Gan Xinglei thought carefully, organized his language, and replied, "Since the contract, there has been a constant though somewhat indistinct feedback enhancement, and my strength has definitely improved a bit compared to the morning. However, as for the speed and effect, without a comparison, it's hard for me to say for sure, but definitely not as much as you."
Su Han's strength was clearly evident to him, although he had never asked about the specifics of the Angel Envoy's Claw.
In his mind, though, it was a given that it was a skill naturally acquired, and its considerable strength was categorized under the strength enhancement of the Angel Envoy and receiving more power feedback.
However, only Su Han himself knew what was truly happening with him, with most of his strength stemming from Fusion and natural enhancement, making it somewhat difficult to estimate.
After thinking for a moment, he changed his question to, "How many days would it take to reach First-level Intermediate?"
Gan Xinglei thought seriously and said, "Based on my feeling, if nothing unexpected happens, it should take about seven days."
After the contract, there was a vague sense of the Angel Envoy's strength, which was a link between them, and naturally, they could feel the advancement of this power.
However, whether the speed of strength enhancement was consistent every day was something he could not guarantee.
Su Han looked at Yan Meiyu, who, after a bit of thought, said, "It should take me about five days. When I control the Rot Skin Rat, the gradual increase in speed is not slow; I can feel my constitution slowly improving and my speed picking up a little."
From morning till afternoon, there had hardly been any rest; previously, when working in sales and running around all the time, she would have been utterly exhausted by now, but today she wasn't.
Comparing the two cases, if he put aside the aspect of Fusion, Su Han's Angel Envoy's advancement speed was likely close to Yan Meiyu's.
'Looking at it this way, perhaps there isn't much difference between everyone, the key to accelerating strength enhancement still lies in Fusion materials.'
Having set his mind, he looked at the two and said, "Let's rest for now. Tomorrow, we'll call Zhu Xiong and continue clearing the place."
Gan Xinglei and Yan Meiyu didn't stay at Su Han's place, though they had rooms, it wasn't appropriate.
Once the two left, the room became empty and silent, save for the light of the electric lamp and Su Han himself.
The lamp was part of the supplies found today; connected to a power bank and set to the lowest brightness, it could last a long time.
"Fusion with LV2 ordinary metals already takes three to four hundred pounds of metal, and LV3 will likely require even more, possibly over a thousand pounds. Without leaving this building, it will be hard to gather enough in the short term. We need to switch to a different type of material."
In terms of suitable materials for Fusion, he had previously considered this, eventually choosing metal. Now, if not using metal, the first choice would still be the previous few materials: stone, water, wood, and so on.
Su Han took out those items and placed them in front of him, thinking, "Let's first test the material suitability."
Material suitability determined the speed and efficiency of Fusion, which was very important at this stage, as it related to the speed of his own strength enhancement.
[Material detecting ordinary rock: proceed with Fusion?]
"Fusion"
As Su Han tested them one by one, when the Angel Envoy's flesh enveloped a rock and slowly began to Fuse it, his brow furrowed slightly.
"This speed, it's a bit slower than metal."
His hunch was right, and when the Fusion was complete, the Fusion Degree appeared: ordinary rock: 0.03%.
A stone slightly smaller than a fist had earned just this little Fusion Degree; to complete LV1 Fusion, he'd need at least a few hundred pounds or more, a quantity he couldn't manage, and time wouldn't allow for it either.
Interrupting the Fusion, the Fusion Degree of the ordinary rock disappeared, and Su Han picked up the next Fusion material.
A cup of water, Fusion time 3 minutes, Fusion Degree 0.05%, slightly higher than the rock but still slower than metal, requiring a large quantity; his reserved water might not suffice, creating a resource scarcity.
A piece of wood, Fusion time 3 minutes, Fusion Degree 0.08%, higher than the previous two, but still not as good as metal, and the problem was similar: finding wood in the apartment wouldn't be much more substantial than finding metal.
For a moment, Su Han felt frustrated; time could be made available, but the building's limited resources were the more challenging problem to solve.
If only he were in a garage or at a rebar yard, he could satisfy the ordinary metal Fusion to the greatest extent possible.
"The most common items in the apartment now, which should also be available... wait, the corpses of the Four-armed Corpses."
Suddenly, Su Han thought of the corpses, weren't the corpses and monsters the most plentiful things in the building right now?
Moreover, considering compatibility, things of the same origin should at least not be worse than metal, as for what attributes would be added, he'd know after trying.
Su Han stood up, holding a flashlight in one hand and a crowbar in the other, and ordered the Angel Envoy corpse to open the door.
There was a corpse from yesterday's kill in the seventh-floor corridor—ready-made experimental material.
Arriving at the corridor, the smell of blood mixed with a faint stench, he covered his nose slightly and muttered, "Even if the Fusion isn't great, this body should be cleaned up; otherwise, it will rot and breed disease."
Drawing near to the corpse on the ground, Su Han commanded the Angel Envoy to step forward, grabbing onto the corpse's body, while he began concentrating mentally.
[Detected Fusion material: corpse flesh and blood, proceed with Fusion?]
'As expected, it can be Fused.'
"Fusion"
No sooner had Su Han given the command than he saw countless tendrils of flesh on the Angel Envoy, worming towards the corpse, intertwining and Fusing. The corpse body was disappearing at an extremely fast rate.
In less than 5 minutes, only a twisted skeleton remained on the ground. The skull deformed, the spine contorted, bearing no resemblance to a human.
Feeling a power feedback more pronounced than after the previous three Fusions, Su Han was delighted. He opened the Angel Envoy's attribute panel and saw that it was a success.
Angel Envoy: Corpse
Rank: First-level Intermediate
Skills: [Claw] [Iron Skin]
Fusion: LV2 ordinary metal, corpse flesh and blood 18%
Just one corpse had achieved a 18% Fusion Degree. How could Su Han not be thrilled? This meant that even if the percentage needed increased later on, he wouldn't need more than seven or eight corpses to complete the first Fusion.
And in these two days, the number of corpses he had cleared and killed on the fifth, sixth, and seventh floors clearly exceeded this number. Tonight, if he followed the trail from the daytime, Fusing along the way, he could complete the first Fusion.
With no time to lose, Su Han took his flashlight and began entering rooms on the seventh floor with corpse bodies, passing through one after another, continually Fusing the corpses.
From the seventh floor to the sixth and down to the fifth, after the Fusion of the tenth corpse's flesh and blood, Su Han had achieved tonight's KPI.
[LV1 corpse flesh and blood Fusion, the corpse has achieved an Advancement in form: Four-armed Corpse]
As the prompt sounded, Su Han looked astounded. When he looked towards the Angel Envoy corpse, he immediately saw beneath the glowing red body, muscles bulging, and bones cracking with a ka-ka sound, stretching incessantly.
The already two-meter-tall Angel Envoy surged in size again, becoming a two and a half meter tall behemoth, with a thick waist and broad back, muscles bulging like a bull. Between its spine and shoulder blades, its muscles swelled, the bones twisted and deformed, and in no time, like bamboo shoots sprouting from the earth, two brawny arms burst forth.
The muscles in the arms swelled with a sense of power, and the claws were sharp, not different from the original limbs.
Angel Envoy: Four-armed Corpse
Rank: First-level Intermediate
Skills: [Claw] [Iron Skin]
Fusion: LV2 ordinary metal, LV1 corpse flesh and blood 2%
The rank remained unchanged, but Su Han could feel that the Four-armed Corpse was two to three times stronger than before, yet the breakthrough was not far off.
A strong sense of warmth also reflected back to him, providing immense comfort to his limbs and joints, as muscles and bones were immersed and constantly improved, making his own strength even greater.
"The effects are better than expected, and the compatibility is high. Although it's not a skill, the changes in form are likely even more valuable. It seems that for a while, the goal needs to change, prioritizing corpse Fusion," Su Han said with a smile, having found suitable materials for Fusion—a very good thing indeed.
