The underworld is good at making battle golems, and the underworld puppets are some underworld people who have committed serious crimes, or other shili or shijie, made of biological undead, or undead transformation. These people may have been good people in the past, but when they were made into puppets, their thinking ability was reduced, and they basically had no independent intelligence, so their security was very high.

The ghost introduced: "From the demon clan, the spirit clan, and the Xuan clan, there are high-level slaves for sale. Those slaves, although they have all the wisdom and ability, are much more troublesome to control, and the price is even more expensive. There are some slaves from unclean backgrounds, and there are very great dangers. These undead puppets created with the underworld jishu do not need to use any means, just extract a part of the soul fire, they will obey you, and there will never be the slightest disobedience and disobedience, this is the most haode guard! ”

Zhang Mu looked at the undead puppets.

If the funds allow, I hope to buy thirty or fifty Holy Spirits, so that I will not be afraid of ordinary rogue robbers. It's just that the price of the immortal puppet is much more expensive than the lower-level holy weapon, and it is definitely not something that Zhang Mu can afford at this stage.

Zhang Mu gave up buying the immortal puppet and walked into the largest room in the middle.

There are plenty of products of Nether death technology here.

The death technology of the underworld is different from the life technology of the insect world, and it is different from the magic technology of the spirit world and the cultivation technology of the Xuan world...... If life science and technology is to tap the potential of life, then death technology is with the help of the liliang of the dead soul, which is a science that has evolved completely on the basis of death, and its birth is related to the environment and background of the underworld.

In the case of the ships of the underworld.

The ship of the Underworld is a giant undead as a whole, and a man-made undead fire will be set up in the core area of the ship, which will be thrown into the undead fire with special soul fuel, thus releasing an astonishing amount of energy, enough to propel the ship forward and provide the energy needed for the weapon. Because of the artificial undead structure as the shell, the revenant fire as the core, and the soul as the fuel, the ships of the underworld are called necromantic ships, ghost ships, and ghost ships......

"This is the Soul Locking Tower!"

Zhang Mu walked in front of an ugly tower, which was more than 15 meters high, from top to bottom, full of holes, like a beehive, which exuded a cold atmosphere.

"Soul Locking can lock the souls of the dead, and if you catch a naturally formed ghost monster in the wild, or directly use the death ritual to turn your life into a ghost and throw it into this tower, they will be locked inside. At the first command, the souls of the dead have to come out and work for you, fight for you, and even plant and plow the fields. ”

Zhang Mu touched his chin: "It's really an amazing thing." ”

The ghost attendant continued, "Such a small soul locking tower can lock about 20,000 souls, and they are enough to help manage everything up and down the island. The Soul Locking Tower extracts energy from the Great Shijie environment and converts it into death energy to feed the souls of the dead at no additional cost. Therefore, the robot is much more cost-effective, tens of thousands of robots, the daily consumption is not small, and now buy the Soul Lock Tower, we will give away 5,000 ghosts! ”

Zhang Mu was very interested in the Soul Locking Tower, but he didn't plan to buy it. The Soul Locking Tower is not too expensive, and working with the soul of the dead is indeed much cheaper than a robot. However, most robots are intelligent and can store useful information, which is not comparable to the dull undead. Worm Island is full of ghosts, floating around, ghosts crying wolves, that scene is not very like, in the daily management of Worm Island, Zhang Mu does not plan to replace the robot for the time being.

"What is this?"

Lei Ming pointed to one of the towers and asked, this tower is also 15 meters high, the shape is different from the soul locking tower, the whole tower is like an iron pillar, but there are many hideous outlines on the iron pillar, all of them are the appearance of intelligent races, as if in the process of making the tower, it was directly sealed inside, and bursts of terrible and tragic screams came from the tower.

"This is called the Resentful Spirit Tower, which seals 2,000 Heavenly Spirit-level souls, and the Resentful Spirit Tower tortures the soul day and night, extracting energy from the pain and resentment generated by the soul, which is quite impressive. Don't look at a mere Wraith Tower, which produces enough energy to sustain a super-large barrier covering 20,000 square kilometers! It can also provide sufficient energy supply for the operation of the base. ”

Thunder frowned, staring at the twisted silhouette inside the tower, "This kind of thing isn't humane......"

The Wraith Tower is a very great invention in death technology, cheap and efficient, some developed underworld shili, using the Wraith Tower to transform into weapons, its horror is stronger than the magic guide weapon. If dozens of resentful spirit towers are built on Worm Island, the general rogue bandits will not be able to enter, let alone attack. The Resentful Spirit Tower itself is a kind of deterrent, in case of defeat and death, the soul is sealed in the Wraith Tower, it is the cruel torture of eternal eternity, and just thinking about it makes people shudder.

A small wraith tower is as high as 50,000 Realm Coins.

Zhang Mu couldn't afford it.

Secondly, the Resentful Spirit Tower pollutes the environment, and the negative spirit of the resentful spirit in the tower will affect the outside world, interfering with the lives of the people on Worm Island to a certain extent.

"This is a corpse grave......"

"This is the Tower of the Dead Soul......"

"This is the Abomination Synthesis Pool......"

"This is the corpse pool......

The Ghost Attendant is very patient, detailing everything from Death-Tech buildings to Death-Tech weapons. Zhang Mu didn't buy a single thing from beginning to end, purely as an opportunity to increase his knowledge, and after a detailed introduction by the ghost, he had a general understanding of death technology. This is a level 3 underworld civilization, the strength is really strong and terrifying, thinking of the base under Worm Island, maybe it also belongs to a level 3 civilization, Zhang Mu felt unsteady in his heart.

"There are a lot of good things here, we don't have to buy some back?"

Lei Ming felt that it was rare to visit, and it would be a pity if he didn't buy anything.

Zhang Mu thought about it and felt that it was too, pointing to a dilapidated and ghostly building and saying, "This necromantic temple, I want it!" ”

The ghost attendant said, "The Necronomicon Temple costs 12,000 Realm Coins!" ”

Zhang Mu emptied most of his pockets and bought a dilapidated house.

This is not an ordinary house, the shape is not important, the function is important.

The underworld, because of the abundant energy of death, has given birth to countless undead souls, and every small shijie, even extraterritorial shijie, is filled with a large number of necromantic monsters. In order to tame the wild undead, the underworld specializes in studying a mysterious ritual, the principle is too complicated, in fact, to put it bluntly, it is to forcibly plant the idea of the city government into the soul of the undead in a way, so as to achieve the purpose of taming.

The function of the Necronomicon Temple is to domesticate the land of the undead.

The violent and ferocious spirits entered it and soon became docile and obedient, hence the name "temple", as if to influence them. In essence, this is a special altar, or place of ceremony.

In fact, powerful undead are very difficult to catch.

Especially outside the underworld, the number of undead is scarce, and the races outside the underworld do not have the right method and suitable tools to catch the undead, so the death temple is the most unpopular among all kinds of death products.

Zhang Mu's money was not enough to spend, so he naturally bought it after some careful consideration.

The coffin of the Immortal can turn the corpse of the strong into the undead!

Therefore, the source of the undead is not a problem.

The undead that the Hades coffin can control are limited after all, if the undead liliang is too strong, or the number of undead is too strong, then there will be a situation of getting out of control. But what if the coffin of Hades was placed in the Temple of Death? The Hades coffin only needs to be manufactured, and it no longer needs to be controlled, and after the undead are created, they will immediately use the liliang of the necromancer temple to domesticate it, so that the complementarity is insufficient, isn't it the best of both worlds?

"There are too many good things, but it's a pity that there is no money."

"Let's go."

Zhang Mu didn't look at the goods inside the door on the right, and left the store with a sigh. The merchants of the underworld sent the Temple of Death to the airport, and the people of the Aoki Demon Clan will temporarily take care of it for the third time, and Zhang Mu will take it away when he leaves the Crystal Island.

The Crystal Island is more than 100,000 square kilometers, and thousands of shili carry out commercial activities on the island.

Zhang Mucai walked around for a while, and most of his waist bag was empty.

He went to some demon clan stores again, spirit beasts, rare beast cubs, basically from the demon world, and even adult holy beasts can be bought, but the price is extremely expensive, and Zhang Mu can definitely afford it. Zhang Mu bought knowledge, materials, and intelligence in the hands of some small traders, and calculated the time, and there was still more than one hour.

"We don't have enough money, there's nothing to see, let's go back."

Zhang Mu planned to rendezvous with the Great Sage of Heavenly Rebellion.

Suddenly, thunder screamed, "That shop...... How strange! ”

It was a shop made of dark crystal, it was bigger than the level 3 underworld shop I had been to before, such a big shop, it was supposed to be a crowd, but from the open door, there was no one inside and out!

Lei Ming glanced at the sign at the door and said, "Netherworld, this is Netherworld!" ”

"Cyborg?" Zhang Mu showed a puzzled look, "After walking down so many streets, I have never seen anyone from the mechanical clan. ”

Among the Six Realms, the Netherworld is the most unique.

This is a very orderly territory, the entire Netherworld is occupied by mechanical beings with independent will, there is very little information about the Netherworld, and the mecha because of innate limitations, it seems that there is no existence comparable to the Aoki Demon God. The mechanical technology of the Netherworld is very terrifying, and the precision, accuracy, and powerful computing power allow the mechanical clan to lock onto an island that is hundreds of millions of miles away and destroy it with one blow.

This kind of opponent, I'm afraid the Void Emperor doesn't want to provoke either.

The store was empty, there were no customers, no shopkeepers, and there was a strange feeling.

Zhang Mu looked around, and the decoration style in the house made him suddenly feel familiar. He walked over to the counter and found a magic circle on the ground.

"No......"

Zhang Mu's pupils shrank slightly.

Groping it up from the body.

"I'm glad I had this thing with ......"

Zhang Mu opened his palm, and a worn-out pocket watch fell.
