[Magic Crystal Powder: This is an enchanting, forging, and alchemy material that can be easily obtained by mining or crushing magic crystals.]
After Sebastian pushed Ouyang Qianjin in front of the wooden box, Ouyang Qianjin reached out and scraped some of these things off the side of the pickaxe.
Although the quantity was small, about two grams, it was undoubtedly what Ouyang Qianjin was looking for.
Now.
She began to look forward to what news Zhang Mo, who was scouting ahead, would bring back.
In fact, Zhang Mo did not disappoint her.
Because of the current limited range that Ouyang Qianjin can control, she can only probe a depth of 200 meters in total.
So Zhang Mo returned not long after.
"How about it?"
After Zhang Mo returned, Ouyang Qianjin asked impatiently.
"Go in about 150 meters and you'll be able to get out. There's a huge fortress over there, guarded by four and a half centaurs."
Zhang Mo wiped his sweat and quickly said.
"fortress?"
"Yes, its name is 'Central Fortress'."
"Centrals Fortress? It seems that this exploration mission might be located inside."
Ouyang Qianjin squeezed her hands on her knees.
Anyway, at least for now
"Is there any way to lure the four centaur guards over here?"
Ouyang Qianjin looked at Zhang Mo and asked seriously.
"That's not very realistic."
Zhang Mo shook his head.
"What's the meaning?"
Ouyang Qianjin frowned.
"It's too far away. The cave we're in is probably just one of the passages leading to the underground city."
Zhang Mo gave a wry smile.
After hearing this, Ouyang Qianjin understood the general situation.
It is estimated that this passage is less of a 'passage' and more of a mine tunnel dug by cave dwellers.
Who knows, most of those 1.4-meter-wide caves around here might lead to that Sentors Fortress.
Mining, you know.
Isn't the fishbone mining method the most efficient, safest, and easiest mining method to implement?
"Let's go take a look..."
He didn't say much.
Since the other party has said so, Miss Ouyang naturally wants to see for herself to be sure.
So the group slowly emerged from the cave.
When Ouyang Qianjin arrived at the cave entrance, she finally understood the meaning of Zhang Mo's words.
Ouyang Qianjin is currently located on a large slope that leads directly to the fortress on the other side.
The entire slope is surrounded by a dense network of caves like these.
These caves are spaced at varying intervals, some more than ten meters apart, and others more than a hundred meters apart.
In Ouyang Qianjin's view, if these caves are all the same as the small hills she discovered, then wouldn't that mean the centaurs could quickly mobilize troops from here to any small hill?
On the opposite side of the cliff is a magnificent fortress with a classical feel.
The entire fortress was excavated from the underground mountain.
It fits perfectly, with no visible seams.
Ouyang Qianjin even suspected that the cave dwellers had hollowed out the entire underground to build this fortress!
Moreover, Ouyang Qianjin felt that, barring any unforeseen circumstances, the fortress wall they were seeing now was probably not the main gate, but rather a side gate used specifically for mining...
[Sentors Fortress: As a satellite city of the Orcish royal city, it is responsible for defending against external attacks. It has a large garrison and is easy to defend but difficult to attack.]
[Hidden Information: Centaurs Fortress is also one of the Centaur Kingdom's magic crystal mining and refining bases, storing a large quantity of finished magic crystals and magic crystal ore.]
Wuhu!
After seeing the feedback on the [Eye of Detection], Ouyang Qianjin couldn't help but shout in her heart.
This is both a large garrison and a large storage capacity.
Is this some kind of custom-made copy for myself?!
Whatever I need, you give me that.
She wanted to shout it out loud.
But it's impossible.
After all, it's still on someone else's turf.
It would be bad if we attracted all the orcs from the fortress on the other side.
However, as soon as she turned her head, Ouyang Qianjin started to have a headache.
Taking this fortress, or rather, completing Zhang Yuan's mission, will not be easy.
Such a fortress, coupled with such terrain...
Unless you have an absolute advantage in troop strength.
Otherwise, if they wanted to conquer the centaur fortress, they would likely be attacked from both sides in various ways.
Even if it's just to hold onto this cave we're in now.
The opponent can also exit from another cave and then circle around to attack from behind.
Another flanking maneuver...
It's back row again...
Can't you races from another world come up with some other tricks?!
"Young Miss, what should we do?"
The Zhang brothers were getting anxious.
They can see the information that Ouyang Qianjin can see as well.
But it was precisely because they saw the large number of defending troops and the fact that the area was easy to defend but difficult to attack that they became anxious.
After all, one wants to upgrade, and the other wants to complete the task.
If they can't complete the mission, then they'll just be wasting their time here.
However, since they don't have Ouyang Qianjin's ability to see hidden information, they don't know that this fortress is also a 'metallurgical fortress'.
"Don't panic, stay calm, I'm here, what are you panicking for!"
Ouyang Qianjin is also using her gaming brain to think of a solution.
Hearing Zhang Mo's flustered voice, she was instantly displeased.
Zhang Mo immediately shut up after being scolded.
Ouyang Qianjin's eyes remained fixed on the magnificent fortress ahead.
