The next day, as soon as Ning Xi arrived at the Ministry of Works, he was called to the inner room by the old prince.

Yan Xiao and Ye Jun were already sitting in the room, and the three of them greeted each other.

"Now that the old man is refining the source of spiritual power, you are carefully watching." The old prince picked up the materials on the table and began to refine.

There are not many materials to refine, but the parts formed by the materials are very small and complex, and they may be wasted if you are not careful.

Finally, a red stone exuding spiritual energy was inlaid into the refined oval wooden box, "This is the most critical material for the spiritual power source, the spiritual jade, and the exhaustion of the spiritual jade also represents the exhaustion of the spiritual power source." ”

As soon as the red spirit jade was placed in the box, a layer of red light flashed.

The old prince said to Ning Xi: "The strength of the red light flickering also represents the strength and duration of the spiritual power source. ”

Ning Xi found that refining spiritual power sources and making mecha power boxes also had a lot in common, so he thought about it and asked, "Old prince, are spiritual power sources still divided into different levels?" ”

"Of course, the spiritual power source is also divided into red, yellow, blue, green, green, green, orange, and purple according to the quality of the spirit jade. The old prince replied.

Ning Xi pondered for a moment and then asked, "Is there only one source of red power?" ”

"Of course, there is only one source of red power refined by a ground-level war beast master." The old prince said as a matter of course.

"Isn't there a way to enhance the spiritual power drive for a longer period of time?" Ning Xi had researched the results of expanding the power of the mecha power box to make it much longer, so he felt that the spiritual power source should also be able to be improved.

The old prince glanced at Ning Xi inexplicably, "No way, the source of spiritual power relies on spiritual jade to operate, and the power contained in spiritual jade is fixed." ”

Ning Xi found that the old prince and the others were limited by their stubborn thinking, but in fact, they couldn't change the spirit jade, but they could start from other materials!

However, she didn't bring it up, and she was going to study it herself.

"Do you understand how to refine the source of spiritual power?" The old prince asked.

"Understood." Ning Xi smiled and nodded: "I'll almost be able to refine it." ”

The old prince raised his eyebrows, "The spiritual power source is the most critical core of refining war beasts, and all the materials must be refined into parts that are finely connected with the spirit jade in order to operate normally, and the requirements for soul power are very high, and ordinary war beast masters are not competent, which is also a reason why the refining power of spiritual power sources is very low." ”

"The spiritual power source can generally only be refined by a high-level war beast master of Huang Pin, and it is easy to fail, do you really know it?" The old prince emphasized.

"It's really good!"

After Ning Xi watched the old prince's refining, the whole process had already been reflected in her mind, borrowing the principle of making a mecha power box, she felt that she had been able to refine the spiritual power source alone.

The old prince was skeptical, thought for a while and said to Yan Xiao: "You go and prepare a material for refining the source of spiritual power, let her try it." ”

"Ahh Yan Xiao was shocked, obviously he didn't expect the old prince to give such an order, the materials for refining the power source were very expensive and scarce, and couldn't help but ask: "What if the refining is broken?" ”

You must know that even he, a high-level war beast master of the yellow grade, still struggles to refine the spiritual power source, refining ten can only succeed in most cases and only two in most cases, and only four in the best time.
