On the way back, Lin Feng couldn't wait and began to learn the upgraded best check-in system.

Open the panel.

In front of him, a virtual screen appeared that only the host could see.

In the center of the screen, there is a red "Learn" button.

Lin Feng hurry up and click to learn!

After a minute, the study is done.

【Ding!】

[Congratulations to the host, you have completed your studies!]

[A reward update package, is it open now?]

"Of course it's on!"

Lin Feng did not hesitate!

【Ding!】

【Successful opening!】

[Congratulations to the host, the Qi refining level has been upgraded to "Three-Rank Qi Master"!]

[Congratulations to the host for obtaining the "Qi Observation Technique" skill!]

[Congratulations to the host for obtaining a "Primary Invisibility Talisman"!]

[Congratulations to the host, the inventory slot has been expanded to 100!]

……

At last......

[Host: Lin Feng]

[Level: Three-Rank Qi Master]

[Skill: Fighting Technique, Qi Observation Technique]

[Talent: None]

[Backpack: Primary Invisibility Talisman, 1/100]

【Sign-in】

……

Lin Feng pressed his finger on the "Primary Invisibility Talisman" on the backpack bar, and then he saw its attributes.

【Primary Invisibility Talisman】

[Stealth duration: 3 minutes]

[Application: Stick to the skin]

With another tap, the invisibility charm was in his hand.

It turns out that the backpack bar is like a virtual storage room, where everything can be stored and easily accessed.

Lin Feng threw the primary invisibility talisman, as well as the Demon Suppression Bowl and the "Zhengying" brand peachwood sword obtained by signing in before, into the backpack bar, and then continued to study the new system.

Talent is empty and will be ignored for the time being.

Skills......

Fighting technique, Lin Feng had already experienced it once, and at that time, Ye Chen and his little brothers were crying wolf;

【Qi Observation Technique】

[Observe the aura of heaven and earth, the void and reality of yin and yang, the disease of the human body, and the profit and loss of luck!]

"Something!"

Lin Feng nodded, seemingly satisfied.

The property description page has a "Learn" button.

Lin Feng clicked "Learn" and immediately learned the Qi Observation Technique.

All of the above can only be regarded as icing on the cake.

What needs to be highlighted is the level - the third grade qi master!

The grade, naturally, is the level of qi refining.

There are seven realms for Qi refiners!

From low to high, they are Qi Master→ Qi Sect→ Qi Saint→ Qi King→ Qi Immortal→ Qi Divine → Qi Madness.

Among them, each realm is divided into nine levels, with one product being the lowest and nine being the highest.

Speaking of which, Lin Feng's third-grade qi master doesn't seem to be worth mentioning!

However, there is a contrast in everything.

The old man Zeng Qian, who was in the Nanjiang River, had cultivated for most of his life, and now he was only a second-grade qi master's cultivation.

As for Bai Zhantang, the heir of the Binjiang Flying Sword family, he only has the cultivation of a first-grade qi master.

Lin Feng, just completed the system task and killed the thousand-year-old snake demon, and directly killed the third-grade qi master!

If this spreads to the Qi Refining Realm, I'll have to be angry with those old guys!

……

After reading the level, skills, talents, and backpacks, Lin Feng finally pointed to the most important sign-in column.

The best sign-in system is, of course, the most important sign-in!

At this time, it was already past twelve o'clock in the morning.

A new day has arrived.

[Today's Registration: Unfinished]

【Sign-in location: GreenTree Inn Weiyang District, Room 1707】

[Check-in time: 1 hour]

【Check-in Reward: Summoning】

The system has been upgraded, and the check-in has also been upgraded, with the requirements of location and time.

Correspondingly, the rewards have also been upgraded to some extent.

Sign-in rewards, summoning skills, it's not easy to hear!

Now, there is only one check-in per day.

As for angering others, you can still get anger points, and these anger points can be directly converted into real anger!

In other words, don't look at Lin Feng's cultivation as only a third-grade qi master, but if he provokes others and gains a large amount of anger points, his true qi may even be higher than that of a fourth-grade qi master or a fifth-grade qi master!

It is not impossible to leapfrog the second person!

These are all learned by Lin Feng through the "Learn" button.

But, that's not the point!

The point is, today's sign-in location seems a bit bad!

GreenTree Inn Vejan District, Room 1707!

Isn't this exactly Pantene's room?

Nima!

Labor and management just came out of her!

Damn!

Now I have to go back and stay for another hour to complete the check-in?

I knew that I just pretended to be dead directly, and it would be over after lying there for an hour!

What is the reason to go back?

Lin Feng is big for a while!

However, no matter how difficult the sign-in is, it has to be completed with gritted teeth.

After all, the reward is summoning!

So, Lin Feng immediately turned around.

The boat will naturally go straight to the bridge, so let's go first!

……

GreenTree Inn Hotel, Room 1707.

Lin Feng stood at the door again, and his mood was a hundred times more nervous than before!

After thinking about it for a long time, I still couldn't think of any good excuses.

These lame excuses, let alone convince Pantene, even can't convince herself!

Since the bright one can't work, it seems that you can only play the yin one!

"That's right!"

"Isn't there a primary invisibility talisman in the backpack bar!"

"Or ...... Try it?"

Thinking of this, Lin Feng took out the talisman and stuck it on his skin.

With this post, something magical happened!

Lin Feng saw his figure and instantly became transparent.

I can still see a transparent shadow, but others, I can't see anything at all!

Because, even if Lin Feng ran to the waiter and grimaced, the other party didn't react at all!

Lin Feng was overjoyed and prepared to ring the doorbell.

As long as Pantene opens the door, he can get in.

Although the primary invisibility charm only has a three-minute time limit, this is enough for Lin Feng to find a place to hide, such as under the bed, in the bathroom, and behind the curtains......

Lin Feng was about to ring the doorbell when suddenly, there was a rush of footsteps in the corridor.

When I looked back, a doctor in a white coat, leading two nurses, was rushing towards this side with a stretcher.

The three of them couldn't see Lin Feng's existence at all, and when they arrived at the door of room 1707, they rang the doorbell violently.

"Who?"

Soon, there was a sound of footsteps inside, and then the door opened.

The doctor said, "Is that the emergency number you called?"

"Huh?"

Pantene was a little embarrassed and said, "I'm sorry, the patient has recovered!"

The doctor frowned and said, "Don't you need to check it out?"

Pantene said, "He's gone! Oh yes, I'll pay you for the bill, and I'll get my wallet!"

……

The moment Pantene opened the door, Lin Feng had already gotten in!

【Ding!】

[The host has arrived at the check-in location, and today's check-in has begun!]

【Time-Keeping ......】

Lin Feng circled around the guest room, but he couldn't find a suitable place to hide.

Under the bed, there is no space.

The bathroom, it's too conspicuous, in case Pantene goes to the toilet, there will be nothing to hide.

As for the curtains, they are a whole lot shorter, and if you hide in the back, the part below the knee will be exposed, as long as Pantene is not blind, she will definitely be able to see it!

Lin Feng was so anxious that he was dying!

It's almost three minutes, and the primary invisibility charm will expire soon!

What should I do?

Where to hide?
