I don't know how the two girls discussed, but Xiaomei, who has always been anxious, let Xiaoyu play first for the first time, and just like that, now it is Bobo and Supersonic Bat who are facing each other on the field.

"Ultrasonic bat, use ultrasound!" Xiaoyu is not the kind of personality to attack when she comes up, she chooses to weaken her opponent first.

"Bobo, free to play!" Free to play? What does that mean?

Don't get me wrong, given the special nature of this battle, Wang Sheng gave everyone a precautionary shot at the beginning, saying that in most cases he would let the elves decide how to act for themselves, and only when he thought it was necessary, he would give some simple instructions, so he would say this.

"Goo!" Bobo's reaction was unexpected, its body only flickered slightly, and then suddenly rushed straight towards the supersonic bat at a very fast speed, and it had no intention of dodging at all, as if it didn't care about ultrasound at all.

"Is it stupid?" Bobo's strange behavior made Xiaoyu completely confused, and Xiaomei on the side was also full of question marks, only Wang Sheng raised his eyebrows slightly, as if he had realized.

Soon, Bobo's actions had an answer. At this time, I saw that the body had contracted into a spindle-shaped wave with minimal wind resistance, and a cone-shaped shield suddenly appeared on the outside of its body, which magically blocked all the ultrasonic waves, and swept towards the supersonic bat with a huge blasting sound.

With a loud bang, the supersonic bat was knocked away alive, and then fell heavily to the ground, obviously suffering a lot of damage.

"Supersonic bat!" Xiaoyu was shocked, she didn't expect that Wang Sheng's Bobo could have such a terrifying effect with just one blow.

After waiting for a while, the supersonic bat barely flew again, but the frequency of flapping its wings was much slower, and it looked like it would be unstable when a gust of wind blows. If there is a detection instrument at this time, the scan result of the ultrasound bat is undoubtedly a red blood state, or the physical strength has been beaten to the level of single digits, and it is estimated that as long as it is touched again, it will immediately collapse.

The power of this move is too terrifying! But why don't you know which of the skills Bobo can learn has such great power? There doesn't even seem to be a similar one! Xiaoyu and Xiaomei have surprisingly the same thoughts at the moment.

At this time, Wang Sheng was already stunned by the sudden surprise, at this time, his whole body was motionless, his eyes were wide in surprise, even his breathing was a little shorter, and two words came out of his mouth: "Sound barrier!"

Sound barrier is a physical phenomenon in which an object gradually catches up with the sound waves it emits as it travels close to the speed of sound. As a result of the superposition and accumulation of sound waves, shock waves are generated, which in turn hinders the acceleration of the object's flight, and this obstacle to the speed of increase due to the speed of sound is called sound barrier. When the flying subject breaks through the sound barrier and enters the supersonic speed, it will produce a cone-shaped sound cone from the very front, which is like an explosion to the onlooker, so it is called a sonic boom or sonic boom.

Wang Sheng's cultivation direction of Bobo, speed is a very important choice and criterion, after all, Bobo's final evolution type has the ability to fly close to the speed of light, so he has not relaxed from the beginning to urge Bobo to exercise his speed, Bobo's consistent performance has not disappointed his expectations, and he is progressing with a very stable attitude. But what he never expected was that Bobo would be able to give such a beautiful report card at this time.

The high-speed flight itself can bring a huge impact, and with the effect of the upper sonic cone attacking and defending, its effect is far greater than that of a simple one plus one.

"Xiao Sheng, what kind of skill is that?How can it be so powerful?Tell me, I must let the supersonic bat learn it too!" Xiao Yu's expression was extremely excited, which was really rare for her who had always been quiet.

"And I still have me! The unicorn insect can fly after evolving to the big needle bee, and I want it to learn too!" Xiaomei also came up at the right time to join in the fun.

Wang Sheng shook his head helplessly, first told them about the sound impairment, and then explained: "Although the speed of the supersonic bat and the big needle bee is not slow, the supersonic bat can further improve its speed after evolution. But don't forget one thing, the so-called fast, there is a difference, one is the absolute speed of fast, the other is flexible, excellent maneuverability, the former is represented by a variety of flying dragons, their flight ability is definitely not weak, but the relatively large size is destined to their mobility will be a shortcoming, as for the supersonic bat and the big needle bee belong to the latter category, their strength lies in the small range of flashing and moving, belonging to the typical ...... of winning with flexibility"

"What kind of category does that Bobo belong to?" Xiao Mei interrupted him directly, she was now only concerned about whether her elf could learn this trick.

"It's not one category," Wang Sheng shook his head, "Bobo is a comprehensive type that is not weak in both aspects, and only in this way can the power of this move be brought into play." If it's the former, it's okay, they can at least learn it, but their acceleration ability is not good, and when they use this trick, the opponent will already be far away, so using it is useless. As for you, I'll just ask, are you sure that the final evolved cross-word bat of the giant needle bee or even the supersonic bat can fly at supersonic speeds?"

Speechless, or to put it more appropriately, it should be that the two girls were stunned by Wang Sheng's question. In the face of huge interests, most people will unconsciously ignore the potential problems that may arise, and they are obviously no exception this time.

Wang Sheng sighed, Bobo played a little big this time, in the face of this powerful skill, few people can resist the temptation, but fortunately, the two girls have not lost their minds, and then they have to help them more.

After making up his mind, Wang Sheng stopped grinding, and after consulting the two daughters, the battle continued.

After comparing the sound barrier time, the next battle was a bit uneventful. Wang Sheng made up his mind to help people, and the instructions he gave were more focused on guiding Xiaoyu. Just like in Go, the master plays chess to the latecomer, it seems that you come and go very lively, but in essence, the rhythm is in Wang Sheng's grasp, and Xiaoyu's performance is also worthy of affirmation, and gradually learned to use the flexibility of the supersonic bat to maneuver with the opponent, basically a lot of progress.

In the end, although Wang Sheng released water to a large extent, the accumulated advantage of the sound barrier was maintained to the end. It's just that at this time, everyone's mind is no longer on winning or losing.

Next, it's time for Xiaomei.
