The addition of a hundred alchemy cauldrons had greatly increased Lu Ming's speed of refining pills.
For the next ten days, Lu Ming refined pills day and night.
After more than ten days of refining pills, Lu Ming could roughly estimate that he could produce pills in a year.
In a year, he would be able to refine about 200 million desolate pills.
It was still not enough!
200 million a year, 20 years would be 4 billion. It was still far from the 12 billion he wanted.
He could only take it one step at a time.
In the blink of an eye, another five days passed.
"They're here!"
Lu Ming muttered, his eyes looking into the distance.
In the distance, a rainbow flickered as figures flew over.
They were all from the heavenly human tribe, and there were thousands of them.
