Of course, this is just Lu Yu's feeling, his head didn't really blow up, if it really blew up, the book would be a eunuch.

As the roar fell, Lu Yu was dizzy and almost fell headlong, and he didn't know how long it took, but the scene in front of him slowly became clear.

Suddenly, Lu Yu reacted, it was the middle of the night, and there was no light in the house, how could he see it so clearly, it was the same as turning on the light, or even clearer.

Lu Yu suddenly stood up, walked to the window, looked into the distance, and was pleasantly surprised to find that his eyes seemed to have their own binoculars, and the scenery in the distance could be seen clearly, and it was also a telescope that could be automatically adjusted with consciousness, far and near at will.

Slowly, he found that it was not only his eyesight that changed, but also his hearing, and even as long as Lu Yu listened attentively, he could hear the noisy sound of playing games in the Internet café two thousand meters away, which was really too perverted, worthy of the spiritual power of the 8th level great master, against the sky.

Of course, the effect of mental power enhancement is not only these, memory, willpower, thinking ability, and so on have been strengthened, it can be said that Lu Yu, whose mental power has broken through a hundred points, can barely be regarded as superhuman, and the whole world seems to him to have pierced a membrane, becoming clearer and more real.

Lu Yu casually took out a nail from the carry-on space, controlled it with his mental power, and the sound of swishing breaking through the air flew all over the sky, and with a soft sound, it was as easy as penetrating a piece of paper to penetrate the bedroom door.

When the nail was retracted, it was found that the tip of the nail was slightly hot, which was caused by friction with the air when the speed was extremely fast. If he met Li Hu again at this time, Lu Yu believed that his nails would not only shoot into his head, but penetrate instantly, even if all his bones were strengthened.

The spiritual power of the great grandmaster level also has a perverted ability, that is, spiritual power detection, that is, it can detect the surrounding situation without using the naked eye, and it is unobstructed, even more real than what the eyes see, this is definitely a skill against the sky.

Lu Yu remembered the teacher's words, closed his eyes gently, and tried to use his mental power to perceive the surroundings, and the scene in the room instantly appeared in his mind. Lu Yu was overjoyed, and he was really good.

However, at this time, he did not reach the limit of his spiritual power, because he felt that he could continue to expand the range, and his spiritual power slowly extended, and he penetrated the wall effortlessly.

Slowly, the scenes within a radius of 100 meters appeared in Lu Yu's mind, although they couldn't be seen like their eyes, but they were more concrete, just like the old man two rooms away from him, Lu Yu clearly felt that he was staring at a book intently, his expression was excited, his eyes were straight, and his right hand was moving up and down quickly.

And Lu Yu could still feel that his heartbeat was accelerating. The rapid hormone secretion on the adrenal was obviously about to enter the sage time, and sure enough, within 10 seconds, the brother was agitated and cold.

This picture is too spicy to the eyes, Lu Yu hurriedly withdrew his spiritual power, and couldn't help but sigh, the effect of spiritual power is too wonderful, and the use is too great, with this skill, the grandmaster and below can be invincible.

Look at the remaining points, if you break through to the spiritual power of the 9th level Martial Saint level, it doesn't seem to be enough, and there is no recovery pill left, let's do this for the time being, go sell the diamond tomorrow, and then buy some strengthening pills and recovery pills.

Open the system layout:

Stamina: 340/342+

Spiritual Power: 0/0+

Spirit: 100/100+ (Spirit)

Credits: 5085

Carry-on space: 1 cubic meter

Skills: Black Iron Body (Dacheng) Extreme Speed Running (Dacheng) Mental Power Manipulation (Xiaocheng) Mental Piercing (Xiaocheng)

Although the spiritual power is very useful, but this point consumes more, and the current realm wants to make another breakthrough, the remaining points are definitely not enough, the spiritual power of the 8th level of the Great Grandmaster, the spiritual power of breaking through to the 9th level of the Martial Saint level is from 100 points to 1000 points, each point requires 8 points, which requires 7200 points, plus 10,000 points to break through the bottleneck, don't even think about it in a short time.

Looking at the exercises again, it takes 1000 points for the 'Black Iron Body' to be strengthened to perfection, 500 points for the extreme speed and cool running to be strengthened to perfection, 1000 points for mental power control to be strengthened to Dacheng, and 10000 points for perfection.

However, there is no promotion version of these two exercises in terms of spiritual power, that is to say, after strengthening to perfection, there is no room for improvement in the way skills are used, unless it is to continue to strengthen spiritual power, or to learn other ways, the use of spiritual power is not only these two.

Lu Yu looked at it, frowned and pondered for a while, and calculated the use of his points, the cultivation to strengthen to the 999 points of the peak of level 2 still needs about 1300 points, which is still 3700 points, and it takes 200 to break through the bottleneck and enter level 3, and there are 3500 left.

After level 3, it takes 3 points to add a little, which is 3000 points, and there are 500 left, and if you break through level 4, you need 300 points, which is the last 200, just enough for the next world to spare, and there are no extra points that can be used to strengthen skills.

So Lu Yu thought about it, or gave up the idea of strengthening skills, if you need to escape in a crisis, then strengthen the 'Extreme Cool Run', and don't strengthen it for the time being.

As long as you break through level 4, and then cooperate with your own mental power, ordinary people are really not their opponents, it is enough to cope with the college entrance examination, maybe you can also learn from others, go out and explore a danger or something.

Of course, Lu Yu will not go on an adventure unless it is absolutely necessary, there is a better way to make money, why can't he think about it so much.

However, sometimes there are unexpected circumstances, but will everything really go his way?

Speaking of money, Lu Yu looked at the diamonds and gold in his space, and he was happy and rich, hehehe. This night, Lu Yu was happy and didn't sleep well.

Early the next morning, I went to the Internet café to check the information to see where the diamonds could be sold, and after checking for a while, Lu Yu found that in fact, the diamonds or gold in this world are easy to sell.

It can be sold in jewelry stores, in warrior guilds, or in some weapon shops, because these materials are not only used to make jewelry, but can also be added in the process of crafting weapons and armor, which can strengthen the toughness and hardness of weapons.

However, as he slowly inquired, Lu Yu's heart became colder and colder, because he found that the gold and diamonds in this world were not as valuable as he imagined, and one gram of gold was only more than 30 yuan, which was ten times worse than what he estimated, but this was okay compared to diamonds.

The price of diamonds was even more different from what he estimated, and the angry Lu Yu almost vomited blood, because the price of diamonds was about the same as gold, and he searched unwillingly, and Lu Yu found the reason.

It seems that people in this world are more pragmatic and are not very interested in luxury goods and jewelry, and the things that are really valuable are items that can be used for cultivation and have energy, although diamonds are very beautiful, they are not among them.

Moreover, the world's diamond production is also very high, and basically every country has a lot of diamond mines. So a gram of diamonds is about the same price as a gram of gold. Yes, it's one gram, not one carat, the diamonds in this world are not calculated according to carats, and there is no division of color grade and cut grade, and the purity has a little impact, but it is not big.

When Lu Yu saw this price, his heart suddenly cooled a lot, the 190 kilograms of gold and 10 kilograms of diamonds he brought back were originally thought to be worth billions, but now it seems that it is good to be able to sell them for a few million.

The gap between this is too big, so Lu Yu can't accept it for a while, he wasted 200 points, and he got back millions, and he didn't know whether to lose or earn.

However, no matter what, it is useless to keep these things in his hands, Lu Yu still finds a place to sell them, and looks at the recommendations of netizens, it seems that selling them to the Martial Arts Guild is more suitable for him, and the price may be the first point than the jewelry store, but no matter how much he sells, he can eat it, and the confidentiality of the information is relatively high.
