Although the Endless Demon Territory also had day and night, the concept of time here was chaotic.

Lindsay had been training with Natasha to practice fighting skills these days.

In order not to make Harlequin feel like the whole situation was biased, he stayed in the Green Halo with her for an hour every day.

Both of them were mages, so meditating here was many times better than outside.

The plants here could not only purify the magic essence outside, but the effect of meditating inside was also excellent.

Moreover, because they had obtained the meditation tea, the effect was even better with the Moonlight Liquid.

Therefore, the two of them progressed very quickly.

As for Natasha, the key to her advancement as a battle mage was to practice fighting techniques.

While practicing her fighting skills, she also perfectly integrated her magic power into her short knives.

It was unknown what material Natasha's short knives were made of, but when Lindsay wanted to help her refine the following items in the Refining Pavillion, he had to pay 5000 magic crystals.

The Refining Pavilion actually made him spend 5000 magic crystals.

From this, it could be seen that her short knives were now even stronger than the Earth Spirit Rod in Harlequin's hands.

A few days passed quickly.

On the sixth day, a total of 865 monsters came.

Among them, there were 300 elite monsters and 565 ordinary monsters, all of which were between Level 5 to 10.

The monsters' intelligence was also getting higher and higher, and they actually became much more orderly.

They did not charge forward so recklessly, and there were still some strategies that they did not know.

However, the other six defense towers, as well as Natasha and Harlequin's powerful strength, made them all weak and useless.

On the seventh day, 790 ordinary monsters and 380 elite monsters came.

They were all level 5 to 10 monsters.

The monsters were even stronger, and they could even form stronger formations.

One team feigned all attacks while the other team followed behind.

However, after Harlequin fired the Corrosive Arrows, a large number of monsters turned into liquid.

Then, Natasha quickly spawned among the monsters. In less than three seconds, hundreds of monsters turned into corpses.

Moreover, because Natasha's attributes had also awakened the poison attribute, the monsters quickly turned into liquid.

All that was left was a pile of treasure chests.

On the eighth day, these monsters were like cheetahs in their previous life, They rushed to the wooden wall very quickly but ended up cursed and poisoned.

So after the monsters were poisoned and cursed, they began to attack their companions.

The group easily won.

On the ninth day… On the tenth day…

...

On this day, the three of them stood on the wooden wall and saw many monsters rushing toward their territory in an orderly manner.

The three of them looked very serious because it was already the tenth day. The intelligence of these monsters was getting stronger and stronger.

Moreover, the leader of these monsters was also becoming more and more intelligent. The battle mode that he set up was actually quite effective.

If it weren't for the two heroes Natasha and Harlequin, they would have been conquered long ago.

However, the danger was often accompanied by rich rewards.

Now, the territory had been upgraded to level 4. The area of the territory was 2000 square meters. There were also six more defense towers, making a total of twelve.

There were three defense towers in every corner.

With this, they could directly protect the entire area.

Because they did not have to worry about mana crystals these days, these defense towers had also leveled up to level 4.

Their attack power was even more terrifying.

After that, there were five more Magic Fields, three Moon Wells, and another four walls.

The Altar, Barracks, and other buildings had all leveled up to level 4.

The steel female soldiers could also level up, so Lindsay had summoned another 25 of them.

Now, all the female soldiers had also leveled up to level 4.

As for the two heroines, they had also leveled up to level 4, and their combat strength was even more terrifying.

In addition, they had a good Lord who was willing to contribute to their growth, so they were definitely the strongest among the level 4 Gold Legendary heroes that were now available.

However, perhaps they had run out of luck. These few days, no matter how much Lindsay tried to summon a new hero, none would appear.

However, he summoned a lot of clothes. There were both male and female clothing, so the ladies did not have a lack of clothes to change into.

He also could not obtain experience points at the same rate as before. At this point, his territory was probably the one that had been developing the fastest amongst all the Lords.

"Today is already the tenth day. Everyone, don't let your guard down!"

"Yes!"

"Alright!"

Although Harlequin's tone was still lively, it was also extremely serious. After all, the monsters these few days seemed to be getting smarter and smarter.

If one looked carefully, they would see that there were many of them. However, the thick fog made it hard to gauge their current situation until they realized that so many monsters had arrived, being mistaken as the thick fog itself.

It was the same everywhere around them.

Judging from their slow pace, it seemed that they were not to be trifled with.

"My Lord, these monsters seem to be more intelligent than humans," Natasha said.

"Let's wait and see. I don't want to panic first," Lindsay said with a serious face.

He took out his magic staff and was ready to fight.

They didn't lack resources, so the three of them were all equipped to the gills.

All of them were fully equipped with white equipment.

Moreover, they also had plenty of other resources.

Lindsay had kept all of the treasure they collected, deciding that he would pawn them off later in the future.

Time slowly passed.

Suddenly, a strong wind blew and the monsters suddenly rushed over. In the middle of them, there was a monster holding a big knife that was screeching.

It seemed like it was commanding the monsters.

These monsters were all 2.5 meters tall and on their heads, they all had ferocious bull horns.

However, they were all big and bulky, similar to a bear.

What was this?

The three of them immediately cast their identification skills and saw the information of these monsters.

[Bull-headed Bear

Level: 10

Skills: Wind Cannon]

...

[Elite Bull-headed Bear

Level: 12

Skill: Wind Blade Breath, Bull-headed Sprint.]

...

Compared to the normal bull-headed bear, the elite bull-headed bear was more powerful and had an additional skill.

Boom, boom, boom!

The ground began to shake and bull-headed bears rushed over one by one.

In the blink of an eye, thousands of bull-headed bears rushed over.

It was dark all around, all converging to the territory with a terrifying force.

The territory was like an isolated island, ready to be drowned by the waves at any time.

Even though the territory had already reached the size 2,000 square meters, it still looked weak.

The strength of these monsters was definitely many times higher than the previous ones.

Even though they were all level 5 to 12, they could feel that their strength was even more terrifying.

Thus, with a wave of his hand, all the defense towers began to fire fiercely.

They attacked the monsters mercilessly.
