The alien army is obviously prepared, the black pressure is pressing, from all sides to surround the Yanmen Pass, the garrison on the battlefield is almost the enemy's back, bearing the enemy's attack from three sides, in this situation of the enemy is outnumbered, any further delay will only end up in the end of the whole army.

When the two of them went to the city, Xiao An went to report what happened at the inner city gate to Sun and Yang, and then saw Lord Sun turn his head to look at Murong Xiu, and his demeanor was a little more appreciative.

"Collect the troops, the whole army retreats to Yanmen Pass, and all the immortal cultivators climb the city wall, and set up a ten-zhang forbidden area in front of the city for me. ”

Sun and Yang, as the principals of Yanmen Pass, did have their own merits, looking at the overall situation on the city wall, seeing that the elite of the alien army was exhausted, and after careful planning, they immediately issued an order to all the garrisons to withdraw their troops.

Since it is impossible to do something, take the light of it and exchange the minimum price for the maximum benefit. Collecting troops does not mean that the Zhongzhou side admits defeat, because there is also Yanmen Pass as a barrier, it is easy to defend the city, but it is difficult to attack the city.

Moreover, there are hundreds or thousands of immortal cultivators here on the Zhongzhou side, which are much higher than the alien side in terms of quantity, and they may not be able to take the alien army on the battlefield, but they are all placed on the defense of the city, even if the alien army has the same number of immortal cultivators, they may not be able to attack it.

After receiving the order, the army outside the city retreated to the city in an orderly manner, and was still able to maintain a complete formation during the period, which shows that these garrisons are well-trained on weekdays, and there is no panic in the life and death situation.

At the same time, the immortal cultivators jumped onto the city wall like flying locusts, and once they found that an alien army had entered the attack range, they killed them on the spot.

What shocked Murong Xiu the most was that behind these immortal cultivators, there were nearly thirty array masters, although the cultivation realm was not very high, but with the protection of their talisman array, it was difficult for ordinary arrows and spears to bring any damage to immortal cultivators.

It's a pity that among these array masters, he didn't find the existence of a rune array division.

In addition, a large number of Zhuang Khan, who held heavy weapons and wore heavy armor, guarded by these formation masters, almost all of them were one-on-one, with such a double protection, it was difficult for these immortal cultivators to die.

Seeing this, Murong Xiu finally breathed a sigh of relief, such tactics and equipment are the backbone of the garrison of Yanmen Pass, and with their existence, Yanmen Pass will be impregnable.

"Stinky boy, did you also guess the Donghu and Xiongnu alliances?"

The garrison outside the city has already retreated into the city, and at this time it is resting on the street not far from the city gate, and within ten zhang of the city wall has also become a forbidden area under the indiscriminate bombardment of the immortal cultivators, and the alien army does not dare to rush in easily, taking advantage of this gap, Lord Sun came to Murong Xiu's side.

"Could it be that it's really a coalition army?"

Murong Xiu's heart was shocked, and he looked at the alien army under the city again, whether in terms of clothing or weapons and horses, he still didn't see any difference.

"I know that you stinky boy who doesn't have any hair can't tell the difference. ”

Master Sun smiled very proudly, he had only only seen Murong Xiu once, but because of Murong Bai, he always couldn't help but tease Murong Xiu, and Murong Xiu was helpless about this, and then he saw him pointing to the left side of the alien army to explain.

"Teach you the easiest way to distinguish, see, here is the army of the Huns, and on the east side is the men and horses of Donghu, take a closer look at their quiver. ”

Although Donghu and Xiongnu were nomads living on horseback, the Xiongnu were much more fierce than Donghu, whether it was armor or riding boots, or even quiver was used to adding pig iron, and Donghu preferred to use pure animal skin, which was soft and easy to carry, and would not affect all kinds of movements. ”

After Lord Sun said this, Murong Xiu suddenly discovered the difference between the two sides, although with the naked eye, the armies of the two clans overlapped, but in fact they were clearly distinguished, the Xiongnu were in the west, and the Donghu was in the east.

"It's too confusing, isn't there any other way to tell the difference?"

This is Murong Xiu's intention to make things difficult for Master Sun to ask, otherwise Old Man Sun may not know what to bury him, just take it as a long knowledge.

"You kid is so slippery, as treacherous as the old horseman, sure enough, there are teachers and disciples. ”

How could Murong Xiu's careful thinking escape Lord Sun's eyes, he wanted to take this opportunity to teach Murong Xiu another lesson, but unfortunately his treacherous plan failed to succeed, so he could only get back some lip service.

"Two groups of wolf cubs have one virtue, if they are changed to ordinary clothes, it is really difficult to distinguish, unless they say it themselves, otherwise they can only distinguish it from their words?"

"Speak?"

As soon as the words were spoken, Murong Xiu regretted it, since Lord Sun dared to say this, naturally it would not be so simple, this was waiting for him to enter the set.

"Hehe, forget it, it's really boring to quarrel with you little brat, and I don't have any sense of prevention. It doesn't hurt to tell you, this is not a conversation, you may find it ridiculous to listen to it, the Xiongnu will open their mouths wide when they pass on information to their people, and shout in the same voice as Poluo, while the Donghu people will roar low, and at the same time will use their hands to intermittently transmit the sound. ”

"Different roars mean different things, and we haven't been able to figure it all out so far, anyway, they're all aliens, and it's enough to know that. ”

When it comes to foreign races, Lord Sun doesn't hide it, he is very careful to tell Murong Xiu what he knows, but he looks like an elder.

After listening to Master Sun's explanation, not only did Murong Xiu stop holding back a smile as he wanted to speak, but everyone else around him also buried their heads and smiled bitterly, not only because of the way the Donghu and Xiongnu tribes transmitted information, but also because of this method of distinguishing the people of the two tribes.

"Okay, if you want to contribute to Zhongzhou, then hurry up and recover, the real battle has just begun, according to their previous style of acting, they will not retreat easily, the general attack is about to begin, damn poison master, it's really a headache!"

After speaking, Master Sun went to the other side along the city wall, helping the soldiers to sort out their armor for a while, and then looking at the weapons in the hands of the soldiers, and assigning everything that followed, with the attitude of a commander.

"Poisoner!"

Murong Xiu understood that the poison master in Lord Sun's mouth should be referring to those alien immortal cultivators he had met before, this profession could indeed dominate the battlefield, and with such a large-scale battle, a powerful poison master could almost influence the situation of the battle.

The poison of the poisoner is not so domineering, it is terrible when the poison occurs, the immortal cultivator must deal with it carefully when he is poisoned, then the effect on ordinary soldiers can be imagined, one loses his weapon, and those soldiers will become live targets on the battlefield.

And listening to what Lord Sun said, there should be a powerful poison master in the alien race, otherwise it wouldn't make him feel a headache even a master in the late stage of the Nine Heavens.

Bang!~

I don't know when a large number of dark clouds gathered in the sky above the gate of the wild goose, black and oppressive, and people panicked, only to see a silver snake falling from the dark clouds, followed by a dull thunder.
