286 Upgrade to a level 3 building
When the last giant puppet in the glittergold race's sanctuary was transported into the cave, Holy Dragon City began to prepare for the upgrade to a level 3 building.
A large amount of weapons and ammunition were being transported to the city wall. All the soldiers in the city were doing their defense exercises to deal with any unexpected situations.
This time, Tang Zhen's actions were very big. The number of monsters attacking the city would definitely not be small. Therefore, they had to be fully prepared.
Although the atmosphere was tense, the Holy Dragon city's soldiers did not have a trace of fear.
Relying on their powerful weapons from the original world, the Holy Dragon City was confident that they would not be able to return to the land or air monsters.
The ones who were the happiest about the tower's advancement were actually the reserve residents. They didn't expect to be able to obtain the qualifications of official residents so quickly.
According to past experience, it would take at least ten years to become an official resident from a reserve resident!
If one became a reserve resident of a high-level city and wanted to become a full-time employee, it would be an extremely long waiting process.
Some reserve residents had waited for their entire lives but still could not cross this hurdle!
Who would have thought that after joining the Holy Dragon City, they could become official residents after being reserve residents for a month? how could they not be surprised?
The reserve residents who received the news were all in a state of excitement.
They were all looking forward to Lou Cheng's advancement.
They were all confident that the Holy Dragon City could resist the monster siege. They thought that it was not a problem at all!
As former residents of the city, they were very familiar with the situation when the monsters attacked the city.
Although the monsters attacking the city were strong, they could not withstand the Holy Dragon city's powerful defensive weapons.
As the people anxiously waited, the day of Holy Dragon city's advancement finally arrived.
On this day, all work in the Holy Dragon City stopped. The residents were not allowed to act on their own accord as per the requirements. The city walls were filled with fully armed Holy Dragon City soldiers.
Tang Zhen was dressed in an exquisitely hand-made robe. Under the protection of a group of mighty and strong Holy Dragon City cultivators, Tang Zhen began the Lou city's advancement ceremony.
To upgrade a level 2 City building to a level 3 city building, he would need to sacrifice ten thousand Level 3 brain pearls, which was equivalent to one million Level 1 brain pearls!
The higher the level of the tower, the more brain beads needed to be sacrificed. By the time Tang Zhen advanced to a level 5 tower, the number of brain beads needed to be sacrificed would reach 100 million!
This was a terrifying number. Without years of accumulation, it was impossible to gather enough brains to sacrifice!
Tang Zhen threw 20000 Level 3 brain beads into the altar, upgrading the Holy Dragon City and the mother tree City at the same time!
In the eyes of the residents, the main city and the mother tree had undergone tremendous changes.
The mother tree's body had doubled in size once again, its huge trunk looked like a skyscraper, the top of the tree crown was even higher than the surrounding mountains!
The area covered by the mother tree had now reached half a hectare, and it could be said to have blotted out the sun.
The mother tree seemed to be extremely happy after its advancement. Countless radiances rose from its branches and leaves, slowly flying into the air, and then exploded like fireworks!
This was the mother tree's own way of celebrating its advancement in rank.
Compared to the mother tree's boastful nature, the Holy Dragon city's main city promotion was much simpler.
In a hazy Halo, the Holy Dragon city's main city's size rapidly expanded, quickly becoming a huge object!
The exterior of the main city still retained its original external decoration style, but its height had been increased to sixty to seventy meters. It was as if a Super Monster had occupied the Holy Dragon Valley.
After the upgrade, the area of the level 3 building had expanded by countless times, and at the same time, there were countless new rooms.
Tang Zhen could also feel a mysterious power being emitted from the building. It silently affected every resident of the building, strengthening their physical fitness.
Tang Zhen knew that this was one of the so-called benefits of the building. According to the level of the building, it could provide a certain amount of physical attribute enhancement to the residents.
The higher Lou Cheng's level was, the more obvious the increase was!
From now on, the Holy Dragon city's main city had officially been upgraded to Level 3, and the mother tree's city had also become a level 3 city!
After upgrading the main city, Tang Zhen still had to build an auxiliary city!
Two brand new altars were already placed in the Holy Dragon city's Square. Tang Zhen walked in front of them and placed two tower cornerstones on them.
These two cornerstones were the glittergold race's sanctuary's cornerstone and the Black Rock City's cornerstone.
After placing the 20000 Level 1 brain beads on the altar, the past scenes of The Two Towers immediately appeared in Tang Zhen's consciousness.
At the same time, the illusionary image of two towers appeared in front of Tang Zhen. He placed them next to the main city in the sacred Dragon Valley.
Tang Zhen had built the underground city below Black Rock City. The two of them merged into one and were quickly built.
It didn't take long for a new building with an underground entrance to appear in the sacred Dragon Valley. It appeared solemn and respectful.
After silently glancing at the low and newly built auxiliary city, Tang Zhen shook his head and once again threw 20000 Level 2 brain beads into the altar!
The auxiliary city that had just been formed was immediately shrouded in light and became taller and taller.
In a spurt of energy, Tang Zhen invested another 20000 Level 3 brain beads, upgrading both auxiliary cities to Level 3!
After the light faded, a white building that was one size smaller than the original Black Rock City was completely formed.
However, it was even more beautiful than Black Rock City, and it was even more lively!
This time, Tang Zhen had used a total of 4.22 million brain beads to upgrade the building. It was definitely a big deal!
Fortunately, he had gained a lot during this period of time. Even though he had consumed so many brains, he still did not empty his wallet!
Tang Zhen originally planned to upgrade the main building to Level 4, but when he thought about how he still had to upgrade his mobile application, he finally resisted the desire to continue upgrading the building.
Moreover, after the city was upgraded to Level 4, the strength of the monsters 'attacks would increase greatly. In addition to the accumulation of the previous continuous upgrades, Tang Zhen did not dare to imagine how many monsters would attack the city!
Compared to Lou Cheng, mobile applications were the foundation of his career. Tang Zhen was very clear about which was more important.
The reason why he was able to do so well in the loucheng world was entirely because of the nature-defying abilities of the mobile application. Otherwise, he could forget about defending the territory that he had fought so hard to obtain.
Although he still had excess brain matter, he had prepared it for the use and upgrade, so he could not simply use it.
Of course, these were all matters for later. The current task was to deal with the monster siege!
After taking off his long robe, Tang Zhen did not even bother to check on the four newly upgraded towers. Instead, he immediately ran towards the city walls.
not long after, tang zhen arrived at the top of the city wall.
More than two thousand Holy Dragon City soldiers were standing by on the city walls, all sorts of weapons ready to fire.
Compared to the past, the Holy Dragon city's defensive forces had become stronger.
what's the situation now? did anything unusual happen? "
Tang Zhen looked at Tai Seng, who was frowning, and asked in a relaxed tone.
In fact, he had also felt a trace of abnormality, as if something bad was about to happen.
The construction of two auxiliary cities would require a total of six levels. Under such extreme circumstances, it was highly possible that the entire gravel plain would be filled with monsters.
However, Tang Zhen's heart was filled with fear by relying on the weapon he possessed!
However, not a single monster had appeared in front of Holy Dragon City. This in itself was a very strange thing.
Although the monsters in this area were almost all killed by the undead race and Tang Zhen, it was more or less enough to form a siege team. It was impossible for not a single monster to gather like now.
A few hours passed by without him realizing it.
Just as the uneasiness in Tang Zhen's heart was growing stronger, a pitch-black Vortex appeared out of thin air on the gravel plain not far away!
As expected, an unforeseen event had happened!
