Technological advancement begins with devouring.

The second-floor library is much larger than the first floor, and the number of books on the shelves is several times greater.

The Alchemy Technology area alone contains more than three times the number of books found in the first-floor library.

Jiang Chen couldn't possibly read the whole book in a short time; he only glanced at the table of contents and got a general idea of ​​the so-called "alchemy technology."

The so-called "alchemy technology" is actually very similar to the "alchemy" in many fantasy works that Jiang Chen has come into contact with, and it exists in many worlds.

Its core is to analyze, deconstruct, recombine, and reconstruct matter, so that one substance becomes another completely different substance.

Alchemy was originally created to produce gold from inexpensive materials.

However, this path did not work in traditional technological civilizations. Instead, alchemy has developed remarkably in many worlds involving mystical forces, and there are even powerful civilizations that have been established with alchemy as their core.

The powerful alchemy is almost like having the power of a creator, capable of creating everything.

However, at least within the second-floor library, the level of alchemy technology is clearly far from reaching that level.

But after just a cursory glance, Jiang Chen judged that the combination of alchemy technology and traditional technology would definitely produce miraculous results.

Of course, to achieve sufficient success on this path, investment of time and energy is essential.

Even within the traditional technology field, Jiang Chen's achievements are mainly concentrated in a few areas such as machinery, electronics, information, and energy.

They haven't really put much effort into fields like genetic engineering and biochemistry.

At least in the short term, Jiang Chen will still focus on mechanical and electronic fields.

As for alchemy, it will at most become a supplementary technology.

Of course, if he has enough time and energy in the future, Jiang Chen still plans to master as many different systems of technology as possible.

But that's for later.

Instead of rushing to acquire new knowledge, Jiang Chen exited the library and opened the [Specialty] option.

243 skill points are enough to exchange for some relatively powerful abilities.

Originally, Jiang Chen had saved these skill points in the hope that he could exchange them for a skill that could quickly enhance his combat power should a powerful enemy appear.

However, after entering the planetary level, Jiang Chen was no longer so eager to improve his personal combat power.

On the contrary, specialties like "high concentration" that accelerate personal growth have higher value in the long run.

The system offers a large number of specializations, but Jiang Chen cannot afford to exchange for most of them.

After searching, Jiang Chen selected a few that suited his taste.

【Mechanical Affinity】: You gain an additional attribute 'Mechanical Affinity'. The base Mechanical Affinity attribute value is equal to the Intelligence attribute. Each point of Mechanical Affinity will increase the attributes of the mechanical creations you control by 1%.

The exchange requires 111 specialty points.

[Brain Enhancement]: Increases intelligence attribute by an additional 5%.

The exchange requires 88 specialty points.

[Scholar's Mindset]: When learning and mastering new knowledge, each point of Intelligence attribute increases learning efficiency by 1%, and each point of Spirit attribute increases learning efficiency by 0.5%.

The exchange requires 199 specialty points.

[Mass Production Experience]: Success rate of assembling on any production line increased by 50%, mass production efficiency increased by 20%, and production cost decreased by 20%.

The exchange requires 222 specialty points.

With his four specializations, Jiang Chen currently has enough skill points to exchange for either [Mechanical Affinity] + [Brain Enhancement], or to exchange for either [Scholar's Mindset] or [Mass Production Insights] separately.

The three options correspond to the combat effectiveness of mechanical creations, the efficiency of acquiring new knowledge, and the ability to mass-produce mechanical creations.

Or to put it more simply, [Scholar's Mindset] corresponds to 'upgrade speed', [Mass Production Experience] corresponds to 'troop production ability', and [Mechanical Affinity] + [Mental Enhancement] correspond to a change in combat style.

In a sense, it involves using boxers or other mechanical creations as one's own telekinetic weapons, and being able to greatly enhance the power of these weapons.

Jiang Chen liked all three options, but he only had enough skill points to choose one.

After hesitating for a long time, Jiang Chen still chose the "scholar's mindset".

Each point of Intelligence increases efficiency by an additional 1%, and each point of Spirit increases efficiency by an additional 0.5%. With Jiang Chen's current attribute points, this is equivalent to an additional 213% increase in learning efficiency, which also means that his 'leveling speed' has increased by more than two times.

This number will continue to increase as your level increases.

Moreover, mastering more and more advanced technologies allows one to exchange for more powerful blueprints from the system, enabling the creation of more powerful weapons, which is also a means of enhancing combat effectiveness.

As the new skill was successfully redeemed, a sudden chill ran through Jiang Chen's mind, making him shudder and giving him goosebumps.

However, this special feeling comes and goes quickly.

Before Jiang Chen could react, it had already disappeared, as if the scene just now was just an illusion.

However, Jiang Chen could clearly feel that his thinking speed had greatly improved compared to before.

"Even without entering a learning state, it's still effective?" A thought flashed through Jiang Chen's mind, and he immediately felt that spending these expertise points was well worth it!

Forcibly suppressing the urge to enter the system library and study more advanced knowledge, Jiang Chen shut down the system and returned to reality.

After glancing at the time, it had taken more than ten hours to break through to the planetary level and to study the changes in the system. It was already the next day.

"It took so long..." Jiang Chen muttered in surprise, opened his communication bracelet, summoned Jarvis, and asked, "Did anything happen during my seclusion?"

“Li Dawei called once, but when the master didn’t answer, he sent an email to inquire about the progress of the [Boxer] modification. That’s all,” Jarvis reported quickly.

Jiang Chen thought for a moment, then shook his head and said, "Don't worry about him for now. Jarvis, I'll give you a new alloy formula. Try using it to replace the shell material of the [Boxer] and create a new experimental model."

As he spoke, Jiang Chen picked up the [Brainwave Access Device] and, through mental input, entered the alloy formula he had just redeemed from the system into Jarvis's database.

“Master, our factory currently lacks the capability to smelt alloys,” Jarvis cautioned. “Purchasing new equipment and manufacturing a new experimental model of the [Boxer] will take at least two weeks.”

"Two weeks...that's fine." Jiang Chen nodded and said softly, "Perfect timing. I also need to demonstrate my strength and join the War God Palace as a planetary-level individual."
