Although it was difficult for Su Mu to instantly discern whether the attacker's realm was higher than his own.

But with his half-baked turnaround step, Su Mu didn't dare to entangle too much at all.

And at this moment, the attackers are still in the shadows after all. And the group of mercenaries who were guarding their employers obviously wouldn't take any special risks to help Su Mu.

Therefore, Su Mu's only choice now is to stay away from the person in front of him as soon as possible and immediately retreat to the mercenary group.

After judging the pros and cons in an instant, Su Mu did not hesitate at all.

directly swept his giant sword out horizontally, forcing the other party to immediately avoid the edge.

And taking advantage of the moment when the other party subconsciously retreated, Su Mu had already turned the parallelogram under his feet into the most sharp double Ling cone.

With the help of the two points farthest away from the diamond, the long-distance transfer of several meters is carried out in an instant.

With Su Mu's actions, the figure that had just attacked him really didn't have time to stop Su Mu's evacuation, and was instantly thrown out of the usual combat range by Su Mu.

In this way, as long as the realm of the two is almost the same, the other party will no longer be able to catch up with Su Mu's footsteps.

......

However, it was also in Su Mu that he was secretly glad that he had just successfully withdrawn, and he hadn't even had time to run to the gathering place of the mercenaries.

An imminent sound of breaking wind immediately sounded from the back of Su Mu's head.

For the crisis that came from this fight, and it came so quickly, Su Mu didn't dare to underestimate it at all.

At this moment, Su Mu was almost instinctive, and in an instant, through the step-by-step of the turnaround step, he gave the giant sword full of division "Royal Character Formula" in front of him.

And Su Mu's move obviously succeeded in saving his life.

As Su Mu had just finished this defense, a bright and sharp metal impact spark had already bloomed on the sword body of the rung.

And even though Su Mu had used the powerful Imperial Character Technique, the huge shock from the sword body still made Su Mu almost unable to hold the hilt of the sword.

Shocked in his heart, Su Mu didn't dare to act rashly.

Immediately, he firmly grasped the heavy sword in his hand and stuck in place.

It was not until this moment that through the fireworks generated by the previous impact, the scene in front of Su Mu's eyes finally flashed clear in an instant. And through the picture captured in this moment, Su Mu also really saw the appearance of the pursuer.

But such a hurried glance also made Su Mu feel even more desperate.

Because the attacker who was in front of Su Mu at this moment was actually not a strong warrior with a heavy weapon, but an extremely slender woman.

Even the weapon she held in her hand was only a dark thin sword with a dull color.

But even such a thin blade that is less than two fingers can bring such a powerful impact. Then this person's current realm is obviously much higher than the current Su Mu.

......

Seeing that Su Mu blocked the blow she was full of, the woman did not seem overly surprised, but raised her thin blade again with her backhand, and stabbed at Su Mu's tight defense one after another.

And the woman's attacks are already so straightforward and direct, and she doesn't have the slightest intention of hiding her own means.

Therefore, Su Mu, who was defending with a front, quickly discovered it at this moment...... This woman's offensive methods are actually not so mysterious, she uses the double word trick used to explode.

However, the real weirdness is that explosive methods such as the double word recipe obviously can't be used for a long time, otherwise sooner or later, they will quickly exhaust their own qi.

But at this time, the woman obviously used the explosion of the double word formula with every blow, and she had no intention of exhausting it at all.

In contrast, Su Mu, who also used the Imperial Character Technique for strong prevention, already felt that his Qi was passing rapidly.

If it continues like this, it will not be able to wait for the other party to break through Su Mu's defense, and Su Mu will already be exhausted and defeated.

And the woman who kept attacking obviously noticed this as well.

Therefore, she did not stop at this time, and hit Su Mu's heavy sword like a raindrop, causing the sparks from the collision between the metals to splash down quickly, and also rapidly consume Su Mu's already small amount of Qi.

According to this situation, it seems that Su Muna's inevitable defeat is only a matter of time.

......

However, as the woman stabbed again and again, time was also flowing little by little.

But an extremely strange scene appeared in front of the woman's eyes slightly.

Su Mu, who should have been exhausted and defeated a long time ago at this moment, was still stubbornly maintaining his own defenses, and even still used the imperial character technique that consumed a lot of energy.

A trace of weird smell was finally noticed by the woman who kept attacking.

Therefore, this woman, who was extremely experienced in combat, had already withdrawn several positions as soon as she noticed the strangeness.

And the woman who retreated violently looked at Su Mu's expression coldly, as if she wanted to get a glimpse of what was going on from his face.

Until this moment, the woman had neatly retracted the attack and no longer continued to entangle with Su Mu.

An expression of slight regret finally appeared on Su Mu's face.

It seems that Su Mu's previous nervousness and fear all stemmed from his deliberate play. And the reason why Su Mu performed like this was precisely to let the woman continue to feed him.

The woman in front of her is stronger than Su Mu in the realm, this is obviously an undoubted fact.

And Su Mu, under her attack, can only be strictly defended, which is also an indisputable truth.

However, in addition to the premise that these two points are very different, the reason that really makes women helpless is precisely the method that women use to attack.

As we all know, if you repeatedly use an explosive fighting technique like the Double Character Technique, no matter how rich your own Qi is, you will still not be able to support such unbridled consumption.

But in fact, the woman in front of Su Mu, in order to make up for the difference in the weight of her weapons with Su Mu, has been using the double word trick to slash.

In this case, she must know some way to reduce her Qi consumption.

And if this matter is changed to someone else, it may not be able to see through the essence of this ability.

But after all, Su Mu is familiar with the entire fighting skill system, and even knows the direction of the advancement of fighting skills. Therefore, to restore the root cause from the phenomenon in front of you is simply such a smooth thing.

Not to mention, in the previous continuous entanglement, the woman also gave Su Mu countless opportunities to steal teachers.

"It turns out that as long as the double character formula and the royal character formula are performed according to a certain law, they can also be carried forward in the superposition of each other, thus saving a lot of Qi energy consumption. ”

Su Mu looked at the woman lightly, and didn't mind revealing that he was secretly learning the other party's fighting skills.

And when the woman heard that Su Mu was so lightweight, she exposed the essence of this fourth-order fighting technique. Naturally, she realized in an instant that Su Mu really comprehended her "Double Nine Enhancement Technique".

Because in the rules of this world, addition is a technique of repeatedly superimposing forces.

Each time you release a minimum amount of Qi, it can be stacked with the power previously released, creating an increasingly powerful force.

But in fact, there is another way, which can also allow the multiplication to continue to inherit the energy of the last time in the repeated superposition, so as to maintain a strong attack with minimal consumption.

The premise of this is to be extremely familiar with the "complex" changes in multiplication, so that every tiny multiplier you pay can be mutually enhanced with the residual power after the explosion, so as to restore the original strength intensity.

Therefore, the real difficulty of the Double Nine Enhancement Technique lies in how to grasp the derivative relationship between it.

However, this question may require continuous attempts to summarize this question for the martial artists of the brain hole world. But for Su Mu, who had already guessed the essence of the Double Nine Enhancement Technique, there was no difficulty at all.

Because there is only one possibility that allows people to quickly grasp certain rules of multiplication and division, and is clear enough to show their correspondence, there is obviously only one possibility:

That thing is exactly the textbook content that elementary school students are required to memorize in a nightmare...... Ninety-nine multiplication table!
