The Meltdown Count [Weekly Short-Short Note Hidden Theme] (409 characters)

The prototype of a giant robot weapon, built with the full might of Country A, was finally completed.
The development code was "Count".
Equipped with a nuclear reactor boasting an output of 750MW as its main power source, and armed with missiles, lasers, and large-caliber cannons, it was truly an invincible super robot capable of close-quarters combat as well.

"Now, we will conduct the activation test."
The chief engineer gave the order to start the activation test.
The reactor was ignited.
However, an anomaly occurred.
"It's an emergency! The main power source is running wild; at this rate, a meltdown will occur!"
"Inject concrete immediately!"
By a hair's breadth, a nuclear explosion did not occur.
However, the Count was encased in concrete.

Yet, the flame of the engineers' fighting spirit had not been extinguished.
Failure is experience.
The great inventor Thomas Edison also said, "I have not failed. I've just found 10,000 ways that won't work."
Development of the next prototype began immediately.

The development code is Marquis.
