"Wait a moment."

Just as Zhou Huai'an was about to utter the word "end," a clear and calm voice resounded throughout the entire square.

Everyone looked in the direction of the sound.

Just when everyone thought the situation was hopeless, Su Tang calmly walked onto the platform.

She didn't look at anyone, but went straight to the stove that was emitting black smoke.

She first leaned down slightly, gently sniffed the cigarette butt, and raised her eyebrows almost imperceptibly.

Then, she stretched out her fair fingers, picked up a little black coal ash from the furnace opening, and gently rubbed it between her fingertips.

Her mind instantly became crystal clear.

This smell wasn't just pure coal smoke; it carried a damp, earthy odor.

The texture of this coal ash is also wrong; it's sticky and has something mixed in.

Good heavens, Huai'an's methods this week are so low-level, he's directly tampering with the coal.

She turned around, her gaze sweeping over everyone else, landing directly on Zhou Huai'an's hypocritical face, and said loudly:

"Political Commissar Zhou, don't be so quick to draw conclusions."

The entire room fell silent instantly.

"Our furnace is fine, the problem is with the coal."

Zhou Huai'an's pupils suddenly contracted.

Before he could react, Su Tang had already strode over to the expert team's furnace. To everyone's astonishment, she grabbed a handful of shiny black, high-quality anthracite coal from their coal basket, turned around, walked back to her own furnace, and threw it all in with a "whoosh."

Then, she took out a small medical glass bottle containing a transparent gel-like substance from the pocket of her work clothes.

She unscrewed the lid and gently squeezed a little bit of kindling into the stove.

Before anyone could even see what it was, she struck a match and threw it in.

"boom!"

A soft rumble was heard!

A pale blue, pure flame instantly rose up! Inside the furnace, the high-quality smokeless coal was quickly ignited, and the flames changed from blue to a bright orange-red, suddenly becoming vigorous and stable, without emitting a single wisp of black smoke!

A scorching warmth began to spread outwards.

Everyone was stunned by the incredible skill displayed before them.

Meanwhile, in the center of the square, the pointers of two thermometers borrowed from the research institute began to slowly jump.

The behemoth that was manned by the expert team, though blazing with fire and radiating intense heat, consumed an astonishing amount of coal, forcing a worker to frequently add coal into it. The pointer on the pyrometer beside it climbed slowly and reluctantly.

Meanwhile, on Su Tang's side, the small black stove was burning quietly and steadily. There was no thick smoke, no loud popping sounds, only a steady and comfortable flow of heat spreading outwards.

Ten minutes later, a miracle happened.

The thermometer belonging to Su Tang's group seemed to be injected with infinite power, its pointer soaring upwards, surpassing 40, 50, 60... and finally stopping steadily at an astonishing mark that no one could believe!
