There was two hours left before Redsoul's lesson, so Xiao Yan decided to make some alchemy.
He took some of the ingredients Duan Jian bought for him and started to refine them.
——————————
The finished product was a bottle of Heavenly Note Dew.
It's use were the same as Spiritual Stones for cultivation but it was easier to absorb.
He duplicated it with the Philosopher's Ring and he had to use 300 Spiritual Stones for it.
The ingredients were bought for 100 Spiritual Stones, so it "only" saved him time for 200 stones.
Calling Duan Jian, he asked him consume one and to cultivate in front on him.
He already knew that it was more expensive than using the stones, but he wanted to know just how much time it could save him.
Duan Jian rapidly broke through to become a 2-Fate.
After ten minutes, he became a 3-Fate while he finished absorbing the remaining effects of the dew.
{It would have taken him 150 Spiritual Stones to obtain the same effect in a span of nearly two weeks}
{But it's that fast only because of the compiled cultivation technique, it would normally take much more time}
{…}
{I'll wait to sell the demon spirits to Li Xingyun first, then I'll start to receive a steady supply of Spiritual Stones}
{I don't want to use the power of the TDSB just to accelerate the formation of the Deity Lakes, I'll wait having Gu Bei's demon spirits first}
——————————
When Xiao Yan's group went to their class, most of their classmates were gossiping about them.
Their battle in the Ghastly Ruins was one of the hottest topics for the students since two days!
Gu Bei came and happily patted Xiao Yan's back, "Everybody is talking about how you guys humiliated Gu Heng's underlings in the Ghastly Ruins! Haha, he must be burning with rage"
They talked a little and he gave him a storage ring with hundred thousands of demon spirits, "I easily sold your demon spirits and bought what you needed. But now it will take much more time to sell ordinary bloodline ones"
"I don't have anymore of ordinary bloodline, but I'll have ancient bloodline ones in three days"
He simpl nodded and then went to talk with Gu Yan.
——————————
Xiao Yan started refining the demon spirits inside of his painting-artifact while still listening to Redsoul's lesson.
Today, he talked about the differences between each bloodline and each growth rate of demon spirits.
Some of the students turned to Xiao Yan and sighed with envy.
The rumors already said that Xiao Yan integrated with a powerful Dragon Bloodline God Level Growth Rate Demon Spirit.
Normally, only the successors of the strongest families could integrate with such a demon spirit!
——————————
While returning home, Xiao Yan contacted Hua Ling.
By concentrating on his soul seal, he could talk to him and even see what he was seeing, the distance being limited by the cultivation of the two.
He asked him the locations of the almost dried up Deity Lakes he knew of and told his fiancees that he would be back in a few hours.
Xiao Yan used the Thief God's Ring to activate his void-form, then took the appearance of Murong Yu and went to the nearest of the Deity Lakes by teleporting again and again.
This one was guarded by eight Heavenly Fate Cultivators.
He negotiated with them to peacefully buy the lake for eight Dragon Bloodline Demon Spirit of Excellent Growth Rate and they readily accepted.
Since they weren't bullies, he didn't plan to take advantage of them.
The reason why he chose Murong Yu was because he was known as a genius at the peak of 9-Fate Heavenly Fate.
He could rob them the lake, that's why they listened to what he had to say and didn't attack him.
Even if it took him only 800 Spiritual Stones to duplicate these demon spirits, for them the value was 8 000 Spiritual Stones.
Their Deity Lake would need four years to produce that!
Not to mention that they would also need to protect the lake from being taken by other forces during that time.
It was a very good deal for both sides!
After taking the Deity Root and putting it in his painting, Xiao Yan repeated the same thing with the remaining thirty-four almost dried up Deity Lakes.
Each time he proposed the same amount of demon spirits as the number of people guarding the lake, and everyone happily accepted.
When he finished, he nearly didn't have any Spiritual Stones left, but he knew he would soon have hundreds of thousand.
——————————
Back home with his own appearance, Xiao Yan and his fiancees went inside of the Myriad Miles Rivers and Mountains Painting, and then he used the power of the TDSB on it.
He started to teach them about alchemy while using the Nightmare Demon Pot to finish refining the demon spirits received from Gu Bei.
It would be a waste to use the TDSB to just speed up the formation of the Deity Lakes!
The books he compiled with the LoHP went straight to the essential, dramatically decreasing the time he needed to teach.
A few months later, they could refine all of the pills sold by the Alchemist Association of Glory City.
By that time, the Deity Roots already formed their Deity Lakes.
Altogether, they were giving him 150 000 Spiritual Stones and 150 Spiritual Stone Essences each month.
Xiao Yan then duplicated a Spiritual Stone Essence and it took him 400 Spiritual Stones.
Since the market price was 1 for 1000, he could make profits just by converting stones and exchanging them.
He also duplicated the ingredients bought by Duan Jian and continued his teaching until they could make Heavenly Note Dews a few weeks later.
Only then did they leave the painting artifact.
Concerning the demon spirits, he managed to refine around five hundred Dragon Bloodline Excellent Growth Rate.
He decided to keep the originals and to continue on refining new ones to have more varieties.
