The two of them went straight to the largest stone room in the center, and Tang Ze was immediately attracted by the scene. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

This stone room is square, three zhang high, two zhang on the ground, one zhang underground, and is engraved with complex red runes in all directions, faintly forming dozens of circles. In the center of the stone chamber, there is a huge circular pit, which is also covered with red runes.

The contents of the stone chamber were simple, except for a pile of materials, only a futon, and a pennant painted with flames and hedrons.

Cheng Baikun introduced: "There are a total of six three-grade magic arrays in this refining room, all of which are 'three-three flow fire', horizontal and vertical, reciprocating, circulating, and extremely easy to control. If it weren't for these formations, Xiao Lao'er would not have been able to refine the four-grade treasure weapon. When he said this, there was a hint of arrogance on his face, he glanced around, then looked at Tang Ze, and said solemnly, "Fourth prince, please keep quiet when I refine the magic weapon." In addition, if you can't stand the heat later, you can activate this cold jade. ”

He concedes that his refining method is a secret transmission of the master, and without a special fire control decision, others will not be able to learn it at all. In addition, the heat wave was like a tide when refining weapons, and it was difficult for ordinary people to resist, so where did they still have the heart to pay attention to his refining techniques. So he wasn't afraid of others stealing it

Cheng Baikun glanced at Tang Ze again, and thought to himself: "Let this kid see the old man's methods, and give him some lessons by the way, so as to dispel his idea of wanting to learn refining weapons." The seeds of Confucianism's reading, reading to nourish qi is the right way, what kind of instrument to practice. ”

"This is natural, and the teacher is relieved. ”

Tang Ze nodded in agreement, took the cold jade handed over by Cheng Baikun, and sat down cross-legged in the corner on the side.

Cheng Baikun's face was solemn, there was no expression on his face, he came to the pile of materials on the side, took out a piece of stainless steel covered with blood lines, and then sat down on the futon in front of the round pit, and then took out several materials from the storage ring and put them aside for later use, he thought for a moment, took out a wooden box again, opened it, and revealed a piece of red metal that was more than an inch long by the size of his fingers.

It was a pure, impurity-free Xuanyang meteorite!

And Tang Ze also recognized that the piece of steel covered with blood lines was the famous god blood steel of Da Zhou!

Divine blood crossbows, divine blood armor, divine blood arrows, etc., these utensils are all made of divine blood steel.

Although it is called Divine Blood Steel, it is actually just a special steel made of demon beast essence blood, mixed with 100 steels in a special way, and calcined, which can be regarded as an artificially manufactured grade material.

There are high and low grades, mainly depending on the level of the demon beast essence blood used to forge the god blood steel. The piece of divine blood steel used by Cheng Baikun is densely covered with blood lines, and at a glance at the grade, you can know that it is at least above the second grade.

Cheng Baikun first closed his gaze, and after a while, he opened his eyes, and the red true qi around his body surged, and at the same time, he grabbed the flame order flag next to him and continued to pour true qi into it. Above the flag, flames suddenly rose up!

And the 'three- and third-rate fire arrays' on the four walls also flashed with crimson light at this time, and along the lines composed of runes, they continued to converge towards the central round pit.

Just when the crimson lines were about to gather in the middle, Cheng Baikun suddenly waved the command flag, and there was a "boom" in the void above the round pit, and a flame ignited out of thin air.

The temperature in the stone chamber suddenly more than doubled as the flame ignited, and it continued to rise as hundreds of Kun Ling flags waved.

Tang Ze was immediately under the smoking of this heat, the sweat in his body had already evaporated before he had time to flow out, and even the heat was still invading his body, he was slightly taken aback, and hurriedly grasped the cold jade that Cheng Baikun gave him, and at the same time ran the aura in his body, and then returned to normal.

Even so, Tang Ze's gaze still didn't take a slighter.

I saw that Cheng Baikun's face did not change at all, and he seemed extremely focused. He waved the order flag with his right hand, grabbed the piece of divine blood steel with his left hand, and threw it directly, and the divine blood steel froze in the void, and then was wrapped in flames and calcined. Immediately afterward, he threw the Xuanyang Meteorite over again, splitting out a flame and calcining. The two do not interfere with each other.

As time passed, the Divine Blood Steel slowly became red, and began to drip down with molten steel, and then it was bound in the void by Cheng Baikun, and a third flame was summoned, wrapping it and removing the impurities in it.

Cheng Baikun had been repeating this process all along, and after more than half an hour, the piece of divine blood steel the size of a human head had completely turned into molten steel, and only a small half of its original volume remained. And that Xuanyang meteorite iron was still only slightly red, and it obviously took more time to melt it.

Then, the molten steel of the Divine Blood Steel was wrapped in flames and moved aside, maintaining the heat while continuing to refine the impurities in it.

Three flames floated up and down in the center of the stone chamber, burning fiercely, emitting a terrifying temperature.

Tang Ze was secretly frightened, not only because the flame could easily burn his body into black ashes, but also because of Cheng Baikun's own terrifying strength, not to mention, just the means shown by the other party to be multi-minded and not affect each other, which surprised Tang Ze.

As far as the eye could see, Cheng Baikun was already throwing all kinds of materials into the flames again, including ore, crystals, wood, and even a dark green slime. Each material is quickly refined into a liquid by the 'three or three flow fire', and then continuously integrated into the molten steel according to the order and proportion.

On the other side, the Xuanyang meteorite had turned red, and it was poured with dark green slime, turning into a ball of molten iron in a few breaths.

In the hands of Cheng Baikun, the Ling Qi is like a living thing, constantly drawing a beautiful and mysterious trajectory in the air, changing the direction. The flames in the center of the pit swelled, and they burned even more.

The temperature around him rose wildly, and Tang Ze only felt as if his body had become a lava purgatory, the air around him became distorted, and between his breaths, it was scorching, as if his lungs were about to burn. The floor under his ass and the walls around him looked like red-hot iron plates, and if he hadn't been running his aura frantically all the time, I'm afraid he would have been roasted.

It took a full hour for Cheng Baikun to control the fire and weaken it. At the same time, he pinched the trick with his left hand, held the flag with his right hand, and then quickly divided the left and right, and the two balls of liquid above the giant pit were quickly divided into thirteen balls of fiery red liquid.

After a while, the liquid was pulled by the flames into a small, delicate throwing knife, which was molded into shape in the condensation!

This is not over, after the flying knife was formed, Cheng Baikun danced the order flag in his hand even faster, and in the space, incomparably mysterious incomparably white runes began to appear, and then connected into a line, densely wound on the flying knife. Like a sponge absorbing water, those rune threads are absorbed as soon as they touch the blade.

As the formation was engraved, the knives began to slowly cool down, revealing the color of these knives. There are twelve stalks that are pitch black with blood streaks, and the remaining one is pitch black. These thirteen flying knives all exude a sharp and pressing aura.

The formation engraving is already continuing.

Looking at these formations covering the blades of each flying knife, and counting the number of magic formations that were gradually forming on them, Tang Ze felt a trace of joy in his heart.

Another half an hour passed, and when the last rune thread was submerged into the blade, Cheng Baikun stopped waving the flag. The flying knives lit up in vain, and a transparent air flow rose from the blade, like a wave of water to impact and spread out, and just now it exuded a sharp and pressing aura, and then fell silent, as if a treasure knife had entered the sheath.

Seeing this, Cheng Baikun breathed a big sigh of relief, this set of flying knives has been refined here, and it is already more than half completed.

It was the first time he had refined twelve second-grade magic weapons and one third-grade magic weapon at one time. But in order to reflect the difficulty and complexity of refining and scare away Tang Ze's curiosity, it was a very necessary attempt. Zhang Weixian has the grace to save his life, and it is his responsibility not to let his son go astray.

So far, whether it is the refining weapon or Tang Ze's posture of resisting the heat with all his might, it has been very successful.

While secretly proud in his heart, he struck out a few magic duels in his left hand, and at the same time inserted Ling Qiwang into the side, retracting the stirring true qi into his body.

In the center of the stone room, the thirteen flying knives were still wrapped in the void by the faint flames, and they kept calcining, because the combination of the freshly refined magic weapon and the formation was not enough, so they continued to use the 'three or three flow fire' to solidify the shape and increase the stability of the qi formation.

Cheng Baikun looked at his work, nodded with satisfaction, and then turned around, no longer caring about the flying knife, and smiled at Tang Ze.

"Fourth son, the little old man wants to talk to you......"
