Shen Luo and Fu Donglai each urged their treasures to go deeper into the passage, collecting all the evil fog along the way like a gust of wind sweeping away fallen leaves.
In the blink of an eye, the two of them advanced hundreds of feet, and the passage ahead still seemed to have no end.
Fu Donglai raised his hand and the blood-red sword flew out of his hand. As the blood light expanded and shrank, a fierce roar came out. With a "whoosh", it turned into a black ghost king several meters tall. It fell to the ground with a "bang", and the whole passage trembled.
The Ghost King roared towards the sky, his roar was like a huge wave, stirring up a fierce gust of wind that made Shen Luo and Fu Donglai's clothes flutter wildly.
"What a powerful ghost king!" Shen Luo's eyes moved.
Judging from the might of the roar alone, the power of this Black Ghost King is definitely extraordinary, not to mention his other magical powers.
The ghost general looked at the black ghost king with deep greed in his eyes. His body swelled several times larger. The black ghost king sensed the ghost general's gaze and suddenly turned his head to look over, his eyes flashing with ferocity, as if he was about to pounce.
"Ouch, come back to me quickly!" Fu Donglai hurriedly urged the magic spell, and a black light shot out from it, wrapping around the black ghost king and turning it back into the green blood dry sword again.
"I didn't expect that the blood-stained sword in Fellow Daoist Fu's hand could also transform into a ghost king." Shen Luo asked with a moved look.
"Haha, it can't be compared with Fellow Daoist Shen's blood banner." Fu Donglai laughed and put away the blood-stained banner.
Seeing this, Shen Luo did not ask any further questions and continued to activate the Bloodthirsty Banner to absorb the dark fog in front.
After absorbing so much evil fog, the holes on the bloodthirsty banner healed quickly, and the banner became brand new again. However, the originally blood-red banner turned half black and half red, which looked quite strange.
Moreover, the repaired bloodthirsty banner did not stop devouring the dark fog, but became even more intense. Waves of strange black and red light shot out from the banner and pierced directly into the evil dark fog in front. Countless phantoms like human heads emerged from the black and red light and devoured the dark fog in big gulps.
The blood light on the banner began to become scarce rapidly, while the black light became thicker and deeper, and a powerful evil force gradually emanated from the banner.
When Shen Luo saw this scene, his expression changed slightly, but he did not stop casting the spell. He continued to urge the Bloodthirsty Banner to devour the dark fog here.
It seemed that Fu Donglai only had the Blood-Green Sword on him. He did not use any other Yin-attributed magic weapon to compete with Shen Luo for the Yin Mist. He just sat cross-legged and recovered.
After more than half an hour, after absorbing countless evil dark fog, the bloodthirsty banner finally stopped swallowing. With a "whoosh" sound, it shot out from the dark fog in front and landed in front of Shen Luo, making a cheerful and clear sound.
The flag now looked completely black, without a trace of blood. Shen Luo made a slight gesture and urged it, and a ball of extremely deep black light suddenly bloomed, as if it were real.
"call"
An extremely powerful force erupted from the Bloodthirsty Banner, and the surrounding passages began to rumble and tremble, as if unable to withstand this force.
Shen Luo was overjoyed and quickly restrained the power in the banner.
After swallowing a huge amount of evil fog, the power of the Bloodthirsty Banner increased dramatically. However, this is not a good place to test its power. Let's wait until we leave here.
The evil fog ahead has become thinner and it seems that there is not much left.
