Elven hotel near the Devil's Castle.

For the past 100 years, Zhou Tong has been living in this hotel. The price of this hotel is extremely expensive, 30,000 ink stones a year, and 3 million ink stones in a hundred years. However, in the past hundred years, the amount of ink stones earned from the mission alone is close to 200 billion, and these three million ink stones are all small money.

For demon missions, the reward for one-star missions is about 100,000 ink stones, for two-star missions is 100,000 to 500,000, and for three-star missions is generally 500,000 to 500,000. However, from four stars, the increase in rewards is larger, four stars are one million to fifty million, five stars are fifty million to one billion, and six stars are one billion to ten billion.

Zhou Tong's ten extremely difficult six-star missions alone allowed him to earn nearly 100 billion ink stones.

At this moment, Zhou Tong was sitting quietly on the grass in his small courtyard.

"Hmm...... After so many years, I finally truly realized the mysteries of gravity space, and I also found the convergence point with the mysteries of the other four laws, which is rare! Zhou Tong suddenly opened his eyes, and there was a hint of joy in his eyes.

In the past hundred years, his laws of the earth have been completely fused with the four laws of the mysteries in the first fifty years—the earth element mysteries, the life force mysteries, the power mysteries, and the earth pulse mysteries. But then came the bottleneck, and the last earth movement and gravity space were stuck all the time, and there was no way to even get started.

So there is no way, for the next fifty years, Zhou Tong's earth god clone has been studying the fusion mysteries - the fusion pulse of the earth law and the fusion of the destruction rule.

And now, he finally felt the mystery of the fifth law of the law of the earth - gravity space.

"However, my previous guess was indeed correct, my talent trick should be the product of the fusion of the three laws of gravity space, strength and life force!" After really beginning to comprehend the gravity space, Zhou Tong had already realized what the last law mystery that his talent was lacking.

"Take your time, one day, I can completely merge!" Zhou Tong said secretly in his heart.

Based on Zhou Tong's own speculation, it is estimated that within five hundred years, the fusion between these five laws and mysteries will reach the limit, and only the final bottleneck is missing.

This kind of thing is the law mystery, as long as it is introduced and fits with other law mysteries, it is easy to deduce it before consummation.

Especially for people like Zhou Tong, it is extremely fast.

His soul essence is extremely powerful, a thousand times that of an ordinary median god, and his deduction speed is naturally a thousand times that of an ordinary median god; Moreover, he is also a person who has experienced other worlds, and many of the laws and mysteries have already been comprehended, and now he is just re-comprehending them in a different situation.

If it weren't for the two levels of Law Perception and Dacheng to block it, he would have been able to complete the system in a thousand years.

"But it's almost time to get around!" After pondering for a while, Zhou Tong still decided to relax a little, the way of cultivation is to relax one by one.

For more than 100 years, I have been either fighting or cultivating, and I have no time to feel the leisurely life of hell. It's also time to go out and take a look at the hell it has to offer.

Devil's Castle.

"Lord Karn!"

"Meet Lord Karn!"

Zhou Tong had just walked down from the upper floor of the Demon Castle, and suddenly looked at him with respectful eyes.

"Brother Karn, your soul is hidden to such an extent, tsk......" At this moment, a voice with a hint of magnetism sounded, and a man with purple hair and silver eyes walked in in amazement.

"City Lord!"

"Meet the Castle Lord!"

With this voice, many people reacted and immediately bowed and saluted.

"Guterres, you're here too!" Zhou Tong glanced at the purple-haired and silver-eyed man and showed a hint of a smile.

This person is none other than the city lord of Purple Cloud City, the Seven-Star Demon - Purple Cloud Demon.

The Purple Cloud Demon is a fairly ancient seven-star demon in Hell, extremely good at the laws of water and thunder, and even this city is named after his demon title.

"Guterres" is the name of the Purple Cloud Demon, but not many people know his real name, and even if they know his real name, they don't have enough strength to call him by his name openly.

In the past hundred years, Zhou Tong's fame has naturally attracted the attention of some people, including Guterres, the city lord of Purple Cloud City.

"Just come over and have a look, if you're not busy, you might as well come over and have a drink or two!" Guterres walked to the wine table not far from the hall and invited Zhou Tong.

The hall on the first floor of the Demon Castle actually doubles as a bar, dedicated to the devil drinking and chatting.

"It's good!" Zhou Tong gladly accepted the invitation.

"Two bottles of 'Blue Finney', put it on my account!!" Guterres shouted at the front desk.

Then, Guterres looked at Zhou Tong and said, "I saw you coming down from the upstairs just now, should you take the seven-star demon mission?" ”

"Not really, it's just a simple five-star guard mission." Zhou Tong shook his head.

"You've changed your sex? Why did you suddenly take on a guard mission? When to go? Where is the goal? "Guterres was shocked, Zhou Tong has been on combat missions for the past hundred years, and now he suddenly takes on escort missions?

"I'll leave in eight days, and the end will be in the sea of stars and fog. I've been fighting here for more than a hundred years, and it's useless to continue fighting in a short period of time, so it's better to look around, and maybe there will be a breakthrough! Zhou Tong smiled and poured a glass of wine, touched Guterres's wine glass, and drank it all.

"You've reached a bottleneck too!" Guterres sighed, "Oh, the bottleneck thing...... Alas, I've been stuck here for billions of years, and the fifth mysteries have never been able to find a point of convergence with other mysteries, and I don't know when I will be able to break through!! ”

"What are you anxious about? Anyway, as the lord of a city, as long as you don't provoke anyone who is too strong, you can stay like this forever, and you can break through one day. Zhou Tong said leisurely.

After a hundred years of cultivation, Zhou Tong's rules of destruction have indeed reached a bottleneck.

Although his own perception of the annihilation had been achieved, the integration with the other four major annihilations had reached the final bottleneck, and at the same time, he had no new perception and was never able to break through to the next realm.

"It's not like someone like you would say it." Guterres laughed.

Zhou Tong smiled, then changed the topic and said, "Speaking of which, I'm also leaving here, the information you collected on those super powerhouses, such as Shura, Purgatory Commander or something, as well as those relatively rare cultivation notes, I'll pay for a copy!" ”

"Haha, those things, if you want them, I'll go back and sort them out, and I'll send you a copy directly!" Guterres laughed.

He had boasted to Zhou Tong about his collections before, which were all kinds of classics that he had collected in hell for hundreds of millions of years, and even contained some super strong people's understanding of various laws and mysteries, many of which were unique books that the outside world could not see at all.

In the past, Zhou Tong didn't care much, but now that he has taken on such an escort task, he also reads books on the way to pass the time, and maybe from those unusual solitary books, he can see some possibilities for progress.

"Thank you very much!" Zhou thanked him, and then continued to drink and chat.

The two talked about Guterres's many experiences over the years, the big battles he had seen, and the changes in hell over the years......

The two drank and chatted here almost until curfew.

And in the early morning of the eighth day, Zhou Tong also said goodbye to the elf hotel where he had lived for more than 100 years, retired from the room, and went straight out of the city.
