Yang Zongyan left a few people to guard against Wang Changsheng and others, and brought others back to help Yang Zongwang.

Wang Ruyan sacrificed a cyan flying shuttle, carrying her and Wang Changsheng towards the distance, accompanied by ten second-order flying puppets.

Seeing this formation, other people naturally did not dare to stop it.

"Husband, we must find the whereabouts of that black dragon as soon as possible, otherwise, when Senior Yang frees up his hands, that third-tier monster dragon may not fall into our hands."

Wang Ruyan said with some worry.

Wang Changsheng nodded, took out two bloody black scales, patted the spirit beast bag, and the double-eyed mouse came out of the spirit beast bag.

"Remember this smell, find it."

Wang Changsheng handed the bloody black scales to the double-eyed mouse. The double-eyed mouse sniffed it lightly. Wang Changsheng fed it two century-old ginseng.

He has trained the Shuangtongshu many times, and the Shuangtongshu will lead him to find the third-order black flood dragon.

After eating two centuries-old ginseng plants, the double-eyed mouse quickly climbed onto Wang Changsheng's shoulders, sniffing the air a few times with its nose.

It screamed, Wang Ruyan stopped quickly, and flew to the left, the double-eyed mouse kept screaming, and flew to the right, it didn't scream, obviously, there was a smell of black dragons on the right.

It didn't take long for them to disappear into the sky.

Three days later, a blue light quickly passed over a certain continuous mountain range, and not long after, the blue light landed on a hill.

After the blue light dissipated, the figures of Wang Changsheng and Wang Ruyan were revealed.

A few tens of feet away from them, there is a cave several feet high.

The double-eyed mouse jumped off Wang Changsheng's shoulders, flicking its tail back and forth, as if it was very excited.

Wang Changsheng bent down and picked up a few pieces of gravel. There were some brown blood stains on them. If he didn't observe carefully, he might not have found it.

"The black flood dragon should be hidden here, lady, let's make it quick."

Wang Changsheng released two second-order ape puppets and walked in front. He put the double-eyed mouse back into the spirit beast bag, took out the ice dragon flag, and followed.

The cave was winding, and the gravel on the ground was stained with brown blood. Wang Changsheng became more and more sure that the black flood dragon was hiding here.

After walking more than a hundred steps, the road ahead became narrow, and a few black scales were scattered on the ground.

After turning left and walking straight for more than a hundred steps, a cave the size of an acre appeared in front of Wang Changsheng and Wang Ruyan. A huge black flood dragon was lying on the ground, most of its body was bloodstained and its breath was weak.

"Roar!"

Seeing Wang Changsheng and his wife, the black flood dragon rushed over immediately. Although it exploded its demon core, it was still a third-rank monster. Two foundation-builder cultivators dared to attack it, and they were looking for death.

Wang Ruyan raised his hand, and two fire thunders flew out, and when they got close to the black dragon, they burst open.

"Boom!"

Two deafening bangs sounded, and a large cloud of red flames and a large cloud of thunder covered the figure of the black flood dragon.

This is not over yet, Wang Ruyan sacrificed two second-tier middle-grade golden thunder charms.

The two Golden Lightning Talismans exploded and turned into a large piece of golden lightning.

Wang Ruyan sacrificed a few more golden talisman seals, which turned into a huge golden light curtain, covering the area shrouded in golden thunder.

The surface of the golden light curtain is covered with Buddhist runes, which are the second-rank top-grade Vajra Trapped Spirit Talismans.

The Vajra Trapping Monster Talisman is a simplified version of the third-tier formation, the Vajra Trapping Demon Array, and its defense power is far superior to that of the ordinary second-tier top-tier formation talisman.

Wang Changsheng sat down cross-legged, and took out a treasure talisman with blue light flowing all over the body, with a knife pattern painted on the surface of the talisman.

When he left Qinglian Mountain, he left the flying needle talisman to Wang Mingjiang, and he carried this flying knife talisman with him.

They dared to look for the black flood dragon, so they had something to rely on.

The mana in Wang Changsheng's body was poured into the small knife talisman crazily, and the talisman suddenly became brighter.

Wang Changsheng's magic power is deeper than that of monks of the same level. After he entered the fifth floor of the foundation building, he activated the talisman very quickly.

To be cautious, Wang Ruyan took out the top-grade magic weapon Fengweiqin, holding a Burning Blood Pill in her hand.

At this time, the golden thunder light also dissipated.

The black flood dragon was severely injured, the demon core exploded, and was injured by two self-explosive instruments and the second-order thunder talisman, and his aura became more and more sluggish.

"Roar!"

Its eyes turned blood red, and a thick black beam of light spewed out from its mouth, hitting the golden light curtain in a flash.

The golden light curtain shook violently, and the light dimmed a lot.

The black flood dragon shook its head and tail, and slammed into the golden light curtain fiercely.

There was a loud noise, the ground shook violently, and the light of the golden light curtain became dimmer.

The black flood dragon took advantage of its physical body, and after hitting it four times, the golden light curtain shattered.

At this time, Wang Changsheng was about to activate the talisman, and the blade came out without the handle.

Wang Ruyan had already taken the Fenxue Pill, and her cultivation quickly increased from the fourth floor of the foundation building to the ninth floor of the foundation building, and her jade finger quickly slid across the strings.

A rush of zither sounded, and a blue sound wave swept out, hitting the black flood dragon in a flash, but did not cause much damage to it.

Wang Ruyan raised her jade hand, and three second-rank high-grade demon bunch talismans flew out, turning into three giant yellow hands several feet in size, and pressing the black flood dragon to the ground.

"Roar!"

A dragon chant sounded, the black flood dragon flew up with all its strength, and three big yellow hands shattered one after another.

"cut."

An ice-cold voice suddenly sounded, and a two-foot-long flying knife that emitted a dazzling blue light flew towards it. With a flash, it came to the black flood dragon and slashed at its head.

It was badly wounded a long time ago, and was injured by Wang Ruyan's Huo Lei Zi and Jin Lei Talisman, and its defense had long since deteriorated.

With a scream, the head of the black flood dragon was cut off by the blue flying knife, and the headless corpse fell from midair, a large amount of blood gushed out, staining the ground red.

After beheading the black flood dragon, the cyan flying knife blurred and turned into a cyan talisman with dim light.

With a sound of "噗嗤", this talisman burned automatically and turned into ashes.

In order to kill the black flood dragon in one fell swoop, Wang Changsheng exhausted the power of the talisman at once, and the talisman was scrapped.

Wang Changsheng heaved a sigh of relief when he saw Heijiao's body, and put away the Earth Escape Talisman clasped in his hand.

They have already prepared two sets of plans. If Fu Bao can't kill the black flood dragon, they will withdraw immediately. Fortunately, they killed the black flood dragon smoothly.

Wang Changsheng and Wang Ruyan walked quickly towards the corpse of Heijiao, their faces were full of ecstasy.

A third-order flood dragon is worth more than 100,000 spirit stones. Unfortunately, the most precious demon pill is gone.

With the body of this third-order flood dragon, Wang Changsheng can refine the magic weapon of his life.

They quickly peeled off the black flood dragon's skin, cut off its claws, split it into multiple pieces, and put them into multiple storage bags.

After doing all this, the sequelae of the Fenxue Pill occurred, and Wang Ruyan was unable to use mana for half a year.

Both Wang Changsheng and Wang Ruyan knew this.

Wang Changsheng took out an earth escape talisman, crushed it with a pinch, and the husband and wife escaped into the ground and disappeared under a burst of dazzling yellow light.
