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

The third level superior!Rare quality!
Looking at this city wall covered in khaki scale armor with silver lines outlined on it, Su Ming couldn't help but feel ecstatic.

Compared with the flame fort, the defense of this city wall is more important.

After all, this is the last line of defense, and it is the foundation of the base city.

Even if the flame turret can't suppress the enemy's progress, there is still a city wall to cover.

If the walls are broken, then everything is over.

Although Su Ming is very confident, he is also very clear that if the treacherous tide is strong enough to easily overcome the suppression of the flame fort, it will eventually be able to break through the city wall.

At that time, it will be impossible to deal with it alone.

Su Ming is not a fool, he is naturally very clear about this.

That's why he decided to stay behind even though he knew through the hidden reminder that the Polar Night Canyon was extremely dangerous.

Because, he can't escape at all!
Without the defense of the base city, it would be impossible to resist the entire treacherous tide with just his own strength!
At least, in a short period of time, his strength is far from enough.

Today, the defensive city wall has not only been upgraded to the third tier, but has also become a rare quality.

How could he not be happy about it?

After all, this thing can greatly improve one's survivability!
The original dark city wall was covered with a layer of khaki scales, which made it look a little thicker. The flame fortress and bow and arrow puppet soldiers above the city wall were all in one piece.

Especially on the dark longbows of those bow and arrow puppets, wisps of light yellow energy are intertwined, which looks a little thicker.

Is this... a function of the rare city walls?

Immediately, Su Ming directly focused his gaze on the earth-colored city wall, and then softly called: "Open the panel!"

Swish!
[[Rare] Burgundy Silver Wall (Tier [-] Superior)]

[Guardian of Gentu (Passive): All units in contact with the city wall are protected by it and enjoy the same defense. 】

When this prompt popped up, Su Ming opened his mouth involuntarily.

Gentu guardian!

Although it is only a passive skill, the effect of this skill is really amazing.

It is said that there is specialization in the art industry, what is the most important attribute of this city wall?
What else could it be but defense?

The third-tier upper rare city wall, although it does not have the slightest attack power.

But in terms of defense, even Tier [-] epic treachery can't break through!
Of course, Shifting Tides cannot be viewed through conventional eyes.

If it can be called a tide, then it must be on a certain scale. Under the continuous attacks of a large number of treacherous, even the hardest city wall will be worn out a little bit.

A drop of water pierces a stone, and an iron pestle rubs against a needle. This is what is being said.

However, Su Ming's base does not only have the city wall as a passive defense barrier.

He also has an epic-quality flame turret, an elite-quality bow and arrow puppet, and his epic psychic.

If these treacherous tides want to touch the city wall, they must go through the baptism of forts and archers.

Even if they pass by luck, there is Su Ming, the epic psychic, waiting for them.

Therefore, it is really not easy for them to touch the city wall.

Of course.
If they really broke through the checkpoints and successfully touched the city wall.

However, it is obviously not easy to break through the city wall.

Unless the opponent can kill the flame turret with extreme firepower output!

This is also a question that Su Ming is more worried about.

After all, this flame turret is the most powerful attacking unit in the base. If it is destroyed, the firepower of the entire base will be directly halved.

This is no exaggeration!

Therefore, even if he has a third-order 'power imprint' in his hand now, he is in a hurry to use it.

After all, in the current situation, this third-order mark can maximize its benefits when used on an epic-level flame cannon.

But the Flame Fort is just an attacking unit, not defensive at all.

If you put all your treasures on it, once the fort is destroyed, the whole basket will be empty.

Really wait until that time, Su Ming really can't guarantee whether he can successfully survive the treacherous tide.

After all, the red 'extremely dangerous' warning on this map is very eye-catching!

However, it is different now.

The [Gentu Silver Wall] that evolved to the third level really gave him too many surprises.

The original city wall was like poured steel. It was useless except for being strong. Even the city gate was separated from it, which became the weak point of the entire city wall defense.

But today's [Gentu Silver Wall] integrates everything into a whole.

Its passive is too perverted, as long as it is in contact with the city wall and the base unit can enjoy the same defense.

There is no doubt that this passive is a magical skill!

Especially when it becomes a 'city wall' that focuses on defense, it is a magic skill among magic skills.

With this passivity, there is no need to worry about the defense of the Flame Cannon.

After all, it shared the defense of the city walls.

In other words, as long as the city wall does not collapse, the Flame Fort will not be destroyed.

What do you want to say that the city wall has collapsed?
This... the city walls have collapsed, so what's the use of leaving only the forts?

The opponent was able to push down such a powerful city wall. How many attacks can you, a defenseless fort, withstand?
This is a meaningless question!

Su Ming already understood in his heart that the city wall is the foundation!
The fort above the city wall is based on the existence of the foundation. The two rely on each other, one attack and one defense, complement each other.

Now, after the city wall is upgraded, the offense and defense are directly integrated, and the offense and defense are integrated!
In this way, all previous worries will no longer exist.

Mark of Power + Flame Turret!

What kind of sparks will they rub against each other?
Su Ming didn't think too much, he directly took out the third-order power imprint, and came directly to the top of the city wall in a dodge.

However, Su Ming is not a 'unit building', so the Nagentu Guardian didn't take effect on Su Ming.

Of course, these are not his concerns.

All he can see now is the 'flame fortress', which is his most powerful attacking weapon.

Immediately afterwards, Su Ming did not hesitate at all.

He directly placed the imprint of power in his hand in front of the flame cannon.

Immediately, red fluorescent lights shone on the imprint, and then slowly moved towards the flame fort.

"Ding! Do you want to inlay a third-order power imprint on the flame cannon?"

"Ding! Warm reminder, the fort will be promoted to the third level if it is successfully inlaid, and it will become damaged if it fails, and its power will fall back to the lower level of the second level."

The sound of the system echoed in the sky, and the power imprint in Su Ming's hand became more and more fluorescent.

Immediately afterwards, under the shocked eyes of all the audience watching the live broadcast, Su Ming directly chose the inlay.

What is he doing?
This...this courage is too big!

Undoubtedly, looking at Su Ming's choice, this is the subconscious thought of most people.
