The next moment, Zhang Xiaoming suddenly reacted, when this tower defense building is upgraded to level four, it can be advanced to a new building!

You only need to advance to a new building to increase your unlock level.

As the unlock level increases, you have a new tent purchase limit.

I didn't dare to delay, and immediately started to build and upgrade the wooden fence.

As the wooden fence was raised to level four, a selection prompt appeared in front of Zhang Xiaoming's eyes again.

[Hint]: "Level 3 Wooden Fence can choose to advance to an Iron Fence, or continue to upgrade to Level 4 Wooden Fence, please make a choice within a minute, otherwise the system will randomly choose." ”

Without hesitation, he directly chose to advance to become an iron fence.

With the successful establishment of the iron fence, the system finally sent Zhang Xiaoming's long-awaited unlock level improvement prompt.

[System]: "Ding! Congratulations on the unlocking level has been raised to Level 2, the building placement slot has been increased by one square, the maximum number of all building cards has been increased by 10, the resource limit has been increased by three times, and new cards have been successfully unlocked, which can be viewed and purchased in the card store. ”

"Ding! Due to the unfinished apprenticeship of the tower defense division, the tower defense division level upgrade failed! ”

"I'll it! The number of tickets is increased by ten. ”

Zhang Xiaoming was overjoyed.

At this moment, he didn't have time to enjoy this joy, and if he didn't quickly solve the problem of the population limit, his soldiers would be finished.

I didn't dare to delay, I was busy opening the card store, directly purchased ten tent cards, and immediately chose to build.

Seeing a large number of newly built tents in front of him, Zhang Xiaoming was completely relieved, and the problem of the population ceiling was finally successfully solved.

Then, it was another synthesis, and finally we got a three-level tent, a tent.

At this moment, Zhang Xiaoming had time to check the new cards unlocked.

As before, there are still five new building cards unlocked: Houses, Iron Fences, Rapid-Fire Towers, Ballista Towers, and Lumberyards.

After a slight glance at the introduction of the three new card buildings, he found that the rapid-fire tower should be an advanced version of the arrow tower, but the crossbow tower was a reduced version of the armor-piercing crossbow tower, which made Zhang Xiaoming a little puzzled.

As for the lumberyard, it is a new tower defense building, there is logging technology and carpentry technology to study, and I feel that the main role should be to process wood, which is a bit of a chicken rib for me now.

Now that you have the new building card and know that the building can be advanced when you upgrade to level 4, of course, you have to experiment with the advanced versions of various buildings right away.

Coming to the pass non-stop, he was the first to try the advanced version of the ground thorn and obtained a metal ground thorn.

Then there is the arrow tower, what I never expected is that the two advanced directions of the arrow tower are actually the rapid-fire tower and the crossbow tower.

These two tower defense building cards are already available, so they naturally chose to upgrade to a fourth-level arrow tower.

Then, there were the slingstones, watchtowers, stone walls, and magic towers, all of which were all advanced.

As for the Armor-Piercing Ballista Tower, it was sad that no advanced option appeared.

After returning to the shelter camp, Zhang Xiaoming purchased and built 20 more houses in one go.

In this way, people don't have to waste time on construction.

Now that they have a new home, they don't have to work hard to build it, and the survivors are all happy to congratulate each other.

However, before they could rejoice, the peasants took on a new task of clearing the fields.

The survivors, who were originally happy, immediately complained, but under the threat of the soldiers, they dared to be angry and did not dare to speak, so they had to work honestly.

With a house, a population ceiling, and a strong ability, Zhang Xiaoming, who is full of self-confidence, has the plan to go out to make waves.

Before that, he tried to advance to a barracks to see if he could unlock new classes.

Sure enough, it didn't disappoint, and when you were promoted to the fourth-level barracks, there was indeed an advanced choice.

But what is confusing is that there are multiple advanced options.

"Junior infantry battalion! Junior artillery battalion! Junior cavalry battalion! Why don't you just advance to a junior barracks? Isn't it interesting to do more? ”

Zhang Xiaoming couldn't help but complain.

After thinking about it for a long time, he finally chose to advance to become a junior artillery battalion.

Ordinary combat units, with infantry and musketeers, are enough for the time being, and mobile units with cavalry, which are also enough for the time being.

Then, what is most lacking now is a powerful firepower output, and the strongest firepower output is undoubtedly artillery.

As soon as the artillery battalion was successfully established, it immediately checked the introduction.

【Artillery Battalion (Elementary)】

Defense: 5

Special Skills: Musketeer, Artilleryman, Rapid Shooting (Beginner), Charged Shooting (Beginner)

Durability: 50/50

Introduction: The ordinary product of the combination of mechanism and alchemy, except for training some soldiers with ordinary combat power, is almost useless, and it is recommended to recycle it at a low price.

"Huh? Just one more artillery and two skill studies? And castrated other types of ordinary troops? ”

Zhang Xiaoming was a little speechless.

After thinking about it a little, he directly waved his hand and trained ten artillerymen.

In the next moment, ten burly men with a thick barrel on their shoulders, two meters five or six tall, as strong as a bull, stepped in front of Zhang Xiaoming with heavy and steady steps, and shouted angrily: "The soldiers of the artillery battalion meet the city lord!" ”

"Excuse me!"

Zhang Xiaoming nodded with satisfaction.

Then, ten more cavalrymen and five peasants were trained.

After looking at the remaining one hundred and twenty-two energy points, he finally trained two more cavalrymen.

After the explosion was over and everyone was dismissed, Zhang Xiaoming immediately returned to the camp alone, wanting to try the specific changes in his body.

After some trying, I was surprised to find that not only did my strength increase, but my body was also faster and stronger, and I had not yet discovered other abilities.

"Ugh! It seems that he has become an apprentice magician, but how do you release the magic? I don't think I know! ”

After trying for a long time, Zhang Xiaoming, who couldn't release the slightest magic shadow, was very entangled.

"Forget it, let's go and ask Master Karin!"

Muttered to himself, and walked out of the tent.

Came to Karin Victor's door, tidied up her clothes a little, and then asked softly, "Is Master Karin free?" ”

"Lord of the City, please come in."

Karin Viktors' elegant voice rang out from inside the room.

However, when you listen closely, the voice seems a little weak.

After Zhang Xiaoming gently pushed the door in, he said with concern: "Master Karin, are you okay?" ”

"No problem."

Karin Victor smiled charmingly.

"Master Karin! Your face is a little wrong, is there something wrong with your cultivation? Do you need someone to help you take a look? ”

Zhang Xiaoming found that Karin Victor's face was a little pale, and he was faintly worried in his heart.
