The group had no choice but to go back to the room to recite the Fa recipe, and the disciples of the other elders were all in a separate room.

Only Elder Su Chang's disciples of more than twenty people crowded together to lay on the floor, after all, even if they were dissatisfied, they didn't dare to live with Su Chang.

There's no way, the qualifications are poor, it's already very good to be able to cultivate, at least get rid of the fate of mortal dust, squeeze the floor and squeeze the floor.

However, without the cultivation of the lower grade spirit stones, just reciting the recipe is like teaching the chef to cook, but not giving the chef the ingredients a reason, is there a fart?

After all the disciples left, Su Chang watched this group of iron-winged cranes.

To be honest, Su Chang's space armband had countless top-grade spirit stones, but he couldn't give them them.

After all, he couldn't explain the origin of the spirit stone, and it would not be good to attract the attention of the cultivators, so he could only slowly figure it out.

Early the next morning, a group of disciples came to the door again, only to find that their master was gone, and he disappeared with the iron-winged cranes.

At this moment, Su Chang carved the golden formation on the iron-winged crane's body overnight, and hurriedly took over the task and left the fairy mountain.

What to do down the mountain?

Killing, of course!

In order to cultivate disciples, the Immortal Crane Sect couldn't help but pay the price of one lower grade spirit stone per month for each outer disciple.

In order to cultivate the combat effectiveness and enthusiasm of the disciples, the high-level leaders of the Xianhe Sect also deliberately built several relatively safe trial grounds, so that the disciples could not only fight, but also exchange with the sect for spirit stones with their abilities.

Su Chang's identity as an elder of the outer gate was tasked with "cleaning up the bats".

There is a group of "spirit blood bats" on the branch peak of the North Mountain, these spirit blood bats are fierce and small, and they are good at team crimes, and often select the cranes on the North Mountain to suck blood.

You know, the crane is the foothold monster of the Crane Gate, how can this group of flat-haired beasts absorb blood?

As a result, the outer gate had this task, and every once in a while, there were outer disciples who formed a team to exterminate a group of spirit blood bats.

However, due to the vastness of the North Mountain and the numerous branch peaks, the Spirit Blood Bat is small and sensitive, and it can't be finished, so it has this long-term task.

Twelve iron-winged cranes lined up in the air, Su Chang sat in the cloud sky and stared down, and after a while, he found the location of the mission, driving the iron-winged cranes to descend.

A darker corner of the mountain, overgrown with weeds, and no sunlight penetrates.

Looking at the traces around it, the spirit blood bats here should have been exterminated many times, and then discovered by new bats, and then exterminated, and found again.

In order to train disciples...... The Immortal Crane Gate can be regarded as a painstaking effort, otherwise wouldn't it be good to come directly to a Yuan Infant Stage cultivator and blow up this place directly?

Su Chang suddenly had the feeling of playing games in his previous life, and he was still the kind of master who led novices through the dungeon.

Although the twelve iron-winged cranes only had the strength of the first level of Qi training, their pair of iron wings were increased by Su Chang's countless golden formations.

This is simply the great creation of this group of iron-winged cranes, otherwise who would be idle and have nothing to do, and play with a group of small evil pen carving formations with a layer of qi?

Fighting alone, the electric crane has no opponent.

In groups of three or five, the fire cloud crane is the one who does not let in

But if the number goes up, the iron-winged crane's group attack ability is unparalleled among all crane groups, which is why Su Chang chose them.

Although the number is still small, the more there are in the future, the strength of the iron-winged crane will increase exponentially.

Using twelve iron-winged cranes with a level of Qi cultivation against hundreds of spirit blood bats with a level of Qi cultivation at the fourth level, Su Chang, who was also at a loss, thought about it, and if he swarmed up, even a cultivator in the foundation building period would have to flee for his life in a hurry.

And now, the twelve iron-winged cranes that were carved by Su Chang with the golden formation were all golden, and their own bloodlines seemed to be extracted out of thin air, forming gold armor on their bodies, just like the defense that Su Chang only had in the foundation building period.

Whew!!

The power that erupted under the burning life potential of the twelve iron-winged cranes was terrifying, and ordinary Qi cultivation stage disciples could only control one immortal crane, and only three in the foundation building period.

And under Su Chang's powerful soul path cultivation, these twelve iron-winged cranes didn't make any superfluous movements at all, and they were as obedient as twelve puppets.

In an instant, the golden aura exploded, and the spirit blood bats hidden in the corner of the mountain discovered the enemy, but it was too late.

Whether it is a big tree or a rock on the road ahead, the iron-winged crane array is fearlessly impacting, if it is controlled by a disciple who is not strong in soul thoughts, this group of iron-winged cranes would have scattered and flown in all directions, who would be stupid enough to hit the stone?

The price paid is great, and the gain is also great.

After scrapping the four iron-winged cranes, hundreds of spirit blood bats were crushed before they could react, and more than thirty of them were killed on the spot by the iron wings of the iron-winged crane group.

When the spirit blood bats reacted, they all rushed towards the cranes, and many of them waved their short wings to pounce on Su Chang.

Ding Ding Ding Ding!!

The sound of hitting metal continued to sound, and Su Chang turned a deaf ear to this group of spirit blood bats that attacked him, and even the twelve iron-winged cranes under his control did not make any movement, allowing the spirit blood bats to bite.

Su Chang had studied the attributes of the five elements for countless years, and even if the formation he carved was based on the iron-winged cranes of the first layer of qi training, this group of spirit blood bats of the fourth layer of qi cultivation would not want to kill them for a while.

Gradually, the gold formation runes on the iron-winged crane's body began to surge, and some parts were not protected by the power of the gold formation runes, and they were bitten out of wounds by the spirit blood bat.

This group of motionless iron-winged cranes was covered with spirit blood bats, and when the blood flowed out, it stimulated the tyranny in the hearts of the remaining spirit blood bats, and they quickly tore at the flesh one by one.

The twelve iron-winged cranes did not dare to move under the suppression of Su Chang's soul thoughts.

Su Chang waited quietly until all the golden formation runes poured into the feathers of the iron-winged cranes, and in the next second, the twelve iron-winged cranes burst together.

Countless iron feathers scattered and flew in all directions, and one by one the spirit blood bats were either pierced through their bodies and died on the spot, or they were nailed to the wall, and the worst thing was that they could not die after being cut through their bodies by iron feathers.

Taking out the sack prepared in advance, Su Chang's soul thoughts could no longer control objects in the four-dimensional space, and he could only deign to pick up the corpses of the spirit blood bats one by one.

According to the sect's contribution, a fourth-level spirit blood bat corpse is worth four contributions, and in exchange for an iron-winged crane or a low-grade spirit stone, it requires ten contributions.

After calculating the corpses of one hundred and thirty-six spirit blood bats in the sack, that is, five hundred and forty-four contribution points, which can be exchanged for fifty-four iron-winged cranes or low-grade spirit stones, it can be regarded as a grand slam.

If Su Chang did it himself, he might not have to be so troublesome, but he had to hide his true strength, otherwise it would be too terrifying to use the foundation building period cultivation as a hard anti-spirit blood bat group.

So, for the time being, he can only use these small means to play slowly, but it doesn't matter, he has time to play slowly......
