After returning to the upstairs lab, Loren no longer appears.

It was the turn of the academy to take two days off after ten consecutive days of classes, and he locked himself in the laboratory, and did not take the opportunity to go home, but concentrated on refining high-grade metals, and at the same time constantly replenished the consumed mana energy by absorbing the leyline spiritual energy.

In the process, Loren refined a large amount of starter culture and powder quartz, and refined a large number of high-grade metals such as syrup, sign, and pang.

In order to avoid arousing the suspicion of the other students, Luo Lun did not swallow the third tonic immediately, because if the change in appearance was too outrageous, it might arouse suspicion.

On the day of the prediction test, Kitty and Amelia were visibly shocked.

Over the next few days, Loren began to study the formulation and refinement of various potions. By carefully searching in the knowledge map, he found an elixir that was very useful for early alchemy apprentices.

Alchemists are good at refining potions and building, but not very good at all kinds of combat. Even in combat, they are not good at hand-to-hand combat, either controlling the puppet to attack the opponent, or attacking from a distance, or attacking with poisons, or simply defending.

As far as the plants growing in the reserve are concerned, there are too few poisonous plants, and refining useful poisons cannot collect so many raw materials for the time being, so Loren plans to wait until he has the opportunity to go to the danger zone in the future to collect as many poisons as possible.

In the stage of alchemy apprenticeship, Luo Lun's first task is to improve his defense, and then to improve his combat effectiveness.

If it is in the era of cold weapons, whether it is a sword, gun, arrow, and stick attack, or a fire attack and water attack, he can directly control the cracked plot with his current magic ability, or block the surrounding trees.

But the time of the Mogui Star is different, this is a century of hot weapons, simple earth defense or the use of rocks and trees to form a defensive field, under the attack of an ordinary grenade, everything is gone. Not to mention encountering high-destruction weapons such as kinetic energy bombs.

Loren knew this, so he found a formula called Super Cortical Enhancer in the Knowledge Graph. The efficacy of this agent is divided into five layers, the first layer is skin hardening, which can make the skin close by itself at an emergency moment after absorbing the agent, forming a strong muscle force field to prevent foreign objects from attacking.

The second layer is petrification, which can instantly resist the attack of most bullets. The third layer is metalization, which protects against the onslaught of high-energy weapons and effectively prevents penetrant damage such as sonic weapons.

The fourth layer is alchemy, the skin of the whole body can be refined into an extremely hard outer protective shell, unless it is targeted by a super cutting-edge weapon in the same position several times, otherwise the cortical reinforcement of this state can be called King Kong is not bad.

The fifth layer is called crystallization, and this form of skin is said to be indestructible. Of course, this is at least a defensive realm that can only be achieved by legendary alchemists.

Although the formula of this super cortical enhancer can be mastered, there are many raw materials involved in the formula, many of which Luo Lun has never even heard of, and even some alchemy fonts still need to be transformed with the knowledge he has just gained before he can fully understand them.

It is the raw materials needed for the first layer of cortical enhancer, and Luo Lun only understands half of the literal meaning, he needs to find it on the spot and open the eye-hiding skill before he can know that those are the raw materials he needs.

However, he can't get out yet, and Loren needs to raise himself to the strength that can defend against Level 1 Kinetic Warriors.

I'm afraid that this will make some people in the know drop their jaws, because the combat power of a level 1 kinetic warrior wearing a kinetic suit can already be on par with a junior land tank, and sometimes even slightly higher.

Anyone who knew that Loren wanted to defend himself against an attack by a Level 1 Kinetic Warrior wearing a Kinetic Suit would laugh at him for being insane.

Of course, only Loren knew that this was indeed possible, and all he lacked was careful preparation.

In addition to going to and from class on time every day, he hid in the laboratory, or in order to avoid the suspicion of Walkerman's tutor, Loren would pick out some questions that he didn't know much about to consult Walkerman.

These questions are basically about construction, not about metal materials.

Luo Lun continued to consume and replenish his magic energy every day, and changed the shape of the high-grade metal that could be controlled according to the ideal defensive state, and through secret experiments, it was found that the defense effect was actually quite good.

The results of the predicted assessment are all published by the school, including the scores of each individual score. The total score of the assessment is 400 points, the first item of metal material identification is 100 points, the second item of virtual object construction is 200 points, and the third item of comprehensive knowledge is also 100 points.

Loren scored 100, 191 and 75 respectively, and his overall score was 366, with the high score due to the perfect score for metal materials, and the equally high score for object construction, which was probably deducted because the constructed object was not very satisfactory in terms of structure and appearance.

Charles, a top student, scored 398 points, almost a perfect score. Kotal, on the other hand, had no way of knowing the score because he had been cleared of the assessment results by Tutor Vinsen.

Loren lost the most points in the third category, which also exposed that Loren's basic knowledge, especially in the construction category, was still lacking. To this end, Loren strengthened the investigation and filling of gaps in this area, and ran to Walkman's mentor almost every day to ask for advice, and he was very attentive.

Workman was very pleased with this.

After another seven days, the diligent Loren increased the number of magic units in his body to 7, and he could hit the "Primary Screen Bullet" node.

……

Although the classes of the college are divided according to the three levels of A, B and C, it is only a rough division, which does not mean that all the students in the first class are better than the second class.

There are also students in the class of level C who are better at learning, and after reaching a certain level of credits, they can apply to enter the class of the previous level, or they can choose not to apply. The college did not force this.

And Tarri, who is in the second class on the combat side, is the kind of person who chooses not to apply. As a trainee on the combat side, Tarri's strength has been tested to meet the standard of a Level 1 Kinetic Warrior.

As long as he wishes, he can be eligible to borrow the Academy's kinetic energy suit for training at any time.

When Kitty finds Tarri, he's in the middle of a one-on-ten challenge in the Virtual Battle Arena.

In the huge combat training ground, Tarri's figure moved and moved, moving quickly and explosively. Through the display next to it, you can see the ten enemies that have been virtually built in the field.

Four men had fallen at this moment, but Tarri still had the upper hand, his sturdy figure weaving between the gap between his enemies and his companions, each attack almost fatal.

Soon all ten enemies were down, and Tarri took off his virtual eyepiece and turned to look at the viewing platform, where Kitty smiled sweetly and waved at him with white arms like lotus roots.

"Why are you here?" Tarri jumped onto the stand in a few steps, wiped his sweat, picked up a bottle of pure water and drank it all in one gulp.

"Brother, I want to ask you for a favor." Kitty and Tarri were very casual, pinching the muscles on his arms vigorously, and said exaggeratedly: "Wow, what a thick arm, it's about to catch up with my little waist!" ”

A smile appeared on Tarri's face: "Nothing to do, say, what's the matter?" ”

"Help me protect him." Kitty's big, beautiful eyes blinked.
