Before reaching the crystal mine, there was also a barrier city blocking Xu Yun's direction.

Looking at the city in the distance, which was surrounded by a city wall more than ten meters high, Xu Yun felt that things were a little tricky.

Because Rebecca only told him that there was a barrier city in front of the crystal mine, he thought that it would be at most a third-order city, a city of this level, for him, a lord with a large number of long-range troops and nine units of seventh-order angels, it was just a matter of breaking through it, he had broken a lot of third-order dungeons, and he had also won two fourth-order dungeons, so there was no reason why he couldn't take a third-order barrier city.

But after seeing the barrier city in front of him, Xu Yun knew that he was wrong, because the barrier city in front of him not only had the third-order city wall of the third-order city, but also in front of the city wall, it was also covered with a large number of thorns, and these thorns several meters high seemed to be gently wriggling like living creatures, giving people the illusion that they would pounce on him in the next second.

These are not the most important, the most important thing is that the massive third-order wood elf troops crowded with the city wall, and many elves full of wisdom are pointing at this side, the number of wood elves crowded on the city wall alone is more than 10,000, and I don't know how many wood elves the other party has not taken out.

There are also ten giant crossbows placed on the city wall, these are like murder weapons that have been expanded countless times by the second-order archer weapons of the castle camp, and there is a steel arrow with an egg thickness of two meters and a length of two meters, which exudes a chilling cold light, just looking at it makes people shudder, if you are really shot by this weapon, it must feel very 'good'.

The woods within 500 meters of the city don't know whether intentionally or unintentionally there is not a single tree left, as if it has been emptied.

Xu Yuncai and Joan of Arc stepped into the open space under the protection of the long-range troops, and a strong and incomparably strong sense of crisis came out of nowhere, and surged wildly in the bottom of his heart.

Xu Yun had long been convinced of his instinct that had saved him many times in the game, so his first reaction was to pounce on Joan of Arc on the side, and hug her and quickly roll to the side.

"Poof!"

"Poof!"

"Poof!"

……

The sound of sharp weapons piercing flesh and blood continued to sound.

"Bump!"

The sound of the air as if it was being exploded reached the ears of Xu Yun, who was crawling on the ground with Joan of Arc.

When everything calmed down, Xu Yun, who had rolled away from his previous position, knew what had just happened.

Ten steel arrows taller than a human being, like an invincible Thor spear, shot into the ground after cutting a bloody path several meters long from the place where he had just stood.

Looking at the arrow body that only one-third of the ground was exposed, as well as the incomparably intricate magic patterns on the arrow body, Xu Yun believed that if it weren't for the angle problem, these giant arrows might have shot directly through his troop formation.

"Retreat!!" , quickly stood up from the ground, and before checking how many troops he had lost in this attack, Xu Yun hurriedly shouted to Joan of Arc who had just stood up, it was his intuition that saved his life and Joan of Arc's life, if this attack happened again, he was not sure that he would dodge it again, who knows if intuition can always play a role.

Fortunately, what reassured Xu Yun was that after the giant crossbow arrow attacked this time, the other party didn't seem to have any intention of attacking again.

"Is it attack speed? , or is it something else? ”。

Retreating into the forest for a few tens of meters, allowing the troops to hide behind the trees to avoid being attacked again by the opponent's giant crossbow, Xu Yun looked at the barrier city in front of him, he was guessing the reason why the other party didn't launch a second wave of attacks, if the other party just launched a second round of attacks, he would really die once.

"My lord, we lost 33 units of Sun Archers and 5 units of Monks, all blame me for not noticing that the other party would have enchanted arrows in time, and the range of ordinary bed crossbows is only 300 meters", Joan of Arc reported the loss to Xu Yun just now.

If it weren't for the firing angle of the ten bed crossbows on the city wall, this loss might have been magnified many times, and she blamed herself for not realizing in time that the other party was on the bed crossbow with enchanted crossbow arrows.

"It's not your fault, if those bed crossbows were only 300 meters under normal circumstances, no one would have thought that they could increase their range for such a long time", Xu Yun comforted Joan of Arc, this situation can't be blamed on Joan of Arc at all, from such a distance, who knows that the opponent's arrows are enchanted.

In fact, hearing the number of troops lost, Xu Yun also regretted a little, why didn't he release the Shengyan guards in the troop card in advance just now, otherwise how could he encounter such a danger.

"If you want to capture this walled city, do you have to find a way to deal with these giant crossbows first?" Looking at the barrier city in the distance, Xu Yun felt a little headache.

Because he really doesn't have a very good way, he can quickly capture this city that is guarded by all long-range troops, like this situation, generally speaking, it is the best choice to use the flying class to directly destroy the opponent's bed crossbow, but the opponent's city wall alone is crowded with more than 10,000 third-order wood elves, not to mention how many wood elves are still hidden in the city, and the number of flying troops to destroy the giant crossbow is less than to deliver food.

The number of flying troops under Xu Yun's current command, even if you count the Angel Squad and the Flying Dragon Emperor, is only less than five hundred units, and this number of flying troops alone has no possibility of breaking through the opponent's long-range firepower to destroy those giant crossbows.

Knowing that there were more than a dozen high-level crystal mines waiting for him to occupy in front of him, but he was blocked by the enemy here, Xu Yun felt very depressed.

"Why did the other party open the door?" Just when Xu Yun was thinking about whether to retreat first, lest the troops be damaged too much and the players who would not be able to stop the Infinite Serpent, he heard Joan of Arc remind the wall and hurriedly looked over.

I saw the city gate open in the distance, and a male elf on a white war horse was coming this way, holding a white flag in his hand.

"My lord, the other party is asking for negotiation!" , Joan of Arc helped Xu Yun popularize science in time.

Nodding, Xu Yun didn't speak, even if Joan of Arc didn't remind him, he guessed what the other party wanted to do.

The elf riding on the war horse slowly rode forward, as if he didn't want to cause a misunderstanding to Xu Yun, and when he walked to the edge of the clearing, only a few dozen meters away from Xu Yun, he stopped the pace of the war horse under the seat.

"Adventurer! , you adventurers are not welcome in the Green Wind Plane, please leave this plane, or you will meet the punishment of our dragon god! The male elf shouted at Xu Yun.

Curiously glanced at the elf riding on the war horse, Xu Yun had long heard that all the NPCs in the evolution were very intelligent, although he had two living examples of Joan of Arc and Celal, but he had always been either fighting in the game or farming monsters on a single machine, and rarely had time to contact these ordinary NPCs, and now it seems that the intelligence of these ordinary NPCs is indeed very high.

"The entrance to this plane has been mastered by me, you can only choose the way to surrender to me, and I will not accept any negotiations other than that!" Of course, Xu Yun couldn't just be threatened casually like this, and then leave with his tail between his legs, even if he couldn't capture the other party's city for the time being, of course he couldn't admit it, and the most important thing was that the entrance to this plane fragment was in his hands.

Therefore, Xu Yunjin can attack and retreat, even if he can't take this barrier city for a while, but after his strength grows, he will be able to take this barrier city sooner or later, and then occupy those crystal mines, although the player's strength is lower than that of NPCs, but in terms of growth speed, it is definitely beyond the reach of NPCs.

This is where Xu Yun's confidence lies, he firmly believes that he will have the strength to win the other party sooner or later, so he did not give the other party a second choice at all.

"Arrogant adventurer, you will regret your arrogance!"

This elf NPC also seemed to hear the firmness in Xu Yun's words, and knew that the negotiation was broken, so he put down his cruel words and turned around and left.

Hearing that the other party was disrespectful to her lord, Rebecca instantly spread her wings, ready to go up and kill the other party, even if she couldn't kill it, she would teach the other party a lesson, but she was stopped by Xu Yun

"Forget it, Rebecca!"

Xu Yun waved his hand to stop Rebecca who was about to fly, and the other party was right, he only gave them a choice to surrender to him, which was indeed very arrogant in their eyes, but how could they know the growth rate of the player.

Hatefully looking at the elf who was riding back on her horse, Rebecca retracted her wings.

When the elf returned to the city, there were no troops in the city, but there was an eerie silence.

"Is it just a cruel thing?" , Seeing that more than ten minutes have passed, there has been no movement in the barrier city in the distance, which makes Xu Yun, who commanded Joan of Arc and the troops to be on standby, and is ready to fight a wild encounter with the other party, feels that things are a little strange.

But this thought only rose from Xu Yun's mind, and there was an astonishing movement in the city in the distance.

A huge pillar of green light rose from the city, and the pillar of light rose to a height of 100 meters before continuing to rise.

"Magic Attack! , not like it? Staring at the green pillar of light in the distance that seemed to connect heaven and earth, Xu Yun didn't feel any danger, and looked at Joan of Arc and Rebecca next to him without any movement, as if he didn't feel danger, and he couldn't figure out why the other party wanted to release this pillar of light at the moment.

But the other party prepared for such a long time to release this pillar of light, of course, it couldn't be a joke with Xu Yun.

A few seconds later.

"Boom!!" , like an earthquake, sounded from a hundred meters behind the walled city.

A breathtaking sense of fear rose from Xu Yun's heart, his body seemed to be under tremendous pressure, and even moving was a luxury, and out of the corner of his eye, he saw that among the Sun Shooter troops on his side, there were also many troops like himself, and this kind of body was like himself.
