It is worthy of the existence of the pinnacle of the Yuan Infant, under the joint efforts of Lei Dong and the Demon Dragon Soul of the Underworld, it took several hours of refining before he completely suppressed the "Set Sail without Watermark" and carved away its sanity. At this moment, those mysterious formations engraved by the ghost banner were activated with all their might, and the rules were constantly broken into the Yuan Infant.

Refining the Immortal Demon Venerable is really a thunderous effort. It took several days of hard work to completely refine it into a pot-bellied cannon ghost. And the power of the thunderbolt is also consumed for it, and the thunderbolt of the god moves and summons it from the ghost flag.

The body shape has not changed much, but the appearance has been turned upside down.

From the barrel to the belly, the body is covered with a layer of black armor of hòuhòu, which is strong and elastic. In particular, the barrel that represents its attack, faint and heavy, reveals a suffocating danger.

Looking at its breath, it was a little strange, that is, it was like a breath that surpassed the peak of Jindan, and there was also some breath of the Yuan Infant level. It's like somewhere in between.

Ah Chou, who devoured the flesh and blood of the demon king and advanced to the middle-level ghost king, slashed out the L knife at this pot-bellied cannon ghost under the order of the thunderous divine thought.

Between the black sword flashes, the hòu-heavy body of the pot-bellied cannon ghost was slashed upside down and flew out. The armor layer on his body had already been cut out of a half-foot-deep knife mark, but in the next moment, the ghost clan's unique ghost body played a role, and the knife mark healed quickly at a clearly visible speed, and the knife mark disappeared after only a dozen breaths.

"Good, good baby. Lei Dong exhaled deeply and laughed, just now, although it only exerted three or four percent of its strength, it was not something that the Jindan level could resist. From this, it can be semi-determined that this pot-bellied cannon ghost refined by the Immortal Demon Venerable Yuan Ying should far exceed the Jindan level.

Moreover, the defensive performance of this pot-bellied cannon ghost has far exceeded Lei Dong's expectations. Originally, when designing this class, Thunderbolt sacrificed all of its abilities to focus on the barrel and belly. It's all about how to make it more powerful Nether Cannonballs in one hit.

This design seems to ignore defense, but in fact, the pot-bellied cannon ghost performs well in terms of defense performance. In fact, the reason is very simple, whether it is a big belly or a gun barrel, Lei Dong must give full play to their flexibility and hardness. Otherwise, either the big belly is blown up by the Nether Ghost Qi, or the barrel is blown up at the same time as the Nether Cannon is fired.

In this way, it can be regarded as indirectly strengthening the defense of the pot-bellied cannon ghost. Of course, in terms of speed, there is really no way to compliment it. Lei Dong made it fly a test lap, and although it was light and fast, it was actually not much faster than an ordinary Jindan mid-level cultivator, far below the level it was in. Fortunately, the speed of the pot-bellied cannon ghost is not what Lei Dong is pursuing, and it is what Lei Dong needs to give full play to the power of the cannon fire. But this time, Lei Dong didn't let it run to Xuanyuanzi to test the gun. This is a secret weapon refined by Lei Dong, and according to the power of the Jindan Cannon Ghost, the power of this new Cannon Ghost will definitely be unexpected.

There is not much time, and Xiao Yu will maintain the Netherworld Black Formation for three more months at most. And Xuan Yuanzi is estimated to be waiting hard, waiting for Xiao Yu to hold on. Lei Dong also put down the research and development of ghost soldiers for the time being, and began to focus on manufacturing a large number of practical troops.

The next two months of thunderous work day and night, extremely hard to refine batch after batch of ghost soldiers. The first choice is not the pot-bellied cannon ghost, but the suicide ghost. The Suicide Ghost class seems to be wasteful, it is nothing after a single bombing, and it is easy to be knocked out remotely when it is close to the enemy. It can be used repeatedly like the pot-bellied cannon ghost.

However, the power of a suicide ghost's explosion is three times that of a pot-bellied cannon ghost, and it is very fast. This is the most cost-effective class in a battle against such a god-level monk. Of course, consumption is a must, but if the pot-bellied cannon ghost is a heavy artillery, then the suicide ghost is basically equivalent to a missile. Of course, Lei Dong is not yet extravagant enough to use high-grade or top-grade spirit ghosts to refine suicide ghosts. After all, no matter how powerful a suicide ghost is, it is also a consumable.

Of course, the pot-bellied cannon ghost that surprised Lei Dong was also the highlight of this battle. The Cannon Ghost is very strong, especially the Cannon Ghost that can borrow the Netherworld Black Evil Array as a cover. Because they can unleash the power of the pot-bellied cannon ghost without having to be chased by the enemy. ...,

Under Lei Dong's concentration, Lei Dong refined a total of 50,000 primary suicide ghosts, 30,000 primary pot-bellied cannon ghosts, and 30,000 primary gas storage ghosts.

Especially the 30,000 junior qi storage ghosts, but it took Lei Dong countless Nether Ghost Qi to replenish them. If you want to change to ordinary people, I am afraid that you will not be able to do and persist. And Lei Dong Gu Hao used to use the Demon Emperor Transformation to squeeze out the true yuan in the body's "Set Sail without Watermark" when he was cultivating before, and his body had long been accustomed to this kind of squeezing, so he barely persevered. But the results are also fruitful, 30,000 qi ghosts are enough to allow each pot-bellied cannon ghost to fire ten underworld cannon shells.

As for the other types of troops, Thunderbolt has not been refined for the time being, and they are not very suitable for this level of battlefield.

After all the preparations were in place, Xiao Yu had also insisted on the Netherworld Black Formation to the point where it was about to reach its limit, and in her words, at most, it could last for a month.

A month, that's enough.

The first batch of ten suicide ghosts flew out of the black evil array, each of which opened a distance of dozens of zhang and flew towards Xuan Yuanzi at a normal speed unhurriedly.

Xuan Yuanzi, who had already been tortured like a frightened bird, reacted at the first time. It's not the first time he's seen those suicidal ghosts. For this kind of little ghost, Xuan Yuanzi is quite jealous, fast speed, and self-explosion power is not bad.

There are only ten of them, lined up in a straight line, but this straight line is stretched out hundreds of zhang distance. This gave Zhi Yuanzi a headache, a very headache. With such a scattered distance, of course, it is impossible to use a powerful spell to fight, and such a cost performance is something that Xuan Yuanzi cannot afford.

But being approached by them and blowing himself up, although he can stand it completely after being prepared, it will consume a lot.

In this way, what is placed in front of Xuan Yuanzi is to either transfer, or use exercises such as the finger strength with the minimum consumption, and destroy them one by one by clicking. But he knew very well how cunning the kid surnamed Lei was on the other side, and it was absolutely impossible for him to make it easy. Counting the time and consumption, that Netherworld Black Evil Array is almost unable to support it, right? Hmph, once this formation collapses, it will be the end of this kid surnamed Lei, and the real person will let you know what it means to live rather than die.

This is already Xuan Yuanzi's last psychological comfort, if it weren't for this thought to maintain him, he would have been harassed all the time for nearly two years, and he would have been unable to hold on to rushing in desperately.

Indeed, as expected, Lei Dong will definitely not let him have a good time. After the first row of suicide ghosts flew out for dozens of feet, the ten suicide ghosts in the second row followed closely, still flying unhurriedly. Dozens of feet later, there are still ten suicide ghosts. Looking at that posture, it seems to be endless in the back.

Xuan Yuanzi secretly said that it was not good, and hurriedly pointed out his fingers. A slender white finger roared away, so fast that it was hard to react and dodge.

As expected, the targeted suicide ghost exploded out of thin air, and the wave of qi swept more than a dozen feet away.

But before Xuan Yuanzi could start to get complacent, the remaining suicide ghosts began to accelerate and sprint. After speeding up, the speed of the suicide ghost skyrocketed several times, and every breath could sweep twenty zhang away. For a few miles, at most, it will be a small twenty breaths of time to bump into Xuan Yuanzi.

But Xuan Yuanzi is not a vegetarian, although his state is extremely poor, he is also a god-level monk. The well-maintained fingers flew up and down, and the fingers that could pierce through the rock and iron hissed and struck away.

Boom, boom, Rao is those suicidal ghosts are extremely fast, but under Xuan Yuanzi's perverted thoughts and reactions, they are still killed one by one with accurate points. However, the frequency of suicide ghosts has also begun to increase. The row of suicidal ghosts in the back began to rush out at a direct acceleration. And the distance between each row is also twenty zhang.

In this way, it is equivalent to every breath of time, and a row of suicide ghosts who are not afraid of death rush out. It goes on and on, as if it never ends.

No matter how powerful Xuan Yuanzi is, there is a limit. Low consumption, fast speed, and extraordinary power, his time per breath is at most seven or eight hits. And the more suicidal ghosts appeared, he was under great psychological pressure, and his hit rate began to decline.

Moreover, Lei Dong also began to command accurately, and the dozens of suicide ghosts at the front, under the precise command of Lei Dong, began to perform tactical evasion actions, and in the state of extreme speed flight, they began to shake in a slightly small range. Although it slowed down slightly, it made Xuan Yuanzi's hit rate even lower.

Of course, if Xuan Yuanzi can be ruthless and cast a large-scale spell, he will ensure that he can kill all the remaining suicide ghosts. But he didn't dare, and he couldn't afford the loss.

At the same time, the thunderous pot-bellied cannon ghost formation also began to exert its might. The Big-bellied Cannon Ghost began to bombard outside the Netherworld Array with a hundred. The salvo of hundreds of pot-bellied cannon ghosts is also quite powerful.

Listening to the roar in his ears and looking at the cannonballs that attacked like meteors, Xuan Yuanzi began to curse in his heart. He didn't dare to carry it hard, he didn't dare to be stupid, so he immediately gave up the attack on the suicide ghost, tore through the space, and teleported to the other side. This time, he teleported eight or nine miles away. In normal times, Xuan Yuanzi must be very relaxed, but this time, he felt a little struggling.
