The vault was not directly related to Elizabeth Sobek's research team, and at best provided some intelligence and logistical support.

Without access to the heart of the plan, the people in the vault naturally have no way of getting the full picture of what is going on.

Anthony Hogan is likely to be the person in the vault who knows the most about the plan, and it is difficult to extract more useful information from the other working Focuses.

After scanning all the messages left by Focus, Lu Xiao learned the number of this shelter - 053.

Even without taking into account the numbers that followed, the existence of Vault 53 proves that there were 52 other functionally similar underground spaces before it.

There is no doubt that Vault 1 is the place to solve all the mysteries, and the super-strong brains who fought for humanity in despair must have died there.

It's a pity that after searching the entire shelter, Lu Xiao didn't find any information related to Vault 1.

When Lu Xiao and Aletheia, who were acting separately, returned to the center of the hall almost at the same time, Yongzhen had already finished tidying up the main control room and the largest bedroom of the shelter, and the portable base station brought by Alethea had also been installed.

"The base station I made has a wide range of transmission and reception, and the effective signal transmission range can reach 5 kilometers without a large number of obstructed objects."

Aletheia, who was acting separately from Lu Xiao, found a good thing inside Vault 53 - a map.

Although after nearly a thousand years of changes, the situation on the surface has long been very different from that in the map, it can still be used as a reference, so that Lu Xiao and Yongzhen can install more base stations near the base to complete signal coverage.

In the first month of arriving in the Zero Dawn World, Lu Xiao and Yongzhen had never seen a single human when they were out exploring.

After a purge and the extinction of tens of billions of humans at their peak, the Earth is now dominated by the mechanical beasts that can be found everywhere in the wild.

According to the information left in Vault 53, Lu Xiao has a general understanding of the types, names, and abilities of mechanical beasts.

The Warden, one of the weakest mechanical beasts, resembles a clawless velociraptor with two hind legs, as documented in the data.

Although the Watchers are very poor in combat, they have a wide range and move quickly, and it is difficult to run away once they are targeted.

The cow-type mechanical beast that Lu Xiao and Yongzhen encountered in the wild before was called the Broad-headed Beast, and its attack pattern was similar to that of the Ox, with infinite strength and strong defense under the heavy body support, it was a medium-sized mechanical beast that was relatively difficult to deal with.

If there is a medium-sized one, there will naturally be a large one, and when Lu Xiao read the information, he was speechless and saw the projection of the giant mechanical beast called Thunder Fang.

"This thing should be based on a Tyrannosaurus rex, right?"

Thunderfang's total length is nearly 30 meters, and its height is also more than 10 meters, and the average mechanical beast stands at its feet like a pocket doll.

Moreover, the weapons carried by Thundermon are also quite terrifying, it is said that it has the powerful firepower to destroy an army in a short period of time, and its defense power is far above that of the Broad-headed Beast.

Thunderfang is the overlord of the mechanical beast on the ground, and in contrast, there is also an air overlord in the sky called the Storm Bird.

The number of Thunder Tooth and Storm Bird was not large, and Lu Xiao and Yongzhen did not see any of them in the month that they were in the wild.

If he could, Lu Xiao hoped that he would never encounter such a super-large mechanical beast.

In addition to the ubiquitous watchers, the relatively common automatons include horse-based walkers, chocobo-like herbivores, aggressive saboteurs, and medium-sized automatrons often seen in the air, such as the Lightning Hawk.

Using Vault 53 as a base, Lu Xiao and Yongzhen installed a large number of portable base stations nearby.

After completing the preparations, Alethea will release the drone that has been prepared in advance.

Through the mechanical beast components brought back by Lu Xiao and Yongzhen, Alethea made some modifications to these drones, so that they could absorb mechanical energy by eating food.

On the one hand, it maintains the perpetual motion of the drone, and on the other hand, it can also be camouflaged by the identification code stripped from other automatons to prevent the drone from being attacked.

Alethea gained some inspiration by assembling the automatons, and reconstructed some of them in her own way, allowing them to obey the orders of several of her authorities and keep the base safe.

The base's security and communications systems are basically in place, and the next step is to begin to expand outward.

In this world full of automatons, there is no shortage of electronic components and metal materials.

Lu Xiao and Yongzhen put the mechanical beasts destroyed in the wild into the space and the demon refining pot, and regularly returned to the base to unload them through teleportation during the exploration.

Alethea used these materials to build more portable base stations, gradually expanding the range of the signal transmission tower

With Focus, Lu Xiao and Yongzhen looked a lot more relaxed when facing the mechanical beast.

After Alethea repaired and restarted the main control terminal of Base 53, Lu Xiao and Yongzhen Focus carried out a direct data connection with the base terminal, and could fully transmit data to the base at any time within the range covered by the base station signal.

is like the saboteur in front of Lu Xiao.

Carrying a pulse energy cannon on their backs, the Saboteur is the toughest type of medium-sized automatron, with excellent mobility and incredible firepower, making it a hassle to fight head-on.

Focus can retrieve the data of the base and mark the weakness of the saboteur in high brightness in front of Lu Xiao's Yongzhen's eyes.

Compared to other relatively docile herbivores, the saboteur is very aggressive, and when encountering other types of automatons, they will not hesitate to take the initiative to attack, plundering the opponent's energy tank to replenish themselves.

Lu Xiao stood on a large tree and held his breath, pulling the folding bow full of bowstrings, and the special arrows polished by Althea using the armor plates of the mechanical beast were aimed at the target, pointing directly at the saboteurs who were attacking the Angbu.

"Whoosh!"

Off-string arrows traverse space in a fraction of the time, striking the energy canister behind the saboteur like a tail.

Without an external energy tank, the saboteur's time to continue to move is greatly limited, and if a new energy supplement is not available as soon as possible, it will cease to function after a maximum of ten minutes.

The attacked saboteur stopped attacking the stroller and turned his head to look in the direction from which the attack had originated.

"Bang!"

Lu Xiao, who was two kilometers away, fired another long-range sniper shot into the pillar of the pulse energy cannon on the saboteur's back, stripping its largest weapon from its body.

"Whoosh!"

Taking advantage of the fact that the saboteur was attacked one after another and the center of gravity was unstable, Lu Xiao calmly shot the third arrow, hitting the saboteur's head, completely stopping its physical activity.

The saboteurs usually act in groups, and the loss of one companion allowed the other three saboteurs to discover Lu Xiao's traces.

They gave up the Angbu who had already run away, and sprinted in the direction where Lu Xiao was.

Just as Lu Xiao bent his bow and arrows and planned to continue shooting this group of saboteurs, a loud battle cry suddenly erupted from the bushes next to the saboteur's sprint path.

A group of strangely dressed humans burst out of the forest with spears in hand, and a few more archers appeared on the branches behind them.

"Oh?"

Lu Xiao put down her bow and arrow for the time being, and looked at these second-season humans who met for the first time with interest.

Their clothing looks primitive, sewn from animal skins and linen, and most of the outer layers of their clothes are woven with some metal armor, which is supposed to be taken from the mechanical beasts.

Most of the weapons in these hands are made of the same material, and they can deal effective damage to automatons when charging in groups.

The charging saboteur did not expect an ambush in the woods next to him, and it was too late to react when he was ambushed.

The humans who cooperated near and far relied on their numerical and surprise advantage to successfully dismantle the three vandals that were untouched.

"Clean up the battlefield! Take away the useful parts, fast! ”

Lu Xiao hid in the big tree and silently watched the group of humans, led by a black man with a strong physique.

Before launching the raid, he had noticed the ultra-ranged attacks of the Hit Saboteur, and had been watching warily as his companions collected parts for the automatons.

Unsure whether the other party was friendly or not, Lu Xiao did not plan to expose himself for the time being.

'Follow them quietly to the tribe, and you may be able to get all the useful information from the tribe's higher-backs.' ’
