If heaven and earth are regarded as a living being, then the Great Tribulation is the outbreak of the diseases accumulated by the living beings for many years, and the immortal spirit refiners who have been eroded by the calamity are tumors that need to be removed or transformed.

Whoever can solve the cancer and disease for heaven and earth will be recognized and rewarded accordingly.

This is also the only chance in the great tribulation, grasp this opportunity, not only can you survive the great tribulation, but also grow rapidly in the process of the great tribulation.

For example, Yang Jian, the three Li brothers, and Lei Zhenzi and others in the original timeline, when they just finished learning the Tao and went down the mountain, they were probably in the stage of just becoming immortals, except for Yang Jian, the other disciples basically relied on the magic weapon given by the master to meet the enemy.

By the time the catastrophe was over, their strength had changed dramatically.

Or take Yang Jian as an example, when he first came out of the mountain, he had some difficulty dealing with the four generals of the Demon Family, and he needed to use his strengths and avoid weaknesses and use his wisdom to win.

But in the later stage, after the mana of the Twelve Golden Immortal Dao Exercises was cut off, he had grown into the first general under Jiang Ziya.

Whether it is against Zhang Kui or Yuan Hong, they can win the battle. At this time, his Immortal Dao realm had probably reached the peak of the Heavenly Immortal, and he was only one step away from the Golden Immortal.

At this time, Feng Yuan hadn't thought about it that much.

He was now performing the Qi Observation Technique, his eyes flashing with inspiration, observing the situation in Chentangguan in front of him.

Chentang Pass is an important pass that divides the two hundred princes in the north and north of the Great Shang Dynasty.

Later, the ghost side weakened, was defeated by the Great Shang Succession, and lost most of the land, and after these lands were divided, they became the princes of the two hundred roads in the north.

In Feng Yuan's eyes, in the void of this pass, there were layers of evil qi, and these evil qi even condensed into the shape of a bow and arrow, and the bow and arrow were facing the north, and it seemed to be pricked by a needle at a glance. Extremely sharp.

Within the pass, there are about tens of thousands of soldiers and horses.

"Wen Taishi conquered Beihai and took away the soldiers and horses of Chentangguan...... Now Chen Tangguan is at his weakest moment!"

Feng Yuan glanced at it and understood it in his heart.

Originally, there should be three or five hundred thousand elite soldiers and horses stationed in the border fortress like Chentangguan, but at this time, the north is fighting, and there are Jizhou Hou and Beibohou in front of it, and Chentangguan does not have to worry about the enemy from the north.

Wen Taishi's northern expedition passed through this place and transferred some of the soldiers and horses in the pass, which weakened the originally powerful and incomparable pass a lot.

This kind of sky-high evil qi is the use of formations by masters to fuse the evil qi of the army with the qi of the pass, and when defending the city, it can greatly increase the strength of the soldiers in the pass.

If it is an enemy, it will be suppressed by this evil spirit. Even if it is a true immortal, in the face of this kind of formation and evil qi, he does not dare to break through.

This is also the reason why in Feng Yuan's memory, Jin Zha and Mu Zha, who have become immortals, could not attack in the face of the Wandering Spirit Pass, and needed to disguise themselves to blend into the pass and gain the trust of the general soldiers in the pass.

"However, I'm not here to break through Chentang Pass......"

Feng Yuan turned into electric light, and instantly came to the gate of the pass, and then quietly operated the method of change of the dragon and snake three changes, and his body turned into a small green snake.

The green snake burrowed into the back basket of a trader, silently, and blended in without causing any fluctuations in the Great Array of Barriers.

......

In Chentang Pass, the street is bustling with merchants and people, very lively, although the north is fighting, but there are Jizhou Hou and Beibohou in the middle of the block, there is not even a little battlefield conquest in the pass.

In fact, the pass has not experienced a large-scale killing campaign for many years.

In a remote corner of the street, a green snake swam quickly, and in a slight flicker, it turned into a handsome boy dressed in brocade and looking about seven or eight years old.

Perhaps the appearance of the brocade boy is too outstanding, even if he stands in a remote place, he has attracted the attention of some people.

Feng Yuan patted his sleeve and moved his body slightly.

The three changes of the dragon and snake he learned can only change into the genus of the dragon and snake, and cannot change into others. So at this time, Feng Yuan had to restore the original body of the clone.

"If there is a chance in the future, you can not learn the Nine Transformations Xuangong, and it is best to start with the seventy-two changes of the physical body change supernatural power, otherwise, the clone may have to maintain this kind of childlike appearance for thousands of years!"

Feng Yuan secretly sighed in his heart.

Although his innate white tiger clone has deep heels and talents, it is also limited by his heels, and the human form transformed by the doppelganger is closely related to the growth of the white tiger body.

The body of the white tiger is in a juvenile body, and the human body incarnated by the Feng Yuan clone is the appearance of a handsome boy.

Only when the body of the white tiger reaches adulthood can the human body follow the adulthood.

However, the innate white tiger is an ancient divine beast, and it takes at least thousands of years to grow from a juvenile body to an adult.

During the growth period, there is no need for brute force to grow, and it has nothing to do with immortal cultivation.

If there is no way to change, Feng Yuan can only maintain this childish appearance.

Noticing the gazes of the people on the street, Feng Yuan's mind moved slightly, and his body disappeared out of thin air...... This is the obscuring method among the seventy-two methods of the earth's evil.

The large array of Chen Tang Pass is not inside the defense, although Feng Yuan's mana in the pass has been suppressed, but it can also cast magic powers, hiding from the ears and eyes of others.

There is a towering altar on the east side of Chentang Pass, and around the altar, there are a large number of armor guards.

Feng Yuan easily avoided the heavy guards and came to the altar.

The scope of the altar is not large, and there is a stone pavilion in the middle.

On the stone table inside, a quaint-looking war bow was placed horizontally, and there was a stone slab erected next to it, on which three protrusions protruded, and three iron arrows were stuck on it.

At the beginning, Emperor Xuanyuan's Qiankun bow and sky-shaking arrow looked similar to ordinary bows and arrows, slightly quaint, without the slightest decoration.

In Feng Yuan's eyes, this bow and three arrows are faintly swallowing evil qi, whether it is the Qiankun bow or the sky-shaking arrow, there is an incomparably fierce innate killing machine contained in it.

Any weapon that contains this kind of aura is a killing artifact.

In addition, this altar was connected to the evil qi of the void and the leylines of Chentang Pass, and the bows and arrows on it were blessed, and they were extremely heavy, and ordinary people could not pick them up at all.

This is also the reason why the general soldiers of Chentangguan only set up sentry posts around the altar and did not care about the protection on the altar.

Feng Yuan stepped forward directly and entered the stone pavilion.

With his right hand, he grabbed the Qiankun bow, and a cold and gloomy innate murderous aura instantly came from the bow.

The Innate White Tiger was born with the ability to master this murderous aura, so Feng Yuan's complexion did not change in the slightest.

"What a heavy bow!"

He urged the power of his body, and suddenly forced, and took the Qiankun bow in his hand.
