For several days, some of the survivors in the shelter cleared the mountain of corpses outside the city wall, and some followed the patrol out to carry materials.
Stone, iron and other basic materials, including black stone ore, tungsten ore, moiré ore and other commonly used extraordinary minerals... are transported to the central warehouse of the shelter for storage in batches.
Tang Yu built a first-level, second-level, and third-level, three-tiered city wall around the abyss crack named "Resource Point No. 1", and arranged them separately according to the range of the defensive buildings.
The outermost third-level city wall is mainly composed of artillery. One-third of the artillery has been upgraded to the second level by Tang Yu. In addition, there is a level 1 mage tower every thirty meters. The defensive strength is far superior to that placed in the city wall. The walls outside the sanctuary.
On the second-level city wall, a third-level arrow tower was built every three meters. The total number of arrow towers exceeded two hundred... In order to completely defend this resource point, he also spent a lot of money.
On the first-level city wall closest to the abyss, Tang Yu built two new defensive buildings.
One is a square prism that is wider at the bottom and narrower at the top. It is more than fifteen meters high and is completely black. From time to time, flowing inscriptions flash on the prism.
Another type of defensive building is in the shape of a cylindrical tower with black and white stripes spaced apart, about eight or nine meters high. There are bifurcations at the top of the tower. What is eye-catching is that on the top bifurcation, there is a hexagonal shape suspended. The half-human crystal was slowly rotating, and the crystal mirror reflected dazzling light.
[Can suppress obelisks: Construct a domain force field covering a certain range, which can effectively suppress the enemy]
[Building requirements: Level 4 territory, 20,000 source crystals, 5,000 stone, 3,000 iron, 300 tungsten ore, 100 black stone]
When the territory was upgraded to level four, Tang Yu built an obelisk in the villa area and tried it himself. Walking into the area covered by the obelisk was equivalent to being affected by multiple negative effects such as weakness and slowness, at least. It can reduce his strength by half.
Even if it were replaced by powerful followers such as Elaine and Tai Lun, they would only be able to exert 70% to 80% of their combat power within the range.
The power that can crush the obelisk is worthy of its high price.
Tang Yu can also mark this suppressive force field as friend or foe to avoid indiscriminate suppression. However... being able to crush the obelisk has a fatal flaw, the range is not wide enough.
The coverage radius is two to three hundred meters, which is of little use to the long city wall defense line, unless he can build one every five hundred meters.
But if it is placed around the abyss crack of the 'No. 1 Resource Point', it will be just right.
In the past few days, Tang Yu ordered people to conduct detailed inspections of the cracks in the abyss and obtained data on the size of the cracks.
The length is 305.6 meters and the width is 89.8 meters, which is nearly twice the length of the crack on the east side.
Around the crack, on the first step at the front, Tang Yu built a total of three pressure obelisks, which were arranged overlapping back and forth. The suppression ranges of the obelisks overlapped, but the areas after superposition were suppressed. More capable.

[Super Magic Prism Tower: Sends a concentrated energy attack to the enemy in front]
[Building requirements: Level 5 territory, 8000 source crystal, 1000 stone, 1000 iron, 300 tungsten ore, 100 prism stone]
He had also built a prism tower to try out this newly unlocked defensive building in the fifth-level territory.
The results were far from satisfactory.
The Super Magic Prism Tower is a single-point attack. In terms of power, it is enough to rank first among all current defensive buildings. However, the Super Magic Prism Tower has many shortcomings. Its range is very narrow, and its range is only two hundred meters. It is not even comparable to the Arrow Tower. On... What left Tang Yu speechless the most was that the prism tower needed up to five seconds to store energy before sending out a concentrated energy beam to attack.
It's embarrassing that the range is still so short even though he's already fully charged... He can easily run out of the two-hundred-meter range in five seconds.
And even if it hits the enemy, the power of the Super Magic Prism Tower is at best higher than that of the floating tank's main gun at full power, and is far from being able to kill instantly or cause fatal damage to extraordinary demonized beasts. .
The Prism Tower had originally been abandoned by Tang Yu.
This time, because of the special terrain of the abyss crack, he thought of the Super Magic Prism Tower again.
Ten prism towers were arranged on the city wall closest to the crack. During an attempt to attack the demonized beast emerging from the crack, Tang Yu discovered that the super magic prism tower... was a little different.
The rotating hexagonal crystals on the top of the ten prism towers simultaneously emitted blue-purple light. It originally took five seconds to accumulate energy. In the blink of an eye, it was controlled by him and headed towards the most troublesome end of the group of demonized beasts. The Prism Tower that the demonized beast launched its attack from charged up its energy in an instant.
On the other nine auxiliary towers, the hexagonal crystals emit blue-purple beams of light, which are not directed towards the enemy, but connected with the hexagonal crystals on the main tower.
In this mode, the main tower attack requires almost no energy storage.
Tang Yu was confused.
As a system owner, a territorial lord, someone who can activate the God's perspective to control defensive buildings... He doesn't even know that there is such an operation mode? !
Can't you give me a manual for the system
Tang Yu named this mode 'connection mode' and made some attempts. In the connection mode, the energy storage time can be reduced by increasing the number of auxiliary towers, or the energy can be stored for five seconds to emit extremely powerful energy. A powerful beam attack... When the energy is fully charged, its short range can be improved to a certain extent.
Although there are no targets that can be used for actual measurement of the ten super magic prism towers connected, Tang Yu estimates that their power is enough to cause fatal damage to extraordinary demonized beasts.
Resource point No. 1 is stable!
…
Tang Yu has been very busy these days, very busy.
The layout of the defense line at Resource Point No. 1 cost him a lot of time and energy... Building so many defensive buildings would make him dizzy!
In addition, the construction of Green Lin Railway is also on the agenda.
Lindong's experts have planned a specific route and, escorted by a team of Ancestral Dragon warriors, have begun exploration along the way.
Green Shade is responsible for the defense of the railway line... In short, it is to build arrow towers along the railway line to defend against attacks by demonized beasts.
—There is no need to set up sub-territories. The construction of defensive buildings can be carried out in personal areas.
It's just more troublesome. The further away from the territory, the more materials other than source crystals are consumed. Fortunately, this time we cooperated with the Lindong military. The military had deep pockets and no shortage of manpower. Tang Yu proposed to let the other party collect wood. Stone and iron materials and transported to the requirements along the railway.
The construction method of using local materials can avoid a large consumption of basic materials... He can also take advantage of the trend to blackmail a wave of materials. Anyway, Lindong Army doesn't care about such things, um, for sure.
On the other hand, somewhat to Tang Yu's surprise, Gu Dong, a senior executive from Lindong, actually came to visit in person.
As a competitor and the one being abused, Gu Dong, who was visiting for the first time, seemed very peaceful with a warm smile on his face. After some discussion, both of them were very satisfied and walked out of the castle.
Gu Dong hopes to become an agent for Green Shade Rune equipment and sell the equipment to other large shelters to earn the price difference.
Tang Yu is also willing to have an additional equipment sales channel and share part of the profits, so that he can quickly expand the sales scope and build Luyin brand awareness.
It's a win-win!
After surviving the crisis of the demonic tide and showing the strength of the Green Shade Sanctuary, no one in Lincheng and even the surrounding areas was open to provocation. There were even fewer spies staying in the Sanctuary.
The territory ushered in a period of rapid development.
In the blink of an eye, two months passed.
