"Thank you, Master!" Su Yu kowtowed again.
"Su Yu swears by the heavens and earth that I will never betray Master in this life!
I will serve Master for the rest of my life!
If I have second thoughts, I will be punished by the heavens and earth! "
"Rumble!"
When Su Yu made the vow, the heavens and earth shook. Two undetectable rays of light fell from the sky.
Luo Qingtong had a realization in her heart.
Su Yu's words had been recorded by the heavens and earth!
If she violated it in the future, she would be punished by the heavens and earth!
This kind of punishment was much harsher than offering one's soul and serving Luo Qingtong as master.
Because she offered her soul to serve Luo Qingtong as her master, if Su Yu had second thoughts, as long as Luo Qingtong was willing to let her go, she could still live!
However, the heavens and earth were the arbiters of the heavens and earth!
As long as Su Yu had any thoughts of disrespecting or even harming Luo Qingtong, the heavens and earth would sense it and punish her immediately!
Moreover, after she was killed, she would never be reincarnated!
Luo Qingtong's heart was shaken.
She didn't expect Su Yu to make such a heavy vow.
She saved Su Yu only because her authority was shaken, so she used the Cheng family as a warning to others.
Su Yu had sold her life to her!
"Good!
Su Yu, since you vowed to follow me forever, I won't treat you unfairly. "Luo Qingtong narrowed her eyes and raised her hand to summon Snowball.
"Take it with you and let it grow with you!
The Southern Wilderness is dangerous, but it can protect you at critical moments!
In addition, this is the weapon used by Elder Liu. It's a good spiritual weapon. Combined with the King Level Technique, Raging Flame Cut, its power can't be underestimated! "
"Later, I'll copy the King Level Cultivation Method, Raging Flame Slash, and give it to you!"
Luo Qingtong's voice was light, but she didn't know how shocked Su Yu was.
King Level Cultivation Technique?
Raging Flame Slash?
Copy it out for her?
This … Not only did Master learn the Raging Flame Slash, a King Level Cultivation Technique, on the spot, but he also completely understood it and could copy it into a secret manual for her?!
'Is Mistress … really not a Martial Emperor?!'
This … this was not something a Martial Master could do!
Su Yu was shocked beyond words.
She didn't even pay attention to what Luo Qingtong said about Snowball. She only thought that it was just an ordinary spiritual pet.
"Mas … Master?!"
He watched as Luo Qingtong copied the King Level Cultivation Method right in front of him and concocted a bunch of medicinal liquid for him on the spot.
Su Yu realized that he was almost numb from the shock!
Oh my god!
How much ability does Master have that hasn't been revealed yet?!
Master's refining speed was simply faster than any other alchemist she had seen before!
Su Yu had never seen any alchemist refining medicine like Master. He just casually glanced at it, then raised his hand and rubbed it. A bunch of medicinal liquid came out!
Moreover, the medicinal strength of each medicinal liquid was very rich!
Even if Su Yu didn't study the elixirs, she could see that the elixirs refined by her master were extraordinary!
The medicinal strength was so rich that it was even richer than the best medicinal liquid she had encountered in the Su Family!
"Master … You … What level of alchemist are you?" She couldn't help but ask.
