Before he set off, Ma Lu followed his usual routine and calculated his profit for the week.
Thanks to the upgrade of the Collection Bag, he had managed to bring back an extra 100 kilograms of ingredients. Selling 7,775 portions of Queen's Crisps at 18 yuan each, his total revenue came to 139,950.
The costs had risen compared to last week, mainly because Old Wang's newly adjusted sauce included several fresh vegetables, and they also switched out the gas cylinder and bought four barrels of oil, costing a total of 2,189.7.
Therefore, his profit amounted to 137,760.3.
The first thing Ma Lu did after this money entered his account was to continue upgrading the Collection Bag.
He spent 80,000 yuan to upgrade the Collection Bag from Level 4 to Level 5, increasing the storage limit to 800 kilograms. As for advancing further to Level 6, he would need 160,000 yuan, which he didn't have at hand.
Then Ma Lu added 20,000 yuan to his electric account and placed an order for a humidifier.
