The War Army Hall is built on a primordial vein. It has rich energy of heaven and earth, and it will absorb the free energy of heaven and earth. Therefore, the energy of heaven and earth is very sufficient.

In the Zhanjun Hall, one cultivation room after another was built. The cultivation room was divided into three levels according to the purity and richness of the heaven and earth's vitality.

Black iron, bronze, silver.

The black iron-level cultivation room has three times the richness of the world energy that is outside the world, and its purity is three times that of the outside world. By calculation, the difference between it and the outside world is nine times. One silver heart needs to be paid for a month.

The bronze-level cultivation room has four times the richness of the heaven and earth energy that is outside, and its purity is four times that of the outside world. The difference between it and the outside world is sixteen times. You need to pay five silver hearts a month.

The silver-level cultivation room has five times the richness of the world energy that is outside the world, and its purity is five times that of the outside world. The difference between it and the outside world can be considered twenty-five times. You need to pay ten silver hearts a month.

For many people, even a black iron-level cultivation room, one silver heart per month is very expensive, because it is only a nine-fold increase in the cultivation speed. It is only a short period of practice for a short period of one month, at best, it is equivalent to practicing in the outside world for nine months, and the improvement is not very obvious.

As for the five bronze-level and ten silver-level, the value is even higher.

Generally, people who choose to enter the War Military Hall and open to the outside world often have some wealth, just like that, and are on the verge of breakthrough, need to make breakthroughs in a short period of time to reach a higher level. For example, if you break through to the peak of the seventh level of the eternal heaven to the eighth level of the eternal heaven, pay a heart of silver, and enjoy nine times the energy of heaven and earth in the black iron-level cultivation room. There are ten things you can break through and quickly consolidate your cultivation.

It’s worth a lot, but it makes sense to think about it. After all, this training room is not simply a high degree of vitality, but also a level of purity.

For practitioners, the concentration and purity of vital energy are two indicators, which are very important.

The concentration multiple of a single unit gas is very high, but it also needs to be refined. If the refining speed cannot keep up, it will not be able to increase the cultivation speed much. Therefore, only if the purity also keeps up can the refining speed be faster and the overall cultivation efficiency will be higher.

"A silver-level practice room, one year." Chu Mu said.

When the deacon heard this, he was immediately overjoyed.

A year in the silver-level practice room is a hundred silver hearts. What a great fortune. He can draw one percent. That is a silver heart. For him, the seven-star holy level, the value of a silver heart is absolutely high.

"Please follow me, please." The deacon treated Chu Mu as a distinguished guest and had a respectful attitude.

"Let's wait." Lin Biruo suddenly opened his mouth and called out to the deacon.

Chu Mu didn't care about the price, but the little maid Lin Biruo felt distressed and bargained with the other party.

According to the little maid Lin Biruo, eight silver hearts were a month old, and the deacon insisted on the price and refused to give in. Chu Mu looked at it with a funny look.

In the end, the deacon took a step back and provided a free black iron level training room for a year.

Lin Biruo was not satisfied with this result, and she wanted to cut the price.

"Okay, let's do it." Chu Mu grabbed Lin Biruo and said, "Birou, you can use that black iron level training room."

"Young Master, this..." Biruo was anxious.

"Practice with peace of mind and try your best to improve your cultivation." Chu Mu said.

The deacon opened the energy of two cultivation rooms in advance, took Lin Biruo to a black iron-level cultivation room, and then took Chu Mu to a silver-level cultivation room.

Chu Mu walked into the silver-level cultivation room and immediately felt the rich and pure energy of heaven and earth fluctuations.

Close the silver-white door, and the walls around it are also silver-white. They are crushed with silver stone and ground into powder, and then applied with other materials, making the walls stronger and some barriers to strengthen defense are arranged. Therefore, even the attacks of the Nine-Star Holy Level cannot be destroyed.

Chu Mu felt it carefully.

Five times the richness of the heaven and earth's vital energy, and five times the pureness of the heaven and earth's vital energy.

In this way, Chu Mu was almost unable to take it into account and was wrapped in the energy of heaven and earth.

Under the absorption of the Dragon-Swallowing Jade Pendant, the surrounding heaven and earth vital energy quickly gathered, flowing through the inside of the Dragon-Swallowing Jade Pendant, slowly transforming, and then entering Chu Mu's body and transforming into the Divine Wilderness Sword Yuan.

However, Chu Mu discovered that the gathering of heaven and earth vital energy and the dragon-swalking jade pendant could only absorb part of it, less than half of it.

There is a cushion in the middle of the training room, which can make people calm and concentrate faster and eliminate distracting thoughts.

After Chu Mu sat on it, he tried to take the initiative to move the Shenhuang Sword Yuan to practice and see how the cooperation with the Dragon-Swallowing Jade Pendant was achieved.

A large amount of heaven and earth vital energy began to pour into Chu Mu's body and was refined by him.

The active cultivation and the swallowing and spitting of the Dragon-Swallowing Jade Pendant can indeed be superimposed on each other.

"Okay, I'll stay here this year to practice the Divine Sword Yuan." Chu Mu's eyes opened, revealing a hint of joy.

According to the current cultivation speed, one year of cultivation will be equivalent to more than ten years of cultivation in the outside world. Perhaps your cultivation level can be further improved from the current early stage of the fifth level of the eternal heaven to the early stage of the sixth level of the eternal heaven.

In the early stage of the Sixth Eternal Heaven, his strength can definitely reach the level of the Nine-Star Saint Level. As for the initial level of the Nine-Star Saint Level or the intermediate level of the Nine-Star Saint Level, Chu Mu cannot confirm yet, because the high-level Saint Level is a level that he has not yet reached.

"I don't know if it's faster if you take the Speed ​​Spirit Yuan Pill?" A thought came out of Chu Mu's mind.

The Speed ​​Spirit Yuan Pill is said to be able to assist in the cultivation speed of ten times faster after taking it, and because of its value, it is higher than the Dragon Swallowing Jade Pendant.

Ten times, maybe it's true, but now Chu Mu has the Dragon-Swallowing Jade Pendant. If the two are superimposed on each other, I don't know if they can be completely superimposed, but I still have to give a discount.

After a change of thought, Chu Mu decided to try it, take out the white jade gourd, open it, and pour out a quick spirit pill.

The Suling Yuan Pill is milky white all over and emits a very faint fragrance. It is an almost flawless elixir. From the appearance of the elixir, it can be seen that the person who refined this elixir must have a very profound attainment in alchemy. After all, Chu Mu himself is also a great master of alchemy, but he has not dabbled in elixirs for a long time because he does not have the time and energy.

Throw the Suling Yuan Pill into your mouth, melted quickly into a clear stream, and swallowed it into your stomach.

Suddenly, the clear stream turned into a stream of energy, and quickly spread out, like the breeze and drizzle moistening things silently, spreading every part of Chu Mu's limbs and bones.

My whole body began to become lighter, as if I was gradually losing weight and ascending to the sky.

But Chu Mu knew that his weight had not changed at all, but the power of the Suling Yuan Pill spreads under his body, causing a special change in his body. Under this change, every part of his body had extraordinary sensing and absorption ability to the heaven and earth's vitality.

"So, this is the so-called ten times the cultivation speed." Chu Mu said intimately.

After a change of thought, combined with his own attainments in the alchemy, Chu Mu came to a conclusion that the so-called ten times of cultivation speed is relative, with an absorption speed of ten times, and his own refining speed must keep up to reach a ten times of cultivation speed.

Chu Mu's dantian is different from that of ordinary practitioners, and it is ten times larger. The holy body in the middle stage of level 5 is very powerful. His meridians have also undergone changes and become wider and tougher. Moreover, the Shenhuang Sword Yuan is a very clever sword Yuan. Under various combinations, his speed of refining the vital energy of heaven and earth is much faster than his speed of absorbing the vital energy of heaven and earth.

"Start the in-depth practice."

Eliminating all distracting thoughts, the Shenhuang Sword Yuan started to activate. Suddenly, a suction force emerged, and the surrounding heaven and earth vital energy were absorbed and gathered, wrapping around Chu Mu's body, forming a trace of white, like fog, gradually wrapping Chu Mu's whole body.

The whirring sound gradually sounded in the practice room, as if gusts of wind were blowing continuously, becoming clearer and clearer.

The body that became extremely sensitive had a sense of beyond imagination to the heaven and earth's vitality. With the thoughts moving, countless invisible palms seemed to extend out of the body, stirring around madly, constantly absorbing the heaven and earth's vitality.

The vitality of heaven and earth seemed to be rushing wildly, making a howling sound.

The pure and rich energy of heaven and earth gathered in a rush with the help of the Speed ​​Spirit Yuan Pill, swarming Chu Mu's whole body, as if trying to squeeze Chu Mu.

The pores on the whole body were wide open, and the rushing heaven and earth energy continued to absorb into the body. The Shenhuang Sword Yuan gradually burst out at an astonishing high speed and rushed into the strong and wide meridians.

Chu Mu rarely had such an opportunity except for fighting.

Generally, when practicing, the external world's vital energy is rich in ordinary degrees, and the speed of his own absorption of vital energy is also normal. Only the refining speed is extraordinary. However, under most opportunities, the extraordinary refining speed can only be the same as the absorption speed because the absorption speed cannot keep up.

As the Shenhuang Sword Yuan was running faster and faster, Chu Mu vaguely heard roars, sounding from his body, it was like a roar running like a river, or a roar impacted by waves.

The feeling of powerful power ripples in the body.

As the Shenhuang Sword Yuan continued to operate, the heaven and earth vital energy absorbed into the body was also driven, rushing rapidly into the strong and wide meridians, and was refined bit by bit. The Dragon-Swallowing Jade Pendant also absorbed part of the heaven and earth vital energy and then transported to Chu Mu's meridians.

The Divine Sword Yuan grows rapidly at a speed that can be felt. If you continue to practice at this speed, you will definitely reach the sixth level of the eternal world after one year. r1152
