After the practice of the Yin and Yang Twin Evil Array was on the right track, Shi Dong shifted his main attention to the cultivation of the fourth layer of the Mixed Yuan Spirit and Demon Skill, and after more than half a year of hard work, he finally mastered this obscure Xuan-level mental method, and under its powerful effect, the aura and demonic energy in his body became increasingly condensed.

At this time, he had reached the peak of the tenth layer of qi refining, and he would break through to the eleventh layer of qi refining at any time, but the more he reached the late stage of qi refining, the more he had to work steadily and steadily, so as to lay a good foundation for breaking through the foundation building period in the future.

Shi Dong was not in a hurry, anyway, he had already washed the Earth Milk Spirit Spring, and there was still a large amount of medicinal power in his body, so he simply used the Mixed Yuan Spirit Demon Skill to slowly refine it. In this way, the aura and demonic qi in his body became more and more refined, overflowing as they operated in the meridians, and continued to merge into every cell, which made his physical strength steadily improve.

So he struck while the iron was hot, and simply practiced the Brahma Sage True Demon Skill improved by the master every time he finished using the Mixed Yuan Spirit Demon Skill, that is, the body forging technique, and the effect was not small, the muscles and bones and body became stronger and stronger, and with the power of the flesh alone, a punch could easily shatter the mountain stone.

Shi Dong was overjoyed in this way, according to this trend, wouldn't his physical body have to be comparable to the demon clan in the future? Even now, his physical strength has far surpassed that of monks of the same level, and if he can fight in close combat, the lethality to the enemy will be even more terrifying.

He simply spread his temperament in this extremely yin hole, broke into the sinister place full of powerful ghosts, and did not use his true qi to protect his body, and fought completely by his physical body, as a result, he fought to the death several times, and after killing thousands of powerful ghosts, his physical combat level soared. It's not far behind those monks who are purely cultivating their strength. The cost, of course, was that he was seriously injured several times. Fortunately, he had Zhi'er in his hand to heal his injuries, and he recovered quickly, otherwise he would have really missed a big incident.

Of course, Shi Dong didn't just do this to exercise his physical combat ability, he killed nearly 10,000 powerful ghosts in half a year, and used them to refine ten ghost spirit pills with mysterious copper lamps, and then used them to refine the qualifications of the spirit ghosts in his hands.

At the beginning, several spirit ghosts had already been promoted to the tenth rank of the Yellow Rank, and they were not far from the Xuan Rank. Under the urging of the ten ghost spirit pills, the light spirit ghosts, bloodthirsty strong ghosts, and six Qi gathering ghosts were all promoted to the first rank of the Xuan Rank.

As a result, the size of the light ghost doubled, and the light mist turned into a fierce white ghost, and the body also gave birth to fine scale armor, which came and went like a white lightning, and the speed was doubled compared to before.

This can make Shi Dong ecstatic, it seems that every time the spirit ghost advances to a big level, it will produce earth-shaking changes, and the current light spirit ghost is more than twice as powerful as before.

Happy, go and see the bloodthirsty Hercules after the promotion. But I was taken aback, and I saw that its size became even larger. He used to be two feet tall, but now he has become three feet, and his body is covered with black armor with barbs, and the armor is shining with blood, which is very scary.

This was not the end, its left hand conjured up a heavy black shield, which was also covered with barbs, and its right hand became unusually thick, and with a wave of the earth-shaking hammer equipped with Shi Dong, it could actually cause a gust of wind.

Judging from the momentum alone, this bloodthirsty Hercules has already increased its strength considerably, and it is at least twice as strong as before.

Shi Dong wanted to see how powerful it was, so he ordered it to break into a group of three hundred ghost soldiers at level 10, but those ghosts were so frightened that they fled in all directions, and they didn't dare to fight it at all.

The bloodthirsty powerful ghost was furious, his eyes flashed red, he took a deep breath and roared, and a circle of ripple-like qi waves rushed in all directions, and suddenly shook all the powerful ghosts within more than ten zhang around it, and saw it shake the ground with a hammer in his hand, and a shock wave visible to the naked eye rushed out, and there was a huge ravine on the ground that was more than thirty zhang long, three feet wide, and two feet deep, and the ghosts naturally turned into ashes wherever they passed.

This Shi Dong opened his mouth wide in shock, and he didn't close it for a long time, obediently, isn't this the overlord slashing trick after the light spirit ghost merged with it before? How can it use it on its own?

Immediately, Shi Dong happily turned somersaults, called the bloodthirsty strong ghost with a somewhat sluggish breath to him, and took out a large handful of ghost feeding pills to reward him, it seems that this promoted bloodthirsty strong ghost has really increased his strength greatly, how can he not be ecstatic.

With greater expectations, Shi Dong drove the light ghost and the bloodthirsty strong ghost to merge once, and as a result, a murderous huge ghost appeared in front of him, and with a move of the overlord, the ravine on the ground suddenly became three times larger, becoming a super ditch more than a hundred zhang long, one zhang wide, and six feet deep, as if a canyon had been cracked in the ground.

Looking at this big ditch in amazement, Shi Dong reassessed the power of the current Overlord Slash, which should be roughly equivalent to the strength of a monk in the middle stage of foundation building.

According to his understanding, the strength of the monks of the Demon Demon Sect is divided according to the realm as follows-

Monks in the Qi refining period generally open stone cracks, and the attack range generally does not exceed more than a dozen zhang;

The monks in the foundation building period can create huge ravines of dozens or even hundreds of zhang, and have the terrifying power to change the appearance of a small mountain;

As for how powerful the Jiedan Ancestor is, Shi Dong has never seen it with his own eyes, but it is estimated that he can at least cut off the peak of one of the peaks of the Demon Demon Gate.

However, the above is just a general situation, a monk like Shi Dong who has a hole card against the sky will often have the strength to cross the rank, such as the overlord slash after the combination of two spirits and ghosts, which is already close to the power of the monk in the middle stage of foundation building.

With a great surprise, Shi Dong checked the upgraded Liuren Qi Gathering Ghost again, and found that this spirit ghost was much stronger than before, the spell force field was expanded to a range of twenty zhang, and the buff effect had also become 30%, which was another big surprise, which made Shi Dong so beautiful that the snot bubbles were about to pop up.

In the previous battle, this Liuren Qi Gathering Ghost was a weakness, and it couldn't withstand the enemy's onslaught several times, but now it has been strengthened so much, and it is naturally a great help to Shi Dong.

Now Shi Dong can be regarded as having tasted the sweetness of the way to resist ghosts, it turns out that the Xuan-level spirit ghosts are so much stronger than the Yellow Order, as long as the monk has one or two Xuan-level spirit ghosts in his hands, he can simply walk sideways in the same level, there is a world of difference between the Xuan-level and the non-Xuan-level, not to mention that he now has three Xuan-level spirit ghosts at once, if it is known by others, I am afraid that I will be so envious that my eyes will fall out.

Happy to be happy, and then Shi Dong became worried, he used to have a three-headed spirit ghost, and others knew that it was only a yellow level, but now it has become a three-level Xuan level, and he is a fool who knows that he has a cat in his hand, and he can raise the spirit ghost to a higher level.

After pondering for a long time, Shi Dong knocked on his brain, scolded himself for being stupid, and simply cultivated three more ghosts, pretending to be the previous one.

Fortunately, he has a mysterious bronze lamp, and it is not a problem to cultivate spirit ghosts, so he improvised to catch a large group of ordinary ghosts, let them swallow the ghost spirit pill and then fight each other, and slowly cultivate spirit ghosts.

After tossing and turning like this for almost three months, I got a light ghost, a strong ghost, and an archer ghost. (To be continued......)
