After entering the tunnel, I found that it was much better than I had imagined, at least more spacious than what I saw from the outside. The candle on the miner's helmet showed its true magic at this time, and the candle flame two fingers thick at this moment illuminated the surrounding tunnel space dozens of meters long. Even the earthworms at their feet struggling to move forward can be seen clearly.

As soon as I entered the tunnel, the miners were already digging. He swung his shovel, and the large blocks of dirt and rock were quickly peeled off like the skin of a dilapidated house, and then vanished into the world before falling to the ground. With this astonishing efficiency, we had not even taken ten steps before the miners had dug an underground tunnel in front of us, which was almost twenty meters long and two meters wide. Even on the modern earth, I am afraid that no engineering team can do it, and the drilling rig of the mine must be nothing more than that.

"My lord, keep up, we'll be out in a moment."

The miners beckoned us from a distance, and I followed the two illusionists with me, for fear of being left behind, in the darkness of instability.

The miner lived up to his legendary name, he was so fast that even I, a half-combat master, had to speed up my pace and keep up with the bright light of the fire as I navigated the tunnel, which had reached fifteen meters underground. The surrounding air is very turbid, and you can't feel the so-called "earthy smell" at all, which makes people feel out of breath. But I don't think it's going to be a good idea, because the miners are working too efficiently, and there is not enough air for three people to breathe in many places. I'm trying to use wind elemental magic here, but the sense is weak, and it's a waste of time to use.

But the two illusionists next to me were in a lot more condition, and when I asked them why, they told me a lot of vague terms related to magic, which I didn't understand, but I really envied them, at least they were much more optimistic than I was.

We followed the miners for a long time, because it is not easy to estimate the time and route underground, so it is difficult for me to estimate the distance and general direction, I can only say that this fortress is really huge, even if the curve is extended, the distance we are walking now is equivalent to half a mantas, and the White Oak Fortress does not have this scale. This kind of military fortress with a huge scale and super defense capability is terrifying when I think about it. If we had traveled here during the most prosperous period of Subic, I am afraid that it would be difficult for us to rise, and the strength of the kingdom at that time would be difficult to confront even now.

"The magic sense here is very strong, ten meters underground are within the monitoring range, and the rock layer underground is also very hard, and these things, I'm afraid they have found out that we have escaped."

The miner stopped suddenly, and a blue crystal the size of soap appeared in his hand, the crystal looked dull, but there were dense inscriptions on it, and some gemstone decorations that obviously did not belong to this crystal, it could not be artificial.

"This was buried here before, and there is a magic circle around it, but it has been destroyed by me, and there must be this kind of thing in other places underground, a large-scale underground confinement magic circle."

The miner handed me the crystal, and then I decisively closed the crystal, which had lost its ability to detect and imprison, and waved my hand. 、

"Let's hurry up and go as far as possible!"

The miners are digging again, and the speed is noticeably faster. We walked along this tunnel for a long time, and finally began to make our way up, and it seemed that we were out of the range of magical surveillance and far from the fortress of Sakturi. However, the miner also found a not-so-good news, that is, there are some special energy fluctuations in the tunnel he dug out, and he has collapsed all the tunnels behind us, but the kingdom can still know how to escape.

The miner's shovel finally pierced through the ground, and the sun shone down on us once again. After a few terrible days in prison, I finally felt the warmth of the sunshine of this world again, and it was a good feeling. Of course, if you ignore the two Kingdom patrols who fell into the pit and the patrol next to the exit....

The digging miners jumped out directly, and with a wave of the shovel, several kingdom soldiers flew out directly, the armor on their bodies was shattered, and before the other soldiers had time to dodge, the ground under their feet was dented, and they fell into the pit and were pierced by the sharp rocks in the pit.

The miners grabbed my hand and dragged me up with great ease, and the two illusionists, who had good physical strength, quickly followed. However, at this time, we realized that we had miscalculated, and this was actually the garrison of a kingdom patrol, and nearby, there was a group of kingdom cavalry.

However, after a shovel blow from the miners, the six Kingdom cavalry were swallowed up by the soil and rock, and crushed by the powerful pressure.

The illusionist and I rode the frightened horses and left with the miners, but fortunately my riding skills were good, and my strength was still there, otherwise I would not have been able to control this frightened fast horse.

I immediately saw the fortress that had trapped me for days, and although I was mentally prepared, I was shocked.

What a magnificent castle, what a strong and wide wall, black and white formed the main color of the castle, and the emerald green giant magic crystal was inlaid on the spires around the castle, forming an impenetrable magical barrier. The top of the castle plunged into the sky like thunder and lightning, and the elemental magic continued to rise and fall around the fortress like a tidal wave, and from time to time it spewed out a strange lightning bolt that landed on the nearby ground, setting off a huge wave in the magical realm invisible to mortals.

My army had taken the White Oak Fortress and breached the defenses of Mantas, and I had thought that the Kingdom of Subic was no longer a city that our three hosts could not defeat together, but before this magnificent fortress that had drained the treasury of the Kingdom of Subic at its peak, I felt a deep sense of powerlessness.

Perhaps, even Wang Shengzhe's flying dragon will not be able to break through the city's defenses, and only the tactics of digging miners can cause trouble here from the inside.

However, I was also worried about how powerful the Northern Empire was that could barely be stopped by building such a magnificent fortress.

What can we do to make us, the smugglers from another world who have been exposed their identities, persevere, develop, and achieve our careers under the pressure of these giants.......
