Four giant swords, four black dragons, slammed violently, the black dragon roared, and the giant sword hissed. The duel between the fierce and domineering, in addition to the turbulence and fury of the immortal power, also has the charm of the rules of heaven and earth, there is no pitch-black black hole, and even the dark clouds are still drifting, and the battle between the two parties has not affected this world in the slightest.

"You can't attack at all! you can't break through my defenses at all!" Armor Tu smiled defiantly.

"So what?"

"You can't help me, since you want to protect your students, then I'll kill them. As long as I live, then they will inevitably suffer from heavenly punishment, as long as I push the boat down the river when the time comes, I don't need to do it myself, they will definitely die, hahaha!"

"Yes, although you have lived for a long time, you really have few means! Look at me, I won't let your soul fly away! Sword! Explosion!" The fierce color on the face of the old man in blue flashed, and the magic trick in his hand changed, and the four giant swords skyrocketed at the same time, turning into four sword walls, sealing the four sides at the same time, and exploding.

A roar sounded between heaven and earth, and two blood-colored figures fell down. One fell straight down on the broken tree, and the other on the top of the mountain.

"The Heavenly Immortal students who are still alive now, immediately hunt down this dragon, you only have three days, otherwise you will be punished by the heavens, quickly!" The old man in blue was already dyed blood-colored at this time, and this roar was even more hoarse.

There were only more than a hundred remaining students, and there were only a dozen or so Heavenly Immortals left, who rose to the sky at this time and flew straight towards the dragon soul.

"It's just some ants, they dare to do something with me, three days later, it will be your time of death!" At this time, the black qi on the dragon soul had disappeared, and its body was less than a zhang, and it flew back to its previous body, the giant tree.

"Lin Bing, you stay here, and I will go in with the Ice Girl. After Mu Lin finished speaking, he flapped his wings behind his back and went straight to the broken tree.

The Ice Girl said hello to Lin Bing and flew up. The formation had already been completely destroyed by the heavenly thunder, and the flight was no longer restricted. Lin Bing only had the strength of an earth immortal at this time, and he didn't have much combat experience, so he was not suitable for entering the tree to chase down the armor.

Flying was much faster than on land, and there were no Yin Beasts in this mountain forest, but he was too far away from the original position of the big tree, and the others entered the giant tree one after another, and he and the Ice Maiden were still flying, and after half an hour, they arrived before the broken tree. However, this is also because the two of them are injured now, and they can only heal at the same time, and their speed is limited.

"What a big tree!" Wood Lin and the Ice Maiden stood on the edge of the broken tree, and there were clouds and mist below, this giant tree was really too tall.

"It's empty!" The giant tree was now empty of its shell.

At this moment, two blue ice cubes appeared in front of the two of them.

"It's its breath, and when you get close to that dragon soul, it emits light. The old man's voice from the top of the mountain was weak. "The inside of your jade pendant has been changed by me, you can transmit the sound to each other, I can also know, you must transmit it as soon as you find it!"

"Yes, Teacher, we will complete the mission!" the Ice Girl took the ice cube and bowed, and Mu Lin bowed as well.

"Be careful, you know, this is a real dangerous place!"

"Teacher, I know!" said the Ice Girl.

Mu Lin and the Ice Maiden jumped down together, the space in this giant tree was wide, but it was pitch black, the light seemed to be absorbed, and it was still raining heavily in the sky at this time, so it was even darker here.

The two descended for several kilometers before reaching the bottom.

"Wow, this is a root, it's an underground cavern, like a world!" the wood forest illuminated the root with the light of the fire. Kai Tu used the heavenly thunder to bless the essence of his whole body on the dragon soul, and the original roots were already empty. The roots of the tree were about the same size as its upper body, it was longitudinal, it was horizontal, and the whole jungle was covered by its roots.

"It's no wonder that its rattan can be found all over the forest, because its roots are so huge. Mu Lin sighed.

"How do we find it? It's so big, and there are so many forks in the road!" asked the Ice Maiden.

"We are not as familiar as Armor Tu, if we use ordinary methods, of course it is like looking for a needle in a haystack. But even though it has a well-developed root system, think about it, if you were seriously injured, where would you go?"

"Find a safe place to heal!"

"Yes! Not only must it be safe, but it must also be suitable for its own recovery! Its power is cold and domineering, this is its root, we can find it when we find the place where the cold qi is the heaviest!"

"Oh!

"Let's go! This ice cube is also useful! It's close, it will guide us, let's just find the best cultivation treasure here first." ”

The two of them acted together, so it was more certain, no one knew how much strength the armor had left, but it hid for the first time, which means that it is now almost equivalent to a heavenly immortal, and it is afraid of being besieged, so it hid.

At this time, deep underground, at the bottom of the root of the giant tree, there was a black figure.

In front of it was a halberd, slightly longer than it was at this point, covered with cold air.

"These garbage that don't know whether to live or die, after I recover from my injuries, will all die!"

The dragon soul absorbed the cold qi above the halberd, and thought in his heart how to kill the wood forest.

Sometimes, you feel like time flies slowly, but sometimes, it's fast. Mu Lin and the Ice Girl searched for more than two days, but they found nothing, and Mu Lin was even more anxious. Although I don't care about it on the surface, I just don't want to affect the Ice Girl.

"Are you quite calm, aren't you afraid of this kind of danger?" Mu Lin asked in surprise as he looked at the ice girl who was very calm.

"What's wrong? Am I going to cry?"

"What a weird girl!"

"The exercises I practice are also considered ice attributes, and I have a way to find out where the cold qi is strong. The Ice Girl said suddenly.

"Then use it well!"

"But there is a disadvantage of this exercise, I will be unconscious, and the larger the place I explore, the longer I will be unconscious. It's so big here, I don't know how long I'll be unconscious, you have to protect me, can you?" said the ice girl with a somewhat abnormal face.

"Yes, I will definitely protect you! If it is dangerous, I will fall first!" Mu Lin had already felt the deep of his eyebrows, the breath of heavenly death, and his heart was full of dark clouds. He knew for himself that if this heavenly punishment was to fall, he would not be spared. Because his Heavenly Death Body has another name, that is, the Heavenly Punishment Body, the innate body that has been punished by the Heavens. Once he descends, the danger he faces is not a simple one plus one, but an internal and external enemy, and ten deaths.

So even though she knew that Ice Girl might pay the price, she had to accept this help.

"I'll make it up to you!" Mu Lin said secretly in his heart.
