It's actually a forced buy and a strong sell.

Chen Nan also doesn't understand the logic of systematic thinking, sometimes he can lend you points generously, and sometimes he is as good at calculating as a profiteer.

"Lord System, I think that Seven-Star Dragon Yuan is a bit expensive, can we change it."

After several rounds of wits and courage with the life-continuation system, Chen Nan has already figured out the routine, and at this time, he must not be tough, so he can only discuss it with a calm mind.

In fact, Chen Nan wanted to exchange for a few more Ten Perfect Tonic Pills, after all, he could face the demon clan at any time now, and it would be more secure to have one more item to instantly increase his level, although using this prop would have the sequelae of soft feet.

"The Seven-Star Dragon Yuan is specially customized for you, and the day after tomorrow you will be impacting the advanced evolutionary, we must plan for it now." The system slowly explained, and almost projected the words "I'm all for your good" into Chen Nan's sea of knowledge.

This familiar recipe and familiar sentence pattern are actually a little similar to the parents of Huaxia.

"I now have Chunjun and Chixiao, the two famous weapons have made me understand the sword, and I still have the confidence to impact the advanced evolutionary," Chen Nan said confidently, "Why don't we change to a cheaper one?" I'd like to exchange a few more Ten Perfection Pills. ”

"It's still too far away, you haven't touched the threshold of kendo at all." The system hit Chen Nan mercilessly, "Compared to that Hitomi Akiyama, you still have a long way to go on the kendo journey. ”

"But can I really master the kendo? I don't really understand the reason, why I have to spend tens of thousands of points to redeem a mold every time. Chen Nan voiced his doubts.

This really bothered him a little, because even if it was a famous artifact, it would cost tens of thousands of points, and if it was converted into runes from one to one, it would be tens of thousands of runes, which was the number of A-level mystical runes, and Chen Nan couldn't use it at all now.

While the inverted die can be used once on an improvised basis as a hole card to give your opponent a stunner, it may be of greater help if you spend those points elsewhere.

"You've been an evolutionary for three days, why do you still ask this kind of rookie question?" The system wondered.

Is three days a long time?

Chen Nan wants to cry without tears, other people's evolutionary roads will take decades, but he himself is based on the sky.

Since being bound to the system, my whole life has pressed the fast-forward button.

Evolution not only did not prolong one's life, but it was precarious, and if one day did not collect the fragments, the life would be directly lost.

"Forget it, I'll talk to you about science." The system incarnated as an enthusiastic teacher and taught Chen Nan another lesson.

According to the three-pole theory, there are two great watersheds in the hierarchy of evolutionaries, which are 7 and 13.

Level 7 is based on the star core as the breakthrough point, and once you become level 7, you can start to use the star core to cultivate the mysteries and truly feel the charm of the elements.

And level 13, as the second watershed, is to know the sea as a breakthrough point. The level 12 sea of consciousness has reached a saturated state, like a thousand jun hanging above the star core, hindering the further improvement of the star core.

At this time, it is necessary to draw powerful energy from the star core, go retrograde along the body, break through the suppression of the sea of knowledge, and let the forbidden power of the sea of knowledge overflow outside the body, and no longer become an obstacle to evolution, in order to enter the sequence of advanced evolutionaries.

This powerful energy is called "Tao", and it is not a simple mystery, but an elemental operation rule mixed with the forbidden power of the gods.

Once an evolutionary focuses on the same type of mysteries and constantly intervenes with the forbidden power of the gods, they will have the opportunity to upgrade to the "Dao" and prepare for the impact on the advanced evolutionary.

Ryotaro Asaobuki has already touched this threshold, and his mystery "no bones in the world" is trying to enter the Tao, but it is still in a relatively early stage.

Theoretically, each of these mysteries can be used to enter the Dao, but most evolutionaries will choose to use the instrument to enter the Dao, because the runes of the instrument are dense, and they can condense more energy when they impact the sea of consciousness in the body.

However, there are also a few evolutionaries who choose to use the elemental mystery to enter the path to attack the sea of consciousness, and most of these people fail.

There are various names for the Tao, and each evolutionary can name it according to the instrument meaning of his or her choice, such as "Kendo", "Hanbana", "Kotodo", and so on.

According to the official statistics of the alliance, the most common breakthrough method among the world's advanced evolutionaries is to use a sword.

Because regardless of the East and the West, weapons in the form of swords are very common, and they seem to be more expensive.

Many evolutionaries who don't have a deep understanding of the moves will choose to use the sword to enter the Dao, and go up to level 13 recklessly, and if they don't succeed, they will become benevolent.

"I've actually been preparing for you to break through level 13 since day one, as the most powerful system host in the universe, you have to lay a good foundation when you hit level 13, otherwise your body will be difficult to continue to withstand the rapid improvement of the advanced realm."

The system was a little proud when it came to this, "Only famous weapons will make your sword intent fast in a few days, Chunjun and Chixiao let you have the experience of using famous weapons, and then the Seven Star Dragon Yuan will let you enter the house in terms of swordsmanship." ”

"I guess I understand, but can I choose a slightly cheaper sword?" Chen Nan still didn't give up his original idea, there are many famous weapons in the system mall, the cheapest one is only 20,000 runes, and the remaining points are exchanged for big tonic pills, isn't it fragrant?

"Rotten wood can't be carved," the system sighed pretending to be old-fashioned, "Do you know what the Seven Star Dragon Yuan represents?" Forget it, you definitely don't know. ”

The system thought about it and explained, "Chunjun contains the heaviness of the earth, Chixiao contains the restlessness of the flames, and the Seven Star Dragon Yuan contains the lightness of the wind, the wind can carry the upper and lower levels and yin and yang, and it is the most suitable weapon for you today."

Tomorrow, we will exchange for a famous weapon that contains the meaning of water, and you can use the sword as a medium to contact the four origins of earth, water, fire, and wind, and then combine them into the strongest sword formation, and hit level 13 in one go. ”

"Understood, I didn't expect that these swords could be combined into a sword array."

After some popular science, Chen Nan finally understood the good intentions of the system adults.

It seems that it is still safe to let the system recommend the exchange list, which is equivalent to a full-level grandfather taking you to upgrade and fight monsters, and every step has been planned.

It's just that some parts of this old man are not very easy to use, and he has to give him some engine oil every day, change parts or something.

"By the way, system, do I have a name for this sword formation?"

Chen Nan suddenly thought that since these four swords were all named after the famous swords of Huaxia, the names of the sword formations formed should be very popular, otherwise wouldn't it be detrimental to the prestige.

"Of course." The system triumphantly said.

What will it be called?

Zhuxian Sword Formation? Tiangang Beidou Sword Formation? All the gods are in a great array?

Chen Nan's heart flashed with all kinds of names, and he asked with anticipation: "Don't sell the system, what is the sword formation called?" ”

"Square Sword Formation."
