。 "Of course I know, Du Qingsong, do you want the Northern Darkness Cold Fire? Have the ability to come and grab it! ”

With a wave of Tang Zheng's big hand, the Northern Darkness Cold Fire erupted, and the blazing tongue of fire whirred, turning into a blue-white flame robe, covering his body.

"You don't have to provoke me, I won't be fooled."

Du Qingsong shook his head coldly, his face was very calm, and said:

"I'll torture you slowly and kill you again."

Du Qingsong's face showed a touch of gloom, he raised his hand slowly, and a flying knife appeared from his fingertips, although it was only three inches long, but the edge was compelling, as if it could pierce the sky.

"As you can see, this is the Cold Moon Flying Knife Soul, a second-grade soldier-type life soul, I have been practicing my natal blood for twenty years, and after the human soul is united, my body can become a flying knife."

Du Qingsong walked towards Tang Zheng step by step and said:

"The soul of man is one, the flying knife is me, I am the flying knife, no matter how powerful your martial arts are, you can't hurt me in the slightest."

Du Qingsong's body twisted, disappeared in an instant, and the whole person turned into a flying knife, like a cold moon in the sky, blooming with a dazzling cold light.

The flying knife stretched across the void, trembling slightly, and with a bang, it suddenly shot in front of Tang Zheng's eyes.

Tang Zheng was startled, and was about to take out his sword to meet it, but unexpectedly, the flying knife shook, and Du Qingsong's body jumped out and smashed his fist into Tang Zheng's head.

Caught off guard, Tang Zheng dodged sideways, was hit in the shoulder, and suddenly felt severe pain in the shoulder bone, and the whole person retreated.

This is an extremely terrifying scene, a living person can turn into a flying knife, and in an instant, he can change from a flying knife back to a human, which is simply unpredictable.

Tang Zheng swung his sword violently and killed, a pitch-black sword, with a surging military might, mixed with the demonic energy of the emperor talisman, and killed Du Qingsong fiercely.

However, Du Qingsong's body twisted, turned into a flying knife again, and soared straight into the sky, dodging Tang Zheng's sword.

In the next moment, the flying knife fell from the sky, with a touch of cold moonlight, and slashed at Tang Zheng's heart.

Tang Zheng's face was silent, and he suddenly opened the Burning Silence Eye, and shouted:

"Flame of Silence, Burst!"

A blazing flame burst from the depths of the earth, like rolling magma, rushing towards the flying knife in the sky.

A terrifying heat wave exploded, and even a thousand-year-old refined iron would be burned into molten iron.

However, the flying knife was flexible and agile, like a flying swallow in the clouds and a catkins in the wind, flashing to the side lightly, and then attacking around the back, straight into Tang Zheng's back.

Tang Zheng hurriedly dodged sideways, and the flying knife swept over his shoulder, bringing up a splash of blood.

Tang Zheng's physique is as tough as iron and unmatched, but he was injured by a flying knife so easily, which shows how sharp the blade of the flying knife should be.

"Your martial arts are very strong, ten times more powerful than me, but unfortunately, you can't hurt me."

The flying knife twisted, and Du Qingsong's figure came out, and he stood in the distance, looking at Tang Zheng with a sneer.
