Using the Xuanmu needle as a tool for engraving the formation, Sheng Qingyun is confident that the engraving will be successful, and for more than a month, Sheng Qingyun has simulated engraving thousands of times.

When the formation pattern was engraved, Sheng Qingyun not only mobilized the vitality of the dantian, but also transferred the Xuanjin light from the Mud Pill Palace to assist, during this period of time in the hospital to help the soldiers one by one, Sheng Qingyun obtained a lot of Xuanjin light, and the light wheel behind the head of the god soul in the Mud Pill Palace was really manifested, although it was only a faint Xuanjin color, but it was also truly manifested......

Every pattern engraved, every stroke, every painting, no point, Sheng Qingyun is familiar with his chest, what position of the sword body is engraved with what formation, how to communicate and connect between the formations, and how to make up each step is practiced more than a thousand times.

When he really got started, Sheng Qingyun found that he still underestimated the difficulty of carving the formation pattern on this sword embryo, even if he had simulated engraving it more than a thousand times before, but when he actually engraved it on this sword embryo, Sheng Qingyun still regretted that he didn't get a few ordinary sword embryos to actually engrave a few times.

It's just that now the arrow has to be sent, and no matter what, it has to be engraved hard, and there must be no mistakes or omissions.

The method of Sheng Qingyun's engraving is to mobilize the vitality of the dantian through the Xuanmu needle and turn it into a gas blade, and the air blade falling on the engraved object is not like a blade carving, but penetrates into the body of the engraved object in a special way, forming a special vitality formation pattern and becoming a vitality channel.

Sheng Qingyun's Yuan Qi infiltration engraving, it is easy on ordinary objects, but it is very difficult to encounter this sword embryo made of extraterrestrial strange things, I don't know if it is the extraterrestrial strange thing itself is too dense, and it is extremely difficult for the vitality to penetrate and engrave, and Sheng Qingyun found that if it weren't for the fact that he not only mobilized the dantian vitality when he engraved it, but also mobilized the scarce Xuanjin light from the Mud Pill Palace to engrave it together, and hid a trace of Xuanjin light from the Xuanmu needle in the air blade, and it was precisely because of the existence of that trace of Xuanjin light that the qi blade could barely penetrate the surface of the sword embryo to engrave。

Sheng Qingyun engraved very slowly, can not be compared with the speed of a turtle or a snail, compared with the speed of Sheng Qingyun's engraving, the speed of the snail crawling is at least comparable to the speed of a maglev train.

Sheng Qingyun's carving speed is very slow, very slow, and the whole person is also unified, and the spirit and spirit are highly integrated.

Sheng Qingyun concentrated on engraving, and suddenly forgot the time, forgot himself, forgot everything around him, and there was only one thing in his eyes, heart, and soul, engraved with the flying sword formation.

Concentrated, never had concentration, the sword embryo on the formation slowly formed, a little bit spread, two days and two nights without the slightest rest of the concentration engraving, and finally the last perfect palace, at that moment, the entire sword body engraved intact array flowed, the brilliance was shining, the sword embryo trembled and jumped, Sheng Qingyun pinched and played a trick, the sword embryo Huaguang disappeared, the flowing formation pattern also stopped, and the sword embryo seemed to be asleep.

Chen Yilong, who had been staring, was shocked and excited when he saw the vision that appeared after Sheng Qingyun finished carving the formation pattern, the more magical it was, the greater the final perception gain, he was already impatient to know what the scene would be after this sword completed the final tempering, opening and sacrificing the sword, and whether it would usher in the legendary catastrophe?

Driving Sheng Qingyun out of the sword-casting room, Chen Yilong was ready to complete the final quenching and opening of the sword, and as for the final sacrificial sword, Sheng Qingyun had to complete it himself.

In order to quench this sword, Chen Yilong searched the warehouses of the Special Operations Bureau and the Wumeng, and found many things, including the cold spring water of the Tianshan Mountains, the snow that does not melt on Mount Everest, the ice that has been in the polar region for thousands of years, and the underground chalcedony milk......

Sheng Qingyun was driven out by Chen Yilong, and as soon as he returned to his residence, he fell asleep, in fact, even if Chen Yilong didn't drive him, he felt that he couldn't bear it, this was the first time since he practiced that he felt so sleepy, the chaotic one-color vitality in the dantian that had been tempered by yin and yang was actually very little, and the entire dantian seemed empty except for the yin and yang vortex in the middle, and the faint Xuanjin Wheel behind the head of the god in the Mud Pill Palace was gone, and the Xuanjin light earned these days was squandered.

A few days later, Chen Yilong sent someone to find Sheng Qingyun and asked him to put another bowl of blood to quench the sword.

Sheng Qingyun was a little depressed, how could this Chen Yilong's sword casting make people bleed at every turn? But for the sake of his flying sword, Sheng Qingyun, who had recovered, did not hesitate to release most of the bowl of blood to Chen Yilong.

After getting Sheng Qingyun's blood, Chen Yilong quickly prepared a solution for quenching, and the sword that had been burned in the sword casting furnace for several days was taken out by Chen Yilong's operating mechanical arm, and as soon as he put it into the solution, a sound like a dragon's groan sounded, and it spun and rushed to nine days.

The dragon's roar resounded through the sky, and everyone who heard it was horrified, and they didn't know what was going on, and eagerly searched around for news.

Chen Yilong's eyes were blazing, his eyes were fixed on the sword in the quenching solution, and after a while, he operated the mechanical arm to pick up the sword and turn it to a special washing and grinding machine tool, ready to open the sword.

Chen Yilong personally washed and grinded, did it extremely seriously, and several apprentices around him also watched attentively, giving the sword to open the front is also a very technical job, like Chen Yilong, a sword-casting master also has a unique opening skills, it is rare that this time Chen Yilong did it himself, and did not hide his generosity to let them watch on the sidelines, such an opportunity, how could they not cherish it, and this time they completely watched the process of casting the sword, it was an extremely valuable experience for them, and it was a valuable wealth for them to learn to cast the sword in the future, and few people in the swordsmith's life had the opportunity to cast the sword, Now the sword cast by Chen Yilong for Sheng Qingyun has shown all kinds of miracles, and after the opening, it is definitely a peerless sword, even if it is not cast by them, it is fortunate to participate in it, and seeing the peerless sword cast with his own eyes is also the most valuable experience of his life.

After three days, Chen Yilong finally opened the sword, and the flying sword dragon roared after the opening, the cold light was pressing, and the sword body formation was looming, like a dragon cruising, like a phoenix flying.

Chen Yilong looked at the eight-sided long sword behind the opening here, his eyes were full of love, just like looking at his newborn child.

Sheng Qingyun, who was notified to come to the sword casting room, looked at the flying sword held by the mechanical arm, his eyes flashed with blazing light, a few meters away, Sheng Qingyun could feel a mysterious feeling of heart and blood, this sword was like a part of his body, Sheng Qingyun was sure that this feeling came from the fusion of his own blood and sword when smelting and quenching, as well as the penetration and engraving of the golden light behind the head of the Dantian Yuan Qi and the Mud Pill Palace Divine Soul during the engraving, the feeling of being connected by blood......
