This problem is not a problem at all for Li Zhenbang, who has an acquired bag, and when he sleeps, he can just throw it into the acquired bag. Now there are Duoduo and a water fairy in the bag the day after tomorrow!

Thinking of the water elves, Li Zhenbang suddenly had a flash of inspiration in his mind, if the water elves could also evolve in this way, it would be good. The water elves are not the magical beasts of this world, and the specific level upper limit is not clear to them, if they can really evolve by devouring, then they can be upgraded infinitely!

"Teacher, can that elemental demonic beast evolve by devouring the corpse and demon core of the same lineage?" asked Li Zhenbang expectantly.

"Elemental beasts, it's not okay to devour corpses, but it's okay to devour demon cores. Delileika thought for a moment and said.

When Li Zhenbang heard this, he excitedly hugged Delilaika and kissed him fiercely on the face.

"Teacher, this news of yours is so meaningful to me!"

Delilaika made Li Zhenbang stunned, this is too sudden!

"Teacher, did you carry some earth-based demon cores? I don't believe you only gave me one egg to hatch. Li Zhenbang looked at Delilaika expectantly.

"Uh...... You little rabbit, you can't save me a little coffin money!" Delilaika screamed in pain, but still took out a small bag of earth-based demon cores and handed it to Li Zhenbang.

He had already prepared, although the level was not high, but most of them were third-order, and there were a few fourth-order, although these demon cores could not allow the little iron-armored giant rhinoceros to evolve to maturity, but it was not a big problem to raise to the level of fourth-order demonic beasts.

Under normal circumstances, devouring the demon core provides more energy than devouring the corpse of the demonic beast, the demon core is the essence of the demonic beast, and the corpse is just a part of the energy stored in the life of the demonic beast.

After taking over the earth demon core, Li Zhenbang looked at Delilaika with some twist and said, "Teacher, I know that you are the best for me, so do you still have a water demon core?"

"What? Water Demon Core? You little rabbit cub, you are a Chinese cabbage when you are a Demon Core! How much do you want? No, no!" Delilaika glared at Li Zhenbang and said angrily.

"Oh!" Li Zhenbang lowered his head and looked aggrieved.

Delilaika's heart twitched when she saw it, and she sighed helplessly, and said, "Wronged!

Obviously, Delilaika didn't deliberately prepare the water demon core, so she took it out one by one and didn't put it in a bag. Li Zhenbang took over the demon core, a total of five, one fourth-order and four third-order.

"Thank you, teacher, you are the best! When I return to the imperial capital, I will definitely bring you the best gift! It is even better than the gift to Teacher Yang!" Li Zhenbang said with a smile.

Originally, Delilaika was still a little unwilling, but when she heard that her gift would be better than Yang Bing's, she was in a good mood, patted Li Zhenbang's shoulder, and said with a smile: "Little rabbit cub, you have to talk and count, if I find that my gift is not as good as Yang Bing's, hum!

"Teacher, don't worry, your gift will definitely be better than Teacher Yang! I promise! You are so good to me, how can I not take it to heart!" Li Zhenbang said obediently.

"That's pretty much it, it's not in vain that I love you!" said Delileika, pulling her beard happily.

"Teacher, if there's nothing to do, I'll go back first, it's not too early!

"Well, go back, remember not to walk out of the academy at will, or it will be dangerous! I won't be able to take care of you when I go back, but I will always keep an eye on you!" said Delileka with concern.

"Teacher, don't worry! I will definitely take care of myself! Then the disciple will take his leave!" Li Zhenbang bowed, took a few steps back, turned around and left.

The little iron-armored giant rhinoceros chased after Li Zhenbang's buttocks, although it had just hatched, but as a fifth-order demonic beast, his control over his body was still very good.

Delilaika looked at Li Zhenbang's distant back, sighed, and said to himself: "Little rabbit cub, you must not get into trouble again! During this time, you must take it with you in the academy, don't run around! I try to think of a way! Poison Sect ...... Alas!"

Li Zhenbang left Delilaika's sight, ran to a corner where no one was paying attention, and fed the little ironclad giant rhino a third-order demon core.

The little iron-armored giant rhino took the demon core and swallowed it directly, looking at Li Zhenbang with a look of unfinished eyes, but Li Zhenbang didn't dare to feed too much at one time, in case the energy was too great, it would be bad if it exceeded the bearing capacity of the little iron-armored giant rhino.

Not long after eating the demon core, the eyelids of the little iron-armored giant rhino had already begun to fight, obviously the energy of the demon core began to take effect, and soon the little iron-armored giant rhino closed his eyes and fell asleep.

Li Zhenbang put the little iron-armored giant rhinoceros into the acquired bag, released the water spirit, and after feeding a third-order demon core, he put it into the acquired bag.

Li Zhenbang put the remaining magic cores and the magic cores in the space ring in one bag each, and handed the two bags to the elf mouse Duoduo.

Tell Duoduo to help him take care of the little iron-armored giant rhino and water elf, if they are completely absorbed, continue to help feed themselves, and if there is anything abnormal, notify yourself in time.

Although you can also explore the situation in the bag at any time, it is not as convenient and fast as the one who lives in it.

A week has passed, and the little iron-armored giant rhino has grown a few times compared to the beginning, and has already eaten a total of three third-order earth attribute demon cores.

To Li Zhenbang's surprise, the water elf is much faster to absorb than the little iron-armored giant rhino, a third-order water attribute magic core, the water elf can be completely absorbed in half a day, not only does not need to sleep, but after eating the demon core, he will become very excited.

In a week's time, the water spirit absorbed ten third-order water-attribute magic cores and three fourth-order water-attribute magic cores. Li Zhenbang was distressed and relieved at the same time, because after absorbing the fourth-order water attribute magic core of the third lesson, the water spirit had successfully advanced from a fourth-order demonic beast to a fifth-order demonic beast.

In the past week, Li Zhenbang has not been out of the gate of the academy again, and naturally there is no danger. Those twelve puppets had already returned to the Poison Sect, and their daily cultivation would transmit a large amount of energy to Li Zhenbang, and the daily energy still had a slight tendency to increase, obviously the cultivation speed of the twelve people had increased a lot.

The news they transmitted to Li Zhenbang about the Poison Sect made Li Zhenbang breathe a sigh of relief. There have been some problems within the Poison Sect recently, so there is no time to take care of Li Zhenbang in a short period of time.
