Feixu licked her dry lips, "Once when you and Yue Xiuzhu were fighting, your war beast swallowed her war beast, my war beast just now fought against Gao Guan's war beast, but it killed the other. The Lingyu in the source of spiritual power has been swallowed, is there any particularity here?"

After listening to Fei Xu's question, Ning Xi expected it.

Sure enough, she was a friend of hers. She looked at things and asked questions sharply and carefully.

"All the war beasts I have refined can be upgraded, but I have to constantly devour the spiritual jade and materials as nourishment. After reaching a level that can be upgraded, the war beasts will report back to the master, and then come to me to reform and refine. If you control it, you can advance." Ning Xi said with a smile.

The super mecha that she studied can be continuously upgraded by swallowing fusion materials, so it is also applied to the war beast.

"What?" Many people exclaimed, "Can the beast be upgraded?"

Fei Xu's eyes widened in disbelief, but thinking of Ning Xi's temperament and behavior, he couldn't help but believe it.

"What do you mean, my beautiful maid and war beast can be upgraded to Xuanpin or even Earthpin in the future?" He asked with some unsteady breathing.

Ning Xi nodded and smiled, "That's true!"

"However, it's not that easy to upgrade. The key point is to see the amount and level of spiritual jade and materials swallowed by the war beast." She added a sentence after changing the conversation.

Feixu was stunned and continued to ask, "Then why did it only swallow the Lingyu and not other materials?"

Ning Xi's last battle beast devoured Yue Xiuzhu's battle beast.

"The war beast will automatically identify the materials that are useful to it. The war beast that Gaoguan just now belongs to the inferior grade of the high-level war beasts of the yellow rank. Therefore, except for Lingyu, your war beast is useless to swallow those materials." Ningxi added many elements and characteristics of future mechas when he built and refined the war beast.

For example, the mecha automatically recognizes and devours fusion materials and other functions.

The main reason is that this world does not have an intelligent light-brain, so he can only use his spiritual sense and spiritual power to control the beasts. Otherwise, Ning Xi will be able to better utilize the beasts' advantages as mechas.

But one day Ningxi will replace the intelligent optical brain with a substitute. Although the technological civilization of this world is not as developed as the future family, it also has a lot of knowledge and smarter creations that the future world does not have.

Fei Xu swallowed his saliva, his eyes filled with a kind of shining light, "Amazing, it turns out that war beasts can still play like this, I have gained a lot of knowledge today!"

The others also recovered from their shock, looking at Ning Xi like a monster.

This little prince's war beast talent is unparalleled, and they don't know what words to use to describe it.

"However, in the battle, I suggest that if it is not the enemy, it is better not to devour the materials and spiritual jade of the opponent's war beast. After you completely refine and fuse the war beast, you can control whether to swallow it or not."

Ningxi paused and said, "I refined this kind of upgradeable war beast, and I don't want its master to kill other war beasts indiscriminately. In fact, if you want to upgrade, you only need to provide enough spiritual jade and corresponding or higher level. It is more realistic for the materials to be swallowed and merged by the war beasts."

"By treating the war beast as a friend, you can increase the degree of fit between the human and the war beast, and it will always pay off."

Ning Xi used to be madly in love with mechas, so he had feelings for every mecha or war beast he made, and he would also respect the mechas and war beasts made by others.

"Of course, with the exception of enemies, unpleasant people, and war beasts." Ning Xi added, that's how self-willed!
