Chapter 128：Source Qi vein

The ancient castle where the galaxy population resides has a towering tower in the middle, which is twenty-one stories high. This tower is a cultivation tower, connecting the earth's vital energy. 

In Tianyi Academy, there are four such cultivation towers in total. There is one each for the Noble Faction and the Assassination Faction. The fourth one is located on the training ground of Tianyi Academy. That tower is the tallest one. 

"Lin Feng, during the days when you were away, the first instruction given to us by the college teachers was that we should spend three months practicing in the cultivation tower." 

At this moment, Lin Feng and others were standing beneath the training tower, looking up at this magnificent training tower. Yuan Shan then said, "Underneath this training tower is said to be a primordial energy earth meridian, possessing an extremely powerful and continuous flow of primordial energy from the universe. It is called the earth meridian qi, and this training tower is built upon the primordial energy earth meridian. Each of the training rooms inside the tower has been fortified by an array, and it has much more intense primordial energy than the outside world, making it very suitable for training." 

"Connecting the vital energy and the ancestral lineages, Tianyi Academy has managed to monopolize four locations and build four cultivation towers there. What a grand gesture!" 

Lin Feng was standing on the ground beside the cultivation tower, and he could feel the surging fluctuations of the primordial qi of heaven and earth. He murmured softly. 

"Of course, apart from the inner court of the royal residence where the royal family lives, Tianyi Academy has the most vital energy channels. Even the Snow Moon Holy Temple that was established on that day only has two vital energy channels, and they were forcibly occupied. As for other places outside the imperial city, vital energy channels are rarely found there. Even those major clans are the same. The imperial city gathers many powerful individuals because it has abundant vital energy channels." 

Lin Feng gave a slight nod. The Yuan Qi Gezhi was the place that martial cultivators yearned for most. Even the Yunhai Sect didn't have a single Yuan Qi Gezhi at that time. 

"It seems that Tianyi College is more terrifying than we imagined." 

Lin Feng inwardly thought to himself, "Although Tianyi Academy doesn't have a prominent reputation, it doesn't mean its strength is lacking. And that's because of the way it recruits disciples and the people it cultivates." 

To enter the academy, one needs a recommendation letter. This in itself is a major restriction. Besides, the three types of people the academy trains may all end up on the battlefield, becoming nobles or assassins, and thus remain unknown to the outside world. 

A group of people entered the cultivation tower. They saw that the first floor of this tower was relatively spacious. In the middle was an open area. There were eight cultivation rooms on the four sides, all in a closed state and being used for cultivation by someone. 

Lin Feng stood on the ground of this cultivation tower, and was able to clearly sense the surging elemental energy fluctuations coming from beneath his feet. It was terrifying. 

"Let's go up. The first to the tenth levels of the Cultivation Tower are surely out of our reach. We must at least step into the eleventh level or even higher." 

Yuan Shan said to Lin Feng, "This cultivation tower is not the one with the higher level is better, but the one with the lower level is better." 

Because the closer one gets to the bottom, the closer one is to the source of primordial energy and vital force. The natural essence of primordial energy and vital force becomes more and more concentrated the closer one gets to the bottom. And the higher one goes, the more diluted the primordial energy and vital force become. 

Lin Feng's eyes flickered for a moment, then he nodded and walked up the middle staircase towards the upper floors of the cultivation tower. 

The higher up one goes, not only does the essence of heaven and earth become thinner and thinner, but even the space becomes increasingly narrow. The area of the open space is small, and the area of the stone chamber is also very small. 

When Lin Feng reached the tenth floor, he noticed that the eight training rooms were of the same size as each other. They were probably only large enough for two people to stand in. It was very inconvenient for them to move around. Even the central open space could only accommodate about twenty people. Compared with the spaciousness of the first floor, it was a huge difference. 

Moreover, on this already cramped patch of ground, there was still a young man in black sitting there, his eyes tightly closed. 

"What is he doing this for?" 

Lin Feng's gaze flickered with a hint of confusion. On the tenth floor, there was indeed an empty cultivation room. Nobody was there. This person had a cultivation room but didn't go in. Instead, they sat outside. 

Yuan Shan's eyes flickered for a moment, then he gave a cold snort and murmured softly, "To practice cultivation in the cultivation room, one needs Yuan Stones. But many people don't have Yuan Stones on them. Or if they do, they are reluctant to take them out and want to use others' instead." 

Hearing Yuan Shan's somewhat disgruntled voice, Lin Feng's gaze slightly tightened. He used the words of others? 

"It's like this: once others have opened the cultivation chamber with Yuan Shi, they will immediately seize it." 

Yuan Shan said coldly, and at that moment, the black-clad young man who had been sitting with his eyes closed suddenly opened them. His gaze was filled with cold light as it swept over Yuan Shan. 

"Since you know that, why bother saying all this nonsense? There's a meditation room over there. Feel free to use it if you dare, but if you don't, get on up there!" 

The man in black spoke coldly, his tone extremely unkind. 

Lin Feng and others' gazes slightly narrowed. Standing beside him, Jing Yun said, "Yuan Shan, won't the college handle such matters?" 

The black-clad young man gave Jing Yun a look with an idiotic expression. The academy's management was really ridiculous. 

"Jingyun, the conflict in Fengyun Canyon, does the sect care about it?" 

Lin Feng said something, and Jing Yun nodded slightly. Both the academy and the sect were established to help disciples become stronger. Some grudges and conflicts were the driving forces for their growth. In a world where the strong prey on the weak, who would bother with so many trivial matters? 

"Are you going to leave or not? Don't disturb my cultivation!" 

The young man in black said impatiently, a trace of disdain flashing in his eyes. These few people didn't even know the rules. They were clearly newcomers to the academy. 

"Lin Feng, he dares to wait for others to enter the cultivation tower in the tenth layer. His strength should be at least at the level of the third stage of the Spirit-Animal Realm. Let's go up." 

Yuan Shan said to Lin Feng, "Mengqing didn't come along with us. So Yuan Shan doesn't think that this group of ours has the strength to contend with them. Since we are inferior in strength, we should just go ahead and attack." 

However, Lin Feng's body remained there, motionless, with his eyes flickering. 

"Level Three of the Lingwu Realm!" 

Just so, his strength level is also at the level of the third stage of the Spirit and Might Realm. 

"Since there is a meditation room here, why not use it first? What are you going to do up there?" 

Lin Feng said indifferently, causing the gazes of several people to slightly narrow. Especially the young man in black, his eyes showed an amused expression. 

"Newcomers are just newcomers. They are naive and overconfident. They think that once they enter Tianyi College, they will be very powerful!" 

The man in black murmured to himself, a hint of anticipation showing in his eyes. It's not cheap to practice in the repair room of the tenth layer of this cultivation tower. It requires three inferior crystal stones a day. If one practices for a month, it will take nearly one hundred inferior crystal stones. This is no small amount of resources. One has to go to the Prison Arena and engage in a wild battle to obtain them. That desolate place, he wouldn't go there too many times anyway. 

"Lin Feng, don't be impulsive." 

Yuan Shan whispered, "They will be training in the cultivation tower for three months. Three months, two or three hundred inferior Yuan stones. This is a huge sum. I can't afford it now. I can only go to the cheaper training rooms upstairs. Moreover, they can't train for three months at once." 

"Nothing to worry about!" 

A hint of coldness flashed across Lin Feng's lips. Since the other party was going to openly seize the cultivation room, let's see if he has the strength to do so. 

With his feet lifted, Lin Feng walked beside the cultivation room and glanced at the dim and dull chisel-shaped groove on the crystal stone. 

"Is it okay to just insert the yuan stone into this?" 

Lin Feng turned to Yuan Shan and said something. 

Yuan Shan gave a slight nod and said, "Yes, every cultivation chamber is endowed with an array. As long as the primordial stone is placed in the groove, the array can be activated. With the least cost, it can trigger the primordial qi within the earth's energy source, making the primordial qi in the cultivation chamber extremely rich and suitable for cultivation." 

It was a very ingenious method. Lin Feng gave a slight nod and said to Yuan Shan, "If you practice for three months, how much Yuan Stone will be needed to maintain this magic circle?" 

"The cultivation chambers in the fourth to tenth levels of the Cultivation Tower all require three inferior Yuan stones per day." 

Three hundred pieces of inferior yuan stones. 

Lin Feng gave a bitter smile. It was true that cultivation required a lot of money. The Yuan Shi stones were already precious in themselves, and only those at the Ling Wu stage would use them. With so many Yuan Shi stones, they weren't something that could be easily obtained. 

Lin Feng inserted his hand into his bosom and then withdrew it. Immediately, a strong aura of primordial energy from the universe emanated from Lin Feng's palm, causing Yuan Shan's eyes to narrow slightly. 

"Medium-grade Yuan stone." 

Lin Feng has actually obtained a medium-grade Yuan Stone. 

"Three medium-grade Yuan stones, should there be no problem?" 

Lin Feng asked. 

"Surely, one medium-grade Yuan Stone is equivalent to one hundred inferior-grade ones. Moreover, it is purer and can activate the Yuan Qi Array to a greater extent." Yuan Shan nodded. 

While the young man in black on the other side had eyes gleaming with sharp intelligence, revealing a few strands of greedy expressions. 

This newcomer can even effortlessly produce a medium-grade primordial stone and take over his cultivation room. Isn't that a bit excessive?
