the joy on Su Mo’s face slowly began to fade, replaced by a heavy seriousness.

Setting aside the manufacturing materials needed by these three types of armor for now, since those could be downgraded and he could simply make it from what he had on hand,

grade-10 alloy turning into grade-3 alloy at most lowered the armor’s ability to resist impact,

and a grade-10 energy machine turning into a grade-2 energy machine would only reduce its speed a little.

At the very worst, such changes shrank performance and would not affect the structural rigidity and key performance of the whole armor too much.

But what was troublesome was the requirement concerning the manufacturing platform.

Take the miniature development platform Su Mo was using now as an example.

Its price was a steep thirty-nine thousand eight hundred points, and its theoretical operating precision reached nearly one three-hundred-thousandth.

Converted into real-world precision for comparison, that was around 0.05 millimeters, just barely reaching the limit of handmade work.

And to make the exploration armor, the precision required was one ten-millionth, which meant the operating precision had to reach 0.0015 millimeters.

Such terrifying fitting accuracy was not only beyond handmade work, but could not even be recognized by the human eye at all.

“In other words, making the exploration armor is out of the question. No need to even think about it...”

He did not know exactly what the precision of the advanced development platforms in the territory was.

But just thinking that an intermediate development platform with one eight-hundred-thousandth precision sold for a full three million trade points,

even selling off all of Zizai Liang Lane, or all of Mulberry Field Town, would probably not be enough to afford one.

“If I push hard and manage to get an intermediate development platform, maybe I could make the assistance mech.”

“But that mech can’t carry combat components, and it’s not what I urgently need right now.”

“So my choice is left with only the combat battle armor, cheap and good, whose manufacturing precision needs to be only one five-hundred-thousandth!”

Back at the original starting point, Su Mo took two deep breaths and felt not a bit of regret.

He could get another blueprint later without any problem.

And the upgrade options would not pop up only once.

The exploration armor, the assistance mech, and even the ghost-energy battle armor, all of which looked amazingly effective, could be upgraded again later when he was richer.

For now, upgrading and building the combat armor to complete his task was what mattered!

His mind made up, Su Mo stood up, went to the door first and checked again and again that nobody was peeking from outside, and only then drew the curtains and returned to his seat.

The next second.

“I choose to upgrade... the combat battle armor!”

As the words fell, 25980 was deducted directly, and lines of green light began to extend outward from his body, scribbling and drawing.

On the blueprint, the original handwriting began to be erased and revised, and the corresponding part diagrams started to jump and transform.

At one moment, Su Mo seemed to have an illusion before his eyes.

He seemed to see thousands upon thousands of himself, lying on a huge square, communicating, talking and drawing without pause.

The faces of these little figures were exactly the same as his, and even their clothes were not much different.

Every time they finished communicating and talking it over, one more stroke of writing and one more part appeared on the blueprint hanging in the center of the square.

From day to night, from black hair to white hair.

In this place, time seemed to lose its meaning, and everything was left with only that blueprint.

Calculations repeated in cycles, tedious and dull reconstruction. He saw the selves in the square collapse one after another, saw corpse after corpse begin to rot, oxidize, and in the end turn to ash.

For some reason, having put himself into it, Su Mo felt not a trace of sadness. Instead, an unprecedented surge of excitement rose in him!

In a trance, time slipped away bit by bit.

The old little figures grew old and vanished, and new little figures hurried in to fill the gap.

Like the Foolish Old Man moving the mountains, the huge blueprint in the center of the square also slowly began to be filled in and made solid, bursting with waves of golden light.

“It’s done!”

Watching the last blank part of the progress get filled in, a glint of joy flashed in Su Mo’s eyes.

The next second, he was kicked out of this mysterious square space and back into the bright workroom.

Before his eyes,

the blueprint lying on the table had clearly undergone earth-shaking changes compared with before.

“Completely different from the earlier upgrades!”

“It feels as though countless versions of myself completed this learning and designing from beginning to end!”

On the blueprint, every revised stroke matched perfectly with what Su Mo himself had written before.

The design style of each part also quietly fit Su Mo’s own sense of beauty.

This unusual way of upgrading filled Su Mo with wonder, and he wished he could do it once more and savor the marvel he had just felt.

However, after only a few seconds, this odd thought was thrown to the back of his mind again.

After all, compared with this, the upgraded blueprint was obviously the main event.

“Good! Good! Good!”

He browsed through the blueprint from beginning to end, and Su Mo could not help repeating his praise.

He could not fully understand the upgraded blueprint now, limited by his insufficient level of knowledge,

but the system had thoughtfully provided the complete manufacturing method, almost like a foolproof guide!

“Huh, it wants me to name it?”

After a scan, he looked at the naming page that suddenly popped up.

Su Mo gave a light laugh and, almost without hesitation, typed in the name he had prepared earlier.

“From now on you are...”

“Sun-chaser Type One!”
