Before the students began to move, Terry had already advanced the battle line outside the city wall.

And began to dispatch a large number of small lapels to avoid frontal battles and quickly conduct a thorough survey of the entire sand city.

It doesn't seem quite appropriate to say it's a "front".

Because the projection range includes an area outside the city wall.

But for some reason, those vampire bats would not fly out of the city wall.

This also means that as long as you don't formally set foot inside the city, there is almost no danger.

After the Special Division confirmed this, Vice President Kong ordered 23 classes to be mobilized, and more than 2,000 students began to move.

"This is the area we were assigned."

After Wang Daming led the students from Class 3 to the outside of the city wall, he pointed in front and said solemnly:

"See clearly, the boundary of the area is the city wall!

No one is allowed to enter the walls of the city,

Your practice time is still short,

The cultivation level is too low and the combat ability is insufficient.

Once you enter, your life will be in danger if you are targeted by those strange beasts!

Most of you are adults, and I hope you can take responsibility for your actions!"

After saying that, Wang Daming stopped looking at them, just walked to a large gap in the city wall, sat down cross-legged and began to practice.

The students also breathed a sigh of relief.

The "light heating furnace" has been taken away, but they still gather together as before.

Some students were slowly spreading futons on the ground while muttering: "Do you really think we are children? I won't make do with it. Besides, isn't there a city wall that separates us?"

Cheng Lin shook his head and smiled after hearing this.

The so-called "city wall" is really unreliable.

First, the city wall is very low, completely incomparable to the walls of large cities that are more than ten or even dozens of meters high.

Secondly, this city has been abandoned for a long time, and the city walls have long since collapsed, and are almost not intact. There are cracks and holes everywhere, and in some places, an entire city wall has collapsed, exposing large gaps.

According to the photos on the Internet, the side with the message engraved on it is the best preserved in the entire Shacheng.

Almost all the city walls in other directions are damaged to varying degrees and are filled with gaps. If someone wants to enter, it will not be easy.

Cheng Lin said nothing, pretending to be meditating on the surface, but in his heart he was looking for an opportunity to sneak in.

Unfortunately, there were too many eyes here, so he could only endure it for the time being.

Anyway, it stands to reason that this projection should exist for more than a day, but if it doesn't work, wait until dark at night before entering at night.

After making a plan, Cheng Lin felt at ease.

He turned over his hands and took out the supernatural power textbook.

He planned to take advantage of this time to learn the remaining superpowers.

The reason why he chose to learn this ability instead of improving the proficiency of "Flame Cut" was mainly because this ability should be very useful for him to enter the sand city.

"Macro Perception: Perception ability. After it is turned on, it will continue to consume spiritual energy to maintain the state of perception. It can predict attacks within 0.5 meters of the body."

Silently reading the introduction to this ability, Cheng Lin was quite moved.

According to this introduction, this ability is of great help in close combat.

Although the sensing range of 0.5 meters seems small, it has little effect.

But if he is fighting close to the enemy, the perception of this distance can help him avoid attacks more flexibly and accurately.

Flame Cut consumes a lot of money and the casting speed is also slow.

Although the consumption of golden dust is reduced, the usage scenarios are limited and the number of uses is also limited.

In Cheng Lin's view, for practitioners at the first-level realm, the effects of supernatural powers still cannot be fully reflected.

Relying on the spiritual energy stored in the body of a first-level cultivator, the descendants will basically be useless after releasing supernatural powers six or seven times in a row.

If it's an arena competition, six or seven superpowers are enough.

But this time when you enter Sand City, you will face tens of thousands of vampire bats.

If a fight breaks out, there may not be enough time to recover spiritual energy.

In this way, superpowers are sometimes not as useful as combat skills.

"This macro-perception field map is the simplest, but it has to be constructed within the body, which is very different from the elemental power... Moreover, in this case, it seems that the golden dust bonus cannot be used."

Cheng Lin thought about it and began to operate the practice method according to the requirements in the textbook.

And build a spiritual energy field at a special acupuncture point on the body.

Due to the limitation of body space, this aura field is very small, so although the structure is simple.

But the operation difficulty is several times more difficult than the other two.

Even with Cheng Lin's proficiency in the "Aura Drawing Technique", it took nearly five minutes to finally complete the construction.

The moment he finished, he felt the spiritual energy in his body begin to automatically input spiritual energy into that field.

And he suddenly had a very strange feeling.

It was as if... every pore in the body came alive, and an "eye" was born in each pore.

The path of the wind blowing past him suddenly became clear.

At this moment, a small insect flew past him.

When it came within 0.5 meters of Cheng Lin.

As if there were eyes on the back of his head, he raised his hand and flicked the insect away with his fingers.

"good!"

Cheng Lin's eyes lit up. The usefulness of this power exceeded his expectation.

It's not as tricky as "Cryogenic Fireball" and "Spiral Cutting" at all.

Even without the bonus, this can actually have a big effect.

"Based on this, the original version of this power can probably be sensed within 5 meters around you, right? As a result, the imitated castrated version only has 0.5 meters left... but the distance is shorter, and the accuracy seems to have improved."

Cheng Lin thought to himself.

After sensing it for a while, he silently calculated the cost of this power.

According to his rough induction, 0.05 accurate aura should be able to sustain macro perception for about 15 minutes.

This made him very satisfied.

And began to have an infinite fondness for the perception system.

"This perception-based superpower is too cost-effective..."

With the concentration of spiritual energy in the air in Sand City, Cheng Lin can replenish his spiritual energy very quickly.

In other words, as long as he is not caught in a continuous fierce battle, he can maintain the cost-free activation of "Macro Perception" through aura recovery.

This greatly improved his survivability.

Overjoyed, Cheng Lin was about to stop this power when his eyes suddenly moved.

Macro perception made him clearly aware that the wind blowing on him was increasing in a subtle but rapid manner!

"What's going on?"

Cheng Lin frowned, raised his head and looked around.

Then I found that the speed of the windmill in the distance in the city seemed to be speeding up again.

And those vampire bats flying in the mid-air of the city and fighting those sneaking little lapels suddenly broke away from the battle collectively.

Pulled up, gathered into one, facing the west, and began to make a squeaking sound.

Thousands of vampire bats gathered and instantly enveloped the city like a dark cloud.

The students nearby also saw this scene and were shocked.

"What's going on?"

"Wow, there are so many bats?"

"It should be Tris who started fighting with them, right?"

"I think so."

"It's just a furry. It doesn't look like they are going to fight at all. I feel like they are a little panicked. They are like animals before a storm, and they will behave abnormally."

Cheng Lin stared blankly at the vampire bats and suddenly thought of an incredible possibility.

He suddenly turned his head and looked to the west.
