Outside a human city, countless monsters emerged, some of which are similar to poisonous insects such as centipedes, spiders, scorpions, and other monsters, as well as lizard giant python dinosaurs, and of course, there are monsters such as demon dragon giant bats.

Of course, such a large-scale monster cannot hide it from human reconnaissance. In fact, those monsters do not intend to hide it from human reconnaissance. Obviously, they do not take a city of human reconnaissance seriously.

It was also because of the incident where Tongtian Spirit Treasure appeared in the city that people have been worried about being attacked, so they have comprehensively upgraded and transformed the defensive array early, and also stocked up a large number of spirit stones.

Unexpectedly, the attack still appeared. It was just that the attack was not the other races on the Fengyun Continent, but from the demon world. The moment they discovered the monster, the ultimate form of the defensive formation was immediately opened.

It imprisoned the airspace and earth within a radius of 100 miles, and at the same time it caused the turbulence of space, making it impossible for all strong people to tear the space and teleport it closer, and also allowed some monsters that could block their bodies to reveal their traces.

After allowing those monsters who can fly and escape to the ground within dozens of miles of the city, they completely lost their ability to fly and teleport, and could only get close to the ground.

...

All the monsters in their eyes were strange shapes, and they were so dark that they were rushing like a tide. However, the number of monsters was large and their strength was average, and they were obviously just a group of cannon fodder.

Many monsters did not even master any magical powers, but were mutated by energy radiation, and were only many times larger.

But no matter how powerful the body is, how strong the mutated shell is, and no matter how strong the defense is, it is just a physical body and will definitely not be able to stop the counterattack of the guardian formation of the human city.

After those formations that penetrate deep into the underground and connect to the earth and can directly leverage the power of all things in the world, there will be extremely sharp thorns on the ground, and the rain of meteors falling in the sky will harvest the nearby monsters in batches.

Standing on the city wall and cultivating, he also occasionally releases flying swords or ice cone lightning and other spells, strangling a few monsters that resisted the attack of the earth-stinging sky fire.

Occasionally, a very small number of monsters successfully broke through the defense line and successfully hit the guardian barrier outside the city wall. They were directly strangled by the defensive golden light of the guardian barrier, and they vaporized on the spot and didn't even have a trace of slag left.

"What's the point of controlling these demonized monsters to attack?" Xiaobai really couldn't figure out what the commander of the demon tribe wanted to do when he saw the monsters coming to die through the entrance mirror.

"These monsters are just to consume the energy of the guardian array." Bai's father next to him explained.

"The formation is not borrowed from the power of heaven and earth, so how can it be exhausted?"

"My son doesn't know that maintaining the operation of the defensive array requires a large amount of spirit stones to provide energy."

"...It seems that the formation is not good. The real innate formation can use the power of heaven, earth and all things to maintain its own operation."

"You are still young and don't know how powerful the demon clan is. These dead monsters carry evil aura from the demon world. After death, the evil aura on their bodies will be released, which can invade the innate formation. If there is no spirit stone to help maintain the formation, the guardian formation will be separated in an instant."

"Isn't anyone able to design a formation that converts the evil aura released from those monsters into spiritual energy?"

"How could there be such a formation in the world?"

"It's just energy conversion. How difficult it is? My fairy brother has designed a formation to convert evil energy into spiritual energy."

"Have you learned to reverse the magical formation of demonic energy into spiritual energy?"

"This, I prefer alchemy and haven't learned those complicated formations."

"What a pity. If there is still a chance next time, Jiuer must seize the opportunity to learn more of the upper realm divine formation."

"It's very difficult, I'm not good at it."

"No, my son is the first genius in the history of the human race. Otherwise, how could he be attracted by the Immortal Lord of the Upper Realm?"

"..." Looking at his father's proud expression, Xiaobai really didn't know how to explain. He really didn't have much talent, and Brother Bufan was not an immortal.

But then I thought about it, Brother Bufan could create the Tongtian Spirit Treasure at will. If this is not a big figure in the upper world, no one would believe it if he said it.

To create a spiritual treasure of the sky, you must master some of the laws of the great way, and master some of the laws of the great way. Even in the legendary fairy world, it is a very remarkable existence.

"Is Brother Bufan really a big shot in the fairy world, just sealing the memory so he doesn't know it himself?" Recalling Zhou Bufan's various magical features, Xiaobai suddenly felt that Zhou Bufan might be a venerable from the fairy world.

When I think of this, I suddenly feel an unprecedented sense of crisis. This sense of crisis is not the attack of the demons, but the fact that the gap between my identity and Zhou Bufan is too great.

I have been trying hard to catch up with Zhou Bufan's pace, but even if I try my best, I can't catch up. I had a little thought, my character exploded, and this time I proved that my strength in my dream increased greatly, so I could keep up with Brother Bufan's pace.

But now it seems that this is simply a delusion...

"Good daughter, what's wrong?" Seeing that the baby's daughter's mood suddenly became a little deeper, Bai's mother quickly asked.

"It's nothing, I just think my strength is growing too slowly now, so I'm going to refine the alchemy."

As he said that, he went back to the alchemy room directly, which made the two of them look at each other. They were just 14 years old and had already cultivated the Nascent Soul. But his strength is still growing too slowly?

...

Not to mention Xiaobai, who worked hard to refine alchemy to improve his strength, Zhou Bufan, who was moving around and heading towards the human world, encountered several monster attacks along the way.

Most of them are monsters that have been eroded by demonic energy. Of course, these monsters are not very threatening to Zhou Bufan, and they can even harvest some magic crystals after hunting.

However, I encountered monsters from time to time, and the spiritual energy in the world became much more violent. It was obvious that I had received the influence of the demonic energy, and the consequences would be unimaginable in the long run.

Especially when I worry that Xiaobai, who is far away in the human race, according to some information collected over the past few days, the human race in this world is really not very good. Almost every time the demons invade the human race, they are the first to be affected.

Of course, this is not the most critical. Xiaobai has the Heavenly Dao Bottle to protect himself, but the most critical thing is that Xiaobai was once a fox clan who practiced magic skills. If the soul is infected by the demonic energy and becomes demon again, the trouble will be great.

This situation really made Zhou Bufan a little anxious, but he couldn't get faster. Because of the large-scale invasion of the demons, a powerful guardian formation was opened everywhere.
