The Hulkbuster Armor's left shoulder hung in midair from a mechanical arm.
It did not settle directly onto Chen Mo.
The Iron Exoskeleton closed around him from behind first, locking into place layer by layer along his waist, back, and shoulder blades. Only after the Load-Bearing Frame formed a complete ring was the shoulder armor, weighing several tons, slowly lowered into its socket.
The Mechanical Spider Legs behind Chen Mo remained folded.
Weight like this could not be left to four independent connecting shafts.
When the mechanical arm released the Hulkbuster shoulder armor, a crack split the floor beneath Chen Mo's feet.
He did not fall.
The two Tonys stood on opposite sides of the Control Console. One adjusted the weight distribution between left and right, while the other rearranged the Thrusters. Reed fed the deformation caused by each application of force into the model.
Peter knelt in front of Chen Mo and fastened the last securing strap.
The entire laboratory was preparing for one person.
Some of the strongest people on both Earths had already tried their own methods.
Thunder, magic, Infinity Stones, and energy powerful enough to propel starships had all stopped outside the Spatial Interlayer.
They could not touch that place.

For the second test, two suits of Iron Man Armor pulled the spider silk in opposite directions. The silk held, but the clasp securing its cartridge flew halfway across the laboratory.
On the third attempt, the exoskeleton finally
