Li Feng once studied the Totem Pillar in the temple and understood the Thousand-Blade Star Mark.

There are mysteries about wind strings and wind sound waves.

These two mysteries seem to be the same, but they are essentially different.

One is sound waves and the other is vocal music.

Sound waves are mainly generated by vibration, forming circles of ripples and spreading out.

Vocal music uses the shape of the sound to vibrate in space, forming various rhythms, which are blended into the wind and transmitted, each with its own subtleties.

If the mystery of vocal music and the mystery of sound waves are integrated into the sword technique, unexpected effects will definitely be produced when fighting the enemy.

Brush! Brush! Brush! Brush!...

Li Feng swung his sword again and again, driving the mysterious laws, trying to simulate the mysteries of various storms.

The sword light flickered, a strong wind suddenly rose, and the sharp sword lights spread out, leaving deep knife marks on the surrounding ground.

After swinging the knife more than a hundred times in a row, he suddenly struck out with the knife.

Peng, like an explosion of air, and like thunder vibrating, echoing in the sinkhole, rumbling and deafening.

Li Feng's eyes lit up, and he swung his sword again, flashing around in the sinkhole again and again.

Whoosh! Whoosh! Whoosh!....

Wherever he goes, he leaves behind a series of phantoms.

The light of the sword shines, continuous, and ethereal.

laugh!

The sword flashed, and a strange sharp whistling sound was produced.

This weird sharp whistling sound is like a steel knife cutting across the glass surface, which is extremely sharp and harsh, making the scalp numb and the soul throbbing.

Whoosh!

Li Feng suddenly turned around and stabbed suddenly, as if a hole had been pierced through the world.

Clang!

The strike of a knife is like the strike of silverware, touching the soul and making one unable to help but feel intoxicated.

Li Feng continuously swung the knife, and each swing of the knife would produce a different crisp sound. This feeling made him extremely excited, as if he had discovered some shocking secret.

After practicing in the tiankeng for a full day, Li Feng finally understood the true meaning of the mysteries of sound waves and vocal music.

If it weren't for his strange encounter, Li Feng might not have known that the mysteries of sound waves and the mysteries of vocal music had these two wonderful qualities.

"Although we didn't kill any foreigners on this trip, we gained quite a lot."

"Thanks to this wonderful sinkhole, otherwise I really wouldn't have known that the mysteries of sound waves and vocal music can have such wonderful effects. It's an eye-opener."

Li Feng inserted the sword into the scabbard behind him, his face turned red and he looked very excited.

After sorting out his mood, he immediately took off into the sky, flew away from the sinkhole, and headed straight for his residence.

There are still two hundred people left before he can kill a thousand aliens. He has to hurry up, find the target, and complete the task quickly. If he delays, he may not be able to explain it.

After flying thousands of miles, Li Feng returned to the cave where he lived, preparing to meditate and sort out his insights.

At this moment, four extraordinary auras flew at high speed from outside the sinkhole.

You don’t need to guess to know that it is Baili Qingshu and his friends.

But what's unusual is that when they came back in the past, they always came in groups, but this time someone seemed to have fallen behind, and one person was missing from the five.

It was the fat Tamu who didn't come back, and the four extraordinary auras were very weak, looking very embarrassed, and each seemed to be damaged.

Li Feng sat in the cave, sensing all this clearly.

"Damn you bastard, how could you meet the alien Balrogs in a place like that?"

"This guy Tamu was actually killed by them."

"Hey, there are too many Fire Demon aliens. The guy in the lead has at least the ninth level of extraordinary strength. We can't defeat them at all."

"Everyone, please heal your injuries quickly, recover a little, and leave here immediately. I'm afraid they will come after you later."

Baili Qingshu cast a weak look at the cave where Li Feng lived: "Do you want to inform Li Feng? I'm afraid he will be implicated."

"Forget it, he is so strong, he should be able to protect himself." Qin Ye shook his head.

Zhao Lan glared at Qin Ye and cursed angrily: "Qin Ye, why did you abandon Tamu? If we had persisted for a while, Tamu would not have died at all."

"You won't die?" Qin Ye looked at Zhao Lan coldly, gritted his teeth and shouted coldly: "Do you know how many reinforcements came when we were fighting the Fire Demon just now?"

"At least more than thirty Balrogs are coming. With the strength of just a few of us, can we defeat them?"

"If Tamu doesn't die, we will all be doomed."

Wenren Ziyue sighed softly: "It would be a pity to save the four of us if he dies."

"Walking between life and death is originally about dancing on the sword." Qin Ye glanced at everyone with a cold gaze.

"Do you think we are still the flowers in the greenhouse?"

"Stop dreaming and wake up."

"Traveling and training in the secret realm of death, we will encounter all kinds of desperate situations and dangers. Who can we rely on? We can only face everything by ourselves, including death."

Hearing the purple moon and the green trees, Zhao Lan fell into silence when he heard Qin Ye's words, and the atmosphere was desolate.

Because not long ago, the five of them teamed up to go out to practice and kill aliens. Unexpectedly, they encountered a group of Balrogs.

Originally, with the strength of their team, there was no problem in eating these Balrogs. Who would have thought that during the fight, the enemy suddenly called for reinforcements.

Baili Qingshu, Wenren Ziyue and the others saw that the opponent had a large number of people and saw that the situation was not good, so they quickly turned around and fled. Who expected that they were being chased madly by the opponent, and the two sides immediately started a life-and-death fight in the middle of the road.

Unfortunately, the opponent was so outnumbered that they had no upper hand at all and suffered heavy losses. In the end, Tamu, who was trapped in a tight siege, tried his best to use his strength to block the enemy before letting his team escape. However, he himself was trapped in the siege of the alien Balrogs and died.

Otherwise, their entire team will be wiped out.

At this moment, twenty or thirty fierce auras approached from the northwest at great speed, heading directly towards the place where Li Feng lived, each one filled with murderous intent.

"They are chasing them." Qin Ye was the strongest among them and also had the highest perception. He instantly noticed that there were pursuers rushing toward them.

Baili Qingshu's face was extremely ugly: "This difficult guy actually came directly to our lair."

"What should I do?" Zhao Lan said in a panic.

Qin Ye said without hesitation: "Run away quickly, otherwise you will die."

"Should we ask Li Feng for help?" Baili Qingshu asked.

Qin Ye said coldly: "Do you think that Li Feng will help?"

"Just don't add insult to injury."

Wenren Ziyue said: "At this point, you are still talking nonsense."

Qin Ye's expression changed and he growled: "Hurry up, those bastards are coming at a fast pace."

When everyone heard his roar, their expressions changed dramatically.

"Humph, none of you can escape."

"You are so brave if you dare to kill my people."

Just as they were about to flee, several roars suddenly sounded in the sky, and then they saw a large group of aliens soaring over from a short distance, covering the entire sky. There were thirty or forty people in total.

This group of aliens looks exactly like humans. Their bodies are covered with fiery red rock armor, they have horns on their heads, and their eyes are red. They all hold stone axes, scimitars and other sharp weapons, exuding a powerful aura.

The worst are all at the third level of the extraordinary, and the most powerful Balrogs have probably reached the peak level of the extraordinary.

This is a very famous alien race of fire demons in the arid land. They are naturally good at controlling fire, like to kill, and are very tough.

"They are coming after them." Qin Ye raised his head and looked at the dense numbers of figures suspended in the sky, his face a bit ashen as he said.

Baili Qingshu gritted his teeth and shouted: "Fight them."

"The opponent has a large number of people. If we fight head-on, we will definitely have no chance of winning!" Baili Qingshu said anxiously.

Wenren Ziyue gritted her silver teeth and said, "Let's fight out together."

"Can we kill them? The opponent has so many people. Once surrounded, no one can escape." Zhao Lan gritted his teeth and roared.

"I'm going to find Li Feng for help."

Qin Ye yelled: "Don't go, beg someone else in such a lowly manner, you can afford to embarrass this person, but I can't afford to embarrass him."

"Haha, none of you can escape." A sturdy Balrog holding a sickle-shaped weapon in both hands grinned and looked extremely cold.

"Give it to me, leave no one alive, destroy them all."

"Loot all their loot."

Upon hearing the leader's order, dozens of Balrogs suspended in mid-air roared, and immediately turned into streaks of light, swooping down crazily towards the group of humans below with overwhelming murderous intent.

Seeing the Balrogs coming to kill them overwhelmingly, Qin Ye pulled out the two curved scimitars behind him and shouted: "Fight."

As he spoke, his body moved, and with a whooshing sound, his whole body rose into the sky, instantly killing the Balrogs in mid-air.
