"Master, shall we go and invite a spirit master over?" Mu Chendi looked at the demon cores piled up into a hill in front of him, and his saliva was about to flow down.

Feeding the demon core to the natal spirit beast is not as simple as raising domestic animals, and if it is not controlled properly, it is likely to cause damage to the spirit beast.

If it is fed properly, the natal spirit beast can truly absorb all the power in the demon core.

And all of this needs to be controlled by the spirit master.

However, the number of spirit masters is scarce, and most of them have been invited away by major forces, such as the five spirit masters in the Emperor Academy, all of whom give priority to cultivating natal spirit beasts in the top classes.

Liu Shaobai glanced at the demon core in front of him, took one casually and looked at it, but before he could speak, he suddenly saw the two brothers of the Du family who had disappeared before, and at some point, they actually ran back to the dueling arena, and the two were followed by a majestic elder.

When the elder appeared, the eyes of the students of Class 9 lit up.

"Gu Yao? Why did they invite Gu Yao? Mu Chendi was so shocked that his jaw fell to the ground.

Although there are Imperial Spirit Masters in all the major academies, the number of Imperial Spiritual Masters is scarce, and there is not enough at all, and Gu Yao, who was invited by the two brothers of the Du family, is the number one Imperial Spiritual Master in the Lonely City.

Gu Yao was originally the chief spirit master of a big force, but this person was greedy by nature and had a great appetite, and he escaped after causing a big disaster among the forces, and then came to the lonely city, and became an idle spirit master in the lonely city, and he asked for a very high price for cultivating natal spirit beasts, and not only asked for money, but also collected a part of the demon core, which can be said to be very black-hearted.

However, Gu Yao's level of cultivating natal spirit beasts was extremely high, even if everyone knew that the price of looking for him was extremely high, there were still many people who came to the door.

After Gu Yao came to the dueling arena, he saw a pile of demon cores piled up in front of him at a glance, and his eyes narrowed slightly.

"I said how much did you spend on inviting Gu Yao here?" Mu Chen rushed to Du Hong's face and asked in a low voice.

Du Hong compared the number slightly, and Mu Chendi almost didn't bare out of his eyes.

He knew that the two living treasures of the Du family were rich, but ...... That's a staggering number, isn't it?

"It's only been half a month, and my brother and I thought that we had to do something, and we couldn't put everything on the master alone, so I gave up my blood and money to invite Gu Yao over." Du Hong felt pain a little now.

Mu Chendi silently gave Du Hong a slight thumbs up.

"Rich, capricious."

Du Qingzheng walked up to Liu Shaobai and said, "Master, this is Master Gu Yao Gu, we specially invited him to come over and cultivate the natal spirit beast for us." ”

Liu Shaobai stood up and looked at Gu Yao, who had a tall posture in front of him.

Gu Yao looked around, his brows furrowed slightly, and he looked at the two brothers of the Du family and said, "As you said before, everyone here has to cultivate their natal spirit beasts?" ”

The two brothers of the Du family nodded and said respectfully: "Yes, Master Gu, how much time do you think it will take?" ”

Gu Yao twisted his eyebrows and said coldly: "Nonsense, if you had said that there were so many people, I wouldn't have come over, this is too much time for me, there are many people looking for me to cultivate life-running spirit beasts, don't you want me to waste all my energy on you?" ”

This glance swept away, at least dozens of people, such a huge number, really made Gu Yao very unhappy.
