After breakfast early the next morning, Gu Yifeng went to Ye Feiyan's room to guide Ye Feiyan to continue practicing the art of controlling fire.

In order not to let Gu Yifeng feel that he was an eyesore, Junlan chose to leave and returned to his room.

As with the first practice of fire control, Gu Yifeng placed an idle candle on the table, then moved the chair next to the table one step away from the table, while Ye Feiyan put another chair under her fingertips after reaching out her arm, and placed a basin of cold water on the chair.

Gu Yifeng first took out the written paper and handed it to Ye Feiyan, and the paper was detailed on the paper that when the fingertips produced a stable small flame, how to control the movement of the internal force in the body, the internal force of the fingertips to break the small flame, and the steps and mind control methods of launching the internal force to transport the small flame after the disconnection.

Ye Feiyan was already familiar with it, and soon memorized the things on the paper.

"Little girl, now you practice disconnecting the internal force of your fingertips first, so that the little flame will fall off automatically."

Ye Feiyan stared intently at the tip of his right index finger, and according to the method that was already extremely skillful, he urged the internal force to form a small flame the size of a finger on his fingertips.

When the small flame stabilized, the mind moved, and the internal force suddenly retracted, and the small flame detached from Ye Feiyan's fingertips, because there was no external force, the small flame fluttered and fell into the water basin under her fingertips, and sank into the water with a pop and quickly extinguished.

Gu Yifeng nodded with satisfaction, "Little girl, although the speed of disconnection is a little slower, you control it very well, and then practice a few more times to speed up the disconnection." ”

Ye Feiyan nodded with a serious expression, but the excitement in her eyes grew stronger.

After five or six attempts, the small flame on the tip of the Night Feiyan's fingertips seemed to be suddenly disconnected, and it seemed to be a small sphere with weight, falling straight into the basin of water below, and the popping sound of entering the water was much stronger than the original.

Gu Yifeng was secretly surprised in his heart, in the end, it was the grandson of the bad old man, this speed was too amazing, although it was only to control a small flame, compared to the day when he controlled the fireball, it took eight or nine days to practice to this extent, it can be called a god speed.

"Grandpa Feng, how is this speed now?" There was a deep expectation in Ye Feiyan's eyes, like a child waiting for a candy reward.

Gu Yifeng rubbed her head dotingly, "The little girl's head is extremely smart, and she will be able to learn it." ”

Ye Feiyan's slightly tense face suddenly bloomed, and she smiled brightly, "Grandpa Feng, I have succeeded in disconnecting the flames!" Then it's time to practice the next level. ”

Ye Feiyan continued to raise her right hand and continued, "Grandpa Feng, what should I do next?" ”

"Little girl, next, you try to release an internal force immediately after the quick disconnection to push the small flame out."

As he spoke, Gu Yifeng moved the chair with the basin towards the table, and the candle on the table moved to the edge of the table.

Ye Feiyan raised her right hand, and her fingertips gradually formed a small flame, only to hear Gu Yifeng add: "For the first time, I only released a little push power, feel the distance after pushing it out, and then estimate in my heart how much thrust can push the small flame to the center of this candle on the table."

Ye Feiyan hummed softly, concentrating, and after quickly disconnecting the small flame, her mind urged a small internal force to quickly rush towards the small flame that seemed to be about to fall quickly.

The small flame was hit by the internal force and rushed forward.

As the distance traveled, the small flame gradually lost its forward momentum, and after the speed in the air completely disappeared, it fell straight down, and happened to fall into the inner edge of the water basin near the side of the night swallow, and slid into the water to quickly extinguish.

The corners of Gu Yifeng's mouth curved again, "Little girl, after visually measuring the distance, and comparing your heart with the push power you released, try it a second time." ”

Ye Feiyan's eyes narrowed slightly, according to the fact that after she had just broken the small flame horizontally, although she quickly urged the internal force to release the push force, she found the problem, so she began to list the range calculation formula of the parabolic motion in her heart, and calculate the corresponding thrust and projectile angle.

Ye Feiyan raised the fingers of her right hand slightly upwards to form a projectile angle that she had estimated best, and then urged the internal force to release a small flame.

After abruptly disconnecting the small flame, Night Feiyan quickly shifted her fingertips down slightly, and then quickly urged the internal force to apply the push force to the small flame that was just up to her fingertips.

Ye Feiyan's eyes sparkled, the corners of her mouth were slightly slanted, and she looked at the small flame very confidently and flew towards the heart of the candle on the table with a graceful parabola, like a meteor with a tail wing, which made her heart beat faster and her heart was surging.

The small flame fell impartially on the cotton core of the candle center, and after a moment, the center of the candle began to sway happily, as if it was energized by the sudden "shooting star".

When he saw Ye Feiyan's strange launch action, Gu Yifeng's eyes looked at the small flame launched without blinking.

The graceful trail left by the small flame as it streaked through the air seemed to flicker before his eyes, but he had already noticed that the small flame was in the heart of the candle.

Gu Yifeng half-opened his mouth, approached the table in disbelief, leaned over to look at the extraordinarily enchanting candle that seemed to be swaying, his mouth gradually closed, and the curvature of the corners of his mouth gradually expanded.

"Little girl, how did you do it?"

Whether it is practicing or attacking with the art of controlling fire, everyone chooses to shoot straight out, thinking that only in this way can it shoot the farthest distance, but when this little girl shot out for the second time just now, it can be seen that it did not exert too much thrust than the first time, but the range is almost twice as long as the first time, and the small flame falls from the sky, just falling to the center of the candle, the success rate of this ten percent of the ignition is much higher than the success rate of lighting the candle after launching straight out.

"Grandpa Feng, think about it, when the small flame flies in the air, it will definitely be resisted, just like there is no wind in the air, and when we use light power to rush forward, we feel the resistance of the wind."

Gu Yifeng nodded, as if he understood but didn't understand.

Ye Feiyan blinked her smart eyes and continued: "So if you shoot a small flame straight forward, the small flame will slowly fall under the resistance, and when you reach the candle, it may be lower than the center of the candle, so you can't light the candle. ”

"It seems that this is the reason, when we use light power, the resistance we feel when we jump forward seems to be a little less than when we go straight forward."

The corners of Ye Feiyan's mouth curved, "Grandpa Feng, that's the truth, when we use light power to jump forward, and then fall, is the forward momentum a little smaller than when we rush straight forward?" ”

Gu Yifeng's eyes narrowed, and after a moment, his eyebrows and eyes bent up, "Little girl, grandpa understands, the launch you raise your fingertips and go up obliquely is like our diagonal jump, and the process of falling in the center of the candle is like the process of landing when we want to stabilize, the smaller the momentum forward, the faster we stabilize." ”

Ye Feiyan smiled and nodded, "Grandpa Feng, this is not only labor-saving, but also has an extremely high success rate."
