In Lü Yongchang's mind, this branch of the technology tree should end here.

But just now, when he focused all his attention on the cursor, he was surprised to find that above the cursor, there was a faint white line!

The thin line stretched straight to the top of the sixth-level civilization's technology tree, where it intersected with another thin line, forming an extremely dim cursor.

The text on the cursor was very blurry, and Lü Yongchang tried for a long time but still couldn't see it clearly.

But he could imagine that it was definitely another killer weapon!

As a long-time sufferer of the phobia of insufficient firepower, Lü Yongchang silently made a decision in his heart.

Starburst technology must be mastered as a priority!

Only in this way could he glimpse that blurry, dim cursor!

Of course, he did not forget his main purpose—to determine the dividing line between Type V and Type VI civilizations and guide human civilization in the most correct direction of development.

So he finally turned his attention to the bottom of the technology tree.

Those were several cursors of varying brightness.

The bottommost cursor has several thin, bright white lines at its base.

These thin lines extend towards different cursors: [Curvature Technology], [Grand Unified Theory], [Elementary Spacetime Theory]...

The text on the cursor is very clear.

[Preliminary Application of Spacetime Theory: Space Weapons]

Then, several thin lines extend from this cursor, each pointing towards a different cursor.

The nearest cursor is located directly above it.
