The green-robed old man's face was also a lot more solemn, but he still didn't have any fear.

"Qingmo, I wonder if your heavy water can extinguish this flame of blood refining?"

The black dragon actually let out a sneer, and a trace of disdain flashed in his eyes.

"If it's the Red Lotus Karma Fire, I may still be a little afraid, just the flame of blood refining, not to be afraid. The black dragon named Qingmo opened its mouth and directly spewed out a dark blue water mass. The water mass flew out for dozens of meters and suddenly turned into a rushing river, crashing head-on into blood-colored flames.

The collision of heavy water and blood flame immediately triggered a violent explosion, and the terrifying shock wave caused the entire underground space to vibrate. Dark rivers surged, huge waves set off, mountain walls cracked, and boulders rolled down.

"It's now. ”

Su Wen's voice suddenly came into Han Yi's ears, Han Yi didn't dare to slack off, restrained the breath of his whole body, jumped into the underground dark river, and swam forward quickly.

The people who guard this place are obviously not that simple, and they are not as easy to deal with as Su Wen said. A peak Demon Venerable Realm's Mo Jiao, a peak Spirit Venerable Realm's monk, one is water, the other is wood, with water and wood, with the cooperation of the two, it can indeed compete with the demi-saint one or two.

Han Yi also knew that the matter of taking the treasure could not be delayed, once the other party sent a signal for help, he was afraid that the situation would immediately get out of control. What the other party said just now showed that he had a close relationship with the four major families of Tianyan City, and if the matter here alarmed the four major families, he and Su Wen would probably be buried here.

He swam like a mackerel in the dark river, swimming hundreds of meters with every stroke.

At this time, under the perception of his soul power, on the dark river, the battle between Su Wen and the green-robed old man and the black dragon became more and more intense. The three powerful forces of the law were intertwined, and the space was directly shattered, shattering countless spatial rifts.

Han Yi didn't dare to investigate carefully, and his soul power was taken back as soon as he made a slight contact. Although the green-robed old man and the black dragon cooperated well, they were still suppressed by Su Wen. After confirming this, Han Yi was relieved to speed up again, shuttling quickly through the water.

Soon, Han Yi was completely out of the range of the battlefield. It wasn't until more than half an hour later that Han Yi left the Dark River, turned into dragon wings, and flew into the air with him, speeding towards the core of Sumeru's mustard space.

"This guy is really cautious enough. Su Wen sensed that after Han Yi left the Dark River and rushed to the core of Sumeru mustard seeds with all his might, he withdrew his soul power and muttered to himself.

With a wave of her hand, the flame of blood refining set off a frenzy, suppressing the heavy water spewed out by the black dragon. The green-robed old man's face changed slightly, his hands flicked continuously, and the power of the law shot out one after another, turning into patches of blue fog barriers, and rushing into the heavy water.

As soon as the fog barrier came into contact with the heavy water, a magical scene immediately happened. The heavy water and the fog barrier quickly merged together, and the dark blue trees grew out one after another, and kept growing, but in a matter of moments, they grew into towering trees.

Each of those towering trees is like a blue crystal, crystal clear, and exudes an amazing chill.

In the blink of an eye, the towering blue crystal trees occupied most of the underground cavern, and the flames of blood refining could not incinerate it at all.

"Give me an annihilation. ”

The green-robed old man shouted angrily, waved his big hand, and the towering blue crystal tree shook at the same time, and countless blue crystal leaves flew out, carrying endless cold air, and it directly extinguished the terrifying flame of blood refining little by little.

However, seeing that the flame of blood refining was extinguished, Su Wen's face did not change. She even lazily stroked her forehead, as if she didn't put the green-robed old man and the black dragon in her eyes at all.

"Wood of Cold Water, I guess this is your strongest strength, it seems that it is nothing more than that. Su Wen said in a slightly disappointed tone, "It also made me look forward to it in vain." ”

Su Wen's words directly made the faces of the green-robed old man and the black dragon gloomy at the same time, and one person and one Jiao released a terrifying aura.

"Qingmo. The green-robed old man shouted.

"Understood. The black dragon immediately replied with a clear heart.

"Roar-" The black dragon opened its mouth and actually spit out the demon pill that he had cultivated for many years. As soon as the demon pill appeared, the dark river surged uncontrollably, the temperature in the cave suddenly began to drop, and even the blue breath and red breath could be seen intertwined in the air, as if water and fire were blending.

"Transform into a mirror, go. ”

The green-robed old man waved his sleeve robe, and a green light flew out, which was a small mirror made of jasper. The Heavenly Mirror flew to the location where the Demon Pill was, and the green-robed old man hurriedly sealed, and the Heavenly Mirror suddenly released a strange gravitational force, absorbing the Demon Pill to the back of the Heavenly Mirror and embedding it in the grooves on it.

Everything was done between lightning and flint, and the green-robed old man sneered, and formed the last seal, and the void was introduced.

"The law field, open. ”

Green patterns suddenly appeared on the surface of the Heavenly Mirror, and the mirror shone brightly, turning into a field that opened up to a huge distance of thousands of meters. The laws of the wood system in the realm soared, and flowers and trees grew out of thin air, revealing an astonishing vision.

"Hey, this is a bit interesting, with the help of the power of the demi-saint soldiers and the demon pill, open the domain of the law, although this is only a pseudo-law domain, but it is enough for you to compete with the ordinary demi-saint powerhouse. ”

"Now, do you still think that it's just that?" The green-robed old man had a majestic face, raised his hand and pointed out, and the terrifying power of the wood law instantly condensed into a golden-green arrow, and shot out with a roar.

The golden-green arrow pierced through the Blood Refining Flame with a clatter, and stabbed into the Law Realm of Su Wen, leaving a green trail along the way. It was obviously the weakest attack power of the wood attribute, but it was able to burst out with such terrifying power, directly penetrating the law realm of Su Wen, it was incredible.

Su Wen raised her eyebrows, and just as the golden-green arrow pierced in front of her, she moved her right hand and grabbed the arrow. The golden-green arrow couldn't move forward in her palm, and above her right hand, I don't know when a layer of dark red flames appeared, and the golden-green arrows were directly ignited by the dark red flames, and they were burned into nothingness in the blink of an eye.

"How is that possible?" the green-robed old man's face changed drastically, and there was a hint of horror in his eyes. That golden-green arrow, but it condensed more than half of the power of the law, otherwise it would not have directly penetrated Su Wen's law realm, but now it was actually caught by Su Wen and burned into nothingness with flames.

After seeing this scene, both the green-robed old man and the black dragon had an extremely bad feeling in their hearts. Perhaps the enemy they encountered this time was not an ordinary half-saint powerhouse.

"That guy is already in, and I don't need to play with you anymore. ”

Su Wen's right hand was raised flat, and blood-red lines spread out, covering the entire law realm. The flames of blood refining suddenly all shrank back, but the next moment an even more terrifying flame gushed out. The flames were dark red, and the moment they gushed out, all the cold water trees were burned into nothingness.

They blatantly crashed into the green-robed old man's Law Domain, causing the entire Law Realm to tremble. The Heavenly Mirror suspended in front of the green-robed old man was even more shining, as if it was unbearable.

"Not good. ”

One person and one Jiao screamed, the black dragon roared, and the water of the dark river turned into hundreds of water columns and rushed into the air, condensing into giant pythons, crashing into some dark red flames. However, before the giant pythons formed by the condensation of the river water came close to the dark red flames, they were completely evaporated by the extreme heat emitted by them, turning into white water vapor.

"Heavy water. ”

The black dragon roared, opened its mouth, and spewed out a column of water. Having seen the power of the dark red flame, it didn't dare to be careless at all, and this blow completely spewed out all the heavy water it had cultivated over the years.

As soon as the heavy water appeared, it turned into a rushing torrent and rushed into the dark red flames, which temporarily blocked the dark red flames.

Just half a breath later, the heavy water was ignited by the dark red flames, turning into a raging sea of fire.

"How is it possible? The heavy water I have refined has reached the level of sixfold, what kind of flame is this, even the sixfold heavy water can ignite?"

"You said that the flame of jealousy appeared at this moment, why don't you recognize it?" Su Wen showed a funny expression.

"Red Lotus Karma Fire. The black dragon and the green-robed old man exclaimed at the same time, revealing an expression of disbelief, "This is impossible, you have not yet reached the most holy, how can you condense the Red Lotus Karmic Fire?"

"Nothing is impossible in this world. ”

Su Wen's face suddenly turned cold, a blood-colored cross pattern appeared between his eyebrows, and a purple six-pointed star appeared in his pupils.

She waved her hand.

"Burn the heavens and refine the earth. ”

The dark red flames turned into more than a dozen giant rivers of flames and rushed away, crashing into the law realm released by the green-robed old man with the Heavenly Mirror and the Jiaolong Demon Pill, and soon enveloped the entire law realm and burned wildly.

The Law Realm was unexpectedly unable to resist the power of the Red Lotus Karma Fire, and cracks appeared on the green light mask, and the Red Lotus Karma Fire eroded from the cracks. The flowers and trees that grew in the field all withered in an instant, turning into bits of green light and disappearing.

The terrifying high temperature of the Red Lotus Karma Fire directly made the entire dark river boil, and the stone walls on both sides melted under the high temperature, turning into crimson lava and flowing downward. What's even more terrifying is that even the invisible space around it has been burned red and began to twist and wave.

The space inside Sumeru mustard is more stable than the outside space, and the wall of space is extremely difficult to break, but now under the red lotus karmic fire, almost all of them are about to be burned and melted, which shows the terrible red lotus karmic fire.

"It's not good, the power of the Red Lotus Karmic Fire is too terrifying, and the Law Realm can't resist it. The green-robed old man's face changed drastically, "Qingmo, it seems that you are going to fight hard." ”

"You and I have been guarding this place for tens of thousands of years, and we can't let people destroy it easily. The black dragon said in a deep voice, "Then let's fight hard." ”
