The difference in the second point is not the size of the range, but the power has become stronger, the power of the high-level Dao technique has increased several times compared to the middle-level Dao technique, take the tearing spell Dao technique as an example, the tearing spell Dao technique of the mid-level Dao technique can destroy a small area, uprooting dozens of big trees or destroying a village.

The high-level Dao Technique's Tearing Spell Dao Technique is different, once it is cast, it can call for wind and rain, fly sand and stones, and instantly become a rubble and ruins within a radius of a hundred miles.

And the legendary top-level Dao method can be overwhelming, pushing the withered and decaying, and destroying it instantly within a radius of thousands of miles, but that thing that can only be done by predecessors above the refining period, Li Changsheng didn't think too much, after all, he is at most the realm of the late stage of the transformation of gods, and the refining period is still far away, and the earth and the demon realm cannot advance to the refining period at all.

Li Changsheng tried his hand in the Blue Moon Desert, and immediately fell in love with the high-level Dao Technique's tearing spell Dao Technique, if he could have a few more such high-level Dao Techniques, I am afraid that there would be no need for any magic weapons.

However, the shortcomings of this high-level Dao technique are also obvious, such as when the initial sacrifice is refined, it takes a lot of mental power, which is why it is impossible to use high-level Dao techniques in the Yuan Infant Period, because the mental power of the Yuan Infant Stage is only less than a quarter of the mental power of the Transformation Period, and a high-level Dao technique will suck all the mental power of the Yuan Infant Stage dry, so there is no need to use Dao Techniques to kill the enemy, and he will be sucked dry by his mental power first and die.

Li Changsheng, who was a little happy and a little disappointed, returned to the tree house, originally before experimenting with high-level Dao techniques, he was ambitious and wanted to upgrade some more middle-level Dao techniques, and even create a few more high-level Dao techniques.

But now his mind has changed, the high-level Dao technique doesn't care much, but cares about the essence, after all, this kind of high-level Dao technique can only be used as a killer weapon once, and if he uses it twice in a row, I'm afraid that his mental power in the early stage of the god transformation will also be sucked dry.

In fact, the best level used in high-level Dao techniques is still in the late stage of the transformation of the gods, at least it has to be the middle stage of the transformation of the gods, after all, in the middle stage of the transformation of the gods, the mental power will be more than doubled, and the loss of those mental power will not have too much effect.

Li Changsheng has been resting for a few days, letting Hou Sheng's Yuan Ying monitor first, after all, in such a dangerous place, he must always keep his mental power full, otherwise once the danger comes, his mental power is insufficient, wouldn't it be useless to use any spell?

A few days later, Li Changsheng tried to upgrade some mid-level Dao techniques, but unfortunately he didn't succeed, either that kind of Dao technique itself could not be upgraded, or he encountered many incomprehensible things, it is estimated that if he could advance to the middle stage of the god transformation stage, these problems would be solved.

However, Li Changsheng did not give up, or was not convinced, because it was too monotonous to have only one high-level Dao technique, and the Tearing Spell Dao Technique was an offensive Dao technique, at least he needed a high-level Dao technique to escape, in case he encountered an extremely powerful enemy or danger, he had to have a high-level Dao Escape Technique to escape.

Li Changsheng now had a clear goal of Dao Technique Upgrade, and he found out all the Escape Dao Techniques of the mid-level Dao Technique to see which Escape Dao Technique was easier to upgrade.

As a result, Li Changsheng couldn't do it after more than ten days, and just when he wanted to give up, Hou Sheng's Yuanying interjected.

"Elder Brother Immortal, aren't you just looking for an escape spell that can be upgraded in a mid-level spell that is too narrow?"

"Huh, your idea is very good, Jiang is still old and spicy, and he didn't save you in vain. Li Changsheng praised Hou Sheng's Yuan Infant in a tone of praising a child, after all, looking at the thumb-sized Hou Sheng's Yuan Infant was a little awkward, and even the tone of talking to him became very childish.

"Thank you Brother Changsheng for your compliment, thank you Brother Changsheng for saving your life, I will repay you after I take it away. Hou Sheng's Yuan Ying said with a sigh.

"Well, even if you still have a conscience, if I hadn't taken you with me, the queen ant wouldn't have chased me hard. Li Changsheng said with some fear.

"Immortal elder brother Jiren has his own heavenly appearance, and the blue thunder that day killed the queen ant, otherwise I am afraid that the two of us are no longer in this world now. Hou Sheng's Yuan Ying saw the situation very clearly at that time, he just didn't expose Li Changsheng's braggaking when Yu Linglong was present, he hoped that Li Changsheng would remember this, although this kindness was not as good as Li Changsheng's life-saving grace to him.

"Okay, I hope you can't talk about the blue thunder that day in the future, and the blue crystal of the ant queen, you can't talk nonsense, you need to remember one thing now, that is, disaster comes from the mouth. Li Changsheng's threatening tone was obvious, not to mention that now Hou Sheng only had one Yuan Infant left, even if he was standing here intact, Li Changsheng also had the absolute strength to overpower him.

"Got it, I'm rotten in my stomach with these two things, and I'll never say it again. Hou Sheng's Yuan Ying lowered his little head, as if he was very aggrieved.

"Okay, it's okay to be a little forced in your heart, go and sentry to monitor the natural magic circle. Li Changsheng saw that the little old man-like Yuan Ying was depressed in front of him, and he felt very uncomfortable.

Seeing Hou Sheng's Yuan Ying leave dejectedly, Li Changsheng began to rummage through all those low-level Dao techniques, among which there were three most promising Flying Dao Techniques to upgrade, one was the Shenxing Taibao Dao Technique, one was the Phantom Technique, and the last one was the Stealth Technique, these three escape Dao techniques were very practical, if they could all be upgraded to high-level Dao techniques, they would definitely be very useful.

However, these three Dao techniques are difficult to upgrade, Li Changsheng spent more than half a month to upgrade the Shenxing Taibao Dao Technique and the Phantom Technique to a mid-level spell, and the stealth technique itself is difficult to cultivate, although Li Changsheng has now reached the stage of transforming into a god, but he is only a little proficient in the application of low-level stealth techniques.

It is very difficult to upgrade the stealth technique to a mid-level spell, it is estimated that Li Changsheng's current level is too low, and his comprehension is too poor, and it is estimated that when he cultivates to the middle stage of the god, he should be able to try to upgrade the stealth technique again.

Since far water can't quench the thirst of the near, Li Changsheng has no choice but to focus on the two previous retreat techniques, especially the Shenxing Taibao Escape Technique, at present, Li Changsheng has not only upgraded the Shenxing Taibao Escape Technique to a mid-level Dao Technique, but can even use it proficiently, it seems that only the Divine Taibao Escape Technique is the most promising to upgrade to a high-level Escape Technique.

After more than half a month, Li Changsheng finally upgraded the Shenxing Taibao Escape Technique to a high-level Escape Technique, this kind of Escape Technique that runs close to the ground is very interesting.
