Yu Anbang helped tend the algae for an hour before hurriedly leaving.
Song He continued fighting alone, replenishing the nutrients in each culture flask while repeatedly observing them under a microscope.
By three in the afternoon, dozens of culture flasks had turned green. The murky green looked like imprisoned fog, drifting aimlessly inside the bottles.
At last, the Black Technology Blueprint appeared!
The progress bar advanced to 10%. There was now enough algae in the laboratory, and the algae in most of the culture flasks weighed nearly a kilogram. The first step, "Find Algae," was complete!
Song He examined the blueprint's next step. It took up a full 30% of the progress bar.
Artificial Organelle: Implant suitable artificial organelles into the algae, granting them the properties of nitrifying bacteria. They would be able to oxidize ammonia into nitrite, then oxidize nitrite into nitrate, thereby increasing their own energy intake.
"Thank goodness!" Cold sweat poured down Song He's forehead.
He turned to look at the corner of the laboratory. A piano-sized instrument lay there in silence: the Organelle All-in-One Machine.
The machine was outrageously expensive, with a retail price of forty million. Even the discounted secondhand model was worth twenty-eight million. On top of that, the materials for each startup cost at least ten thousand. He had set aside three million for materials, which had eaten up a huge chunk of his research funding!
He had once considered going without the machine. After all, artificial organelles were a niche field, and if it proved useless, the machine would become nothing more than an extravagant ornament. But after hesitating, he had gritted his teeth and ordered it anyway.
That had been close! Fortunately, he had bought it. Otherwise, he would never have cleared this stage!
Song He got to work, selecting a
