This cave is very huge and wide, with crisscrossing cave passages inside. Ye Li didn't know which passage the Nine-Colored Divine Bull had entered.
There is a very faint light in the cave, and there is some fine sand on the wall that can emit a faint light, which looks like powder of some luminous material.
No matter how good the monster's eyesight is, it still cannot see anything in the absolutely dark cave. The reason why this underground cave became the lair of the Nine-Colored Divine Bull is obviously related to the faint light inside it.
Many natural mineral materials have the ability to emit faint light. Under the faint light of this underground cave, even Ye Li can see things clearly.
After squatting on the ground and groping for a while, Ye Li quickly found traces on some relatively moist ground.
Among these traces, there are some hoof prints, which are obviously left by the Nine-Colored Divine Bull.
Ye Li groped his way carefully, following the traces on the ground, through a cave passage, and deep into the underground cave.
Soon, he heard a noise coming from not far away.
After carefully groping forward for a distance, a huge cave hall appeared in front of Ye Li. Ye Li took a look into the cave and saw four nine-colored divine bulls.
At this moment, two of the four nine-colored divine bulls were butting each other's horns, as if they were playing, while the other two were lying on the rocks nearby to rest.
“Ye Li, wait for the right moment to release us, and attack these four nine-colored divine bulls at the same time, without giving them any chance to self-destruct.
It is necessary to take one more Nine-Colored Spirit Crystal. The little bald boy said that he only needed three, which was probably a rough estimate.
If we bring back four, it might only be of greater help."
Tunri said to Ye Li.
Ye Li nodded upon hearing this, and then restrained all his aura, even closing his pores, so that not a single bit of aura leaked out of his body.
Ye Li carefully moved forward a distance, then lay on the ground like a cold stone.
He aimed at one of the nine-colored sacred bulls, and then transmitted a message to his dantian: "I will attack the nine-colored sacred bull in the middle, Senior Tunri will attack the one on the left, and Senior Yinhuo and Senior Binghuang will attack the two on the right respectively.
We must kill the four Nine-Colored Divine Bulls instantly and not let them explode!"
After hearing Ye Li's words, Tunri and the others nodded. After confirming the target of attack with each other, they waited quietly.
Once Ye Li launches an attack, they will attack at the same time and kill the other monsters separately.
Ye Li, who was crawling on the ground, took a deep breath and suddenly rushed forward like lightning.
The movement on his side instantly startled the four nine-colored divine bulls. This kind of monster was very vigilant. After confirming the possible threats around them, their first reaction was not to resist, but to prepare to escape to the cave passage at the back.
However, Ye Li had already prepared for such a situation. He instantly activated the power of the universe and changed the flow of time around him.
Looking at the Nine-Colored Divine Bulls that had stopped moving, Ye Li rushed towards them at the fastest speed. While the effect of the Universe Time Domain had not yet disappeared, he had already arrived not far from the four Nine-Colored Divine Bulls.
At the moment when the universe and time domain disappeared, Sun-Swallowing, Ice Emperor and Yin Fire Divine Puppet instantly left his body and rushed towards the other three nine-colored divine bulls separately.
A golden light flashed in Ye Li's hand, and the secret gold-casting method was activated. The nine-colored divine bull in front of him had no time to escape, and Ye Li rushed in front of it and slapped it on the head with one palm.
With a flash of golden light, an extremely sharp golden spiritual energy shot into the forehead of the Nine-Colored Divine Bull like a blade, and completely pierced through the Nine-Colored Divine Bull in an instant.
The crushing superiority in realm allowed Ye Li to kill the nine-colored divine bull in an instant.
The speed of Tunri was also astonishingly fast. A ray of yang fire power turned into a line of fire that spurted out of Tunri's nostrils and directly penetrated into the center of the eyebrows of the Nine-Colored Divine Bull.
The head of the Nine-Colored Divine Bull instantly caught fire, and its brain turned to ashes in an instant.
The heavy body fell to the ground with a dull thud.
The Nine-Colored Divine Bull in front of the Ice Emperor had just taken a step to escape when an icy force froze it in place. Then an ice knife cut through it, and the entire head of the Nine-Colored Divine Bull rolled off its neck, killing it instantly.
On the other hand, the Yin Fire Divine Puppet moved just as quickly. The Yin Fire in its hands turned into a flame mist and rushed directly into the mouth and nose of the Nine-Colored Divine Bull.
A flash of black air passed over the face of the Nine-Colored Divine Bull, and the power of Yin Fire instantly burned its body into a mummy.
In just a blink of an eye, the four nine-colored divine bulls died in front of Ye Li.
Seeing this situation, Ye Li finally breathed a sigh of relief and his face became a lot more relaxed.
"Ye Li, quickly take out the Nine-Colored Spirit Crystal, we will take it back immediately to rescue Little Baldy.
I’m afraid the situation will change over time, the sooner we go back the better!!!”
Tunri was worried about the Nine-Colored Peacock King and urged Ye Li to speak.
Ye Li nodded hurriedly after hearing this and said, "Senior Tunri, where is the Nine-Colored Spirit Crystal?"
Tun Ri said: "The Nine-Colored Spiritual Crystal is in the heart of the Nine-Colored Divine Bull. You can cut open their bodies and take out the Nine-Colored Spiritual Crystal."
Upon hearing this, Ye Li waved his hand and threw out his golden sword, which turned into a stream of light and split into four sword shadows.
In an instant, sword shadows were flying, and the bodies of the four nine-colored divine bulls were directly cut open, and their hearts were all split in half.
Ye Li took out four eyeball-sized nine-colored beads from their hearts one by one.
"Yes, these nine-colored beads are the nine-colored spirit crystals.
We have got the stuff, let's hurry back to the Monster Mountain Range!!!"
Tunri urged again.
Upon hearing this, Ye Li naturally did not delay at all. He turned around and rushed out of the cave.
After leaving the cave, Ye Li flew into the air and headed back towards the Monster Mountain Range.
He was very fast and it took him half a day to get back to the Monster Mountain Range.
Ye Li rushed back in just two days out of the three days given by the Nine-Colored Peacock King. At this time, the Nine-Colored Peacock King had not exploded due to the loss of control of his power, which made him feel relieved.
Ye Li landed in the middle of the Nine-Colored Sky Lake. The Nine-Colored Peacock King seemed to sense Ye Li's presence and opened his eyes with difficulty, saying, "Quick, put the Nine-Colored Spirit Crystal in my mouth!!!"
After saying that, it gently opened its mouth and aimed at Ye Li.
Ye Li did not dare to delay for a moment, and hurriedly took out four nine-colored spirit crystals, and then stuffed them into the mouth of the Nine-Colored Peacock King.
When the Nine-Colored Peacock King saw that Ye Li had four nine-colored spirit crystals in his hand, a look of joy appeared on his face. It seemed that having one more spirit crystal was indeed a good thing for him.
