The grand unified theory.
In the universe-at least, the universe as human civilization currently understood it-there were only four forces acting between microscopic particles.
Universal gravitation, electromagnetic force, the strong interaction, and the weak interaction.
From humanity's departure from Earth to its development into a level four civilization, the Academy of Sciences had unified only three of those forces.
Universal gravitation had remained outside human civilization's theoretical framework because gravitons had never been discovered.
Now that the Academy of Sciences had gained control over gravitons, work on the grand unified theory had reached its most critical step.
The half-dim, half-lit icon in the Technology Tree System confirmed this.
They were just one final step away from presenting the grand unified theory to everyone!
Analyzing a key technology from a higher civilization level was an extremely dangerous undertaking.
In the past, Lü Yongchang would never have dared take that risk.
But now, after his brain had undergone quantization,
with his thinking capabilities vastly improved, he decided to take the risk.
The Human Fleet had little time left.
Under the Technology Tree's guidance, Lü Yongchang's brain entered an overclocked state once again.
An endless stream of inspiration surged up from the depths of his mind.
Along with it came a dizziness he had not experienced in a long time.
He endured the dizziness and rapidly sorted through and integrated all the information he had.
A mathematical model took shape in his mind, little by little.
While Lü Yongchang devoted himself to cracking the grand unified model, He Bilin returned to the laboratory after a brief rest.
According to Lü Yongchang's instructions, he was to lead his team in developing gravity shield technology.
"A curvature bubble..."
His brow slightly furrowed, He Bilin studied the spacetime model Lü Yongchang had left in the
