At this time, there were less than four hours left before the arrival of the tidal wave. The density of the ominous creatures had increased significantly, and the price of fighting freely was rapidly increasing.
Most people already knew that the situation was not right, and they all shouted, "Retreat! Don't be greedy for those energy crystals!"
When the defending army returned to their positions, the defending army that was already prepared began to attack with the Pure Stone Arrow Rain that they had used in the previous battles. The sky was filled with Holy Light arrows, piercing through the sky and blocking the enemy's retreat.
At this time, these city defense army consumed war supplies, not their own. Because they couldn't participate in the free hunting, as long as they didn't die after the war, they could get extra energy crystals.
Of course, not everyone could join the city defense army. These people were all at the Venerable Realm, without exception. The selection process was very strict, so others could only be jealous of them.
Swish, Swish, Swish ~
Wave after wave of arrows rained down. If one looked at it from a third person's perspective, it would look like a meteor had exploded. The pure and holy arrows never stopped, and in the short time it took for an incense stick to burn, the number of Purity Stones consumed had reached a shocking five million.
Of course, outside the mountain city, a large number of energy crystals were also left behind.
In the lord's mansion, Zhang Xuanyu and the others were surprised. "Are those the so-called Clean Stones? This is a war of attrition! They don't look good at all. "
Luo Xiaobai shook her head. "You can't say that. This may be the specialty of this Chaotic Wasteland. What we fight is resources, but what we get back is also resources. It's equivalent to exchanging resources with these ominous creatures. But the resources in exchange can greatly help cultivators grow stronger quickly. "
Le Renkuang added, "I'm thinking, what if we run out of these stones? If they fight like this every hundred years, what about ten thousand years, a hundred thousand years? And this is just a city. "
Someone said, "Even the resources of the Chaotic Azure Sea can't be dug out. Besides, the outside world is vast, and there must be a lot of such Clean Stone veins."
Not only Zhang Xuanyu and the others were shocked, but even Han Fei and Tai Yuan were also shocked. Every second, tens of thousands or even hundreds of thousands of Clean Stones were consumed. At this rate of consumption, by the time the Tidal Wave arrived, at least a hundred million Pure Stones would have been consumed, perhaps even more.
About an hour later, the speed of the Clear Stone Arrows could no longer completely resist the attacks of these ominous creatures.
However, the guards of the mountain city had already made preparations. They had already laid down a large number of Clean Stone Mines that stretched for thousands of miles outside the mountain city. In the sky above the city, the Pure Stone Shield was ready.
"Bang, bang, bang ~"
When the sea of ominous creatures rushed over, the Clean Stone Water Thunder burst out, illuminating the entire mountain city. It was as if holy light had enveloped the earth. Most people could only see a vast expanse of white in front of them. They couldn't tell how many ominous creatures were in front of them.
However, the outermost guards were all ready for battle at this moment, and were only waiting for the guard captain's order.
Amidst the flashes of lightning, when the first ominous creature charged into the area within a hundred miles of the mountain city, there was a buzzing sound as a holy light barrier suddenly rose 2,000 miles away.
This holy light barrier enveloped the entire mountain city in an orderly manner. The defensive array of the mountain city had been activated half an hour in advance.
The kings all shouted, "Everyone, attack! The battle time is only half an hour!"
"Hoooooo ~"
"Kill!"
Ripples constantly appeared on the city-protecting array, which was caused by countless ominous creatures hitting the array.
However, these collisions and vibrations were rapidly decreasing. Han Fei and the others could sense that at the moment the city-protecting array was activated, a large number of ominous creatures actually took the initiative to avoid it. They no longer attacked the mountain city, and they didn't know where they were going.
Seeing this scene, Han Fei and the others couldn't help but breathe a sigh of relief. Sure enough, the ominous creatures were afraid of the power of the Clean Stone. When the entire city was enveloped by the light of the Clean Stone, they lost interest in the mountain city.
But Han Fei knew that more than ten years after the tidal wave, it was also the peak period for hunting. Although the tidal wave had passed, a large number of ominous creatures would stay in this sea area of the Chaotic Wasteland. These creatures would occasionally attack the city, but at that time, their numbers would not be as dense as now.
Therefore, the ten years after this war would be the ten years when the people in the city cultivated the fastest. It was even to the extent that a small portion of people would save some Purity Stones for hunting.
Of course, those ten years would also be the most dangerous ten years. In the ten years after the tidal wave and the tidal wave, it was very easy for powerful creatures to be born among the ominous creatures, and even some creatures in the Heaven-Opening State would be born.
After all, a large number of ominous creatures were not of the same species, and they would also devour each other.
Therefore, in the ten years after the war, only a small number of ominous creatures were killed by humans, and most of them were devoured by each other.
In the end, these ominous creatures would form some relatively powerful ethnic groups, which would give birth to experts.
The 2,000 kilometers outside the city were blocked, and the Venerables crazily attacked. This time, their purpose was to kill these ominous creatures, because the more they killed, the more resources they would get. The reason was that simple. If you didn't want resources, others would.
When nearly a million Venerable State experts rushed over, this kind of war was like a collision of steel torrents.
Someone cast a great technique to trap the ominous creatures and then purify them with Clean Stones.
Someone was directly penetrated by a dazzling light, and a large amount of black mist entered his body. In the blink of an eye, he fell into madness and attacked his companions.
Someone killed the ominous creatures, but died in the hands of others.
Someone attacked fiercely and fought three in and three out.
In fact, there were not many ominous creatures within a mere 2,000 kilometers. After a few rounds of attacks, the ominous creatures were all slaughtered.
When the army retreated, the city guards set up Clean Stones and Water Mines again, and Han Fei reactivated the great array to trap a large number of ominous creatures again.
Just like that, after repeating this process twice, a loud bang was heard, and the Tidal Wave finally came crashing down. A large amount of black mist directly enveloped the entire mountain city.
The guards all shouted, "Everyone, don't attack."
The city-protecting great array was divided into three layers. The first layer was 2,000 kilometers away, and this great array would inevitably be broken, because the coverage was too large, and the larger the coverage, the more Clean Stones would be consumed.
Therefore, the outermost great array would only last for two hours. And the duration of the tidal wave would be as long as two days or so.
An hour later.
Puff, Puff, Puff ~
Suddenly, someone shouted, "Look, the first layer of the city-protecting great array has opened."
The guard captain shouted, "All troops, prepare to attack."
When the first layer of the city-protecting great array was breached, it meant that this great array was not far from collapsing. And as more and more breaches appeared, more and more ominous creatures would rush out from the breaches. Of course, there was also ominous aura rushing in this time.
However, the amount of ominous aura was not very large. They could use the first layer of the city-protecting great array to launch the last round of attacks before it was broken.
In the array, the army was charging.
Outside the array, Han Fei tried to release his perception, only to find that once his soul touched this overwhelming ominous aura, it would be melted.
Half an hour later.
Just as the first layer of the Great City Barrier Formation was about to be riddled with holes, suddenly, there was a loud bang, and the formation cracked. Something suddenly broke through the formation. It was a head that was more than 300 meters long.
In the city, the kings who were not controlled by Han Fei all changed their expressions.
"Not good, there is a powerful ominous creature in this round. It's being born too fast."
Han Fei's puppets all shouted at this moment, "All troops, retreat."
Kacha!
The first layer of the array was collapsing rapidly.
The city-protecting great array was collapsing faster and faster. If they were not careful, the mountain city would suffer heavy losses. Han Fei conservatively estimated that at least 10% of the population would be killed.
And the Sword God and the others were still disguised as frogmen, so it was not very suitable for Han Fei to attack.
Beside Xue Fei, Han Fei shouted, "Blast it out of the array."
BAM ~
In the blink of an eye, Xue Fei's emperor might surged. He instantly slaughtered his way over with a thousand Purifying Stones in hand. He blasted out with a single strike, blasting the snake head away. At the same time, Xue Fei also rushed out of the array and fell into the black ominous aura.
Han Fei also wanted to take the opportunity to understand the strangeness of the ominous aura, so he also appeared outside the array.
However, Xue Fei relied on the Clean Stones to resist the ominous aura.
Han Fei's body was shrouded in holy light. This was the outbreak of the Heavenly Awakening Divine Technique.
Countless strong masters in the mountain city were shocked. Could it be an ominous creature in the Heaven-Opening State?
