After thoroughly examining the changes within himself, Lu Ning resumed his cultivation.

Although the source of pollution from the flesh and blood source is difficult to temper, the resulting increase in mental strength is also significant. Lu Ning could clearly feel that he was one step closer to reaching the upper limit of the fifth rank.

He still needs to work hard to temper his mental strength.

The Mist Exploration Team may explore Mist No. 233 at any time.

That's where he returned to Earth; it might contain some clues.

Of course, it may also contain dangers.

He needs to become stronger; only then will he be able to investigate these clues and face these dangers.

Only in this way will he be able to find his way back.

Although it has been more than a year since Lu Ning returned to Earth, he still misses his parents and sister, and he misses that safer and more prosperous world and country.

…………

Five months later, Lu Ning consumed a large amount of soul crystals and finally raised his mental power to the fifth-level limit.

He felt the bottleneck, but this time the bottleneck did not stop Lu Ning for long; he broke through it in less than a day.

Lu Ning successfully broke through to the sixth rank.

After breaking through to the sixth level, Lu Ning's mental power surged from the size of a small lake to the size of a giant lake, and its quality also improved once again.

At the same time, the improvement in mental strength also promoted the further evolution of Lu Ning's physical body.

In addition, Lu Ning had been using his mental energy to temper his physical body, so his physical strength was now much greater than his mental strength, resulting in a significant increase in his combat power.

…………

More than half a month later, as Lu Ning was waiting for the establishment of the No. 233 Mist Exploration Team, a piercing alarm suddenly sounded over the base city.

This surprised everyone in the activity room.

"Six long and one short horn blasts... this means... a horde of monsters has appeared??" Colin's expression changed instantly.

As seasoned Awakened Ones, Ke Qing and Li Mu also had grim expressions.

"A horde of calamity beasts has appeared? How unlucky!" Li Mu frowned.

Wang Qiwen, Qiu Yuelin, and the other four newlyweds looked somewhat bewildered.

Zhong Caixuan frowned and said, "Captain, didn't our base city also experience a beast tide before? Why are you all so nervous?"

Ke Qing glanced at the somewhat puzzled crowd and asked, "None of you were Awakened before, were you?"

Aiha and the others nodded.

Ke Qing explained, "During the monster horde, ordinary people only need to stay in the base city and don't need to face endless monsters and infected people, but it's not the same for awakened ones."

"The Awakened Ones are required to guard the border fortresses and the city walls of the base, which is extremely dangerous. During each wave of monster attacks, many members of the Mist Bureau have sacrificed their lives."

Upon hearing this, Zhong Caixuan and the others' expressions changed slightly.

They then realized that they were no longer the ones being protected.

They are now guardians who protect others.

They will stand in front of the endless hordes of calamities.

Although they had been dealing with the disease outbreak before, the beast horde and the disease outbreak were clearly two different things.

Colin pushed up his glasses with a serious expression and said, "Don't think about it too much. Li Mu, take Caixuan and the others to the underground to retrieve the soul artifacts. I'll contact the director to find out what's going on!"

Li Mu nodded: "Let's go!"

Ke Qing and Lu Ning did not leave, since both of them possessed soul weapons. Lu Ning himself had multiple mid-level soul weapons, and low-level soul weapons were no longer of much use to him.

Colin took out his phone and called Li Yihang.

His expression then turned serious.

After hanging up the phone, Colin said, "It's an anomaly in the Mist 233. The mist over there suddenly rioted, causing a mental pollution storm to be born. This caused the calamity beasts and mutated beings in the mist to rush out and drive the calamity beasts and mutated beings in the wilderness to join the main force, reaching the level of a beast tide."

Ke Qing frowned and said, "The increase in mental pollution level in the Fog of No. 233 has slowed down recently, so why has this happened again?"

"I don't know, there must be something wrong inside the fog." Colin shook his head.

"We don't need to worry about that now. Besides guarding the base city, we also have a special mission."

"What special mission?" Ke Qing asked, somewhat confused.

Colin adjusted his glasses and said, "Fog 233 is expanding rapidly. It won't be long before it engulfs several border fortresses. We need to find a way to rescue the garrison troops at the border fortresses and the people from the Fog Bureau."

"What?! The fog is expanding rapidly?!" Ke Qing's expression changed instantly.

"Hmm." Colin's expression was equally somber.

"...Won't it encompass the base city?" Ke Qing asked, frowning.

Historically, there have been instances of fog expanding.

Once the fog expands and envelops the base city, that base city will essentially be rendered useless.

In the current environment, the relocation of so many people from a base city would be an absolute disaster.

After all, without the protection of the base city, all ordinary people would be directly exposed to the mental pollution of the wilderness.

In addition to the psychological and physical stress brought about by long-distance migration, a considerable number of people will definitely fall ill!

The disturbances caused by the disease will definitely cause secondary damage.

Historically, there have been numerous instances of small base cities migrating, and more than once.

In fact, some migration teams were completely wiped out, and even the awakened ones from the Mist Bureau were unable to escape!
