Wu Feng sent 3 professional thieves, all of them have the skill of swift wind walking, they are fast, and they are very hidden, so [Dead Spirit] should know that his thief hero has been discovered, and he may be on guard.

Only when the thieves pass over can they touch the side of his territory, and at the same time, Wu Feng is also thinking about how to prevent the thief hero from sneaking into his territory.

Now that his territory is indeed guarded by high-level defense towers, it is impossible to force a breakthrough, but rogue heroes or troops can infiltrate with stealth.

The "Lord's Knowledge Manual" records cases of infiltrating enemy territory with thieves and assassin classes to assassinate high-value targets, and a few more times will seriously slow down the enemy's development.

For example, the blue craftsman in Wu Feng's territory is a very good assassination target, and if he kills any blue craftsman, Wu Feng will suffer huge losses.

"It seems that you have to find a way to get a hidden building or defense tower, at least near the lord's heart, you need this kind of hidden facility."

Wu Feng wants to get the anti-concealment facility, the best way is of course to draw a lottery, and he still has a treasure chest key that has not been drawn.

Previously, his treasure chest keys had accumulated to 280 draws, and he now had more than 150 treasure chest keys in hand, so he could draw them twice in a hundred draws.

This is the key operation to get good things, Wu Feng has 30 green keys and 12 blue keys on hand, two hundred consecutive draws, and he will definitely be able to produce good things!

Wu Feng continued to extract, and the final income made his eyes spent, and in the process of extracting the white key, a lot of green items came out, and then with the addition of a soul shot, they became blue items.

The blue items at this stage are already very useful, like the blue challenge order produced in them, which can make Wu Feng always have a challenge.

There is also a magic tower summoning card, which is a kind of defense tower that can be hidden, which can protect the security of a large territory and can detect any abnormalities.

Wu Feng also immediately placed it under the steel city wall in the east, so that this defense tower could radiate to the largest possible territory.

Magic Watchtower: Excellent quality, attack power 40-80 points, can attack 1 time per second, covers an area of 30 meters * 30 meters, range 100 meters, defense 80 points, durability: 30,000 points.

Incidental Skills: True Vision, Magic Detection.

True Vision: Within 1000 meters of the magic watchtower, it will provide true vision, ignoring invisibility, camouflage and other abilities, and see the most realistic situation.

Magic Detection: The Magic Watchtower detects a 3x3 block area within 10 km, exposing it to the Lord's field of vision for 5 minutes with a 1-hour cooldown.

The true vision of the magic watchtower can be described as the nemesis of the thief profession, and the general stealth and camouflage cannot hide the magic watchtower.

Unless it is the kind of hero with strong hidden ability or strong shielding ability, it is possible to break through the real vision, but this kind of hero is at least an orange quality hero.

Wu Feng didn't have a perfect quality thief or assassin hero, let alone other lords.

"With the magic watchtower, and then the thief hero is coming, it's here to send people's heads! The artisans and civilians in the territory do not have to worry about being assassinated by thieves for the time being. ”

After Wu Feng built the magic tower, he felt a little safe, although the lethality of the magic tower itself was not strong, it was not enough than the green defense tower.

But the vision it provides, that's very important, like magic detection, which can detect an area from a distance, which is quite useful.

"Scarface said that there is a monster lair in this direction, so I will use magic detectives to test the effect......" Wu Feng thought of the information that Scarface had brought back before.

He hadn't had time to occupy the monster's lair, so Wu Feng activated magic detection, illuminating an area 4 kilometers from his territory.

Magic Detection forms an invisible magic eye above the area, suspended 300 meters in the air, and can be seen from a high vantage point.

This magic detection has its own real vision, so it can also be hidden, Wu Feng used this vision to see that there was a small monster lair of level 15 below, and there was actually a purple boss inside!

"Well, this ability is really good, it's quite useful, and when the challenge is over, you can go over there and see how it goes......"

Wu Feng recorded the situation in that area through his high-altitude vision, and he knew it all at once, which was much more efficient than an unprofessional hero.

This is the distance between the [Premature Spirit] and his territory is more than 10 kilometers, otherwise Wu Feng can get a glimpse of the situation in his territory with a magic detection.

This ability, combined with the heroes, can quickly find out the situation around the territory, and the effect is no worse than that of the purple tower.

"If there is a copy card, you can copy this magic watchtower, and build a little more magic watchtower when the territory expands, so that you can grasp the situation of the territory more clearly."

Wu Feng realized the valuable role of the magic watchtower, and he raised its priority to the highest level in the blue defense tower, and the Holy Light Tower could not compare with the magic watchtower.

In addition, there is also a building evolution card in the blue item, which is also the focus of Wu Feng's attention.

This item can be used to evolve buildings and improve their quality!

Building Evolution Card: Elite Quality, which allows the specified building to evolve and increase its quality by one level (up to Superior Quality).

Because the quality of this building evolution card is Excellent, its upper limit is to evolve green buildings into blue buildings.

Wu Feng immediately set his sights on several of his green buildings, the lord's hut, the goblin store, etc., all of which were green buildings.

"If you evolve into a Lord's hut, my living conditions can be upgraded, from an ordinary small house to a big house! It's a villa-like building......"

"So, I chose the Evolution Goblin Store......"
