The temporary base in Yan County has not encountered this incident for the time being, but there are quite a lot of zombies around, and even if there are many people hunting them, they still can't stop the growth of their numbers.

Since Lu Tian was going to stay for a while, he naturally had to pay attention to the safety of the base, if the base was surrounded by zombies, he would also be in danger.

Staring at the gradually growing snowflakes for a long time, Lu Tian sat cross-legged on the bed again, he felt that he was still a little bit close to breaking through, but this thin layer of bottlenecks could not be easily punctured.

This secret method of spiritual cultivation is a water grinding kung fu, just like forging steel, and it will not achieve any results without going through thousands of tempers.

The sea of spiritual mist in the sea of consciousness churned violently, and it was contracted by a small black hammer, as if there was a giant beast making noise, making Lu Tian's head hurt so much that it was about to explode, but his consciousness was extremely clear, which greatly enhanced the pain.

A few drops of cold sweat fell on the bed along the hair that had grown half an inch, and Lu Tian breathed a sigh of relief, loosened his frowning thick eyebrows, revealing a pair of deep and restrained eyes.

Unfortunately, it didn't work out.

Although he has not broken through the third layer for the time being, while Lu Tian is tempering his spiritual power, he is also desperately controlling his physical body, getting rid of the sequelae of losing his true yuan and most of his spiritual power, and his control of his physical body has improved a few points.

The external manifestation is that Lu Tian's aura has changed a lot, and the originally sharp aura cultivation has gradually converged, which has changed Lu Tian's temperament a lot.

So Lu Tian took a step further three days ago, and successfully unlocked the third layer of the ** seal, with the help of this moment, he experienced the mystery of ** again, and with more comprehension, he was able to control the pulse of his muscles and bones at this time, and slightly changed his body shape.

He can't do it to that extent, but if he wants to become taller and shorter, fatter and thinner, he can still complete it.

"I don't know if with my ability at this time, can I hide that guy?"

Lu Tian thought about it in his heart, but he still felt that it was not good, now it was possible to control the muscles and bones, but the smell of the human body and the deeper fluctuations were not something that could be covered up by ordinary means.

Removing this layer of shackles, Lu Tian's finely controlled ** strength has reached 500 kilograms, which he never expected.

"Xiao Qi, what's going on?"

"Master, it was you who tapped the potential of **, and naturally increased by a hundred kilograms out of thin air, and the total strength increased by a hundred kilograms."

"So, I still have a lot of untapped potential?"

"Of course, it is difficult for any creature to fully tap its own potential, such as human beings, in fact, only use 5% of their own potential, including intelligence and physical strength, theoretically speaking, even if human genes are not optimized by cultivation, they can exert 20 times their potential."

Lu Tian thought that these were all conclusions that had been made very early, but human beings are focused on the development of science and technology, and they do not pay so much attention to the development of their own potential, or the development is too difficult, even the top scientists have no good way.

"If a human being can exert his full potential, he can have 10 tons of strength, and the master has carried out genetic optimization twice, and the final potential is far greater than this number, but the power he has is less than half of the potential of ordinary people, if it weren't for the special exercises that the master cultivated before, it is estimated that there is not even half."

A look of surprise appeared on Lu Tian's face, and he asked with some curiosity, "Xiao Qi, how big is my ultimate potential?"

"Hehe, this number is a bit scary, let's not talk about intelligence for the time being, because this increase coefficient is not large. Let's just talk about ** power, Xiao Qi has analyzed the genes of human beings and found that this is a race with great potential, it can be said that as long as human beings continue to develop, there will be various excellent existences, and they are even expected to occupy a place in the cosmic civilization. ”

"And every time the human gene is optimized, theoretically speaking, the potential can be increased by about 2~12 times, and the master cultivates the most suitable exercises for himself, naturally every time he optimizes, the potential is developed to the extreme, and the master knows how big his potential is, right?"

Even Lu Tian's eyes showed a hint of fear, "144 times!" The power can reach more than 1440 tons, is this still human? ”

"Therefore, the master's genes or bloodline are extremely good, even if they have not reached the level of god-level bloodlines, they have reached the top grade of spirit-level bloodlines."

"Bloodline, this thing is also hierarchical?"

"Of course, let's talk about human beings on the earth, under normal circumstances, the offspring of people with excellent appearance are generally not ugly, and the offspring of humans with good physique will also have excellent physical fitness, which is a bit like a saying in your civilization: [Dragons give birth to dragons and phoenixes, and the sons of mice will make holes], the offspring of genetically excellent creatures have a greater probability of obtaining excellent genes, if the genes of a race become excellent, the entire race will become extremely powerful, and this is how some advanced races in the universe come from."

"And the grade of the bloodline or racial gene, the same as the level of the individual cold weapon, is also divided into three levels: mortal, spirit, and god, each level is three levels, a total of nine levels, the master's gene is barely considered to be the upper level of the spirit level, the general species after two genetic optimization, it is good to be able to obtain the lower bloodline of the spirit level, it can be seen that the master cultivates the perversion of the exercise, although this exercise is not the best, but it is the most suitable for the master, and it is tailored for the master by the old master with great magical powers."

Xiao Qi complimented its old master slightly, making Lu Tian have to sigh at his good luck.

"What level of race genes are the human beings on earth, or what level of bloodline?"

"The mortal level is above average, the potential is enough, but the development is very insufficient, and it is estimated that it is not as good as the primitive people."

"Well, okay, let's go back to the topic just now, I've only developed less than 4 thousandths now, which is too bad!"

"Don't worry, master, it is very difficult to develop physical potential, so that ordinary people have thousands of kilograms of strength, first of all, his ** can't bear it, so if you want to have huge strength, you must have a corresponding **, basically every time you take a step forward, the difficulty will increase by one point, this is the most difficult cultivation path, whether it is now, or other civilizations hundreds of millions of years ago, this is the most difficult of the many cultivation paths. So the master doesn't have to be presumptuous, you have done much better than your kindred. ”

"And master, your two genetic optimizations are assisted by external forces, do you remember the nameless fruit that the master ate when he got the inheritance, it not only provides energy to boost the master's cultivation, the most important thing is to improve the master's qualifications, and secretly optimize the master's genes, otherwise how could the master complete two genetic optimizations at this age, and it is the most perfect genetic optimization."

"Without these, what would happen if I practiced an ordinary exercise?"

Lu Tian was also a little curious, if he didn't have all this, what would have happened to him.

"Does the master really want to know?"

"Say, I'm not going to be hit."

"Hehe, the master may not have reached the prefecture level until now, and he can't even do the first genetic optimization."

Lu Tian smiled bitterly and touched his nose, sure enough, his qualifications are not outstanding, looking at this, at most, he is a medium talent, even if he enters the ancient martial arts realm, he may not be able to reach the innate in his life, let alone start genetic optimization.

He quickly adjusted his mentality, since he had encountered this inheritance, he should make good use of it and not let this opportunity down.

"Xiao Qi, that is, when I grope for my physical body, I will gradually tap my potential?"

"Well, of course, this process is relatively slow, and it is impossible to increase thousands of kilograms, but it can still improve a lot. The master's current potential is high, but the limit of what he can bear is only ten tons of strength, that is, the master can also double his strength, without worrying about cells, bones, muscle tissue, etc. ”

"How to raise the tolerance limit of **?"

"Simple, constantly strengthening, refining, developing, strengthening cells so that each cell becomes an engine; Open up the acupuncture points and make each acupuncture point become an energy pool; Temper the meridians, bones, and organs so that they are as tough as steel and can withstand more power. ”

"I feel like you're saying it simply, but if you want to strengthen and refine such a complex and fragile **, I don't have much confidence."

"What is the master anxious about, this is not something that can be done overnight, take the master's current ** strength, it has not been tempered for 15 years before he can have today's strength, and the master has reached the realm of returning to the yuan, and his lifespan has exceeded five hundred, and the time is very sufficient."

"Five hundred, I haven't used the True Yuan for a long time, I've almost forgotten my realm, I didn't expect that I can live for five hundred years now, it's unbelievable."

The congenital fetal breath can exceed the record of human lifespan, living past one hundred and fifty years old, but not more than 200 years old, and the Zhengang realm adds nearly one jiazi, which can reach 300 years old, and the Guiyuan realm adds more than 3 jiazi, which can live to five hundred years old, and the legendary Huayi realm can reach eight hundred years old, which is already a god-like existence, and with the strength of the vitality, this theoretical time will inevitably increase.

Of course, most of the ancient warriors can't live that long, and the world of the transcendent is not a nursing home, which can make people recuperate honestly, battles happen almost all the time, most of the ancient warriors are more or less with secret injuries, just like some people in the secular world who are sick and die early, 99% of these existences will not survive to the end of their lives, and they will burp in advance.

This also leads to the fact that the average life expectancy of ancient warriors can only be close to the lowest value of the theoretical lifespan, most of the congenital fetal breath is 150 years old, and the life span of the Zhengang Realm is about 200, as for the Guiyuan Realm, because it has almost disappeared in modern times, I just heard that it is more than 300 years old.

But even so, Lu Tian has not even finished a tenth of his life, he is really too young, and there is still a long life waiting for him.
