After each world is over, the system will give Liu Ling a period of time to rest (wan) and adjust (le). So far, Liu Ling doesn't know how long the single-time limit is, and the system pretends to be mysterious and does not tell him.

It was only during this period that Liu Ling could truly sit down and think about and review the experiences of these two worlds. "It seems that the driving skills of C-class are not enough..." In an ordinary world, pilots with C-class skills may be comparable to an ACE, but if the difficulty of the world itself increases, once they come to a world of wars (such as the Century of the Universe), maybe a recruit who has participated in one or two battles, or even just graduated from the non-commissioned officer school (@Trlington Base) may have this level of technology. So, he felt it was time to upgrade his skills.

Various skills, including driving technology, have three stages in each level: acquisition, internalization, and preparation for upgrading. Acquisition, as the name implies, is a state of acquisition or awakening from the system; internalization is a state where the knowledge or skills are transformed into a part of oneself, so that one can use it at will; preparation for upgrading is a state unique to the growth skill - starting from the acquisition of skills, the understanding and application of skills will be transformed into a numerical "experience value", and once the experience value is full, you can prepare to upgrade it to the next level. Some bloodlines will also have this magical state, but there is no "experience bar" that can be numericalized cognition for reference.

As CODE in charge of a world, Liu Ling can still do it if he wants to accumulate experience through combat.

When this upgrade task finally ushered in the most critical step, it was already three days later. During these three days, Liu Ling and Xuefeng were practicing day and night. No one knew how they practiced and how much experience they had accumulated (in various senses). As can be seen by others, their relationship seemed to be one step closer.

Due to Liu Ling's whimsical creativity and the assistance of Xue Feng, his driving skills are unique and unique, so he is also a unique and powerful driving technology in the C-class, so he is rated as C+. This also leads to his driving skills that allow bodies with B- and below to perform 110% performance (theoretically), but because the C-class technology is slightly rougher than the B-class, when he drives the B-class body, he can only show 80% of the performance.

Any technology in the aircraft war zone, from full analysis/maturity to formal production, requires a lot of funding support - and without material reserves, the so-called funding is points. Although Liu Ling seems to have a lot of points, based on the principle of "all technology must be in his own hands", the remaining points are not suitable to buy a new body - not to mention, what should Xuefeng do if there is a new body? Therefore, Liu Ling decided to use the points to strengthen Xuefeng and himself.

"Upgrade the 'General Body Driving Technology'." Liu Ling grabbed a tube full of shiny light spots (points) in his hand and inserted it into the skill box marked "C+ General Body Driving Technology". The shiny particles flowed into the "C+" like flowing water, so the letter began to turn into a ball of golden liquid, and finally condensed into a "B".

Since his technology was already C+ and had been internalized, Liu Ling's assimilation progress of the newly acquired knowledge was also very fast, and the experience bar naturally began to grow.
