I have a full-time hero system

After several minutes, the "poisonous rain" gradually subsided.

The concealed archaeologists poked their heads out one after another after realizing that there was no danger.

In the desert city ahead, a large pit appeared.

Symbiotes have been completely destroyed, and even the city has been destroyed.

"Do you want to dig here?" Kim So-yeon asked.

Yuan Xiao shook his head: "This place has been polluted, we need to leave as soon as possible, no matter how much value there is in the city, we can only wait for the future.

The task of our team this time is not mainly based on archaeology. "

Kim So Yeon did not refute.

The scene is full of demon blood, mixed with poison, which is indeed very unsafe.

Yuan Xiao called the team to make an emergency move, bypassing the big pit, and they reached a safe place.

First of all, all personnel need to change their protective clothing. Although they are protected by clothing, many warriors are still affected.

However, these were already within Ye Qingdai's estimation range, she adjusted the medical team to intervene in time to control the disease to the greatest extent.

After a short rest, Yuan Xiao contacted the base camp.

Compared with them, good news came from the base camp.

The scouts discovered a medium-sized ruined city.

Therefore, Acar considered moving the base camp to the vicinity of the ruin city.

This is the first time in human history that a relic city has been discovered in such a northern part of the Old Continent.

"Maybe there are very high-value archaeological resources left," Ajar said enthusiastically, "it's worth exploring."

Yuan Xiao didn't object either: "There are many things we don't know about the sojourners in the northern part of the old continent."

He briefly explained the giants and symbiotic creatures encountered by his team: "It's not impossible to move the base camp near the city, but you have to be cautious.

If you act rashly, everything will be irreversible. "

Acar heard this, and his face was also very ugly: "It seems that this place is really weird.

So for the sake of prudence, we still organize a special team to clean up the city now to avoid unexpected sojourners. "

This is a prudent plan, and Yuan Xiao also agreed: "It's the best, but I still have to say, don't force it.

Only by being alive can we say that archaeology has value.

I don't want you to become the object of archaeological excavations in the future. "

Acar ended the call with a smile.

After contacting the base camp, Yuan Xiao continued to determine the next move.

Geographically, it is already very close to the center point of the Wall of Sighs.

According to speculation, it is the fountain of life that caused the wall of sighs, that is to say, where they are going, the fountain of life is very rich.

This also means that there are a lot of sojourners.

"So, this operation is very dangerous, and there may be no return," Yuan Xiao emphasized again, "Especially after seeing giants and symbiotic sojourners, if there are those who retreat, they can leave the team and go back."

The commanders of various countries looked at each other in blank dismay.

Sandra smiled: "At this point, opening the magic box is just around the corner. I don't think anyone would want to just go back like this."

Everyone nodded.

After all, as a witness to history, not everyone has the opportunity.

After the central idea was emphasized, Yuan Xiao never raised similar questions.

After the team rested, they soon started moving again.

This time from the original site of the city's remains, they found a road.

Of course, this road has long been overgrown with weeds and bushes.

However, having roads also means convenience. After cleaning, vehicles can barely pass.

In this way, after spending another two days, Yuan Xiao finally arrived near the destination.

Looking from a distance, a towering Optimus Prime stands in front of a plain.

"That...may be the device that creates the wall of sighs." Sandra muttered to herself.

Yuan Xiao took a telescope to look, and soon discovered that Optimus Prime was surrounded by a high wall.

Outside the high wall, sojourners are everywhere.

These sojourners were of different types, but they didn't fight each other, but all went towards the high wall.

The purpose of the operation is very simple, as long as the high wall collapses, they can smoothly enter the interior and obtain the fountain of life they want.

"Can you feel the fluctuation of the fountain of life?" Yuan Xiao asked Jin Soyan.

The latter nodded with certainty: "Very strong, that's the place."

Optimus Prime submerged into the clouds above, and this cloud formed a huge vortex.

"So," Yuan Xiao smiled, "I found the right place. The problem is that we have to break through the herd of sojourners outside the high wall."

"It's not a big problem," Sandra felt relieved when she saw the actual situation, "We still have [-] fighters and mechas, and our combat capabilities are superior."

Kim So-yeon shrugged her shoulders: "I just hope that I don't encounter too perverted sojourners."

"The crux of the matter is," Sandra stared at Yuan Xiao, "Commander, are you sure you want to do this?"

Turn off the device, stop the wall of sighs.

Yuan Xiao pondered: "I don't know, don't think about it now, the first thing we need to do is to be clear about the obstacles in front of us."

This is a statement based on facts. If the herd of sojourners around this area can't break through, it's meaningless to say anything.

A military meeting was held to assign tasks to the archaeological teams of various countries.

Faced with a large number of herds of sojourners, Yuan Xiao proposed a mode of taking turns to fight.

"In this way, we can ensure that the warriors can rest and adjust. Our plan is to gradually clear up the herd."

There was no objection, and the program began to be implemented.

The first attack is the empire, followed by the alliance, the federation, the duchy, Rirenwell and the combined city-state team.

The fifty Thunder Chan mechas under Yuan Xiao's command were on standby as a raiding force.

Once there is a special sojourner, or a mother sojourn that is difficult to deal with, it is their turn to appear.

Soon, the battle began.

The warriors and mecha equipment of the empire are all very heavy types.

Their mechs are generally five or six meters high, equipped with heavy artillery or large beam weapons.

This is the most effective means of tearing apart the herd.

A round of artillery bombardment, at the beginning, the herd of sojourners was in chaos.

But there are too many of them, and they quickly realize the threat of humans.

They immediately turned around and headed towards the human archaeological team first.

As they ran, the ground trembled.

"There should be tens of thousands." Yuan Xiao clenched his fists.

The battle on the front line is very intense.

After the long-range weapon bombardment, it was the battle between the warriors and the mecha team.

All kinds of brilliant martial arts were played, strangling all the sojourners that rushed over.

In addition to the common known sojourners, there are many that have not been seen.

But the archaeological team has no way to confirm them one by one, so they can only go all out to do the task of tower defense.

Scattered all over the sky, in addition to the flames of the explosion, there were also scattered limbs and broken arms, and red and green blood intersecting.

"Push the front line forward," Yuan Xiao was still calm, "The alliance's archaeological team is ready to replace.

Remember, when replacing, the front line cannot be compressed back by the sojourner. "
