Combat is indeed the best way to improve people's combat power, especially the battle between life and death.

What is the most difficult thing for a martial artist to cultivate? It is to comprehend the origin and mystery of the laws of heaven and earth, and the power of heaven and earth and the soul can be piled up with resources, but the laws of heaven and earth and the origin of the mystery must rely on oneself to comprehend.

Martial artists can often stimulate their potential in life and death battles, and the speed of their minds at that moment is tens of thousands of times, and many things that they can't figure out may be integrated at that moment, and they may have an epiphany.

As long as you can comprehend the laws of heaven and earth, and get started with the mystery of the origin, the rest is not a problem. The four great emperors and many big families opened up the primordial secret realms controlled by each family, the Daotian Secret Realm, and even the Hongmeng Secret Realm. As long as you have combat merits, as long as you can comprehend the origin and meaning of the law, you can enter the major secret realms for free to cultivate heavenly power and improve the speed of comprehension, and the four emperors will also give you a large number of soul elixirs to help you quickly improve your realm and improve your combat power!

The war continued, and some hidden powerhouses in the human race were born, and these strong men were quickly promoted and reused, and the six armies continued to expand, adding many titles and official positions.

During this time, many strong people poured out, and many unknown warriors were also famous all over the world.

Among them, the most famous are four people, the first is a strong man who is hidden in the world, whose combat power is comparable to that of a sword slave, who joined the Yan Emperor Army and was directly appointed as a general.

The second is a genius from the water world, this person is still a woman, named Xia Yu. is a very young woman, and it is estimated that she is not as old as Mad Amber. What she cultivates is a very magical mystery, the mysteries of light, which is inherently restrained by the underworld's underworld, although she only has the combat power of the king level, but because of her outstanding military achievements, she has been promoted to seven levels in a row, and at this moment she is already a great general king in the Blue Emperor Army.

The third is the eagle king, the eagle king fought very hard, the battle power of the fierce and fearless increased very quickly, the army he led the casualty rate was the highest, but the battle exploits made many troops breathtaking, the eaglet king was promoted to the general king by Wei Tianwang, and commanded an army alone.

The fourth is Yi Piaopiao, Yi Piaopiao has no army under him, only ten king-level, and the task of these ten king-level is only to protect her.

She has an army of Chaos Beasts under her command, all of them are tens of thousands of years of Hongmeng-level Chaos Beasts, the number has reached 10,000, and this army is now the strongest army in combat effectiveness among all the group armies in the entire Heavenly Realm.

The combat power of the Chaos Beast for tens of millions of years is comparable to the king level, in other words, the clothes are fluttering with 10,000 king levels, just ask which single army has such a powerful military power?

Yi Piaopiao's identity information was blocked, after all, she was Jiang Yi's mother, but the name Jiang Yi was humiliated by the Qingdi Dao Family, the Crazy Emperor and others. Therefore, Yi Piaopiao's identity is very mysterious, and she has become the goddess in the hearts of many ordinary young sons, and the folk have also given it the title of "Goddess of Animal Taming".

......

Time has been spent in countless battles, slipped away in the defeat of the underworld again and again, and the great victory of the human race.

One year!

In just one year, the Terran army has advanced hundreds of millions of miles westward, recovering hundreds of thousands of secret realms, and the army in front has already reached the vicinity of the Tiangang Realm and the Heavenly Spirit Realm.

The thirty-six Heavenly Kings teamed up to destroy the two Hades Kings, and the Four Great Emperors once again struck to kill one of the three Hades Kings in the Tiangang Realm, and also killed several ordinary Hades Kings. The underworld has been defeated and retreated, and now it is shrinking in an all-round way, stubbornly guarding the Heavenly Spirit Realm and the Tiangang Realm, and does not dare to take the lead.

The Terran army didn't dare to go deeper, because many Hades in the underworld came to reinforce them, the top ten Hades were seven more than the Emperor-level Hades, and the combat power was even more than the pseudo-emperor-level Hades were teleported over hundreds...

Both sides suffered heavy casualties this time, so there was a tacit understanding to temporarily truce!

The human race killed at least tens of millions of warriors in this battle, but to the relief of the major families of the Four Emperors, the number of strong men who rose this time was a hundred times that of the previous ones.

There are more than 20 feudal kings who have broken through the pseudo-emperor level, and the number of strong people who have broken through the feudal king level has reached nearly a thousand, this is only a year, and war is really the best way to improve combat power.

A year is a short time.

But the population base of the Terrans is large, and a lot of people can be bred in a year, and the Terrans have never lacked low-level warriors, what they lack is the strong. Low-level martial artists can be cultivated and manufactured in batches, but strong ones cannot be manufactured, so they can only break through by themselves.

So although there were heavy casualties this time, the human race was still greatly excited, and countless people also shouted slogans for the four emperors to lead the army to counterattack the Tiangang Realm, the Heavenly Spirit Realm, recover all the continents, drive the underworld back to the underworld, and suppress it forever.

The underworld has long stopped searching for Jiang Yi and the others, and even at this moment, the underworld doesn't care about those underworlds and human races. The underworld has been defeated one after another to the Tiangang Realm and the Heavenly Spirit Realm, and the biggest enemy at present is the Qingdi Clan, and those few are just small characters.

Of course...

They couldn't find it even if they wanted to find it, Jiang Yi was hiding in the source of fire, and no Hades dared to approach it at all. Those Hades were all in the city and would not come out to wander around, so Jiang Yi stayed in it very comfortably for a year, and realized the mystery of thunder and lightning for a whole year!

What makes Jiang Yi desperate is that after a year of understanding, this thunder and lightning has not yet been completed, and even he feels that he has only realized the tip of the iceberg in the mystery of this thunder and lightning.

Jiang Yi himself felt a little broken, more than a year had passed since ten years, but he didn't understand a single mystery. He also had to comprehend the five original mysteries, and he also had to fuse the seven original mysteries together.

When the ten years are up, with Chi Hong's character, he will definitely leave with the Fire Dragon Sword immediately, and as soon as the Fire Dragon Sword leaves the Fire Dragon Ball is gone, he will not be able to continue to lurk in the source of fire.

According to the agreement, the Emperor Tianfeng wants to return his freedom, not to mention whether the Emperor Tianfeng will kill him, even if the Emperor Tianfeng leaves him, without the Emperor Tianfeng, he will not be able to come out of the Tiangang Realm, and can only wait for death......

"Haven't realized it yet?"

After Jiang Yi stopped cultivating, he sat with bitterness on his face, and Chi Hong's eyes came out of the flames. His eyes were full of surprise, and he had never heard of Jiang Yi's situation.

Since Jiang Yi can reach such a state at such an age, it proves that he is not badly talented, this is not his problem, but the problem of this thunder and lightning mystery.

"Forget it, don't get involved!" Chi Hong paused and said in a deep voice: "You can rest and get ready to go out." ”

"Get out?"

Jiang Yi was stunned, and then asked in surprise: "Lord Chihong, can you go back?"

"Hmm!"

Chi Hong nodded and said, "The news I found out about the counterattack of the Terran army has now reached the vicinity of the Tiangang Realm and the Heavenly Spirit Realm. Recently, the army of the underworld has been continuously teleported to the Tiangang realm, and the emperor-level Hades have come to seven, and it is estimated that a big war will break out soon, so you take the opportunity to blend into the army of the underworld and go out, and then mix into the army of the human race and go back. ”

Chi Hong paused for a moment and continued: "Since you have not realized this mystery for so long, don't comprehend it for the time being, time is pressing, you should sneak back to the Tianhong Realm first, find the remaining remnants of the Fire Dragon Sword, and go to the major secret realms by the way to take a walk and comprehend the other origin mysteries." It is very likely that the Immortal Emperor will be born within ten years, if you don't reach the Emperor level and reshape the Heavenly Emperor Divine Weapon, the human race and the demon race will be finished..."
