The huge sigil continued to stretch downward, until it reached two thousand meters below the ground, and still did not find anything useful.

"Not yet?" Yang Tian frowned, pondering that what he was looking for might not be here.

Yang Tian didn't give up, and was ready to extend another three thousand meters to take a look.

However, just as Yang Tian was extending two thousand meters again, an ancient cave was suddenly discovered.

This ancient cave can withstand such pressure without collapsing, which shows the extraordinary nature of this ancient cave.

"This material!" Seeing the material of this ancient cave, Yang Tian was immediately shocked.

These materials are celestial crystals, which have long been absent on Earth, and are only available on some ancient stars.

Yang Tian opened his eyes in an instant, withdrew the talisman, and turned his head to look at the crowd: "You wait for me first, I'll go down and have a look!"

"Hmm!" Lin Xiaoyue and the others nodded.

Yang Tian used his escape technique, and soon disappeared into the ground, heading straight for the ancient cave.

Entering the ancient cave, Yang Tian's divine consciousness dispersed, and he found that his divine consciousness here was completely useless.

Even if these ancient things are a long time ago, the power contained in them is still mysterious, and according to Yang Tian's estimation, this place may be something left by immortals.

The surrounding walls were covered with runes, these runes were very ancient, but Yang Tian was well-informed and had seen these things, but there were also those that Yang Tian had not seen.

There was no breath of life here, Yang Tian walked and moved, the speed was very fast, he was not sure how deep it was, he didn't know how long it would take, so he could only shorten the time as much as possible.

Ten minutes later, Yang Tian found that a huge space appeared in front of him, and he suddenly stepped a little and rushed towards that side.

It presents a huge circular square surrounded by four ancient caves that lead to four directions.

And the circular square in the center is a huge formation.

"Starry Sky Teleportation Array!" Yang Tian's gaze fell on the Starry Sky Teleportation Array, where the aura was thin, and the Starry Sky Teleportation Array could no longer be activated again.

In a corner not far away, Yang Tian saw a box made of extraterrestrial meteoric iron, with runes engraved on it, and a mark of yin and yang runes.

"This mark...... Seeing this mark, Yang Tian's eyes suddenly lit up, and then he reached out into a claw and grabbed the box directly in his hand.

Yang Tian knew very well that the Heavenly Machine Gate in the secret realm was this yin and yang symbol.

Yang Tian opened the box, and Yang Tian saw what he wanted the most.

"The fifth key! haha...... Finally found the last key!" Yang Tian was very happy and immediately put the key away.

Inside the box was a letter, sealed with runes.

Yang Tian opened it and saw that there were some exercises recorded on it, all of which were from the Tianji Gate, and there was also the secret of the hundred-step flying sword, and behind it were some introductions to the master.

There is no doubt that this is what Guiguzi Nie Feng left, and it is written that he has used the starry sky teleportation array to go to another planet, exhausting the last trace of energy on the starry sky teleportation array.

After reading the letter, Yang Tian put the letter inside untouched, and used the seal to seal it.

Yang Tian can't look down on the exercises of this heavenly machine gate at all, it's useless to ask for it, if one day someone who is destined to see it, you can practice according to the above exercises, but you can become a strong person.

However, from Yang Tian's point of view, if the thing is placed here, basically no one will find this thing in the future.

Yang Tian turned his head and carefully looked at this starry sky teleportation array, the runes on it were very ancient, as if they still contained a very deep magical power.

"It seems that this Starry Sky Teleportation Array is probably a passage connecting to the Immortal Realm!" Yang Tian took a deep look at the box, shook his head and said: "Guiguzi, Guiguzi, you have gone to the Immortal Realm, there are many strong people, you are just a weak creature at the level of a primordial infant, it is completely up to luck to be alive!"

It's just that how powerful this starry sky teleportation array is, the specific Yang Tian is not clear, if there is no talisman formation hidden in it, I am afraid that with the body of Guiguzi Yuan Infant, it will not be able to withstand the impact of space-time turbulence at all.

Yang Tian didn't delay any longer, rushed out directly, and soon arrived outside.

"Xianggong, how is it?" Mei Yuyan asked first.

Yang Tian looked at the group of people and smiled slightly, stretched out his hand, and five keys stood in the air.

"It's all together!" Mei Yuyan and Mei Niang were suddenly overjoyed.

"Hmm!" Yang Tian nodded.

"Okay, let's go!" Yang Tian put away the key, hugged Yang Lin, and said with a smile: "Xiaolin, I'll take you to another world, okay?"

"Another world?" Yang Lin looked at Yang Tian curiously: "Dad, what is another world?"

"It's where Dad has been going in the past few years, do you want to go?" Yang Tian asked.

Yang Lin thought for a while and said, "I want to be with my father, mother, and grandparents!"

"Okay, let's go now!" Yang Tian said as he looked at Yan Lingjiao and the others.

"Hmm!" Yan Lingjiao and the others nodded.

Yang Tian summoned the Soldier Demon Divine Sword, and the group of people stood between the Soldier Demon Divine Sword, and the speed was extremely fast towards the Bermuda Delta.

"Dad, I want to say goodbye to Teacher Liu, okay?" Yang Lin looked at Yang Tian with expectant eyes.

Yang Tian thought about it, felt that it was better to meet his son's wish, nodded and said, "Okay, let's go!"

As soon as Yang Tian's mind moved, the Soldier Demon Divine Sword instantly turned around, but he returned to Jiangling City in an instant.

Liu Xin and Wang Yongwen are in the kindergarten at the moment, and there are three policemen inside, who are asking them about something.

"It seems that the two of them are in a bit of trouble!" Yang Tian and the others instantly appeared in the kindergarten, immediately attracting the attention of those children.

"Wow...... Brother Lin!" Seeing Yang Lin, those children immediately ran over, and one of the little girls with pigtails shouted the most affectionately.

"Hee-hee...... Qingqing!" The little guy beckoned to the little girl, and then his eyes fell on Liu Xin.

Liu Xin and Wang Yongwen in the house were shocked when they saw Yang Tian and Yang Lin and others coming.

"Xiao Xin, that is the immortal who saved us!" Wang Yongwen said with great joy.

"It's really Xiaolin's father!" Liu Xin and Wang Yongwen hurriedly walked out, and the three police officers looked over and were shocked when they saw that it was Yang Tian.

"Senior Yang!" The leading police officer walked over and was overjoyed when he saw Yang Tian.

Three years ago, Yang Tian's legend was also very clear to them, but three years later, they didn't expect Yang Tian, who had disappeared, to come back.

Yang Tian's eyes turned to the three of them, and found that two of them were still acquaintances, but he didn't see Zhao Xue, so he immediately smiled and said, "What's the matter, Officer Zhao resigned?"

"Senior Yang, don't you know?" Liu Dong looked at Yang Tian in some surprise.

"What's the matter?" Yang Tian was a little puzzled.

"Captain Zhao is getting married, just today. Zhang Chen said.

"Then why didn't you go to your captain's wedding?" Yang Tian was a little puzzled.

"The captain has resigned a month ago, and now I am the captain, as for participating in the captain's wedding, we are not qualified to participate!" Liu Dong sighed helplessly.

"What's going on?" Yang Tian was a little puzzled.

"Captain Zhao's husband is from the Long family, Senior Yang, you should know what the Long family means!" Zhang Chen said.

"Oh!" Yang Tian nodded.

"Senior Yang, if you can, I hope you can rescue the captain!" Liu Dong plucked up his courage at this time and said.

Hearing this, Yang Tian frowned slightly and asked, "Isn't Zhao Xue voluntary?"

"Senior Yang, the person Captain Zhao has always liked is you, and you have no feelings for that person from the Long family at all!" Liu Dong said.

"Dad, Aunt Zhao Xue often buys good things for me to eat!" Yang Lin said at this time.

Yang Tian took a deep breath and didn't know what to do for a while.

Yan Lingjiao and Yang Niancheng didn't speak, and it was not good for the two of them to give advice on this kind of thing.

Lin Xiaoyue opened her mouth and said: "When you are away, Zhao Xue will always come over every once in a while, no wonder I haven't seen her for a while!"

"Xianggong, just do what you have to do, anyway, there are already so many sisters!" Mei Yuyan looked like she couldn't do anything about it.

Mei Niang didn't have any opinion on polygamy, and said mischievously: "Childe, one more sister is more fun." ”
