William moved directly towards the top of the hill. The first thing he did was to clear a spot of any plant at the centre of that top using his rusty sword. After doing so for half an hour, he finally cleared enough space for his next step.
Without hesitation he injured his left hand and let the blood drop over his fingers. Then he started to write some letters belonging to a weird language, encircling the area he just cleared, using his blood.
These letters looked a bit weird, and anyone looking at him right now would suspect they even meant anything. But William knew the meaning of these letters. He was laying down some sort of protective spell surrounding the central region.
"Done," after finished, he didn't wrap his wound and instead went towards the sloping side of the hill.
He wasn't worried for his blood to attract those monkeys. After all, he wanted them to come. As he reached the edge of the twenty metres tall hill, he took out one red leafed flower, squeezed it with his bloodied hand and let the blood mix with its fragrance and fall on the ground.
It was unknown to people of this world the magical features of this flower. If mixed with blood, it could turn into a ticking bomb, enough to cause a small explosion.
Of course, the stronger the blood owner was, the stronger the explosion became. But even with his current weak condition, he was sure the explosion this flower would create was enough to kill a couple of monkeys at least.
He had fifty flowers in his bag, in addition to many more he found on the top and side of the hill. It took him ten minutes to prepare everything.
Once done, he started to write another weird symbol on different places around the hill with his blood.
"It's ready," after exhausting all his flowers, he went back to the central zone he cleared before in wide strides.
Just moments ago, he could hear the swift rustling noises of the leaves around, marking the arrival of his prey.
As he went back to the top, he found the area he cleared and left his blood marking its border showing little changes. Up there he found a faint glistering dome that appeared to cover an area of ten metres radius.
He was sure he was the only person able to see this. After all, this protective dome was made by his blood.
It was an invisible shield, created using old runic symbols of a long fallen spirit master empire. The bombs and the shield didn't consume his spirit force, but they consumed a big portion of his vitality.
At this moment, he was staggering to keep himself walking erect towards that dome. But once got inside, he couldn't withstand it anymore and crashed heavily on the ground.
He struggled to sit and tried his best not to close his eyes. The first thing he did next was to circulate his scarce spirit power inside his body.
One had to know that William obtained a huge encyclopaedia of knowledge regarding the spirit world. If he could produce two top grade training manuals for Berry to use on a whim, then he had more suitable and far formidable manuals for himself.
But his low spirit power was the main problem he had at the moment. Not to mention his spirit being in the mud phase. So, he only circulated his spirit power in the most simple and basic way.
*Screech!*
The monkeys announced their arrival by their distinguished voices. William wasn't worried about them following him inside the dome. After all, this invisible shield didn't only block vision, but all the five senses as well.
These scarlet monkeys were simple minded monsters. If faced with far intelligent ones, he might be worried about getting discovered.
Sitting up there allowed him to observe the large number of the incoming group of monkeys. He didn't know if he should laugh or cry, but the large amount of blood he used so far managed to attract not only one group but three.
He estimated his trophy this time to go to around three hundred monsters getting killed. Yet he waited, patiently letting the monkeys climb up and scout the hill with interest.
After all, once he started his attack, the monkeys far away would instantly retreat. Even if they were dumb, they still had their survival instincts.
So, he waited, patiently waiting for more monkeys to climb the hill. The monkeys acted like any typical monster, acting slightly cautious but still daring.
In less than a span of five minutes, the entire hill was filled with monkeys. They could smell blood but couldn't find any living monsters or humans here. Not even a corpse was found.
"Boom!"
As the entire hill was covered, it was time to hit them. He simply activated the blood link he got with the symbols he left behind. And the next moment lots of explosions appeared, wreaking havoc among the large number of monkeys around.
Even with such the weak strength he got, the many flowers he used and scattered all around turned the entire hill into a scorching piece of hell. William felt the entire hill trembling faintly under the might of his attack.
So, it was expected what happened to the monkeys. Those who got hit directly were killed. As for those on top of the hill, they panicked and ran all around, trying to get away by running through the scorching side of the hill painted with orange fire on such a dark night.
*Screech!* *Screech!* Screech!*
They screamed in pain before they all fell dead. William kept himself inside his invisible shield and waited for his vitality to recover.
His shield was able to stand almost for ten hours straight without problems. Yet if it was discovered by anyone, then this shield might only withstand attacks for much less time.
That was his sole worry, for the monkeys to accidentally discover the shield. But against his worries, the monkeys were only driven by their survival instincts, and ran all down the hill, to be killed by fire.
They were dumb monkeys indeed!
What he feared next was for such noise and blood scent to attract more formidable monsters. Even with the loud sound of the raging fire, he could hear some scary noises from time to time, coming from the direction of the forest.
Yet not a single monster dared to break through the thick veil of fire. The fire kept running wild for a long hour before it finally died down.
Yet the devastation left behind was really terrifying. An area of over a kilometre in radius was now painted in black, with many leftovers from the fire expanding to the areas of forest around the hill.
