When all the external structures and circuits of the magic tower were arranged, the magic crystals soaked in the blood of the doppelganger puppets were also recuperated.

Then comes the most important step - carving the core of the magic.

It is necessary to crystallize the magic power, and use the technique like a miniature sculpture to carve a shape that matches the magic circuit, draws energy, and condenses the pool of magic power.

This is a very complex and delicate operation, and some of them have an extremely high failure rate, because they often go down with a knife, and if they are accidentally cut, a whole piece of magic crystals will be wasted.

But the core that has been warmed by blood alchemy is different, and its biggest benefit is that it gives the magic core a weak repair ability.

As long as you don't make mistakes consistently, make mistakes at a high frequency, and make too big mistakes, there is room for redemption.

Cautious and calm, Dugu Fu operated the magic crystals on the workbench with his mind, sometimes with a knife, sometimes with magic, sometimes with abilities...... The eyes are dazzlingly carved into the core of the magic.

Everyone else watched intently from the sidelines, engrossed.

It lasted for more than ten minutes.

On the surface of the processed magic core, a flash of spiritual light suddenly flashed, and the magic power began to circulate around the body, as if the original dead thing suddenly became a living thing.

Dugu wiped the sweat from his forehead and straightened his waist, a success!

Looking back at the circle of onlookers: "How are you doing?" ”

A circle of onlookers, the light on their bodies is flashing, and the wind is overflowing.

When he heard it, he laughed: "Can't you see this?" All upgraded. ”

Their original alchemy and blood alchemy levels were just past lv3.

After this busy day, coupled with the observation at this moment, before you know it, it is already lv4.

"Actually, it's about to be upgraded. Now LV4 is one-third. Guo Xingxing added.

The rest of the people nodded and proved: "If you observe it twice, you may be lucky enough to upgrade to lv5." This experience value is really rising, tsk...... What about yourself? ”

"It's also a third." Dugu smiled again, "After practicing these two again, there will be a ** promotion." ”

The craft of making a magic tower, even in the three-story world, is not a skill that anyone can master. Dugu Fu used it to upgrade to the level of the second-layer world, what else can he do if he doesn't experience it?

Everyone didn't speak anymore, Dugufu continued to process, and they continued to observe.

Not surprisingly, the remaining two magic cores were also successfully processed, Dugu Fu's body was shaken, the strong wind overflowed, and the alchemy and blood alchemy all reached lv7.

Reaching the limits of his supernatural abilities!

The three magic cores are finished!

It's just that apart from him, no one else has been upgraded to lv5. The smaller the level difference, the less experience will be gained from observation. And lv4 liters lv5 require experience points

It wasn't as easy as expected.

Next, just install a mana core on each tower, turn on the tower, make it run successfully, and initialize according to the client's requirements. They're done.

Because the construction is too fast, and there are too many people, among the zombies controlled, there are even more over-level bosses like the three-headed water snake.

In the past two days, although some siege monsters have gathered on the periphery one after another, it has been just a small fight, and it has not become a scale at all......

The real battle of urban attack and defense is still in the next few days.

And the commission signed by Dugu Fu and Hai Zishan only ends here, and everything else will be taken over by others, and they don't need their participation in the siege war.

First, if they participate, they will inevitably win meritorious deeds, and when the time comes, titles, treasures, loot, etc., it will not be easy to divide.

Second, they are worried about what they will do in the middle of the siege war, suddenly cause sabotage, and threaten something with the success or failure of the siege war.

Third, I'm worried that they've done it now. They had to arrange for their men to take over as soon as possible, inspecting the entire city inside and out, from top to bottom, in case there were any loopholes, before the real siege began.

Actually, it's the previous part that is really hard.

If it weren't for the shadow zombie army, there would have been many attritions along the way because of various accidents, ambushes, and attrition for various reasons.

When you get to the ground, clean up the site, and fight with the benthic devil fish and the three-headed water snake, the loss will be even greater!

It is also highly likely that it will not be able to be attacked at all.

Even if they take it with heavy losses, there are not many people left, the wounded, the disabled, and they can't transform the three-headed water snake and the benthic demon fish, they are bound to be ambushed by monsters from the dark region in all directions, and their troops will be overstretched.

And the troops of the ground army, which re-entered from the surface entrance, also faced the same crisis.

The first trip was able to enter smoothly because the monsters were unprepared, and once they were prepared, their march could not have been so smooth.

Illusion is used to lead people astray, control magic is used to kill people, and enchantment magic is used to make people panic...... There are many monsters in the dark region by such means.

The army of shadow zombies does not eat these congenitally, and the army of human players is different, even if it is guarded against all the time, it is impossible to be seamless.

When the time comes, the number of troops will continue to be reduced, and even if they arrive here, they will not be able to replenish their troops, and they will have to send troops from the ground, and they will often fall into an endless cycle.

Not to mention, during this time, they are also busy with the construction of towns and busy arranging defenses......

The topic is far away, in short, don't look at Dugu Fu with the zombie army all the way, as if he was playing in the mountains and rivers, and he did the thing.

It's not difficult for those who know, but it's not for those who are difficult, it's really the Shadow Fruit ability that is too suitable for doing this. It's not that simple to build a city underground.

Haizishan came up with materials, and spent a lot of money to ask Dugu Fu to help start, and he definitely didn't lose money.

However, although the core was completed, Dugu Fu didn't think about handing it over to the other party so soon.

Alchemy and blood alchemy lv7, plus the level 1 provided by Solomon's book, is lv8, and something can be done.

"Let's go, let's go back." Dugu Fu said to the proprietress .

The proprietress nodded, knowing what to do, and launched any door with her clone, leading everyone, and instantly teleported to a relatively remote teleportation point hundreds of kilometers away.

Leave everyone's doppelganger in the processing area to support the scene.

In the waypoint, there is only one player, pouting and not knowing what to do.

Everyone didn't care, the man continued to be busy, and the proprietress continued to chant incantations and cast any door.

When the white light of the teleportation flashed, the two sides passed by......

Suddenly, the player turned around: Hey, that ...... just now It seems to be a fifth-level magic arbitrary door?

Suddenly, Dugu Fu also looked in the direction where the player disappeared: Hey, that ...... just now It seems to be a manual correction of background data?

That guy is processing the magic core in the dark region, it shouldn't be him, right? The player shook his head and thought.

Follow behind his ass and track down the troublemaker, there is a ** person in ten who is the person, but Dugu Fu is sure.

However, there is no need to go back and confirm. Nothing can be done if it is confirmed.

Let the proprietress continue to transmit, one, two, three...... Within a few minutes, everyone was at the teleportation point in Shadow City.

I haven't seen it for two days, and the shadow city is still so lively, bustling, and the scope seems to have expanded.

The white light in the teleportation point came and went, and no one paid attention to the appearance of a few of them.

After entering his own city, Dugufu casually called up the city management interface, checked the city warehouse, and found that after two days, there was an additional income of 20 or 30 million.

Slide them onto the smart app's account and let them continue to slowly sell for cash.

A group of people did not delay, played a flying technique, and went straight to the magic tower.

"Huh? Can you use flying? Seeing their movements, many people were shocked.

Why? Because flying is forbidden in the Shadow City area, everyone walks on their feet. You can also do it if you have a flying technique, and the flight altitude cannot exceed three meters.

It's so chaotic that the sky is full of people flying around!

Suddenly, when they saw someone who could fly, many people thought that there was something wrong with the system in Shadow City.

There are some people who are greedy for savings, and their flying skills are higher.

"Brush!" With a flash of lightning, a ray of light shot down from the condensed magical darkness. Instantly crushed the man to the ground.

"Papapa...... several patrolling zombie guards rushed over, "If the flight altitude is too high, you will be fined and fined!" ”

"Damn, why?" The arrested person resisted angrily, why can't I fly if someone can fly?

But how can the zombie soldiers reason with him? If you ask for money and don't give it, then drag the prison as a backup battery. Dare to resist? If the crime is increased by one degree, the punishment will be increased by one day!

dragged away like a dead pig......

didn't know that there was such a small storm behind him. Dugu Fu and his party returned to the magic tower in Shadow City.

The magic tower is running as usual, and the shadow mages are busy, and everything is in order.

Enter the top floor of the tower, the top vault that is heavily guarded. The portal entrance to the Realm of Favor is still open here......

The door of the Realm of Favor can be opened once every 24 hours, not only for 24 hours at a time.

If you don't turn it off, it will always be on.

Walking to the white light of the portal, Dugu Fu took out the additional materials he had obtained from the six major forces, selected a few of them, and processed them in a dazzling manner.

This processing is not as delicate and complex as processing the magic core, that is its profundity, and it is not inferior to the magic core, after all, this is also a skill that can only be touched by alchemy lv8.

While operating, Dugu Fu explained: "The Domain of Favor, at first glance, seems to be located in another dimensional space. But it's not. ”

"The magic that can travel to another dimension and be precisely positioned is called the Otherworldly Gate, and it is a ninth-level magic."

"Or the seventh-level magic that can't be accurately located and has a huge error, the otherworldly teleportation, that's not what our current level can complete." rs
