Sam went to the edge of the formation. Due to long term depletion of energy from the hydra, the formation has eroded.

But even after it was eroded, it is not easy for him to break.

His level of attainment in the formations and the inscriptions is not high enough for him to break the formation open

Even a stone wall which is tens of meters thick was tested with time and became as weak as a mud wall, digging a mud wall of that size isn't a normal person could do and Sam is in same situation.

But he didn't give up.

Sam thought about the energy flow in the formation and checked each and every spike. There are more than twenty chains which are acting as energy channels. There are a total of forty spikes out of which twenty of them are buried inside the earth acting as nodes.

He started observing all the nodes individually to where the formation is damaged causing these energy loop holes.

Even if he wants to deal with this, he has to take care so that there wouldn't be any damage on him due to energy back lash.

After a long time, he found the spot where the energy is depleted and the node with which he can work to destroy the formation without much backlash.

He placed his hands on the ground near the spike, and slowly started eroding the earth around it. If the node is removed the formation will be destroyed, then he can surely make use of it to store away, but he needs to be prepared to face the rush of the water as well as the energy back lash.

Sam immediately wore his helmet back and kept the hoverboard back inside the storage.

Sam worked more than ten days, to completely take away the earth and rocks. The spike is buried vertically. It is more than ten feet long and more than eight feet is buried.

His mental energy was used up a lot after making some rocks into powder and the fact that spiritual energy is concentrated on the rocks near it is not helping. He will face minor back lash every time he unearthed some part of spike and he needs to recover.

In this way, he is dividing the backlash into minor parts and taking it on, if he were to pull it all at once, with the depleted formation, even though it might be possible, he will definitely have to face major backlash and under this sea, he might even die.

He has to take care that the energy spike wouldn't be destroyed or the runes will be damaged, that is why he worked around slowly and now he is at the final step.

Sam finally placed his hand on the last piece of the rock and another hand on the spike, and after destroying the rock, the spike was finally free, but he could visibly see the formation being destroyed slowly.

The huge force of water came inside, but Sam was also fast, he immediately started storing the chain inside his divine dimension and while the water is flooding in just before drowned the skeleton, Sam reached the skeleton and stored it in.

If he it wasn't for the fact that the formation was damaged a lot and the energy source which is hydra itself is completely depleted, he would have never had a chance to make it with his current level.

He also has to thank all the people who left this place alone. Maybe a person beyond Grand level cultivation might have been able to make it if he is water type mage and has elemental fusion.

If he could take some precautions against the poison, maybe they might have a chance to encounter the formation even if they weren't able to identify it immediately.

In this way, other powerhouse wouldn't leave it alone.

Sam was sure that if there are any resource used for cultivation had appeared instead of mutated water creatures, they would have definitely ventured in even with the risk of poison.

But since there was nothing else and all the people who entered the zone ended up dead, they left it alone.

Sam really did feel grateful for them for leaving

He let the water drown him first instead of struggling and went along with the flow, but he wasn't throw far away and still stayed in the vast rocky terrain.

After stabilizing for a bit, he went upwards with full thrust

He is faster when coming up than when he went down.

But he didn't come up to the surface directly, because the indigo patch was destroyed due to Sam taking away the formation. This indigo water was diluted and the whole sea region became indigo but the colour was a lot lighter and the water was close to normal.

In a few days, the water might even turn back to normal again.

But if he goes out now, he might have to face the people who are on the top and witnessed the scene.

He stayed underwater and travelled near the coast line as he went away from the city. After he reached the coast near woods, Sam came out of the water and removed his suit.

After wearing his usual clothes, he didn't take out the Harbinger, but called out Sky and soared higher to get the direction of city. And soon he is on the way back to the Indigo sea city.

This trip was way beyond profitable and it is more or less time to move to next city.

Sam came back to the vicinity of the city and went to the place where Jack and Jasmine camped.

When he was there, Jasmine is playing with ape. She sat on ape's shoulder and was eating a fruit.

When Sam came, she came down and ran over to greet him.

He just smiled in reply. At this moment Jack wasn't in the camp, jasmine said he went to hunt.

After a while, Sam brought a Green horned deer with him, he greeted Sam.

"Is your work complete?"

"Yeah. We can leave today."

After that short exchange, all of them sat to eat.

Later, they packed everything up, Sam took Yanwu and Sky out along with Harbinger.

Soon, three of them are soaring towards their last Count city and that is the Cougar city.

This city is a bit different because, the city wasn't named after its surroundings or resources, rather it was named after the noble family who holds the count title. The Cougar city is under the jurisdiction of the Cougar family.

They are also first-generation nobles who earned their title during the establishment of the empire just like how the Blue flame city was named.

Within three days the three of them are near the city. It has been only a little more than three months since they started the journey to clear three count cities' underground forces.

Now, all they have to do is deal with the Cougar city and wait for the remaining people to come. Then their mission can be considered complete and they can return to the Blue flame city.

When they are near the vicinity, they landed and started walking, but in the middle of their short journey in which, ape is working on finding some trees and herbs, they smelled something very ominous.

There seemed to be a thick blood smell, nearing them and the ape became more sensitive, because blood smell doesn't feel delicious at all.

Then suddenly a blood red figure stopped them in their tracks. It is like a lump of blood red matter with two arms. It is five feet tall and there are two hollows on its 'face' which seemed to be the eyes.

Sam never saw this before, but Jack seemed to know about this.

"Blood spirit ghoul." When Sam heard this, he furrowed his brows.

But there is no more time to get answers as the ghoul started attacking them.

Sam deliberately blocked the punch, the body of the ghoul seemed to be in semi solid state, but the punch felt like he was hit by a lump of solid iron.

He took a step back, Jack started fighting it with sword and soon he finished the fight with a stab. The ghoul doesn't seem to be the strong.

Sam walked towards the ghoul and he saw Jack taking out his sword and at the tip of the sword a round shaped red coloured gem like thing was present.

Seeing Sam walking towards him, Jack said.

"My mom said to me about the Blood ghoul and apparently, the person who killed my father was one who uses the blood spirit ghouls.

They are actually one of the creatures created by most vicious of methods.

These ghouls are formed from the blood of the deceased people, people filled with the resentment.

The people who were tortured to extreme and slaughtered at a same place will have a collective resentment towards a single person, their blood essence will gather together and all their negative emotions along with the spiritual energy will form this blood core made of those blood essences.

But the maker will mark the blood core with his spiritual brand and control it, but this seemed to be a stray one."

When Sam heard Jack's explanation, he was surprised. He never expected that he would encounter something like this here.

He crouched down and placed his hands in the puddle of semisolid blood. It can be called as condensed blood. But that is not what surprised him most.

The most surprising thing is there is a metal that is on par with the meteorite sand completely dissolved in the blood and that is none other than the Blood iron.

Yes, the iron that is present in human's blood. Since, the blood along with a person upgrades with a cultivator, the iron in the body also generates that quality, but the only difference is the Blood iron is upgraded with the Blood essence only.

So, if a person forges a blood with this iron, he or she has to walk the path of slaughter to improve the grade of the weapon, they feed on their enemies' blood essence to improve the grade.

The acquisition of the blood is also quite inhumane, that is why even though the blood iron is not scarce, it is not seen anywhere at all.

He is surprised that the Blood ghouls will use this Blood iron to attack.
