However, unlocking these technical levels is a prerequisite, and some technologies also require theoretical conditions.

For example, if you want to learn nuclear fusion technology, you must first add some nuclear fission technology. To learn material compression technology, you must first learn high-strength compression materials, mass-energy storage technology, and the iron barriers of the combat system.

Although Li Lin already knew the design drawings of the "miniature nuclear fusion reactor" and some nuclear fusion theories, he still lacked overall technical theoretical knowledge.

What's more, these technologies are the prerequisites for subsequent more powerful technologies, so he still needs to spend skill points to learn them.

Fortunately, this kind of science and technology only requires one point to reach the maximum level, and does not require continuous addition of points like some probability-based or consumable skills.

Li Lin will first spend 5 skill points to learn the "LAN connectivity", "mechanical principle analysis", "intelligent AI", "intelligent chip" and "electromagnetism" that he can currently learn.

In an instant, countless knowledge burst into Li Lin's brain, and the feeling of headache made him almost fall off the sofa to the ground.

After a long while, he recovered and stretched out his trembling hand, picked up the teacup on the coffee table and took a sip of water.

"Hiss—it almost exploded my brain..."

Putting down the teacup, Li Lin rubbed his temples, which were still slightly swollen and painful, with lingering fear.

With this experience, he didn't dare to add a little at a time and chose to take it slowly.

The Inventor class also has a "Rapid Assembly" skill, which can be added by one point every 5 levels starting from level 15. It can consume mana to quickly assemble mechanical parts into the shape you want.

For a mechanic, this is a magical skill!

In some situations where it is inconvenient to wear power armor or bring a storm robot, he can just carry enough parts.

When encountering an emergency, he only needs to use this skill to quickly assemble the mechanical device he wants to deal with the emergency.

He is currently level 35 and can upgrade it to lv5, spending a total of 5 skill points.

Similarly, the basic skill of this category, "Mechanical Soul", which was previously upgraded to level 1, has now been upgraded to level 5, costing 4 skill points.

The speed and quality of his mechanical devices have now been greatly improved.

The Inventor family still had many technologies that made Li Lin jealous, but his level was not high enough now, so he could only feast his eyes on them.

"These skill points aren't lasting long! I finally managed to save up 60, but now I only have 27 left. The Inventor category alone consumed 29..."

Li Lin shook his head and sighed helplessly, controlling the [Skill Panel] to switch to "Combat System".

The basic skill "Battlefield Ruler" is a must-have, which can increase the production speed of war machinery, the radiation control range and the power of accompanying combat machinery, and this core skill does not consume additional skill points.

Li Lin suddenly discovered that this skill actually had a bonus on the Inventor's "Rapid Assembly".

The level 5 battlefield ruler has a 200-meter mechanical control range, and the range of the rapid assembly skill is also improved, but the longer the distance, the more mana is consumed.

He was very glad that he had chosen the Ascension Amulet from the treasure vault of the City of the Sun.

With his current mana of 6722 and a maximum mana recovery rate of 5% per second, assembling machinery over long distances is not a problem at all.

After a small moment of joy in his heart, Li Lin returned his attention to the [Skill Panel].

The technologies of the "combat branch" are basically related to dangerous technologies and weapons in the heavy industry and battlefield operations.

Modular Engineering: Optimize the mechanical device construction process, using modular design to reduce current construction costs and time (Prerequisite: Level 15).

[Assembly Algorithm Level 1: Increases the speed of assembly and construction of pipeline modules by 20% (Prerequisites: Level 15, Intelligent AI, Intelligent Chip Technology, Modular Engineering).]

[Precision Manufacturing lv1: Assembly line mechanical devices will always produce high-quality products, with a 30% chance of rare products and a 1% chance of artifact products (Prerequisites: Level 15, Assembly Algorithm).]

[Ultimate Overload Lv1: Consumes 500 mana points, forcibly puts the mechanical device into an overload state, greatly improving the mechanical attributes (Prerequisites: Level 20, Mechanical Mastery, Mechanical Affinity).]

[Mechanical Network Sharing: Establishes a shared network for all mechanical devices equipped with intelligent AI or intelligent chips. The range depends on the skill level of the battlefield ruler (prerequisites: Level 25, Intelligent AI, Intelligent Chip).]

[Ultra-Remote Control: Temporarily overloads the shared network device, extending the radiation control range by 3 times for 2 hours. After use, the shared network device will be damaged (Prerequisite: Level 25, Mechanical Network Sharing).]

[Intelligent Mechanized Engineering Unit: Create an engineering unit to produce mechanical devices and mine minerals, reducing the cost of mechanical construction and increasing its durability (Prerequisite: Level 30, Mechanical Network Sharing).]

[Unmanned Combat Aircraft Swarm: Short-range coordinated combat drones with high speed, small size, and strong penetration survivability (Prerequisite: Level 30, Mechanical Network Sharing).]

[Station Shield: Consumes 30% of maximum energy to generate a force field shield, immune to all damage types, lasts 20 seconds, cooldown time is 30 minutes (Prerequisite: Level 35, Electromagnetism).]

[Gauss Electromagnetic Machine Gun: The electromagnetic projectile uses magnets to accelerate armor-piercing projectiles to extremely high speeds (Prerequisite: Level 35, Electromagnetism).]

[Synchronized Fire Mode: Cross-linked weapon systems fire staggered salvos, significantly increasing the damage of mechanical devices (Prerequisites: Level 35, Electromagnetism, Mechanical Network Sharing).]

Li Lin was stunned when he saw the skills of the combat system.

Even if he had learned Iron Barrier and Battlefield Ruler in advance, his remaining 27 skill points were not enough to learn all of these skills, but he was extremely envious of these technologies.

Whether it is improving the speed and quality of production of assembly line machinery, or mechanical networks and unmanned intelligent machinery, they are all required learning content.

In desperation, Li Lin spent 22 skill points to learn these skills and techniques one by one. He only upgraded "Assembly Algorithm", "Precision Manufacturing" and "Mechanical Overload" to level 1, and just used up all his skill points.

Next, his attention shifted to the individual enhancement branch.

This skill tree category is almost all related to mechanical modification and genetic modification, and in addition to the prerequisite core basic skills, each skill requires 3 skill points.

Li Lin's skill points are now running out, so he can only give up for the time being.

His thoughts returned to reality. He glanced at the clock in the corner of the room and sighed.

"Huh—there's a skill point bonus for creating a mechanical device for the first time... I have to quickly develop new technology."
