Watching the scattered cultivators leave one by one, General Ke did not stop him, and only after no one in the scattered cultivator team left did he speak again: "Let's go!"

At the sound of the order, the army marched out, and the 100,000 troops marched towards the interior of a fortress within the Great Wall.

"How did you get into the fortress?" Seeing this, the scattered cultivators all had doubts in their hearts, and Su Yu and the others also raised their eyebrows, but when a few people walked into the inside of this fortress, they found that this fortress was different from other fortress structures, it was empty, and the 100,000 troops who came in before them disappeared.

Although this fortress is large, although it can accommodate more than 100,000 or 200,000 people, it is a little surprising that when an army of 100,000 enters it, it is like a drop of water into the sea and disappears.

The scattered cultivators had doubts in their hearts, where did the 100,000 army go?

"Come with me, don't walk around, don't talk nonsense when you see anything for a while, or don't blame me for not reminding me. A man who looked like an officer appeared and shouted loudly, not giving the crowd a chance to speak, but to go first, towards an open door.

After passing through the gate, everyone realized that there was a passage behind the gate, which was diagonally downward, because the angle of the passage could not be seen how deep the passage was.

Just walked diagonally down for more than half an hour, and everyone didn't continue to go down, Su Yu silently calculated, this passage was at least a few hundred meters deep underground.

Su Yu and Lao Wu glanced at each other, they were all secretly speechless, they usually dig a passage tens of meters deep is already the limit, this passage is hundreds of meters deep, Su Yu and the others can be regarded as strong people who have seen digging tunnels.

Sure enough, there are strong players in this kind of thing.

The amount of work to dig this passage at a depth of several hundred meters is too large, and it cannot be dug out in a day or two, and a lot of manpower and material resources must be invested.

However, this is not the place that makes Su Yu and the others astonished, what makes Su Yu and the others amazed is that there is such a passage in the land of the Ansan realm, thinking back to the road they have walked before, the direction of this passage is to the outside of the Great Wall.

Su Yu now understood what method General Nak used to break through the blockade of the alien coalition army, transport the army outside the Great Wall, and carry out a sneak attack on the rear of the alien coalition army.

Obviously, the other party dug such a passage early, in order to be today.

However, what surprised Su Yu even more was that General Nake was really bold enough - this passage was able to lead beyond the Great Wall and transport the army of the Terran Race beyond the Great Wall.

Conversely, aliens can use this passage to enter the Great Wall, which is extremely dangerous.

Or is General Nak confident that the alien race will not be able to discover this passage, or will the alien race not be able to enter the Great Wall through this passage even if the alien race discovers this passage?

"Su Yu, take a closer look at the walls on both sides of the passage!" At this time, the fat man struck Su Yu with his elbow and said in a low voice.

Hearing this, Su Yu took a closer look at this passage, the walls on both sides were very smooth, but if you looked closely, you could find that there was fluorescence flowing, and your eyesight was not good, so if you didn't look carefully, you wouldn't be able to find it at all.

"The walls are carved with source arrays, there are reinforced source arrays, but there are more blasting source arrays, if they are detonated, they can directly blow up this passage and bury everyone, that General Ke is really ruthless, tsk~" The fat man continued.

Su Yu's heart was also slightly cold when he heard this, knowing that the blasting source array was the back hand of General Nake, even if this passage was discovered by the alien race, he could immediately destroy this passage.

Completely destroy the passage and not give the enemy a chance to take advantage of it.

This passage is hundreds of meters deep underground, once it collapses, the soil and rocks hundreds of meters thick above it are pressed down, the weight is extremely terrifying, not to mention the lower three grades, the middle three grades, it may be that even the high-grade strong people can't withstand that kind of power.

At least the seventh-rank powerhouse is impossible to resist the weight of hundreds of meters of earth and stone.

It took nearly two hours for the people to walk underground, and then they returned to the surface, but they did not immediately see the brilliant colors of the sky.

The underground passage is a total of 200 miles long, leading directly to the rear of the alien coalition army, and the exit is also very particular, it is actually in a big mountain, the inside of this big mountain is hollow, all the traces of excavation, it is artificially hollowed out.

More than 100,000 people gathered in the belly of this mountain, and it didn't seem crowded at all, and it even felt empty.

It was not dark in the belly of the mountain, and the source energy lamps were lit, and piles of bonfires were lit, illuminating the belly of the mountain.

The army that arrived here first has already started to light a fire to cook and make pre-war repairs, and this meal may be the last meal for everyone here, or it is possible that after eating this meal, if you want to eat the next meal, the war needs to be over.

General Ke reappeared, but this time he did not burst out with any coercion, although the source array of hidden aura had been carved in the belly of the mountain, but he was still cautious, he looked at the crowd: "Presumably many people already know what this place is. That's right, we've gone straight to the outside of the Great Wall through secret passages.

And this is the rear of the alien coalition army, just outside, less than three miles away is the alien coalition army.

Soldiers, your secret combat mission is to surprise the rear of the alien coalition forces, so that the first place in the alien coalition forces cannot care for each other, and create opportunities for the comrades of the Great Wall to counterattack.

I want to ask you, can you do it? Answer me out loud!"

"Yes!" replied the 100,000 soldiers, without the slightest hesitation, only a spirit of generosity to die.

"Very good, you didn't disappoint me, you didn't disappoint the whole Terran, you are all good, you are all heroes of the Terran, eat now, after eating, set off for General Ben, let those alien cubs know the power of our Terran race!" General Ke roared, his eyes red, because he knew that these soldiers in front of him would probably never return to the Great Wall of Hope.

"Yes, General!" replied the 100,000 soldiers in unison again, and then, without any other words, began to eat.

General Ke fell in front of the cultivators and said, "You must have heard what General Ben said, and you already know the contents of the secret battle plan, so I don't beg you to act with the army to surprise the alien alliance."

After the army is drawn in a while, you can go wherever you want, and don't come back here, after the army is opened, the general will collapse the passage, leaving no chance for the aliens.

If you want to go back to the Great Wall of Hope now, then you need to find your own way, and that's all I have to say, I wish you all good luck!"

After that, General Ke just left without any delay, leaving the scattered cultivators looking at each other, and they were a little dazed for a while. Take a look at the latest chapter of the "Super Extraction System Claw Book House" to read for free for the first time.
