Having found out that the beast was at the Shell genesis stage, Lin Wu knew exactly what to expect now and had an estimate of how much power he would need to use.
Lin Wu soon came up with a strategy that he had not used before.
"Time to test out my abilities finally…" Lin Wu said as he paced Tim down.
The underground area was already expanded by him enough that he could coil up there. Tim was already asleep, thus Lin Wu could just leave him here while he fought the beast up on the surface.
Lin Wu made some points on the map about how he wanted things to go and began his work.
Lin Wu first dug out a circular radius around the nest of the Four Winged Guna griffins. The diameter of the circle was almost a kilometer, and it was about a hundred meters deep since Lin Wu knew he would alert the beasts on the surface due to the vibrations.
While the Nascent soul realm ones might not have spirit sense good enough to detect him deep inside, the Dao Shell realm one definitely would be able to do that. The last thing Lin Wu wanted was for them to just run away when he wanted them dead.
Even though Lin Wu was fast, he was still not fast enough to catch up with a beast that was born for flying. Even if he might catch up underground, the Four Winged Guna Griffin would be high up in the sky and Lin Wu's speed would slow down if he flew in the air.
Thus he needed to prevent them from ever flying away and either tie them down or kill them before that.
'Now to make the channels…' Lin Wu thought as he extended his tail to the top while narrowing it down as much as possible.
In the end, a thin rod that was barely two centimeters wide poked out of the surface. It was a small enough change that the beasts did not notice it and neither did it cause any noise.
~phew~
"They are busy with themselves. This should make it a bit easier." Lin Wu muttered.
He then repeated the same procedure several more times until hundreds of such holes were made along the circumference of the circle that Lin Wu had dug out.
"Alright, part one done." Lin Wu said as he prepared for the next part.
~HOO~
He took a deep breath before letting out a black gas from his mouth.
~WHOOSH~
The black gas started to spread in the circular area he had dug out and rose to the top. Lin Wu continued spewing out the black gas until half of the volume of the tunnels was filled with it.
He had already blocked the tunnel that went towards Tim so he would not be affected.
Once this was done, Lin Wu checked the map one last time before digging towards the center of the circle. This was where the nest of the Four Winged Guna griffins was, and they were currently asleep.
It was night time and it looked like they had fed just a few hours ago thus they were contently sleeping. Still, Lin Wu could tell that one of the Griffins was alert despite having its eyes closed.
It was one of the Nascent soul realm and thus Lin Wu didn't mind it as much and knew that he would be able to hide from it for the most part.
"Now comes the more difficult part…" Lin Wu muttered as he created a small channel all the way to the top.
~tremble~
The Four Winged Guna griffin that was not fully asleep squinted its eyes and shook its head before opening its eyes. It looked around but did not see anything.
~tremble~
But a few seconds later, it could feel something again and it checked the area again feeling confused.
~tremble~
Finally, it could feel the vibrations from underground and became alert. It looked towards the source of it, finding them to be rather weak tremors. It was the same as some animal or beast walking around.
The Four Winged Guna griffins were the overlords of the Guna plains and had no predators thus, they were fearless. To them, if a beast came this close to them, it was either out of a mistake or it was just passing by.
Still, it was an offense they would not take if it was a human instead of a beast.
But soon it became even more confused as he saw a very small portion of the soil move.
"Ek?" It tilted its head in concussion and stood up.
The other griffins were still sleeping and didn't mind this much movement. Unless the beast specially alerted them and called out, they will not respond.
It stepped towards the area where the soil was moving and looked at it closely.
~tremble~
The soil finally parted and a small object protruded from the soil. But as soon as it appeared, it disappeared back down.
"Eh?" The beast was even more confused and wondered what it was.
It used its spirit sense and probed the ground trying to sense of it was some ground beast that had wandered. But the moment it did that, its instincts alarmed it.
~shua~
A faint yellow gas rose from below the beast's head and was quickly inhaled by it.
~huu~
The beast took a deer breath, wanting to let out a loud cry, but this only made it inhale more of the gas. Just as it had gathered enough power to cry out, it felt a weakness spreading all over its body.
"Viii…" A low sound escaped its beak before it collapsed back on the ground.
~thud~
"EK!!!" the other Four Winged Guna Griffins felt the strange sound and woke up.
They saw their kin seemingly sleeping on the ground some distance away from them.
"Ke?" Two of them went to check up on it and nudged it.
~thud~ thud~
But just a couple of seconds later, they too fell to the ground.
