As soon as the thunder and lightning emitted by the sand thunder bat were swallowed by the thunder and lightning in Yang Xiao's hand, it automatically returned to his sea of knowledge, and then merged into the thunder and lightning imprint.

After absorbing the foreign lightning, the lightning mark squirmed a little excitedly, and the originally somewhat dim body surface part also emitted a layer of strange thunder light, obviously the attack sent by the sand thunder bat was like some kind of food for the lightning mark, and the lightning mark seemed to be able to grow.

"This lightning mark is really not ordinary. Yang Xiao was a little surprised by this sudden situation, but it also seemed to be what he expected, he had actually discovered the abnormality of the thunder and lightning mark a long time ago, and this time he also deliberately tested it, but he didn't expect the thunder mark to be able to absorb other thunderbolts to grow, so it is possible that the thunder mark will grow as it grows, and the skills it brings to him should be greater, maybe it will be a powerful means for him to fight the enemy in the future.

Of course, Yang Xiao also thought about whether this thunder and lightning mark would be harmful to himself, but from the current point of view, it didn't look like it was going to harm himself. On the contrary, the help is greater, of course, he still has to watch out for the thunder and lightning mark in the future. This requires his strength to be improved a little more, and at that time, he will have enough ability to completely control the thunder and lightning mark by himself, otherwise it will be really uncomfortable to be controlled by this thunder and lightning mark.

"Don't worry about it for now, improving your strength is the most important thing now, if the lightning mark absorbs other lightning and can help you, it is also a means to improve your strength." After Yang Xiao thought about everything, he no longer hesitated, and took the initiative to absorb the thunder and lightning emitted by the sand thunder bat, of course, at the beginning, he first absorbed the aftermath of those thunderbolts, and then slowly tried to absorb the entire thunderbolt.

In this process, after the sand thunder bat issued several attacks, it saw that it could not do any harm to Yang Xiao at all, and it naturally had the intention of leaving in its heart. After all, if you continue to work in vain, it is simply a waste of your own spiritual power, and it is impossible to hunt and kill the human beings in front of you.

Although the sand thunder bat is of low rank, it has also produced some wisdom in the long-term hunting process, and when it sees that there is no way to take the human in front of it, it will naturally retreat and think of finding other food elsewhere.

However, Yang Xiao didn't plan to let this sand thunder bat leave, to say that the sand thunder bat originally had wings, if it flew to a high altitude, Yang Xiao couldn't do anything with it, but in this wind and sand, the sand thunder bat can only fly at low altitude, and the speed must be affected by the wind and sand, and Yang Xiao relies on a wonderful body, in terms of speed, it is not much worse than the flying sand thunder bat, or even faster.

When the sand thunder bat was about to leave, Yang Xiao of course quickly moved his body and intercepted the sand thunder bat.

Seeing this, the sand thunder bat naturally looked a little annoyed, and when it saw that it couldn't get out for a while, it frantically launched a thunderbolt attack on Yang Xiao again. However, this happened to fall into Yang Xiao's hands, and he could absorb the thunder and lightning emitted by the sand thunder bat again.

Entangled several times like this, whenever the sand thunder bat was about to retreat, Yang Xiao used his body to intercept it, although the sand thunder bat can launch a thunderbolt attack, but obviously the thunder and lightning in the body are not inexhaustible, and soon it is a little exhausted, and the thunder and lightning attack sent out is getting weaker and weaker.

At this time, Yang Xiao saw that there was not much thunder and lightning in the body of this sand thunder bat, that is to say, this sand thunder bat no longer had any use value.

When the sand thunder bat was about to run out of physical strength and spiritual power, it naturally couldn't dodge Yang Xiao's blow.

After killing the sand thunder bat, Yang Xiao checked the body of the sand thunder bat, and even dissected it and watched it, but he did not find some kind of thunder and lightning mark in the body of the sand thunder bat. In other words, the sand thunder bat can emit thunderbolts, most likely because its body structure is a little special, and the thunderbolts should have been hidden in its flesh and blood, and there is no device for emitting thunderbolts.

Yang Xiao thought about it for a while, and threw away the corpse of the sand thunder bat directly. For the rest of the day, he was still immersed in cultivation.

It took more than ten days, and Yang Xiao's first turn of the nine-turn golden body was considered to be a formal success, at this time his body was far better than before, and even at this time, he was afraid that he could use the strength of his body to hard-catch the thunder and lightning attack of the sand thunder bat.

After all, the sand thunder bat is only a low-level spirit beast, and its thunder and lightning attack is at most equivalent to the attack issued by the four or five layers of the spirit realm monk, and the four or five layers of the spirit realm monk can condense hail from the air, and the attack of the human monk is more diverse, so generally the four or five monks of the spirit realm can completely kill a spirit beast like the sand thunder bat.

After a slight estimate of his strength, Yang Xiao was still quite satisfied. You must know that the set of exercises he cultivated, the Nine Turns Golden Body is not a simple exercise, that is, it is very useful to cultivate until the Jindan period, according to the classification of exercises, human-level, earth-level, and heaven-level, the nine-turn golden body can be completely ranked at the top level of the heaven-level, otherwise, in his previous life, Yang Xiao would not have been able to use this set of exercises to directly cultivate to the Jindan realm.

In the following days, in addition to insisting on cultivation and consolidating the Nine Turns Golden Body, Yang Xiao also deliberately looked for traces of the sand thunder bat in the sand sea, because the thunder and lightning emitted by the sand bat could be absorbed by the lightning imprint, so that the thunder and lightning attack sent out by himself was enhanced, so that he could increase his strength again.

After searching for a while, he really found a few, and after successfully absorbing their thunder and lightning, he killed them.

On this day, when he was wandering in the sea of sand, he actually encountered a group of sand thunder bats next to a sand dune, densely packed, with hundreds of them, and such a scene is rare. When Yang Xiao got closer, he found that these sand thunder bats were besieging another spirit beast on the ground, only to see that the spirit beast on the ground was more than five feet tall, with a monkey-like face, but its body was extremely fat, with two extremely short wings on both sides of the body, and two extremely short legs walking in the desert, which was extremely funny and cute.

"So there's a sand beast here." Yang Xiao recognized the name of the spirit beast in front of him, speaking of which, this sand beast is the most common low-level spirit beast in the desert, this spirit beast is not very aggressive, but it has a high ability to drill into the ground in the desert, so it is not easy to catch. However, some monks managed to catch some back and keep them in captivity as a pet and for leisure time pleasure.

The sand beast in front of him has obviously been used as food by many sand thunder bats, and in such a situation, I am afraid that the life of a small person will be more than lucky.
