Among the holy realms, one out of a million people can break through the first level; one out of a hundred billion people can break through the second level may appear, and it will be recorded in history. Those who break through the third level are not recorded in history books.

The Divine Customs is to open up a spiritual world within the Yang God. This spiritual world will become the source of power of the Yang God and be called the Divine Sea.

However, it is extremely difficult to create a spiritual world out of nothing. What's more, this spiritual world must be strong enough to become the growth base of the Yang God.

However, this level is actually not difficult for Wu Dong. Spirit is a vague and ethereal thing. It is not matter, or even simply energy.

Wu Dong originally originated from the low-dimensional world. Before him, he was equivalent to a spirit, not a substance. Now, he wanted to open up another spiritual world, which was almost his innate instinct, and he could accomplish it in one thought.

The next second, a spiritual world appeared in his body. This spiritual world is currently very weak and is placed in a cell of Wu Dong.

Then, he took out hundreds of spiritual stones and began to absorb energy from them. With the help of the Yin-Yang Creation Array, he introduced the spiritual power into this new spiritual world.

These spiritual stones were his previous spoils, and the number was limited. Soon, more than a hundred spiritual stones were consumed, and the spiritual world was only slightly stronger.

"If you want it to biochemically produce a spiritual ocean inside, at least one billion spiritual stones will be used." He murmured.

Some spiritual stones like this are cheaper, and can buy hundreds of dollars with one dragon coin. Others are extremely high. This is because the price difference between the spiritual energy frequency in the spiritual stone, the higher the frequency and the lower the frequency, the price difference is one billion times. Because the higher the frequency, the stronger the energy.

For example, the best among the spiritual stones is that its frequency is ten thousand times that of the normal Yang Shen frequency, and nearly a hundred times higher than that of Wu Dong's Yang Shen frequency.

This kind of spiritual stone costs 30 million dragon coins per piece. But if it is about the same frequency, the price is much cheaper. For example, a spiritual stone with a frequency of 120 times, a piece of spiritual stone costs 1 million dragon coins per piece. The latter kind of spiritual stone is currently more suitable for him.

One billion spiritual stones like this are ten trillion Qinglong coins. Before, Liu Fu gave him a package with tens of trillions of Qinglong coins in it, which he could afford.

Before he knew it, it was already dawn. Concubine Ji Yu called him, and the two returned to the Shen Dynasty and came to the headquarters of the Spirit Array Master Guild in Shendu.

The Spirit Array Master Guild is an institution that is more influential than the Alchemist Guild, and its assessment is stricter. If it weren't for the Ji Yufei, Wu Dong wouldn't even be able to enter.

The spiritual formation masters shared resources. They came to a warehouse for selling the spiritual world. As soon as they entered it, Wu Dong was shocked. This was filled with various powerful spiritual worlds, and most of them he had never seen before!

Moreover, these spiritual worlds are extremely expensive. A medium-sized spiritual world costs up to hundreds of millions of Qinglong coins. Some of the high-end ones are even hundreds of billions of yuan, and some are even priced at trillions of yuan.

He couldn't help but sigh: "This spiritual formation master is really expensive."

Ji Yufei also agreed with this view, saying: "If I hadn't been supported by my father and brother, I would not have been able to become a spiritual formation master. This is why there are very few spiritual formation masters. If you want to become a spiritual formation master, you need not only talent but also money."

Wu Dong: "Does there be many students in Lingjie Academy?"

"It's very rare, the spiritual array masters in it are no more than one thousand. In comparison, there are as many as 100,000 warriors in Zhenwu Academy." Ji Yufei said, "But once the spiritual array master reaches a certain level, it is an invincible existence. His cultivation may not be high, but he has the ability to kill the golden immortal."

Wu Dong nodded: "It's true."

Immediately, Wu Dong instructed Ji Yufei to purchase five Five Elements Spirit Worlds at Level 6 and spent 300 billion Qinglong coins. Ji Yufei also struggled with such a large amount, and even borrowed 100 billion from Wu Dong to collect it.

He himself also selected five five elements spiritual worlds, all of which were high-end spiritual worlds.

There are standards in the spiritual world, from level one to level ten, each level is divided into three levels above, middle and lower. Above level ten, it is called king level and emperor level. This standard is similar to elixirs.

These five spiritual realms are the Sword Yuan Realm, the Qingmu Realm, the Ksitigarbha Realm, the Spirit Water Realm, and the Spirit Fire Realm. They are all spiritual realms above the ninth level, each of which costs 20 trillion in total!

This was purchased by him in the name of Ji Yufei, otherwise the price would be even more expensive! However, he didn't feel sorry for him. After all, these five spiritual worlds can be put into his five internal organs and further improved the Five Elements Spirit Array.

Before, he opened the shackles of the spiritual world and his body was able to be incorporated into the spiritual world. Now that he has come to the spiritual world warehouse, of course he has to buy some to see the effect.

After buying the spiritual formation, Wu Dong participated in the assessment of the spiritual formation master with the recommendation of Ji Yufei. The assessment process was to use the spiritual world to create the required spiritual formation.

Soon, Wu Dong made a first-level spiritual array, which fully met the requirements and became a one-star spiritual array master. There was no frequency restriction here, so he then took the two-star exam.

He was not in a hurry and was admitted to the Spiritual Array Master, but he was the stepping stone for joining the Spiritual Realm Academy in the future. It would be not too late to take the exam at the later level in the future.

After coming out of the Spirit Array Master Guild, Wu Dong came to Wanbaolou in Shendu. There are many chain stores like Wanbaolou, but he is used to buying at Wanbaolou because he is a member and has discounts.

This time, he bought 1.2 billion high-end spiritual stones and spent about 11 trillion yuan.
