Although Sebastian had a lot of pills, the effects weren't good by consuming them directly. He could refine pills, but Lazarus claimed the pills he refined as trash.
Different grades of pills could be made out of the same ingredients, and the ones Sebastian produced were considered midrange.
Under Lazarus' guidance, Sebastian's pill refinement skills took a great leap as well, and he could produce third-grade pills.
Lazarus managed to obtain a huge amount of spiritual herbs and also a spiritual artifact in the form of an alchemy pot. All these things were left behind by the people who entered the forbidden ground of the demon lord in the past thousands of years.
Many of Lazarus' subordinates were also trapped within the forbidden ground, but they were on the outside. These tribesmen were faithful and would give him any good things they had.
Despite that, some of the people in the Demon Tribe had recently turned disloyal. For instance, the two demonic girls who captured Sebastian—one of them was faithful to Lazarus, while the other wanted to have all of Sebastian's essence blood for herself.
The herbs left behind by the people were of high quality, and Lazarus was a grandmaster at pill refinement. He passed down many formulas to Sebastian and guided him in refining fourth-grade pills.
Just like that, another decade passed. Sebastian's pill refinement skills improved so remarkably that he could independently produce fourth-grade pills. With the help of Lazarus' demonic power, he successfully refined a pot of fifth-grade pills.
His cultivation made another breakthrough within these ten years, and he became a seven-star demigod. He wasn't far from eight-star and could set up a fourth-level formation by himself.
"Can I leave now, Your Majesty?" Sebastian's eyes were looking hopeful.
It had been 20 years since he stepped into Mayhem Tower. Previously, he was 28 years old. The time he spent here was more than half of his life, but this was because time flowed ten times faster within the tower.
This wasn't the only magical point about the tower. Although 20 years had passed inside, there were barely any changes to Sebastian's appearance.
The Mayhem Tower had sped up time, but Sebastian's bodily functions were aging according to the flow of time in the outside world.
Still, his experience was real—ten years of learning formations and another ten years of learning pill refinement. Day after day, year after year, his learning process was dry and boring. He had no entertainment and didn't know how he pulled through.
Weapons, also known as artifacts, were usually divided into two categories—regular weapons and destined weapons.
Anyone could use a regular weapon while only one person could use a destined weapon. The latter was useless to someone who had snatched it away, unless the owner of the destined weapon severed the ties they had with the destined weapon.
Also, it was more complicated to forge a destined weapon, and the requirements of the ingredients were very high.
The benefit after successfully forging a destined weapon was an increase in strength. On the other hand, a regular weapon didn't have such an effect.
In the beginning, Lazarus only taught Sebastian the way to make regular artifacts, starting from the most basic lower weapons.
Time flew past, and another decade passed by.
