Seeing the hidden hint, I dug out the masonry treasure chest at the beginning!

[[Elite] Archer Puppet Battalion (Tier [-] Peak)]

[[Power] Tier 0 puppet archer: 10/150 ([-] iron ore can be used to make an archer)]

Su Ming couldn't wait to deploy the advanced puppet bow and arrow barracks.

Immediately, the frowning brows relaxed.

He originally wanted to bless the imprint of power on the flame cannon.

However, the flame turret is so powerful that a small imprint of power will have no effect at all.

After seeing the hidden hint, he decisively chose to give up.

That's what happened now.

A mark of strength not only raised the bow and arrow barracks to the elite level, but even raised it directly from the middle level of the second level to the peak level of the second level.

The improvement of these two points will directly turn the tasteless tasteless chicken ribs into chicken legs.

It is no exaggeration, compared to before, the strength of the elite archers at the peak of the second order has improved too much.

After all, even when encountering a treacherous tide, there are only a few high-quality treacherous ones, and most of them are of ordinary quality.

With these elite archers at the peak of the second level, they can completely shoot when facing the common monsters below the third level.

This has greatly improved the defense capabilities of the entire base city.

After the upgrade, the bow and arrow barracks consumed [-] more iron ore when making bow and arrow puppets.

That's the only downside.

Of course, this didn't have much impact on Su Ming.

After all, he owns a vein of iron ore. There is no shortage of iron ore, and it is even increasing.

If he doesn't use it anymore, he still thinks it's taking up space if he stays in the base!
"Robot, put in [-] pieces of iron ore and start making puppet archers."

After Su Ming's voice fell, the mining robots in the mining camp stopped immediately.

Then he held pieces of iron ore and slowly put them one piece after another into the furnace of the barracks.

With the iron ore in place, the barracks made bow and arrow puppets very quickly.

Soon, ten bow and arrow puppets stood neatly in front of Su Ming. They were all made of black iron, and their whole bodies were covered with armor made of black iron.

In his right hand he holds a giant steel bow.

On the bow, there is a red power symbol engraved.

[[Elite] Puppet Archer (Tier [-] Peak)]

[Attribute: Strength]

[Range: 100 meters]

[Serial shooting: three arrows per second, serial shooting. 】

[Strength increase: double the strength within ten seconds, and double the attack distance]

"It's not bad, you go to each post separately to stand guard!"

Su Ming nodded in satisfaction, and then distributed it to each city wall.

Elite quality is indeed much stronger than ordinary quality archers, at least in the face of treacherous tides, the role of elites is much greater.

Most of the treacherous tide is still dominated by ordinary treachery. If the archer is only of ordinary quality, then it is really difficult to shoot when facing the second-order ordinary treachery.

But
Now, the archers have all been promoted to the peak of the second order, and they are still of elite quality.

Then, ordinary second-order treachery can basically kill it.

It can even be said that the ordinary treachery below the second-order peak can be killed in seconds, and the lethality is really incomparable.

One flame cannon, ten puppet archers.

Su Ming arranged everything in place, with a satisfied smile on his face.

"It's like that! But it's not enough!"

Su Ming squinted his eyes. The hidden reminder he saw before told him that in this polar night canyon, he would be subjected to extremely terrifying and strange tides.

Immediately, he set his sights on the previous position again.

[Hidden hint: The Polar Night Canyon is narrow, and the treacherous tide will be stronger than ever. 】

[Hidden hint: Keep working hard, your strength is still lacking. 】

Two hidden prompts popped up, and Su Ming fell into deep thought again.

Such strength is not enough?
How strong will this strange tide be?

So...can the other chosen ones really pass this experience?
My current strength has left them far behind, and even my strength is still lacking.

No way?
After this strange tide comes, I will be the only one left in the entire underworld, right?
There are many thoughts in Su Ming's mind. He originally thought that his overall strength has become so strong now.

Moreover, his own base city has also built so many means of attack and defense.

Unexpectedly, it was still impossible to survive this crisis safely.

Um?By the way, the blueprint of the third-tier city wall!
Looking at the hidden hint in front of him, Su Ming suddenly thought that after breaking through to the second level, he also obtained a blueprint for upgrading the city wall!
I have been building forts and archery barracks before, but I haven't come to check them out yet!
Thinking of this, he quickly took it out of the storage ring, and an attribute panel unfolded.

[Third-tier city wall blueprint]

[Third-order soul orb: 0/1]

[Third-order earth attribute spar: 0/1]

[Third-stage evolution spar: 0/1]

【Iron Ore: 0/1500】

Tier three!

Sure enough, if you want to advance to the third-order level, you must consume third-order materials.

"Continue! Get your level up to the peak of Tier [-] first! Then go deeper and hunt Tier [-] treacherous to obtain Tier [-] Soul Orbs, Attribute Crystals, and Evolution Crystals!"

Su Ming pondered for a while, and the fighting spirit in his eyes was rekindled.

Since the current strength is not enough, then work hard to improve the strength.

He has just been promoted to the lower level of the second tier now, and there is still a lot of room for improvement.

You know, compared to the second-order peak and the second-order lower, they are not at the same level at all.

Then let's raise your strength to the peak of the second order first!
If the strength is still insufficient at that time, then continue to move forward, break through the middle of the polar night canyon, and go to explore further!
Hunt and kill the third-order treachery as much as possible, so that the city wall can be upgraded and have more self-protection ability!
Su Ming thought about it without any hesitation.

Immediately, with his blood, he stepped into the wilderness area again, fighting towards the middle of the Polar Night Canyon.

This time, with the flame turret and ten puppet archers, Su Ming didn't worry much about the safety of the base city.

At this moment, in the middle of the Polar Night Canyon.

The huge rock blocking the way kept shaking, and the light and shadow on it staggered, disappearing for a while, and appearing for a while.

hum~
Immediately afterwards, the mountain rock began to twist, and there was a dull sound of intertwining bones.

Ka Ka Ka ~
Ka Ka Ka ~
As the phantom of the mountain and rock continued to distort, the dull voice became more and more obvious, constantly echoing in the space.

As the dull voice emerged, the skeleton warriors around the phantom of the rock fell to their knees facing the direction of the rock.

"Kakaka~"

"Kakaka~"

"Kakaka~"

Their mandibles opened and closed, as if they were talking about something, but the interlacing of bones was almost the same as that dull voice.

As they chanted, they fell to their knees and kowtowed continuously.

At this time, a large group of skeleton warriors around the phantom mountain stone knelt down, and the sound of crackling could be heard endlessly.

Their attitudes are extremely sincere, as if there is an existence in the phantom that they respect and fear.

"Ka Ka Ka ~ blood and flesh. The taste of flesh and blood"
