"Silly girl, you don't have to be anyone's knife. Lei Qing gently stroked her hair with some pity, as if she loved her sister: "You just need to be yourself and have a clear conscience." Well, gossip Hugh. I see that you seem to have practiced some ordinary, non-caste Dou Qi Gong methods, and you obviously already have some foundation. Now, you carefully memorize all the Nether Dou Qi cultivation methods on this Assassin's Heart Sutra, and then I will guide you on how to use the Nether Crystal Nucleus to build a foundation and transform your Dou Qi surname into Netherworld. ”

Dou Qi is a complex and majestic science, Lei Qing has been cultivating for more than ten years, and he doesn't dare to say how deep he understands Dou Qi. But at least, he knew that to practice some Dou Qi Gong methods with a caste, he had to use the crystal nucleus of the corresponding caste to build a foundation. At the beginning, Lei Qing, with the help of his uncle, used a primary thunder surname crystal nucleus to complete the foundation of the Lei surname. After that, in the more than ten years of cultivation, more than a dozen thunder crystal nuclei have also been used, most of which are used when impacting bottlenecks and the like.

Of course, every demon beast crystal nucleus is worth a lot of money. Only some children of wealthy families are qualified to use crystal nuclei to cultivate, which is an extremely luxurious way. Even if it is a primary-level demon beast crystal nucleus, if it is sold, it will be enough for a common person to use it for a lifetime. Therefore, it is impossible for civilians or soldiers in the army to use crystal nuclei to cultivate.

Zuo Qianqian's memory is not bad, and her comprehension ability is also okay. It only took three days for Lei Qing to help Zuo Qianqian, who was eager to take revenge and eager to gain strength to avenge his grandfather, successfully build the foundation. transformed her faint ordinary fighting qi into a nether fighting qi.

Moreover, with the help of the remaining power of that primary Netherworld Crystal Nucleus, Zuo Qianqian's strength increased greatly after practicing the Assassin's Heart Sutra, and he successfully advanced to the Black Iron Beginner Rank. Theoretically, she is now a fighter. Although he is only at the beginning of the Black Iron Rank, if he enters the Emperor [***] team, he is already an elite warrior. After a few more years of seniority, you will be qualified to serve as some low-level officers at the level of squad leaders in the regular army.

For some civilians, if the talent for cultivating Dou Qi is good, entering the army is a very good way to get ahead. Of course, if you like to pursue exciting adventures, yearn for freedom, or have a greater need for money, it is not bad to join various mercenary groups. Although it is dangerous, it has a high degree of freedom, it is very exciting, and the money comes quickly. All kinds of dangers are also easy for people to break through.

Similarly, it is possible to join a miscellaneous organization or pledge allegiance to a family.

In short, generally speaking, if you can cultivate to the black iron level, you won't have to worry about having nothing to eat, and you will also have a small social status. Various harvests can feed an ordinary family and have a small surplus.

Of course, black iron is easy to repair, but bronze is difficult to practice. For those who have no resources, it is harder and harder, as long as the talent is okay. With all kinds of hard work, the black iron level can always be achieved. But many people, after cultivating all their lives, find it difficult to break through the black iron level and reach the bronze level.

Among them, there are three main constraints, resources, that is, various crystal nuclei and medicinal resources, and the second is that there is no excellent method of fighting qi. The third is talent and hard work.

Fortunately, Zuo Qianqian seems to have a good talent, and "The Heart Sutra of the Assassin" does not seem to be a big commodity, crystal nucleus, and there is no shortage for the time being. These are destined to Zuo Qianqian's future road, which should be much smoother than many people.

It's also thanks to her that she has this Assassin's Heart Sutra, otherwise, Lei Qing would not have been able to teach her to cultivate the "Three Changes of Heavenly Thunder" in her family. That is the cultivation method passed down from the family, and the foundation of the entire family's livelihood. Whoever dares to spread the word is basically no different from betraying the family, and the consequences are not just as simple as being spurned by the family.

Like Lei Qing's family tradition, in the "Assassin's Heart Sutra", there are also some combat techniques, and even, there are many scout experiences, assassination experiences, as well as various traps, reconnaissance, counter-reconnaissance and so on.

On the premise that Zuo Qianqian didn't mind at all, Lei Qing also read the Assassin's Heart Sutra to his heart's content, and he didn't care about those combat techniques. Just talking about those miscellaneous articles is enough to make Lei Qing gain a lot. These things are much more subtle than what they learned in the family.

Naturally, in order to truly own these things, we must continue to sharpen them through practice and imprint these methods and experiences into our bones. Otherwise, no matter how good the theoretical knowledge is, it is also an attic in the air and a moon in the water.

In three days, a broad and profound vindictive heart method was just a first glimpse of Zuo Qianqian. It's some simple combat techniques that she can use a little. For Netherworld Assassins, the most important thing is to stealth. Fighting skills also pursue the maximum power in a short period of time, striving for the effect of killing the enemy with one hit.

Frontal killing, or protracted combat with the enemy, was often not the way an Assassin should be. If you miss a blow, you can travel thousands of miles away. And, the orthodox Assassin, the Grim Reaper who walks in the shadows and darkness. The dark night when they can't see their fingers is their favorite.

And according to the description in the Assassin's Heart Sutra, if this sect Netherworld Fighting Qi is practiced to the highest depth, it will be cultivated to the highest level with the supporting body method "Shadow Step". Even under the fierce Qiankun, he can hide and hide, and kill people invisibly, which is very exaggerated.

Perhaps because she was taught by Zuo Lao since she was a child, Zuo Qianqian was already good at all kinds of stealth and concealment, and she was very familiar with this way, and her cultivation of shadow steps was extremely smooth. Lei Qing once experimented with it, in the dark, even if he was alert, this little girl could repeatedly perform shadow steps, and she was only discovered when she was about ten steps close to herself.

Although Zuo Qianqian was quite disappointed that she was discovered by Lei Qing every time, Lei Qing knew that this was already quite terrifying, not to mention that she was already a bronze high-level fighter, and her sense of acuity far exceeded that of ordinary people. Besides, after being chased and killed for several months, under the ambush, Lei Qing also has a lot of experience in anti-submarine tracking. At the least, Scott the Wolf is his best teacher so far.

After seven or eight days in a row, all of Lei Qing's injuries were recovered, his cultivation also increased slightly, and his realm stabilized at the bronze high level. The spirit is no longer outward, but introverted. At a glance, he looked much more mature and stable. With a calm and indifferent look, the prototype of a master can be faintly seen.

And Zuo Qianqian has also gained a lot. While working hard to cultivate the Netherworld Fighting Qi, he constantly sharpened "Shadow Step" and "Shadowless Thorn", the former is the body technique, and the latter is the fighting skill. The Shadowless Thorn is unleashed, silent, but explosive, picking on people to kill, and the Netherworld Fighting Qi will then be extremely treacherously attached to the body, entwining and destroying the opponent's meridians, preventing the enemy's Fighting Qi from running and playing.

In other words, even if a blow can't be fatal, it is not easy for the other party to get rid of the maggot-like encroachment of the Netherworld Fighting Qi.

Of course, Zuo Qianqian's cultivation time was extremely short, and he could only be regarded as barely mastering. It also takes countless exercises and time to sharpen and grow. Lei Qing personally realized that the best way to sharpen his fighting skills was in actual combat.

Between life and death, the potential of the human body is often stimulated and many things are comprehended.

For the first time since Lei Qing was hunted down, he had been idle for so many days, and his body was a little uncomfortable, as if he was about to rust. For sharpening and stabbing, it is natural to count the hateful and hateful thieves.

Assassins are often the best scouts. Scouts, on the other hand, are often good at assassination as well.

Lei Qingchu used to investigate, and it was obviously not good to deal with the masters, but taking advantage of the night, helping the new assassin Zuo Qianqian to reconnoiter some thieves and miscellaneous soldiers was not a big problem. And Zuo Qianqian has been cultivated since she was a child, and she has used these things to sharpen a lot of skills in hunting, and she is familiar with various investigation techniques, and she is still above Lei Qing.

Footprints, broken branches, smells, and various other remnants and traces. Those things are clearly revealed in the eyes of the scouts. It often reveals the number of enemies, their strength, their location, and even how long ago they passed by, or stayed here.

It took three days of hard work for the two to finally find their target and drop out of the group of thieves. At the same time, it also completes the reversal of roles between hunters and prey.
