Using strategic resources was out of the question, of course, but despite the enormous consumption involved in Elder Yu and the others' research, Nie Yun had never considered imposing limits.
Returns required investment. The scientists led by Elder Yu consumed an astonishing amount of resources, but their output genuinely satisfied Nie Yun.
At the front, Nie Yun continually devoured all kinds of high-tech equipment and plundered the enemy's technology. In the rear, the scientists broke those technologies down and integrated them into Earth's technological framework, turning them into a technological foundation Nie Yun could truly call his own.
It was precisely this close, complementary cooperation that had allowed Nie Yun's technological level to grow explosively and rapidly approach that of the Twin Stars. All kinds of derivative technologies kept emerging, and the Sword Immortal Mecha was one of them.
Overall, Nie Yun's infiltration plan had already achieved its initial modest goal of making a hundred million...
For Nie Yun, technological advancement meant greater strength, whereas energy did not. Which mattered more was obvious. He did not even need to think about the choice.
Since he could not cut spending, he could only find new sources of income. Thus, Project Prometheus was born!
In the void hundreds of thousands of kilometers from the Sun, a spherical spacecraft slowly flew toward it. The intense solar radiation gave the exposed surface of its bow a faint red glow.
The Sun's core temperature was approximately 15 million°C, and its surface temperature was about 5,700°C. Even at this distance, the spacecraft's surface temperature exceeded 1,000°C under the scorching heat.
With every meter the spacecraft advanced, it had to endure even greater radiant heat. Ordinary materials could not retain their normal properties at such temperatures.
But naturally, this spacecraft's material was anything but ordinary, because
