Seeing Gang Kui and Gang Lan hanging upside down on the wooden pole like two little monkeys, Jiang Lingxuan giggled with delight.

Sun Muqing also peeked out and asked, "Ye Feng, is this kind of cultivation effective?"

"Of course it's useful."

Night Breeze nodded with great confidence.

The method that Gangkui and Ganglan are currently practicing was devised by Yefeng. Yefeng is essentially using Gangkui and Ganglan as experimental subjects.

However, it turned out that the method Ye Feng came up with did work.

By nightfall, Gangkui and Ganglan had broken through to the fourth level of the Opening Wheel Realm.

Such a rate of improvement is undeniably fast.

Now, Gonchar is no match for Gangque and Ganglan at all. Although they have never sparred, Nightwind is very confident in this.

Even Gangdu Ning couldn't defeat either Gangkui or Ganglan.

Before we knew it, ten days had passed.

Gangkui and Ganglan finally reached the ninth level of the Opening Wheel Realm.

Having reached this stage of cultivation, Gang Kui and Gang Lan have successfully completed the goals set for them by Ye Feng.

But his training came to a complete end after that.

The possibility of Gang Kui and Gang Lan breaking through to the Separation and Union Realm is extremely small, which is precisely the drawback of the quick-success method of cultivating the Meridian Opening and Tendon Expanding Spiritual Body Technique.

Even if they manage to break through to the Separation and Union Realm in the future, they will not be able to break through to the True Essence Realm.

Their potential has been completely locked, and even switching to other cultivation methods won't help.

Unless they are given rare and precious materials to re-temper their bodies and then start cultivating from scratch, but are there that many rare and precious materials in the world?

Night Wind didn't think Gangkui and Ganglan could be so lucky.

After a ten-day journey, the Black Tower tribe finally arrived near the Holy City.

The Black Tower tribe then set up camp here and erected all the tents.

"Can't we enter the Holy City?" Night Wind asked.

As he spoke, Ye Feng turned and looked in the direction of the Holy City.

Just a few miles to the southwest, there was a magnificent city.

The city is predominantly gray-black, and its walls are constructed of massive stone bricks, giving it a grand and imposing appearance with a strong sense of history.

The holy city must have existed for a very long time, perhaps even thousands of years.

“Our tribe is not allowed to enter the Holy City. Although the Holy City is very large, there are too many tribes. If all the tribes on the plateau were to enter the Holy City, it certainly wouldn’t be able to accommodate so many people. Only the top ten tribes on the plateau can settle in the Holy City, and only the tribes ranked eleventh to one hundredth are qualified to reside near the Holy City for a long time,” Gangkui said.

“Master, look, other tribes are also choosing a place to set up camp outside the Holy City, just like our Black Tower tribe,” Ganglan said, pointing into the distance.

Night Wind turned his head and saw that there were indeed tribes like the Black Tower tribe, choosing a place with abundant water and grass outside the Holy City to set up camp.

“That looks like the Minglei tribe?” Gangkui said.

“Yes, it is indeed the Minglei tribe. I saw Lei Yun, the chieftain of the Minglei tribe,” Gang Lan nodded.

"Is the Minglei tribe very powerful?" Ye Feng asked with a smile.

“The Minglei tribe is indeed very powerful, ranking very high and very close to the top 100. Perhaps in this Holy City Grand Competition, the Minglei tribe can enter the top 100 and obtain the qualification to be stationed near the Holy City,” Gang Kui nodded.

Night Breeze nodded, a thoughtful look on his face.

Suddenly remembering something, Ye Feng laughed and said, "Let's go, let's go to the Holy City now. Although your tribe can't settle in the Holy City, surely a few of us can go in and take a look?"

"Of course, that's no problem."

Ganglan nodded happily, and then together with Gangkui, they followed the night wind toward the Holy City.

"Let's go too!"

Jiang Lingxuan chased after him out of the tent.

Ye Feng shook his head and said, "Ling Xuan, you should wait for me here with Mu Qing. I won't stay in the Holy City for too long."

"Oh, okay then."

Jiang Lingxuan nodded obediently and returned to the tent.

The holy city was crowded with people, and everywhere was a scene of prosperity.

However, Ye Feng was not in the mood to appreciate the bustling scene in the Holy City. What Ye Feng was thinking about now was how to join the Underworld Sect.

The Netherworld Sect is the actual administrator of the Holy City and the largest and strongest force in the entire Netherworld Plateau.

Now that I am in the Holy City, I should naturally consider joining the Underworld Sect.

Ye Feng didn't ponder this alone; he looked at Gang Kui and Gang Lan and asked, "You two should know something about the Underworld Sect, right?"

Gang Kui laughed and said, "Of course! The Netherworld Sect is the largest and strongest sect on our Netherworld Plateau. How could we not know about the Netherworld Sect? Master, do you want to join the Netherworld Sect?"

Gangkui and Ganglan looked at Yefeng curiously, their big eyes blinking.

Although Ye Feng emphasized that he was not their master, Gang Kui and Gang Lan did not listen and always referred to Ye Feng as their master.

Night Wind nodded and said, "I do intend to join the Underworld Sect."

"Just as I thought!"

"Grandpa is right!"

Gangque and Ganglan both shouted.

Night Wind looked surprised and asked, "Your grandfather? You mean the clan leader Gang Duning, right? Did he guess that I was going to join the Underworld Sect?"

“That’s right. Grandpa said you have a mysterious background and are very strong. Someone like you would never join our Black Tower tribe, so your target is most likely the Netherworld Sect,” Gang Lan said with a smile.

Night Breeze then realized that his attempt to keep a low profile had already been seen through.

But there's nothing we can do about it.

Along the way, the night wind has left too many traces.

Slay the Chain Armored Beasts and teach Gangque and Ganglan how to train.

These traces are too numerous and too obvious.

Gonchar and Gangduning aren't fools. If they couldn't guess that Yefeng was a very powerful martial artist, they would be incredibly stupid.

“Master, if you want to join the Underworld Sect, the easiest way is to challenge the Holy City Warriors,” Ganglan said.

"Generate a fighter?" Night Wind's face showed interest.

Ganglan nodded vigorously: "That's right. The Holy City Warriors are all from the Underworld Sect. They are people sent by the Underworld Sect to manage the security of the Holy City. If you challenge a Holy City Warrior and defeat him, the Underworld Sect will naturally take notice of you, and the elders of the Underworld Sect may even recommend you to join the Underworld Sect."

Upon hearing this, Ye Feng's face showed a thoughtful expression.

"Is there any other way?" Night Wind asked again.

“Of course there are, but other methods… require some other skills. If you know alchemy and weapon crafting, then you can find a place in the Holy City to show off your skills. As long as you become famous, the elders of the Netherworld Sect will naturally come looking for you,” Gang Kui continued.
