After Yu Tianqi entered the Yin and Yang Polar Land with the Yin and Yang Polar Stones, he first checked the Yin and Yang Polar Stones given by the ruffian, and as Yu Tianqi expected, the Spring Spirit of the Yin and Yang Polar Regions was sealed.

"Hehe, it seems that the ruffian dragon has already prepared everything for me!" Yu Tianqi chuckled lightly and took out his original Yin and Yang Polar Stone from the ring, and the two stones were put together like a small mountain.

"In the last life, I used this yin and yang pole stone to refine an immortal weapon, I don't know what I can refine in this life!" Yu Tianqi smiled confidently, first looked at the two stones, and after thinking for a long time, Yu Tianqi began to prepare. This time, Yu Tianqi not only had to refine his own weapons, but at the same time, he also had to refine a Ding Furnace, which was a decision made by Yu Tianqi after thinking about it again and again. There are so many yin and yang pole stones, and Yu Tianqi is no longer saving.

Immediately, Yu Tianqi snorted lightly, and with a wave of his hands, the two extreme energies of the Yin and Yang Poles enveloped the two stones. However, Yu Tianqi did not rush to act, but sat down cross-legged and waited quietly. Before refining, what Yu Tianqi had to do was to rely on the Yin and Yang Polar Regions to improve the quality of these two stones.

Five days passed in a flash, and when the two stones emitted a red and blue halo, Yu Tianqi, who was sitting cross-legged, opened his eyes and looked at the two stones with satisfaction, and then, Yu Tianqi pinched his hands and directly controlled the yin and yang poles to pour into the two stones, forcibly sublimating the quality of the two stones. Of course, in this process, Yu Tianqi also forced a trace of the power of annihilation into the two stones, becoming the medium of sublimation.

In this way, Yu Tianqi concentrated on refining weapons in the Yin and Yang polar regions. The ruffian, on the other hand, left after waiting for some time at first.

Time passed day by day, and when the ruffian dragon returned, it was a month later. It's just that the ruffian dragon who came back this time seemed to be a little anxious.

"This kid has been around for a month, hasn't he come out yet!" The ruffian dragon scolded secretly, now that the Yuanding Holy Land is surging, all the bulls, ghosts, snakes and gods have appeared, and the strange treasure is about to appear, it stands to reason that Yu Tianqi should have made preparations a long time ago, but now, Yu Tianqi is good and has been hiding in the yin and yang polar regions.

Originally, the ruffian dragon wanted to enter and explore, but when it approached, he felt that Yu Tianqi had placed a ban in the Yin and Yang Polar Regions, and as long as he stepped into it rashly, he would inevitably be attacked by the Yin and Yang Polar Regions. Although the ruffian dragon was not afraid, he didn't want to disturb Yu Tianqi because of this.

"What the hell is this stinky boy doing! That stone is for him to refine, with his strength and the assistance of this Yin and Yang Polar Region, how can it take so long to not complete the refining!" The ruffian dragon was puzzled in his heart, but at this moment, suddenly dark clouds broke in the sky, and thunder rolled. The ruffian dragon saw it clearly, and the black magic thunder was rapidly condensing.

"Is this kid finally succeeding?" The ruffian dragon looked happy, and immediately retreated to the distance to keep watching, for a long time, until the dark clouds in the sky covered a radius of ten miles, the thick thunder and lightning of the bucket swept down, and their target was the center of the Yin and Yang Poles.

"Boom!"

When the first thunderbolt swept down, the whole space trembled, only to see the air, the space where the thunder and lightning passed were drawn out of a space crack as black as ink, when the thunder and lightning landed on the yin and yang poles, suddenly, the red and blue spring water instantly separated, revealing the scene inside.

The ruffian dragon looked around, only to see that at the bottom of the pool, a long sword shining with a red and blue halo was constantly rotating, and a fierce sword qi wrapped its whole body, and when the black magic thunder arrived, it was directly bombarded with the sword qi, although the sword qi was all dissipated, but the black magic thunder also weakened its power and poured directly into the sword body.

Listening to the sound of "hum", the sword body of this yin and yang pole sword trembled slightly, and then stabilized, and in the original red and blue halo, a purple-black halo shone out, obviously, this halo is the power of the black magic thunder.

"En?absorption?" The ruffian dragon frowned, and looked at the yin and yang polar sword with a strange expression, although the ruffian dragon admitted that this sword was very sharp and powerful, but it seemed that it lacked the spirit of the instrument, and it was far from the level of an immortal weapon.

"What the hell is this kid doing, didn't I find out about the spring spirit I gave him?" The ruffian dragon frowned, and was thinking about whether to enter it to remind Yu Tianqi when it happened that Yu Tianqi revealed his body from the yin and yang polar regions.

I saw Yu Tianqi standing with his hands in his hands, and glanced lightly at the Black Devil Thunder Tribulation in the sky, a smile appeared on the corner of his mouth, and then, as soon as Yu Tianqi's mind turned, the Yin and Yang Pole Sword emitted a sword roar, and flew around Yu Tianqi for a while, and then turned into a streamer, rushed straight up, and instantly disappeared into the high-altitude Black Devil Thunder Tribulation.

"En?" Seeing this scene, the ruffian dragon stared, and suddenly became a little anxious, the yin and yang pole sword has no sword spirit, and it cannot reach the strength of the immortal weapon, so rashly entering the weapon tribulation, it is likely to be destroyed, although the material of this sword is extremely hard, but the black magic thunder is not ordinary. "What the hell is this kid going to do!"

Although the ruffian dragon was worried, he did not act rashly, and in his heart, he faintly felt that Yu Tianqi would not do such a stupid thing. Sure enough, the ruffian dragon waited for a while, and then realized that something was wrong. The Yin and Yang Polar Sword rushed into the Black Devil Thunder, although it caused the entire Cloud Tribulation to be powerful, but it never stopped, obviously, the Yin and Yang Polar Sword was still able to fight against the Thunder.

However, things were unsettled and wave after wave, and just when the ruffian dragon was paying attention to the sky above, Yu Tianqi returned to the Yin and Yang polar regions. After a while, the sky in the distance gathered black magic thunder, and suddenly, the radius of a hundred miles became pitch black, lightning and thunder roared everywhere, and the whole earth trembled.

"Second Thunder Tribulation?" Seeing this, the whole person had lost his mind, the power of the first thunder was already extremely powerful, but this second thunder made the ruffian dragon feel threatened, the ruffian dragon had no doubt about the power of this black devil thunder tribulation, but he couldn't think of how a weapon that didn't even have a sword spirit could attract such a huge thunderstorm.

At this moment, after thinking about it, the ruffian dragon still couldn't think of a reason, so he gave up, and the whole person propped up a powerful defensive barrier, and quietly waited for the development of things.

As time passed, the power of this black magic thunder became stronger and stronger, not only the sky had collapsed, but even the earth was cracked. Moreover, the original purple-black thunderstorm has become black and white. The ruffian dragon saw it clearly, in this black demon thunder tribulation, there was actually the power of the power of annihilation.

"What did Tianqi do, he was going to destroy this planet?" The ruffian dragon had lost the ability to think at this moment, this tribulation cloud was still increasing, and the speed was very fast, and after this time, the tribulation thunder turned white. The ruffian dragon couldn't figure out how Yu Tianqi did it, but the ruffian dragon knew that if this thunder tribulation was swept down, the entire planet would be severely damaged or even destroyed.

"Yu Tianqi, you get out of here!" At this moment, the ruffian dragon is finally not calm, this planet, although it is not the Holy Ancestor Star, but it is also one of the few habitats of the demonic beasts, if it is destroyed like this, even if the ruffian dragon is the ancestor, I am afraid it will be difficult to explain to the entire clan.

"Hehe, Holy Ancestor, don't worry, don't worry, it's okay!" Just when the ruffian dragon wanted to skin Yu Tianqi alive, Yu Tianqi finally walked out of the yin and yang polar regions, revealing a harmless smile that wiped humans and animals, this smile made the ruffian dragon even more angry, and he had an urge to beat Yu Tianqi violently.

However, at this moment, the ruffian dragon noticed a huge Ding Furnace flying behind Yu Tianqi, this Ding Furnace was cast with Yin and Yang Pole Stones, and there was a powerful spiritual power fluctuation in it, obviously, the Yin and Yang Polar Spring Spirit was sealed in it.

"You refined two utensils?" Seeing this, the ruffian dragon finally understood everything, Yu Tianqi used the spring spirit of the Yin and Yang Polar Regions in this Ding Furnace, and this second wave of thunder tribulation was obviously coming for this Ding Furnace.

"Hehe, there are too many materials, and the opportunity is rare, so I refined two pieces!" Yu Tianqi laughed, and immediately raised his right hand lightly, sacrificing the Ding Furnace into the air, and then, with Yu Tianqi pinching out a series of magic tricks, the lid of the Ding Furnace opened, releasing a terrifying suction. Suddenly, the black magic thunders crisscrossing the sky all rushed towards the Ding Furnace, and they entered the Ding Furnace in the blink of an eye.

When the ruffian dragon saw this scene, his eyes widened, absorbing so many black magic thunders in one go, no matter how strong this Ding furnace is, it has to be fried. However, what frightened the ruffian dragon was that he thought that Yu Tianqi would accept it when he saw it, but Yu Tianqi never stopped, just sucking the black magic thunder in the air so unscrupulously.

"Crazy! this kid is crazy!" the ruffian dragon monster screamed, and instantly withdrew from the distance, at this moment he was too lazy to persuade Yu Tianqi to stop, he just kept watching the Ding furnace, waiting for it to explode.

However, the scene that the ruffian dragon expected did not appear, no matter how many black magic thunders entered it, it did not make the Ding Furnace feel the slightest bit weak, it was like a bottomless pit, greedily devouring everything.

Time passed minute by minute, and when most of the black magic thunder of Baili was absorbed, Yu Tianqi finally stopped moving, closed the top of the furnace, and then let the Ding furnace fly in the air to digest and absorb itself. Yu Tianqi, on the other hand, came to the exposed Yin and Yang Pole Sword, quickly pinched the trick with both hands, condensed the remaining small part of the powerful Thunder Tribulation around him, and sealed the Tribulation Spirit directly in the Yin and Yang Pole Sword.

"Use the thunder spirit as the sword spirit?" Seeing this, the ruffian dragon finally understood Yu Tianqi's intentions, using the robbery spirit as the instrument spirit, Yu Tianqi's idea was not bold, and the ruffian dragon had to admit that Yu Tianqi succeeded, and he also refined an unprecedentedly powerful fairy sword.
