In those days of Plants vs. Zombies

After dealing with all the zombies they encountered, under the guidance of the bumblebee robot in mid-air, the remaining beetle robot and spider robot left the place.

Rosemary also made her own suggestion at this moment: "Owner, do we need to follow and take a look?"

"Hmm... that's fine. Let's follow these mechas and see where they are going."

Mo Chen nodded and led everyone to follow the group of mechas in front of them.

Of course, the exploration team and the mechas still maintained a distance that was neither too far nor too close.

"Homeowner, according to the route these mechas are taking, they seem to be circling around here."

After following the mechas for a while, Wendy, who was studying the map, shared her findings.

"In a circle? How big is the circle? Where is the center of the circle?"

Mo Chen fell into deep thought and found that things were not simple.

"The area is not large, it only includes this industrial park. The midpoint of this circle is our destination, which is where the auto repair shops are located."

Wendy landed on the ground, stretched out her finger and drew a circle on the map, including the entire industrial park.

Then, Wendy pointed at the center of the circle, which was the coordinates of the auto repair shop cluster.

Ji Bing said: "Their movements are...very regular."

Euphemia nodded in agreement, "Yes, that's right, my hounds are like that, they also like to run around the manor."

Rosemary on the side added: "Patrol."

When Rosemary said the word "patrol", it was unanimously agreed by everyone present.

Patrolling means protecting something.

This group of robots patrol the industrial park, and their purpose is to protect the cluster of auto repair shops.

With his mind opened, Mo Chen immediately understood why the mechas appeared in the industrial park, and why they were fighting with low-level zombies.

There is a mechanic whose race is a magnetic mushroom spirit in the auto repair shop gathering place. This mechanic created mechanical soldiers to protect the auto repair shop gathering place.

Low-level zombies wandering into the industrial park will threaten the safety of the gathering place and wanderers, so the robots will attack the zombies.

"In that case, we don't need to continue following these mecha soldiers around in circles. Let's go directly to the auto repair shop gathering place."

Mo Chen made the final decision and then led everyone towards the auto repair shop gathering place.

Along the way, the group encountered a number of mechas here and there. They were also patrolling to protect the wanderers in the industrial park.

When the people from Manor No. 5905 passed by the mechas, they would take the initiative to make way and did not regard the exploration team as enemies.

Wendy couldn't help but sigh: "To be able to use a pile of scrap metal to create such a practical and intelligent automatic robot, this mechanic is really talented."

Mo Chen was very curious about the talent Wendy mentioned: "What do you mean?"

“In the modern world, there are strict technical levels in all walks of life, and the mechanic industry is no exception.

From the lowest to the highest level, mechanics are divided into eight stages, named after various metals.

From low to high, they are black iron, bronze, silver, gold, forged steel, mountain copper, mithril, and alloy.

The lowest-level Black Iron Mechanic can only participate in the simplest maintenance work, and only Bronze Mechanic is qualified to design and modify simple mechanical creations.

Silver mechanics can open their own shops and work independently, and when serving in the federal army, they can also come into contact with military machinery.

The Golden Mechanic can already be considered an expert in the field of mechanics and can serve as a professor in federal institutions of higher learning. Needless to say, the Forged Steel Mechanic and the Mountain Copper Mechanic are also experts.

As for the more advanced Mithril Mechanics and Alloy Mechanics, the mechanical creations they create are federal secrets.

Even the most well-informed plant spirit hero can’t get much exposure.”

At the end, Wendy expressed some emotion.

Mo Chen, who knew her true identity, couldn't help but wonder if the "most well-informed plant spirit hero" mentioned by Wendy was actually herself.

However, the secrets that even Wendy could not access made Mo Chen curious about the appearance of those mechanical creations.

Maybe one day in the future, we will be able to see Gundam and Transformers in the modern world.

"Although the materials used in the mechas we saw... uh... are indeed quite poor.

But being able to use these scraps of copper and iron to create a variety of automated robots with a certain degree of intelligence is at least at the level of a silver mechanic.

If better materials are used, this mechanic will definitely be able to reach the level of a golden mechanic."

It was obvious that Wendy was very interested in this mechanic whom she had never met before.

As a former plant spirit hero, Wendy has naturally come into contact with many plant spirit mechanics. The fact that she can give such an evaluation shows that the magnetic mushroom plant spirit in the auto repair shop gathering place is indeed quite capable.

Ji Bing at the side suddenly said: "Alloy Mechanic, I seem to have some impression of him."

As soon as these words came out, Ji Bing immediately received curious looks from the other four people present.

"I heard from Lan Bing's predecessor that twelve years ago, the captain of Lan Bing sent eight Lan Bing special forces to carry out a special mission.

The actual content of that special mission was to protect a couple who were both alloy mechanics.

The eight seniors who carried out the mission were all the best of Blue Ice, and one of them was an instructor.

But just one year later, the captain received the notice of the death of those eight predecessors.

The mission failed, and Blue Ice suffered heavy losses, gradually falling behind in the subsequent competition with other special forces.

It was not until the current captain took over that Blue Ice's situation improved and it no longer ranked last among the five major special forces."

Ji Bing revealed a shocking piece of news, which made everyone very happy.

Mo Chen thought for a moment: "The protection mission failed. Does that mean that the alloy mechanic couple is dead?"

Wendy nodded and said, "This is the only possibility. Every alloy mechanic is a person that the Federation attaches great importance to, and even sends special forces to protect them closely.

There are naturally many people who want to target the Federation's alloy mechanics."

It is said that there are quite a few of them, but in fact there is only one answer.

There is no other force other than the Empire that can go against the Federation.

"Let's stop chatting here and hurry on our way."

Mo Chen shrugged, reminding everyone not to forget their business.

Wendy and Rosemary quickly followed Mo Chen, while Euphemia walked to Ji Bing's side.

Wanting to hear more gossip, Euphemia asked curiously, "A Bing, so, which of the five special forces is currently at the bottom?"

Ji Bing was silent for a moment, then the corners of his mouth slightly raised.

Under Euphemia's expectant gaze, she slowly said two words: "Green Poison."
