19- Verdant Great Sun Physique

Beside the academy was a Gu room. The Gu room was not big; it was only 100 meters² in size.

In a Gu Master's road to cultivation, a Gu is the key to strength.

At the end of class, the excited teenagers rushed towards the Gu room.

"Form a line, enter two by one," some voices suddenly yelled; it was natural that there were guards outside the Gu room. The youths went in two at a time and came out. Finally it was Liu Yang and Liu Yin's turn to enter the Gu room.

This room was a mysterious room. The four walls all had holes; in each one of these embedded square holes were another square hole. Each of the holes differed in size, some big and some small. The bigger ones were no bigger than a an earthenware cooking pot, the smaller holes no smaller than a fist.

In the many square holes were all kinds of containers – there were grey stone basins, verdant jade dishes, exquisite grass cages, earthen stoves etc. These containers kept in all kinds of variety of Gu.

Some Gu were silent, while some Gu made a lot of noises, creating chirping, clucking, rustling sounds and so on. All these noises combined together to create a sort of life symphony.

"All the Gu worms in this room are Rank one Gu." Liu Yin glanced around, immediately aware of this.

"It is because we are rank one Gu masters. The clan will definitely not place a rank two Gu worm here." Liu Yang started explaining to his sister.

Generally speaking, Rank one Gu Masters can only use Rank one Gu. If they used higher level Gu, these masters would need to pay an extremely heavy price. In addition, Gu need to be fed. The high cost of feeding higher level Gu was often not something lower ranked Gu Masters could afford. Thus to Gu Masters who were newcomers, they would always pick a Rank one Gu worm as their first refined Gu unless under a special situation.

There is great significance to the first Gu that a Gu Master refines – It will become their vital Gu, interconnecting their lives together. If it dies, the Gu master will suffer a huge blow.

"You have Verdant Great Sun Physique, but there are no space path Gu worms in the clan." Liu Yang sighed as he walked straight along the wall on his left.

"Currently, you have to choose the local Gu of the Liu clan. I will later refine the Gu for you when the convoy arrives here in a month."

Liu Yin couldn't help but sigh, their clan used to specialize in the Qi path and now specializes in the wind path. Nor were there any space path Gu worms in the clan.

One of the top layers of the holes in this wall had a row of silver plates. In every plate was a Gu.

These Gu were crystalline and shaped like a ball; it was like a piece of red quartz.

Known as the Qi-blade Gu, this variety of Gu was the local Gu of the Liu clan and many of the clansmen would choose the Qi-blade Gu as their vital Gu.

Since it was all Rank one Qi-blade Gu, there was very little difference among one another. Liu Yin casually chose one and took it. The Qi-blade Gu was very light, comparable to the weight of a piece of paper. The insect occupied a small area of her palm; it was roughly the size of a common jade pendant. As Liu Yin put it on her hand, she could see through it and gaze at the lines on her palm.

On the other side was a Gu worm that looked like a cicada but had no legs.

Known as the whirlwind Gu, this variety of Gu was the now local Gu of the Liu clan and many of the now clansmen would choose the whirlwind Gu as their vital Gu.

The use of this Gu worm spread within the clan after they came to Feng Jing Mountain, which had a lot of wind path resources.

"Well since you picked a Gu worm, let's go." Liu Yin nodded when she heard her brother.

With one last look and finding nothing wrong with it, Liu Yin put the Qi-blade Gu into her pocket and walked out of the Gu room. Outside the Gu room, the queue was still quite long. As soon as the next person in line saw Liu Yin and Liu Yang leave, he went into the room hurriedly with excitement.

"Big brother, you did not choose a Gu worm."

"I took whirlwind Gu." Liu Yang took this Gu while Liu Yin was busy listening to him.

"But it won't be my vital Gu. I have already chosen my vital Gu, but I have to refine it first. I am waiting for the caravan that brings materials to refine my Gu worm."

Liu Yang had been planning his vital Gu for two years and had been gathering materials to refine it two years ago.

The Gu worm he wanted to refine was a rank five Gu worm. This Gu worm does not have a lower rank.

He had failed to refine that Gu twenty-one times in a row and had modified the recipe more than once to increase the success rate, the last batch of materials to refine that Gu in the caravan should come a month later to Liu Village.

Normally his success rate in refining a rank five Gu worm was 90%, but the materials required to refine this Gu worm were rather special, and it was difficult to combine them due to conflicting dao marks.

Even when he refined 'family Gu' to rank five for Liu Liu, he succeeded on the second try.

"Let's go home." He was planning to refine Primeval Essence Gu as vital Gu for himself and his sister and then later replace it with a proper Gu worm for them after the convoy came.

It was easy for him to replace his vital Gu with another, as he had made a suitable formation to facilitate doing so without side effects.

He originally designed the formation for Liu Liu in order to replace her vital Gu with another one. He succeeded and family Gu became her vital Gu.

Currently Liu Yang had four Rank Five Primeval Essence Gu, Liu Liu, Liu Yin and Liu Yang each had one, the latter of which was used in Liu Liu's cultivation formation.

Liu Yang had trained his sister well using primeval essence Gu, so his sister had a lot of experience using Gu worms. And not only that, she also had a complete set of Rank five Gu worms and she knew their use very well.

Liu Yang put a lot of effort into training his sister, so she has the battle strength of a rank five Gu Master.
