Wang Yuyan and Serena changed their colors at the same time.

At this time, although adventurers from all over the country united and raced against time to prepare for the upcoming demon invasion. According to the intelligence collected by Maishella, adventurers on the borders of the West, the north and the south either received support from their own adventurers, or received a large amount of resources to build and reinforce the castle.

It should be said that adventurers from all over the world are not fools. In order to pass the test, many of their usual hatreds are put aside and they are fully prepared for the war. The defense on the border is relatively strong.

If the hell army attacks, although I dare not say that I can definitely defend the border, at least all countries are prepared to fight and can resist for a while.

But the Gonggen people's authentic battles are a trick to defeat the enemy.

Send a large army to explore the underground world while digging the above-ground passages!

According to their excavation speed, it is estimated that the underground passages with various countries will be opened in less than 2 weeks.

At present, adventurers from all over the world have not found an underground passage. It is estimated that only the central part of the territory of the Hell tribe can directly lead to Gonggen.

The authentic warfare of the Gonggens is extremely hidden, and the normal situation is that adventurers cannot detect it.

As long as they remain hidden and digging like this, they will surely appear suddenly in the rear where various countries think they are safe when adventurers are caught off guard!

Imagine it.

Two weeks later, one month after the Bloody City Gate was opened, the Gonggen people probably also had a black dragon!

Their arbitrary "dragonarmy" suddenly appeared in the rear of various countries!

Adventurers, if they cannot organize decent resistance, they will be attacked by the city one after another.

There will definitely be chaos in the world.

At this time, the demons in front took advantage of the adventurers' return to deal with the Dragon Army and then took advantage of the opportunity to attack from the front battlefield.

Fighting forward and back. Can adventurers survive?

It would be strange if you don’t die!

Du Yu took a deep breath.

The development of this situation has exceeded his estimate of the worst situation.

He felt strange.

How did the previous adventurers pass such difficulty?

In the church, Richelieu looked at the army of thousands of demons. Gradually, with a fire-yellow light, it suddenly appeared in the main city nearest to the Western Front!

He took a deep breath.

"I hope I can pass this time." Although many cardinals chose to leave after experiencing the blow of the magical artifact, Richelius did not leave.

Even if it is not for the secret of the artifact, at least, the 36 adventurers in the church will become the newest main force in the outer city. We must not abandon it.

Giving up lightly is not Richelieu's style.

"The difficulty this time is really very high." A cardinal comrade whispered: "I remember that I passed the Blood City Gate at that time, and I was invincible with heroes. Although it was difficult, it was not that difficult. The 400 main cities of hell are so powerful."

"Don't forget the Gongens who did not appear." Richelieu sneered: "They are not vegetarians. They may be engaged in any underground conspiracy."

"Why is it so difficult?"

"I think. The problem lies in the artifact." Richelieu stared at it for a while, and finally gritted his teeth and said something.

"Artifact?"

"We all know the power of the remaining space. They are all gathered at the Bloody City Gate, making it impossible for us to seep into it." Richelieu said.

"The artifact at the Blood-colored City Gate contains the most powerful rule power in space. For example, it announces the astrology results on behalf of the astrologer! Let the golden elves on the continent continue to appear on the ground. This is the power of rules!" Richelieu's words were astonishing.

"You mean, the Golden Elf Week that had lasted for two consecutive weeks. It was not accidental?" The Archbishops in the Cardinals were shocked.

Richelieu sneered: "I wasn't sure at first, but I had a strong premonition when I recalled the series of changes after the little thief got the artifact. The disaster of the golden elf must be related to the appearance of the artifact and the little thief."

"Since space cherishes the power of rules so much. According to the principle that the greater the reward for space, the higher the difficulty. To obtain this artifact and take it away, the difficulty is naturally higher than the ordinary blood-colored city gate." Richelieu sighed.

"The other three countries, no, the adventurers of the four countries have become cannon fodder for the little thief."

Catherine was also damning about it.

"It's so difficult, the most difficult Bloody City Gate I've ever seen."

Du Yu's eyes stared at the Gonggen army, and now they gradually dispersed. The bird-body witch was flying in all directions, screaming and using her sharp claws to test the hardness of the rock formation at the top of the cave. As expected, the cavemen began to use various tools to dig out weak rock formations and try to open up the passage with the ground.

"What should I do? Do you want it?" Serena stretched her hand.

Du Yu nodded: "Since we have discovered, these black hands will naturally be cut off. Come on!"

He took the lead and rushed into the caveman who was digging hard. The roar of the ghost prison wind made the caveman in hell fall to the ground and dizzy!

The caveman has no vision, mainly relying on ear strength and perception. He was attacked by Du Yu's internal force into sound waves by the internal force of the Yinfeng Roar of the Ghost Prison. In addition, the echo in the underground world is very heavy. For a moment, Du Yu's internal force roar echoed.

The addition of Li Mochou and Ning Zhong made the battle reach a white-hot level. After killing Liu Yixu, the two women shyly fulfilled their promise last night and stayed with Du Yu for absurd and warmed up all night. Today, they were full of energy. Meeting these fragile cavemen was simply the best tool for wanton massacre.

Serena held the Hunter Sword and slashed wildly. With each swing, she could cut off several cave people's heads!

But something strange happened.

Serena has expert undead skills: after the war, she will kill 3% of the number of enemies and become a vampire.

Her previous battle was relatively fierce and she killed very strongly, but the number of people was small.

This time, hundreds of weak cavemen became her excellent target of massacre.

As they were killing, the two dead Redskin Hell Cavemens stood up staggeringly.

Ning Zhongze was shocked and thought that this guy was not dead and was about to chop down, but was stopped by Du Yu.

"Wait a minute."

Du Yu smiled and looked at the Red Skin Hell Cavemen who were killed by Serena on both ends.

After shaking for a while, they gradually faded away the skin of the caveman. From their bodies, a creature with snow-white skin, body fluids, red eyes and sharp fangs was born!

vampire!

The fourth-level creature of the ghost clan!

Among the invincible heroes, the most shameless army.

The most terrifying thing about Vampires in Hero Invincible 3 is that they can suck blood and resurrect.

A vampire unit, as long as there are enough numbers, except for the ghost tribe who has no life and blood, it is unsolvable to face any race that can suck blood.

Even for advanced troops, as long as they can't kill the vampires at once and are counterattacked by the opponent, the vampires who died in battle will continue to be resurrected.

And Serena, killing these cavemen, can actually turn them into 3% of them into this terrifying creature!

This is the skeleton sea tactic in the hero invincible. Even the upgraded version of the Vampire Sea.

Usually, you need to get the vampire cloak, the undead talisman and the God of Death boots to synthesize a set of treasures called the Immortal King's Cloak. After wearing the ghost heroes, if they have expert undead skills, they can summon the lich.

But only Katherine has this skill that can produce vampires, and there is no other one.

Therefore, Du Yu ordered the beauties to stop attacking the cavemen and turn their attention to the bird-body banshee in the air.

Serena has only one mission - kill all the cavemen and try to create as many vampires as possible.

Although Du Yu had Elizabeth, facing the dual attacks of the demons on the ground and the Gonggens underground, he relied on the power of the magical artifacts to announce it as the week of the elves every week, and then recruited with Elizabeth's diplomatic skills, which is obviously not enough.

Another trump card is needed as a strong support.

That is the upgraded version of the Skeleton Sea tactics - Serena's Vampire Sea!

Use massive vampires to deal with the terrible Hell and the Gongen coalition.

Start now.

Serena didn't know that Du Yu had already put the heavy responsibility on her shoulders.

The moonlight goddess who had cut all the cavemen and killed them. She stood in her hands holding the hunter's long sword, and the surroundings were filled with blood.

Her long snow-white legs and sexy leather boots were covered with the blood of the cavemen. The blood was still answering with her evil hands and big sword, making her look particularly cold and evil.

But around her, there were more than 600 cavemen corpses lying.

Suddenly, a caveman's body moved

Then, the second head moved

A caveman slowly stood up and turned into a vampire, crawling under the little boots of Serena, the moonlight goddess

The dim light of the surrounding fluorescent minerals and plants shines on Serena's peerless face, with a cool look and standing quietly.

After massacring the cavemen, Serena had 18 vampires.

This is the terrible thing about the ghost clan.

Fighting to fight, and the more you fight, the more you fight, the more you fight.

In theory, as long as the ghost tribe is given enough time to develop and there are enough junior stints around, they are invincible.

It is this tactic that Du Yu wants to copy.

"But as far as I know, there are no cities around the ghost clan?" Wang Yuyan obviously thought of the classic tactic of Skeleton Sea.

In a city without ghost tribes, although Serena can summon a large number of vampires, she is unable to upgrade and her power cannot reach its peak.

"It's okay," Du Yu said calmly: "With Rogerhart, are you afraid that there will be no ghost city in this world? Even if there is not, there will always be a way to upgrade the temple or something."

As he said that, Serena had completed the cleaning of the caveman and the bird-body witch and returned to Du Yu: "What should I do next?"

Du Yu said: "There are probably not so few enemies. Serena, I'll give you a small army, so you sweep the invading cavemen and bird-body banshee around. I see that the enemy's posture is for reconnaissance + road construction. And it's only the third week, and the Gonggen people should not have advanced troops such as scorpion lions and black dragons. This week, you will be responsible for patrolling here and killing Gonggen who explores and builds the road." (To be continued...)
