Brad Karak City is a large city in the underworld. Here, there are tens of billions of undead, of course, most of them are the lowest-level undead.

And here, it is the largest city in this area. Inside it is a complete social system, with the concept of a country, kings, and even civil servants and generals. The structure is almost the same as the human world.

And the undead here, regardless of their low level, but each has wisdom, and the unwise undead are kept and enslaved as if they were livestock.

There is a god-level existence here to guard the city, but this god-level person lives here, because in the underworld, war is a common thing, but it will not affect the city of Brad. This city is the largest city within a few million square kilometers.

The scope of the territory is close to half a celestial dynasty, which is quite astonishing.

However, Chu Tian's goal was this city. He didn't know that there was a god-level existence here, but even if it was there, Chu Tian still had a way to escape.

Chu Tian now is no longer Chu Tian who has just entered the underworld.

Time, three months have passed in the cemetery.

In the past three months, Chu Tian first ate all the food and water stored in his ring, and then relied on the cheapest healing potions and barbecue in the summoning to survive.

Indeed, at the point of Chutian, one can survive without eating for a month, but everyone has a habit, and three meals a day are Chutian’s habit.

Fortunately, the crystal cores obtained every day are enough for Chu Tian to eat for hundreds of years. Chu Tian is not stingy with himself, but he always grills fish and barbecues when he eats. Soup or something.

However, the only four foods that changed the law made Chu Tian very helpless.

However, for Chu Tian, ​​he was helpless, and some food was very good after all. If others were thrown into this world, let alone eating, it would be good to survive.

Within three months, Chu Tian was like a locust. The undead left nothing in the land they passed, and they were all killed.

Perhaps, fair and objectively speaking, the undead is another form of life, but the undead will not reproduce and have no blood relationship. In addition, for death, any living beings are instinctive resistance and rejection. Chutian within three months, Instead of disgusting or indifferent to the killings, he was quite in favor of it.

Even Chu Tian also specially summoned a bunch of Velociraptor army. The Velociraptor army included various Velociraptors and Gorenosaurus, with a total number of more than 100 million, and they killed even more undead than the small shield crabs.

Because the main function of the small shield crab is not to fight, but to dig three feet of ground. In this world, you don't know how many undead are dead. Under the thick ground, there are crystal nuclei that have been accumulated over many years.

Chu Tian once tested that for every 100 meters of digging, Chu Tian can dig out nearly 10,000 crystal nuclei. Although each of them is a low-level crystal nucleus, when it is recycled, there is also a spiritual power that can be recovered.

In addition, one billion of the two billion small shield crabs are digging, and Chutian's daily harvest reaches more than tens of billions.

In three months, Chu Tian's mental power increased from two trillion to 67 trillion. It must be said that in the underworld, it is indeed Chutian's heaven.

But this time, Chu Tian was going to do a big deal. He wanted to attack the city and then kill all the undead in the city.

In such a huge city, Chu Tian can be sure that there must be countless undead in it, and there are many powerful undead, but this time Chu Tian was helpless.

Because Chu Tian wants to summon a new summoned beast, he must have sacrifices, and the so-called sacrifices are crystal nuclei, but they need the corresponding crystal nucleus, so Chu Tian is helpless.

Now, all the summoned beasts that Chutian can summon have reached the holy level, so the weakest one also needs a one-star holy crystal. If you say that there are water system, Chutian, there are also thunder system. When he acted with the wild lion war **** and others, he exchanged it for the dragon crystal.

However, Chu Tian wanted something more advanced, but he was helpless, but now there is a method that is most beneficial to Chu Tian in the system.

exchange.

Use two crystal nuclei of the same system to exchange for a crystal nucleus of a different system but the same level. In other words, if Chutian wants a three-star sacred crystal of the wind system, then two sacred crystals of the three-star undead system can be exchanged for One.

And the undead element is the most useless element for Chu Tian. Even if it is absorbed, it must be purified with Thunder Dou's holy power first to avoid any problems.

Therefore, in fact, such an exchange is the best for Chu Tian. Although the spiritual power is a little short of the time, but when it reaches the stage of the holy crystal, Chu Tian rarely recycles it, and it is used for absorption. .

As for the absorption, it takes too much effort. It takes the Lei Dou Holy Power to be purified before daring to absorb it, and the efficiency is too slow.

Therefore, it might as well be used for other crystal nuclei to summon more powerful summon orcs, and then kill the low-level undead, and use the undead crystal nucleus to recover it quickly.

It may be unfair to swap two for one, but for Chutian, it is absolutely practical.

And the reason why Chutian came to attack the city this time was really because of Chutian’s “economic” strain. There were no high-level crystal nuclei in his pocket, especially the crystal nucleus of the summoned beast that Chutian wanted to summon. Gone.

Therefore, Chu Tian wants to draw out powerful undead. Under Chu Tian’s thunder fighting sacred power and life fighting sacred power, the power of the undead belongs to the suppressed. Generally speaking, the five-star undead and the four-star Chutian It can be a tie, if Chu Tian used some small tricks or something, then it would definitely be Chu Tian's victory.

Of course, you can also use the unicorn to kill the enemy with a super field, and Chutian’s "World Destroying Thunder" fits this point, but the same as the original ultimate explosion, the number of times is limited. Poor, so the number of uses is very small, Chu Tian dare not act rashly.

And this time, Chu Tian is about to have a big one!

"Come out... Summoners!"

I saw that as soon as Chu Tian stretched out his hand, two billion small shield crabs and 100 million Velociraptors appeared all around the city in an instant. In an instant, countless undeads who were leading to the city screamed and roared. They got up, but more of them were swallowed by Chutian's summoned beasts in an instant.

Indeed, when facing the undead, the strength of Chu Tian's group of summoned beasts was not very good, but in a slight amount, it was enough to reincarnate one-star or even two-star undead.

And if you encounter a huge head, it will be even more tragedy, because the larger the head, the more Chutian's summoned beasts will attack them at the same time.

In this way, the higher the damage, the more tragic the result will be.

In an instant, countless summoned beasts began to attack wildly, and Chu Tian also took a deep breath, and began to take out a large number of flame crystal nuclei in the ring...

"Come out... Fire Dragon Army!"

This is Chutian's true trump card!
