Who made him a sword-wielding Gu Immortal?

Looking at the three Gu flying backwards, Tie Yunqing's mouth corners, which had been pulled up, slowly flattened at this moment, leaving some concave points facing each other. The smile on his face slowly disappeared.

"Is this the legendary, open champagne at halftime?" Tie Yunqing's eyes were blank.

At this moment, a ball of dark golden powder fell from the air.

It was the proud remains of the Iron Back Gu.

He got off the bed and silently took back the three slightly injured Gu worms.

Tie Yunqing exhaled a foul breath. He attributed his failure to the final disappointment of Gu refining and the disrespect for the great cause of refining Gu worms.

"Come again!"

With the experience of the first failure, the second Gu refining was much smoother.

The light red iron true essence rose again, holding the two slightly damaged Sword Edge Gu and the last Iron Back Gu in the air.

Tie Yunqing skillfully manipulated the Gu worms to merge their wills, and endured for another hour.

In an instant, the Iron Back Gu and the Sword Edge Gu suddenly burst into dazzling white light. The two balls of white light then quickly merged together, turning into a white ball of light the size of a washbasin, with countless light spots floating and swaying irregularly.

Under the control of consciousness, the silver-white mantis quickly vibrated its wings and flew, and the second sword-edge Gu also flew into the white light.

The sword-edge Gu that flew into the light ball began to shake violently. After the initial tremor, the light ball stabilized.

Tie Yunqing began to control the evil thoughts Gu and flew directly into the white light ball. As it flew closer and closer, its body gradually shrank, and finally flew directly into the white light.

There was still no violent shaking, and everything was moving in a good direction.

However, at this moment, something strange happened.

The white light ball that was originally stable in the air suddenly appeared with a faint purple light, and the brightness of the purple light gradually increased.

In the end, the light ball stabilized, but the originally pure white light ball turned into light purple at this moment.

Tie Yunqing stared with his eyes wide open. He had never heard of a light purple light ball appearing when refining Gu worms, and his master had never mentioned it either.

At this moment, Tie Yunqing was in a dilemma.

Should he stop refining the Gu this time, so that the Gu worms in the light ball still have a chance to survive, or should he continue to put in Yuanshi to complete the refining.

A blessing is not a disaster, but a disaster cannot be avoided!

Tie Yunqing chose to bite the bullet and continue to refine the Gu worms. Giving up is certainly an option, but if he gave up this time, would he give up again if an unexpected situation occurred next time? What about the next time!

He threw Yuanshi from the bag into the lavender light ball one by one, and the Yuanshi turned into pure natural true essence as fuel for refining the Gu.

Yuanshi powder kept falling from the air, and a thick layer of it had already been laid on the bed.

Tie Yunqing didn't dare to count the number of Yuanshi he put in this time. As long as it wasn't over, he kept taking Yuanshi out of the bag and throwing it into the light ball.

Tie Yunqing, who had already forgotten how many Yuanshi he had thrown, looked at the light ball in the air, and the light emitted began to become softer.

His hand instinctively reached for the bag full of Yuanshi.

Disappointed, he touched nothing!

He looked down at the empty bag of Yuanshi, and then at the lilac soft light ball in the air which was still shrinking.

Tie Yunqing broke out in a cold sweat.

He had thought of countless possibilities of failure, but he never thought that the reason for his failure in refining the Gu was the insufficient number of Yuanshi.

Even if the five Yuanshi used to restore the true essence were deducted, there were still 215 Yuanshi left.

Yuanshi!

Yuanshi!

At this moment, how could he find Yuanshi immediately and continue to refine the Gu!

His body began to tremble slightly. Why was his journey of refining the Gu so difficult... Tie Yunqing vented silently in his heart.

Dong.

A slight muffled sound attracted his attention.

Tie Yunqing looked down and saw that half of the Yuanshi fell out of his open shirt because of the trembling.

Looking at the half of the Yuanshi, which was still stained with some fine dust, Tie Yunqing recognized it at a glance. This was the half of the Yuanshi that the master threw out from the crack of the door today, in the name of funding him to refine the Gu.

Without thinking, Tie Yunqing grabbed half of the Yuanshi and threw it into the lavender light ball with great precision. At this moment, his heart beat violently and his breathing was rapid.

Under Tie Yunqing's gaze, the light ball actually slowly shrank and finally disappeared completely in the air.

The evil thoughts Gu, two sword-edge Gu, and one iron-back Gu were all gone. A brand-new Gu insect quietly floated in front of Tie Yunqing.

Its appearance was still a fat mantis, but it should have been golden on its back, but now the mantis's back was a strange purple.

This is - the second-level sword-spine Gu!

Until this moment, Tie Yunqing breathed deeply and happily. His heart was not dead, but was put back into his stomach.

Flying with wings, the fat mantis transformed by the sword-spine Gu flew around Tie Yunqing twice with great effort, and then landed in his palm.

Is this Gu normal? Tie Yunqing looked at the Gu insect in his palm and thought silently in his heart.

Sword-spine Gu.

As the true essence in Tie Yunqing's orifices was infused into the Gu worm, four purple illusory long swords suddenly appeared in the air.

The long swords were broad and thick, about half a meter wide, distributed in the four directions of the human body, protecting the owner.

I finally have a defensive Gu, which makes up for one of my shortcomings. Tie Yunqing showed a look of joy.

This time, the refining of Gu was full of twists and turns, which made Tie Yunqing suffer a lot, and his own assets were almost exhausted. The result was that he combined and refined a second-level defense Gu.

Tie Yunqing didn't care how dirty and messy the bed was at the moment, and he just lay on his back with his legs spread out, forming a Tai character.

Then he closed his eyes to relieve the soreness in his eyes caused by refining Gu.

He silently calculated in his mind that in order to refine this first second-level Gu worm in his life, the resources he spent before and after included:

One second-level evil thought Gu cost 650 Yuanshi.

Two sword-edge Gu, because this Gu was not circulated, Tie Yunqing estimated that it was about 450 yuan each, and two totaled 900 Yuanshi.

Two iron back Gu totaled 410 yuan.

The total cost of refining was 220.5 Yuanshi.

Therefore, the total cost of refining the second-level Gu this time was about 2180.5 Yuanshi.

It was about three to four times the cost of buying a second-level Gu worm.

Refining Gu is difficult. Tie Yunqing, who tried it for the first time, now has a very deep and concrete understanding.

Through this Gu refining, he has a deeper understanding of Jianfeng Gu.

Jianfeng Gu is the beginning of a series of Gu worms that Tiejian formed into Gu sword killing moves. All subsequent Gu worms are refined from Jianfeng Gu as a basis to form new Gu worms.

Jianfeng represents attack, while the second-turn Jianji Gu represents defense. By analogy, the Gu worms refined under Jianji Gu should no longer be attack or defense Gu, but a moderate type of Gu worm.

The third Gu is likely to have one of the three functions of movement, storage, and reconnaissance. Tie Yunqing kept making guesses in his mind.

The most critical part of gathering Gu into a sword killing move is the first-turn Jianfeng Gu. As for how Jianfeng Gu was obtained, Tiejian was unwilling to reveal any information, and Tie Yunqing still doubted the statement that Jianfeng Gu was reversely refined from the second-turn Gu.

The first-turn Jianfeng Gu has the same status as the Moonlight Gu in Guyue Village. The method of refining Moonlight Gu is definitely more important and secret than refining the second-level Moon Mark Gu and Blood Moon Gu.

At dawn, Tie Yunqing, who had been up all night, was just about to take a nap on the bed.

Dong Dong Dong!

A knock on the door came into the house.

Tie Yunqing looked helpless. He didn't need to ask. It must be his master who came to urge him to go to the family to receive the family task of the second-level Gu Master.

Tie Jian, who usually sets up a stall, is the elder of the family, but why is he so concerned about the family task? Tie Yunqing really can't figure it out.
