Yuna Stone.
'If my guess is correct then when I absorb Qi it will be converted to Qi points.'
Jin in his life on Earth had read countless system novels and wrote many fanfictions.
So he had a rough idea of how the system works by looking at its interface.
To confirm his theory, he summoned the martial spirit that his predecessor awakened, the Purity White Lotus.
A white lotus surrounded by one gray halo magically appeared in front of Jin.
He urged it to absorb Qi.
It was like how one urge the lungs to absorb air.
Nothing happened immediately but Jin was patient.
After 2 minutes of continuous absorption.
[Qi points+1]
He was ecstatic, his guess was correct. Now to confirm his second theory.
He continued to absorb Qi for 20 more minutes and earned 10 Qi points.
He added all of it to his Purity White Lotus's experience bar.
[Martial Spirit: Purity White Lotus(Gray Class 1 Halo) <10/10>]
The row began to glow and the 1 gray halo surrounding the martial spirit started to split and became two haloes.
Looking at his interface.
[Martial Spirit: Purity White Lotus(Gray Class 2 Halo) <0/20>]
'It worked.'
Jin had an urge to laugh like a mad man.
"What shit Shao clan, you all destained my Purity Lotus, this young lord will show all of you that this lotus can't be underestimated."
Now that he had confirmed his theory.
He opened the shop interface again.
[Corpse Devouring Fire: Very low Qi absorption rate, low attack power, medium affinity to fire. Special: Burns corpses at a very fast rate and absorbed Qi stored inside the corpse.]
Using the last of his points he bought it.
Now he had two martial spirits.
His interface also changed.
[Martial Spirit 1: Purity White Lotus(Gray Class 2 Halo) <0/20>]
[Martial Spirit 2: Corpse Devouring Fire(Gray Class 1 Halo) <0/10>]
Curious he looked up the info of his Purity White Lotus.
[Pure White Lotus: Low Qi absorption rate, no attack power, affinity to wood. Special: Purifies Qi at a very fast rate.]
Looking at the sky, although they were covered with could he could tell that the sun was about to set. The had already stopped. But it was impossible to start a fire as all the nearby wood was wet.
Sighing Jin climbed up the tree that his predecessor used to kill himself.
After reaching a good height to protect himself from wild animals, he took out a water bag from his space ring and drunk two mouths full.
[Qi point +30]
[Qi point +30]
"What's this?"
This water was given to him by the elders of Shao clan. It was the most ordinary spring water that the members of the Shao clan members use to quench their thirst. But due to the high concentration of Qi in the Hell domain, some Qi was dissolved into the natural water.
Jin sighed, kids of the Shao clan sure are lucky, even the water they drink is so nourishing.
Suppressing the urge to drink more of this water, he placed the water bag back in and took out one of the Yuna stone.
Yuna stone was very common cultivation resource in the Over Heaven hell and Hell domain. But in a mortal domain, they are very rare. Only the top sects of the mortal domain have a steady flow of Yuna Stones.
If Jin sold one of these stone then he could live the rest of his life carefree.
Jin summoned both of his Martial Spirits and began absorbing the energy stored in the Yuna stone.
[Qi point+20]

He received notifications every second. After 20 minutes he started to get dizzy. He immediately dispelled both his martial spirits.
Absorbing Qi be it from the atmosphere of from a cultivation resource will use up mental energy. Mental energy naturally recovers as we rest. This meant that no one can continuously cultivate forever unless the rate of mental energy recovery matches the mental energy usage.
Jin looked at the system interface.
[Qi point: 24,000]
A major windfall.
Looking at the Yuna stone in his hand, he noticed that it had become dimer now.
Jin predicted that he had only absorbed half of the energy in it. He calculated in his mind and concluded that he had at least 960,000 Qi points worth of Yuna stones.
He wondered what would be the most efficient way to use all these points.
Should he continue to improve his cultivation, buy some weapons and armor or improve the grade of his martial spirit.
After thinking for a while, Jin decided to improve his cultivation. He was in the middle of god know where with many unknown dangers, so he needs to improve his strength as much as he can.
