The immortals of the two worlds started from farming and refining pills.

The Tai Chi scroll, the natal spiritual weapon that incorporates the visualization diagram, naturally has a strong restraint on the inner demons.

Soon, as the black and white halo on the Tai Chi scroll circulated, the calamity clouds in the sky suddenly shrank, and then rolled up again.

Taoist Cheng Qing's expression changed slightly: "The nine calamities have passed, but the calamity clouds have not yet dispersed. This means there are at least twelve levels of calamity."

Taoist Zeng Lu frowned and said, "Twelve-fold thunder tribulation, I wonder if Taoist Niu is well prepared."

Li Qing looked at Sang Yuwan and said, "Brother Daoist survived the eighteenth thunder tribulation that day, so I think it should be no problem for Brother Daoist Niu to survive the twelfth thunder tribulation."

When these words came out, Cheng Qing and Zhao Yao from Tianyun Mountain did not show any surprise. They were also in the Great Zhou Dynasty, and they were also familiar with the deeds of Master Sang from Yanglong Lake.

On the other hand, Taoist Zeng Lu and the other four people who were building foundations abroad showed moved expressions on their faces: "The Immortal is really powerful! He can even survive eighteen calamities!"

Sang Yuwan stroked his beard and smiled: "It's just a bit of luck, it's just a blessing from heaven."

The younger generations of the Niu family were a little worried at first, but they were somewhat comforted.

At this moment, the calamity clouds in the sky suddenly turned into an interweaving of five colors: white, blue, black, red, and yellow, giving rise to terrifying lightning.

The Ding Fire Divine Thunder and the Ji Earth Divine Thunder, which had appeared in the previous calamity clouds, were also among them.

Li Qing couldn't help but be surprised: "The Five Thunders of the Later Heaven! How could it be so dangerous?"

The five elements of thunder are divided into five innate thunders and five acquired thunders.

Among them, the five acquired thunders are Yi wood divine thunder, Ding fire divine thunder, Ji earth divine thunder, Xin metal divine thunder, and Gui water divine thunder.

Most of the time, they exist alone, but there are also times when the five elements combine into one.

There is a powerful thunder method known as the "Five Thunders Method", which is formed by accumulating and refining the five acquired thunders. It is magnificent and unrivaled.

But as a five-element thunder tribulation, it appeared during the pill-forming tribulation, which was unheard of by everyone present.

Li Qing calmly communicated with Sang Yuwan: "Brother Daoist, your thunder tribulation was so strong that day because you went against the will of heaven and wanted to help those old dragons regain their vitality."

"In addition, the opportunity inheritance of Yuanying Zhenjun led to the entanglement of cause and effect, which triggered the changes in the will of heaven, and this is why there are eighteen levels of thunder tribulation."

“But I see that Fellow Daoist Niu has a very simple cause and effect, so how could he have such an experience? The first ten levels of thunder tribulation were even more powerful than the one you experienced that day.”

Sang Yuwan replied through voice transmission: "Perhaps it is because the Yin-Yang Dao is so profound and involves the origin of heaven and earth that this disaster occurred."

Most of the spiritual practices in Qinghe Continent are based on the Five Elements. Even if one has unusual spiritual roots such as thunder, wind, and ice, they are still similar to the Five Elements practices.

But the way of Yin and Yang is different. Not only is it difficult to get started, but it is even more difficult to delve into it.

Most cultivators only know one or two spells based on yin and yang, and occasionally some people know some magical powers.

But if one really wants to take this path to build the foundation, or even to form the elixir, at least in the countries near the Great Zhou, there has never been such a person.

Li Qing couldn't help but sigh: "The key to this is really profound. We can only wait and see what happens."

Fortunately, when entering Xinglin that day, Li Qing used the "Gate of Tianwei" to observe and found that Niu Xinjing was favored by good fortune, so it seemed that no accidents would happen.

While the two were communicating with each other, the five-colored thunderbolt from the sky had already fallen.

"Boom!" The thunder was violent and deafening.

Li Qing only felt a flash of light and then a dark flash before his eyes, and the thunder tribulation had already descended upon the top of Niu Xin's lens.

Niu Xin Jing was not at all confused. He raised his hand and pointed. The Tai Chi scroll swelled up in the wind and turned into a giant curtain covering the sky, enveloping the thunderbolt.

"Crackle..." After a burst of thunder, the five elements thunder tribulation disappeared.

Sang Yuwan used the Spirit Eyes spell to observe the Tai Chi scroll for a long time before exclaiming in amazement: "I underestimated Daoist Fellow Niu! How can this be some kind of natal spiritual weapon? It's clearly a magic weapon."

Magical weapons are treasures used by Jindan Zhenren, and they belong to the third level. For Jindan Tribulation, it is simply a dimensionality reduction attack. If it is someone else's magic weapon, even if it is ownerless, it is difficult for a foundation-building cultivator to drive it, let alone use it to overcome the tribulation.

It just so happened that this Tai Chi scroll was the evolution of Niu Xinjing's original spiritual weapon. Even though it couldn't be said to be as smooth as using one's own arm when using it now, it was very smooth.

And the calamity clouds in the sky changed again.

Li Qing heaved a sigh of relief: "Fortunately, although this thunder is strong, there is only one, so it won't make people lose their composure."

Taoist Zhao Yao, who was standing next to him, turned pale. “This one move alone can kill many ninth-level foundation-building cultivators.”

His cultivation level is now at the eighth level of foundation building, and he is not far from the ninth level, or even from overcoming the tribulation of forming a pill.

He originally had a high opinion of himself and had long been planning for the opportunity to form an elixir. But now, seeing Niu Xinjing's situation, he felt inexplicably discouraged.

Li Qing glanced at him and understood in his heart: In the Great Zhou Kingdom, there might be another cultivator who stopped at the foundation-building stage.

Watching the ceremony to overcome the tribulation is a double-edged sword.

The strong can gain more knowledge and experience, and will have more confidence in overcoming future tribulations.

The weak may be hit and never recover, but if they don't go through the calamity, they won't fall into it. It's hard to say it's not a blessing in disguise.

Li Qing would not look down on him for this, but he would definitely not act like that.

Compared with the terrifying thunder tribulation of the Five Thunders of the Later Heaven, Niu Xinjing's eleventh thunder tribulation is relatively much simpler.

It is the Bing Fire Divine Thunder that Sang Yuwan once passed through, and is ranked among the five innate thunders.

In this regard alone, the mysterious power of the five innate thunders is certainly superior to the five acquired thunders, but it is far from being comparable to the combined power of the five acquired thunders.

Li Qing watched as the Ox Heart Mirror used the Tai Chi scroll to dissipate three consecutive Bing Fire Divine Thunders, and his heart gradually lifted.

His spiritual sense was touched, and he had a premonition that the time when Niu Xinjing formed the elixir should be the twelfth heavenly tribulation.

In this way, the tribulation has reached the final stage!
Suddenly, streaks of purple air emerged from the calamity clouds in the sky, making people tremble with fear.

"Divine Heavenly Thunder!" A foreign foundation-building cultivator exclaimed in surprise.

Li Qing and Sang Yuwan breathed a sigh of relief at the same time.

On that day, Sang Yuwan's last thunder tribulation was a lower-level thunder of the Purple Sky Divine Thunder, the Divine Sky Thunder.

Many old dragons offered their lives to replace each other, but still could not survive.

Sang Yuwan finally succeeded in overcoming the tribulation, thanks to the magic weapon transformed from the red dragon coral.

Now, Niu Xinjing has refined a magic weapon without anyone noticing, so it should not be a problem for him to overcome the tribulation.

However, at this moment, something changed.

Outside Xinghua Village, a mysterious figure rose into the sky and threw a scarlet gem into the calamity cloud.

"Oh no! Someone is interfering!" Sang Yuwan and Li Qing stood up suddenly and wanted to intercept them.

However, the scarlet orb was unstoppable and was willing to destroy itself in order to break free from the two people's entanglement.

Li Qing and Sang Yuwan were worried about getting involved in the thunder calamity, which caused unexpected changes, so they were a little slow and could only watch the precious orb blast into the calamity cloud.

"Rumble..."

The already powerful Divine Thunder became even more powerful. (End of this chapter)
