This sword path rough stone was so hard that it took five hours to melt completely.

Zhi Yao immediately threw the Heavenly Thunder Bamboo into it, wanting to completely fuse them together.

In the process of waiting for the fusion, Zhi Yao has been learning to carve the formation, and the book says that if you add a bonus formation to it, the power of this sword will be much stronger.

However, for Zhi Yao, a person who has no foundation in formation, it is still difficult to depict the formation well.

There is a little similarity between depicting the formation and drawing the symbols, that is, there can be no mistakes in the middle, and there can be no pauses, otherwise the previous efforts will be wasted.

And the formation is much more difficult than drawing talismans, because the simplest formation is all kinds of twists and turns, and it looks big.

Until the Sword Dao Primordial Stone and the Heavenly Thunder Bamboo had been successfully fused, Zhi Yao still couldn't draw a complete bonus formation.

There was no way, Zhi Yao could only put it down first and start forging the sword embryo.

Pouring out the liquid in the furnace and placing it in the sword mold prepared in advance, Zhi Yao took the spirit hammer next to her and began to beat the liquid in the sword mold non-stop.

This was a thorough physical work, and Zhi Yao had eaten seven tonifying pills before she could build this sword embryo.

Zhi Yao took out the sword embryo and nodded with some satisfaction. The one he chose was a relatively slender thin sword, the whole sword body was black and purple, and at the same time, some were crystal clear, and some were like purple-black crystals, shining under the refraction of light.

Next, it's time to carve out the formation.

After Zhi Yao meditated and recovered her spiritual power, she began to practice how to carve the formation again, until two hours later, she finally completed the complete portrayal of the formation for the first time.

Seeing this, Zhi Yao was overjoyed, and a sense of accomplishment arose, and she immediately buried herself in practice again.

It wasn't until the success rate reached 80 percent that Zhi Yao straightened up and put the sword embryo in front of her.

Reciting the meditation technique silently several times, until she was completely calm, Zhi Yao began to carve the formation on the sword embryo.

I saw that the black and purple spiritual power followed the lines, gradually covering the entire sword body.

It wasn't until the last stroke fell that the entire sword embryo suddenly shook violently, emitting a burst of dazzling light, and only after a few breaths did it return to calm.

Zhi Yao breathed a sigh of relief, the hardest part was finally completed.

Picking up the sword embryo, Zhi Yao violently forced out a drop of her heart's blood, fused it into the spirit sword, and then immediately threw it into the furnace again and continued to forge it.

After taking out the pill and taking it, Zhi Yao immediately sat down cross-legged to recover from her injuries, her face was pale at this time, as if she was going to faint in the next moment.

This heart's blood is her origin, and the loss of a drop is extremely damaging, and she needs to recuperate for a period of time before she can recover.

Two hours later, Zhi Yao opened her eyes and stood up.

Presumably, the spirit sword is about to take shape.

Zhi Yao came to the stove, looked inside, and saw a black and purple spirit sword glowing with cold light lying inside.

Reaching out to take it out, Zhi Yao was a little happy, this will be the natal magic weapon that accompanies her path to cultivating immortals, and it will be her partner.

"Let's call you 'Liyuan'!" Zhi Yao stroked the spirit sword with some joy, and then squeezed out a little blood, intending to recognize "Liyuan" as the master.

Although he has already had his own heart's work, this step of confessing the Lord is indispensable.

As soon as Zhi Yao dripped blood onto the Liyuan Sword, the bracelet on her hand suddenly emitted a dazzling white light, enveloping the entire Spirit Sword.

Looking at the situation in front of her, Zhi Yao was a little confused, because she found that Liyuan's sword body was gradually turning white, and even had a tendency to develop towards a transparent color.
