The method of breaking the Tiangang Seven Star Array is not the only one, and the method of breaking the formation adopted by Lu Chen is the method of generating numbers of the five elements.

Before stepping into the battle, he had already prepared the relevant five elements, such as torches, nameplates of British soldiers, earth and stones, drinking water, and firewood.

"Yi Ji Ci Biography": "Heaven one and earth two, heaven three and earth four, heaven five and earth six, heaven seven and earth eight, heaven nine and earth ten." ”

Heaven, after being abstracted, represents yang, represents the odd number of numbers, is one, three, five, seven, nine, and is called one day, three days, five days, seven days, and nine days.

On the contrary, after abstraction, it becomes yin, representing the even numbers in the numbers, which are two, four, six, eight, and ten, and are called earth two, earth four, earth six, earth eight, and earth ten.

In this way, the number of days is five, and the number of places is five, which is in line with the "principle of the five elements, the original nature, the generation of heaven and earth, and there are no numbers".

The number of these five elements is the root of everything, whether it is the thirty-six Tiangang, or the Big Dipper, or other changes, they are all in the changes of the five elements.

It can be said that the number of these five elements is like the outline of a novel, and the change of the formation is the plot.

After Lu Chen stepped into the formation, there were words in his mouth: "Heaven is born of water, and the earth is sixty percent of it; the earth is two of the fire, and the sky is seven percent of it; the sky is three of the wood, and the earth is eighty percent of the earth; the earth is four of the gold, and the sky is ninety percent of the earth; the five of the heavens are the earth, and the earth is ten percent of the earth." ”

"Tianyi" is "Shuijia", "Earth 2" is "Huoyi", "Tiansan" is "Mubing", "Earth Four" is "Jinding", "Tianwu" is "Tuwu", "Earth Six" is "Shuiji", "Tianqi" is "Huogeng", "Earth Eight" is "Muxin", "Tianjiu" is "Jinren", and "Earth Ten" is "Tuqi......

This is the number of heaven and earth, yang and yin, that is, the so-called 'river map'.

According to the Five Elements Generation Number Solution of the River Map, Lu Chen walked and stopped in the formation, and every time he stopped, he would put down a kind of Five Elements thing in his hand.

After putting all the things of the five elements away, a smile finally appeared on his face that had been tense.

"Miss Yan, when I move forward later, you can help me pay attention to the five things behind me, they represent gold, wood, water, fire, and earth. Please tell me which of them has changed as I travel. ”

Lu Chen turned around and explained to Yan Meng in a loud voice.

"I understand, Brother Lu. ”

Yan Meng was smart, and when he heard it, he understood what Lu Chen meant.

Lu Chen nodded, and then began to continue walking forward, and when he walked to the position of the Shaking Star in the Seven Stars Array, the nameplate of the British soldier he placed in the formation suddenly shook.

Yan Mengzheng was engrossed in observing the five things, and after noticing the change in the nameplate, he hurriedly shouted, "Brother Lu, that nameplate has moved." ”

Hearing this, Lu Chen gave her a thumbs up, and then took four steps to the west.

The earth is four gold, and the west is the main gold.

After taking these four steps to the west, he continued to move forward, and when he reached the position of Kaiyang, the lit torch jumped again.

"Brother Lu, fire!"

Under Yan Meng's reminder, he took two more steps south.

The second fire is made in the ground, and the main fire is in the south.

......

With every time Yan Meng spoke, Lu Chen had to change his direction accordingly, but in half an hour, he had already walked thousands of steps.

For him, this thousand steps is nothing at all, but when traveling, he also needs to consider the direction and number of steps, and distract from it. It may have been difficult at first, but the later he went, the longer he needed to calculate and think about it, the longer he needed to think about it, forcing him to take longer to think.

By the time he reached the area of the last six stone pillars, Lu Chen was already sweating profusely.

"Brother Lu, you're about to succeed, come on!"

Yan Meng saw Lu Chen getting closer and closer to the altar, and the more joy on his face, he couldn't stop cheering for Lu Chen.

"Water...... Is it Tianshui Beiyi or Dishui Beiliu? Is it one step or six steps?"

The more Lu Chen thought about the calculations, the more hesitant he became, the changes in the Tiangang Seven Star Array were complicated, and the extrapolation to the back really made his head as big as a fight.

"Forget it, the last step is directly reckless!"

He took a deep breath and decided to take a gamble, not wanting to spend a lot of energy trying to calculate the position as he had just done, so he took six steps straight north.

When the last step fell, Lu Chen carefully observed the surrounding environment, and after seeing that there was nothing abnormal, he finally breathed a sigh of relief.

After stepping over the last pillar, he had reached the altar.

This altar is about three feet high, and it is made of granite piles, which is similar to the one above the cave, and has a bit of a Mayan pyramid flavor.

Lu Chen glanced at the inscriptions and patterns around the altar cursoryly, and after seeing that there was nothing special, he went straight down the stone steps and climbed the altar step by step.

"It's ......"

When he walked to the top of the altar and saw what was placed on it, he was not slightly stunned, and a look of surprise flashed in his eyes.

At the top of this altar, there is actually only a jade bowl, but in this jade bowl, it is full of light red liquid, crystal clear, like red jade.

But what really surprised him was that at the bottom of this pale red liquid, there was actually a small snake as long and thick as chopsticks, with closed snake pupils, and its appearance was exactly the same as the mutated black snake he had encountered before, except that the snake's head was slightly raised, as if it had horns.

As Lu Chen approached, the little snake seemed to have sensed something and began to shake the snake's body, but his eyes were still tightly closed and he didn't open them.

The small snake's swaying body made the color of the crystal-clear pale red liquid become more and more intense, and finally it was almost as red as blood.

"This should be the earth dragon marrow, right? But such a big bowl of earth dragon marrow is used to raise a snake?"

Lu Chen muttered in disbelief.

It's not that he hasn't seen the market, it's because the scene in front of him is too outrageous, this earth dragon marrow is the essence of the dragon vein, which can be met but not sought, even if it is a drop, it is very rare and precious.

But the tribe that worships the giant snake actually uses a large bowl of earth dragon marrow to raise snakes, which is simply a luxury.

Thinking of this, he couldn't help but sigh and felt sorry for the Yan family brothers and sisters.

This earth dragon marrow is a strange thing in heaven and earth, and it must be held with jade in order to maintain the magical effect of the earth dragon marrow.

And the current earth dragon marrow, although it has been held in a jade bowl, there is still a small snake in this bowl.

According to the British soldiers who died in the battle, this little snake has lived for at least a century, and has long absorbed the earth dragon marrow, so even if so many earth dragon marrow are found, the effect will not be one in ten.
