Generally speaking, the lowest-level Yellow-level low-level martial arts only need one meridian to transport the aura in the dantian into the weapon, and the same is true for the yellow-level mid-level.

However, the high-level martial arts of the yellow level need to be transported by two meridians at the same time to meet the requirements required by the Red Moon Slash.

As we said before, if the meridians are like a river and the aura is water, then there is a limit to the amount of water that can pass through this river.

If you want to exert the power of the Akatsuki Slash, you have to infuse the aura in the dantian into the weapon on your right hand through the two meridians at the same time.

If you can't synchronize it, the aura in the weapon can't meet the requirements, and you won't be able to fully exert the power of the Akatsuki Slash.

After all, if the aura can't be filled with weapons in a short period of time, it will then dissipate from the weapons and dissipate between heaven and earth. If we want to use the maximum power of our martial arts, we have to slash the weapon in our hand into the enemy's body at the moment when the aura fills the weapon.

Of course, the aura does not disappear immediately after entering the weapon, and it takes a process in between. This is also the reason why Li Xing did not hit Zhang Tianzong before, but made a crack in the ground.

The reason why martial arts requires the spiritual energy in the dantian to be filled with weapons from the hands through the meridians in a short period of time is mainly because the speed at which the spiritual energy dissipates is far greater than the speed at which the body replenishes. If you can't fill it up as soon as possible, the power of your martial arts will become weaker and weaker.

Previously, he cultivated yellow-level low-level or even yellow-level middle-level martial arts, because he only needed to control one meridian, and Zhang Tianzong could bring out the maximum power of the martial arts in just one day.

But now, with two minds, it is necessary to control the aura transportation speed of the two meridians at the same time, and the difficulty of this is really not ordinarily low.

Your sister's failed again, Zhang Tianzong couldn't help but curse in his heart.

And according to my father, a heaven-level high-level martial art requires controlling the six meridians on the right or left hand at the same time, and I don't know how these guys do it.

After sighing for a while, Zhang Tian looked at the direction of the sun, it was about ten o'clock in the morning.

After replenishing the aura of his body to about two-thirds, Zhang Tianzong stopped cultivating and got up and rushed to the county seat.

Fenglin County covers an area of about three miles long and three miles wide, and is the largest county seat around Zhaojia Village.

As usual, Zhang Tianzong's target this time is still the south of the city. There was a small trading center covering an area of dozens of acres, and there were cultivators who specialized in selling all kinds of items there.

The so-called trading center is where cultivators sell the demon beast inner pill they have caught in the wild, the spirit grass they have collected, or various refining materials, and they can also use the items they have to directly trade with other cultivators what they need.

And most cultivators don't understand the price of Neidan or various spirit grasses and refining materials, so there are vendors, who buy items from cultivators at a low price, and then sell them at a high price to large trading houses such as Guiyi Pavilion and Feiyu Pavilion, or they can sell them to other cultivators at a high price to earn the difference.

As for why large commercial houses such as Guiyi Pavilion and Feiyu Pavilion didn't send people to the trading center to buy the spirit grass materials they needed, in addition to the trouble, the most important reason was that they couldn't afford this profit.

Of course, cultivators can also directly sell the Demon Beast Inner Pill or Spirit Grass they have obtained directly to the Guiyi Pavilion, but if there is a small amount, the price of the same item is lower than that of the trading center, and it is not possible to barter for things.

Zhang Tianzong's previous identity was that he was a small trader, buying spirit grass materials from cultivators or other traders at a low price from the trading center, and then selling them to a good shopkeeper of the Guiyi Pavilion.

"Tianzhong, I haven't seen you for a few days, what are you gaining this time?"

"Tianzong, look at the spirit grass I have here, do you need it?"

"Boy, I finally saw you again, Uncle Zhang left you some good things, come and take a look?"

“......”

As soon as he entered the market, the vendors who knew him on the left and right greeted him one after another, and it was conceivable that Zhang Tianzong's popularity here was not low.

As for why they don't call Zhang Tianzong 'waste', the main reason is that eleven years have passed, except for a few villages around Zhaojia Village, who knows what background Zhang Tianzong has, not to mention that there are so many people with the same name and surname in the world.

Of course, if someone deliberately reminds them, most people will immediately know the ins and outs, and you must know that when Zhang Tianzong was born, this matter was in an uproar.

It's just that even if he knows that Zhang Tianzong is a 'waste', the trader probably won't call him in person, after all, businessmen pay attention to harmony and make money.

"Uncle Liu, I told you before, no spirit grass can hurt the roots or branches and leaves, otherwise the price will be greatly discounted. ”

"It's not black lazuli, Uncle Zhang, it's just that the outer layer is wrapped in a layer of black lazuli, and the inside is full of stones, and you have been pitted. ”

"Uncle Li, you're either a spirit grass or an ordinary weed. ”

“......”

There is also a connection between the vendors and the vendors, and many times they will gather the things they buy together and sell them to Guiyi Pavilion or Feiyu Pavilion, as long as the quantity reaches a certain level, the purchase price there will be higher.

Because Zhang Tianzong treats people sincerely and does not mind teaching what he has learned to his peers, he has a good reputation in the trading center.

And the vendors are not all shrewd merchants, they also have times when they look away, and the black gold stone just now is an example.

If it is a black lazuli of the same volume, the weight will be lighter. As for the function of black lazuli, it is used as fuel for alchemy.

The fuel required for the first to ninth level elixirs in the Tianxiao Continent was different, because some of the fuel temperature was not enough, and they couldn't even refine the spirit grass, let alone purify it.

Zhang Tianzong is now a second-grade alchemist, and the fuel required for alchemy is the second-grade fuel black lazuli and the first-grade fuel charcoal, which are mixed in a certain proportion to reach the temperature required for the refining of the second-grade pill or the condensation.

In the same way, the third-level elixir also has a third-level fuel entanglement stone, and the fourth-level has Qingtao stone, and each level of elixir has a corresponding fuel, and the temperature cannot meet the requirements at all if you use low-grade fuel.

Of course, alchemy or refiner, fuel and danding are only the foundation, and the most important thing is the material of alchemy or refiner.

Take alchemy as an example, the first-level elixir only needs three to four first-level spirit grasses, but the second-level requires six to eight kinds of spirit grasses first-level and second-level spirit grasses, and the ninth-level supreme creation pill requires nine hundred and ninety-nine kinds of heaven and earth treasures, including the essence blood of thirteenth-order demon beasts, first-level to ninth-level spirit grass, and other things.

To put it simply, there are hundreds of thousands of spiritual grasses and various refining materials in the Tianxiao Continent, and if you want to accurately distinguish them, and then clearly know the price, the difficulty of this can be imagined!
