Chapter 2

"Thrombus removal progress 9999%, continuing removal..."

"Thrombus removal progress 100%, thrombus removal complete."

After sitting on the train and resting at home for a few days, Guo Tai finally saw the message indicating that the thrombus removal was complete.

"Total removal time: 2784 hours, total thrombus removed: 13569 cubic centimeters, thrombus volume in blood vessels: 0." Immediately after, Guo Tai saw the statistical report.

There were actually about 14 cubic centimeters of thrombus in his body. Fortunately, it was removed; otherwise, it could have caused problems at any time, and Guo Tai would have suffered greatly.

Perhaps due to the excellent treatment effect or a psychological effect, Guo Tai instantly felt refreshed and comfortable.

"Treat coronary heart disease!"

"Insufficient data, unable to implement."

"Treat hypertension!"

"Insufficient data, unable to implement."

"Treat hyperglycemia!"

"Insufficient data, unable to implement."

"Treat hyperlipidemia!"

"Hyperlipidemia is being continuously consumed..."

...

After a series of tests, Guo Tai finally determined what the current nanobots could do.

First, the activity range of the nanobots was limited to blood vessels and muscle tissue; they could not reach other areas.

Second, the functions of the nanobots were very simple. In blood vessels, they could only perform crushing tasks, such as clearing thrombi or breaking up large clumps of lipids.

In muscles, the nanobots could release simulated bioelectricity to precisely control the movement of some muscle fibers.

"How to obtain data?" After receiving too many responses about insufficient data, Guo Tai finally asked.

"Upgrade the control system version." This time, Guo Tai received a clear answer.

Guo Tai immediately remembered that the necessary condition for upgrading the control system was to increase the number of nanobots as soon as possible. The maximum control number was one million.

"Micro-scale titanium powder, I guess I'll have to think of a way at Dad's factory first." Guo Tai pondered, then thought about what reason he could give to go to the factory. After all, it had been several years since Guo Tai last visited his father's factory, and suddenly going there would seem strange.

Fortunately, there was a ready-made reason. Now that Guo Tai was full of illnesses, the first thing he needed to do was to gradually treat his conditions, and losing weight was the top priority.

"Weight loss? If you go to the factory and work for a few days, you'll naturally lose weight." Guo Tai's father, Guo Jianjun, immediately suggested when he heard that his fat son had finally decided to lose weight, without needing Guo Tai to steer the conversation towards the factory.

"Moving around a bit is good." Guo Tai's mother, Ding Yumei, worked in the medical department of the same unit as Guo Jianjun. Although she couldn't treat major illnesses, she was very skilled in basic medical care. Hearing this, she immediately agreed.

Guo Jianjun was a fitter, and Guo Tai had learned the basics of fitter work with his father when he was young. Even during his school's metalworking internship, Guo Tai had excelled.

Actually, the factory where Guo Jianjun worked was not very prosperous and was already in a semi-shutdown state. Using some scrap materials to help Guo Tai lose weight would not draw any attention.

Holding the largest file, Guo Tai began to file the metal block on the vise with great force. After filing for a while, a message suddenly appeared in his mind.

"Record the processing effect?"

The sudden message made Guo Tai pause. What did it mean?

The processing effect, could it be the effect of the file just now? Without responding, Guo Tai thought about it and chose to record.

"Select the file model and hardness."

Following the prompt, Guo Tai answered these questions in his mind.

"Select the workpiece hardness."

Another question followed. The scrap part had a record, so Guo Tai asked Guo Jianjun and immediately got the hardness value.

"Measure the processing effect."

This prompt was probably to record how much was filed off just now. He hadn't measured it just now, but it didn't matter. He could measure it now and record it for the next time.

Cancelling this record, Guo Tai measured the current thickness of the workpiece with a vernier caliper, picked up the file, and filed again, immediately measuring. This time, he got detailed values.

"Processing effect successfully recorded!"

Seeing the message that the record was successful, Guo Tai had a guess and immediately commanded in his mind: "Reproduce the processing effect just now."

Guo Tai was right. As soon as he gave this command, his hands naturally followed the same processing posture, with the same force and angle, and filed again.

While performing the action, Guo Tai clearly understood in his mind that he wasn't moving his arms himself; the nanobots were using bioelectricity to stimulate his arm muscles.

After filing, Guo Tai immediately measured with the vernier caliper, and indeed, the result was exactly the same as before.

Rich! Such a good thing, Guo Tai immediately became excited and started processing with different forces and angles. Each time, he would let the control system record the processing effect and then reproduce it. Then he would switch to workpieces of different hardness and continue the process.

The precision of the vernier caliper was only 0.1 millimeters, which could no longer meet Guo Tai's recording requirements. After recording several hundred times, Guo Tai switched to a micrometer, which had a precision of 10 micrometers (0.01 millimeters), and recorded furiously. Finally, he switched to a dial gauge, which could measure to 1 micrometer (0.001 millimeters).

Guo Jianjun came over to check once, seeing his son sweating and filing, and nodded in satisfaction. He didn't care what he was doing, as long as he was sweating.

"Dad, what is the precision of your manual processing?" Guo Tai took the water Guo Jianjun handed him and asked.

"With enough time, I can finely polish to 0.5 micrometers!" Guo Jianjun replied proudly, "Do you think my fifth-level fitter certification is fake?"

One micrometer is one-hundredth of a millimeter, and 0.5 micrometers is 5 micrometers. This processing precision could already rival some high-precision CNC machines.

"Amazing!" Guo Tai praised Guo Jianjun, extending his thumb, but inwardly he was smiling: "Would I tell you that I can now casually file to a precision of 5 micrometers?"

5 micrometers was already Guo Tai's limit, probably due to the insufficient number of nanobots. But this was enough to satisfy Guo Tai. He had reached Guo Jianjun's level in half a day, so what more could he want?

Of course, this precision could only be achieved with the finest file. As for other skills like drilling, sawing, grinding, and planing, he was far from reaching this level.

However, isn't a fitter known for being able to do anything with a file? First, he would master the file, and then gradually improve other skills. In this aspect, Guo Tai was not in a hurry.

After Guo Tai experimented no less than a thousand times, when he measured again with the dial gauge, another message appeared in his mind.

"Enable the 3D measurement mechanism with both eyes?"
