Infinite Upgrade Technique of the Heavens

Chen An walked out of the library and walked into the pavilion that was used to store the spiritual materials of heaven and earth.

"Who dares to trespass into the treasure pavilion of Wanshou Mountain?"

As soon as Chen An stepped into the treasure pavilion where the spiritual materials of heaven and earth were stored, a deep voice asked sternly.

"I am Chen An, the new disciple of Zhen Yuanzi Daxian. I wonder who you are?"

"Hey, young master. How did you come in? Are you looking for something?"

As soon as Chen An finished speaking, a flying sword with a human face appeared in front of Chen An and said to him with a smile.

"Hey, who are you?"

Chen An looked at the sword in front of him, his eyes widened instantly, and asked in disbelief.

The sword in front of him was golden, but the aura on it was somewhat similar to the Wanfa Pearl in Chen An's body. Chen An asked curiously.

"Hehe, young master. I am a congenital spiritual treasure golden sword. I developed spiritual intelligence by accident. Zhenyuan Daxian felt that the heaven had the virtue of loving life, so he did not erase my spiritual intelligence and brought me back to Wanshou Mountain. He asked me to guard the treasure pavilion to prevent any villains from breaking in."

The golden sword smiled and said to Chen An after hearing Chen An's question.

"Congenital spiritual treasure, then you are very powerful, why do you stay here all the time?"

After hearing the words of the congenital spiritual treasure golden sword, Chen An looked at the golden sword and asked curiously.

"Alas, my congenital nurturing is incomplete. Although I have developed spiritual intelligence, I can't practice. I can only accumulate the sword energy in my body bit by bit. Although I can reach the level of Golden Immortal every time I launch an attack, after using it, I will immediately fall back to a level that can be defeated by mortals, and accumulate sword energy again from the beginning."

After hearing Chen An's question, the golden sword looked at Chen An in frustration and spoke to Chen An.

"Oh, so that's how it is. I was thinking that if you were a congenital spiritual treasure with spiritual intelligence, you would be considered a congenital god-demon-level existence. How come you are still in the form of a sword?"

After hearing what Huang Jinjian said, Chen An suddenly realized and said to Huang Jinjian.

"Hey, young master, these are just trivial matters for me. What are you going to do in this treasure pavilion?"

Huang Jinjian was not angry when he heard what Chen An said. He just smiled and changed the subject, asking Chen An.

"Oh, I just finished reading in the library. My cultivation level has broken through. I want to get some spiritual fruits and spiritual materials to assist me in my cultivation. Huang Jinjian, do you have any recommendations?"

After hearing Huang Jinjian's question, Chen An smiled and said to Huang Jinjian.

"Young Master, I do have some stuff like this. Here are some of them. They are suitable for you to use when you practice. Although they are not of high quality, the spiritual power they contain is very rich and easy to absorb. You can take them and eat them, which can help you save a lot of time absorbing spiritual power."

After hearing Chen An's question, Huang Jinjian quickly selected hundreds of innate spiritual fruits from the treasure house and placed them in front of Chen An, smiling and saying to Chen An.

"If you eat so many innate spiritual fruits like this, will there be no more in the future?"

Chen An looked at the complicated fruits that Huang Jinjian had taken, and he was embarrassed to take them, so he said to Huang Jinjian awkwardly.

"Young master, you don't know this. These spiritual fruits are the fruits of the innate spiritual roots after nine generations. They are not precious at all. After you eat them, the innate spiritual roots will grow again. There are many of these innate spiritual roots planted in Wanshou Mountain, so you don't have to worry that there will be no more after you eat them."

After hearing Chen An's words, Huang Jinjian smiled and placed all the innate spiritual fruits in front of Chen An, and said to Chen An.

"Oh, so, then I know, thank you, Huang Jinjian."

Chang'an suddenly realized what Huang Jinjian said. He smiled and put all the fruits in front of him into his Qinglian Godhead. After saying goodbye to Huang Jinjian, he left the treasure pavilion and returned to his residence.

"You are worthy of being the ancestor of earthly immortals. I thought that Master only had the ginseng fruit as an innate spiritual root. According to Huang Jinjian, it is probably the innate spiritual root of a world."

Chen An took out an innate spiritual fruit, which looked a bit like a pear. After quickly swallowing the innate spiritual fruit, Chen An muttered and said.

But then, the spiritual power that burst out from the innate spiritual fruit left Chen An no time to think about other things. He immediately sat cross-legged and began to absorb the spiritual power of the innate spiritual fruit according to the records of the Earthly Immortal Treasure Book.

Chen An ate more than 20 innate spiritual fruits in a row, allowing his cultivation to quickly break through from the Spiritualization Stage to the Return to Void Stage.

After Chen An ate nearly 300 innate spiritual fruits, his cultivation successfully broke through to the Mahayana Stage.

After reaching the Mahayana Stage, Chen AnStill without stopping, he continued to eat all the remaining innate spiritual fruits.

With the spiritual power provided by these innate spiritual fruits, Chen An began to repeatedly temper his strength, allowing the spiritual power in his body to continuously condense and become a kind of true essence.

When Chen An's cultivation reached the limit, the heaven in the dark told Chen An. After seven days, Chen An can cross the tribulation, and after crossing the tribulation, he can officially become a human immortal.

After receiving the information from the heaven, Chen An did not dare to delay, and quickly came out of retreat and walked towards the treasure pavilion.

"Young master, are you coming out of retreat? From the looks of you, you are planning to cross the tribulation."

The golden sword in the treasure pavilion saw Chen An coming in, circled around Chen An, and said to Chen An with a smile.

"Yes, Golden Sword. I have tempered my cultivation many times and reached the ultimate level of the Mahayana period. I just received a message from the Heavenly Dao that I will pass the tribulation in seven days. I heard that the thunder tribulation is very terrifying. Can you help me think about which treasure can guarantee that I can pass the thunder tribulation smoothly?"

Chen An did not refute the words of Golden Sword, but asked Golden Sword with a smile.

"Oh, this really stumps me. All the disciples that Zhenyuan Daxian accepted before were accepted after becoming immortals. Before becoming immortals, there was only you. I really don't know which treasure to take from this treasure pavilion to help you pass the tribulation?"

After hearing Chen An's inquiry, Golden Sword flew around the entire treasure pavilion and said to Chen An embarrassedly.

"Ah, how could this be? Is there no treasure in the treasure pavilion that can help me pass the tribulation?"

After hearing the words of Golden Sword, Chen An suddenly widened his eyes and said to Golden Sword in disbelief.

"No, every treasure in the treasure pavilion can help you get through the immortal stage, but I don't know which one to choose."

Golden Sword immediately retorted after hearing Chen An's words.

"Okay, just help me choose a defensive treasure that can help me resist the immortal thunder tribulation."

After hearing what Golden Sword said, Chen An said to Golden Sword helplessly.

"Okay, then this one. The middle-grade innate spiritual treasure lightning shield."

After hearing what Chen An said, Golden Sword quickly took a semi-circular shield with a faint purple light from the shelf and said to Chen An.
