The reason why Zhang Tie had such an idea was definitely not a whimsical pat on his head, but from his real experience and perception.

Do you remember the puppet war puppet hall under the Blood Sacrifice Temple?

When he was underground, Zhang Tie went to the hall again and again to deliberately activate those puppet war puppets, in order to hone his combat skills and martial skills. In that dangerous hall, Zhang Tie's combat skills and Martial arts have also grown by leaps and bounds in a short period of time, especially his "Candle Dragon Spear Technique", which was almost honed in that puppet hall.

For a knight and a fighter, actual combat is always the fastest way to improve their combat skills and strength. The best way for a knight to thoroughly test his combat power level and hone his combat skills and martial arts is to Fighting with other knights.

But it’s not so easy for a knight to find a few other knights to accompany him to hone his combat power. I won’t talk about those lone knights. Even among the big sects and families, there are a few more knights. When you want to hone and improve your combat skills, you can pull a bunch of knights to accompany you to practice hard without worrying about problems.

If this problem is really easy to solve, Tianjimen's Huntianbao ball will not have such a high status in Taixia.

However, although Tianjimen's Huntianbao ball can simulate reality, there is also a difference between simulation and reality. Zhang Tie also understands this, and the most important point is that Huntianbao ball is only heard in Taixia. Two, one Huntian Treasure Ball is in the Tianji Gate, the other Huntian Treasure Ball is in the Earth Elementary Realm, and ordinary people don't think about the Huntian Treasure Ball in the Tianji Gate. Except for the Knights of Tianji Gate, it is rare to hear that there are knights outside. It’s not easy for ordinary knights to try the earthy ball in the earth element world. Not only does that knight have to serve in earth element world to be eligible for use, even if it is used, it will take a long time for a team to turn. To once.

For all the knights in Taixia, this kind of resources and places to hone their combat skills in actual combat is too scarce.

Under such circumstances, Zhang Tie relied on his absolute control over the Great Desolate Cave Sky to build the first floor of the Great Desolate Cave Sky into a combat skill training ground open to all knights. What will the result be?

God Lord Baoyan, God Jianmu, Zhenjun Deyang and the others almost instantly thought of a word—hot!

No wonder Zhang Tie wants to build a castle on Yuanji Mountain. This castle is a transit station that enters the first floor of Dahuangdongtian below.

"The Demon Killing Valley, then first reserve 50 places for knights who enter the first layer of the cave to hone their combat skills every year!" God Lord Baoyan almost didn't even think about it, and said first.

"Tianjimen also first booked 50 places for knights who will enter the first layer of the cave to hone their combat skills every year!" True Monarch Deyang also immediately opened his mouth.

"Your Heavenly Secret Gate already has a chasing ball, do you want the knights to come here to hone their combat skills?"

"Hahaha, Huntian Baoqiu and the scenes of actual combat with puppets in this wild cave have their own strengths, and the two can complement each other!" Real Monarch Deyang looked at Zhang Tie, his eyes narrowed into a line with a smile, "Maybe In this regard, Tianjimen's Huntian Treasure Ball can also be shared with Tielongzong!"

"I don't know what price a knight needs to pay when he enters to practice?" Jianmu Shenjun asked cautiously.

What Zhang Tie said also made Jianmu Shenjun a heartbeat, but after all, the Jiang family couldn’t compare to martial arts like Moshagu and Tianjimen. They didn’t dare to place an order without even asking about the “price”, because they might get it. It's awkward.

"I haven't thought about the specifics yet. I think the price will generally be determined according to the difficulty of the different areas set in the first layer of the cave and the length of stay!" Zhang Tie smiled, "This price will not be cheap. But it’s not an exaggeration for the knights. My idea is that most knights can afford to consume. Specifically, after the elders of the Iron Dragon Sect arrive, I will discuss with them before doing it. Decided!"

Hearing what Zhang Tie said, Jianmu Shenjun suddenly felt relieved. Since Zhang Tie said that most knights can afford it, then the knights of the Jiang family should also be able to afford it. Don’t worry too much. "In this case, our Jiang family will also book five places first!"

"Okay, no problem!" Zhang Tie generously agreed, and then asked God Lord Baoyan and True Lord Deyang curiously, "You two schools also have a cave, you can also be in your own cave with this method. Why would you think of coming here again?"

"The location of each sect of the cave and the resource treasures in the cave are the top secrets of each sect, and the so-called cave is not all puppet war puppets in the cave, and there is no puppet war puppet in the cave of Tianji Gate. , Many big sects’ caves do not necessarily have them. Even if there are puppet war puppets in the caves of some sects, the number of puppet war puppets in those caves or the space and other aspects of the conditions cannot be matched Compared with the Great Desolate Cave Sky, this Great Desolate Cave Sky, if only the number of puppet battle puppets and the Tower of Time, is definitely second to none in Taixia!" True Monarch Deyang said to Zhang Tie seriously, and Lord Baoyan nodded in agreement. .

When True Monarch Deyang said so, Zhang Tie understood. He turned to Bai Runshan, "San Shu, Guangnan Palace has 50 knights each year that can enter the Great Desolate Cave for free to practice, don't know if it is enough?"

"Enough, of course it's enough..." Bai Runshan laughed and beamed. The 50 knights' training quota, Guangnan Palace actually can't be used up. Since Zhang Tie said so, the extra knight quotas are in Guangzhou. In the hands of Nanwangfu, this will naturally become a resource that Guangnanwangfu can flexibly adjust and can play a great role. "It's just that the name of this Great Desolate Dongtian will also be changed. I am afraid it will be called Tielong Dongtian in the future!"

"Yes, this Great Desolate Cave Sky will be called Tielong Cave Sky in the future!" The other knights were nodding. The name of this Cave Sky naturally followed the owner's name.

"By the way, this castle has no name yet!" Bai Suxian shook Zhang Tie's hand and said.

Zhang Tie thought for a while, "This is called Zhigebao. It can be regarded as the outer courtyard of the Tielongzong in Southern Xinjiang. The human knights who come here, as long as they are human knights, whether they are Chinese or foreign, or even barbarians. When I came here, I treat them equally. Any grudges between the knights are forbidden to fight within the scope of Zhigebao. Anyone who does this here will be forbidden to enter the Iron Dragon Cave for life, and it is regarded as iron to me. Longzong’s provocation, my Iron Dragonzong will definitely punish!"

"Zhigebao, stop Ge for Wu, stop Ge Xiuwu, good, this name is good!" Bai Runshan praised.

...

Two hours later, the craftsmen boarded the airship again and left here, and after they left, there were 3147 more craftsmen's names on the walls of the new castle, all of which were neatly arranged. Left on the wall of the castle, some of those names were in Chinese, some were in Hebrew, and some were in characters that Zhang Tie didn't know.

A few days later, the flying boats from Demon Killing Valley and Tianjimen arrived, and after another two days, the flying boats of the Iron Dragon Sect finally arrived...
