The old ghost is also familiar with the Heavenly Demon Secret Record, and naturally knows very well how to refine the Demon Head or Demon King, and Yang Tian doesn't need to worry about it at all!

Yang Tian also smashed all the mental power crystals he had collected before into the Seven Treasure Refining Demon Tower, although the quality was very low, but it was better than nothing, let the old ghost make do with it for the time being!

After arranging the old ghost, Yang Tian took out the Black Demon Sword, Xuanyu Crystal, and Spirit Weapon Dan Furnace, and prepared to start refining again!

With Yang Tian's current cultivation, he has a spiritual weapon Dan furnace, and it is not too difficult to refine a low-grade earth weapon, but he is not at all sure if he wants to refine a medium-grade earth weapon!

However, Yang is naturally bold, he likes to challenge the limit, and even dares to enter the Black Wind Canyon, not to mention trying to refine a medium-grade earth weapon, or not refining, and he has to do his best as soon as he practices, how to say that now he also has sixty or seventy thousand Xuanyu spars as a backing, and he can afford to waste it!

The selection of the large array of the earth weapon magic weapon is much wider, and there are all attributes in the five elements, Yang Tianshen thought about the electric turn, and began to screen the large array in his memory!

In Yang Tian's view, the flying sword is used to kill the enemy, of course, what is needed is attack power, the stronger the better, and the power of the selected formation is best to be super destructive, just like the kind that turns the sky over the seal!

Among the five elements array, the fire system attack is the strongest, however, the destructive power of the thunder system derived from the five elements is even better than that of the fire system, Yang Tian first screened the thunder system array!

There are also a lot of thunder arrays, but Yang Tian feels that there are a lot less to master, so he chooses and chooses, and finally decides to challenge the limit and make the formation the 'Kunyuan Chengtian God Thunder Array'!

The power of the Kun Yuan Chengtian Divine Thunder Great Array ranks in the middle and upper ranks among the great arrays of the earth weapon level, Yang Tian is not only interested in this, but more importantly, this large array can add magical spells to it!

The general large array, it is absolutely impossible to accommodate another talisman formation, even if it is forcibly added, the power of the formation does not increase but decreases, the gains outweigh the losses, the magic arrays that can add supernatural powers are very few, and they are even rarer when they are reduced to the thunder array, so as soon as Yang Tian found out about the Kunyuan Chengtian Divine Thunder Array, he immediately chose it!

Familiarizing yourself with the formation is still the first step, although the formation has become more advanced, but there is no need to spend a lot of time practicing as before, Yang Tian is now drawing the talisman in the air, although it has not yet reached the level of a rune, but as long as the thought is not withdrawn, the talisman array will not dissipate, and there is enough time to imprint into the flying sword!

After getting familiar with the formation, he took away the divine thoughts in the Black Magic Sword and threw it directly into the Spirit Weapon Dan Furnace, however, using the flame power of the Spirit Weapon Pill Furnace to refine the magic weapon of the earth weapon was already a little insufficient, and the Black Magic Sword had no signs of melting for a long time!

Yang Tianyi gritted his teeth and directly entered the True Yuan into the Dan Furnace, feeling that this should increase the power of the flames!

Rumble!

Sure enough, as soon as Zhenyuan entered, the flames in the Dan furnace immediately underwent a qualitative change, and their power increased suddenly, and the color of the flames turned into a faint gold, and the black magic sword began to melt in an instant!

"Huh? Could it be that the flame fueled by the True Yuan is already very close to the True Fire of the Immortal Family......"

Yang Tian's eyes lit up, and when he was puzzled, he felt a little incredible!

Yang Tian had seen the power of the Samadhi True Fire, and felt that the flames in the Dan Furnace in front of him were somewhat similar to them, and the power seemed to be quite close, but he hadn't even formed a human immortal golden pill, how could the True Yuan give birth to the true fire that the Triple Dan Tribulation Human Immortal could have?

"Could it be that I have taken the Polar Wood Holy Fruit, or maybe it is the amplifying effect of the Spirit Weapon Pill Furnace......"

Yang Tian secretly guessed that there were only these two possibilities, but he faintly felt that the first possibility was greater!

While waiting, the Black Magic Sword gradually melted into a black liquid, which was mixed with a trace of yellow light, which was the molten Xuanyu spar melt, Yang Tian continued to smelt, and used the true yuan to peel off the Xuanyu spar solution in it, it must be purified and cleaned, and no one can be left, otherwise it will interfere with the power of the large array!

In order to prevent the spar melt from not being enough, Yang Tian also put thousands of Xuanyu spars into it at the same time to refine them together!

When the two melts were all extremely pure, and he was sure that there was no trace of impurities, Yang Tian withdrew the true element, rolled up the black magic sword melt with mana, and cooled and shaped it in the void, perhaps it was difficult to forget Bai Ming, the shape of the black magic sword at the moment was no different from the previous Bai Ming, but it was bigger!

When the flying sword is slightly stabilized, the mana will immediately roll up the spar melt, and draw it in the void as the Kun Yuan Chengtian God Thunder Array, but at this moment, it is also necessary to add a magic spell!

"Kun Yuan Chengtian God Thunder Array, let me see where your limit is......"

Yang Tianshen thought for a moment, and he didn't know which tendon was wrong, and at the same time, he smashed the three rays of water, fire, and wind, which had been condensed and succeeded, into the big array, and then printed them into the sword body together!

At this moment, Yang Tian also became nervous, and when he withdrew his mana, his eyes stared at the floating flying sword for a moment!

Airplanes!

With a clear sound, the large array inside the flying sword finally began to operate, but with the flash of light, the flying sword suddenly trembled slightly, as if it was experiencing great pain, this was the unstable situation of the large array within the sword body!

"Huh? What's going on? Could it be that the energy of the Great Array is insufficient? ”

When Yang Tian was puzzled, according to his previous experience in refining Bai Ming, he directly threw the True Yuan into the sword!

But as soon as Zhenyuan entered, the flying sword trembled more and more, and the large array within it seemed to have a tendency to collapse!

"Convergence...... How so? ”

Yang Tian finally couldn't help it, his mana probed into the flying sword, and he was immediately shocked to find that the three divine powers were actually merging with each other!

"Will there be a miracle?"

Yang Tian began to look forward to it again, wanting to see what would happen if the three divine power runes were fused together, and Zhen Yuan continued to enter!

Airplanes...... Airplanes......

At the same time as the flying sword vibrated violently, blue, red, and black began to appear on it, and three dazzling electric lights began to appear on it, entangled and fighting with each other, exuding a terrifying and destructive momentum!

Yang Tian was so frightened that he immediately withdrew his hand and retreated, only watching from a distance, just kidding, once these three magical powers exploded at the same time, the power should definitely not be underestimated!

Whether it is success or failure, Yang Tian is powerless at this time, so he can only wait quietly!

Finally, the three lightning rays on the flying sword suddenly disappeared, and the sword body stopped trembling at the same time!

"Finally a ......"

Yang Tian was just about to breathe a sigh of relief, but the next moment, his complexion immediately changed greatly, and he flashed out!

Rumble!

With a roar, a huge sword light bolt suddenly flashed out and slammed into the ground!

Rumble!

There was another explosion, Yang Tian's scalp immediately went numb, and his heart ached, and that terrifying sword light directly blasted the Spirit Weapon Dan Furnace!

Sonor!

Along with the scattered fragments of the Dan Furnace, the flying sword actually fell to the ground!

"Damn, it's still a failure after all, even if the three divine power runes are destroyed, it's okay, and a spiritual artifact Dan furnace is set up......"

Yang Tian cursed fiercely, stepped forward to pick up the flying sword, and the next moment, ecstasy flashed on his face!

"It worked...... It worked......"

Yang Tian shouted happily, he didn't expect that the three divine power runes were really perfectly fused together in the Kunyuan Chengtian Divine Thunder Array, this was simply a miracle!

The pill gushed out, and Zhen Yuan threw it into the sword at the same time, Yang Tian couldn't wait to see the power of the new Bai Ming!

Long......

Just when Yang Tianzhen Yuan was about to die, Bai Ming was finally full of energy, and with a wave of his hand, the terrifying power immediately surged out!

"It surpasses the medium-grade earthware, and it can be regarded as a high-grade earthware......"

Although it is not as good as the Heaven Turning Seal, it will never be much worse, Yang Tian is sure that with the current cultivation to urge, it will not be weaker than Wan Shaoyang's Blood Transformation Divine Sword!
