"Lord Wang, the sudden explosion on the water just now was caused by the princess's fire control technique?"

Although Chang Feng asked, his eyes did not leave the scene in the waterhole that had not yet dissipated.

Although it wasn't too far away, they didn't see the movement of Ye Feiyan's hand clearly, but only saw a red orb fly out of her hand and land on the water.

"Didn't the prince already say that the princess is practicing the advanced level of the fire control technique, then the princess must have practiced it." Lan Jiang's eyes were also looking at the turbulent waterhole.

The corners of Jun Lan's mouth were crooked, his eyes had already been withdrawn from the waterhole, and he looked at Ye Feiyan who was standing there with a smile on her face, "It seems that Yan'er's fire control skills have surpassed that of the master." ”

The lotus leaves of the Ice Blood Lotus swayed with the waves of the water, enjoying the turmoil that had never been seen before.

The aquatic plants and poor fish drifting on the surface of the waterhole drifted with the waves, gradually drifting to the outlet of the waterhole, and then drifting downstream with the stream.

The surface of the water gradually returned to its original appearance, the layers of ripples formed by the falling curtain of the waterfall rippled in circles, and the lotus leaves of the Ice Blood Lotus began to sway gently with this slow ripple.

"Little girl, it seems that you have comprehended the advanced level of the fire control technique."

When the warm breath of the ancient wind rising again on the water surface came to his face, he finally came to his senses, and his mood was a little happy, a little sour, and seemed to be a little sad.

"Grandpa Feng, now I'll tell you about my method of increasing the power of the fireball, and you will definitely be able to practice the art of controlling fire to the same level as me."

After the excitement, Ye Feiyan's mood finally calmed down.

Gu Yifeng nodded, and the eagerness in his eyes changed to eagerness that he had never felt before, because he found that the power of Ye Feiyan's fire control technique was many times stronger than that of the bad old man back then.

After a cup of tea, Gu Yifeng finally threw a fireball infused with internal force into the waterhole according to Ye Feiyan's guidance.

Although the fireball he launched was not as powerful as Night Feiyan's, it was much stronger than the one he had originally launched.

"Little girl, you might see what's wrong?"

Gu Yifeng looked at the water surface that would soon return to calm, and felt a little lost in his heart.

"Grandpa Wind, have you tried to increase the size of the fireball a little more?"

"Little girl, when the fireball formed by the internal force is the size of a fist, I can't increase its size."

Ye Feiyan suddenly understood in her heart why the fireball launched by Gu Yifeng just now was one or two points smaller than her fist.

"Grandpa Feng, I feel that the reason why the power is not strong enough, one of the reasons why the fireball formed by your urging internal force is only the size of a fist, and the other reason is that you don't seem to be able to withdraw the internal force fast enough when the fireball falls."

In order not to hit Gu Yifeng, there were some words that Ye Feiyan did not say, because she clearly felt that after he injected the internal force into the fireball, it seemed that the subsequent internal force was a little difficult to control the trajectory of the fireball and the speed at which the internal force was withdrawn when it fell.

Gu Yifeng thought back to his feelings and nodded, "Little girl, I seem to have a feeling that my internal strength can't be replenished, but there is a way to solve this problem?" ”

Night Feiyan's mind flashed through the various bombs she had come into contact with in her previous life, and their power varied depending on their size.

"Grandpa Feng, if you reduce the size of the fireball and try again according to the method I said, you must remember that the wrapping force will not stop until the fireball is compressed to the point that it cannot be compressed, and stop when you feel that the fireball has an increasing momentum when the internal force is injected."

Ye Feiyan paused in his tone, and continued: "You can control the specific size, but after the fireball reaches the destination point, you must withdraw as quickly as possible

Drop the thrust and wrap force on it. ”

Gu Yifeng nodded, and began to try with a solemn expression.

After trying three times, looking at the waterhole, although the area was only one-third of the formation caused by Ye Feiyan, it was enough to compare the height of the splash, and Gu Yifeng's eyes sparkled.

"Little girl, obviously the size of the fireball is only sixty percent of the original, but the power has reached five or six times that of the original, why is this?"

Ye Feiyan's expression froze, thinking about it carefully, and she didn't know how to answer Gu Yifeng's question.

There are no balloons here, so what should she use as an example to illustrate the principle for Gu Yifeng? It's really a little hard.

Looking at Ye Feiyan, who was frowning, Gu Yifeng said loudly: "Is it because a large amount of internal force is injected into the fireball?" ”

Ye Feiyan's heart moved, and her brows relaxed, "Grandpa Feng, it is for this reason, think about it, if we use an internal force to attack a very large stone, although it will cause a certain amount of damage to it, but the damage will not be very large, but if we use ten internal forces to attack this stone at the same time, then it can produce a lot of destructive power, and even break it." ”

"Little girl, I see, it seems to have injected many strands of internal force into the fireball, and when the fireball cracked, these many strands of internal force would hit its surroundings."

Ye Feiyan nodded, "Grandpa Feng, that's the truth. ”

Seeing the scenery created by Gu Yifeng's use of fire control techniques, Jun Lan, Chang Feng and Lan Jiang were already surprised.

Looking up at the sun, which had already slid into the western sky, Jun Lan instructed Chang Feng and Lan Jiang to put the medicinal herbs into the cloth bags they brought.

And he himself walked to the side of Gu Yifeng and Ye Feiyan, who were still standing there discussing.

"Master, Yan'er, it's getting late, we should go back."

Gu Yifeng glanced at Jun Lan, and then looked up at the sunning in the west with resentment, although he still wanted Ye Feiyan to help him think of a way to increase the size of the fireball, he finally nodded.

Looking at Gu Yifeng, who was still a little lost, Ye Feiyan smiled and took his arm, "Grandpa Feng, when I finish refining the elixir that improves Xianggong's meridians and dantian, I will also refine a pill for you to improve your dantian, so that you can control and urge your internal force freely." ”

Gu Yifeng was pulled by Ye Feiyan towards Chang Feng and Lan Jiang, and when he heard Ye Feiyan's words, his eyes instantly lit up, "Little girl, you already know the reason why I can only reduce the size of the fireball to achieve that power?" ”

Ye Feiyan smiled and nodded, "Grandpa Feng, although you have sufficient internal strength in your dantian, you can't do it handily when you use it, am I right?" ”

Gu Yifeng nodded again and again, and the loss in his heart gradually dissipated.

He always thought that although his medical skills were not as good as his grandfather's, they were also excellent, but although he felt the problems of his dantian, he had no way to improve his dantian.

Thinking of this, Gu Yifeng couldn't help sighing, "Little girl, that's all Grandpa can teach you, and in the future, I can only write down the practice method for you, and you can practice it yourself." ”

After a pause, a smile appeared on Gu Yifeng's face, "However, when you learn the other techniques of controlling the five elements, you must teach your grandfather to practice, at least let me learn the art of controlling water, and I can compete with your grandfather." ”

"Okay, Grandpa Feng, let's practice together, and when we see grandpa one day, we will let him see and understand."

"Hahaha, well, look at what the bad old man is going to do to compete with me."

Gu Yifeng laughed, and the person who was a little taller than himself, handsome in appearance, taller in martial arts, and more learned in the art of controlling fire than himself, and still so young in his mind, couldn't help but feel wetness in his eyes.
