Ning Xi knew that the thinking of the emperor and the others was fixed, so he would feel that it was impossible.

"What I said is true."

The old prince dodged and landed in the open space in the center, "The old man will know if you try it!" ”

He had long seen that the spiritual power source refined by Ning Xi was different from the ordinary, and the energy was much stronger, but he really didn't expect that the lasting time would also increase by thirty percent.

Whether it's true or not, try it and you'll find out!

Immediately, he took out two identical yellow-grade high-grade war beasts, and war beasts of this level consumed more spiritual power sources.

Then the old prince put the spiritual power source that the royal family prepared for Ning Xi but didn't use on the table into one war beast, and put the spiritual power source refined by Ning Xi into another war beast, and then controlled the two war beasts to fight.

Everyone's eyes fell on the two war beasts and stared, and after more than an hour, the spiritual power source of one of the war beasts was in a hurry.

After another cup of tea, the war beast's spiritual power source was completely consumed and paralyzed, and everyone found that it was the one that put the royal family to prepare the spiritual power source.

The old prince stepped forward to change the new source of spiritual power for the war beasts, and controlled the two war beasts to continue fighting.

After half an hour, the power source of the other war beast spirit began to be in a hurry, and it was gradually depleted.

The look of shock in the old prince's eyes had already dissipated, and he laughed out loud, "The spiritual power source refined by the stinky boy is really close to forty percent more than the ordinary one. ”

He took out the spiritual power source that Ning Xi had refined again, opened the box and observed it carefully, and after a while, he asked Ning Xi, "The materials you used to refine have changed?" ”

"Well, I found that after changing the two materials, the power contained in the spirit jade can be brought into full play." Ning Xi nodded.

The old prince's eyes were full of relief, and he reached out and patted Ning Xi's shoulder heavily, "Stinky boy is doing a good job!" ”

Ning Xi was flattered, "It turns out that you can also praise people, old prince!" ”

The old prince glanced at Ning Xi, "Stinky boy!" ”

"Old prince, you have exhausted the spiritual power source I have refined, what are I using for my war beasts!"

Ning Xi pitifully came to the old prince's side, "You know, I'm poor!" ”

The old prince glared at Ning Xi angrily, "Come to the Ministry of Industry tomorrow to find the old man, and the old man will compensate you for two materials and two pieces of red spirit jade." ”

"I knew that the old prince was the best!" Ning Xi slapped a sycophant.

The old prince put away the source of spiritual power refined by Ningxi, and the smile in his eyes did not decrease, "The old man is too lazy to pay attention to you!" ”

Then he turned around and quickly left the Royal Colosseum, as if he was in a hurry to go back and study something.

After the old prince left, the people present came back to their senses from disbelief, and many people looked at Ning Xi with great complexity.

They didn't expect that this gentleman would not only refine the source of spiritual power, but also transform it to increase its energy and longevity.

Such a thing, but even Ning Xi's father, Ning Yanchen, the first war beast master of the Yin Kingdom, did not do it.

The eldest prince and the third prince and their faction were shocked, but their hearts were not so happy.

"Haha, Xi'er is worthy of being Yanchen's son, such a war beast talent is better than blue, I am very relieved!" Jing Ruofeng's heart was shaken, but he was sincerely happy.

"Thank you for the emperor's compliment, I will definitely refine more powerful war beasts and spiritual power sources for the emperor in the future." Ning Xi also liked and respected the emperor.

Ning Xi is absolutely protective of the people he approves, and he also regulates the people he hates.

Jing Ruofeng's war beast is at the ground level, and Ning Xi wants to refine it far away, but he is very happy, and it is not in vain that he loves this child so much, and this intention makes him very useful.

"Okay, I'll wait for that day!"
