!

Liu Xi decided that in such a secret base, he must completely improve the arbitrary door.

Then, she drew a door in the pavilion and stepped inside.

The air in the dormitory shook, and Liu Xi suddenly appeared in the dormitory, which immediately startled Wei Wuji and waiter Xiaohong.
