In order to effectively reduce everyone's burden, Jia Lan tried his best to design and manufacture various practical tools for them during his waking hours every day, aiming to greatly reduce their work pressure.

These tools include but are not limited to "push-bar canning machine", "link-bar mixer", and "wheel-type leather conveyor belt".

These seemingly simple tools are actually the products of Jia Lan's sudden inspiration.

Although they only use simple wooden structures and lever transmission methods, they miraculously reduce everyone's work pressure.

Take the "push-bar canning machine" for example, which is a huge wooden pump barrel with a round wooden board covered with ointment cleverly installed inside.

By applying pressure through the lever, every time people pull the handle on the barrel, they can accurately squeeze out the ointment from the twenty wooden nozzles under the pump barrel and quickly pour it into a plate of twenty small pottery jars on a wooden tray.

Then, just by shaking the wheel of the "wheel-type leather conveyor belt" once, the wooden tray placed on the conveyor belt made of leather can be sent to the bottom of the pump barrel for the next round of canning.

In this way, the work of the Brown family and Alan became much easier. They only needed to cover the small pottery jars on the wooden tray and put them neatly into the wooden box one by one.

However, this also caused a new problem: the ointment provided by Aunt Brown was seriously insufficient. Most of the time, Old Brown and his friends were idly waiting for Aunt Brown's ointment to be boiled.

This made Aunt Brown, who had just enjoyed the authority for a few days, very unhappy. She begged Jia Lan to design a tool for her to speed up the work progress.

In order to meet Aunt Brown's requirements, Jia Lan took great pains and finally designed a stirring device composed of a complex mechanism and equipped with ten stirrers - a "link stirrer".

In this way, Aunt Brown only needs to shake a rope-driven wheel on the device to make ten stirrers rotate at the same time, greatly speeding up the boiling speed of the ointment.

Aunt Brown was very happy, and she happily asked Jia Lan to add a larger potion crucible for her. In this way, she can boil more ointment at one time.

In the end, even the work of shaking the wheel was handed over to poor old Brown by Aunt Brown. And she herself only needs to leisurely watch the fire.

Just these simple tool improvements have increased the output of the small family-run potion workshop "Lemli Potion Workshop" several times at once.

Ten hot stoves almost filled the entire yard, and the high temperature they emitted almost scorched the wooden hut in the yard. The originally damp ground has now become extremely dry and even cracked.

It is not summer yet, but Old Lyme has been shirtless early, drinking cold water desperately like a tired old dog, trying to relieve the discomfort caused by the heat.

Aunt Brown, wearing a linen waistcoat that showed off her plump white arms, patrolled around the hot stoves.

Then, she would scoop a spoonful of cool water from the small pool in the yard and pour it over her head, instantly becoming refreshed and patrolling her territory again with full energy.

Ten specially made oversized potion crucibles, each of which can hold 25 kilograms of ointment, can produce an amazing 2,500 bottles of micro-violet ointment per hour.

Six batches are produced a day, totaling 15,000 bottles of ointment. Such amazing productivity is enough to shock any pharmacist.

Old dwarf Justin, who once ran a pottery shop, has now completely transformed. He closed his pottery shop, sent four of his men to help in the courtyard, and personally stayed in the pottery workshop, urging them to rush to burn small pottery bottles for ointment.

This deal is undoubtedly a big business, requiring 15,000 small pottery bottles every day. Although the unit price of each pottery bottle has dropped from one copper Danding to five copper Dandings, there is still a transaction volume of 30 gold Talans a day. Such income is unimaginable for any pottery shop.

Old Justin knows this very well, and now he only hopes that this deal can be maintained for a long time. Although 20 of the 30 gold talans earned every day had to be paid to more than a dozen pottery workshops, and the rest had to be used to order thin wooden boxes from the wood shop and pay the freight of the carriage shop, the income of no less than 10 gold talans a day had made him and his four partners give up the pottery shop and join the Lemley Pharmacy Workshop as the purchasing and sales supervisor after signing a contract.

The Lemley Pharmacy Workshop has undergone earth-shaking changes in just seven days. Although the production of medicine is still carried out in the original small courtyard, the courtyards of several neighbors around have been rented by Aunt Brown as warehouses. In these courtyards, the piled-up wooden boxes of medicines with 100 bottles per box have almost been stacked beyond the courtyard wall.

In order to cope with this rapidly expanding production scale, Aunt Brown also hired neighbors around and signed confidentiality agreements with them to let them serve as workers in various processes, such as porters.

Such measures not only solved the problem of labor shortage, but also made the production process of the entire pharmacy workshop smoother.

Jia Lan, the founder of Lemley's potion workshop, basically no longer manages the affairs of the workshop. In addition to the sixteen hours of sleep every day, he spends most of the remaining eight hours in meditation.

In seven days, the changes in the Brown family courtyard made him realize that this change was actually due to his "sudden ideas" and "creativity".

With the recovery of mental strength after a long sleep, Jia Lan began to be able to meditate and gradually shortened his sleep time.

While meditating, he also began to learn and master the huge knowledge system left to him by the foreign "friend".

Although Jia Lan did not know whether the knowledge system left by the foreign soul was a deliberate "conspiracy" or a simple "gift" of goodwill, he found that his behavior had been unconsciously affected by the foreign soul and began to undergo some unpredictable changes.

This change made him feel both surprised and full of expectations, because he knew that this would be a major turning point in his life.
