Although he knew that Beiyang City was in danger, Han Feng still tried his best to kill the monsters on the city wall.
As time passed, more and more monsters gathered under the city wall, and the city gates rumbling and shaking violently were hit.
Even the entire northern city wall began to shake under the crazy impact of the monsters.
Even though the city guards stood up to stop them, more and more powerful monsters climbed up the city wall.
At this moment, Han Feng held the Overlord Spear and jumped directly onto the wall. As he came and went, countless bloody gun shadows swept across, punching through and flying away many monsters, strangling them all.
Nangong Qi, Lu Yun'er and Jin Buhuan also used their own methods to kill a large number of monsters.
Even Jiang Biao and other four thousand households led dozens of hundreds of households to join the camp to encircle and suppress the monsters at the top of the city.
The people and the monsters fought hand to hand on the city wall, killing each other like crazy.
However, as time passed, more and more Chen-level monsters attacked the tower.
Nine hundred people died unfortunately, and more than half of them were injured.
Han Feng even sensed that among the monster beasts, there were several late-stage Chen-level monster beasts, quickly approaching the city wall.
Seeing that the situation was getting worse, everyone suddenly heard a roar coming from the sky.
However, a large number of birds and beasts flew out from the Beiyuan Forest and gathered in a flock in mid-air.
Just before nightfall, these birds and beasts gathered into a huge dark cloud and shrouded it over Beiyang City.
"Flying monster!"
Han Feng's pupils shrank, and his heart became more solemn. Although Beiyangguan's troops were weak, it could be said to be a strong city. Even if monsters attacked in groups, it could still stand firm.
But no matter how high the city wall is, how can it defend against these flying monsters.
At this moment, two thunderous roars came from the group of monsters below.
A huge rhinoceros with a green body, a single horn, and a body as big as a fortress, covered in thick armor.
His eyes flashed with purple light, and with a roar, he directly knocked away a group of monsters blocking the way in front of him, and slammed one head against the wall of Beiyangguan.
The extremely hard horn actually caused the city wall to shake and a crack appeared.
At the same time, among the monster beasts on the other side, there was a vicious dog with two heads, as huge as a yak, and covered with red hair.
At this moment, he jumped up high and sprayed out a huge fireball from his mouth, which instantly bombarded the city wall. It actually swallowed up two Chen-level cultivators and turned them into ashes!
Han Feng immediately recognized the two monsters.
"Bixia Lingxi, double-headed red flame mastiff!"
The auras of these two monster beasts have unexpectedly reached the realm of Chen-level nine stars. Their strength is amazing!
The appearance of two Chen-level peak monsters, coupled with the flying monsters overhead, enveloped them at extremely high speeds.
Seeing that there were many monsters climbing up the city wall quickly, the city guards on the city tower couldn't help but feel a sense of powerlessness that "the building is about to collapse", and gradually felt fear and uneasiness in their hearts.
Seeing this situation, Han Feng was heartbroken and planned to use his mental power to strangle more monsters.
However, Wei Zhengping, who was silent at the top of the city, suddenly crushed a jade talisman in his hand.
The moment the jade talisman shattered, four khaki light pillars shot up into the sky from the corners of the four walls of Beiyang City.
After rising to a height of 100 feet, the four light pillars converged towards the center, and finally condensed into a dazzling yellow light group.
A layer of rich yellow light spread out like a curtain of water on the surface of the light group, covering the entire Beiyang City in an instant.
The group of monster beasts a hundred meters away from Beicheng were immediately blocked by this yellow light.
The torrent of beasts collided with the seemingly fragile light curtain, but it only caused a few ripples in the light curtain, unable to shake it at all. The torrent of thousands of monster beasts was actually cut off by the light curtain.
At the same time, the hordes of flying monsters in the sky were also blocked by the light curtain.
They launched a fierce attack on the light curtain, but they could only cause ripples, leaving the light curtain unscathed.
Seeing this scene, Nangong Qi, whose pretty face was stained with blood on the city wall, couldn't help but brighten her eyes and said in surprise.
"Big Five Elements Earth Armor Formation!"
Lu Yun'er withdrew the blood-stained golden mace and said with a surprised look on her face.
"What a powerful formation, it can actually block the impact of the beast tide."
Nangong Qi explained.
"In our Qianlan Empire, every important border town must have a city defense formation. Although Beiyang City has always been stable, it also has a city defense formation.
This large five-element earth armor formation is a fifth-level magic formation with astonishing defensive power. Even star-level monsters cannot break through it for a while. "
After hearing this, everyone on the city wall suddenly felt relieved.
But Han Feng was confused.
"In that case, why not activate the magic circle earlier?"
Everyone was stunned when they heard this.
Yes, if the formation is activated in advance, there is no need to sacrifice so many soldiers.
At this moment, Jiang Biao, not far away, gave everyone the answer.
"Because the operation of this formation requires a large amount of energy. Our energy reserve in Beiyang City is enough to operate the formation for half a day at most. Once the energy is exhausted, the formation will collapse on its own!"
Everyone's expressions changed immediately after hearing this. The formation could only last for half a day.
No wonder Wei Zhengping was unwilling to activate the formation until now.
"Don't think so much now, kill the monsters under the tower first!"
Jiang Biao's words brought everyone back to reality.
At this moment, there are still thousands of monsters trapped under the city tower between the city tower and the large array of light curtains, including the two Chen-level peak monsters.
No matter how long the formation can last, the current crisis must be resolved first.
At that moment, all the city guards were on the tower, and there was another frenzied strangulation.
From a high position, he used city defense equipment to strangle most of the monsters under the city tower.
Jiang Biao and other four thousand households, together with Han Feng and four other city guards, as well as all the city guards who had reached the Chen level or above, opened the city gate directly and rushed out.
After strangling many low-level monsters, everyone moved towards the two Chen-level monsters.
Although the Chen-level peak monsters are powerful, the strength of everyone is also not weak, and there are many people, plus there is fire support from the tower.
The crowd swarmed forward, spent a stick of incense, and finally killed the two Chen-level peak monsters under the city gate. They then simply cleaned up the battlefield and rushed back to the city tower.
At this moment, more than two hours have passed since the beast tide broke out, and night has completely enveloped the earth.
With the protection of this five-level city protection formation, there was finally a brief peace outside Beiyang Pass.
On the city tower, the corpses of monsters and soldiers had been cleaned up, but there was a lot of blood left on the ground. It was unclear whether it was left by monsters or soldiers.
Many soldiers collapsed on the ground from exhaustion. Some practiced cross-legged and took the opportunity to recover their spiritual power, while others simply fell asleep.
Others couldn't help but groan in pain because of their injuries.
The tower where the shouts of killing had been loud just now became dull, and the smell of blood was everywhere.
At this moment, Jiang Biao and four others came to Wei Zhengping and reported the number of casualties.
After only resisting the attack of a wave of beasts, the Beiyang City Guards were damaged, nearly a quarter of their strength.
Jiang Biao couldn't help but ask.
"Lord Guard, when will reinforcements from Yumen County arrive?"
Wei Zhengping frowned.
"When I discovered the beast tide just now, I had already ordered someone to send an urgent battle report, but the reinforcements are the fastest and I'm afraid they won't arrive until noon tomorrow."
When everyone heard this, their hearts sank at the same time.
The formation can only last for half a day at most, and it may be difficult to last until reinforcements arrive.
After a moment of silence, Wei Zhengping spoke.
"Don't be discouraged, we can use the power of the formation and manpower to fend off the monsters in turn.
In this way, the energy consumption of the formation is alleviated and it should be able to last until reinforcements arrive. "
After hearing this, everyone was refreshed and felt that this method was feasible.
Although fighting monsters with manpower will inevitably involve sacrifices, it is still better than the result of the formation disintegrating and Beiyang City falling.
At that moment, Wei Zhengping ordered all the city guards to rest on the tower, heal their injuries and practice.
After two hours, he will withdraw the formation and let the entire army resist the monster for an hour.
After everyone received the order, they raced against time to recover.
Although Han Feng had consumed a lot just now, his Dantian reserves were now astonishing, and he was not in a hurry to practice. He just stood on the tower and looked into the distance.
Outside the formation, more and more demonic beasts were gathered, surrounding the formation's light curtain. They were still attacking crazily, causing ripples on the light curtain.
As time went by, the attack of the monster beasts not only did not weaken, but became more violent.
Han Feng had already sensed it, and no less than a dozen large monsters of the late Chen level were mixed in with the group of monsters, attacking the formation.
More flying monsters also gathered in the void, swooping down and slamming into the formation.
Seeing all this, Wei Zhengping and the four thousand households' faces became increasingly ugly.
This beast wave is more terrifying than they imagined, and the time that this fifth-level formation can sustain may be greatly shortened.
Just when everyone was worried about the situation in front of them.
Suddenly, in the direction of Beiyuan Forest, three terrifying auras rose into the sky and swept across all directions.
"boom……!"
Under the terrifying aura, even though they were separated by a five-level formation, everyone on the tower still felt trembling and their hair stood on end!
Han Feng's heart also trembled, and he couldn't help but change his face.
"Hiss...the aura of the star-level demon!"
