I was in Douluo, and Tang San stole my home at the beginning

A month later, at night, inside the house.

"There are no useless martial spirits, only useless spirit masters!" After writing the phrase on the cover of the book, Yu Xiaogang put down his pen.

"With these ten core competitiveness theories, I think it will be enough to attract Bibi Dong's attention."

"The next step is to wait for the right opportunity." Thinking this, he carefully put away the book, got up, turned off the lights and went to bed.

The next day, I went to the library to read as usual.

Zhu Wu was the same as usual until three days later, when the time agreed with Bibi Dong arrived.

They still met at the intersection, still went to the third floor together, and still sat by the window.

"I'm going to the toilet. You wait here for a while." Sensing Yu Xiaogang's gaze heading this way, Zhu Wu stood up with a calm expression.

"Okay." Bibi Dong smiled and watched Zhu Wu walk away. Then she turned around, spread out the small notebook on the table, and started thinking.

Seeing this, Yu Xiaogang on the other side knew that this was a rare opportunity. His heartbeat inexplicably accelerated. He took a deep breath, stood up and walked closer.

However, he did not walk directly towards Bibi Dong, but walked towards the bookshelf at the back, with a calm and indifferent expression, as if he was here to get a book.

When the footsteps approached, Bibi Dong noticed it and subconsciously looked up, then her eyes flashed.

"You finally can't bear it anymore?"

I feel a chill in my heart.

"Brother Yingtian left on an excuse. I guess he realized that Yu Xiaogang was about to make a move, right?"

"That's good. Let's solve it as soon as possible, so that this piece of shit won't be here every day and it's an eyesore. Humph, he wants to rely on the spirit master theory he learned from my Spirit Hall Academy to convince me, and then use me to cheat the Spirit Hall of knowledge. Don't you know your own weight?"

"Today, I, Bibi Dong, will let you understand what it means to be ashamed!"

Thinking of this, he lowered his head to turn to a new page in his small notebook, picked up a pen to write down a few questions, and then lowered his head pretending to be in deep thought.

"Are you also studying the classification of martial spirits?" Soon, Yu Xiaogang's voice came from behind him.

Bibi Dong turned her head and looked at Yu Xiaogang, who was standing not far behind her with three books in his hands. She smiled and nodded.

"Yes! Classmate Yu Xiaogang, are you also doing research?"

Yu Xiaogang's heartbeat quickened again, his ears felt slightly hot, but his expression remained calm. He nodded gently, "I have done some research."

Bibi Dong pretended to be amused and asked, "Yu Xiaogang, how do you think we should classify them?"

As he spoke, he pointed to a seat not far away and said, "How about sitting down and discussing this?"

"Okay." Yu Xiaogang nodded slightly, walked slowly to the seat Bibi Dong pointed to and sat down.

Humph, he's pretending to be so serious. Bibi Dong snorted in her heart, but her expression was serious. She looked at Yu Xiaogang quietly and waited for what would happen next.

Yu Xiaogang knew that the other party was testing him, so he spoke calmly.

"Generally, we should follow the common opinion of the spirit master community at present and distinguish between weapon spirits and beast spirits, and then make distinctions in details?"

"For example, plant spirits?" Bibi Dong gave an example directly.

"Plant martial spirits cannot attach themselves to a body to fight like beast martial spirits, but they can be separated from the body like weapon martial spirits for use by the spirit master. Therefore, they can be classified as weapon martial spirits." Yu Xiaogang said lightly.

"But plants should be considered a kind of life, right?" Bibi Dong pretended to be silent. "Tools, in real life, generally refer to man-made tools such as swords, guns, sticks, rakes, needles and threads, including ritual objects made of gold, silver and gems, which are dead objects."

"Plants, however, exist in the form of natural life in reality. It would be inappropriate to classify them as objects."

"But the martial soul is not a real life after all." Yu Xiaogang said calmly.

"But when we add spirit rings to martial spirits, we need to follow the laws of reality, right?" Bibi Dong said with a smile, "That's why the spirit master world has never heard of anyone adding animal spirit rings to plant martial spirits."

“I think that’s the biggest reason.”

“What our predecessors said may not be entirely correct. Plant martial spirits may not be unable to have animal spirit rings attached to them.” Yu Xiaogang’s expression remained calm.

"For example, blue silver grass?" Bibi Dong asked.

"Blue Silver Grass is inherently weak, but it is also very tolerant, which means it will not reject most animal spirit rings." Yu Xiaogang said calmly, "You can consider absorbing the spirit rings of some snake spirit beasts, such as the Mandragora Snake."

"The body of the Mandragora Snake is tough and difficult to be injured by ordinary swords and knives. It also carries a powerful neurotoxin. Absorbing this kind of spirit ring can not only improve the toughness and hardness of the Blue Silver Grass, but also inherit some of the neurotoxin, adding a certain degree of aggressiveness to the Blue Silver Grass."

"For example, some poisonous spiders produce silk that is one of the most resilient things in the world. If the blue silver grass can inherit this property, the vines that extend from it will definitely become extremely resilient."

"So, classmate Yu Xiaogang hasn't put his theory into practice yet?" Bibi Dong asked.

"It has never been put into practice." Yu Xiaogang's face remained calm, "But it is feasible in theory."

"Theory is just theory after all, and it still needs to be tested in practice. Otherwise, once it spreads and causes spirit masters to imitate it, it will bring about bad consequences and mislead young people." Bibi Dong said lightly.

"As far as I know, although plant martial spirits can inherit the characteristics of animal spirit beasts, due to their own plant characteristics, they are not very compatible with the spirit ring energy of animal spirit beasts."

"As a result, the inherited properties will be greatly reduced, including the toxicity."

"After all, animal poisons are completely different from plant poisons."

So, the Spirit Hall had already put this theory into practice? Yu Xiaogang felt his neck getting hot.

"Classmate Yu Xiaogang." Bibi Dong's voice suddenly rose again.

"Just now you said that plants can be classified as weapon spirits, then what if the spirit is a part of the human body?" Bibi Dong said.

"This..." Yu Xiaogang was stunned for a moment as he had never heard of it before. He then took a deep breath and forced himself to stay calm.

"Aren't humans also a kind of animals?" he sighed.

"But we humans call ourselves humans, isn't it to distinguish ourselves from animals? This is also a manifestation of our human wisdom!" Bibi Dong shook her head repeatedly, "So, if we confuse humans with animals, it would be a bit inappropriate."

"For example, livestock are also a kind of beast, but they are food for humans. How can we classify ourselves as food?"

"And if they are really classified as one, doesn't that mean that humans can eat other humans at will? How is this different from animals?"

That’s right, Yu Xiaogang, you are a beast. To achieve your goal, you even deceived girls!

"." Yu Xiaogang's face flushed slightly, and for a moment he didn't know how to answer.

"I think it would be safest to reclassify it and call it the body spirit." Bibi Dong pretended to be thoughtful and said, "It means a part of the human body."

Yu Xiaogang took a deep breath to calm himself down, and nodded slightly, "That does make sense."

"What about the food spirit?" Bibi Dong asked again.

"Yu Xiaogang, what do you think the food spirit should be transformed into?"
