Chapter 847: He Learns Bad Things Very Quickly

When they first entered the underground passage, Gordon and the others were still making jokes like "It's useless to just plug the opening of a rat hole."

But when they really went deep into the huge underground cave, the hunters and even the Elfang Hounds entered a silent state, fully alert.

The last time they came here was nearly two years ago. Fortunately, the terrain in the underground cave was not complicated, so they didn't get lost easily.

Their first target was the cave with the largest space, which was the place where they fought with the Mantis last time.

There were a lot of metal devices, ruins, etc. from different regions and different periods scattered there. These things were combined under the control of the Mantis's silk thread to form a super-giant mechanical beast, which was the "Queen's Ruins City."

Gordon's idea was also very direct.

If the mechanical beast "Ruins City" is regarded as a set of armor, then the parts collected by the Mantis are the parts of the armor.

Just like the hunters' wrist armor, greaves, helmets, etc.

Even the sloppiest hunter wouldn't leave the parts of a set of armor scattered all over the place, so that he couldn't find them, right?

The same should be true for the mantis. The huge underground cave is probably the "equipment box" where the mantis stores the parts of the mechanical beast.

If they can find some of the metal parts lost in the East Doruma Arsenal or the Gioris Fort, they can use it as direct evidence that the mantis participated in the attack on the fortress.

At that time, they can choose the time to hunt the mantis according to the situation.

"Ka Ka."

There were two slight sounds like rolling stones in front of them. Gordon stopped immediately and raised his fist to signal his companions behind him to stay alert.

In order to avoid being exposed too early, they turned down the brightness of the oil lamps on their waists. They couldn't see anything more than ten or twenty meters away, and could only rely on the Elu who had night vision to explore the way.

The noise just now was made by the pig chop and others, which means "dangerous situation".

After waiting for a while, Xianglan ran back quietly, "There is a male mantis wandering at the entrance of the tunnel ahead, meow, do you want to kill it?"

The male individual strength of the mantis is very ordinary, barely reaching the level of a two-star monster. With their strength, they can kill it quickly.

But this is in the opponent's nest. Who knows if it will release some warning pheromones before death? It will be a big trouble if it attracts a group of people.

Gordon made a "denial" gesture and whispered, "Leave it away."

Xianglan's cat eyes reflecting fluorescent light blinked twice, nodded, and ran away.

After waiting for a while, a sound similar to rolling stones came from the front again, which meant "the alarm was lifted."

The hunters took another step and moved forward cautiously.

They didn't know whether it was Zhucha or Xianglan who led the male mantis away, but they were not too worried. With the strength of the two Elu, it was easy to slip away a monster of this level.

Similar situations happened twice afterwards.

Under the alternate enticement of Zhuchop and Xianglan, the hunters arrived at the huge cave at the target location without alarming more male mantises.

They waited for a while at the entrance of the tunnel leading to the cave, and waited for the cats and dogs with dark vision to quickly check the environment in the cave. After confirming that there was no danger for the time being, they entered with confidence.

Gordon took off the kerosene lamp from his waist, turned it up, and put it on the ground. The orange light illuminated a large area.

He said: "Use the oil lamp as the gathering point, disperse the investigation and search, send a signal when you find something, and gather at the lamp to meet the enemy when there is danger."

"Understood." Hayata Ansil nodded.

The hunters were about to disperse when they suddenly heard Xianglan's meow, "Occasionally found meow!"

"?"

The hunters, including Zhuchop, were full of question marks.

We haven't started looking yet, and you have found it?

Xianglan didn't say anything, sniffed carefully left and right, and ran in a certain direction.

The hunters hurriedly followed.

Soon, they came to a metal object that looked like it weighed at least two or three tons. It looked like a part of some large machinery.

Pork Chop and Ansil looked at the part for a while, exchanged a few words in a low voice, and soon reached a consensus.

"What is this?" Gordon asked.

"It looks like a bearing connection that connects the head of the dragon-striking spear to the steam propulsion component." Ansil replied.

"Wow!" Gordon was stunned and looked at Xianglan, "There are so many messes around, how did you find this all of a sudden? Aren't you and Hayata both mechanical idiots?"

Hayata: "?"

Aren't you the same? ! I'll deal with you later

Xianglan pointed proudly at the gap between the metal parts, which was stained with some black grease.

This doesn't mean anything. The grease used to lubricate metal parts will also become dark and sticky after being used for a period of time.

But Xianglan is very sure that this is not blackened engine oil, but the smell of "black oil".

Pork Chop and Liefeng also came over and smelled it carefully.

"How is it?" Gordon asked Pork Chop.

Pork Chop scratched his ears, "It is indeed meow, Xianglan's sense of smell is much sharper than ours meow, I didn't notice any smell here just now meow."

"Meow~" Xianglan proudly put her hands on her waist and puffed out her belly, "There are some things around that also smell of black oil meow!"

The hunters followed Xianglan and looked around, and found something that looked like a cannon base and something that looked like a fragment of a city gate. The materials were not limited to metal, but everything.

"You have a wide range of interests." Anshil said.

"Sketch down the shapes of those things." Gordon said to Hayata, who was good at painting.

There were a lot of them, so Hayata gritted his teeth, took out a pen and paper, and quickly copied and sketched them.

Gordon returned to the part of the dragon-beating spear and checked the surface of the part and the marks on the ground.

He quickly came to some conclusions, "This thing has just been brought here not long ago, probably one or two days."

"Why?" Anshil asked.

"The drag marks on the ground are very clear and new, and the scratches on the surface of the parts are shiny new. Although the desert here is relatively dry, there is some moisture in the underground cave.

If metal parts are left here for a while, these scratches will become dark and rusty."

As he said, Gordon searched along the drag marks on the ground and soon found a huge pit.

That was obviously the hole left by the mantis when it burrowed into the ground and left.

Gordon squatted down, stroking the marks left on the edge of the pit, and looked back at the drag marks. His face darkened.

He patted the dust on his hands and stood up, "This is a big trouble."

"Because the mantis has left?" Ansel asked, looking at the marks.

Although he was not as good as Gordon in trace analysis, he was also skilled.

"It's not that simple, look here." Gordon pointed to the drag marks extending from the pit to the metal bearing, "Look at these, very sharp, very deep scratches, right?

There is no such sharp part on the metal bearing, it should be the head of the dragon-striking spear."

Gordon circled the pit and soon found some deep scratches that entered the pit.

"Imagine the scene. Mantis had a lot of harvest and dragged a lot of 'harvest' back here, including the Dragon Striker with the bearing connected.

It should not be long after that Mantis took the Dragon Striker away again. Because the bearing was heavy and in the way, it removed the bearing and took the Dragon Striker's head alone."

"Take the Dragon Striker's head?" Ansel quickly reacted, "As a weapon?"

"Yes, I think."

Gordon stared at the deep pit, "The worst case scenario we considered before should be correct.

The attacker of the East Doruma Arsenal should not be Mantis, but another powerful monster. The black oil was left by that monster.

It destroyed the arsenal and took away gunpowder and many metal objects including the first generation Dragon Striker.

It is very likely that Mantis did not participate in that time. After all, we searched for After so many attempts, no relevant clues were found.

Some time after the first attack, the monster attacked Gioris Fort again.

This time, the mantis participated. It is not clear what role it played in the attack. An accomplice? A thief? Anyway, after the attack, it took away a large amount of loot and brought it back to its nest.

Then."

At this point, Gordon changed the subject, "Scholars have said that the mantis should have a high IQ and is very good at learning and imitating, otherwise it would be impossible to control such a mechanical behemoth."

An Xier pulled the corner of his mouth, "It didn't catch up the first time, and it might have been observing in secret.

The second time, it followed the black oil monster's ass, watched the black oil monster destroy the fortress, and tasted the sweetness.

So the third time, it took weapons and prepared to rob it by itself? "

"It should be, it learns bad things very quickly."
