A few days later, at Tianshu Underground City.
Lin Mo stepped off the elevator platform and reached the surface.
He looked up at the enormous thing piercing the sky.
Three thousand meters!
The World Tree had grown past three thousand meters!
Even excluding the thousand-plus meters of trunk underground, the visible trunk above the surface stood nearly two thousand meters tall.
Its crown was even more staggering.
Six thousand meters across, the crown spread like an open umbrella, completely covering the surface area of Tianshu Underground City.
A pale green glow seeped through the leaves, strikingly bright against the gray nuclear dust outside.
"Those proportions..."
Lin Mo murmured to himself.
Liu Chengen came to his side and said,
"A banyan's crown can be 1.5 to 3 times the size of its trunk. The World Tree's ratio is only two to one, so that's fairly normal."
"And look at the trunk. It's still thickening."
Liu Chengen pointed at the enormous main trunk, already over a hundred meters in diameter.
"We expect the crown to keep expanding over the next few years."
Lin Mo's mouth fell slightly open.
"It can get even bigger?"
Liu Chengen chuckled.
"Of course. It's nowhere near its limit yet. Although we've accelerated its growth with nuclear fission, it hasn't had much time."
Brimming with excitement, Lin Mo took a deep breath. There was no acrid smell in the air.
Instead, it was as fresh as a forest after rain.
The nuclear radiation levels had long since fallen into the safe range.
According to the tests, people would suffer no harm as long as they remained within the World Tree's coverage.
A rumbling came from the distance.
Construction vehicles drove out of the elevator shaft one after another.
Bulldozers, excavators, transport trucks...
A dense convoy assembled beneath the
