When the army of the Black Ice Tribe advanced rapidly, the spiritual power cannon on Zhao Chun's side finally sounded, but they only had nineteen cannons, and there were not many spirit stones that could be used to drive. The most strange thing is that these spiritual cannons are not lined up together, but there is one every forty or fifty meters, and the only thing that makes people feel that they still have merit is that it fires relatively fast, and it can shoot two shells in a minute.

Although these spiritual cannons caused some trouble to the charge of the Black Ice Tribe army, and also caused some casualties, in just ten minutes, they caused thousands of casualties to the Black Ice Tribe army, but their number was too small, and the spirit stone energy they stored could only support them to fire so many cannonballs, and they were quickly counterattacked and suppressed by the Black Ice Tribe artillery force.

The shells of the Black Ice Tribe army once again fell on the place where Zhao Chun's troops set up the spiritual power cannon as if they didn't want money, and some of the spiritual power cannons and operators who had not had time to transfer were lost in this way.

At the same time, the Black Ice Tribe army that was charging forward quickly, its vanguard had reached the trap dug by Xiaolu and the others, and the flying soldiers in the air were fine, but the cavalry that charged quickly was not so lucky, and even the men and horses fell into the trap one after another, and then were killed by the swords, spears and ambushed soldiers hidden in the trap.

Although the cavalry behind knew that there was a trap in front, due to the speed of the horse beast, it was not something that could be stopped in a hurry at all, and the cavalry behind was constantly coming, so it could be seen that the tens of thousands of cavalry charging in front of the Black Ice Tribe fell into chaos.

But the commander of the Black Ice Tribe is not a vegetarian, after a short period of confusion, they immediately let the pilots turn around and strike at the enemies in the traps and tunnels, and after sorting out the cavalry team behind, these cavalrymen also used spiritual arrows to shoot frantically into the traps and tunnels, and even had **, machine guns, mortars and other thermal weapons to assist.

Fortunately, the tunnels dug by Xiaolu and his people are criss-crossed, extending from one place to another I don't know how long, as if this radius of several square kilometers is covered with tunnels like spider webs, if one battle is unfavorable, you can immediately withdraw in other directions, or rush to reinforcements from other directions.

Because it was night, the light in the tunnel was very dim, so it was difficult for the Black Ice Tribe, whether it was cavalry or flying soldiers, to see if there were people in the tunnel, or how many people there were, they could only shoot blindly into the tunnel.

And Xiaolu's soldiers are also more flexible in combat, ambushing in some tunnels, shooting spiritual arrows at the right time to annihilate small groups of enemies, and when the enemy's large army reacts and concentrates their firepower to shoot in this direction, they move to another direction.

The commander of the Black Ice Tribe naturally also thought of a lot of ways, such as putting fuel into the tunnel, sending a large number of infantry into the tunnel, etc., but because they fought from a long distance, they did not carry much fuel, and they did not prepare in advance, so the effect of fuel was not great, and the ground here was covered with snow, and it would not take long to extinguish the fire......

As for sending a large number of infantry into the tunnel, it had some effect, they fought fiercely with the soldiers of Zhao Chun's troops in the tunnel, but because the tunnels were narrow, many of them could only allow two people to pass side by side, so they advanced very slowly, often less than a hundred meters in ten minutes, and some were even recaptured by the soldiers of Zhao Chun's troops, but in this way, the pressure on Zhao Chun's troops also increased greatly, and Xiaolu had to ask Laura to transfer the flying troops hiding in the Black Forest to support.

Because there are flying soldiers to deal with the enemy's flying soldiers, the threat from the air can be greatly reduced, but there are only more than a thousand flying soldiers on Zhao Chun's side, and they usually have something to do, so they are easily not allowed to go to the battlefield, and now they are pulled out to face the enemy at once, and it is facing the enemy who is several times their own flying soldiers, which is really not a fair battle.

Despite this, the pilots did not flinch in the slightest, shooting frantically while rushing towards the enemy quickly, because they did not have many spiritual arrows, and if they were to shoot each other in a formation as usual, they would not last long. Only by rushing into the enemy's formation, after the spiritual arrows are shot, they rely on swords and spears, and when the swords and spears are gone, they rely on their bodies and flying beasts to crash into them entirely, even if they die, they will fall from the air with an enemy in their arms and die!

As soon as they saw them rushing towards them, they all dodged away from a plague like a plague, and some of them even fled directly, but after the prison army behind them killed a few flying soldiers who tried to escape and retreat, they barely suppressed the signs of collapse.

However, although the pilots on Zhao Chun's side were not afraid of death, the gap in terms of numbers and other aspects was too great, so after an hour, all the more than 1,000 pilots died heroically, and none of them survived. However, they also inflicted more than 3,000 casualties on the Black Ice Tribe's pilots, greatly reducing the combat effectiveness of this originally 5,000-strong flying force, and it was no longer possible to provide strong support to their infantry fighting in the tunnels as they did at the beginning.

The same scene was also played out in the infantry units of Xiaolu and Shenju, because the Black Ice Tribe was surrounded and attacked on three sides, and only the Black Forest direction had no enemy for the time being, so they could only retreat in the direction of the Black Forest while fighting, and now two-thirds of their tunnels had fallen into the hands of the enemy, and they could only fight with the enemy in the remaining one-third of the tunnels.

Laura retreated to the edge of the Black Forest with Xiaolu, Shen Ju and others to discuss.

"Zhao Chun hasn't come back yet, it's not a way to go on like this, there are too many enemies, they can't kill them all, and they don't know how to get the hot weapons outside us, which has caused us a lot of casualties. Laura said with some frustration that Zhao Chun was not here, which made her feel like she had lost her backbone.

"Why don't we retreat into the Black Forest? The Black Ice Tribe's army probably won't chase after it. Xiaolu said with a frown, his hands were wrapped in bloody bandages, and he was slightly injured by the fierce battle just now.

"No, I can't. Shen Ju objected, he was also covered with blood, but it was not his own, but the enemy's, he was enjoying killing just now, and he was forcibly called, and he was very unhappy. "As soon as we retreat, our morale is lost, how can we defeat the Black Ice Tribe in the future? Will we be like a lost dog in the future, chased and beaten by others? I can't do such a thing. If you want to kill, kill it!"

Laura also said: "If we retreat now, there are indeed many disadvantages for us, such as we don't know the danger in the Black Forest, and we don't know if the army of the Black Ice Tribe will chase after us......

Although they are three or four times as numerous as ours and their weapons are advanced, as long as we carry forward the spirit of not being afraid of sacrifice, it is not certain who will be killed. Xiaolu clenched his fists and said, since you don't have a choice, let's fight, anyway, people always have to die, and if you can fight for freedom and faith, even if it's worth dying.

The battle was still raging, and Laura's 5,000 backups had been dispatched, and people on both sides were constantly falling, shouting for killing, screaming, gunshots, and weapons clashing...... The sounds are intertwined, like a miserable purgatory of the apocalyptic.
