"Little guy, this flange flute has been in your hands for more than a year, I don't know how many of its functions you have mastered?" On the top of a rather steep cliff, Cheng Xian looked at the lock flute on Lin Song's waist, and a flash of pride suddenly flashed in his eyes, and asked.

Gently taking the lock flute off his waist, Lin Song stroked the flute, but was silent. Although he has been in charge of this flute for nearly a year, he still knows very little about its many functions, and very few can use it.

His eyes rolled slightly, and Lin Song began to carefully recall what functions were used in the process of the teacher's use of the lock edge flute.

"Select the teleportation function, refine the moon spirit function, sonic attack, sonic defense, and the hidden space in the flute..."With Lin Song's memories, the scenes of the past also flashed quickly in his mind, and the functions of the lock flute that made Lin Song amazed in the past were also called out by Lin Song one by one.

"Yes, it's rare that you can call them all. In fact, the function of the flange flute is much more than that, but it is only because we have not yet fully explored it. As he becomes more familiar with the flange flute, more and more functions will be discovered. Brushing his beard slightly, Cheng Xian exclaimed.

"Of course, that's all for later. The main thing now is to master the sonic attack of the Lockedge Flute. Your own fit with the lock flute is not bad, and with time, transcendence should be a teacher. Moreover, in the past, what you paid attention to was the cultivation of Yuan Neng and Yuan Ji, but don't forget, although you are not even a small Pu Yuan, but with the Lock Yuan flute, you are not afraid of fighting against Kun Yuan and even Qianyuan level powerhouses. ”

Taking the lock edge flute from Lin Song's hand, Cheng Xian's toes suddenly touched the ground, and his figure rose directly into the air, and then flew towards the bottom of the cliff, at the same time, his fingers lightly tapped on the lock edge flute, and in the next moment, a substantial sound wave, carrying incomparable strength, suddenly shot out from the tail of the flute.

"Boom!" With an explosion, in the valley under the cliff, a monstrous amount of dust suddenly turned up, and the huge impact force made the top of the cliff where De Lin Song was shaking violently, and the crack as thick as a wrist spread along the surface like a swimming water snake. On both sides of the valley, countless birds and birds scattered in fright with the sound of the explosion, hovering in the sky for a long time...

When the dust cleared, a large pit with a radius of nearly 100 zhang appeared in front of Lin Song's eyes with great visual impact.

"Hiss!" The terrifying destructive power directly made Lin Song gasp! Just a little at random, this chain flute could burst out with such a powerful attack against the sky, and what made Lin Song even more frightened was that this extremely powerful attack was still performed by his own teacher --- a person whose own strength had not yet reached Puyuan. If it is in the hands of other Qianyuan powerhouses like Qing Wan, then this entire continent must not be allowed to go sideways?

"As I said before, the power of the Lock Rim Flute does not depend on the strength of the person who casts it, but mainly on the fit and familiarity of the Lock Rim Flute. It can be said unceremoniously that on this continent, the only one who can use the chain flute to perform the powerful attack just now is the old man. As if he knew what Lin Song was thinking, Cheng Xian explained proudly.

"Show off!" pouted speechlessly, Lin Song muttered inwardly.

"Okay, I won't talk nonsense as a teacher, now, urge the Yuan Energy in your body to warm up the Lock Edge Flute. "Hand the lock flute to Lin Song on the side, Cheng Xiandao.

"Isn't there enough nonsense!" muttered in his heart again, Lin Song casually took the chain edge flute, and wisps of yuan could seep out from the palm of his hand, slowly moistening the lock edge flute.

Since the previous practice in the family had allowed the lock flute to establish some contact with Lin Song, this lock edge flute did not have much resistance to Lin Song, and the whole process of warmth and moistening was also extremely smooth. However, Rao is like this, Lin Song still can't help but sigh in his heart.

"What a gap!" If you want to use this flute, you have to wake it up warmly in advance, if you are fighting against others, how can you have such time?

....

After a while, when the time was ripe, Lin Song's left index finger gently blocked the second hole on the flute's body, and the remaining fingers gently tapped on the flute body, and at the same time, a wisp of Yuan Energy quietly converged between Lin Song.

With the convergence of that wisp of Yuan Energy, the lock edge flute, which had been dimmed with Cheng Xian's release, became green again under Lin Song's manipulation.

Holding the lock edge flute in his hand, he suddenly pointed to a boulder not far away, Lin Song's fingertips lightly clicked, and in the next moment, a substantial sound wave, with the sound of whistling wind, quickly flew out from the tail of the flute.

However, the seemingly powerful attack only smashed a shallow hole the size of an egg in the boulder. This kind of destruction, ordinary four-stage Pu Yuan can be unleashed, if Lin Song has not broken through to Pu Yuan, then he will naturally be quite satisfied, but with the promotion of strength, with the current level of Lin Song's seven-stage Pu Yuan, this level of attack, he is naturally not eye-catching.

"It's not even as damaging as the last time you used the Lockrim Flute, and it seems that during this time, the old man did neglect your practice of the Lockedge Flute. Seeing the damage caused by Lin Song, Cheng Xian's old face also flashed a touch of self-blame, and then poured cold water on Lin Song mercilessly.

Nodding helplessly, Lin Song clearly remembered that when he practiced the Lock Edge Flute before fighting Mo Yuan, he smashed a big tree with the thickness of a human waist into two sections.

However, although he was slightly depressed in his heart, Lin Song firmly believed that as long as he practiced diligently, this lock flute would definitely be able to become another life-saving hole card for himself after the cloud palm and swift decision.

In the mountains and forests, there was a swishing sound of breaking the wind from time to time, and with each sound, a substantial sound wave would shoot out from the tail of the lock edge flute, and then shoot at the target that Lin Song had locked in advance.

Time slipped by unconsciously, and the cold moon on the horizon also quietly climbed to the top of the East Mountain at some point. And in the mountains and forests, a tireless figure in a green shirt was still practicing diligently, but judging from the damage it caused, it seemed that it was not much different from the attack caused by the first time he used the Lock-Edge Flute.

"Take your time, you don't have to be discouraged and inferior, the old man has traveled to the mainland for so many years, and among the people he has come into contact with, there are not many people who can fit with the flute of the lock edge, and the fit can reach you like this, and only you are. In time, this flute will be in your hands, and it will be able to exert the power to destroy the heavens and the earth. And, "Brushing his beard, Cheng Xian comforted Lin Song with his own care, and was about to continue. When he raised his head, he found that Lin Song had stopped moving his hand at some point, and was looking at himself with an extremely strange look.

"What?" Lin Song's sudden move also made Cheng Xian raise his eyebrows and ask.

"Well, that, teacher, I'm not discouraged and inferior, it's you who think too much!" Cheng Xian's sudden question directly made Lin Song's head hot, and then replied recklessly.

A moment later, in the quiet mountain forest, a heart-rending cry and begging for mercy suddenly came out....
