Oil Press.

The village didn't lack food or warm clothes thanks to three hunters and his linen. Aron started slowly drew blueprints for instruments and interesting tools from the modern world. 

'I instructed people to take care of their hygiene… water doesn't kill bacteria on their hands…' He needed to recreate a soap.

'Soap…' The simplest soap was a combination of lye and oil with possible additions. Aron cooked with usage of lard from animals, he didn't want use entire oil on this because animals' growth was slower than plant's growth. There were many plants with possibility of oil extraction, so he decided to build oil press.

Aron needed to build blast furnace to process iron into steel, he decided to postpone it to late autumn. Oil press could be built with simple iron or copper, and he could simply smelt it and built a better version later in future.

'Oil press…making a lye…i won't achieve hard soap right now…'His current capabilities could create lye solution with of potassium hydroxide lye, for hard soaps sodium hydroxide lye was better. 

'I need electricity. First things…are first. Let's go with liquid soap and slowly build a blast furnace.' Aron couldn't build those things in a middle of nowhere. Steel will be his trump card and letting someone stole would be at least stupid. 

'I am weak. When you are barely protecting your own life…you cannot protect your wealth and dignity.' It was simple line of thought, this world had things beyond his comprehension. There are many monsters and superintelligent creatures. Martial artists or mages, he couldn't hold a candle for any of them yet.

His oil press was simple meat mincer, he added some holes to let oil drip into a collector with a filter. The use was simple, so he could introduce this work for few villagers.

It took him some time to put this tool together in fully functioning machine, he took out the flax seeds and started extraction process. 

Flaxseed oil will be great for soap making, and some simple cooking uses. The trail was successful, so he decided to a built couple of those in workshop area. 

He decides to use one of the rooms in his mansion for this process, and ordered another construction inside of a village.

'There is more 'factories' in this village. I don't need to care about this anyway. This area will be rebuilt in future…' The four villages needed to fuse into one city, many buildings needed to be upgraded to brick or stone. The change will be slow and he couldn't leave settlers without roof above their heads.

The next thing was lye making, and it was pretty simple thing. He needed a big wooden barrel filled with three layers. First two layers were created from stones and straw, while the rest of the container was filled with ashes from hard wood. The entire process will need holes on a bottom to let lye water come out and fell into glass container. The potassium hydroxide is caustic and corrosive, so he needed to be careful. The final ingredient was rain water, ashes needed to be wet. He needed to test personally how much water was needed for this process to instruct people later.

Another thing, he needed was distilled water. The distillation will be good for his another project, he wanted to recreate some of the alcohols from Earth. 

The process of making of liquid soap wasn't hard after getting all ingredients. The first step was to boil oil for four hours with high heat. His second step was to add lye mixed in distilled water, stirring it up to fuse it into mixture. The heat needed to be suppressed to low and boil like this for another six hours. The mixture will become clear and its consistency will be similar to thick honey. It was time to pour more distilled water to dissolve the mixture. The last step is pouring dissolved mixture into water jugs and letting it age for four weeks. 

The right recipe needed experimentation as every oil reacted differently with lye. He created few trial mixtures and left them in workshop area. Few hours outside will be days inside of space, so he could find the right recipe in no time. 

His archer profession reached maximum level and he got 3 possible paths to advance. The first option was becoming Great Archer, it was more advanced version of an archer without many interesting features.

Second option was Long Bow Archer, it could be considered as specialization for long distance shooting. It was like a modern-day sniper among the medium range archers, and Aron didn't need to shoot further than 100 meters. 

Third and most tempting option was Ranger, it was like spec ops of archer division. Mobile killing with skill to fight in close quarters and rotate on a battlefield if needed. Fast and accurate, it was perfect advancement for Aron. He was fighting on both close and long distance.

'Let's go with ranger! It has techniques made for me.' His fighting needed to be adaptive and a ranger was best solution. His target was to gain proficiency in multiple professions at the same time. 

[Skill Ranger's footwork generated]

[Skill Adaptive Fighting]

[Adaptive Fighting]

[Desc: User adapts to a current environment. For example if he cannot change a weapon, he uses a current weapon in melee combat.]

This skill was pretty useful in case of inability to summon other weapon, and he could fight with bow as weapon or anything in surroundings. It sounded simple, but using things and using them proficiently was two different things.

'I got Battle instinct from a quest.' It was one of greatest things, and he got from quest. Having good battle instinct made his battle way easier, it was a subconscious booster of his accuracy and decision making. 

'If I met Robert now. He would be dead meat in seconds.' His overall strength increased and what's more important his skill with weapons was getting better every day. Aron was using a random weapon during their battle, and he wasn't proficient with it. The battle would go differently if he was skilled in any of used weapons. 

Battles in simulations allowed him to see all his shortcomings, and the most interesting battles were actually with himself. The easiest way to spot flaw in your fighting style was to fight someone with exact the same style.

Aron left space and sat on chair in deep thoughts, and he needed to visit city soon. Anything he will get in city will later become his own product with space powers. 

BANG! BANG! Someone was pounding at his doors with great strength. Aron opened door and saw Rirak with worried expression.

Rirak was a strong warrior, so a problem was serious as he came to Aron.
