Although there is indeed a weakness, it is not easy to attack Qi An's weak point, Li Changsheng can only try his best, it is difficult to say whether he can attack, and whether he can cause damage remains to be verified.

Qi An was stabbed in the back, but he didn't break the defense, he was both surprised and happy, and continued to think about ways to deal with Li Changsheng. In the face of the unpredictable [Ghost Knife], while trying his best to resist, Qi An paid more attention to observing Li Changsheng to see if there were any flaws to be found.

Although the two fought non-stop, they were more inclined to observe their opponents and look for weaknesses, especially Li Changsheng, since he knew that most of the attacks were ineffective against Qi An, the offensive converged a lot, and the suppression of Qi An was relaxed a lot. By doing so, he just gave Qi An enough time to breathe and make Qi An better observe him.

Li Changsheng's [Ghost Knife] was very subtle, more difficult to deal with than any kind of martial arts that Qi An had encountered before, even Mao Buping, who was stronger than Li Changsheng, was inferior to Li Changsheng in terms of martial arts skills.

Through Li Changsheng's careful observation and his own personal recruitment, Qi An was gradually touched.

Qi An has a characteristic, his comprehension ability and learning ability are very strong, and he often observes the opponent in battle, learns from the opponent, in order to find his own shortcomings, and at the same time improves, so he often gets stronger and stronger, and even breaks through and improves in battle.

It's the same this time, the smart and careful Qi Xin slowly discovered that the real power of the [Ghost Knife] is not the knife, but the unpredictable body like a ghost, the body and the knife are closely combined, no matter the attack, Defend or dodge, both use the body method to drive the knife method, and at the same time, in turn with the help of the knife method to drive the body method, the two promote each other, complement each other, the body to the knife, the knife is the body, the body is the knife, the knife is also the body, the body and the knife are truly perfectly integrated into one, without distinguishing each other, this is probably the real reason why Li Changsheng was able to break through the heaven-level life and death alley with the realm of the peak martial arts.

Knowing this, Qi An was greatly touched, reflected on his own mistakes, and immediately realized that his [Backing Boxing Method] had a big flaw, that is, it was not combined with body and footwork, and the upper and lower disjoints were out of place.

Qi An's cultivation method is [Stepping on the Moon and Chasing Stars], reaching the realm of Xiaocheng, this body method is good at long-distance movement, and can only exert its greatest effect when fleeing or chasing.

In melee combat, the role of [Moon Chasing Stars] is not very obvious, the lack of dexterous changes, it can only be used to increase the speed of movement, and it is not coordinated with the [Backing Boxing Method] in the hand, and the body method and the boxing method are completely disjointed and cannot operate harmoniously.

In fact, in the masterful martial arts, the whole body is taken as a whole, whether it is the movements of the hands or the movements of the feet, they can be combined very effectively.

And Qi An has never realized this, and the [Backing Boxing Method] created only focuses on the strength of the upper body, and the lower body does not cooperate with it, resulting in a disconnection between the two, each for its own government, hindering each other, unlike Li Changsheng's [Ghost Knife], the body is the knife, the knife is also the body, the knife is the body, the body is resistant, and the body moves with the knife, and the two are fundamentally combined into a whole, without distinguishing each other.

This principle can also be applied to the boxing method, the boxing method is the body method, and the body method is also the boxing method, the two cover each other and tolerate each other, you have me, I have you.

If you want to continue to improve, you must combine the body and footwork, effectively cooperate with the upper and lower plates, follow the boxing, and move the body to the boxing, so that it can be regarded as the real [backing boxing method].

Thinking about this, Qi An is like opening a new door to martial arts, he did not punch on the upper plate as before, move on the lower plate, but effectively combine the two, punching at the same time moving, moving while punching, boxing driving the body, and the body in turn driving the boxing, truly boxing with the body, moving the fist to, punching and body, body and fist.

In this way, the original [Backing Boxing Method], which was originally just fierce and violent, suddenly became vivid, rigid and soft, natural, there is no lack of dexterity in the mighty, and there is strength in the agility.

As a result, Qi An is no longer standing in one place, steady and steady, but like Li Changsheng, his feet are moving at any time, and his body shape is constantly changing.

After the punch and body are combined, the punch power is also greatly improved.

In the past, when Qi An punched, he used his waist to exert force, then drove his shoulders, elbows, and wrists, and finally concentrated his strength on the fist to hit out, but after integrating the body method, Qi An exerted force from his feet, along the ankle, knee, and hip in turn, and then to the waist, and then passed to the shoulder, elbow, wrist, and finally to the punch.

In this way, it is not only the upper body that exerts force, but also gathers the strength of the whole body, even including the recoil that erupts when the [Moon Chasing Stars] is stepped, and the power of the fist suddenly increases, completely crushing Li Changsheng.

Qi An, who comprehended the breakthrough in the battle, combined his fist with his body, and his understanding of martial arts reached a new level, and his strength also rose a lot, and he was no longer suppressed by Li Changsheng, but turned his body like a swimming dragon, his fist was like a landslide, and he turned defense into offense, and he fought fiercely with Li Changsheng with dynamic braking.

At this time, Qi An is no longer under Li Changsheng in terms of martial arts attainments, and his cultivation realm is also equivalent to it, Li Changsheng has no advantage at all, even if he can turn into three ghosts, the [Ghost Knife] moves are unpredictable, but after the advanced [Backing Mountain Fist Method] No longer lacks dexterity and agility, he can completely keep up with Li Changsheng's rhythm, and Qi An's defense is too strong, so he has a lot less worries, plus Qi An's attack power far exceeds that of Li Changsheng, Li Changsheng didn't dare to take Qi An's fist at all, but was gradually forced to the bottom by Qi An, and the fierce battle was difficult.

All of a sudden, the situation reversed, it was originally Li Changsheng who pressed Qi An to fight, but now it has become Qi An who pressed Li Changsheng to attack, what happened in the meantime, many people didn't figure it out, including Li Changsheng himself.

Before he started, Li Changsheng still had absolute confidence in himself, but when his knife couldn't break through Qi An's defense, he was a little frightened, but in the overall situation, he still had the advantage, and the initiative was still in his own hands, so Li Changsheng was not too nervous, the opponent's boxing technique was not a big threat to him, not to mention attacking, it would be good to be able to hold it.

But suddenly, Qi An's boxing power skyrocketed, and the cooperation with the body was intimate, no longer a stiff defense, but a punch in the position, the fist was born with him, fighting while walking, defending with the attack, both offensive and defensive, completely fast and agile, which can be called impeccable. In this way, Li Changsheng not only couldn't suppress Qi An, but lost his advantage and was suppressed by Qi An.

Could it be that he was going to lose? Li Changsheng couldn't believe that the situation would evolve like this, he was as proud as he was, the word "failure" had never appeared in his mind, he couldn't accept this result!

Seeing that the situation was getting worse and worse, Li Changsheng no longer hesitated, and finally used his own killing move. I saw him shout, and his figure turned into three again, and it was rare that he did not dodge, but launched an attack from the front and left and right sides of Qi'an at the same time, which was quite desperate and duel.

Of course, Qi An was not afraid of facing Li Changsheng head-on, he stepped forward, and drove the fist with his body, and in an instant, he made three punches in a row, the left horizontal fist, the right drill fist, and the middle was the collapse fist, respectively, facing Li Changsheng's three sword shadows.

However, what he didn't expect was that at this critical moment, a fourth ghostly figure suddenly condensed behind Qi An, and quietly swung a knife, like rain and mist, like a dream, and swept towards the back of Qi An's neck.

This knife did not bring the slightest sound of wind, and not even the miserable sword light did not bloom, and there was no trace of smoke and fire, as if the ghost knife suddenly poked out of nothingness, quietly asking for people's lives.

When many fast-eyed people saw this scene, they all exclaimed in unison, and they were shocked by Li Changsheng's strength.

It's just that the three figures are between the virtual and the real, and it is difficult to distinguish between the real and the false, which is already difficult to deal with, who knows that Li Changsheng can actually differentiate the fourth figure, and the fourth figure that appears at the end is really like a ghost shadow, his feet do not touch the ground, and he is silent, just like the mysterious assassin hidden in the shadows, at the most critical moment, he launched the most fatal blow.

However, Li Changsheng missed, and when the blade was about to cut through the back of Qi An's neck, Qi An suddenly rushed forward with a step, narrowly avoiding the cutting of the blade, and then turned around, and a palm quickly poked out, taking advantage of Li Changsheng's slight stunned opportunity, the latter grabbed Li Changsheng's long knife first.

This is the chaotic fist style of the [Backing Boxing Method], and it is also the fastest punching style.

It turned out that the three figures in front and on both sides were all fake, and Li Changsheng's true body had already sneaked behind Qi An, and launched a deadly surprise attack while Qi An was dealing with the three phantom bodies.

Qi An did not see through Li Changsheng's trick in advance, but Qi An, who was in harmony with his fist and body, would not stop in one position for a long time to leave Li Changsheng as a target, he noticed that something was wrong when he faced the three phantom bodies, and at the same time gave birth to an alarm in his heart, although he didn't know where the crisis came from, but the cautious Qi An still took advantage of the opportunity to punch with his fist, and stepped out in just one step, which was worthy of avoiding Li Changsheng's ghostly knife.

As for Qi An's turning around and punching, it was also a subconscious action, probably guessing that there was danger after being born, so without thinking too much, he quickly turned around and used a chaotic punch at the same time, and grabbed the long knife that had not yet been evacuated.
