"Jade Phosphor Serpent?" 

Both Gyuutarou and Ume asked together. This was the first time they hear this kind of snake.

Ye Xinghan tried to search any other information in the page, but to no avail. The book only explained the characteristic of the soul form, but didn't goes into detail.

Ye Xinghan closed the book and said to Gyuutarou, "No information further about this soul form inside the book, but I have a few impression of it. Just, I don't know if the soul form you has are the same as the thing I know."

"Anyway, the Jade Phosphor Serpent is a venomous snake. Venomous is an understatement. Because if you managed to evolve it into Jade Phosphor Serpent Emperor, you could easily destroy a country with the venom alone."

"That powerful?" Gyuutarou and Ume gasped in amazement.

"I conclude that cultivating techniques related to poison is the most suited for you. And if we even managed to get a good demon spirit with poison attribute, then your future will be limitless."

Gyuutarou went silent when he heard these words. And then he bowed deeply to Ye Xinghan, "Thank you."

"I have my own purpose to help you. If you want to thank me, then work harder to get stronger." Ye Xinghan replied.

Gyuutarou only slightly nodded while trying to hold back his tears.

Ye Xinghan thought, 'In the Demon Slayer anime, both of them had tragic ending. Even if they were villains, I couldn't help but shed tears when watching them.

Since I have the power to help them, I will gladly do it.

Maybe because they aren't supposed to exist in this world, I feel closer towards them. Hahaha..'

'Gyuutarou has incredible proficiency in closed range combat when using sickle. Hell, he even managed to kill a grown up samurai in the original anime despite being a child and never received any proper guidance. Adding the fact that he has incredible speed and poison attribute, its like he is destined to walk in the path of assassin.

"Don't be too happy, a demon beast with poison attribute is especially rare within this St. Ancestral Mountain Range. Even if we managed to find one, it would be a hard fight that is absolutely impossible without sacrifices or casualities." Ye Xinghan poured cold water on Gyuutarou head.

St. Ancestral Mountain Range that were surrounded the Glory City were filled mostly with snow wind demon beasts, that was also one of the reason Snow Wind Family became the strongest family within the city. Because the demon spirit supply for snow wind attributes were endless.

"Does that mean that I can't become a demon spiritualist???" Gyuutarou lamented.

"Rest assured, on the west of St Ancestral Mountain Range, lies a forest called Toxic Forest. It is a heaven for poison attribute demon beasts. But with your current strength, of course you just send yourself to death if you go there." Ye Xinghan said, then he added "Beside with my training regime, you wouldn't necessarily need a demon spirit within this divine continent." (Toxic Forest is canon from the original novel)

Hearing those sentences, the low-spirited Gyuutarou became excited again. He was really curious about the training that being mentioned. As long as it could make him stronger, then he would gladly do it.

"When you reach gold ranked fighter. We will go there together to search a demon crystal that is suitable for you. But if you impatient to become a demon spiritualist, I'll gladly buy a silver ranked Horned Sheep demon crytstal for you, hahahahah..." Ye Xinghan laughed loudly at his own joke. 

Gyuutarou just twitched his mouth as he silently watch Ye Xinghan rolling on the floor while laughing.

He would prefer to stay in bronze ranked forever rather than became a clown demon spiritualist. (Nie Li for example, everyone think his Panda is trash)

"Hahaa,,, hufff.. okayy that's enough. Lets continue. Ume, please hold this crystal and focus pouring your energy into it." Ye Xinghan slowly stood up and gave Ume the last soul crystal.

"Um..! Oni chan, i'll start." Ume cutely nodded while smiling. 

Then, she closed her eyes as she channeling her energy towards the crystal.

Ye Xinghan and Gyuutarou went silent and focused on the crystal.

Before long, the crystal shining and made both of them dumbfounded.

"AZURE!!"
