In the face of this kind of defense, the most effective is the formation, but after all, Yang Han's understanding of the formation is very rare, so it can't play a role.

[Trigger the current check-in, is it a check-in?]

At this moment, the voice in his head completely resolved his problem, and almost subconsciously Yang Han chose yes, and the sign-in reward was simply the best way to save the scene for himself.

[Sign in successfully, get the sign-in reward: Formation Grandmaster Attainment]

After receiving the sign-in reward, Yang Han only felt that his mind was filled with the knowledge of various formation mysteries.

The huge amount of information was constantly instilled in his mind, although there was a bit of a headache, but it was not unbearable, and as the information in his mind continued to increase, the phantom of the saint appeared behind him.

"It's a vision!" Bai Baihe exclaimed.

"Girl, this little boy is ......" Just as Zhou Tianheng was questioning, a huge roar suddenly came from outside the city.

"The beast tide is coming!" Zhou Tianheng's expression was on the side, and he quickly left the City Lord's Mansion at this moment.

And Bai Baihe also went out alone after glancing at Yang Han.

If you enter a state of epiphany, the time must be not short.

After they just left, Yang Han had already returned to normal, and when he saw the emptiness around him, his brows furrowed: "This is too immoral, just leave me for a while?"

At this moment, outside Chu City, it can already be seen that the birds in the distant woods have flown out of the jungle like frightened birds, and even the distant woods have been corroded, and the original verdant green has turned black, and then it is as terrifying as charcoal.

"The beast tide is coming!"

"The beast tide is coming!"

At this moment, the earth began to tremble, and groups of demon beasts came in the direction of Chu City.

"Fire attack!" At this moment, the boulder burning on the city wall suddenly began to be thrown, exploding in the group of demon beasts, and each explosion had at least twenty or thirty demon beasts die, and in the face of the death of their kind, they did not flinch, like a death squad towards Chu City.

A large number of flints, like meteorites, were thrown into the beast tide by catapults, like meteors, and at this moment, the entire periphery of Chu City had completely turned into a battlefield.

Under the consumption of flint, although the loss of the demon beast is a lot, but for the overall beast tide, the loss of the number is just a drop in the bucket, and there is still a steady stream of demon beasts in the rear, at the moment it is crazy, behind the demon beast, a black chicken more than three meters high slowly steps, every time it takes a step forward, the ground under its feet begins to fade.

It can be seen that its poison is strong, and he is completely like a monarch among demon beasts at the back.

"Aim at the rotten chicken for me! Hit me!" ordered the guard above Chu City at this moment.

At this moment, the archers were ready, and a column of alternate troops ignited the arrows and fired directly at the position of the rotten chicken, and tens of thousands of rockets continued to shoot at the position of the rotten chicken, but before they could get close to the rotten chicken, they had been completely corroded and disappeared.

Rao is blocking the demon beast has also arrived under the city, and the terrifying power of the demon beast directly collided with the city wall, and the entire city wall began to shake violently.

"Open the city gate, the iron horse will charge me, and you must definitely protect this city!"

At this moment, Bai Baihe was like a fairy, a sword was cut out, hundreds of meters long sword gang was cut out, and hundreds of demon beasts were cut in half.

"What a strength!"

"Such a strong kendo master, he is simply a heroine among women!"

"Oh my God, there is a savior in our Chu City!"

Bai Baihe's appearance instantly threw herself into battle, and her strength also gave the soldiers of the entire Chu City courage, at this moment, the city gate was wide open, and the iron horse rushed out and began to fight with the demon beast.

Hundreds of thousands of demon beasts, the number of demon beasts is more than the number of ordinary people in the entire Chu City, and the soldiers in Chu City are only one-tenth of the number of demon beasts, this should have been a battle without any suspense, as Bai Baihe began to kill in all directions, as if he had turned into a savior.

With the defeat of the demon beasts killed by the iron horse, in less than a stick of incense, the number of demon beasts that died in Bai Baihe's hands had already exceeded two thousand, but this number was still a drop in the bucket compared to the overall number of demon beasts.

And Yang Han had already appeared on the city wall of Chu City at this moment.

Yang Han also jumped off the city wall, and a solution had emerged in his mind at this moment, there were two forms of formations in the world of cultivating immortals, one was a formation based on some treasures containing rich spiritual energy, such as some heavenly and earthly treasures, which could often multiply and last for thousands of years, and then if it was used frequently, it would cause the formation to dry up or even disappear.

And there is another one, that is, the creation of heaven and earth uses the operation of heaven and earth aura to draw a formation, using the aura of heaven and earth as a driving force, and this kind of formation will not decay even if it is tens of millions of years.

It is the highest attainment in the formation, and the current Yang Han has already reached this kind of life, what he wants to construct is a trapping and killing integrated formation.

After Yang Han jumped down from the high platform, the number of demon beasts had been run-in by the iron horse Bai Baihe, and it was no longer fifty meters near Chu City, and even if there were, it was very rare, and it was more external, and he had already carved a formation pattern under his feet around the entire exterior first.

"Who is that little kid?"

"Hey, kids, it's dangerous, come up!"

"It's troublesome, how can such a young child and adult care about it, it's all man-eating monsters down here. ”

"I said are you stupid, this city wall is a fifteen-meter-high city wall, can a child jumping from the city wall be an ordinary person? I heard General Li Zhien say that suddenly there is a woman and a child to help resist the beast tide, and they are all strong people in the Dragon Transformation Secret Realm, I think they are them. A soldier reminded.

The news of the help of two dragon transformation secret realms was clearly conveyed among the soldiers of Chu City for the first time, and there are two people in the dragon transformation secret realm who have a high chance of being able to stop the rotten poisonous chicken, as long as the king of the demon beasts is blocked, the rest is not impossible to deal with, so the help of the two made the originally desperate Chu Cheng see a ray of light again.

At this moment, Bai Baihe killed into the group of demon beasts as if he was in a no-man's land, and no demon beast could get close to her, and soon her position gradually approached the rotten poisonous chicken, and after the rotten poisonous chicken, who had not made a move at this moment, saw Bai Baihe, there was murderous intent in his eyes, and soon black and lifeless smoke was emitted from the outside of his body.

These black smoke are completely poisonous to ordinary people, and they can turn people into poisonous water in a moment, Bai Baihe's eyes froze, and his palm held it
