The personnel of the Quartet Battalion are all the same, each with 10,000 ordinary soldiers, and 2,000 warriors at all levels, most of the survivors who have not been infected with corpse poison at this time are warriors guarding Beiguan, they all have aura cultivation, and they have stronger combat effectiveness than ordinary soldiers, and the most important thing is that aura cultivation has brought them night vision ability, and they can clearly see their opponents in the dark night.

Ordinary soldiers are not as fortunate as warriors, they have no night vision, they are unable to effectively dodge and counterattack in the chaos, and the enemy is all corpsed and their own soldiers, dressed exactly like them, which also makes it more difficult for them to identify their opponents and respond effectively.

Since Xuanwu had already lost the sky, his defensive front moved forward towards the barrier as a whole, and a large number of Tiangang crossbows and earth evil bows were arranged around the barrier, in addition to many catapults throwing boulders and gunpowder, and the fighting was mainly concentrated around these large weapons at this time.

The change in the camp of the Northern Army is naturally the work of the outside world, and its purpose is undoubtedly to disrupt the position of the defenders, cooperate with the loosening of the enchantment that will occur next, and create an opportunity for the remnants of the demon clan sealed in the other world to get out of trouble, and the general of the North Pass undoubtedly guessed this, so he ordered the rest of the people to stick around large weapons such as Tiangang crossbows and earth demon bows to ensure that once the enchantment is loosened, it can be blocked at the first time.

From a purely tactical point of view, this was the correct approach, but it also had the serious consequence that soldiers and warriors who were not infected with the corpse poison were limited in their movements, unable to effectively evade and defend, and indirectly increased their own casualties.

Just when Wu Zhongyuan was eagerly observing the situation in the field, Li Tai shouted again, "All corpse mutants will be beheaded, don't hesitate." ”

While shouting an order, Li Tai urged the Qinglong Armor to lift off the ground and fly westward.

After Li Tai lifted into the air, he found that Wu Zhongyuan was on the battlefield in person, and hurriedly turned in the air and came to Wu Zhongyuan's approach, "I have seen the saint, the enemy is prepared, there is likely to be an ambush lurking in the forest in the distance, and his subordinates are about to go to inspect and inspect." ”

Wu Zhongyuan didn't answer, just nodded.

Seeing that Wu Zhongyuan had no further instructions, Li Bei arched his hand at Wu Zhongyuan, and then urged the Qinglong Armor to fly west.

Although Wu Zhongyuan's face was as usual, he seemed to be very calm, in fact, only he knew that he was not as calm as he appeared, and it was the first time he had seen such a tragic and strange melee fight, which had exceeded his previous understanding of war, he didn't expect that the enemy would really do everything, and even used corpse poison, you must know that corpse poison is a more despicable means than biological weapons, and the enemy has gone beyond the scope of war and has become a genocide.

After an anxious groan, Wu Zhongyuan calmed down, sensed and summoned Qi Qi, Xuanwu's funeral heaven made the defense of Beiguan weak, and Qi Qi was not afraid of poison, and at this juncture, Xuanwu could temporarily defend Beiguan on behalf of Xuanwu.

After sending out his thoughts, Wu Zhongyuan teleported and disappeared and appeared in Xiguan.

The situation in Xiguan is very similar to that of Beiguan, there are also a large number of soldiers who have undergone corpse mutiny, but compared with the chaos in Beiguan, the situation in Xiguan is slightly better, the warriors and soldiers who have not been infected with corpse poison have withdrawn from the barracks, relying on the horse fence outside the barracks, the corpse soldiers are blocked in the barracks, but the soldiers and warriors who safely withdrew from the camp are less than fifty percent of the total number, the Taurus warriors led by Jiang Nan have participated in the battle, and all of them have entered the camp full of corpse soldiers, the defenders of Xiguan are all from the cattle clan, and the Taurus warriors have to endure the grief in their hearts in order to clear the hidden dangers, and the long knives are slashed, and the brothers and sisters are killed。

Because the corpse mutiny occurred in the camp of the defenders, the enchantment area did not suffer, and it was not seen for several months, and the white tiger, which was already old and decrepit, was getting older and older, and was already skinny and skinny, and the white tiger did not participate in the changes that happened in Xiguan, and was still lying on the huge bluestone, lowering his eyebrows and closing his eyes, motionless.

On the right side of the bluestone are tied two goats, and on the left side of the bluestone are two wooden barrels, which should contain soybean juice and pig blood that can replenish its golden gas, but the two barrels are full, and then look at the place where the sheep are bolted, there are a lot of sheep dung balls, all of which indicate that the white tiger has not eaten for a long time.

Not long after Wu Zhongyuan appeared, a figure flew from the west, and shouted urgently over Dexi Pass, "It's not good, there are demon ambushes hundreds of miles away." ”

It was none other than Jiang Zhen, the prince of Jiang, who was assisting Jiang Dahua in defending Xiguan, but Jiang Dahua had not yet arrived at this time.

This warning voice alone shows Jiang Zhen's courage and lack of strategy, and words like bad things should not be said, which can easily exacerbate the tension and panic of the Xiguan defenders.

Jiang Zhen didn't find Wu Zhongyuan, and rushed into the battle group after shouting, Wu Zhongyuan's long sword was in his hand but he didn't participate in the battle, he held the long sword to supplement the spiritual energy depletion caused by the previous large-scale teleportation, and now it was just a prelude to the big war, and the real bloody battle had not yet begun, and it was not yet time for him to make a move.

After a moment of stay, Wu Zhongyuan teleported to Nanguan, Nanguan also had a serious corpse mutiny, Zhu Qianwei, Wu Qin, Wu Di were all here, Gao Zhan also led the wolf army to rush over, three thousand elites were all dispatched, but they did not participate in the battle, but stayed on the edge of the jungle in the northwest of Nanguan, the rapid undulating abdomen and the long tongue that stretched out indicate that they had just arrived, and had not yet been rested and breathed.

Gao Zhan didn't seem to have come back to his senses, until this moment he was still confused, standing in front of the wolves with a lynx dragon stick in his hand and looking around, seeing Wu Zhongyuan appear, he hurriedly came in the air, "My lord, what's going on?"

"The enemy has cast corpse poison, and the Quartet camp has suffered heavy losses," Wu Zhongyuan said in a deep voice, and after speaking, he raised his breath and spoke, "The corpse poison comes from zombies, zombies are under the control of the ghost clan, this attack on the ghost clan is the culprit, there must be ambushes on the periphery, there will be a bloody battle today, give me strict guards, and I must not let the ghost king escape!"

Hearing Wu Zhongyuan's shout, everyone below was shocked.

Compared with the other three levels, his own side invested the most troops in Nanguan, not only a hundred purple qi wizards, but also four auxiliary princes and three thousand elites of the wolf clan, and the Vermilion Bird is still there, and the war will start later, Nanguan does not need him to be distracted.

When everyone shouted yes, Wu Zhongyuan teleported again and appeared in Dongguan.

The reason why he finally rushed to Dongguan was because in his opinion, compared with the other three passes, the situation in Dongguan should be better, because the eyes of the Protoss are above the top, and the relationship with the other Dao is not good, and it is impossible to join forces with the three clans of demons and demons, even if the defenders have a corpse mutiny, it is also a means for the enemy to disperse the forces of the human race.

But the truth is very different from what he imagined, the battle situation in Dongguan turned out to be the most severe among the four passes, the whole camp was full of corpses, tens of thousands of soldiers were almost wiped out, and the people who were still alive were all warriors wearing various cloaks, and the firearms guards led by Wang Xinran had become one with the living defenders, but they were not in a hurry to use firearms, but each held a long knife and slashed at close quarters.

After a short period of observation, Wu Zhongyuan flew westward, found two hundred miles, and then diverted to the north, and returned to Dongguan from the dense forest in the north.

While he was inspecting the northwest side, Zhulang and Yu Qingdu also came from their respective cities.

Seeing the two of them, Wu Zhongyuan shouted and asked, "Two princes, can you see an ambush on the way here?"

"No, I didn't. The two spoke in unison.

Hearing the words of the two, Wu Zhongyuan knew in his heart that the Protoss really did not join forces with the three demons and demons, and the corpse changes that occurred here were only deliberately done by the other three in order to disperse the forces of the human race.

Just as he was trying to teleport away, a yellow light suddenly appeared in the Dongguan enchantment, and seeing that the enchantment was loosening, Wu Zhongyuan hurriedly stabilized his body and watched intently.

At the moment when the barrier loosened, the pool where the green dragon was dormant was flooded, and at the same time, an aura barrier appeared out of thin air, covering the area where the barrier was located.

The loosening and opening of the barrier did not happen overnight, but rather a repetitive process between opening and closing, much like an incandescent light bulb flickering on and off before it broke, and the whole process lasted about thirty seconds before the barrier was fully opened.

However, after the enchantment was opened, the Protoss did not try to conflict, let alone the Protoss army, and not even a single mouse escaped.

After observing for a while, he didn't see the Protoss taking the opportunity to break through, and the soldiers who saw the corpses were about to be cleared out, Wu Zhongyuan did not continue to stay in Dongguan, Li Tai was patrolling around when he left Beiguan before, and he teleported away without waiting for Li Tai to return, so he was not sure whether Beiguan was the same as Nanguan and Xiguan, there were ambushes lurking outside.

After appearing in Beiguan, he found that the barrier of Beiguan had also been loosened, and Qi Qi had already been called to be in place at this time.

The defenders who had not been infected with the corpse poison and the Golden Crow warriors were still slashing and killing the corpse mutated soldiers, and due to the addition of the Golden Crow warriors, the defenders gradually reversed their disadvantage and stabilized their position at this time.

Li Tai and Li Wanzi, who came later, did not participate in the battle, but hovered in the air and talked eagerly.

Wu Zhongyuan moved out of thin air, and before the two of them died, "Is there an ambush on the periphery?"

"Yes," Li Tai replied, "A hundred miles away, within three hundred miles, there are all demon races, mixed breaths, and many species. ”

Li Tai said, Li Wanzi said, "The mountains are high and the forests are dense, so you can't enter and kill them in vain, you can only defend the North Pass and wait for them to take the initiative to attack." ”

"The enemy is bound to win. Wu Zhongyuan said in a deep voice.

The two nodded heavily, then turned their heads to look at Wu Zhongyuan, waiting for him to give an order.

Wu Zhongyuan didn't speak immediately, it was early December at this time, and there were still twenty days before the Divine Beast Funeral, no one would have thought that the enemy would choose this opportunity to break through in a big way, according to ordinary people's thinking, it would be easier to break through after the Divine Beast Funeral, but the enemy did the opposite, which caught them off guard.

After groaning, Wu Zhongyuan Zhengse said, "They are definitely not a feint attack this time, today the three clans of demons and demons will come out, cheer up, and prepare to face ......"
