Return from the second dimension

When the last giant puppet in the Refuge of the Flash Gold was transported into the cave, the Holy Dragon City began to prepare for the promotion to the third-level building city.

Weapons and ammunition were transported to the city wall in large quantities, and all the soldiers in the outbuildings were conducting defensive drills to deal with possible emergencies.

This time Tang Zhen's actions were very big, and the number of monsters siege must not be small, so he must be fully prepared.

Although the atmosphere was very tense, the soldiers of the Holy Dragon City did not have a sense of fear.

Relying on the powerful weapons of the original world, whether it is a monster on land or in the air, Sacred Dragon City has the confidence to make it come and go.

Regarding this advancement of Loucheng, the happiest ones are actually those reserve residents, who did not expect to be able to obtain the qualifications of full-time residents so soon.

According to past experience, it takes at least ten years to change from a reserve resident to an official resident!

It would be an extremely long waiting process to become a prospective resident of a high-rise building city and want to become a regular one.

Some reserve residents have waited for a lifetime, but they have not crossed this hurdle!

Unexpectedly, after joining Sacred Dragon City, they can become full-time residents after only one month of being a reserve resident. How could they not be surprised!

The prospective residents who received the news were all caught in excitement.

They all looked forward to it, silently waiting for the moment when Loucheng was promoted.

They are full of confidence in whether the Holy Dragon City can withstand the monster's attack, and they think this is not a problem at all!

As the former residents of Loucheng, they are very familiar with the situation when monsters attack the city.

Although the siege monsters are strong, they can't resist the powerful defensive weapons of Holy Dragon City.

In the people's anxious waiting, the day of Saint Dragon City's promotion finally arrived.

All work in the Holy Dragon City ceased on this day, the residents were not allowed to act as required, and the walls were full of fully armed Holy Dragon City fighters.

Tang Zhen was dressed in an exquisite hand-made robe, and under the protection of a group of mighty and powerful Sacred Dragon City monks, Tang Zhen began the promotion ceremony of Loucheng.

The promotion of a second-level building city to a third-level building city requires the sacrifice of 10,000 third-level brains, which is equivalent to one million first-level brains!

The higher the level of a building city, the greater the number of brain beads sacrificed when he is promoted. When Tang Zhen is promoted to a fifth-level building city, the number of brain beads sacrificed will reach 100 million!

This is a terrifying number, without years of accumulation, don't even want to collect enough brains for sacrifice!

Tang Zhen threw 20,000 third-level brain beads into the altar and upgraded both the main city of the Holy Dragon City and the mother tree tower city at the same time!

In the eyes of the residents, huge changes have taken place in the main city and mother tree.

The size of the mother tree has more than doubled again, the huge tree body looks like a tall building, and the top of the canopy is actually a bit higher than the surrounding mountains!

Now the area covered by the mother tree has reached an area of ​​half a hectare, which can be described as covering the sky.

The promoted mother tree seemed extremely happy, countless brilliance rose from its branches and leaves, slowly flew into the air, and then burst like fireworks!

This is the mother tree using her own way to celebrate her promotion.

Compared to the mother tree's character that loves to show off, the promotion of the main city of Sacred Dragon City is much simpler.

In a hazy halo, the size of the main city of Holy Dragon City expanded rapidly, and it quickly became a giant!

The appearance of the main city still retains the original exterior decoration style, but the height has become sixty to seventy meters, like a super monster, entrenched in the Holy Dragon Valley.

After the promotion, the area of ​​the third-level building city has expanded countless times, and at the same time, countless new rooms have been added.

Tang Zhen also felt a mysterious power emanating from the Loucheng, the silent effect on every Loucheng residents, giving their physical fitness a little enhancement.

Tang Zhen knows that this is one of the so-called building city welfare, which can provide residents with a certain percentage of increase in physical attributes according to the level of the building city itself.

The higher the level of Loucheng, the more obvious this increase!

From now on, the main city of Sacred Dragon City is officially promoted to Level 3, and Mother Tree House City has also become a Level 3 Building City!

After upgrading the main city, Tang Zhen wants to build an auxiliary city!

Two brand-new altars have been placed on the square of the Holy Dragon City. Tang Zhen walked to the front and back and placed the two building foundation stones on it.

These two cornerstones are the cornerstone of the Loucheng Refuge of the Flash Gold Clan, and the cornerstone of the Loucheng of the Black Rock City.

After placing 20,000 first-class brain beads on the altar, Tang Zhen's consciousness immediately showed the past scenes of the two towers.

At the same time, two phantoms of the building city appeared in front of Tang Zhen, who was placed next to the main city in the Shenglong Valley.

Tang Zhen built the underground city under the Black Rock City, combining the two into one and quickly established.

Before long, a brand new building with an underground entrance appeared in the Holy Dragon Valley, looking solemn and solemn.

After silently glanced at the low, newly built auxiliary city, Tang Zhen shook his head and threw 20,000 second-level brain beads on the altar again!

The newly formed auxiliary city was immediately shrouded in light and became taller and taller.

With a big effort, Tang Zhen put in another 20,000 third-level brain balls to raise all the two auxiliary cities to third-level!

After the light dissipated, a white building one size smaller than the original Black Rock City was completely formed.

It's just that it is more beautiful and more energetic than Black Rock City!

This time the Loucheng upgrade, Tang Zhen consumed a total of 4.22 million brains, absolutely generous!

Fortunately, he has gained a lot during this period of time, even if he consumes so many brains, he still hasn't emptied his pockets!

Tang Zhen originally planned to upgrade the main building city directly to level 4, but when he thought of upgrading his mobile phone application, he finally resisted his desire to continue upgrading the building city.

What's more, after upgrading to the fourth-level building city, the monster's siege intensity will be greatly increased, plus the previous continuous upgrade accumulation, Tang Zhen can't imagine how many monsters will attack the city!

Compared with Loucheng, mobile phone applications are the foundation of his body. Tang Zhen can see clearly on this point.

The reason why he was able to flourish in the world of Loucheng was completely dependent on the anti-sky ability of the mobile phone application, otherwise he would never want to defend his hard-fought turf.

Although there is surplus in the brain, what is prepared for application upgrades cannot be easily misappropriated.

Of course, these are all things that are in the back, and what we have to do now is to deal with monsters siege!

Taking off his robes, Tang Zhen didn't check the four newly promoted castles at all, but immediately ran towards the walls.

It didn't take long before Tang Zhen came to the wall above the city wall.

More than two thousand holy dragon city fighters are waiting on the wall, all kinds of weapons are in a state of being ready to fire at any time.

Compared with before, the defensive power of Holy Dragon City has become stronger.

"What's the situation now, is there anything abnormal?"

Tang Zhen looked at Tyson with frowning brows and asked in a relaxed tone.

In fact, he also felt a little abnormal, as if something bad was about to happen.

Establishing two auxiliary cities, a total of six upgrades, in this extreme case, even if monsters are covered with gravel plains, it is very possible.

But relying on the weapons he possessed, Tang Zhen was so frightened!

But at this time, in front of the Holy Dragon City, no monster appeared, which in itself was a very strange thing.

Although the monsters in this area were almost killed by the corpse clan and Tang Zhen, there are still enough siege teams, and it is impossible for them to gather together like now.

Before I knew it, several hours passed.

Just as Tang Zhen's uneasy feeling grew stronger, a pitch-black whirlpool appeared out of thin air on the gravel plain not far away!

Sure enough, something happened!
