As the huge stone fell, it collided with the side of the pit, rumbling and crashing, and finally fell to the bottom with a loud thud.

Athena: "It's about 150 meters deep here. ”

Zhang Hao shrugged, just looked at the bottom of the pit, and casually threw another burning fireworks stick down.

In the flickering orange firelight, Ran Ran fell to the bottom, where there was a cloud of dust, which had been smashed by the boulder just now.

Suddenly, a black shadow burst out from the bottom of the pit and struck the firework stick, breaking it into pieces and scattering it.

Zhang Hao: "Hehe, this is it." Uh, why does it look familiar? ”

Athena: "Highly similar to the vampire vine, Your Excellency Zhang Hao." ”

Zhang Hao nodded: "That should be relatively simple, this product should be a plant, right?" Athena"

Athena: "Definitely a plant." ”

Zhang Hao's figure quickly retreated outward, and soon returned to the collapsed building outside, throwing out a bunch of Daqing animal carcasses on the ground, which was the group of big green wolves he killed in Daqing at the earliest.

The bloody qi quickly drifted out, Zhang Hao felt that this was a bit slow, so he simply took out a domestic loudspeaker mobile phone, played a dog barking song, and threw it on the pile of corpses.

He himself sprang into the air and left the pile of wolf corpses.

In less than thirty seconds, the ground began to shake slightly, and more than a dozen pitch-black vines rumbled out of the ground, quickly enveloping the pile of wolf corpses.

Zhang Hao's body fell quickly, and he pounced directly on the outermost vine.

The vine seemed to sense something, writhing as if imagining Zhang Hao attacking here, but its movements were not as fast as Zhang Hao's.

In the next second, Zhang Hao stepped on this vine, and Athena, who was already ready, immediately sent out a prompt: "Successfully collected a mutant plant vampire vine." ”

The dozen or so vines from before also disappeared, leaving only the mobile phone still there barking non-stop.

Zhang Hao threw out the batch of wolf corpses again, which was taken back from the vampire vine that had just been collected into the space tower, and it could be reused.

Flying dozens of meters into the air again, Zhang Hao looked at the vampire vine in the space tower.

Athena intimately marked its size and her own speculation: the mutated plant vampire vine, weighing 992 tons, the longest vine is 500 meters, and it is suspected to be level seven.

"it!" Zhang Hao saw the last suspicious content, and directly burst into foul language.

He hadn't seen a level 6 mutant beast yet, but he first got a level 7 mutant vampire vine, which was really a joy!

And this ...... It's huge! This amount of strengthening potion is estimated to be enough for him and the agents to drink to the seventh level, right? It's just more wasteful.

It is more cost-effective for two or three people to be promoted to the eighth level of the Awakened.

After waiting for a few minutes, the wolf corpse and the dog barking domestic machine below did not suffer any attack, and then looked at the trembling mutated vampire vine in the living storage space of the space tower, Zhang Hao shrugged: "It seems that there is only this product here, and I can't catch more good things." ”

went down and took back the bait and the domestic machine, and got a seventh-level vampire vine in his hand without spending anything, Zhang Hao is now happy in his heart.

After entering the passage again, Zhang Hao turned his head to look at the entrance, and with a wave of his hand, he released a large pile of construction waste, blocking the passage mouth again.

Now was the time for him to enjoy the cave treasure hunt alone.

Humming a little tune out of tune easily, Zhang Hao flew back to the deep pit of the elevator and landed down without stopping.

When I got to the bottom, I saw a black hollow on one side, which was where the vampire vine had appeared just now.

Collecting all the garbage hidden in the direction of the entrance, Zhang Hao threw out fifty combat robots, all of which turned on the spotlights on their heads and illuminated the road in front of him.

This is the underground base in Zhang Hao's imagination.

The floor height is almost ten meters, the architectural style is wide and simple, and the walls and floors are marked with various signs and arrows indicating the direction, and some of them are flashing bright fluorescent.

Zhang Hao had the battle robots disperse into twenty groups, two in groups to investigate in all directions, and he let the remaining ten battle robots light up and wander around this underground base at will.

The radio here is still not easy to use, and Zhang Hao can't command those robots in real time, but this is the lair of the seventh-level vampire vine, there should be no other mutated creatures, and this kind of overlord-level mutated creature will naturally kill other mutated creatures.

Turning around, Zhang Hao found a place that seemed to be a power supply room or something.

Let Athena analyze, Zhang Hao started to connect several damaged lines, a slight fluttering sound sounded one after another, and a pale and faint emergency light lit up in the entire underground base.

Zhang Hao applauded himself twice to show his praise, and walked out of the power supply room to look at the space.

There were wide passages everywhere, and there were some scattered things, including vehicles, instruments, tools, materials, and he put away all the things in the places where Zhang Hao passed by anyway.

After wandering around for a while, Zhang Hao stopped exploring by himself, released the steel fortress into it, and began to eat unhurriedly, take a nap for an hour, and wake up to start practicing boxing.

After such a set of processes, the time went from noon to evening.

Before going to bed, Zhang Hao sent five combat robots to the elevator to guard, and the remaining five robots only left one outside the steel fortress to call the police if something happened, and the remaining four also scattered and joined the search for the entire underground base.

Zhang Hao originally thought that this military base would be finished in the afternoon, but by the time he finished reading the book and eating dinner, the robots still did not return.

He was a little strange, could it be that there was some enemy here? Otherwise, why didn't these battle robots come back?

Athena said that this possibility is very small, because these combat robots have a self-detonation system, and once they encounter an enemy and cannot escape, they will self-destruct, and the probability of all robots not having a chance to self-destruct is very low.

The movement that erupted from this quiet underground base could be heard casually.

Fortunately, Athena still had two hundred combat robots in stock, and Zhang Hao simply released them all, and asked Athena to continue to make a batch of spares.

Finally, before Zhang Hao went to sleep, some robots returned one after another, and Zhang Hao synchronized the information in their database, and handed it all over to Athena to deal with, and he still slept on time.

The next morning, Zhang Hao woke up in the steel fortress, and he didn't remember where he was for a while, and only after a moment did he ask, "Athena, how is the situation?" ”

Athena: "Your Excellency Zhang Hao, everything is normal. The robots are all returning one after another, and there is no loss. ”

Zhang Hao washed his face and brushed his teeth and ate breakfast while listening to Athena's projection tape explanation.

It turned out that this was not a military base, or that small military base was just a superficial building on the upper floor, and the base below was the main one - the Canadian and American war readiness material depot.
