"I'm going to use the red line!"

With three points of nervousness and seven points of excitement, Lin Feng silently recited this sentence aloud in his heart, and soon, the cute laughter also reached his ears.

"Hee-hee, do you use props—red thread?"

"Yes!"

"Then please choose the target where the red line is used?"

"The goal is exquisite!"

"Okay, master, please wait!"

"Huh!"

I saw that the red thread in his hand suddenly wrapped around Lin Feng's wrist, and the other end of the red thread passed through the wall of this cell and was connected to the wrist of Linglong who was sleeping in the next cell!

Immediately after, the red thread flashed several times in a row, and then slowly disappeared, and at the same time, a cute giggle came from Lin Feng's ears.

"Hee-hee, master, the red line has been used successfully!"

Lin Feng couldn't help but blink, and then asked cautiously, "Mengmeng, are you sure that this red line has been used successfully?"

"Master, I'm very sure that this red thread has been used successfully, is Meng Meng still going to lie to you?" Meng Meng seemed a little angry.

"Oh, okay, thank you for your hard work, Meng Meng, you are awesome!" Lin Feng hurriedly praised Meng Meng a few words.

"Hee-hee! Thank you for the compliment, is there anything else the master wants to tell Mengmeng to do?" Mengmeng immediately became happy.

"Hehe, there's nothing else to do for the time being, Mengmeng, it's not early, you better go to bed early, right?"

"Okay, master, good night!"

"Good night!"

......

Lin Feng seems to have forgotten that Meng Meng is just an intelligent system, and the intelligent system does not need to sleep, but Meng Meng enjoys this feeling very much, and enjoys the feeling of being treated by Lin Feng as a human being, as a friend, and as a companion.

Perhaps, this is the reason why Meng Meng has always behaved very well-behaved in front of Lin Feng!

......

The next day, Lin Feng went deep into the mine to dig lava concentrate, and at 5:30 p.m., he came to the mouth of the mine on time to wait for Linglong.

Linglong, as usual, appeared at the entrance of the mine at 5:50 p.m. on time.

Lin Feng handed over the 20 lava concentrates he dug up today to Linglong, and after Linglong thanked him politely, he actually said to Lin Feng with concern: "Your injuries have not fully recovered, don't force yourself too much." ”

I rub!

Is the red line starting to work?

Is this the rhythm of Linglong's wife slowly throwing herself into her husband's arms?

I'm looking forward to it!

......

So, in the following days, Lin Feng would go deep into the mine every day to dig lava concentrate, and then every day at 5:30 p.m., waiting for Linglong at the entrance of the mine on time.

Day in and day out, rain or shine!

With the passage of time, Linglong's attitude towards Lin Feng has softened, she is no longer so cold, and even sometimes she will talk and laugh with Lin Feng, and the relationship between the two can be regarded as slowly becoming familiar.

And during this period of time, Lin Feng's internal injuries have also recovered a few points, but overall, the situation is still not optimistic!

The injury has not healed, and his strength has plummeted, how can Lin Feng escape safely from this ghost place?

Thankfully, Bei Mingjing seemed to have forgotten about Lin Feng's existence, and after she threw Lin Feng here, she ignored her and disappeared for two months.

Forget it!

At least Lin Feng didn't have to be sent to the laboratory for slicing research, and at the same time, it also gave Lin Feng a chance to breathe, as long as he stayed here with peace of mind and slowly recuperated from his injuries, one day, Lin Feng would recover and escape from this ghost place!

When Lin Feng escapes, that is, when the end of the North Underworld comes, Lin Feng will repay all the humiliations he has suffered during this period to the North Underworld a hundredfold and a thousandfold!

A gentleman takes revenge, ten years is not too late!

Now Lin Feng can only comfort himself with this sentence!

......

When a new day came, Lin Feng, as usual, carried a small basket on his back, carried a miner's hoe, hummed a little tune, and jumped to the deepest part of the mine.

After a month of excavation, the inside of this hidden mine road has been dug out by Lin Feng!

However, since the fork is only a few meters long and can only accommodate one person, it is more appropriate to call it a fork than a cave.

I saw Lin Feng walk to the mouth of the cave, then put down his back basket, and then got into the cave, and began a boring and boring mining career.

"Ding, Ding, Ding......"

The sound of the hoe smashing against the stone wall was crisp and melodious, echoing in the quiet tunnel.

The same scene is happening in all corners of the mine, almost every slave is working hard, and no one dares to be lazy.

One Lava Concentrate, two Lava Concentrates, three Lava Concentrates......

As time passed, Lin Feng dug up hundreds of lava concentrates, and this was also his biggest harvest!

"Whoa!"

Just when Lin Feng was about to drink saliva and rest for a while, the mine hoe in his hand suddenly sank, and then, the stone wall in front of him was directly chiseled!

What's the situation?

Lin Feng was slightly stunned at first, and then quickly leaned down next to the gap that had been chiseled.

Although this gap was only the size of a fist, it did not prevent Lin Feng from looking through the gap to observe the situation inside.

Black!

It's so dark inside!

However, Lin Feng could be sure that behind this stone wall, there was a hidden underground space!

This discovery immediately made Lin Feng excited, especially when he thought of the underground secret room that Linglong had discovered, Lin Feng became even more excited!

Don't say anything, just chisel through this stone wall, and then see what treasure is inside?

So, Lin Feng swung his hoe again, desperately digging at the gap.

"Ding, Ding, Ding......"

"Whoa!"

Half an hour later, the gap that was originally the size of a fist was finally chiseled into the size of a basin by Lin Feng.

I saw Lin Feng put away the mine hoe and rested in place for a while, and then followed the gap and carefully climbed in.

Because the light inside was too dim, Lin Feng couldn't see the surrounding situation clearly at all, so when he had just climbed in and hadn't even gained a firm footing, his feet suddenly emptied, and then, the whole person fell!

"Bang!"

"Poof!"

"Boom!"

"Bang dang!"

Stumbling all the way, Lin Feng didn't know how many times he was hit, and after about 10 seconds, he finally fell on a flat ground.

"It hurts!"

I saw Lin Feng reach out and cover his head, especially the two big bags on his forehead, and then kept inhaling, looking quite embarrassed.

The head of a fourth-level evolutionary can also be knocked out of the bag?

This only proves that the rock in the mine is very hard, and even the head of a fourth-level evolutionary can't resist a collision!

Rubbing the two big bags slightly, Lin Feng hurriedly got up from the ground, and at this time, a faint light suddenly came into his eyes from not far ahead.

Hey?

What's glowing?

Driven by curiosity, Lin Feng raised his feet and walked in the direction of that glimmer of light.

Soon, a small hole appeared in front of Lin Feng's eyes, and the glimmer of light he saw just now shone out of the cave!

"Click, click, click......"

Lin Feng cautiously touched the side of the cave entrance, and then cautiously poked his head out and looked inside.

When the scene inside the cave appeared in Lin Feng's sight, this guy couldn't help but widen his eyes, open his mouth wide, and even his breathing became short!

I rub!

Treasure has been discovered!

Dude's luck is finally back!
