Levi was sitting in his room again, he had thought a lot and took a look at the bathtub full of deconstructed purified blood from the monsters he killed along with a pile of transparent monster cores surrounding them. He did not count the monsters he and Caleb killed but he roughly knew there were about 700-800 of them.
This much blood from these Elementary Grade monster was more than enough for 20-30 people to advance to Tier 1 Advance Grade from Tier 1 Elementary Grade. But Levi knew that his manual of energy accumulation was not normal. That is why he killed monsters in a frenzy to gather the required amount of materials to get to the stage of Tier 1 Advance Grade in a single session rather than to regularly cultivate and accumulate origin energy. This way his potential enemies would find it much harder to gauge his strength.
He always liked to keep things hidden as much as possible, but encountering hidden enemies from suspicious origins was what bothered him the most, along with the fact that he could not sense old man Sven Stone who had been following him and Caleb made him lose his appetite. If he had been able to use his Intermediate Grade strength along with the 5 seeds continuously, Sven Stone would not be able to bypass his senses.
That is why this was the most opportune moment for him to increase his strength as well as expose himself to the world that he has reached Tier 1 Intermediate Grade. Though this would cause a shock to everyone he was ready to face the trouble that came with the attention once he upgraded his strength to Tier 1 Advance Grade using the vast amount of blood and cores of monsters he had gathered.
He then looked at the 20 buckets filled with blackish essence liquid. Those are the natural affinities those monsters he killed possessed and he had deconstructed those affinities from their corpses. Currently, he was pondering whether to finish the essence liquid first or absorb the energy pool he had gathered in the bathtub.
"Well, I guess it doesn't matter. but let's finish the strength upgrade and then absorb the affinities. Absorbing essence liquid after increasing my strength would increase its effectiveness.... probably." Levi said before getting naked and jumping into the bathtub.
He started absorbing energy in a frenzy, the room became a bit misty due to this much energy revolving around the room, even the air took a turn and started revolving around Levi gaining momentum.

Shatter!!
The windows of Levi's room shattered making a loud sound in the night.
"Holy hell, what do people do these days in their room?" a passerby spoke narrowly avoiding the pieces of shattered glass.
"Isn't that Levi's room? what is he doing attracting this much commotion?" One of the men who lived in the area spoke, while he was walking with his friends.
"Probably something big, don't you know he is an Anderson, they got more money and resources. Maybe it is one of those rich-kid types of toys behind this commotion or maybe some miraculous medicine."
The people only paid minor attention to this incident before going about their business.

"Hooh! Hooh! Alright 6 seeds. One more and I will cross the minor threshold and advance to the Tier-1 Advance Grade." Levi was sweating but his overall condition was good, he could feel his power rising steadily at a rapid pace.
He knew that the energy required to cross a minor stage was way more difficult than creating a seed by absorbing energy. Although he had waited for 5 days before doing this, he had planned it. His slowly increasing bone density was the reason that gave him confidence.
After reaching Intermediate Grade Tier 1 his bone density was improving rapidly before slowing down day by day. He knew that his bones were powerful enough to handle the influx of energy that came while advancing. Once he reaches the Tier 1 Advance Grade he does not have to be afraid of creating more seeds.
"No time to waste. Let's do THISS!!" Levi roared, which annoyed the people who lived in the same apartment building as Levi. This time the commotion was more than what the room itself could handle pieces of plaster from the walls got scraped right off, dust and clothes and whatnot flew rapidly in the tornado whose center was Levi himself.
He kept absorbing and groaning at the bouts of pain he received due to the large amount of energy that was entering him through his pores.
"Come on!! Just a little bit more!!.." Levi held on, while the blood and cores of monsters were also trying their best to support Levi with more quantity.
"AAHHHH!" suddenly Levi felt a sharp pain.
Levi could feel his bone cracking from the inside, barely able to handle this much of energy. But he knew there was not much of choice once he began the advancement process. Just when half of the resources were consumed, he could feel a gentle energy descend upon the cracks formed in the skeletal trying to mend them slowly. he could feel a seventh seed form somewhere in his skeletal and embed itself at that point.
CRACKK!!
All over his skeleton small cracks were forming and repairing with the vast amount of energy filled in them. The cracks had impurities oozing out of them at a rapid pace, and also slowly increased the strength of his bones. After breaking through he did not immediately start forming the 8th seed but instead let his bones get baptized by the energy before going forward.
5, 10, 15, 30, 60 minutes passed.
Levi did not stop to look at his body condition but he felt that his bones were so strong that forming the 8th and 9th seeds should be child's play for him. His bone strength was so strong that even Tier 2 people will think twice before clashing their fists with Levi. Levi might get his skin and flesh blown into pieces but not his bones. Relying on his bone strength alone he could kill Tier 1 Advance Grade like taking a walk in the park.
SWIRL! SWIRL!
The energy tornado that was silent for a while now took its time again to get into the speed, Levi was sure this time that there would be no problem with him forming the remaining seeds, but the energy requirements had increased proportionally to his strength.
1 hour passed.
It took 1 more hour to absorb the remaining blood that had been left but it had successfully built the 8th and 9th seeds.
"Finally the peak of Tier 1 has been reached now I can continue with my plan to advance to the next Tier-- Ohh Shit!! what's going on!!??" Levi grabbed his stomach before going straight to his bathroom.
Levi knew that impurities would be released, but he just did not know how it would be released from his body? He got his answers after the bathroom break.
A Tier 1 person's body is not much different than a normal human without talent. Such kind of mortal body has many impurities. Levi's sudden increase in strength from Intermediate Grade to Peak Tier 1 was like a cleansing of such a mortal body from top to bottom. The basic impurities were removed very easily, this alone would cause him to have more vitality than others. The purification of bones is also the purification of bone marrow which in turn is responsible for the purity of blood which concerns the next Tier, Tier 2. This was also beneficial to his advancement to Tier 2.
Levi looked dead tired after the intense bathroom break, he looked around his house and saw his own mess but ignored it. He still smelled bad so he took a shower and then proceeded with the buckets of essence liquid, nothing was more important than strength. He had more than enough money to get a new house more splendid than this one and that was exactly what he was going to do after he was done with his upgrade session.
Levi was already spent and hungry, the buckets of essence liquid looked like delicious food to him that he could gobble down.
"Turns out it was the right decision to increase my Tier first before drinking the essence liquid."
Levi drank the buckets full of liquid at a rapid pace, the black liquid that went into him was like sweet honey that got digested like a vacuum cleaner cleaning dust. He just binged the whole 20 buckets before giving a loud burp. But his mind was already occupied with the large amount of information from the essence he digested, alongwith the increase of strength from the Dark Elemental affinity upgrade.
"Ohh I feel full now more than ever before. Hmm.. if I drink the essence liquid of other monsters like the dark claw bear I can understand their skills and execute them if my body can physically that is. This is truly a miraculous treasure." Levi said before looking through the skills of the monsters he had killed and absorbed.
The moon was still above his head and he did not plan on sleeping, especially after the huge upgrades he received. He was excited about his new skills and wanted to go through them all at once before finally going to sleep.
