It is June in the world, and the red sun is scorching.

On the island of the palace, the plum mountain in the west is cold, and the plum blossoms are cold, standing proudly in the wind.

Meishan is close to the sea, the cliff shore is not high, close to the foot of the sea, there is a platform, only a zhang from the water surface.

On the platform, there is a vast bamboo house, a verdant bamboo house, and the plum blossoms in full bloom, standing side by side in the wind, and then there is a boundless blue sea as a big background, living here is tantamount to living in a picture.

In front of the bamboo house, there is a flat land, which is not only extremely flat, but also black.

An old man in rough clothes and messy hair was squatting on the flat black ground, fiddling with his chips.

His calculations are long and segmental, round and square, and it seems that different shapes represent different numbers and symbols.

At first, the old man was very fast, but later, it became slower and slower.

The huge calculation chip occupies almost the entire three-zhang square black land.

Finally, the old man held a white chess piece in his hand and did not move for a while.

At this stop, it was half an hour, and the old man's eyes were staring at the black ground, and his gaze went from converging to hollow.

It seems to be out of the world, and the soul is out of body.

Suddenly, in the calculation box outside the black ground, a white chess piece jumped up in the air and was placed in a position on the black ground accurately.

The old man was frightened, woke up, and looked at the calculation chip again, suddenly, snapped, slapped his thigh, excited like a child, jumped and jumped, and shouted "Providence!" in his mouth.

Immediately, the old man came to his senses and understood that all this was of course not providence, but that someone was coming, and when he turned his head, he saw a bearded young man in a green shirt, standing in the distance, looking at him with a smile.

The bearded young man's face was extremely unfamiliar, and his temperament was very different, and he had never seen it before.

"I don't know if Your Excellency is from the Holy Clan, or if you are from the Taiqing Sect, Your Excellency's arithmetic talent is amazing. ”

The old man hugged his fists.

The bearded young man smiled, "Seniors, but you can't even recognize the juniors?"

As he spoke, Xu Yi changed his face and became Wang Qianqiu.

In the past 20 years, he has cultivated to a great progress, and his temperament has changed drastically, even if he has become Wang Qianqiu at this moment, the old man has been stunned for a long time and has never made a sound.

Suddenly, a wine jar flew towards the old man, the old man caught it, and then he opened the cover, smelled the wine, his face changed drastically, and he lost his voice, "I know, I know...... You scourge, you can't die, you can't die......"

Xu Yi had already sacrificed the boundary barrier bead, and although the old man was out of shape, he was not afraid of being noticed by outsiders.

This old man is naturally Elder Bai, and the wine jar that Xu Yi gave away earlier was the wine he offered to pat Elder Bai when he first met him.

Now that his temperament has changed greatly, although his face is Wang Qianqiu, Elder Bai is cautious by nature, where will he be gullible.

When he saw this jar of wine, he naturally confirmed Xu Yi's identity.

Xu Yi grabbed Elder Bai's violently trembling hand, and only then did he notice that Elder Bai had aged a lot.

In the past, in order to help Elder Bai regain his vitality, he did not hesitate to use a large number of treasures such as the Golden Soul Fruit.

Unexpectedly, twenty years have passed, and Elder Bai is so old that people dare not look at it carefully.

Elder Bai noticed the change in Xu Yi's expression, waved his hand and said, "The world has changed drastically, and my Donghua Immortal Gate can't be safe, the old man's cultivation is completely wasted, and he can't contribute to the Immortal Gate, but he can still be wise, and after twenty years of hard work, he finally protects my Donghua Immortal Gate's majesty, it's worth it!"

Elder Bai said vaguely, but Xu Yi understood.

In the past twenty years, Elder Bai may have contributed a lot of wonderful exercises to the Donghua Immortal Sect.

At least the three-five-seven swords, Xu Yi saw the Zifu Mansion Monarch of Donghua Xianmen back then.

This exercise is not taught by Elder Bai, who else can it be.

"By the way, don't patronize the old days, help the old man first, and solve this problem. I'm getting old, I'm really lacking in energy, it's been almost a month, and I still haven't figured out this high-level multiplier. ”

Elder Bai grabbed Xu Yi and pulled it towards the black ground.

Xu Yi knew his temperament, if he didn't solve this problem, this old man would not calm down and listen to him.

When he saw Elder Bai fiddling with the calculations, Xu Yi had already read all the questions, and he already had a plan in his heart.

But I saw that he had taken a calculation, divided five by two, and the fiddling ended.

Elder Bai stared at the calculation chips on the black ground for a long time, and suddenly, he took out an audio bead and photocopied all the calculation chips on the ground.

"I haven't seen you for twenty years, your numeracy is so strong, you have seen the way of heaven, it's good, it's really good. ”

Elder Bai was amazed again and again, both relieved and excited.

Fortunately, Xu Yi did not forget his words and never lost his mathematical studies.

What is exciting is that Xu Yi's current level of mathematics is so high that he can't look up, with this guy here, his future research will definitely be smooth.

Xu Yi pulled Elder Bai and sat under the old tree in front of the bamboo house, setting up two wine jars and a pile of cooked meat, "Talk about numbers, we have time, senior, do you know why my cave house was destroyed, and where did my maid go?"

Xu Yi returned to Donghua Xianmen, and he didn't find this place directly.

He was the first to return to his cave mansion, and when he left, he set up a ban and left Yan Zi with enough cultivation resources and living materials.

He believed that even if he left for twenty years, Yan Zi would definitely wait for him in the cave.

But when he sneaked back to the island, his divine thoughts were released, where was the shadow of Yan Zi, and even the cave was razed to the ground, there were no people on the island, but there were many spirit beasts.

It seems that his cave has been converted into a beast pen and pasture.

After that, he went to the Gongfa Building again, but he didn't find any trace of Elder Bai, and after several twists and turns, he found Elder Bai here.

Elder Bai picked up the wine jar and poured a sip, "Over the years, the old man has only been busy studying the exercises, counting the ways, and many things, but he doesn't know it clearly. ”

"Now, the Gongfa Building has also changed to someone at the helm, and the old man is basically waiting to kick his legs and close his eyes. As for your envoy girl, I've heard of it, and the head coach values it very much, and I have taught it myself, but I don't know what happened later. ”

Xu Yi secretly praised Zhu Zhangjiao for keeping his promise.

At the beginning, when he entered the East China Sea Demon Domain, he was about to find the land of fire spirits and condense the Tianyuan seed.

Zhu Zhangjiao once pretended to be a fortune teller and intercepted him, but he saw through it.

After some exchanges, Zhu Zhangjiao promised that as long as Xu Yi lived up to the Donghua Immortal Gate, he would do his best to maintain it, and promised to take care of Yan Zi.

Xu Yi didn't expect that the Zhuzhang Church would teach Yan Zi in person.

This favor is owed a lot.

After getting Yan Zi's news, Xu Yi's heart was relieved.

grabbed a deer leg, took a bite, and said, "Could it be that my cave mansion, or after Yan Zi was gone, the sect took it back and turned it into a ranch?"

Elder Bai's eyes flickered, but he didn't answer.

Xu Yi's heart was racing, and he said with a smile, "I know, it's my opponents who did it, I haven't returned for 20 years, I don't know whether I'm alive or dead, I think Wang is dead, I'm afraid there are not a few, I can't beat me, it's really unseemly to do these disgusting things to vent my anger, but I don't know who can be cheeky and do this." ”
