This last rune is indeed very difficult, because it is extremely complex and profound, without a little understanding, even if it is ten thousand years, it will not be able to comprehend, a thousand runes together cost Wu Kun ten, but this one rune wastes as much as Wu Kun three, which shows its difficulty.

Listening to Wu Kun's understanding of the last rune, plus what he had explored over the years, Long Ao's frowning brows slowly relaxed, and when Wu Kun told him all his understanding, Long Ao suddenly realized!

He slapped his thigh hard, and then shouted, "I didn't think of it in the first place!"

Wu Kun was frightened by this sudden shout, Long Ao was so excited!

Can Long Ao be excited? This is a problem that has plagued him for nearly 10,000 years! 10,000 years have not been solved, and Long Ao's comprehension is also poor enough.

After getting Wu Kun's experience, Long Ao immediately disappeared without a trace, he directly tore open a corner of the space, and then got in. He wanted to personally verify whether Wu Kun was correct.

The result is certain, because Wu Kun himself has completed his cultivation in this way, but now Wu Kun is forgotten in this place alone, and no one receives him.

Now the situation is special, many people are on the front line of resisting the gray creatures, and big clans like the Qinglong clan are all involved, so the Qinglong clan's station in the rear is almost empty, and only the patriarch will come back occasionally.

Wu Kun walked around the Qinglong clan's station, and indeed didn't see a single person, maybe the situation was special today, so everyone went to the city wall.

"I'd better go and walk around on my own. ”

Wu Kun walked all the way, inquired all the way, and finally found the station of the White Tiger Clan, this is his current goal, Wu Kun has tasted the sweetness brought by the bloodline of the Four Saints, just the bloodline of the Qinglong and Vermilion Bird Clan has brought Wu Kun a huge improvement, if the bloodline of the Four Saints is fully awakened, the effect of the improvement is terrifying!

This can be regarded as an extremely quick and easy way to improve strength, so how can Wu Kun let go of such a simple way?

But unfortunately, the station of the White Tiger Clan was also empty, and all the people seemed to have disappeared because of something, so Wu Kun could only go to the city wall to find them.

Sure enough, exactly as Wu Kun guessed, an extremely fierce battle was going on on the city wall, almost all the strong people in the rear were involved, and the gray creatures were launching an unprecedented fierce attack!

The current situation is that the demon clan defending the city is extremely difficult, and many places are already in a hurry, and even gray horizontal houses have climbed the city wall!

Wu Kun never saw when the demon clan encountered Ruci's predicament!

Without saying much, Wu Kun rushed up directly, and a ball of fire rose from his hand, turning those gray creatures that rushed up to the city wall into ashes!

Many god-level gray creatures had already disappeared into the world before they had time to struggle! Such a fast speed, even those people of the demon clan did not reflect it!

It's too fast, it's too terrifying! At this temperature, even those demon beasts have an extremely palpitating feeling! They can be sure that even if they get a little bit of this kind of flame themselves, the consequences will definitely not be any different from these gray creatures! It must be a dead word! And they all disappear silently!

The crowd gasped!, however, it was only a momentary moment of surprise, and they had more important things to do, which was to face the walls and scare the gray creatures that were about to attack!

Everyone, no one can be idle, the number of gray creatures in front of him is too much! Wu Kun has been fighting with gray creatures for some time, but he has never seen so many gray creatures!

All this was so sudden that many strong people fell into an inexplicable bloody battle, and each demon beast showed its own true body, facing the siege of several strong people at the same time.

It is very likely that this line of defense, which has not been stabilized for a long time, will be broken in a short period of time! And the price will be extremely heavy.

Even if you retreat, it will take time, and time must be fought in the battle with the gray creatures, and if you hastily withdraw without preparing anything now, the losses may be even greater!

The demons must hold off this wave! These gray creatures must be repelled! Otherwise, everyone will be in an even greater crisis!

A lot of unfamiliar faces came from the rear, this was a reserve to deal with emergencies, and it was specially prepared by the demon clan for this enhanced version of the attack.

Countless demon clan powerhouses rushed to the head of the city to support this precarious defense line, and the casualties on the city wall were extremely heavy!

As Wu Kun saw, there were no less than ten god-level powerhouses who had fallen, and there was even a god-king level powerhouse who was dying, if it weren't for Wu Kun's shot, the loss might have been even greater!

This is still in the case of Wu Kun, but Wu Kun is alone, how big of a place can he shine on? Now Wu Kun can't leave at all, he can't go to support other places, because just staying in this one place will keep him!

Even if Wu Kun's mana is now surging, he can completely crush all the god-king-level powerhouses, but as soon as Wu Kun makes a move, he attracts a large number of gray creatures, most of which are strong! Moreover, they still have a Saint-level treasure in their hands!

Wu Kun was targeted by a special group of gray creatures! This group controlled powerful Saint-level treasures, specializing in sniping some outstanding people in the demon clan and assisting the attack of the gray creatures!

Whoever is at the top of their game will be targeted by this special group and then eradicated! They are like snipers with a gray biological clock.

Wu Kun is now in a big trouble, this group has a clear division of labor, and there are many of them, it is useless to kill a few, that holy rank treasure is still operating, and it is constantly attacking himself.

This is a big ding, the sound of the ding is excited, if you are shaken by this big ding, it will produce a sense of dizziness, extremely troublesome, and those strong people will take advantage of Wu Kun's dizziness to launch a collective attack.

All kinds of treasures and weapons are rushing to the face, carrying the overwhelming momentum, which is quite terrifying!

Wu Kun had dodged several such attacks, because that Kouding had never hit him, and his actions had not been affected.

The battle that Wu Kun faced attracted a lot of attention, and the people of the demon clan were all worried about what happened to Wu Kun, once they were targeted by this group, few people would be able to survive. Even if a powerhouse of the Holy Rank encounters such a group of jackals, tigers and leopards, he has to take it seriously.
