Zhou Chun had long conducted a thorough study of the geographic environment of the Great Zhou Kingdom.
Therefore, he knew that to the north of the Great Zhou Kingdom, there was a body of water known as Black Mist Marsh, where numerous Demon Beasts nested and dwelled.
It was undoubtedly most suitable for the Silver Lightning Python Baibai to undergo its Dragon Transformation.
Once the transformation was successful, it would definitely master both the Thunder Escape Technique and the Water Escape Technique, making it difficult for any Golden Core Stage Cultivator to capture it even if they appeared.
Over a month later, Zhou Chun arrived at the famously known edge of Black Mist Marsh in the Great Zhou Kingdom.
Unlike the vast waves of Dragon Abyss Marsh, Black Mist Marsh was a marshland with various types of aquatic plants growing over most of the water surface.
Most of the area was shrouded in gray-black fog year-round, a type of toxic miasma that not only poisoned the flesh but also corroded and disrupted the Divine Sense.
Thus, cultivators could not maintain their Divine Sense detached from their bodies as usual after entering; otherwise, their Divine Sense would be corroded and consumed very quickly, forcing them to leave and rest shortly after.
Because this black fog was hard to dispel, even though the Black Mist Marsh was known to harbor many rare treasures, no power in the Great Zhou could occupy this place.
This unique environment made it a paradise for Demon Beasts and also a hiding place for some notorious Bandit Cultivators.
However, for Zhou Chun, aside from the corrosive effects of the black fog on the Divine Sense, which he could not avoid, he was not at all worried about the fog's impact on his physical body.
With the Wood Charm Spirit Pet by his side, such natural toxic barriers were hardly able to harm him.
Finding a secluded spot that didn't draw attention, Zhou Chun directly summoned the Silver Lightning Python Baibai and rode it into Black Mist Marsh.
The black fog of Black Mist Marsh had much less impact on Demon Beasts than on Human Cultivators, as the Demon Beasts inherently had strong bodies and high resistance to poison.
The local Demon Beasts were already adapted to the existence of black fog, and some even manipulated the black fog to aid them.
The Silver Lightning Python Baibai was now just one step away from transforming into a Flood Dragon and reaching Third Order, thus its strength could be considered powerful in the Black Mist Marsh.
Using it as his Mount Beast, Zhou Chun encountered no sneak attacks from any Demon Beasts along the way.
After searching within Black Mist Marsh for three days, Zhou Chun finally found a satisfactory location.
It was a small island deep within the swamp, with many large trees that resembled banyan trees growing on it, their leaves gray-black and quite broad, with numerous aerial roots hanging down from them to the ground, making them look like demon trees from afar.
The island's spiritual energy was extremely rich, even more so than at the Zhou Family's Jiufeng Ridge mountain gate.
Many Demon Beasts inhabited the island, among which the true lord was a Third Order Demon Beast.
This Third Order Demon Beast seemed to be a lower-tier one, but its appearance was extremely bizarre.
It had a body like a lizard, a neck and mouth like a snake, and a tail like a crocodile, plus it had spines like those of a Spinosaurus growing along its spine up to the back of its head.
Even after seeing many Demon Beast catalogs sold in the Great Zhou Kingdom, Zhou Chun could not identify this Demon Beast.
However, he knew that the Demon Beasts in Black Mist Marsh were generally stronger than those outside.
Therefore, he took no chances and directly released his Third Order Wood Charm.
The lush vegetation on the island, although the rotting silt and animal carcasses underneath the aquatic plants emitted foul smells, were barely considered home ground for the Wood Charm.
When Zhou Chun released the Wood Charm, the Serpent Lizard Beast that was confronting him sensed a threat and couldn't help but launch an attack.
It spat black venomous water from its snake head towards Zhou Chun, with black fog swirling around its body, immediately forming a dense black fog domain that concealed it, making it difficult to see its true position.
Facing the attack of the Serpent Lizard Beast, Zhou Chun merely waved his sleeve and summoned the "Blackwater Profound Tortoise Shield," releasing a black light screen to protect himself within.
The black venomous water spit by the Serpent Lizard Beast was not weak; it landed on the black light screen and immediately corroded it, emitting black smoke and dimming the spiritual light significantly, but still far from breaking the shield.
Meanwhile, the vegetation around the initially concealed Serpent Lizard Beast suddenly grew wildly, binding it in the blink of an eye.
At that moment, a golden Sword Qi flew through the mist from outside, piercing through the Serpent Lizard Beast and creating a bleeding hole, with the sharp Sword Qi wreaking havoc inside its body, slashing its flesh into countless pieces.
This attack greatly terrified the Serpent Lizard Beast, which urgently burst forth the power of its Demon Core from within its body, its black spiritual energy surging, rapidly crushing the Sword Qi forcing it out, and also shattering the green vines binding it.
Just as the Serpent Lizard Beast broke free and was about to deploy another technique, several waves of white chilling air instantly pierced through the black fog and landed on its body.
In an instant, a layer of ice formed on its huge body, the terrifying power of frost not only freezing its body but also almost freezing its Demon Core.
Then the golden Sword Qi fell into the black fog again, penetrating the brain of the Serpent Lizard Beast with a single strike, completely severing its life force.
In this way, a lower-tier Third Order Demon Beast was virtually powerless to fight back, being instantly slain by Zhou Chun, not even having a chance to self-destruct its Demon Core before dying.
