Pfff! Bang!

The large black iron sword which was slashing at the pale blue demon's claw instantly crumbled apart like tofu.

As for the black iron sword that was slashing at the pale blue demon's head, it felt as though it slashed at some indestructible leather. Not even the outer skin of the pale blue demon broke while the black iron sword was dissipated by the repelling forces from the pale blue demon.

When demons reached the class 4 realm, they couldn't be described with powerful any longer, but with terror and perfection.

"This is a class 4 demon, huh?"

Li Fuchen never wanted to use the Sect Origin Swords' black iron swords qi to kill the class 4 demon as it was unrealistic. Unless he executed the Sect Origin Swords' bronze sword qi, he might be able to damage the class 4 demon if he used all 3000 sword qi.

He simply wanted to experience the power and the combat method of the Sect Origin Swords.

As he rapidly retreated, the distance between Li Fuchen and the pale blue demon was pulled further apart. At the same moment, more than twenty high-level Heaven Dipper Realm martial artists, including plenty of peak level Heaven Dipper Realm martial artists all surrounded the pale blue demon and blasted at the demon violently. Even if the pale blue demon was a class 4 demon, it still wasn't able to lift its guard under the horrific group attacks, while its body had traces of blood.

That's right, it was just traces of blood.

Class 4 demons had rather tough defenses and in addition to its demonic qi protection, there was no way to truly break its defenses in a short period of time, unless its demonic qi was almost exhausted.

But the class 4 demon must not have the opportunity to devour any flesh or blood, if it did, its injuries would recover swiftly and its demonic qi would be gradually replenished.

Demons could be said to be the perfect combat life forms, which was something that demonic beasts and humans would never be able to match up to.

As the time elapsed, the pale blue demon's demonic qi was drastically exhausted.

Once its demonic qi reached a low level, it would be time for its death.

'My True Inferno Technique is almost breaking through to the 19th rank.'

The span between the 18th rank and the 19th rank of the True Inferno Technique was too wide. Li Fuchen might have broken through to the Heaven Dipper Realm, but the True Inferno Technique still didn't breakthrough immediately. But after some intense
