Lu Ning was still calculating the offensive and defensive situation at the head of the city for a second, and the next moment he had already jumped out and blocked in front of Tianyu and the others.

The ancient sword in his hand faintly spread ripples, turning into white sword qi and sweeping vertically and horizontally.

In the air in front of him, several small black balls suddenly appeared. If it weren't for Lao Lu taking the first step and slashing off these small black balls with his sword, they might have hit Yu Tianyu and the others by now.

These small black balls are extremely fast, and there is not a trace of the sound of breaking through the air, which is difficult to guard. Yu Tianyu and the others returned victorious, and they didn't notice the sneak attack at all.

As for Lu Ning, after all, he is ** lake, and he is extremely sensitive to demonic energy.

In a hurry just now, Lao Lu first blocked the insidious sneak attack, and when he looked down, he was surprised. A dozen balls that had been cut in half at their feet, the size of their thumbs, with a blue-green color on their profiles and some juice dripping from them. There was a faint astringency in the air.

Huh? Like a kind of fruit?

Yu Tianyu and the others were still stunned, and Lu Ning remained vigilant and frowned. Where did this attack come from? There were no monsters to be seen on the battlefield except for the fire-tailed ox. Is it invisible?

"Retreat!"

Lu Ning shouted.

While thinking in his heart, he ordered Yu Tianyu and the others behind him to retreat first. This was a method that Lu Ning had not seen, that is, a demon that he had not seen in the previous era, was on the battlefield.

Out of consideration for training his subordinates, Lao Lu did not personally go down to deal with the copper-headed fire-tailed ox, but only told the enemy's intelligence clearly. The path of cultivation is not an idyll of warmth, and in many cases killings and dangers occupy most of the scenery of this path.

Therefore, as long as there is an opportunity, Lao Lu will throw his hand and let this group of cultivators deal with the monsters by themselves. It's dangerous to do so, and it's easy to die, but it's the most indispensable part of the spiritual path.

People with strong hearts will progress faster and stronger through life and death struggles, just like a good seedling like Yu Tianyu. And those who are not strong-willed... I just complain that you are not suitable for this path, and it is better to eliminate it as soon as possible.

Lu Ning's educational ideas are more extreme, he is originally a demon. But no matter how extreme it was, he at least knew that he couldn't let his men die in vain.

In the face of the big demon who doesn't know the details at all, and then let these cultivation rookies stubbornly, it will be a great loss of their lives. This kind of dangerous work of traveling to the mine is Lao Lu's job as an instructor.

He stood in front, and Yu Tianyu and the others cautiously pulled the bull demon back. If conditions permit, of course, everyone wants to bring this big guy back with all beards and tails. Yu Tianyu didn't understand the identification of spiritual materials, but this bull demon was obviously full of treasures. If it can really be domesticated into a mount, it will be beautiful to think about.

But how can things be so simple, the five copper-headed fire-tailed oxens are the precious combat power of the emperor's men, and it will be very heartbreaking to lose any of them. This powerful demon general just disdains to play small tricks, but he is not stupid enough to know how to cover up.

There was another burst of demonic energy, and Lu Ning, who was on guard, saw clearly this time, and the black fruit flew out from the forest in front. Previously, these five bull demons came out of this forest to attack the city gate. But why is this forest so close to the city walls?

In order not to be attacked by demons and to broaden the horizon, the perimeter of the coastal city wall is as strong as all ancient siege battles. Lightning had organized a long time ago to clear dozens of kilometers of dense forest in the surrounding area. But why is this dense forest so close to the city walls?

Before I could think about it, the situation changed again. Because the black fruits that come at a rapid pace keep shooting out of the forest. The large number and wide coverage made Lu Ning's scalp numb.

He raised his sword and shouted, "Everyone, withdraw!

Lao Lu is everyone's instructor, and he has always said the same. With such a snort, all the squads involved in the attack on the bull demon stopped one after another.

The soldiers at the head of the city threw out the rope very cooperatively, and the cultivators jumped into the air, pulled the rope with a little force, and returned to the relative safety of the city.

Only Yu Tianyu couldn't give up the bull demon in his hand, and he hesitated to hold the copper ring. This delay could cost him his life, and several black fruits bypassed Lu Ning's sword qi and shot towards various parts of Tianyu's body.

Yu Tianyu was calm, his body moved left and right, avoiding most of the attacks. The black fruit hit the ground behind him, leaving small black holes like gun's eyes.

However, the arm he was holding the bull demon copper ring could not move, and a black fruit with a tricky angle directly hit the Quchi point of his right arm. If it was a bullet, fighting for the physique of a cultivator, Yu Tianyu might not be able to endure this blow.

But at this time, he was like being struck by lightning, and he only felt that something in his right arm was frantically draining his life force, and a feeling of impending calamity spread throughout his body along the meridians.

He should have died on the spot within a few breaths, but suddenly his right arm was light, and Yu Tianyu was carried back to the city wall with his clothes. It turned out that Lu Ning saw that he was in a dangerous situation, and directly cut off his arm with a sword, saving his life.

Yu Tianyu covered his wounds, and for the time being, he did not have the pain of a martial artist losing an arm, but was glad that he did not die. He saw several of his fellow believers, who were not checking for a moment when they were retreating, and were hit by the black fruit. They all fell, struggling and wailing in pain.

In such a short period of time, the flesh and blood of their bodies dried up. What's even more terrifying is that before the screaming can stop, the black fruit has already burst out. This seed absorbs the flesh and blood of the living and grows half the size of a man.

It is supposed to be an immature dryad, with tiny branches forming a distorted face. It pulled the roots out of the corpse, looked around, and staggered away from the forest.

The soldiers angrily shot at the dryads, causing the leaves to fly and fall, but this did not hurt the dryads at all.

"Use fire!"

Lu Ning reminded loudly.

The soldiers woke up from a dream, pulled out their flames, sprays, and shoots several dragons at the tree spirits.

The two dryads let out a grotesque, high-pitched scream and rolled around on the ground. The soldiers would not let it go and continue to greet with flames. After a few rounds, there was a crackling explosion, and the trunk of the dryad cracked from top to bottom, and finally stopped struggling and turned to ash.

Only one Dryad escaped the range of the flames because it was far away. Like a torch, it flew towards the forest. Screaming as he ran. The fire was burning in the branches, and it was clear that the dryad was dying.

But as he approached the forest, there was a sudden flash of green above the forest.

A green demonic aura enveloped the burning dryad, and the flames on its body were extinguished instantly, and all burns were quickly recovered. The tree spirit ran back to the edge of the forest, then dug its roots deep into the earth. In this way, it became a part of the forest again, and there was no separation from each other.

Also withdrawing were five fire-tailed oxen, which were besieged by the practitioners of the seashore, and all of them were more or less slightly wounded. But they also recovered in the green demonic aura, and after a few breaths, they became alive again. They gouged their hooves and spewed fire, and it looked like they were about to storm the walls again.
