Lin Zhiyue is well aware that many difficulties need to be overcome to realize this function.

She once again rummaged through the mountain of materials and found all kinds of microelectronic components, including tiny and precise chips, wires as thin as hair, and sensor chips as thin as a cicada's wing.

These components gleam with tiny rays of light under the soft halo, as if waiting to be given a new mission.

She sat at the workbench in the space, her eyes focused and determined.

Then she picked up the tweezers, picked up the tiny chip, aligned it with the solder joint on the circuit board, and with the help of a magnifying glass, carefully performed the soldering.

The chip is as small as a grain of sand, and the solder joints are so fine that they are almost imperceptible. If you are not careful, the entire chip may be scrapped.

Lin Zhiyue held his breath, beads of sweat appeared on his forehead, but his arms were as steady as a rock, and he accurately fixed the chip on the circuit board.

Next, it’s time to connect the wires.

These wires are as thin as gossamer threads, and Lin Zhiyue must connect them one by one to the chips, sensors and the main control circuit of the electric vehicle.

Her fingers moved nimbly among these tiny components, her eyes fixed on the operating area, as if the whole world was left with only her and the transformation work in her hands.

After several hours of effort, the wire connections were completed, but when she turned on the power to test, the fingerprint verification system did not respond.

Lin Zhiyue was not discouraged. She calmed down and carefully checked every circuit and every soldering point.

After repeated inspections, she found that there was a loose connection at a solder joint, which caused the current to be unable to be transmitted normally.

She picked up the soldering iron again and repaired the loose joints.

After testing again, the system made a "beep" sound and the words "Waiting for fingerprint entry" were displayed on the screen.

Lin Zhiyue excitedly pressed his finger on the sensor and recorded his fingerprint.

Afterwards, she tried pressing again at different angles and with different strengths, and the system was able to recognize it quickly and accurately.

Mission accomplished! Lin Zhiyue breathed a sigh of relief, looking at the prototype of the solar electric car that had been integrated with the fingerprint verification system, with a full sense of accomplishment on his face.
