After a while,
At the edge of the West City, Eero's figure flickered and landed on the ground; the Ki layer on his body disappeared. He walked inside the city.
Appeared in the marketplace, looking through his video phone, the list of companies and outlets offering the items he is looking for.
"This Hovocore outlet is best for winding wires and coils also other hardware tools. Also, I should buy metallurgy engineering tools and anti-gravity engines from Capsule Corps. Hardware materials and assembling tools can be bought from Zemo." Looking through the list, murmuring, Eero walked through the outlets one by one and ordered all the items after paying. He will receive them later.
Finally, he appeared in front of Capsule Corp. He is going to use Gohan's name, although it's a little shameless, but he is not here to harm anyone, just buying something important which he can't get normally.
Looking at Vegeta standing at the entrance with six years old Trunks, Eero became speechless. 'What the hell? I haven't even entered, yet I encountered this bodyguard.'
Vegeta's flinched his brow furrowed feeling a gaze, turned around glanced at Eero walking toward the headquarters residence.
"Hello, does Miss Bulma live here?" Eero appeared beside them and politely asked, looking at Vegeta and Trunks, especially Vegeta, similar to the anime, looks like a proper villain type, exuding a stingy aura.
"What do you want?" Vegeta asked with a frown, looking at Eero's thoughtful expression and handsome face.
"I am here to buy something important for my invention which I can't get from the market easily. Also, Gohan recommended me the Capsule Corp; he said I should meet his aunt Bulma," Eero replied calmly.
Vegeta and Trunks were surprised looking at Eero. "You know Gohan?"
"I am his friend." Eero nodded and replied.
"My mother is gone somewhere; wait for a while she will return soon," Trunks spoke, Vegeta gave a hmph, turned and left like a tsundere.
Eero was speechless. 'This guy is really a masterpiece. Also, even he can't sense my Ki, it seems my black Ki has a special ability to conceal Ki.' He thought to himself, then waited for a while inside the waiting room.
After a while,
"Hello, I am Bulma. What do you need for your invention?" Bulma appeared with Trunks, curiously looking at Eero.
Eero glanced at Bulma, similar in the anime, blue hair, mature figure, and easy-going personality. Also, her brain works very well, beauty with brains huh, but her choice is very bad. Who will love someone like Vegeta?
"Hello, I am Eero, Gohan's friend. I need those items for my invention." Eero passed the tech items list.
Bulma nodded with a smile, glanced at the list on the paper, more she scanned more she was surprised, more solemn her expression became, glanced at Eero curiously asked, "Are you inventing the Gravity Chamber?"
Eero nodded, replied calmly, "Yes, I have already manufactured an 8-fold one. In order to increase the effects, I need these technologies."
"Amazing, you are a little genius. Can I ask you why are you manufacturing a Gravity machine? I can't think of any big use of such high gravity," Bulma asked again suspiciously.
"It's for physical training purposes," Eero replied.
"What, but that is not applicable for the human body. Are you making it for yourself?" Bulma was surprised then asked doubtfully.
Eero nodded with a calm expression.
Looking at Eero nodding calmly, Bulma expression became strange then hesitated a little, after a while nodded, "Wait for a while I will arrange these items then you can take them away."
Eero nodded with a smile then replied, "Please give me an account number. I will send the payment."
Bulma wanted to reject payment, but Eero insisted then she had to accept it. Eero was looking at her thoughtfully, 'She also had created a gravity machine for Vegeta in this arc I think; I should ask her about some theories and precautions.'
Eero then asked about gravity increase proportions and other related queries and precautions.
Bulma was extremely surprised by Eero's inference and ideas about gravity machines.
After a while, Eero left Capsule Corp, thoughtfully, 'It seems my idea about gravity was right. 2-fold earth gravity can reduce physical strength by half, 50%; 4-fold can reduce it to 25%; 8-fold gravity can reduce it to 12.5%, 16-fold gravity to 6.25%, 32-fold gravity to 3.125%, and 64-fold gravity to 1.5625%. Finally, at 128-fold gravity, it can reduce below 1%.'
"I will try to create a 128-fold chamber first, which will be enough for me for a long time, and I can easily save myself in front of Majin Boo," Eero muttered thoughtfully.
After buying famous dishes and ingredients products from West City, he flew back toward his home thoughtfully.
...
A few days passed,
Gohan was busy as a golden warrior, and Videl also participated in a lot of heroic activities.
Eero, on the other hand, didn't care. He just brought the ordered items from West City and started his research and gravity chamber manufacturing process.
It took him a few days outside and a few months inside the domain to create a gravity chamber. Also, to his surprise, a merge option appeared after his creation.
He clicked it, and instantly a basement layer appeared attached below his portable home. This area is huge, 1000 square feet, similarly his house which also became larger, upgraded to a four-room house with two portions and a basement. The second portion became a pet area and lab area, rest area with an artificial grass lawn, recliner, and an indoor small swimming pool.
"It seems my portable home can upgrade after each merging," Eero muttered thoughtfully, looking at four rooms, including a guest room and a huge lounge area. "It became a proper portable villa instead of a portable home."
Eero appeared in the basement, looking at white and blue coloring and square-shaped tile design on the whole basement walls and floors.
Eero patted the walls, feeling non-metal material but extremely hard. He was confused, "What kind of material is this?"
Then shook his head, glanced at the small touch display just beside the door. Eero clicked it.
Instantly, different Gravity options appeared on the screen. Eero clicked the Gravity increase arrow to 2 fold.
