With the ability to absorb the mental pollution of two demigods at once, coupled with a significant increase in his strength, Lu Ning's efficiency in absorbing mental pollution has more than doubled.

In just a few hours, the source of mental pollution in Lu Ning's mental sea was about to become uncontrollable again.

So, Lu Ning entered the Tower of Ruins once again.

This time, Lu Ning directly advanced to the mid-level demigod, and after advancing to the mid-level demigod, his mental power also increased significantly.

When Lu Ning stepped out of the Tower of Return to Nothingness again, the group of exiled demigods in the plaza outside were all dumbfounded when they noticed Lu Ning's mental fluctuations.

Lu Ning, who had just been promoted to the demigod level, is now actually a mid-level demigod.

They then seemed to be deep in thought.

It's likely that Lu Ning absorbed their mental pollution and gained a large amount of mental power, which is why he was able to improve.

But that's demigod-level mental pollution, something even demigods can't remove, and wouldn't dare to continue improving upon.

Lu Ning is not only able to remove these mental pollutants, but he can also use them to improve himself?

Even though they knew Lu Ning was completely different from other beings, this still exceeded their expectations.

After reaching the intermediate demigod level, Lu Ning's efficiency in absorbing mental pollution increased again, and the amount of mental pollution he could absorb at one time also improved significantly.

After absorbing twice more, Lu Ning absorbed all the spiritual pollution from the exiled demigods.

His strength is only one step away from that of a high-level demigod.

Lu Ning simply took the opportunity to absorb all the spiritual pollution from all the living beings in the exiled city-state.

With his current strength, once he pries open the Tower of Ruins, he can cover the entire Exile City-State in one go and absorb it all!

When Lu Ning absorbed the spiritual pollution from all the exiled beings, the spiritual power he gained was not as great as the sum of the spiritual pollution from all the exiled demigods, but it was still quite good.

When he entered the Tower of Ruins again, he immediately raised his mental power to the level of a high-level demigod.

At the high-level demigod level, the increase was nearly one-tenth.

Unfortunately, the mental energy required for the advancement of a high-level demigod is much greater than imagined. He estimated that even if he absorbed all the mental pollution from humans, he wouldn't be able to improve much further.

After all, the number of exiles here far exceeds the current human population.

Although he has only reached the advanced demigod level, Lu Ning is already very satisfied.

After all, he had only just broken through to the demigod level.

With his current strength, plus the two divine artifacts, he should have a chance to deal with the moon even if he faced it alone, right?

All the exiles present were completely numb when they sensed that Lu Ning's mental fluctuations had reached the level of a high-level demigod.

This rate of improvement has exceeded their understanding.

When Lu Ning emerged from the Tower of Ruins once more, he looked at the exiled demigods in the plaza.

At this moment, these exiled demigods looked at Lu Ning with eyes full of respect.

Lu Ning absorbed the spiritual pollution from the demigods, giving them a path to continue. He also absorbed the spiritual pollution from all the exiled beings in the entire exiled city-state, which greatly increased the exiled beings' future potential.

It can be said that Lu Ning's actions were a great kindness to all the exiles.

Of course, Lu Ning himself did not think so.

After all, many exiles died trying to protect the Earth.

Lu Ning said calmly, "I'm going back to Earth now."

After Lu Ning finished speaking, the Void Zerg Queen said, "Lord Lu Ning, I intend to go with you."

Hearing this, Lu Ning was taken aback.

Before he could say anything, the leaders of various top races beside him, including the Lightborn Clan Chief, the Shadowcrown Clan Chief, and the Tarlin Clan Chief, all spoke up, expressing their desire to go to Earth with Lu Ning.

Lu Ning paused for a moment, then asked, "Why do you want to come along?"

The Shadow Crown Clan Chief spoke up, "We wish to attempt a breakthrough, but perhaps we will need Your Excellency Lu Ning's assistance."

Lu Ning thought for a moment, then suddenly realized, "You want me to absorb the mental pollution for you when you break through?"

The group of exiled high-ranking demigods all nodded in agreement.

Lu Ning shook his head and said, "I feel that I am not yet able to absorb the mental pollution you experienced during your breakthroughs, so it would be useless for you to come with me."

If Lu Ning uses the Tower of Return to Nothingness, he should have a chance to absorb the spiritual pollution they experienced when they broke through to godhood.

The problem is, he doesn't currently intend to take the Tower of Ruins with him.

The Land of Return to Ruins exists in relation to the Tower of Return to Ruins.

Once Lu Ning takes the Tower of Return to the Ruins away, the Ruins of Return to the Ruins will likely collapse very quickly.

The number of exiles in the Ruins of Return is so large that even Earth cannot contain so many.

He couldn't just leave these exiles to be swallowed by the fog and do nothing.

These powerful exiles had just made great sacrifices to protect the Earth; he couldn't do something like this.

However, if these demigods were to break through to the god level within the Ruins of Return, the breakthrough process would be so intense that even the Ruins of Return could not isolate the breakthrough fluctuations within the mist.

In this way, the Land of Ruins will likely be surrounded by evil gods.

This is not a good thing for the Land of Ruins or for Earth.

However, although Lu Ning cannot absorb the mental pollution when a demigod breaks through to godhood, he has a feeling that once his mental strength improves further, he should be able to do it once he reaches the bottleneck of a high-level demigod, without needing to wait until he reaches godhood.

Upon hearing Lu Ning's words, the group of exiled demigods immediately showed disappointment.

Then, the Void Race Queen spoke up, "Even so, I intend to follow you to Earth. Earth should be under attack by the Mist soon, right? I can lend you a hand."

The other high-ranking demigods also nodded in agreement.

Lu Ning can absorb their spiritual pollution, which means that as long as Lu Ning is around, they will eventually have a chance to reach the god level.

This is so important to them.

Now they naturally hope to improve their relationship with Lu Ning.

Lu Ning glanced at the enthusiastic exiled demigods, paused for a moment, then nodded and said, "Demigods can come along."

"What about the saints? We can arrange for quite a few saints to come together."

Lu Ning shook his head: "Not at the moment."

Currently, humanity only has nine base cities left, and the number of saints among humanity is now sufficient to protect these base cities.

Going there more won't lead to much improvement, but for demigod-level powerhouses, going there will definitely result in improvement.

Moreover, the Exile civilization also needs to hunt mist monsters and obtain pale crystals to survive in the Ruins of Return.

Only a few demigod-level powerhouses are needed, because demigod-level monsters are rare in the Ruins of Return, but there are quite a few saint-level monsters.

Without a Saint-level expert leading the team, the hunting party would likely suffer heavy losses.

Seeing that Lu Ning did not need a Saint-level expert, the high-ranking members of the exiled civilization did not insist.

Afterwards, the group of demigods followed Lu Ning away from the Ruins of Return and headed back to Earth.
