He then began to upgrade the Thorn Fence.
First, he improved its quality.
The quality upgrade of the Thorn Fence only required crystal cores, which were nothing to him.
When he was on the Elf Forest Continent, he had acquired a considerable number of one-star to six-star wood-attribute crystal cores.
Consuming a large amount of three-star wood-attribute crystal cores, the quality of the Thorn Fence was finally raised to R quality. Next, a thousand five-star wood-attribute crystal cores would be needed to upgrade its quality to RR.
He had a large quantity of wood-attribute crystal cores. After consuming one thousand five-star wood-attribute crystal cores, he upgraded the quality of the Thorn Fence to RR.
Finally, five thousand six-star wood-attribute crystal cores were needed to upgrade the quality of the Thorn Fence to its maximum level.
After he consumed them, the quality of the Thorn Fence was finally upgraded to RRR.
He then started to increase the level of the Thorn Fence.
Upgrading this building required spirit coins and wood-attribute crystal cores.
Territory prompt: "Consuming twenty thousand spirit coins and ten one-star wood-attribute crystal cores, the Thorn Fence level has been upgraded to 21."
...
Territory prompt: "Consuming one hundred thousand spirit coins and one hundred two-star wood-attribute crystal cores, the Thorn Fence level has been upgraded to 30."
...
Territory prompt: "Consuming two hundred thousand spirit coins and three hundred three-star wood-attribute crystal cores, the Thorn Fence level has been upgraded to 40."
...
...
Territory prompt: "Consuming two million spirit coins and five hundred five-star wood-attribute crystal cores, the Thorn City Wall level has been upgraded to 60."
After the Thorn Fence's level was upgraded to fifty, its name changed to Thorn City Wall.
He had also upgraded the level of the Thorn City Wall to sixty. The entire structure not only resembled a city wall but was entirely formed by vines.
More importantly, the entire vine city wall was in full bloom, filling the entire territory with a pleasant floral fragrance.
The entire Thorn City Wall encircled the territory, but its height was not very high, only five meters.
He then began to examine the attributes after the upgrade.
[Building: Thorn City Wall]

[Upgrade Required: 2,200,000 Spirit Coins, 600 Six-Star Wood-Attribute Crystal Cores]

[Description: A fence grown from thorny vines, with strong vitality, capable of self-repairing damaged fences, and possessing effects of poison, hallucination, confusion, and thorn attacks.]
After reviewing the attributes, he was astonished. Not only could the height of the Thorn City Wall be increased with spirit coins, but its exterior shape could also be freely altered.
"Let's try it."
Curiously, he began to change the entire Thorn City Wall.
First, he increased the height of the Thorn City Wall. Five meters was still too low.
Thorn City Wall Upgrade: "Do you wish to consume one million spirit coins to increase the height of the Thorn City Wall to six meters?"
Although one million was a significant amount, he wasn't concerned about the cost, as his current accumulated spirit coins were already in the tens of billions.
"Yes."
He increased the height of the Thorn City Wall to ten meters. The next increase would require two million. He didn't care about the spirit coin expenditure.
He raised the height of the Thorn City Wall to twenty meters. Subsequently, each meter of increase would cost three million spirit coins.
After thirty meters, each meter required four million spirit coins.
After forty meters, each meter required five million spirit coins.
After fifty meters, each meter required six million, allowing for a twenty-meter increase in height.
After eighty meters, each meter required seven million, allowing for a thirty-meter increase in height.
Finally, he raised the height of the Thorn City Wall to ninety meters, after which it could not be increased further without upgrading the building itself.
The Thorn City Wall served as the inner wall of the territory, while the outer wall was comprised of structures like the Great Wall.
With the expansion of the territory, the Great Wall had been upgraded to the Myriad Mile Great Wall.
He then began to change the exterior shape of the Thorn City Wall, using his mind to sculpt vine houses onto the wall, with the houses shaped like tiger heads.
From a distance, the Thorn City Wall now resembled a tiger-headed castle, which was quite peculiar.
Next, he changed the exterior of the entire Thorn City Wall, shaping it into the body of a colossal dragon, as if a green dragon covered in flowers was guarding the entire territory.
Furthermore, the dragon's head was oriented towards the main gate.
The dragon's head was depicted with its mouth open, forming an entrance for passage.
This design looked incredibly majestic and imposing, as well as highly ornamental.
In each direction of the territory, he sculpted gates. These were normally concealed and would only open when needed, functioning as automatic doors.
The appearance was both futuristic and novel.
He then sculpted castles of various animals on the Thorn City Wall, including a colossal elephant, a phoenix, a black tortoise, and a bull's head.
He was extremely satisfied with the Thorn City Wall. Although it had consumed a considerable amount of resources and spirit coins, the investment was well worth it.
Following this, he began to upgrade the territory's defense towers.
However, he could only upgrade the Blade Tower, Earthquake Tower, Meteor Tower, and Ice Tower. For other defense towers, materials were insufficient, requiring him to acquire more.
After upgrading these four types of defense towers to level fifty, the materials he had acquired were nearly depleted.
Materials of six-star and above were quite scarce.
He had no choice but to construct more defense towers to compensate for the lack of upgrade levels.
After the upgrade, the defense towers became more powerful and their defense capabilities were enhanced.
Once the defense towers were upgraded, he also raised the level of the Divine Weapon Workshop. However, due to a lack of materials, the Divine Weapon Workshop could only be upgraded to level 30.
Five-star stone was no longer sufficient, and even wood was running low.
He no longer had enough materials to upgrade the remaining buildings and could only focus on acquiring items first.
He checked the time; it was already past six o'clock.
He then entered the Myriad Realms Virtual Mall.
