Several people persuaded Zhang Hanyan to let go of her knot, and under her introduction, with the help of a foundation-building monk of Qingxuanzong, she spent six hundred spirit stones to buy three third-order lower grade spirit runes.

Qi cultivation period cultivators use third-order spirit runes, because the mana strength is insufficient, they can't exert all the power of third-order spirit runes.

According to Zhang Menglong's experience, among the four of them, Zhang Mengqin and Zhang Hanyan, the two daughters, have been in the ninth layer of qi cultivation for a longer time, and their mana is also more refined. As for the fourth uncle himself, he is over eighty years old, and his mana and energy have gone downhill, and he may not be able to compare with Zhang Zhixuan, who is young and strong.

Therefore, in order to better exert the full power of the third-order spirit runes, these three spirit runes were assigned to Zhang Zhixuan and the three of them.

The main task of the fourth uncle is to control the formation, and without the siege and protection of the formation, several people are not the opponents of the demon beasts in the foundation building period at all.

The power of the firehorn is very strong, and it is difficult to control it with the Storm Formation.

So in order to better deal with it, Sibo also had to change the formation.

He sold the Storm Formation to Fang Shi, and then bought some precious materials, pasted more than 200 spirit stones, and re-refined a set of third-order formation earth dungeon golden array.

This kind of formation can turn the soft soil into hard fine iron, and unless you use a water attribute spell, you can restrain the formation and break the formation successfully.

And a few people clearly know that it is impossible for the firehorn to use water attribute spells, although this formation has obvious shortcomings, it is obviously not sold for a large price, but it is obviously very cost-effective to deal with the firehorn.

The four of them rested for a few days, and saw that the fifteenth uncle could not recover for the time being, so he let him recuperate in the Hanyan Cave Mansion, replenish some consumable materials, and venture into the southern wilderness for the second time.

The firehorn is short-tempered, its weakness is very obvious, like the ordinary bison in the countryside, whenever it sees red objects, it is prone to rage, and is particularly sensitive, and must be trampled into powder before it will give up.

Taking advantage of its weakness, Zhang Zhixuan and the four of them came to the vicinity of the spiritual vein where it was entrenched, first arranged the formation, and then hung a three-zhang high red flag high in the formation.

As soon as the red flag was hung out, the firehorn bull rushed down from the mountain in a rage, easily entered the ambush formation, and a stream of flames erupted from the huge mouth, burning the red flag completely.

Just as it was about to leave, a wall of earth rose from the ground and held it back.

The firehorn bull slammed into the earthen wall in a rage.

With a boom, dust flew in the formation, and a stream of spiritual light was released from the earthen wall, turning into a copper wall and iron wall, blocking the fire horn cow in the middle.

Seeing this good opportunity, Zhang Zhixuan and the three of them sacrificed their flying swords, and the three flying swords flashed brightly, and they were immediately cut on the head of the firehorn cow.

It's a pity that the skin of the demon beast like the Firehorn Cow is rough and thick, and although the head is hit by three flying swords, the mana of the three people is low, and it does not bring fatal damage.

The three flying swords, just breaking through the fur of the Firehorn Ox, became the end of the crossbow, leaving only a few wounds more than an inch deep.

An injury of this magnitude is not important to the firehorn at all, and it is not a hidden danger.

The firehorn roared in a low rage, and a pair of horns glowed with spiritual light, which quickly condensed into three huge fireballs.

The fireball was more than three feet in diameter, and extremely hot flames gathered inside.

"Be careful, it's the demon beast's natal true fire, you can't let it attack the array. Quickly use the third-order spirit rune to block this wave first. "The fourth uncle has been manipulating the formation, he can see it very clearly, and when he sees danger, he immediately reminds him.

The fireball was extremely fast, and in an instant, it had already flown out of a distance of more than a dozen sheets, and hit the three people respectively.

The three of them sacrificed the third-order low-grade golden light shield spirit rune in their respective hands, and the spirit rune burned lightly, turning into a huge shield, protecting the three of them inside.

The fireball hit the golden shield and exploded into a strong explosion, although Zhang Zhixuan and the three of them did not exert the maximum power of the third-order spirit rune, but they also blocked most of the fireball inspired by the firehorn.

A flame full of spiritual energy passed through the barrier of the golden light cover, and poured down towards Zhang Zhixuan.

Zhang Zhixuan lightly used the light body technique, his body was like a feather, he took a few steps back, and then sacrificed the Purple Cloud Flag.

The Purple Cloud Banner turned into a purple spirit cloud, blocking the remaining flames from the outside.

Seeing that the blow didn't work, the firehorn roared furiously, and a white light came out of his mouth, slamming into the hearts of the four people.

This loud roar, like a lion's roar, directly hit the spirit of the four people, and after the white light, the four of them fell to the ground one after another.

Especially the fourth uncle who controls the formation is the most critical, as soon as he misses here, the strength of the formation will immediately decrease sharply.

The firehorn struggled twice before breaking free from the iron wall and regaining its freedom.

It glanced at the four of them angrily, and sucked hard from its huge mouth, and a gust of wind blew over, trying to suck all four of them into its mouth and swallow them.

At this time, the four of them had recovered some energy, Zhang Zhixuan's eyes moved, he took out a red bead from his waist, waved his hands, and slammed it at the firehorn.

The firehorn's mouth opened, and without looking at it, he sucked the red orb into his mouth.

There was a violent bang, like a dull thunderbolt exploding in everyone's ears.

The red bead is the killer fire thunder bead in Zhang Zhixuan's hand, this is a one-time third-order magic weapon, and its power is much more than that of the third-order spirit rune.

This fire thunder bead exploded in the demon beast's mouth, and with a single blow, it hit the weak point of the firehorn cow, shattering its throat to pieces, leaving a huge wound.

The firehorn softened on all fours, fell to the ground with a thud, and lost its breath on the spot.

The four of them glanced at each other, and couldn't help but be a little lucky, if it weren't for the lack of wisdom and experience of the firehorn ox, it devoured the fire thunder bead and was killed on the spot.

According to its supernatural powers, the four of them may not have a chance to win today.

In the lower third-class realm, compared to the rough skin and thick flesh of demon beasts, and the unique physical conditions, the only advantage of human monks is their wisdom.

It is precisely because of their wisdom that Zhang Zhixuan and the four of them were able to formulate various tactics to restrain demon beasts, and they were able to hunt third-order demon beasts across the great realm.

If you face a foundation building period monk, although the four of them rely on the formation and have the power to protect themselves, it is difficult to plot against a cautious foundation building period monk.

Moreover, the monks in the foundation building period have high mana, fast speed, and initiative, unless they are trapped in the formation, otherwise Zhang Zhixuan and the four of them basically have no chance of winning.

The four struggled to their feet and began to clean up the battlefield and collect the loot.

The value of the firehorn cow exceeds that of the flying fire toad, and it is worth 1,800 good deeds in the Qingxuan Sect, and the most valuable thing on it is a pair of horns, but this thing needs to be handed over to the sect to exchange for good deeds.

In addition, the best material on its body is the skin on its body, and the fur on this body is enough to refine three pieces of leather armor, at least above three hundred spirit stones.

Secondly, its essence and flesh are also quite valuable, and even the bullwhip is also a great yang thing, and some monks like it very much, and they can often pay a lot of money.

After packing up the materials on the firehorn cow, everyone searched near the firehorn cow's nest and found five fiery red spirit stones, and there was a trace of warmth in the spirit stones.

This kind of treasure is a medium-grade fire spirit stone, a medium-grade spirit stone, which can not only provide a large amount of spiritual energy, but also be used to arrange formations and provide a large amount of energy. It can also be used to cultivate spiritual veins, and the effect is far better than that of lower-grade spirit stones.

Even if the entire Zhang family has accumulated only twenty or thirty medium-grade spirit stones, it is a pity that the spiritual veins in the cultivation spirit field have been used up.

The fourth uncle put away the five medium-grade fire spirit stones, looked around carefully, and said, "It seems that there is no elixir nearby."

This place is far away from Qingxuanzong, there is no firehorn cow, and I don't know what demon beasts will take the opportunity to occupy the spiritual vein, so we should act immediately and hurry back to Qingxuanzong's station. ”
