Barr has been imprisoned for so long that he began to think when he had nothing to do in prison, and after a long time, his head turned out to be much brighter than before, and he also knew how to disperse his own power to reduce his pressure on the lord, the monarch and the minister had a tacit understanding with each other, and many words did not need to be pointed out, Yang Bing looked at Barr meaningfully, nodded, and began to explain other things.

"Although the teleportation array can't be used, there are still many passages on the third and fourth floors, and the defense of the forward fortress cannot be relaxed, at the entrance of the passage of the second and third floors, set up a sentry post, once a large-scale unknown army appears underground, immediately close the gate to the north on the second floor, and the bipedal Wyvern King who is blocking the road to the west, you have to find a way to eliminate it, I have already informed Baiyun City and Lvye City about this, and they will organize the air force to cooperate with you."

"No problem, the lord just rest assured." Barr patted his badge.

Now because the cave people in the north have also migrated over, so with the increase in the number of people, the outline of a city has gradually formed in the rear of the forward fortress, naturally in addition to the lack of recruiting buildings, in terms of scale has been infinitely close to Baiyun City, the cave people like this semi-underground living environment very much, so Yang Bing is not easy to force them, naturally Yang Bing's original plan to build a military fortress from the third underground to the second floor is also in the ground.

So I had no choice but to set up an observation post on the second floor, and installed a gate on the road leading to the north on the second floor, of course, once the gate was pulled down, it would be a large number of cave people, and it would not be possible to dig it in a short time.

After resting for a day at the advance fortress, Yang Bing took out ten minotaurs from Barr the next day, with the caravan that had been formed. Embark on a journey to the dungeon.

This time, the goods carried by Yang Bing consisted of grain, wine, cloth and weapons. Of course, this is just to hide people's eyes. The real bulk goods have been transferred to an underground warehouse by Yang Bing.

In charge of transporting the goods were two hundred cavemen, who drove a hundred wagons with Wormchula.

The appearance of the vermicules resembles giant earthworms that have eaten oxytocin, they can grow up to five meters long, but they are not aggressive, which naturally makes them the main source of animal power and meat for the underground system, their food is dirt and small amounts of food, and they are also the cheapest labor. If it weren't for the fact that the wormhills didn't go to the ground at all, Yang Bing would have already pulled them to work in the farmland in the north.

The caravan's escorts are fifty hell cavemen, ten phantom archers, ten minotaurs, a horror knight hero (Alex), and Yang Bing himself.

Such a lineup is enough to deal with small-scale battles, and the road from here to the third floor has been swept by Barr many times, so there is basically not much to be careful about, and after handing over the matter to Alex, who does not need to rest, Yang Bing consciously got into his caravan and went to sleep.

After walking like this for a few days, after reaching the third underground floor, the caravan was inevitably attacked many times.

The third basement floor is a space about the size of the barren grassland, and there are all kinds of underground creatures scattered everywhere. When Baal led his army down, he went straight to the teleportation array. This road is the only one that has been cleared by the army of the dungeon, so it is generally not too dangerous.

But now that the teleportation array can no longer be used, they must find a passage to the fourth underground floor, so naturally they can't follow the road that leads directly to the teleportation array, so after forking the road, along the way, the goods transported by the caravan are like a piece of fresh meat with juice, attracting waves of attackers like flies.

"It's been half a week since you walked on the third floor, and you haven't found a suitable entrance?" Yang Bing slapped down some of the feathers that were stuck to his body and said lightly, just because of the bumpy road, a jar of wine fell from the truck, naturally this wine fragrance attracted the attack of a group of harpies, but fortunately, the phantom shooter equipped with night vision devices quickly shot them down, so there was no loss.

"My lord, there are not many channels that can allow our goods to pass through, and I have already sent a team to expand the search area." The Minotaur replied humbly.

Most of these passages from the third floor to the fourth floor were dug by the cave people who moved around, not a large cave man tribe, and they would not open too large passages, which naturally blocked the army of the dungeon from entering the upper layer, but it was also not so easy for people like Yang Bing to go down.

Yang Bing naturally knew that he couldn't just find a hole and drill into it, so he waved his hand and called Dawn to command the team to move on, but just when Yang Bing wanted to continue to return to his car, Jason, the head of the Phantom Shooter, walked up quickly.

"My lord, we caught a captive, and she said she knew the passage through which vehicles could be allowed." Jason saw Yang Bing and immediately saluted and reported.

"Oh! It's okay, let's bring her here. Yang Bing stopped and said lightly.

After just a while, Jason walked over with a harpy, and the harpy was only shot in the wing, which was naturally a deliberate attempt by the phantom shooter.

For the harpy, Yang Bing still has a lot of feelings. I think when he was poor and white, it was the dedication of a harpy banshee that created the current Yang Bing's family business, unfortunately the harpy banshee has all been killed, if they are still alive, in the system with Yang Bing as the leader, they should have a status that is not inferior to the thieves.

The harpy originally wanted to steal something with her companions and run away, but she didn't expect that the phantom shooter equipped with a night vision device would find them in advance, and none of her companions could run back, and she was also deliberately shot into the wings by the phantom shooter who released the water and became a prisoner.

"Do you know where the large passage is?" Yang Bing motioned for Jason to put the Harpy Banshee down, and said in a soft tone as much as possible, obviously this body size is not much different from the dwarf, and in Yang Bing's eyes, the Harpy Banshee who is a little guy is not lightly frightened, and it can be seen from the fact that the feathers on his body are so nervous that they stand up.

"Just in our tribe, a few days ago, there was an adventurous party that went in, and they left us some delicious food and hired a lot of our companions." Glancing at Yang Bing in fear, the harpy said in a low voice.

The passage that can be called for the cart to pass through, this is undoubtedly the best news that Yang Bing has heard these days, and he casually used a healing magic to heal the injury of the Harpy, and then naturally asked her to take the entire caravan to turn around and go to the Harpy tribe where she is located.

Fortunately, this little guy is relatively honest, and he didn't play any tricks, and soon Yang Bing and the others saw the tribe where the little guy was, originally the harpy tribe was not far from where the incident occurred, it was located on an underground cliff, and in a stone crevice in the middle of the cliff was the nest of the harpies, hundreds of harpys lived in it, and saw a team coming from afar, these harpies even screamed, rose from the cliff, and hovered in the air for a while, Converged into a huge cloud and pounced like a caravan.

Alex, who had been at the front of the caravan, immediately urged the horse to meet him when he saw this, and when he was about to collide with the Harpy herd, the skeleton horse under its crotch suddenly stood up, and Alex raised his sword high, and the red light in his eyes was as bright as red flame.

The coercion from the higher races swept away into the air in front of it, and the harpy banshees, who had already swooped over, avoided and scattered to one side, and when they flew back into the air, they just kept screaming, but they didn't dare to lower their altitude again.

Yang Bing looked at the situation outside and said with a faint smile: "The terrifying knight is strong, and his appearance is good, he is really a first-class bodyguard and thug, and he can strengthen his appearance if he takes it out." ”

After roughly calculating the number of this group of harpy banshees, Yang Bing immediately had no intention of coming out, and he also knew more clearly what kind of combat power the harpy banshees had, and they also had such an advantage of being able to fly, but there were ten phantom archers in the caravan, and under the protection of the minotaurs, the harpy banshees could not get close at all.

Just when Yang Bing was ready to watch the play. (To be continued......)
