After the last giant puppet in the Jinjin Clan's refuge was transported into the cave, Holy Dragon City began to prepare for promotion to the third-level city.
Weapons and ammunition were transported to the city wall in large quantities, and all Loucheng soldiers were conducting defense drills to deal with possible emergencies.
This time Tang Zhen will make a big move, and the number of monsters attacking the city will definitely not be small, so be fully prepared.
Although the atmosphere was tense, the soldiers of Holy Dragon City did not feel any fear.
Relying on the powerful weapons of the original world, whether it is monsters on the ground or in the air, Shenglongcheng is confident that they will never come back.
The happiest people about this advancement of the building city are actually the preparatory residents. They did not expect to be able to obtain the qualifications of formal residents so soon.
According to past experience, if you want to change from a preliminary resident to a formal resident, you have to wait at least ten years!
If you become a preparatory resident of a high-end building city and want to become a full-time resident, it will be an extremely long waiting process.
Some preparatory residents have waited their entire lives but have never crossed this hurdle!
They didn't expect that after joining Holy Dragon City, they could become official residents after only one month of being a preliminary resident. How could they not be surprised!
After receiving the news, everyone among the preparatory residents fell into excitement.
They all looked forward to it, silently waiting for the moment when Loucheng would be promoted.
They are full of confidence in whether Holy Dragon City can withstand the monster siege, thinking that this is not a problem at all!
As former residents of Loucheng, they all know very well what happens when monsters attack the city.
Although the monsters attacking the city are strong, they cannot withstand the powerful defensive weapons of Holy Dragon City.
While people were waiting anxiously, the day for Holy Dragon City to be promoted finally arrived.
On this day, all work in Holy Dragon City was stopped. Residents were not allowed to move without permission as required, and the city walls were filled with fully armed Holy Dragon City soldiers.
Tang Zhen was wearing an exquisite handmade robe. Under the protection of a group of mighty and powerful Holy Dragon City monks, Tang Zhen began the promotion ceremony of Lou City.
To promote a second-level building city to a third-level building city, you need to sacrifice 10,000 third-level brain beads, which is equivalent to one million first-level brain beads!
The higher the level of Lou Cheng, the greater the number of brain beads sacrificed during promotion. When Tang Zhen is promoted to the fifth level of Lou Cheng, the number of brain beads sacrificed will reach 100 million!
This is a terrifying number. Without years of accumulation, there is no way you can collect enough brains to sacrifice!
Tang Zhen put 20,000 level-3 brain beads into the altar and upgraded the main city of Shenglong City and the Mother Tree Tower City at the same time!
In the eyes of the residents, the main city and the mother tree have undergone tremendous changes.
The size of the mother tree has more than doubled again. The huge tree body looks like a high-rise building, and the top of the tree crown is even higher than the surrounding peaks!
Now the area covered by the mother tree has reached half a hectare, which can be said to block out the sky and the sun.
The promoted mother tree seemed extremely joyful, with countless brilliance rising from its branches and leaves, slowly flying into the air, and then exploding like fireworks!
This is the mother tree using its own way to celebrate its promotion.
Compared to Mother Tree's personality that loves to show off, the promotion in the main city of Holy Dragon City seems much more down-to-earth.
In a hazy halo, the main city of Shenglong City expanded rapidly and soon became a behemoth!
The appearance of the main city still retains the original exterior decoration style, but the height has increased to sixty or seventy meters, as if it were a super monster entrenched in the Holy Dragon Valley.
After the promotion, the area of the third-level building city has been expanded countless times, and countless new rooms have also been added.
Tang Zhen also felt a mysterious power emanating from the building city, silently affecting every resident of the building city, enhancing their physical fitness.
Tang Zhen knew that this was one of the so-called benefits of building city, which could provide residents with a certain proportion of physical attribute increase according to the level of building city itself.
The higher the level of the building city, the more obvious this increase will be!
From now on, the main city of Shenglong City has been officially promoted to the third level, and the Mother Tree Tower City has also become a third-level tower city!
After upgrading the main city, Tang Zhen will also build a auxiliary city!
Two brand-new altars have been placed in the square of Shenglong City. Tang Zhen walked up to them and placed the two cornerstones of the city.
These two cornerstones are the foundation stone of the Golden Flash Clan's refuge and the foundation stone of Black Rock City.
After placing 20,000 first-level brain beads on the altar, the past scenes of the two tower cities immediately appeared in Tang Zhen's consciousness.
At the same time, two phantom buildings appeared in front of Tang Zhen's eyes, and he placed them next to the main city in the Holy Dragon Valley.
Tang Zhen built the underground city under Black Rock City, and the two merged into one and were quickly built.
Not long after, a brand new building with an underground entrance appeared in the Holy Dragon Valley, looking solemn and solemn.
After silently glancing at the low new auxiliary city, Tang Zhen shook his head and threw 20,000 second-level brain beads onto the altar again!
The newly formed auxiliary city was immediately shrouded in light and became taller and taller.
In one go, Tang Zhen invested another 20,000 level 3 brain beads, upgrading all these two auxiliary cities to level 3!
After the light dissipated, a white building one size smaller than the original Black Rock City was completely formed.
It's just that it's more beautiful and more vibrant than Black Rock City!
This time, Tang Zhen spent a total of 4.22 million brain beads to upgrade the building city, which was absolutely generous!
Fortunately, he has gained a lot during this period. Even though he has consumed so many brains, he still has not drained his pocket!
Tang Zhen originally planned to directly upgrade the main building city to level four, but when he thought about upgrading the mobile application, he finally resisted the desire to continue upgrading the building city.
What's more, after upgrading to the fourth level of the city, the intensity of monster siege will be greatly increased. Coupled with the accumulation of previous continuous upgrades, Tang Zhen couldn't imagine how many monsters would attack the city!
Compared with Lou Cheng, mobile phone applications are the foundation of his life. Tang Zhen sees this clearly.
The reason why he was able to prosper in the Loucheng world was entirely due to the incredible ability of mobile phone applications, otherwise he would never have thought of holding on to the territory he had worked so hard to gain.
Although there is still plenty of brain power, it is prepared for application upgrades and cannot be misappropriated easily.
Of course, these are all things that come later. What we need to do now is to deal with the monster siege!
Taking off his robe, Tang Zhen didn't even check the newly promoted four buildings, but immediately ran towards the city wall.
Not long after, Tang Zhen came to the top of the city wall.
More than two thousand Holy Dragon City soldiers are waiting on the city wall, and all kinds of weapons are ready to fire at any time.
Compared with before, the defensive force of Shenglong City has become stronger.
"How is the situation now? Is there anything abnormal?"
Tang Zhen looked at Tyson, who was frowning, and asked in a relaxed tone.
In fact, he also felt something abnormal, as if something bad was about to happen.
Establishing two auxiliary cities and upgrading them a total of six times. In this extreme case, it is very possible for monsters to cover the gravel plain.
But with the weapons he had, Tang Zhen felt so dirty and fearful!
But at this time, not a single monster appeared in front of the Holy Dragon City, which was a very strange thing in itself.
Although almost all the monsters in this area were killed by the Zombie Clan and Tang Zhen, they could still assemble an siege team, and it was impossible not to have any monsters gather like now.
Before I knew it, several hours passed.
Just as the uneasiness in Tang Zhen's heart became more intense, a dark vortex appeared out of thin air on the gravel plain not far away!
Sure enough, something unexpected happened! (To be continued.)
