All three of them were amazed when they saw the buildings of other races other than humans for the first time.

At the mouth of the valley, a fortress is built by relying on natural hazards, the fortress is dozens of meters high, all made of large stone piles, more carved by the mountain itself, although it is not as delicate as human architecture, but it can also be called a ghostly workmanship.

On the walls of the fortress, large crossbow guns and stone throwing secrets were densely arranged, looking at the crossbow arrows as thick as a small tree, Ye Chen couldn't help but wipe his sweat, this kind of defense was really hard to imagine how those people broke in.

Even if he is a powerhouse in the Martial King Realm, if he is accidentally shot by that large crossbow arrow, he is afraid that he will fall on the spot.

A huge gap had been torn out in the middle of the fortress, and the orc soldiers standing in the fortress were tense, and needless to say, they could guess that it was obviously Gonggong Qin's group of people who killed it.

"Boss, what should I do?" He Yang frowned as he looked at the highly-alert soldiers below the fortress.

"Use the concealment technique, let's take advantage of the chaos to blend in through that gap."

The three people with the art of concealment did not dare to breathe, and quietly approached the fortress wall, where an orc was directing the restoration of the fortress.

The three of them passed through the city wall under the noses of the orc soldiers, and just as Ye Chen breathed a sigh of relief, an orc laborer suddenly stared at his group.

Ye Chen was stunned for a moment, and before he could react, the orc walked straight over.

He Yang put his hand on the knife, ready to improvise.

But the orc walked to the ground beside him, picked up a piece of jade from the ground, stuffed it into his clothes with joy, and walked back to work.

Ye Chen let out a long breath and motioned to the other two to continue walking.

Perhaps because Gonggong Qin and his group had broken in before, after passing through the fortress, there were not many soldiers on duty inside, and there were many orcs moving towards the inside of the fortress.

This made a few people mix in so easily, in the interior of this orc city wall, it can be said that there is a cave, I thought it was just a valley, but this fortress is surprisingly large, in terms of area, even Chang'an City may not be as big as an orc fortress.

"I don't know how many years this orc has been breeding here in a low-key manner, and it has such a city scale......" Ye Chen couldn't help but say in his heart.

"Be careful, there's a wall ahead." He Zheng Tianzun reminded.

Ye Chen raised his head, this city wall didn't seem to have suffered too much damage compared to the outer wall just now, and the garrison force on it was more than several times that of the outer wall, and the orc soldiers were constantly patrolling with sharp axes or spears.

Just as the three of them were about to mix up again, a low roar of a frost wolf came from the side.

"Woo......"

Ye Chen turned his head and found that next to him were several shacks where frost wolves were raised, and at this time, one of the frost wolves was staring at the three of them and making a whimpering sound.

In the next second, the frost wolf accelerated violently and pounced on the three of them!

Ye Chen dodged, and immediately showed his original form, and hit the frost wolf in the head with a heavy punch, and the frost wolf screamed and passed out.

The orcs immediately spotted Ye Chen, an alarm sounded, Ye Chen glanced at the two who had not yet been exposed, and one rushed towards the other side of the city wall.

"There are enemies! Crossbowmen prepare, release arrows! ”

The orc soldier who heard the order quickly returned to his post and pulled up his crossbow arrow to aim at Ye Chen.

Ye Chen's brain was buzzing at the moment, and he didn't care that there were still a few frost wolves behind him catching up with him, one of them didn't stop, and he was shot by the crossbow arrow, and his body would immediately turn into a rock sugar gourd.

"Aim and launch, pin this human to the ground!" An Overseer shouted as he watched Ye Chen's fleeing figure. "Really, who is the orc tribe who comes and goes whenever they want?"

The words fell, in front of the crossbow arrows in a group of three, one archer took aim, and the other two orcs were responsible for drawing the bow and loading the arrows, and in an instant, the crossbow arrows in the air were densely packed in the direction that Ye Chen rushed out.

But the figure was like an eye on the back of its head, and it was always able to dodge one crossbow arrow after another that was about to hit.

"Damn it, keep firing the arrows! Whoever can shoot him will be rewarded with a frostwolf mount! The Overseer shouted, brandishing his battle axe, "Let humanity know that we orcs are not easy to bully!" ”

The Overseer looked at Ye Chen's back with a cold face, he had already let a group of humans break in at night when he was still asleep, and now the person in front of him was obviously not strong, but he slipped in under his nose, which made him feel annoyed.

The crossbow arrow was another volley, dense enough to shoot Ye Chen into a hedgehog, and all the orcs stared at it, but it was expected that the scene where he was shot into a hedgehog did not appear, only to see this figure jump high, soar into the sky, and then disappear from view.

The Overseer's face turned grim, "Look what, a bunch of rice buckets, keep patrolling!" Heighten your vigilance! ”

Ye Chen's heart was pounding, fortunately, the ancestor made a move, otherwise he would really become a hedgehog now.

After passing through the two city walls, Ye Chen didn't dare to stop for a moment, for fear that the orcs behind him would catch up and continue to fly towards the valley.

"Master, do you want to go back and wait for my two friends?" Ye Chen said with some concern.

"The strength of the Martial King Realm is more than enough to deal with those orcs at the gate, so there is no need to worry."

…………

After leaving the fortress city, Ye Chen had been on the road for several hours in a row, but he still didn't see any trace of the city, if it weren't for the occasional sight of some orc soldiers patrolling in the valley, he even wondered if he had taken the wrong road.

Finally, before the sun set, Ye Chen walked out of this valley.

The scene that came into his eyes was not only Ye Chen, but even He Zheng Tianzun was shocked.

Compared to the next door outside, this place is simply another world, and it has to be said that there is a reason why orcs have been able to inhabit again for thousands of years without perishing.

At the end of the valley is a plain, although it is wrapped in the valley, the area is not particularly vast, but the rivers and mountains, green grass, full of green, compared with the Gobi outside the mountain, it is like a world away, and the main city of the orcs is in the center of this oasis.

Ye Chen glanced at it and immediately found the problem.

No wonder there is no water outside, these orcs have blocked the river channel that flows downstream from the mountains for their own survival, and built a dam, and it is strange that there can be water downstream.

And looking at the amount of water stored in the embankment, it is by no means a day or two of the amount of work, I am afraid that I don't know how many years the water flow has been cut off.

It stands to reason that this kind of place must be heavily guarded, but at this time, all the orcs seem to have returned to the city to deal with the uninvited guests of Gonggong Qin, and there is no guard in front of this embankment.

This made Ye Chen cheaper, he walked to the embankment, took out homemade explosives from the Qiankun bag, and stuffed it evenly into the weak stress points of the embankment.

"What is this?" He Zhengtianzun, who had never seen explosives, asked with some curiosity.

"Back to Shizu, this thing is called explosives, you shouldn't have invented it in that year, this is what I did when I was alchemy, and it has the power to open mountains and split stones."

"Dynamite? Can medicine also open mountains and split rocks? He Zhengtianzun was a little puzzled.

"Master, you just look at it!"

The current explanation and Zhengtianzun can't understand it, but practice still brings true knowledge.

After Ye Chen stuffed all the explosives, he lit the fuse and quickly evacuated, "Master, you have a good look!" ”

Boom ——!

With the sound of a huge explosion, the embankment that the orcs had built for an unknown number of years collapsed in an instant, and Zheng Tianzun was shocked to see it, how powerful the medicine was?

Ye Chen just wanted to be happy, but found that he had underestimated the amount of water stored in this embankment.

The levee was destroyed, and the water inside swept up in huge waves, half of which rushed into the valley, down the dry river, and the other half poured directly into the direction of the orc's main city.

…………

Outside the orc main city, several figures in the sky slowly landed, it was Gonggong Qin and his party.

"You humans have invaded my orc territory and injured my people, it's better to have an explanation, otherwise no matter how strong you are, I will let you know that the old dog also has a few teeth......," said an extraorc who stood at the gate of the city and said loudly.

The orc's name was Grom, who was now the chief of the orc tribe and Duron's father.

"We are here, not for anything else, but I have heard that the demon clan wants to be friendly with you recently, so it is necessary to talk about it......" Gonggong Qin walked out of the crowd and at the same time lit up Du Long, who was unconscious behind him.

When Grom saw that his son had fallen into the hands of the other party, and his life and death were uncertain, his face immediately turned cold.

"What have you done to my son, despicable human!"

"It's okay, he's just tired of helping us lead the way, rest for a while......" Father-in-law Qin said, and gently patted Du Long on the shoulder twice with his hand, and the latter slowly woke up.

"Thank you for leading the way, I won't lie to you, we're just here to talk, and help you orcs solve some problems you can't solve." Gonggong Qin looked at Du Long, who had woken up, and said.

Duron gradually regained his senses, and when he saw that he was already in front of the house, he immediately understood what was going on.
