Lin Yichen didn't leave, but sat down cross-legged on the spot.

Since being frozen by Li Yan and discovering the powerful effect of opening up the Yuan Mansion with hot and cold stimulation, he has been thinking all day long about how to continuously carry out hot and cold stimulation, so as to open up the Yuan Mansion as soon as possible and completely advance to the first level of the Tibetan Spirit Realm.

At this moment, feeling the cold air rushing to his face, he suddenly paid attention.

These yin and cold qi are also yuan forces, as long as these yuan forces are introduced into the body, and the yang yuan power in the yuan veins circulates into the yuan mansion, you can carry out hot and cold excitation.

"You're not leaving?" Seeing Lin Yichen sitting down, Li Yan asked coldly.

Lin Yichen looked at Li Yan who turned his head and smiled, "I want to cultivate here for a while." ”

"Boom!"

Li Yan stopped talking and directly took out his sword.

Lin Yichen was stunned for a moment, and hurriedly said: "I'm cultivating here, and it won't get in your way, you won't let it!"

But seeing that Li Yan's face was still cold, he didn't say a word, and he took the sword directly towards him, floating over like a beautiful female ghost. Lin Yichen was helpless, and was about to get up and leave, but Li Yan directly passed him and drifted into the distance.

Lin Yichen was relieved, it turned out that Li Yan was not coming at him.

Turning his head to track Li Yan's back, he saw this ice beauty floating straight to the edge of the square thousands of kilometers away, and then, using the sword as a pen, wrote and drew on the ground.

Curious, Lin Yichen got up and ran over to look, only to see some strange lines carved on the ground.

"What are you doing here?"

"Set up!"

"What are you doing?" Lin Yichen looked at Li Yan, who was busy with his head down, but he didn't understand why the latter wanted to set up a formation here in Yinjing, if he wanted to resist demon beasts, the effect of setting up a formation on the city wall was better than here!

"Catch the Yin Xuanlu!"

Li Yan's answer was unexpected, she set up the formation not to resist the demon beasts, but to capture the legendary "Yin Xuanlu".

A glimmer of light flashed in Lin Yichen's eyes, remembering that Li Yan suddenly appeared in the team rushing to the aid of Qingyun Town, and asked Lin An if there was anything special in Qingyun Town, and then confidently set up a formation here, obviously everything had been planned.

"So you had a premeditated plan!"

Lin Yichen smiled, he didn't expect that Li Yan, who had always been cold and didn't seem to be interested in anything, would plan one thing like this.

Li Yan stopped the movement in his hand, looked up at Lin Yichen, his dark black eyes were cold and bright, and said coldly: "If you don't practice, don't get in the way here!"

"Hey, hey, I'm cultivating!"

Lin Yichen grinned, hurriedly ran back to the place where he was originally sitting cross-legged, and began to cultivate.

He first mobilized the power of the Yang Yuan in his body, so that half of the twenty-four Yuan Veins that had been opened were vacated, and then used this half of the Yuan Vein to attract Yin and Cold spiritual power into his body.

Half of Lin Yichen's body suddenly formed a layer of frost, which made him shiver uncontrollably.

He could clearly feel that the cold aura emanating from the Yin Well was even colder than the ice spirit power that Li Yan had frozen him before.

Yin and cold Yuan Li entered the Yuan Mansion, and the Yuan Mansion suddenly became frosty.

"The power of Yang Yuan is dispatched!"

Afterwards, Lin Yichen urged the fiery Yang Yuan power stored in the other half of the Yuan veins to rush into the frozen Yuan Mansion and carry out hot and cold agitation.

"Crackling, crackling......"

In the Yuan Mansion, there seemed to be a series of slight popping sounds, as if a thin layer of skin was falling off, and then a smile was in the power of Yang Yuan.

After a while, the Yuan Mansion seemed to have grown a little bigger.

Lin Yichen was overjoyed and immediately prepared for the next round of hot and cold excitement.

............

And at this time, a hundred miles away from Qingyun Town, a group of centaurs happened to encounter a defeated demon beast, and a fierce battle broke out.

Fortunately, the demon beasts are fleeing and have no intention of fighting, otherwise this group of people is likely to be wiped out.

However, even if the demon beast was just passing by, this group of people also suffered heavy casualties, a group of nearly twenty people, more than a dozen dead and wounded, and only three men and one woman were left.

"Horse-stepping! Where are there so many demon beasts!"

Among the three men, a sixteen or seventeen-year-old boy scolded and raised a knife to slash the corpse of a demon beast to vent the anger in his heart.

This young man is the young master of the Tiger Gang who pursued Lin Yichen and his party.

"Young Gang Master, let's go back! Demon beasts are rampant here, and it's very dangerous!" a big man persuaded.

"No!" Tiger Tu glared and roared, "Go back like this, then these people, won't they die in vain!

"However, I'm afraid these few people are not the opponents of those people from the Heavenly Wind Academy!" the big man hesitated, his face a little embarrassed.

Hu Tu turned his head to stare at the big man, and asked, "Hongwei, are you afraid? If you are afraid, just go back by yourself! It is enough for me to go with Lin Hai and Jingjing!"

"No, I'm not afraid!"

The big man hurriedly shook his head, he accompanied the tiger to slaughter out, if he went back, the helper would definitely not let him go.

"I'm just worried about the safety of the young gang leader!"

"Hmph!" Hu Tu snorted coldly, his face unhappy and unwilling, "We encountered demon beasts, do you think those people from Tianfeng Academy will be better?"

"The young master is right!" the plump woman threw a wink and said coquettishly, "The people of the Tianfeng Academy must be worse than us!

"It's still a beauty that can talk!" Hu Tu raised his eyebrows at the plump woman, his mood was much better, and he smiled, "Keep going!"

A group of four people, a few hours later, came to the hillside where Lin Yichen and the others had arrived.

Qingyun Town appeared in their sight.

"It's here!" Hu Tu looked at Qingyun Town from afar, his raised eyebrows furrowed slightly, "The people of Tianfeng Academy, the destination should be here!"

"Young Gang Master, are we going to enter the town now?" the big man asked Hu Tu in a low voice, for fear that the young gang leader would be more lively.

"No!" Hu Tu waved his hand and said in a matter-of-fact manner, "You go into the town to investigate, and when you come back, we will make plans!"

Hu Hongwei took the order and left, pretending to be a passing warrior, entered Qingyun Town to investigate, learned some information, and then returned and reported the situation to Hutu.

"Since the demon beasts will still attack, then we are not in a hurry!" Although Hu Tu was young, he had a lot of ghost ideas, and he said slyly, "Let's go into the city, find a place to hide, and wait for the opportunity when the demon beasts attack!"

"The young gang leader is really wise!"

Listening to Hu Tu's decision, Hongwei, Lin Hai and Jingjing, two men and a woman, slapped their assemblies in unison.

The four of them followed into Qingyun Town, and did not attract too much attention from the martial artists of Qingyun Town, who were busy, they avoided people and found a deserted courtyard where no one was there to hide.

At night, when the four of them were complacent, the door was suddenly kicked open.

"Who?"

Hu Tu, Jingjing, Hongwei and Lin Hai were eating, and when they saw someone breaking in, they all bounced up from their chairs and went to get their weapons as soon as they could.

However, before they could take out their weapons.

The sword, already up to their necks.

They were slow, and the four of them were stunned for a moment, judging from the speed alone, the people who came were all top masters, and they were not able to deal with them.
