My Infinite Investment System

Chapter 73: Evolution

Ryan bought the blueprint before the Exchange could make the offer feel reasonable.

[Spear evolution blueprint I: 900 return credits]

[Purchase confirmed]

[Remaining balance: 100 return credits]

The notice vanished, left his ribs aching, and placed the crowned image behind his eyes.

’That was the last affordable mistake for a while,’ Ryan thought, flexing his injured hand, ’so naturally it had come with a receipt.’

Dara reached for the spear, then stopped when he kept hold of the shaft.

"If you want me to build from that specification," she said, watching the bent locks under his fingers, "you need to let me inspect the damage before the metal cools."

"You inspect it after we leave the water," Ryan replied, sliding the spear into its shortened position, "the station gave us provisional stewardship, and I want everyone who earned it above ground."

The ace kept her blade lowered but did not sheathe it.

"The station accepted your intervention," she said, looking at the regulator case, "that does not make your team the lawful owner."

"We recorded provisional stewardship," Grace replied, sealing the crystal key inside an evidence sleeve, "which is why nobody gets to improve the fact later."

Mika stepped between the ace and Ryan with both tonfas ready.

"We can argue about ownership after the water stops trying to remove us," she said, watching the lower tunnel, "I promise the paperwork will still be tedious upstairs."

The ace ordered a joint retreat until the surface channel, and nobody touched the regulator while they climbed.

Nia met them beneath the exposed arch, took one look at Ryan’s posture, and walked past the crown case toward him.

"How many fingers can you move without making that face?" she asked, closing her hand around his wrist.

"All of them," Ryan said.

"That answer has never improved a medical report," Nia replied, testing the movement with careful pressure, "your shoulder is compensating for the ribs, so you are done pretending the spear is light."

’I had not realized the pretending was visible,’ Ryan thought, lowering his hand, ’which made it less pretending and more performance art.’

Dara set the portable slate on an equipment case after the surface team formed a loose perimeter.

"The specification calls for a telescoping spine, reinforced return locks, storage, and two acceleration routes," she said, reading the diagrams as if they had insulted her personally.

Ryan closed the internal page before the compatibility logic could reach his face.

’The full pattern belonged in Portfolio,’ he thought, easing onto a supply case, ’Dara owned the metal, and I owned the part that made it dangerous.’

"The physical work is yours," he said, resting one hand on the damaged shaft, "the blueprint gives you structure, and I handle what refuses to stay on the page."

Dara raised her eyebrows while considering the diagram with open suspicion.

"You will stand nearby and complain when the tolerances move," she said, passing him a marked section, "which is the closest you get to helping."

Mika lifted her camera toward the work cases and checked the framing twice.

"The surface team wants proof that Dara built the new spear," she said, keeping the lens away from Ryan’s expression, "so please avoid looking mysteriously funded for ten minutes."

The first assembly consumed two hours plus three replacement sleeves, because Dara rejected every lock that tolerated the old stress pattern and refused to let the public demonstration become a workshop apology.

Dara cut away the old locks, fitted the matte-black spine into its housing, then rebuilt return storage beneath the grip until the weapon could take force without passing each mistake straight into Ryan’s shoulder.

Gold and pink channels appeared beneath the dark surface after the final section clicked into place.

"People remember unusual equipment," Grace said from behind the camera line, "and remembered equipment attracts tests."

"Then it should pass the first one," Ryan replied, though his shoulder had started offering opinions.

Mika uncovered both tonfas and moved closer to the new grip.

"The blueprint shows a synchronization route through conductive weapons," she said, keeping her hands visible, "I can give one restrained imprint if you want the test."

Nia folded her arms over the medical kit and waited for Ryan’s answer.

"Define restrained," she said, looking at Ryan rather than the weapon.

"One timing pattern through the tonfas," Mika replied, "no stored charge, no borrowed technique, and no control after the imprint ends."

"If his shoulder compensates," Nia said, "I stop the test whether he likes it or not."

Mika turned to Ryan and lowered one tonfa toward the ground.

"Your choice," she said, "and I am not offering this because the weapon needs my permission to exist."

’She was giving me a boundary before giving me power,’ Ryan thought, meeting her eyes, ’that was the part I could not afford to misunderstand.’

"One imprint," Ryan said, looking toward Nia, "and you stop it when she says stop."

Mika nodded, then placed the tonfas against opposite sides of the grip.

The first pulse moved cleanly through the black housing without heating the grip.

Ryan matched the rhythm and sent the return command through the storage chamber.

The new spear snapped open far too quickly for Ryan to brace.

Its forward section struck stone beside his boot while the return lock kicked backward through his shoulder.

Nia slapped both tonfas away from the grip before Ryan could turn the stumble into a fall.

"Stop," she said, catching his elbow, "the test is over until your body quits volunteering as the missing hinge."

Mika caught the spear before it struck the equipment cases beside Dara.

"I asked for consent, and I received it," she said, keeping the camera pointed down, "but consent did not make the timing safe."

"The imprint is not transferring skill," Ryan replied, pressing his good hand against his shoulder, "it exposes a rhythm the weapon cannot hold yet."

"Useful diagnosis," Dara said, turning the damaged lock between two fingers, "less useful timing."

’The attempt had bought information,’ Ryan thought, watching the bent metal, ’the information had still charged interest in cartilage.’

Nia taped his shoulder and sent him away from the assembly table while Dara replaced the lock.

Mika ran controlled pulses through an empty practice sleeve as Grace marked each brightening channel on the recording.

"The weapon reads the handoff as an attack," Grace said, pausing the frame, "so it opens against the source instead of accepting the transfer."

’It was not refusing Mika,’ Ryan thought, lifting the practice sleeve with his left hand, ’it was refusing the moment I asked it to trust a second rhythm.’

He rebuilt the motion until the return lock settled before Mika touched the sleeve.

After the return lock settled cleanly, the second drill opened three sections without kicking back through Ryan’s taped shoulder.

A third drill held the gold line inside the shaft without throwing the lock or forcing Mika to pull away.

The new lock failed before the weapon did, which Dara described as progress while recording a repair estimate.

On the sixth attempt, Mika sent one restrained pulse through the tonfas.

Ryan accepted it through the grip and the spear telescoped forward before returning to his hand.

Gold marked the thrust while pink marked the retreat, leaving a narrow scorch across the practice target.

The surface team reacted before Grace could lower the camera.

"Compound spear," a recruit called, staring at the black-and-pink line.

Mika looked into the live lens.

"That is better than spear guy," she said, tapping one tonfa against the housing, "and I am taking credit for the name."

"The craftswoman built it," Ryan replied, balancing the weapon across his knees.

"The object belongs to me until the invoice clears," Dara said, shutting her tool case, "and the nickname can pay for repairs."

Grace ended the stream after it caught the return snap, Dara’s work, and the target splitting along the scorch.

The public saw Dara’s weapon take a new name on camera.

Ryan saw a private compatibility pattern settle into Portfolio where nobody else could reach it.

’A visible return needed witnesses,’ Ryan thought, locking the spear into storage, ’otherwise it was just a private number wearing expensive metal.’

The ace approached after her escorts secured the regulator in a guarded case, keeping the black receiver held away from both the evidence team and the wet stone underfoot.

"A neutral clinic channel reached my device," she said, holding out a black receiver, "the message concerns your continued availability."

Ryan took the receiver carefully with both hands, avoiding the active display panel while Grace kept the evidence camera trained on the handoff.

The message carried a committee seal, a contractor routing mark, and a timestamp from the neutral clinic server.

{Render Ryan Keller operationally unavailable before the committee vote. Injury, detention, disappearance, or death satisfies the order.}

Mika’s expression changed before her hand reached for the nearest tonfa, then she forced her fingers back around the grip without drawing it.

"That is a kill order," she said, reading the preserved display.

"It is an operational order written by people who prefer legal language," Grace replied, studying the routing mark, "the clinic channel authenticates it, and the neutral sender gives us a preservation path."

Ryan returned the receiver to the ace under Grace’s recording lens.

"Then we preserve it," he said, feeling the new spear rest against his palm, "and we stop treating the committee vote as the next event."

The distant stream had already started repeating the name Compound Spear.

’They had priced the cost of leaving me alive,’ Ryan thought, watching the receiver disappear into evidence custody, ’now they could learn what that price bought them.’
