[Mechanical Engineer Lv1: Stamina +1, Intelligence +3, Machinery Affinity +1.5%, gains 2 free attribute points, gains 1 potential point]

[You have comprehended the skill [War Machine Mastery]]

[You have comprehended the skill [Rapid Ordnance Maintenance]]

The Mechanical Engineer has a chain reaction with the Mechanic class. The skills and attributes fit the Mechanic's system itself, almost equivalent to half a main profession. The levels occupied by this type of secondary profession are not considered a waste of value.

As the name suggests, the siege engineer is an intelligence profession, without combat skills, but it is more useful to a Mechanic than combat skills. Ordnance refers to war machines, such as guns, armor, shields, etc. This secondary profession will have additional bonuses when manufacturing and using war machines.

Han Xiao had a pile of experience points in his waist. With a wave of his big hand, he directly upgraded the two skills to max level.

[War Machine Mastery Lv10: When using war-type machines, gain an additional 18% attack and defense bonus]

[Rapid Ordnance Maintenance Lv10: When repairing war-type machines, speed +24%, and during the repair process, randomly restore 3~6% durability. Trigger chance depends on intelligence attribute, unlimited number of times]

These two skills have simple and crude effects, and they are quite useful to Grand Technician Han, but he acquired this secondary profession mainly for the expertise after reaching the maximum level.

He directly spent more than 90 million experience points to upgrade his secondary profession to the maximum level.

[Mechanical Engineer upgraded to Lv10 (max), Stamina +1, Intelligence +3, Machinery Affinity +1.5%, gains 2 free attribute points, gains 1 potential point]

This secondary profession gave him a total of 10 Stamina, 30 Intelligence, 15% Machinery Affinity, and 20 free attribute points and 10 potential points. If the new skills at max level are added, there are a few more potential points.

Han Xiao's Intelligence attribute reached 391 at this time. He put all the free attribute points into Intelligence, breaking through the 400 mark required for class advancement.

When Mechanical Engineer reaches the maximum level, like the Nightstalker, a new expertise appears.

[You have comprehended the skill [Militarized Modification]]

[You have gained the expertise – [Ordnance Mass Production Insights]]

[Militarized Modification Lv10: When manufacturing or modifying combat machines, equipment basic attributes +8%~14%. (Note: This bonus is calculated separately and is unrelated to enhancement modification)]

"This is equivalent to an additional strengthening bonus, mediocre." Han Xiao nodded and looked at the newly acquired expertise, which was the goal he valued.

[Ordnance Mass Production Insights: You have new insights into mass production engineering. When manufacturing war machines, assembly line success rate +30%, production line quality +10%, material cost -18%, mass production speed +20%]

Mass production bonus, this is the essence of this secondary profession!

There are several milestones in the Mechanic's growth stage. High-speed assembly during combat is one of them, which is one of the reasons for the rise of the Mechanic's 3.0 version. And assembly line mass production is a later milestone. Mass production is a necessary ability for the Mechanic's most violent and kryptonian playstyles, "Legion Stream" and "Zerg Rush Stream".

Normal Mechanics use high-quality weapons that are carefully enhanced, while mass-produced creations are "consumables" with relatively low quality. As mechanical technology improves, the gap between different qualities becomes larger and larger, but quantitative change can accumulate into qualitative change. Those scattered bonuses, the results shown through mass production, will be vastly different.

The Mechanic and Magic classes are two professions that benefit greatly in the later stages. The Mechanic's Legion Stream and the Magic's Summoning Stream can turn a one-on-one fight into a group fight, which is very disgusting. Almost all players cannot resist a wave rush of these two combat styles, and the game experience is extremely poor.

However, these two streams are strong, but they have great limitations. The reason is obvious - they are very expensive! Mass-producing a mechanical legion is an extremely terrible expense for players. Moreover, by that time, all players' individual combat capabilities are strong enough, even if the Legion Stream can drown the opponent with a sea of people, their own legion will suffer a lot of losses. If they participate in the league, after rounds of battles, the Legion Stream's own combat power is always in a downward state. The legion accumulated for a season may be wiped out after ten or twenty games. This is the real lack of persistence.

If the Legion Stream encounters the Legion Stream, oh, that would be too refreshing. In a wave of team battles, the scene is grand, the audience is happy, but the two sides fight until there is nothing left, and all their family wealth is exhausted.

Therefore, in his previous life, the Legion Stream and Zerg Rush Stream were called "legendary" streams, rarely seen. If you see this kind of player, you must cherish him, after all, they may defect at any time...

Han Xiao analyzed that the players are relatively weak now, and he can flex his muscles and ravage them personally. When the players' lethality becomes stronger and stronger in the later stage, and various strange abilities emerge one after another, he doesn't want to take too much risk, so developing the Legion Stream is an inevitable choice, even if it is used as a trump card.

What, the Legion Stream is very expensive?!

In the eyes of Grand Technician Han, a problem that can be solved with money, is that even a problem?!

Especially since this expertise can also reduce costs. Seeing these four characters, Han Xiao felt as if he had drunk a cup of hot water, feeling comfortable all over, with rich nutrition, and curing all kinds of difficult and complicated diseases.

Han Xiao has a long-term growth plan. Although he hasn't learned the knowledge of assembly line yet, he will get the useful expertise first.

His total level reached level 80, which also met the advancement requirements. The level 80 advancement mission is to sacrifice 60 million experience points, which is simple and crude. Han Xiao couldn't help but breathe a sigh of relief. The advancement mission he randomly received this time was considered very easy.

In version 2.0, the level cap is level 90, while in version 1.0, the level cap is level 60. Players in version 1.0 did not know about the advancement mission because they could not level up, which shows that players in version 2.0 need to experience two advancement missions at level 60 and level 80, and the level 60 advancement is a key watershed for racial sublimation, so the level 80 advancement is relatively smooth.

However, the so-called "simple" is only according to the standards of Grand Technician Han. It takes a long time for players to accumulate 60 million experience points. He only spent more than 90 million experience points to go directly from level 70 to level 80. How can players be as rich and capricious as Grand Technician Han? They can only grind up level by level miserably. The significance of this amount to them can be imagined.

Moreover, sacrificing these experience points is almost equal to no income, and this kind of advancement requirement will make players very blue and thin (sad).

Han Xiao was in a happy mood, and thought to himself: "Now there are only the last two advanced mechanical knowledge items left. As long as this job earns enough money, I can go back to my hometown and get married... Bah, I can go back and advance to a new main profession!"

After leaving the bar, Han Xiao and Lerden strolled on the streets of Senyuan City.

The sky was full of stars, and the soft, gauze-like starlight draped over their shoulders. Although the environment of this planet is dangerous, the scenery is beautiful.

The dark green distant mountains, the verdant forest sea, as if the breeze dyed with greenery brought the rustling sound of leaves, and the dazzling Milky Way that existed forever above their heads. Back then, when the Sunil refugees were moved to this planet by Godora, perhaps they were attracted by the natural environment here.

Han Xiao shook his head and couldn't help but think of a famous saying that was suspected to be from Lu Xun: Dangerous things often have beautiful appearances.

"Where else do you want to go?" Lerden asked.

"Just walking around."

"Then let's go out of the city and go back to the base."

Han Xiao asked: "Don't you have any places to go in the city, such as going home or something?"

Lerden shook his head, "I have no family."

Han Xiao touched his chin and asked, "What kind of mission are you on?"

"Field operations."

"This is the most dangerous job. Your Sunil race's Supers hand over the hard-earned money and have to risk their lives to perform dangerous missions. You are so dedicated and worthy of being a race of heroes."

Lerden's eyes were a little complicated, he wanted to say something but stopped, and finally shook his head and said nothing.

This expression was captured by Han Xiao, who was secretly delighted. His probing got the information he wanted.

"If I guessed correctly, the Sunil race's plot already exists..." Han Xiao's eyes narrowed slightly.

The employment mission is not the main goal of this trip, Han Xiao has another purpose.
