Not long after, Li Bingchu sent all the acquisition drawings to Lin Yuan.
After the drawings were in place, Lin Yuan naturally had to start construction of urban defense.
However, before starting construction, he still has to carefully choose.
After all, the urban defense buildings that can be built in a territory are also limited.
Therefore, in order to ensure the quality of urban defense buildings, you must choose appropriate architectural drawings.
Soon, Lin Yuan selected the first suitable architectural drawing.
Hide architectural drawings: The Holy Light Arrow Tower.
Using this architectural drawing, you can successfully build a hidden building - [Sacred Light Arrow Tower]!
If Lin Yuan remembers correctly, the price of this hidden drawing is quite expensive. Li Bingchu spent 70 million gold coins to buy it.
When the price of urban defense building drawings is generally not high, 70 million gold coins are considered a sky-high price.
However, the reason why Lin Yuan gave priority to the construction of the [Sacred Light Arrow Tower] was not because this drawing was so expensive.
It lies in the special effect of [Sacred Light Arrow Tower].
The special effect of this city defense building is that when it attacks necro creatures and abyss monsters, it will receive a 200% additional damage bonus!
You should know that the basic attack of the [Sacred Light Arrow Tower] is already very high.
If you count the additional damage bonus, it will undoubtedly become a nightmare for all abyss monsters!
To build the [Sacred Light Arrow Tower], it costs 10 million grain, 10 million wood, 10 million stone, and 5 million silver coins.
This resource is nothing to Lin Yuan.
He waved his hand and chose to start construction without hesitation.
Five minutes later, the [Sacred Light Arrow Tower] was built.
You should know that the biggest feature of urban defense buildings is that they have a short construction time, but they consume a lot of resources.
Fortunately, what Lin Yuan lacks the most is resources.
If you really lack resources, you can only buy it with money.
With the development of the game process, the resources in the hands of the lords gradually became more abundant.
The price of resources has become cheaper and cheaper.
Now, the exchange ratio of basic resources such as grain, wood, stone, and iron ore to gold coins has reached 100 to 1.
In other words, 10,000 gold coins can easily be exchanged for one million resources.
One hundred million resources, only one million gold coins.
For those who have special resource providers like Lin Yuan, the price will be even lower.
Therefore, Lin Yuan was not worried about the consumption of resources at all.
Looking at the tall arrow tower standing in the territory and emitting a breath of light, Lin Yuan couldn't help but feel satisfied flashed in his eyes.
This means that the first step in the construction of urban defense has been taken.
However, the newly established [Sacred Light Arrow Tower] is only one level and its attack power is not very high.
You should know that Lin Yuan’s current level of [City Lord’s Mansion] is level 7, so the level of city defense buildings can also be upgraded to level 7.
Therefore, Lin Yuan upgraded it directly without any hesitation.
[Sacred Light Arrow Tower] Upgrading from level 1 to level 2 requires 20 million grain, 20 million wood, 20 million stones, and 10 million silver coins.
If it continues to develop according to this ratio, the resources required will double for each level of upgrade.
Upgrading from level 6 to level 7 would require 640 million grain, 640 million wood, 640 million stones, and 320 million silver coins.
If it is exchanged for gold coins, it would be more than 30 million gold coins.
Just upgrading a city defense building requires such terrifying resources.
No wonder not many lords are willing to upgrade city defense buildings. The expenses of this thing are too high.
Moreover, if no one attacks the territory, the city defense building will not play any role at all, it is just decoration.
Now Lin Yuan has truly realized what it means to spend money like flowing water.
He originally thought that he had already accumulated 3.6 billion yuan through an auction, which was already a lot.
But now it seems that it is not enough?
No matter what, you must upgrade your city defense buildings.
If the money is really not enough, at worst, you can clean up a batch of treasures and go out.
Lin Yuan spent a whole day to finally upgrade the level of [Sacred Light Arrow Tower] to level seven.
After the level was upgraded to level 7, the appearance of [Sacred Light Arrow Tower] underwent earth-shaking changes!
I saw that the tower was covered with red and golden patterns, exuding a holy atmosphere of light!
On the arrow tower, ten archers wearing mitral armor were holding longbows emitting light, with sharp eyes as if they were hawk's eyes, patrolling around at all times to see if any enemies appeared.
Lin Yuan even used the Skeleton King to conduct an experiment and let the [Sacred Light Arrow Tower] attack it.
What Lin Yuan had never expected was that as a seventh-level army, the Skeleton King could not even catch an attack from the [Sacred Light Arrow Tower]!
I saw an arrow emitting a breath of light that instantly penetrated the Skeleton King's head!
The next second, a sacred flame ignited out of thin air on the body of the Skeleton King, and it burned it to ashes directly!
Looking at the scene in front of him, a shock flashed through Lin Yuan's eyes.
Even if the [Sacred Light Arrow Tower] has an additional damage bonus to undead creatures and abyss monsters, this damage is a bit outrageous, right?
The seventh-level army actually killed it in seconds with one arrow?
Sure enough, expensive things naturally make sense.
Although it took him a lot of resources to build the [Sacred Light Arrow Tower], Lin Yuan felt that these resources were worth it!
It won't take long before he can completely build his territory into a fortress like a copper wall!
…………
Time passes day by day.
During this period, Lin Yuan completely focused on territorial construction.
In just seven days, he built four seven-level city defense buildings in his territory!
Following this progress, Lin Yuan will be able to build all ten city defense buildings in at most for more than a week and upgrade them to level seven!
As for others, even if they can have Lin Yuan’s financial resources, they will definitely not be as efficient as Lin Yuan.
After all, Lin Yuan has the treasure [Divine Monument of Time] in his hand, which can reduce the construction and upgrade time of all buildings by half.
At least, Lin Yuan can lift the city defense building to the extreme before the abyss monster sieges the city.
After the city defense construction came to an end, Lin Yuan naturally prepared to start doing another equally important thing.
Without any hesitation, he directly called Li Bingchu's communication and asked straight to the point: "How did you collect the rare materials on the list?"
After hearing Lin Yuan's voice, Li Bingchu immediately answered: "The progress is quite smooth. Nearly 70% of it has been collected, and a total of about 400 million gold coins have been spent."
"Okay, not bad."
Lin Yuan said, "Then you can send these materials to me now."
After hearing this, Li Bingchu couldn't help but speak in surprise: "You want to use it now?"
"Well, I'll be able to use it later."
Lin Yuan nodded, chuckled and said, "If you are interested, you can come with me."
