"Are you sure people can't see it?" Karel wore her upper body, and Lulin crouched behind Karel with a pen dipped in a pigment similar to the color of her skin.

"Of course, I learned 3D painting, and the results are absolutely good." Putting down the brush in her hand, Lu Lin shook her sore arm. "Okay, that's pretty much it, just wait for the paint to dry."

Hearing Lulin's words, Karel stretched out his arm in front of his eyes and looked at it, the original black-red scales disappeared, replaced by a layer of white skin, of course, it can only look fair, if you touch it with your hands, you can still feel the feeling of the cuticle of the scales.

Fortunately, the scales on the body are very thin, almost the same as the skin, so the 3D drawing method is used to solve the light and shadow anomalies in the gaps between the scales, and it is difficult to detect the abnormalities on the skin.

"This pigment is specially used for camouflage in the assassin tutorial, it can be used for 4 months without fading, and you can take a bath and wash your face, provided that you don't have nothing to do and scrape with a knife." Lu Lin pinched Karel's arm, then looked at her fingers, which were not stained with paint, and said with satisfaction.

"When did you get the illusion that I would scratch myself with a knife when I was bored?" For Lu Lin's strange words, Karel complained unceremoniously.

Since returning from the misty swamp, the scales on his face have caused a lot of trouble to Karel, if only he has it on his body, he can't see it if he covers it with clothes, the key is the big scale on his face, he can't still wear a mask when eating, so much disharmony, after a day of nibbling on truffle soufflés in the dormitory, Lu Lin suddenly sent a message, saying that he had found a way to solve the scales on Karel's body, and asked him to come to his dormitory.

Relying on stealth, Karel climbed directly over the wall from the periphery of the dormitory building, climbed a distance as far as half a school, and finally climbed into Lulin's dormitory, but he didn't expect that this so-called solution was the ancient disguise.

In fact, disguise should be a compulsory subject for assassins, but after the invention of the method of infinite time stealth, the usefulness of disguise gradually decreased, and with the development of the shapeshifting skill, the ancient skill of disguise was completely swept into the dustbin of history, however, now it has been turned out by Lu Lin, and it still looks quite useful.

"By the way, Lulin, what's your reward?" Getting dressed, Karel asked suddenly.

"Rewards? Just going to the Misty Swamp? ”

Karel nodded.

"A magic fruit, a 2% probability, a lot of engineering drawings, a set of shaman suits, ugly to death." Lu Lin pulled a box out from under the chuang and kicked it open, revealing a set of chain mail with the beast's face decoration, glowing with a faint blue light.

For students who participate in the training, the college can't say that it doesn't give out some rewards, it's all a life-saving experience, and if there is no appropriate reward, who will pay attention to you next time?

These rewards are generally some skills or recipes that fit your own class, like Karel and Lulin, who are alchemy and engineering, respectively, so they are randomly given some recipes that may be used, as well as some sets or something.

As for the magic fruit, this kind of thing is very common, there is a kind of magic tree, this kind of tree grows in places rich in elements, such as volcanic areas, polar regions, or near various magic ore veins, formed by mutation, its branches are the best material for making staffs, and the leaves are the best materials for making magic potions, then the fruit of this thing is the magic fruit, because of its small probability of strengthening the effect of skills, also known as skill strengthening fruits.

The effect of this skill enhancement fruit is more pitiful, and there are two effects on the enhancement of skills, one is the temporary enhancement of the 95%-99% probability, the time is as long as one hour, and the strengthening range can reach 30%, for example, Karel is now a five-star piercing blow, which can crack the black dragon's head, and after eating this fruit, he can directly pierce the black dragon's head; The second effect is permanent enhancement, 5%-1% probability, but only 10% effect at most, this thing is generally a rich tyrant to buy a lot of home to eat, with the number of probabilities, and it is also a reward for pit people who are commonly used by various schools.

"I'm just like you, I also have a magic fruit and a few alchemy recipes, but I don't have professional equipment, so they gave me a skill book to reduce my skill CD." Karel pulled out a parchment-bound skill book and shook it in front of Lulin's eyes.

"Damn, this is good." Lu Lin snatched the skill book, "This girl wants it, don't you mind." ”

"Feel free, what's mine is yours." Karel shrugged his shoulders and motioned for Lulene not to be polite.

"Well, you're so nice~" Lulin said coquettishly, kissed Karel, and then went to bed and began to look through the skill book.

This skill book is written on a special parchment using the power of the soul, as long as you look at it intently, you can absorb the power of the soul and obtain the ability to write, but because this way of writing is too difficult to master, the production is not large, and it has always been very rare. However, for a stalker like Karel, whose skills are all short or non-CD, the attraction is not great.

Watching Lu Lin begin to absorb the soul power from the skill book, a bored Karel flipped through the small stack of engineering drawings that Lu Lin had placed casually on the table.

The world of engineering is very developed, almost one of the pillars of the current civilization, and it is almost 100% in line with the engineering that Karel inherited from his game character, that is, Karel has practiced top-level engineering in the game, and it is also top-level in this world.

"Hmm, let me see, the super improved version of the Spell Energy Goggles, it's useless... Dense explosives, toys for the little ones ... Remote mailbox, this is kind of interesting, but I've learned it... Energy converter, hey, this is good... Super horsepower rocket engine, I'll go, this awesome! ”

Looking at a few drawings on Lu Lin's desk, I didn't expect to find a lot of good goods, and at the same time, I also found out how intentional the teachers of this school are. Do you give these high-powered drawings to a novice who has only been studying engineering for a few months to encourage them to blow up the school?

Taking out a pen and paper, Karel completely copied the recipe for the energy converter and the super-horsepower rocket engine, anyway, this kind of thing is used to reward students, and there are no restrictions on its use, right?

The Energy Converter, which is something similar to the Universal Charge, can convert any energy into any other energy, such as converting Shadow into Holy Light, Fire into Ice, and Elemental into Electricity, although there will be some loss, but it is still within the acceptable range.

The ultra-high-horsepower rocket engine, this thing looks similar to the liquid hydrogen engine before the crossing, using liquid Austrian energy as an energy source, just enough to be used with an energy converter, the effect is twice great!

Looking at these two engineering products, a bold idea came to Carrel's mind, and it lingered, and a hideous smile appeared on the corner of his mouth.

"What are you looking at? Laughing so lewdly. After learning the skill book, Lu Lin lay on Karel's back with a hint of coquettishness, and the soft touch made Karel's heart flutter for a while.

"Wasn't it very tiring to fight when I encountered the Thorny Beast in the Misty Swamp before, so I want to make some auxiliary weapons." Squeezing Lulene's leg, Karel said.

"That's all? Can these things make weapons? Looking at the two pictures in front of her, the energy converter and the engine, Lu Lin couldn't associate it with weapons, after all, this is the difference between the thinking of men and women, and it is not so easy to make up.

"Yes, that's the main thing." After drawing the last picture, Karel turned around and hugged Lulin in his arms, "Baby, is that engineering teacher of yours in charge of running the lab?" ”

"Hmm, it seems like yes, what, you want to apply for a research room?" Nestled in Carrel's arms like a hamster, Lulin said.

"Yes, some things are not so easy to make."

"Okay, come to class with me tomorrow, and then go to the application laboratory."

"Okay!"
