With the night vision system interface displayed on his screen, WuYan could see everything clearly in the deepest and dark cave. The demonized Goblin Lord is finally dead with its back fall against the floor, the top of its head was blasted open by a sheer destructive force, the lifeless staring eyes from its face are looking at the ceiling. Part of its brains was splattered onto the ceiling due to the blast and one by one, they are falling back onto their owner's face, smearing it face.
"Would you mind telling me what you just put into its mouth?" Ada questioned WuYan about the item that exploded.
"The thing that exploded in its mouth is called 'Fire Lance'. Originated around 10th-century China, the first generation in firearms history with a crude and simple design. A spear that was attached with an iron gourd bottle that's filled with black powder and hard iron shrapnels. Then when ignited the rope from the bottom of the bottle and the flames had contacted the black powder, it would create an explosive effect within the condensed bottle and blast out all the shrapnels in high pressure, obliterating things at high speed, giving extra range of attack." WuYan explained his knowledge.
"Fire Lance. Sounded like one of the weapons used against the Gods and heroes." Ada said.
"I am curious. They are Gods so what type of weaponry that your creator used to fight them?" WuYan asked out of curiosity.
"Long range, medium range, close range, melee...all sorts of it but those blueprints schematics are locked inside the brain storage of my body. With that short amount of time left before the power supply ran out, I could only transfer info about the Gods and heroes into this body."
Ada said.
"Is there any method to transfer all those blueprints in the future?" He asked.
"Yes but only if we found a massive energy supply that could start and run the facility again." She said,
"Alright. We will figure out the solution to power up the facility. I look forward to going through your creator's weapons schematics and summoning them to try it." WuYan expressed his desire.
"Negative. Summoning the weaponry of my collectors would be fatal for your body as it requires a tremendous amount of energy. Besides, I had scanned the Fire Lance into the P.A.N.D.O.R.A. database so the next time when you summon it, it will appear in full and functional." She said,
"Well, that's a convenient system. What else can it do?" He asked
"P.A.N.D.O.R.A. are abbreviations of P- Personal, A- Access, N- Network,D- Depository, O- Organized, R- Retrieval, A- Archives.Every info about Gods, heroes and weapons schematics are stored inside this system. Longinus also uses this system to summon weapons from the archives. "Ada answered.
"Your creator really likes long abbreviations." He said.
"Anyway, the target is dead. Detected energy began to flow out from its body. Recommendation approach - you could use Longinus to harvest the power to enhance the suit." Ada ignored his words and recommended the next approach.
WuYan heeded the advice and carefully approached the Goblin Lord dead body, fearing that it may reanimate itself and caught him unprepared. With the wounds and damages on his body, any direct attack on him would be the end of him.
When he's near to the giant body, he kicks it repeatedly with a normal force, just enough to check whether it's actually dead or falling asleep.
'Target is confirmed dead. There's no more heartbeat or vital signs left from it. You can proceed without any risk - Ada answered WuYan's concern.
'Alright, now I am standing beside the body. What should I do now to harvest its energy?'
WuYan asked while circling around the dead body.
'Type of energy detected - Yin and Earth. Energy harvesting system activated.'
Ada announced its finding, WuYan's metal arm suddenly illuminated and started to glow softly in white. The lights shone on the dead body, countless flows and threads of energy aura to come out from the dead goblin lord's corpse.
'Whenever you are ready, just close your metal hand to a fist to give the signal. Then I will proceed to extract it.' Ada explained the procedures.
The auras are a mix of dark purple color with dark brown color. WuYan followed Ada's words and closed his hands. The energy resonated and immediately followed the light emitted from WuYan metal arm and entered it. He could feel a sudden surge flowing into and circulating through every part of his body; with new energy acquired, he felt a bit rejuvenated.
'General energy harvested, converting energies to essential nutrients for organic humanoid body consumption. Yin energy - Grade A and Earth energy - Grade D was found among the general energy and filtered out from general consumption. Due to the nature of the host body being organic and in humanoid form, all peculiar energy was temporarily stored inside the body until the perfect conversion method was calculated.' Ada explained her report.
"So…is this normal or not?. WuYan asked.
'It's just a temporary setback, you don't need to worry too much about it. I will research the best method for your body to absorb the energy.' Ada explained the situation.
"Care to elaborate more about it?" He asked.
'To put it simply, the energy harvest system was originally made for my body and the suit so that whenever or wherever we are, we can utilize the energy for our advantage. For this harvest, Yin energy can aid us to be more stealthy while Earth energy can harden our exterior, making us more resistant to any damages or harm." Ada explained the energy characteristics.
"So the reasons that I can't use them now are ?" He asked.
"We can absorb whatever energy that we harvested and utilize those in an instant but an organic human body like yours is different. The moment the energy was absorbed into your body, I had to autonomously prevent your body from absorbing them." She explained.
"So in other words, I can only absorb pure energies but those special ones will be stored away until a formula is created? He asked.
'Precisely. We are unsure of the effects and consequences if your body absorbed them. Because of this, I must create the most efficient formula to convert it.'She said.
"Alright but what are all those grades? I heard grade B for Yin energy and grade D for Earth energy." He asked.
'Energy purity grade. From the highest grade, rank S to the lowest grade, rank F. Each rank determines its purity and concentration that will aid us in different scales. So naturally, the purer the energy, the greater the power boost.' Ada explained.
With no more energy left circulating inside the corpse, it begin to decompose quickly and visibly
to WuYan eyes. Except the bones, its skin and muscles melted away in a sticky liquid form. It was only when the corpse was fully dissolved, he saw a round pearl in the center of its ribcage.
WuYan walked toward and picked up the item. Despite still standing inside the deepest cave and surrounded in pitch black darkness, his night vision system allows him to look clearly at the item. Although the lack of light had made him unsure what color the pearl was, he saw within the pearl, there's a cloud of smoke and will move whenever he turns or moves the pearl.
"Do you know what this is, Ada?" He asked.
'My creators called them energy gems. It's a very rare item that only a few were found and kept by the creators. Due to its intense power stored within and hard to break to harness it, along with my creators are busy dealing with the war, till now there's no actual formula or device that allows us to tap into those energies.' Ada replied.
"Well, no harm in bringing it back. Perhaps someone will know about it."
He put the pearl into the pocket and saw his right mechanical arm had almost finished repairing. He raised his arm then opened and closed his hand in repeat. WuYan is impressed with the fast recovery progress.
'Mechanical arm repairs were completed faster with the intake of general energy. Initiate biological arm camouflage.' Longinus reported the status.
"Do conceal the combat suit and helmet. We are exiting this cave and I hope not to bump into anyone with those gears on me. " WaYan ordered.
'Order received. Concealing the suit and helmet.' The Longinus then proceeded with WuYan demand and hid those by turning them invisible then hid underneath his clothes.
