After about half an hour of fighting, the battlefield was littered with corpses. The demon corpses were now trampled into a bloody pulp by countless cultivators. However, these demon corpses did not permanently disappear but would re-integrate into the soil and regenerate.
The reproductive ability of these demons was too strong, so even so, they could not be eradicated.
"Boom!"
Suddenly, a fierce explosion sounded, followed by a scream. A tall, burly man appeared on the battlefield, emanating a faint blue light.
This burly man was slaughtering the demons. This burly man was actually the guardian beast of this space, the core of this space, and the most powerful existence in the entire world.
"Roar~"
The guardian beast roared and opened its massive maw, biting at the demons. At this moment, the demons fiercely resisted and fought with the guardian beast. The defense of these demons was extremely strong, so even the guardian beast could not do anything to them.
Moreover, the guardian beast was being held back by the demons, allowing the demons to slaughter the territory wantonly.
"This guy should be the only Saint-tier existence in that world. It seems that all the Saint-tier demons in this world have been summoned here. It looks like the demons are preparing to attack in full force, wanting to destroy the territory. Unfortunately, they chose the wrong target." Zhou Yan watched the scene before him and sneered.
This guardian beast had actually surpassed the level of Transcendent Ninth Heaven. And during the previous battle, the methods displayed by the guardian beast were extremely peculiar. The demons could not harm the guardian beast, and this guardian beast seemed to specifically counter demons. Once touched by the guardian beast, the demons would almost instantly turn into blood mist. This was why these demons were desperately charging the defensive line of the territory.
"Hmph! Just a mere demon dares to provoke my territory, truly seeking death. Die!" Zhou Yan said and rushed towards the battlefield.
Behind Zhou Yan, one hundred and eight array flags fluttered in the void, exuding a solemn atmosphere. The Chixiao Sword in Zhou Yan's hand fiercely stabbed at the giant demon.
The demon leader also saw Zhou Yan but did not dodge. Instead, it charged towards Zhou Yan.
"Bang!" After a dull thud, Zhou Yan's Chixiao Sword collided with the demon. Immediately, a violent force spread from the point of their clash, stirring up a gust of wind that made it impossible to open one's eyes.
"So powerful." Zhou Yan sighed inwardly. In that exchange, Zhou Yan felt the demon's strength. This demon's strength had at least reached the realm of Transcendent Seventh Heaven.
"Roar!"
The demon leader growled and directly clawed at Zhou Yan. Zhou Yan hurriedly dodged. The demon's claws were as hard as steel, leaving five bloody gashes on Zhou Yan's shoulder.
However, Zhou Yan was not afraid, because he had also one foot into the realm of Transcendent Ninth Heaven. Moreover, this demon's strength was not much inferior to his, and was even slightly stronger.
Therefore, Zhou Yan took out his weapon. A spear appeared in his hand, and the spear danced with sharp gun shadows, thrusting towards the demon.
"Clang!" A crisp metallic tremor sounded.
The spear in Zhou Yan's hand was knocked away by the demon's claw, and several deep bloody holes appeared on the demon's claw.
Even so, the demon did not retreat but continued to attack Zhou Yan. Zhou Yan constantly maneuvered, avoiding close combat with the demon. Zhou Yan needed to conserve his strength and wait for an opportunity.
"Puchi!"
Another flash of sword light, and a red line appeared on the throat of the demon leader. Then the demon leader fell.
"This guy is really troublesome, but fortunately, reinforcements from our territory have arrived, otherwise we would be in big trouble this time." Zhou Yan breathed a sigh of relief.
The strength of these demons was very formidable, and they were fearless of death. The number of these demons was too large. If it were an ordinary person, they would have been killed by these demons long ago.
"Lord, are you alright?" a guard from the territory asked Zhou Yan with concern.
"I'm fine. Let's quickly evacuate this place and go notify the City Lord's Mansion. Tell them that the demons have begun to madly attack our army, and quickly dispatch more reinforcements." Zhou Yan said.
"Understood." The guard replied and immediately turned to notify others.
"Boom!"
Suddenly, a huge roaring sound came from the sky. The sound was deafening, making people's heads spin. Zhou Yan looked up and saw three giant black vortices appearing in the sky at some point.
The moment these three vortices appeared, Zhou Yan understood that these three vortices must be teleportation channels, but he did not know where these teleportation channels would lead.
At this time, some strong individuals from the territory could no longer stand it and rushed towards the vortex. They had to leave this place as soon as possible, as it was too dangerous here, and a slight mistake could lead to their demise in this vortex.
"Lord, I'm going first!" At this moment, a young man shouted at Zhou Yan and then jumped into the vortex.
"Hmm?" Zhou Yan frowned, then also jumped into the vortex.
Zhou Yan felt like he had traveled for a long time. Finally, his eyes brightened, and he saw a valley surrounded by dense forests. At this time, a group of people were gathered together resting. Upon seeing Zhou Yan appear, they also stood up.
"Lord, why are you here? This place is too dangerous," Li Mu said to Zhou Yan with some worry. Although it was already night, who knew if the demons would launch a night attack.
"I'm here to discuss the next steps with you. I have decided that we will turn this secret realm into our human territory. Are you willing?" Zhou Yan asked the people before him earnestly.
"Lord, you don't need to say more. We are all willing to join the royal family and be loyal to the empire," those people said one after another.
"We now have thirty-six million troops, led by four great princes. This is our trump card, so we need to unite and fight against the demon army together. Only then do we have hope of survival," Zhou Yan said.
