Fantasy: I am in the desert, but the system lets me be the city lord

"By the way, there was no sandstorm just now, how could the sand elephant suddenly go crazy and run away?"

"Also, what are those tentacles?"

With curiosity, Zhou Lin lowered his head and began to look through the catalog in his hand.

"There is only one natural enemy of the sand elephant, the seabuckthorn beast! For a detailed introduction about the seabuckthorn beast, see page No. 15 of the catalog!"

Zhou Lin turned over.

"Sea buckthorn beast, a fourth-level monster, lives in the desert, but doesn't like high temperatures. It usually crawls under the sand, and its tentacles will emerge from the sand when eating. It likes to eat flesh and blood, and has a huge appetite."

"Sea buckthorn beasts have no eyes, and can obtain the specific location of their prey through vibrations on the sand or the smell of blood."

Wait, Tier [-]?
Nine Heavens Juezhen can only defend against Tier [-] monsters!

Zhou Lin shuddered, it's not going to go, it's not going to go!
Going out is home delivery.

Don't go out, wait until the seabuckthorn beast comes, it can dine in?

Just when he was at a loss, the voice of the system brought him hope!

"Ding... The system has detected a strong sense of crisis in the host, please make the following choices!"

"[-]. Repair the lord's mansion and obtain the marrow washing pill to enhance the physique!"

"Second, upgrade the Nine Heavens Juezhen, and get the temperature control function of the large formation!"

Zhou Lin was overjoyed.

The system is still reliable, knowing how to send charcoal in a timely manner!

but.

With the lessons learned from the past, he was not in a hurry to choose.

"Currently, I can only rely on the Nine Heavens Great Formation to defend, and repairing the lord's mansion is useless!"

"Also, after washing the marrow, the impurities in the body are removed, maybe the meat will be more fragrant to the seabuckthorn beast!"

"The current Nine Heavens Extinction Formation can defend against Tier [-] and below, but after upgrading, it can always defend Tier [-], right?"

Zhou Lin took it for granted, "I'll choose the second option!"

The voice fell.

A countdown panel also appeared in front of him.

3 minutes!
Zhou Lin continued to look at the catalog.

Before the formation was successfully upgraded, he didn't dare to move.

The seabuckthorn beast must be under the sand, as long as it moves, it will be discovered!
I didn't hunt myself before, maybe because I'm a waste?

Beads of sweat fell on Zhou Lin's forehead.

Fortunately, 3 minutes passed quickly.

"Nine Heavens Juezhen has been successfully upgraded! Congratulations to the host for obtaining the temperature control function!"

In my mind, a panel similar to the remote control of an air conditioner appeared.

And you can also specify different regions to regulate different temperatures.

"Hahaha, I'll hide from the sun first!"

He laughed out loud, took two steps in three steps, and ran to the shadow of the Lord's Mansion.

Before he could sit down, the sand at his feet suddenly shook!
It is exactly the same as the one that appeared next to the sand elephant corpse before!
What the fuck?

Just when he was in a daze.

Several tentacles jumped out from below!
Zhou Lin turned pale with fright, and subconsciously threw out the desert monster catalog in his hand!

"Whoa!"

The pages of the catalog were turned randomly, making a messy sound.

It immediately attracted the attention of the seabuckthorn beast.

The movement of the tentacles froze, and then retracted into the sand!
The moment the catalog landed, the tentacles came out again and sucked the catalog directly!

But after feeling that the catalog was not its food, the tentacles retracted again.

"The dog system cheated me! Isn't the Nine Heavens Extinct Formation upgraded? Why can the seabuckthorn beast come into the formation?"

Zhou Lin yelled at the system.

"Host, this system upgrade only increases the temperature control function, and does not enhance the defense!"

Hearing the system's answer, ten thousand muddy horses galloped past Zhou Lin's heart.

However, now is not the time to complain.

Think of a solution first.

"There is."

Zhou Lin's mind flashed!
The catalog just now seems to say that sea buckthorn beasts don't like high temperature?
