"The most difficult step in the advanced level of the Fire Harness technique is the next step you will learn, first of all, the same as the intermediate level, after the wrapping force completely envelops the fireball, it will quickly disconnect, and at the same time of disconnecting, apply a thrust to it."

Gu Yifeng's tone paused, and the expression on his face was extremely serious, "This time the thrust is no longer the internal force released instantly, but the internal force must continue to act on the fireball and connect with the wrapping force on the fireball." ”

Ye Feiyan's eyes showed puzzlement, "Since you want to connect the thrust released with the wrapping force, why not release the thrust at the same time as the wrapping is completed, so that you can not only save the time required to disconnect, but also make the wrapping force and the thrust better connected?" ”

Gu Yifeng's eyebrows flashed, and his heart moved, all the people who practiced the art of controlling fire were practicing step by step according to the method left by their ancestors.

Everyone also agrees that since the intermediate stage has mastered the skills of fireball disconnection and thrust release, the next advanced stage should follow this step.

"Little girl, what you said seems to make a lot of sense, you and I can try this operation when you and I practice next."

Gu Yifeng raised his hand to stop Ye Feiyan who was about to try, and continued: "I'll teach you the next steps first, and then it's not too late to practice. ”

Ye Feiyan withdrew her hand and nodded.

"The thrust released later is linked to the wrapping force, as if there is a rope pulling the fireball, with the continuation of the thrust, the fireball can be launched to the destination, and then the thrust is quickly pulled, due to the rapid withdrawal of the thrust, the wrapping force will also be withdrawn with the thrust, so that the fireball suddenly loses the wrapping force and bursts."

"Grandpa Wind, you mean that the fireball will burst in an instant?"

Seeing that Gu Yifeng nodded affirmatively, Ye Feiyan's face couldn't help but glow, "Grandpa Feng, how powerful is the fireball burst?" ”

I wonder if it's more powerful than the bomb she made?

"A fist-sized fireball bursts out, and it must be no problem to injure the opponent, or it should be possible to set a house on fire."

Speaking of this, Gu Yifeng's face couldn't help but be sad, "Your grandfather can control a fireball that is slightly larger than the sum of his two fists, and he can be regarded as the best person who has advanced the art of controlling fire." ”

I don't know if the bad old man's fire control skills have gone further after these decades.

Ye Feiyan was still a little disappointed in her heart, "Grandpa Feng, is there a fireball controlled by someone who can raze that hill over there to the ground?" ”

Gu Yifeng looked at the small mountain bag that was not too big on Ye Feiyan's finger and shook his head, "As far as I know, no one has been able to practice to that extent. ”

It seems that according to the history books, the fire control technique of the one who looks almost exactly like the little girl seems to be able to do that to that extent.

"However, the power of the fireball is determined by the strength of the practitioner's internal strength, and it will also be affected by the ability to control it."

Ye Feiyan nodded, "Grandpa Feng, then you first tell me the key to controlling the internal force in the next steps." ”

Gu Yifeng nodded, and began to explain to Ye Feiyan in detail how to operate the internal force in her body, and how to continuously release the internal force to control the landing position of the fireball and the timing of withdrawing the internal force.

Ye Feiyan listened to Gu Yifeng's narration while silently rehearsing the steps of internal force operation in her mind.

While practicing in her mind, Ye Feiyan suddenly appeared in her heart the principle that the balloon burst would produce a huge impact at an instant, and she had the idea of trying it out in her heart.

; After Gu Yifeng finished explaining, he began to urge the internal force while explaining to Ye Feiyan again.

The fireball released by the ancient wind burst when it was about to touch the curtain of water diagonally opposite.

The curtain of water was blown open into scattered droplets, which fell on the surface of the water, as if it were a light rain.

"Little girl, now you can try."

When the fireball as big as a fist in her palm was wrapped by internal force, Ye Feiyan controlled her strength and injected a certain amount of internal force into the fireball.

In the next steps, Ye Feiyan followed Gu Yifeng's explanation step by step.

The fireball released by the Night Swift also landed diagonally on the opposite side of the water curtain, but when it burst open, the water curtain formed a scallop-shaped area around the fireball.

The water droplets that exploded into the air fell to the surface of the water, as if it was not a big shower, and the water waves in the waterhole were also chaotic.

Gu Yifeng looked incredulous, looking at the water curtain that had returned to normal, and then at the water surface that was trembling with waves.

"Little girl, why do you release fireballs with different power than mine?"

Ye Feiyan's face was serious, "Grandpa Feng, I'll tell you the reason for it later." ”

Judging from the power of the fireball released by himself just now, injecting internal force into the fireball can effectively increase the power.

However, she didn't dare to inject too much internal force just now, and she felt that she could increase the power of the fireball in another way.

Gu Yifeng's expression froze, but he instantly understood Ye Feiyan's intentions, so he patiently looked at Ye Feiyan and tried again with a serious expression.

Night Feiyan adjusted her position so that she was facing directly into the waterhole.

In this attempt, when Ye Feiyan urged the internal force to produce the fireball, the size of the fireball was appropriately increased, increasing to 1.5 times the original size.

When the internal force is released to wrap the fireball, the strength of the wrapping force is appropriately increased, and the strength of the wrapping force makes the size of the fireball gradually smaller.

Gu Yifeng looked at Ye Feiyan's strange operation, his mouth was half open in surprise, and his eyes were staring at the fireball in Ye Feiyan's hand without blinking, hoping to see the changes in Ye Feiyan's internal force from the fireball.

When the size of the fireball has shrunk to a certain proportion, and it feels that the wrapping force can no longer compress its size, Night Feiyan injects internal force into the fireball.

This time, Ye Feiyan did not control the amount of injection, but stopped injecting internal force when she felt that the internal force she injected had begun to make the size of the fireball tend to increase again.

In order to prevent the fireball from exploding and hurting the lotus leaves of the Ice Blood Lotus, the area where the fireball fell was still biased to the side of the waterfall.

The fireball fell below the curtain of water, three or four feet away from it, and exploded.

The splash of water falling from the curtain was instantly blasted back into the air, and the water on the surface of the waterhole splashed in all directions under the effect of the impact released by the fireball bursting.

The splash flew high in all directions, and then fell quickly.

It was as if there had been a storm, and the entire waterhole was in turmoil.

And the seven or eight lotus leaves of the Ice Blood Lotus were floating around under the frenzied water waves, but fortunately, the roots were strong enough, otherwise I am afraid they would have to be uprooted.

The surface of the water gradually calmed down, and there were scattered aquatic plants on the water, and there seemed to be many poor fish that had unfortunately died.
