About hundreds of thousands of years ago, there was a spatial tunnel between the Tianluo Continent and the Qingluo Continent, this spatial tunnel was no smaller than the existing spatial tunnel, it was full of instability, and this passage was extremely stable.

In this passage, although there are powerful air currents and winds shuttling between the two realms, as long as you cultivate to reach the Martial Venerable realm, you can resist the impact of these winds and air currents, and freely shuttle between the two worlds.

Moreover, this passage also has the effect of exchanging the spiritual energy of the two realms, it is precisely because the spiritual energy of the intermediate continent Qingluo Continent continues to pour into the Tianluo Continent through this channel, so the spiritual energy and cultivation environment of the Tianluo Continent in the ancient period are far stronger than now, and countless powerhouses have emerged as a result.

The Ten Great Emperors, Xuan Bing and others were the leaders who were born in this period.

However, while this passage has improved the martial arts level of the Tianluo Continent, it has also brought unprecedented disasters to the Tianluo Continent, and the Qingluo Continent, which is adjacent to the Tianluo Continent, does not want to occupy the Tianluo Continent through this passage all the time and enslave the people of the Tianluo Continent.

Although the martial arts level of the Qingluo Continent is high, but those who can pass through this passage are only strong people with martial arts and above, and the number of these strong people is limited, although they can occupy the Tianluo Continent, but they cannot completely rule the Tianluo Continent, and those martial artists of the Tianluo Continent who are active in the shadows have never stopped resisting.

Tens of thousands of years have passed, and a few Tianzong wizards finally appeared in the Tianluo Continent, and began to rebel against the Qingluo Continent, and these geniuses are the Ten Great Emperors.

Under the leadership of the Ten Emperors, the warriors of the Tianluo Continent successfully drove out the invaders of the Qingluo Continent and restored order in the Tianluo Continent.

But the Ten Great Emperors also knew that these invaders they had defeated were only a small part of the masters of the Qingluo Continent, and the Qingluo Continent would definitely send more masters to invade the Tianluo Continent in the future.

After the Ten Emperors discussed, they decided to take the initiative to enter the Qingluo Continent, and by disrupting the internal order of the Qingluo Continent, the Qingluo Continent would have no time to invade the Tianluo Continent.

In this way, the ten great emperors all entered the Qingluo Continent, and in the past thousand years, the Qingluo Continent has not invaded the Tianluo Continent again, and their strategy has taken effect.

But a thousand years later, the Ten Great Emperors retreated from the Qingluo Continent, and they were all seriously injured.

The Ten Great Emperors have fought in the Qingluo Continent for thousands of years, and each of them has made a great breakthrough in strength, but they have touched the interests of too many forces in the Qingluo Continent, and have been jointly besieged and killed by these forces.

As soon as the Ten Emperors were defeated, no one in the Tianluo Continent could resist the invasion of the powerhouses of the Qingluo Continent, and the Ten Emperors finally decided to seal this passage.

However, this passage is naturally formed, and it is so vast that it is easier said than done.

At that time, although the top ten emperors were all known as emperors, there was only one real emperor, and that was the strongest of the ten emperors, the Canglong Emperor.

The Canglong Emperor is powerful, he exhausted his cultivation before he completely sealed this passage, and from then on, no matter how high or low the cultivation level of the people in the Qingluo Continent is, no one can pass through this road and come to the Tianluo Continent.

Correspondingly, the rich aura on the Qingluo Continent can no longer be transmitted to the Tianluo Continent, the aura of the Tianluo Continent has become thinner and thinner, and the level of martial arts has plummeted, just a few hundred years, none of the martial artists in the Tianluo Continent can break through to the Martial Emperor.

After sealing this passage, the Canglong Emperor was too seriously injured and his cultivation was scattered, and he had no choice but to fall.

However, the Canglong Emperor also knew that although the passage was sealed, although it could ensure the peace of the Tianluo Continent for a while, it also greatly limited the achievements of the martial artists of the continent, and it was not a foolproof strategy after all, so he left a back hand, and this back hand was the Divine Key of the Two Realms.

The biggest role of the Divine Key of the Two Realms is that one day in the future, when there is a genius who is enough to support the safety of this continent, he will hand over the key to him, and this destined person will personally lift the seal left by the Canglong Emperor.

At that time, the passage between the two realms will be reopened, and the cultivation environment of the Tianluo Continent will also undergo tremendous changes in a short period of time.

But not long after the death of the Canglong Emperor, there was a conflict within the Ten Great Emperors, because the cultivation environment was deteriorating day by day, not only the cultivation of ordinary martial artists was affected, but even the nine of them were also affected.

Therefore, five of the remaining Nine Great Emperors advocated opening this passage immediately, allowing the Tianluo Continent to return to the state before the appearance of the Ten Great Emperors, and they would sneak into the Qingluo Continent again to cultivate, and after their cultivation was successful, they would come back to liberate the Tianluo Continent.

However, this proposal was rejected by the other three emperors, who did not want the ordinary martial artists of the Tianluo Continent to suffer any more unnecessary damage.

These three opposing emperors are Xuan Bing's father, the Demon Emperor, and the current Heavenly Sword Emperor on the Shura Continent, and the legendary Luo Sheng Emperor.

The last emperor with a neutral attitude is the friend of the Canglong Emperor, the super stargazer responsible for preserving the Divine Key of the Two Realms, the Qiankun Emperor.

Emperor Qiankun did not participate in the competition, but only agreed with the other eight emperors that whoever wins the battle between the two sides will hand over the two realms of the divine key to whomever he wants.

This civil war was extremely tragic, three of the eight emperors died directly, Xuan Bing, as the daughter of the Demon Emperor, naturally stood on her father's side, and in the end, she was also physically destroyed in this battle.

Originally, this battle would last for a long time, but an unexpected discovery stopped the war.

Because the six remaining emperors suddenly discovered that the battle between them had actually created many small spatial tunnels in the Tianluo Continent, which could lead to unknown worlds.

It was the appearance of these tunnels that allowed the five emperors to end the battle, and then they used their respective great magical powers to transform these spatial tunnels into the famous entrance to the Netherworld, as a passage for the martial artists of the Tianluo Continent to go to other continents for training, in order to make a little contribution to the improvement of the strength of the martial artists of the Tianluo Continent before the passage of the two realms was reopened.

Subsequently, the remaining six emperors went to different continents to cultivate, but unfortunately, until today, none of them appeared.

After listening to Xuan Bing's explanation, Xiao Chen said: "So that's the case, that is to say, as long as the tomb of the Canglong Emperor is opened with the Two Realms Divine Key, even if the passage between the Tianluo Continent and the Qingluo Continent is reopened, right?"

Xuan Bing nodded and said, "Yes, and only you can open this passage." ”

"Why?"

"Because you are the child of fate, before Emperor Qiankun left the Tianluo Continent, he added a ban on this two-realm divine key, and only the child of destiny can use this key to open the seal of the two realms, and no one else can. ”
