For the next period of time, Lu Tong barely left school again, and the clone was not in a hurry to expand his territory.

He now has enough credits, and his doppelganger has also stocked up on sufficient food, so it is naturally the most important thing to practice penance behind closed doors.

The key is that Lutong is still in the stage of high-speed improvement, and it is advancing by leaps and bounds all the time, and there is no need to go out to experience.

After initially comprehending the knife momentum, Lu Tong's stacked wave knife technique was the second, and it also improved more and more rapidly.

No one could have imagined how terrible Lu Tong's entry during this period of time was.

On December 12, Lu Tong's sword momentum made a major breakthrough and successfully stepped into the second day, and the range of his sword momentum expanded to ten meters around his body.

On December 18, Lu Tong's human body qi and blood value reached 10,000, which is the peak of the Three Realms, and there was no way to advance.

Correspondingly, the qi and blood value of the turtle clone is as high as 100,000, which is comparable to the foreign beasts in the early and middle stages of the ordinary Five Realms.

On December 21, his second stacking wave knife technique was finally completed, and he slashed out the eightfold dark energy with one sword.

It was also on this night that the turtle clone struck out again, killing the mutant octopus of the Five Realms with three claws, and took charge of the wider sea territory.

"The key to breaking through the three realms and the four realms lies in the third level of the Stacking Waves Knife Method."

After the stagnation of cultivation, Lu Tong had clearly felt the shackles of breakthrough.

If he can't break through the realm, his human body and turtle clone, qi and blood will stagnate.

As for the method of breaking through, the master had already told him, that is, to find it from the third layer of the Stacking Wave Sword Method.

The second realm breaks the third realm, and it is necessary to initially master the dark energy before it can enter the bones.

And the three realms break the four realms, what is needed is that the bright and dark energies are consistent, practice and transform the strength, and then the qi and blood penetrate the body, and begin to refine the five internal organs in the body.

"This is also the third key point of the Stacking Wave Knife Technique, mastering and mastering the strength."

It sounds mysterious, but through the interpretation of the exercises, there are traces to follow.

The third entry point of the Stacked Wave Dao Method is to turn from darkness to light, and finally achieve the harmony of light and dark.

In other words, Lu Tong needs to be able to wield eight layers of dark energy at the same time, and at the same time, he can slash out two layers of bright power.

In other words, at the same time as a double sword, each sword power contains eight layers of dark energy.

This is the blend of bright energy and dark energy, and the difficulty is much greater than that of dark energy or light energy alone.

Correspondingly, once this method is mastered, its power in actual combat will also skyrocket exponentially.

With a knife out, the bright and dark energy are intertwined, difficult to distinguish, and superimposed, how to defend?

This step requires extremely high control of force, especially the best exercises such as the Stacking Wave Knife Method, which is even more difficult.

If it weren't for Lu Tong's assistance from the Stacked Waves Visualization Diagram, and the sword momentum reaching the Double Heaven, I'm afraid it would be difficult for him to get a glimpse of the door in a short period of time.

"Now that I've found a way, what I need is to constantly adjust the fineness of force control and touch the balance point again and again."

Lu Tong was happy in his heart, although it still needed some time to settle, but as long as there was progress, he had confidence and patience.

In order to speed up this process, Lu Tong will also squeeze out two hours a day to fight against virtual opponents in the virtual world.

Although he was often abused, the effect was also very significant, and on December 27, he finally ushered in a key breakthrough again.

In the cultivation room, Lu Tong slashed out, and saw two misty knife shadows, which landed on the two arms of the robot in no particular order.

Boom!

Boom!

The two muffled sounds echoed in the cultivation room almost in no particular order, and then looked at the two arms of the fourth-level robot, which turned into slag and floated to the ground.

"Another scrap!" Lu Tong sighed.

But before he had time to feel distressed, he had already put away his knife and sat on the ground and started a new round of breakthroughs.

The time to break through the four realms is now.

The qi and blood in the body flowed rolling, and under Lu Tong's fine control, it began to penetrate into the internal organs step by step.

If he didn't have a preliminary grasp of chemical strength, he would never be able to do this, and he might even hurt his fragile organs.

In history, many people who wanted to forcibly break through the realm did so because of this step, or they left themselves with irreparable wounds, and their life expectancy was greatly reduced.

And Lu Tong's step, because of his solid foundation, went very smoothly.

By the time his qi and blood had traveled through the internal organs, the sky was already bright.

I haven't slept all night, but Lu Tong's spirit is unprecedentedly full, and he feels that his whole body seems to have endless strength.

Between breaths, it is even longer and more powerful, which is completely different from before the breakthrough.

"The viscera has only been initially refined, but I didn't expect it to change so much for me." Lu Tong secretly exclaimed.

Long breathing, strong heartbeat, and other phenomena are naturally the result of the tempering of the lungs and heart.

Before the Four Realms, the internal organs of the body were the biggest weakness of a martial artist, and once they were attacked by the dark energy, they would inevitably leave internal injuries.

And after tempering, the martial artist will naturally have more means to resist the dark energy, and the defense and recovery power of the internal organs will be greatly enhanced.

The five internal organs are the foundation of the human body's operation, and there are too many benefits after quenching.

Lu Tong didn't have time to dig deeper, but after sending out a challenge at the end of the month, he teleported to the cave of the turtle clone.

At this time, the turtle clone, because of the breakthrough of the human body, has also completed another evolution.

Its body was thirty meters long, its limbs grew thicker and stronger, its head and tail became a little longer, and its black scales shimmered with a cold glow.

The turtle clone of the fourth realm was so powerful that Lu Tong, the main body, felt bursts of heart palpitations.

Lu Tong had no doubt that if the current turtle clone encountered the previous octopus monster, one move would be enough to destroy it.

"Even if it is a strange beast at the peak of the late stage of the Five Realms, the turtle clone has an eighty percent victory rate." Lu Tong gave birth to confidence in his heart.

In addition to evolving and growing, the turtle clone has once again awakened a new bloodline ability.

And this ability can be said to be the same as the last water wave armor, and Lu Tong called it water control.

The ability to be simple and direct is to control the moisture of the outside world for its own use.

As for the specific range and intensity of control, it seems to be related to the potential class that you have mastered.

"Is it because I comprehended the potential first, and the clone can awaken this ability?"

"Or is it that the clone could have awakened this kind of ability...... which is similar to potential" Lu Tong couldn't figure it out.

But in any case, he was extremely pleased, because his human body also obtained this ability to control water at the same time.

"If it can be used properly, it will definitely have an unimaginable effect in battle." Lu Tong is already looking forward to it.
