The apartment complex he bought was just one street away from the one where his senior brother lived. Both were located in the core area of ​​the city center. However, Jiang Huan rarely appeared in the city center, so Shen Qian had not yet met him there.

There are only three households on each floor. Shen Qian's other two neighbors on the top floor are, firstly, the daughter or lover of a certain nobleman, though Shen Qian is not quite sure about this; and secondly, a top-tier expert from abroad, through whom Shen Qian has met many people here.

Shen Qian, after taking the elevator upstairs, didn't rush home. Instead, he went straight to the mailbox by the door, where, unsurprisingly, there was a metal box about two meters long and wide with Shen Qian's signature on it.

Upon entering the house, in the spacious corridor, Chen Qian sat cross-legged, touching the cold, hard material of the box, and then glanced at the upper right corner.

The military industry officer looked up, exclaimed "That's fast!" and then tore off the seal, finding the fingerprint verification port.

Click!

The lock on the box popped open, and at the same time, an extremely cold aura emanated from the box. Accompanied by a slight hissing sound, hundreds of grooves about ten centimeters deep appeared on the walls and ceiling around the corridor, densely packed and shocking to behold.

...Forget that weapons of this caliber inherently possess an uncontrollable destructive power.

Shen Qian quickly closed the box again, feeling somewhat annoyed. Fortunately, although the houses in the underground city were expensive, they were designed for powerful martial artists and the materials used were quite sturdy. Otherwise, if it were an ordinary house, it might have collapsed directly.

Once he confirmed that the sharpness gathered inside the box had dissipated, Chen Qian finally opened the metal box.

Inside the long box, nestled within a soft pad made of some kind of demonic beast's fur, lay a long, bluish-red sword, about a meter long, silently radiating a chilling aura.

Intricate, fine, and exquisite patterns cover the blade, resembling distant mountains and a setting sun. Such a pattern on a sharp blade inexplicably possesses a poetic beauty.

This is the "Mountain and River Blade" after its rebirth.

After Shen Qian paid four catties of Sky-Mending Stones and about 90 million in production costs, and waited for nearly ten days and nights, the "Mountain and River Blade" that was reforged was no longer an A-grade psionic weapon.

"SS+"

Shen Qian picked up the instruction manual from the top craftsman of the Military Industry Department and saw the latest grade assessment of the "Mountain and River Blade". A satisfied smile appeared on his lips.

Psionic weapons are classified from F to A, and then S, SS, and the almost impossible SSS-class psionic weapons.

As far as Shen Qian knew, although SSS-level psionic weapons were divine weapons that even those from the mountains and seas could wield, they were no less rare than star-level weapons, and many kings and nobles were still using weapons of this level.

Therefore, SS+ is almost the most powerful psionic weapon currently available before the sinking, and it is very close to the highest level of SSS.
