"Ding, upgrading to the day after tomorrow requires 100 experience points, and the user has insufficient experience points and cannot be upgraded!"

Although the sound of the system was cold, it did smash into Lu Chen's heart like a meteorite, making him excited and unable to calm down for a long time.

"So, as long as I can get this so-called experience point, I can improve my cultivation?" Lu Chen's heart beat violently, "Not only that, it's not impossible to break through the innate and become a soul martial artist again!"

It took a long time for his mood to calm down, and Lu Chen continued to study the other functions of the auxiliary device.

When I opened the 'backpack', there were forty-eight small squares in it, but now only the first one was bright, and the rest were still gray.

And in the first position of the seventh row, there is a big plus sign, and Lu Chen guessed that if forty-eight small grids are not enough, this plus sign is used to expand.

"What's the use of a backpack, is it for stuffing, but how do you put things in it? Is it also mind manipulation?"

Lu Chen struggled to pull out the pillow under his head, gestured at the backpack, and suddenly with a light in his hand, the pillow disappeared and appeared in the first small compartment of the backpack, and there was a text introduction below: Inferior pillow!

"Sumeru mustard seeds, isn't this the prerogative of the Soul Warrior!" Lu Chen was completely shocked.

The martial soul is a symbol of the revenant, it is not only a bridge for the revenant to communicate with the heavens, but also can provide defense for the revenant. But it also has a function, that is, storage, according to different colors, different grades of martial spirits, the size of the space in it is also different.

There are three icons in the skill area, the first icon is a big black bull standing up, roaring in the sky, there is also an arrow symbol representing the upgrade in the lower right corner of the icon, and below the icon, there is a text explanation:

Mangniu Jue, a high-level mental method, can be cultivated up to the peak of innate ability, and the current level is 10 layers.

Looking at the upgrade button, Lu Chen couldn't help but click it, and the prompt sound of the system immediately sounded in his mind: "Upgrading to the Yellow Rank Low Level requires 10,000 experience points, 1,000 reputation points, and a realm soul warrior!

"My good man, this auxiliary device is really against the sky!" Lu Chen continued to admire and began to continue to check.

The second pattern is a willow tree fluttering in the wind, catkins, advanced light skills, the current level is 10 layers.

The third pattern is a tombstone, a big smasher, a high-level external attack, and the current level is 10 layers.

After looking at the skill area, Lu Chen opened the task area, but he didn't expect that there was a task inside, and below the task, there was a small shining golden star, indicating that the difficulty of this task was one star.

One-star main quest: Return to the Lu family and recapture the courtyard left by your father. Complete the task, reward 10,000 experience points, and 100 reputation points!

"Main quest? Could it be that there are other types of quests?" This auxiliary device has just arrived, and Lu Chen still can't figure out many of the functions in it, so he can only slowly explore.

Just when Lu Chen wanted to continue to study the pet area, a mosquito suddenly flew in his ear, buzzing, he waved his hand a few times, trying to drive this annoying mosquito away, but the mosquito was flying endlessly around his head, and there was a momentum of not biting Lu Chen and resolutely not leaving.

Syllable!

"Even you dare to bully me?" Lu Chen was angry, ignoring the pain, and when the mosquito stopped on his face, he slapped it into a pulp, but in the next moment, he was stunned again, and sighed again The metamorphosis of the auxiliary device.

"Kill a mosquito and gain 1 experience point!" the system's cold voice sounded.

"Killing mosquitoes can also gain experience points?" Lu Chen really didn't know how to express his surprise and excitement.

Lu Chen also lost interest in studying the pet area, and focused on his ears, only then did he feel that there were many mosquitoes in this room, and there was a buzzing sound everywhere.

He endured the severe pain, struggled to his feet, took off the clothes on his upper body, and began to deliberately attract mosquitoes. Sure enough, the mosquitoes couldn't stand the temptation and flew towards Lu Chen.

Bang Bang Bang!

Lu Chen was in pain and happy.

Because Lu Chen was injured, his efficiency in eliminating mosquitoes was not high, and when the white belly of the fish faintly came from the sky, he finally killed a hundred mosquitoes.

Lu Chen couldn't wait to turn on the auxiliary device, click on the character area, and saw that the button representing the upgrade had lit up, and there was a trace of excitement, a trace of hesitation, and a trace of fear in his heart.

He was afraid that it was all just a dream, "If it's really a dream, I hope never to wake up!"

Lu Chen took a deep breath, calmed down his mood, and firmly sent out the idea of upgrading at the upgrade button.

"Ding! upgrade to the day after tomorrow requires 100 experience points, whether to upgrade or not, please confirm!"

There was nothing to hesitate about, Lu Chen chose 'yes'!

At the moment when Lu Chen chose 'yes', a golden light suddenly flashed under the feet of the figure in the picture, hovering around it, and finally turned into a five-clawed golden dragon, roaring and plunging into the top of the figure's head.

And Lu Chen immediately felt the change in himself, and a trace of heat suddenly appeared in his dantian, which was a long-lost internal force, flowing back and forth around the dry sapling martial spirit.

Not only that, but all the external injuries on his body recovered at this moment, and his strength was also strengthened, and he had reached the standard of the first grade after tomorrow.

Lu Chen moved his right hand for a moment, and then punched out.

Woo!

The air was cracked open by fists, making a dull sound.

With all his strength, the fist strength reaches 100 catties, which is the first product of the day after tomorrow, and when it reaches 200 catties, it is the second grade of the day after tomorrow, and so on.

However, Lu Chen's situation is different from that of ordinary martial artists, ordinary martial artists, with all their strength, can use internal force to increase their own strength. And Lu Chen's meridians are now broken, and his dantian is damaged, and his strength to strike out a hundred catties is completely pure ** power.

Looking at his fist in surprise, Lu Chen's heart was beating rapidly, and a stream of blood rushed straight to his head, so that he felt a burst of blackness in front of him, and finally suppressed this excitement, a strong sleepiness surged into his heart, his eyelids instantly became as heavy as a thousand pounds, he closed his eyes, fell asleep on the bed and fell asleep.

Goo-goo-goo!

When he woke up, it was dusk, Lu Chen was awakened by hunger, he opened the door, and was going to find something to eat, but he almost collided with Su Yu, who was trying to come in.

Su Yu saw Lu Chen standing at the door, and said in surprise: "Young master, are you well?"

Lu Chen didn't answer Su Yu, he frowned, and said, "Xiaoyu, what's the matter with you?"

It turned out that Su Yu had a strong smell of sweat on her body, and some of her messy hair was stuck to her forehead with sweat, looking a little embarrassed.

Su Yu hurriedly took a few steps back, for fear that the smell of her sweat would stink Lu Chen, she lowered her head, tore the corners of her clothes with both hands, and said in a low voice: "In the morning, the owner sent someone to call the young master to mine, and I saw that the young master was sleeping soundly, so I ......."

"So you went in my place?" Lu Chen slapped his forehead violently, secretly scolding himself for being a bastard, he escalated his patronage to fight mosquitoes last night, and forgot about this matter. I didn't expect Su Yu to be so kind, she couldn't bear to wake up her sleeping self and went to mine alone.

A hundred catties of ore doesn't sound like much, it can even be said to be less, but this is black iron ore, which is famous for being hard and difficult to dig, that is, those mining slaves who have practiced martial arts, it is not easy to dig enough for a hundred catties of ore, not to mention Su Yu, who has not practiced martial arts and has a weak body.

Thinking of this, Lu Chen's heart softened, he stepped forward and grabbed Su Yu's hands, and said softly: "Xiaoyu, thank you!"

However, what he got was Su Yu's exclamation, and he pulled his hand back.

When Lu Chen took a look, he saw that Su Yu's white and tender hands were full of blisters, some of which had burst, and the wounds had turned white after the invasion of sweat.

Lu Chen's heart was sour, he grabbed Su Yu's wrist and pressed her to sit on the stone steps, "You sit first, I'll go get a basin of water to clean it for you." ”

Without waiting for Su Yu to speak, Lu Chen strode away.

Lu Chen brought a basin of hot water, grabbed Su Yu's little hand, wiped it gently, and cleaned off the dirt, but Lu Chen didn't find it, Su Yu was looking at him fixedly, with a strong affection in his eyes.

"Xiaoyu, the mining will be handed over to me in the future, and don't call me young master, we have depended on each other for so many years, I have already regarded you as a relative, you will call me brother in the future!"

Brother? Su Yu's face turned slightly pale, he didn't know what he thought, a trace of gloom flashed in his bright eyes, but he still nodded and shouted, "Brother!"

Because Lu Chen's physical injuries have all recovered after the upgrade, his efficiency in fighting mosquitoes at night is much faster, and after slaughtering mosquitoes for a night again, Lu Chen was successfully upgraded to the second grade of the day after tomorrow.

In the next few days, Lu Chen went to the mine to mine during the day, and at night he fought mosquitoes to upgrade, and he was really sleepy, so he lay down and rested for a while, but now the experience points required for upgrading are increasing, and Lu Chen's upgrade is getting slower and slower.

That night, after casually slapping a mosquito on his arm to death, Lu Chen turned on the auxiliary device upgrade screen, "I can finally upgrade to the fifth grade of the day after tomorrow!"

With a flash of golden light, Lu Chen's ** strength was further strengthened, but he couldn't use any internal force, without the blessing of internal force, no matter what level of martial arts, it was just some actions for him.

Looking at the experience points required to level up, it has reached 600 points, which means that Lu Chen has to kill 600 mosquitoes to advance to the next level.

Lu Chen only felt that his head was big for a while, he was idle, he closed his eyes and looked inward, there was still a hole in the center of the dantian, and the sapling martial soul floating in the sky was as usual, without the slightest movement, but Lu Chen's unintentional glance suddenly shook his whole body, and he was surprised: "What is that?"
