In the dim basement of the Blood Castle, Gu Xiaobai was lying on a stone platform, a broken glass bottle was lying quietly on the ground, and only an old man in the basement was looking intently at the notebook in his hand.

According to the records of Dracula's notes, the time required for the whole process is completely unknown, it may be a few days, or it may be a few years, so Wang Meike left first after Gu Xiaobai entered a coma, of course, before leaving, he used Dracula's identity to specially instruct his wife not to disturb Gu Xiaobai in the basement.

Seeing that a week had passed, Gu Xiaobai was still in a coma, and the new ability bead had been almost absorbed, but he still didn't have any signs of waking up.

Sitting quietly in front of Gu Xiaobai, in addition to making sure that Gu Xiaobai's breathing was stable, he was burying his head in the information in this basement every day, before the double ability, Dracula had also conducted a lot of research, many of which were enough to attract attention in the world, it can be seen that he was absorbed by "Xu" for a reason, although his strength is not strong, but he can be said to be handy in similar research, which is also the reason why he has always been valued in "Xu".

After confirming that Gu Xiaobai's body was fine, he was about to continue looking through the information, when a burst of golden light suddenly erupted on Gu Xiaobai's body in front of him, and at the same time as the light lit up, Gu Xiaobai's body also trembled slightly.

Although he was worried about his situation, he didn't dare to jump to conclusions, so he could only watch quietly from the sidelines.

Soon, that golden light actually drilled out of Gu Xiaobai's body, and the dense tiny electric wires almost covered Gu Xiaobai's whole body, like countless golden threads tied to his body.

Then, the thunder light that overflowed from him became louder and louder, and there was a tendency to expand, and soon covered the entire stone platform, and the expanding trend did not weaken from beginning to end.

He got up and stepped back, because the thunder light was stepping back to the entrance of the basement, and the thunder and lightning finally stopped expanding.

The sound of ......thunder and lightning made people's scalps tingle, and the golden thunder light was like a small snake, and it would be extremely painful to be drilled into the body by any of them, because this was the ability that Gu Xiaobai chose in Dracula's notes- Yang thunder, this is an ability that can produce extremely destructive thunder and lightning, as long as it is touched by any bit of lightning, ordinary people will inevitably die on the spot, even if it is a person with extraordinary abilities, it will be very painful, thunder and lightning can instantly penetrate the victim's body and directly destroy the internal organs, this kind of power has no effective way to resist, which is also the main reason why Gu Xiaobai chose it, this kind of ability has also been banned by many countries' abnormal organizations, the reason is that the pain it brings to people is too terrifying.

But the more powerful the ability, the more difficult it is to obtain it, at this time, Gu Xiaobai's whole person has been completely penetrated by Yang Thunder, the whole person is curled up, his body is C-shaped like a roasted shrimp, and at the same time he trembles violently, the saliva at the corner of his mouth and the tears at the corner of his eyes flow down together, you can imagine what kind of pain he is experiencing.

But the next scene made Gu Xiaobai's heart flutter, Gu Xiaobai's seven orifices actually began to bleed, and the blood dripped down his cheeks and fell onto the stone platform, and soon dyed a large area red.

The blood dripping from the "hiss......" was instantly evaporated by the thunder and lightning, leaving a black mark, and then fresh blood dripped and then evaporated again, and so on......

No one knows how much blood Gu Xiaobai has shed, but he knows that he has been alive, he has not died, he has survived.

On the twelfth day of the closure of the basement, the stone slab under Gu Xiaobai's body had turned completely black, but the thunder and lightning on his body had disappeared, and only occasionally could he see some drilled electric wires.

Gu Xiaobai's consciousness recovered a little, but it was still very vague, but he could already vaguely feel the white light in his consciousness, the kind old man's face.

"Grandpa......"

"Haha, meet again, what a good boy, he actually has double abilities, worthy of my Gu Xianhua's grandson?" Gu Xianhua patted his grandson on the shoulder happily.

"Grandpa, did you say I chose the right ability?"

"What's the difference between right and wrong? Any ability, if you use it well, can help you, and there is no exact answer to this choice. ”

Gu Xiaobai nodded, as grandpa said, there are no waste abilities, only waste abilities.

"I see you again, does it mean ......" Speaking of this, Gu Xiaobai became excited, seeing Gu Xianhua again meant that he could learn new tricks.

"Well, you did what I didn't do, and you deserve to be rewarded, so I'm going to teach you this trick, but before that, I'm going to explain to you that this trick is more difficult than 'Thorn Tide', you have to be mentally prepared. ”

Gu Xiaobai clearly knew that the "Thorn Tide" had not reached a proficient state until now, which was mainly restricted by the limited alien energy, which made him unable to practice many times.

"Don't worry, no matter how difficult it is, I will do my best!"

Gu Xianhua nodded, turned to look to the side, and muttered: "Our ability is related to the airflow, and the destructive power of the airflow is most affected by the volume, that is to say, if you want to maximize the destructive power of the airflow, you must find a way to compress the airflow to the smallest possible size, so that it can burst out with enough power." ”

"But at the same time, there is always a limit to the compression of the air flow, that is, it cannot be compressed endlessly, so how can we get as close to this limit as possible?"

Gu Xianhua raised his hands, and the surrounding airflow began to converge towards his palm, starting from a point in his palm, all the airflow was superimposed towards the center in a peculiar trajectory, while spiraling, it also maintained the maximum utilization of space, expanding a small sphere step by step.

Eventually, the compression of the air flow was completed, and it was a billiard-sized sphere, and because of the high compression, the reflection of the air flow inside to the light was changed, and it looked like a sparkling diamond.

Gu Xianhua threw the ball in his hand hard, and the crystal light was thrown into the air.

......A strange sound came from the air, and the ball was spinning at high speed, and the reflected light was very dazzling.

"Bang!" There was a muffled sound, the white light bloomed, Gu Xiaobai lost his vision in an instant, and then felt a fierce air flow blowing through his body, and it was at this moment that he had a feeling that his body was about to be torn apart.

Gu Xianhua pressed on his grandson's shoulder, making him open his eyes, the small ball in the air had disappeared, all this was just an illusion formed in his consciousness.

"Tell me how you feel. ”

Gu Xiaobai frowned, carefully recalled the whole process just now, and said slowly: "The way of superposition is very important, the airflow superimposed in a spatial spiral structure can maximize the compression, which is the key to great power. ”

Gu Xianhua nodded, agreed, and then said: "But there is another important point, that is, the tolerance of the ability itself to the destructive power of the air flow, which determines how much air flow can gather in the palm of your hand, which is directly related to the destructive power of this move. ”

Gu Xiaobai suddenly realized that what his grandfather said was right, if he wanted to maximize the power of this move, the compression method and the compressed air flow were two key points, and both were indispensable.

"Grandpa, what's the name of this move?"

"Spike stream. ”

“......”

He put down the notebook in his hand and walked slowly to Gu Xiaobai, he could clearly feel his breath, so he was relieved, but when he was about to turn around and return to the table, Gu Xiaobai actually opened his eyes.

"Phew, am I awake? Is this reality?"

He smiled and nodded, "Congratulations, it looks like you've succeeded." ”

Gu Xiaobai looked at his hands in surprise, and he felt like waking up from a dream. He raised his right hand and snapped his fingers lightly, and a thunderbolt was generated, coming and going quickly, and disappeared again in a blink of an eye, Gu Xiaobai simply waved his palm forward, and a bowl of thunder and lightning hit the basement wall directly, leaving a black mark on it.

"I really succeeded!" Gu Xiaobai raised both hands at the same time, and the wind in the basement was mixed with thunder and lightning for a while, so it was not lively......
