The next day.
Chen Yu had not slept all night.
At last, following the instructions in the Poison Scripture, he had successfully refined a poison that could affect Golden Core cultivators: No. 88 Poison.
This poison was rather unusual.
Once ingested, it made the body curl up uncontrollably.
Its effects could last a quarter of an hour.
"I finally did it!" Chen Yu looked at the gray powder in the transparent container in his hand, his face lighting up with delight.
The usual routine.
Whenever he refined a new poison, he let his old friend have the first taste.
Holding the No. 88 Poison, Chen Yu poured some through the gap in the coffin beside him. Whether it worked was secondary; he had simply made a habit of this routine.
But this time, after Chen Yu poured the No. 88 Poison through the gap in the coffin...
Almost immediately, a sudden thump came from inside, startling Chen Yu. There was only that single sound, however, before silence fell again.
Did the No. 88 Poison take effect?
Could that sound have been the person inside hitting the coffin as his body curled up?
Chen Yu was astonished.
Previously, he had tried putting all sorts of things into the coffin. Besides poison, he had tried flooding it with water and burning it with fire, but no matter what he tried, not a sound had ever come from inside.
Since it also blocked Divine Sense, Chen Yu had once believed the coffin was completely sealed.
But what had just happened proved that it was not.
*In other words, if I can make a poison capable of killing a Golden Core cultivator and pour it inside, I can deal with this problem directly. There's no need to wait until I reach the Golden Core
