With Lu Ning leading the way, the group moved very quickly and soon approached the walls of the border fortress.

The guards on the city wall also noticed the unusual situation in this area.

A blood mist capable of devouring all diseased beings and calamity beasts!

The commander of the border fortress immediately ordered the nearby machine guns and soul crystal cannons to turn and aim at the source of the blood mist.

Yan Feng immediately shouted, "Don't fire! We are a rescue team from the Mist Bureau!"

Lu Ning cooperated to dispel the blood mist above, and the people on the city wall could see Lu Ning and the others inside the blood mist.

However, as the blood mist above dissipated, a large number of infected individuals and calamity beasts leaped up, attempting to rush into the blood mist from above and attack Lu Ning and the others.

They were met with Lu Ning's gunfire, Yang Xue's energy beams, and Yan Feng's flames.

Upon seeing Lu Ning and the others in the blood mist, the guards were all invigorated.

The leading commander smiled: "It's you guys from the Fog Bureau?! Head towards the city gate, we'll meet you!"

Under the commander's guidance, the group immediately moved towards the city gate, killing a large number of diseased people and monsters along the way.

Within minutes, they arrived at the gate of the border fortress.

Lu Ning controlled the blood mist to block the city gate, and then the commander ordered the city gate to be opened. After everyone quickly entered the city, the city gate was closed again.

The commander was already waiting inside the city gate.

Upon seeing Lu Ning and the others enter, he quickly stepped forward, saluted them, and then said with a smile, "You've all worked hard! I am Farin, the commander of the Fifth Border Fortress."

Yan Feng and the others returned the greeting. Then Yan Feng said, "Time is of the essence, there's not much time for farewells. Let's pack up and prepare to retreat."

Upon hearing this, Farin hesitated for a moment before speaking, "There are a large number of diseased creatures and monsters outside the border fortress. Once they leave the fortress, most of our guards are just ordinary people. Even with weapons, they cannot survive the monster horde. Do you have any countermeasures?"

At this point, Farin explained, "It's not that I'm unwilling to leave, but if you don't have a plan to preserve the retreating main force, you might as well take the scientists doing research in the border fortress and the data they have, and we'll stay in the fortress to provide you with fire support."

Upon hearing Farin's words, Yan Feng and Colin frowned slightly.

Yang Xue said with a solemn expression, "If you stay in the border fortress, you will have almost no chance of survival. The horde of calamity beasts has only just begun. You may have noticed that there are not many calamity beasts at the Fifth Border Base right now, but more and more infected people and calamity beasts will come looking for you by following the pure mental fluctuations of humans. Once you run out of supplies, you will be doomed."

Farin grinned, his smile carefree, and said, "We are all soldiers, and dying on the battlefield is a fitting end for us. But these scientists who do research are different. They study the fog and analyze mental pollution. They have more value in living than we do."

"If not everyone can survive, at least let the most valuable people survive first. They are the torch that will keep human civilization going."

Colin and the others fell silent.

Colin then looked at Lu Ning, who stood calmly to the side: "Lu Ning, what do you think? Can you take everyone away?"

Yan Feng and the others standing nearby also looked at Lu Ning.

Lu Ning's high-risk soul weapon greatly shocked them.

Yan Feng, no longer displaying his previous nonchalant attitude, asked, "Lu Ning, could you expand your blood mist a bit? What's the maximum area it can cover? Can it envelop everyone?"

Lu Ning asked, somewhat puzzled, "Why do we have to think about breaking through? There aren't that many monsters here. We can kill them all. Once we've killed them all, we can retreat safely."

Everyone was taken aback when they heard Lu Ning's words.

A series of question marks appeared in Colin's and his companions' minds.

Farin, who didn't know much about Lu Ning, was even more bewildered at this moment.

He then glanced warily at Lu Ning, before looking at Yan Feng and the others.

He considered his words carefully before speaking, "This...brother from the Mist Bureau, is your mental state a bit too polluted? You seem to be a little off?"

Farin vaguely wanted to tell whether the guy in front of him was crazy.

After all, how could a normal person think of killing so many monstrous beasts and infected beings?!

They are just regular guards, not an army of awakened ones!

Lu Ning said with a serious expression, "My mental pollution level is 0, and my mental state is perfectly normal."

Farin: [?_??]

Yan Feng, standing to the side, said helplessly, "With so many infected and monstrous beasts, we can't possibly kill them all, can we?"

Lu Ning calmly said, "I think I can kill them all."

Upon hearing this, Colin and Yanfeng both perked up.

They exchanged a glance, and Colin said, "You think you can do it? Why don't you give it a try?"

Upon hearing this, Alex and the others looked at Colin and Yanfeng with a lot of questions in their minds.

Are these two going crazy along with Lu Ning?

However, Lu Ning had already nodded: "Open the city gates."

Seeing that Farin was hesitant, Yan Feng immediately said, "Don't worry, Commander Farin, if anything goes wrong, I'm willing to take full responsibility!"

Colin nodded and said, "No matter what problems arise, we will definitely send those scientists and their data back safely. If Commander Farin is worried, he can have them prepare. If the situation becomes uncontrollable, we will evacuate them at any time."

Yang Xue also spoke up, "In any case, there's no harm in giving it a try, is there?"
