Although the medical methods in the future world are highly developed, the resources for treatment are still quite scarce. Aside from losing his memory, Nguyễn Đường had no other major issues. The muscle shrinkage caused by the long period of inactivity wasn’t a big problem either; he could easily recover by resting at home.
Therefore, after Nguyễn Đường woke up, he only stayed in the hospital for a few days before being discharged.
Fortunately, the transportation system in the future world is very convenient. Flying cars connect all directions, and all you need to do is use the optical brain to call a car. The optical brain is a light-based computer, compact, portable, and fully functional. Nguyễn Đường’s optical brain was in the form of a bracelet, looking like an updated version of a fitness tracker, sleek in design, and had the cold metallic feel.
He summoned a car via his optical brain, and five minutes later, a flying car arrived precisely at his location, thanks to the GPS system. The car had no driver and flew at high speed, but it was very smooth and comfortable, making the ride both safe and convenient.
Fifteen minutes later, Nguyễn Đường was standing 25 floors above ground, holding onto the railing, feeling slightly shaky.
In the future world, there are no staircases or elevators; windows have become large doors, and there is a landing pad outside the door for flying cars to park. If you want to descend to the ground, you can use the landing pad to fly down, which is both safe and convenient.
Nguyễn Đường, who had a mild fear of heights, made a conscious effort not to look down. He pressed his finger on the fingerprint recognition system, and the door to his apartment opened automatically.
As Nguyễn Đường entered the house, he saw a robot, almost as tall as him, standing outside the door wearing indoor slippers. "Master, welcome home."
Yesterday, Nguyễn Đường had heard Thôi Lỗi mention that when he signed the contract with the company, they had equipped him with an ultra-intelligent housekeeping robot. The robot could clean, cook, give massages, do work, and had many other skills. Even though he had canceled the contract with the company, the robot had been transferred to him. After all, since he had just been discharged from the hospital, he needed an intelligent housekeeper to take care of him.
He couldn't help but feel grateful; it was truly a company with a lot of heart. He decided that if he ever had the chance, he would repay them.
"Thank you, Xiao Bai." Nguyễn Đường changed into the slippers brought by the robot. He remembered that Thôi Lỗi had said the original owner of the robot had called it Xiao Bai.
"No need to thank me. Would you like to eat now, Master?"
Hearing this, Nguyễn Đường touched his stomach and indeed felt a little hungry. He nodded. "Yes."
Xiao Bai quickly brought out the nutritional drink for him.
When Nguyễn Đường saw the drink, he frowned slightly. During his time in the hospital, he had to drink this. It was a small test tube-like bottle containing sugar, albumin, and trace elements necessary for the body. It was convenient and minimized the effort, but the downside was that it had no taste, even though it filled the stomach. The desire for actual food remained unfulfilled. For someone like Nguyễn Đường, who had grown up with a love for fine cuisine, this was even more frustrating than hunger.
"Do you have anything else to eat?" He really didn’t want to drink the nutritional drink anymore.
A blue light flickered in Xiao Bai’s electronic eyes. After a moment, it said, "According to the hospital's medical records, your body is still in a recovery phase, and it is recommended that you consume liquid food. There are no food reserves in the house, only nutritional drinks that meet the requirements. You can purchase ingredients online or order food."
Nguyễn Đường thought for a moment and nodded. It made sense; he had been in a coma for five years, so there were no cooking ingredients at home. Even though Xiao Bai was an intelligent housekeeper, it couldn't use the master’s finances without permission.
He opened his optical brain, and the projection of the interstellar web appeared before him. The homepage of the web looked similar to a search page on Earth, with a search bar at the top and popular search categories below: mechs, shopping, television, livestreams, games, star battles, and more.
Nguyễn Đường clicked on the shopping category, and the page quickly switched to the shopping section. Given his current physical condition, he could only have liquid food, so he decided to order a bowl of salted egg and pork porridge. However, when he searched for salted eggs, there were no results.
He backed out to the food section and found that the available cooking ingredients were quite limited. There were only two categories: meat and vegetables, with just one or two pages of ingredients in each. The meat section had a bit more variety, including fish, but there were only about twenty types. Vegetables were all jumbled together with fruits and grains, about thirty or forty types, and all of them were regenerated ingredients, with no artificial products available.
Each food item had a green "Safety" label, and Nguyễn Đường, curious, read up on the information about the cooking ingredients. He learned that thousands of years ago, when humanity fled Earth, they had carried seeds and livestock with them, similar to the Noah's Ark story from the Bible. After stabilizing, they were attacked by aliens. A long war ensued, lasting thousands of years, with everyone becoming soldiers, leaving no time to focus on food. After discovering nutritional drinks, they became the sole food source for everyone.
It wasn’t until the war ended that the scientific institute used genetic technology to regenerate the livestock and seeds, which had been stored in underground refrigerators. Since the environment in space was different from Earth, to avoid mutation of the food ingredients, the empire's scientific institute tested the regenerated food to ensure its safety before it was released to the public.
Now, Nguyễn Đường saw that all seventy-four cooking ingredients were certified by the scientific institute, but since he couldn't find salted eggs, it meant they hadn't been regenerated or certified yet. It seemed like he would have to wait a while longer.
