The days passed as always, and three months passed in the blink of an eye.

During this period, in addition to taking a task to go to the Jiuheng Forest to collect Banyan Valley Fruit in the mission hall, he either slept and practiced, or at Xiaomeng's strong request, he went to the teahouse and the hotel to have a good time.

On this day, when Han Zi returned to her residence from the teahouse with Xiaomeng in her arms, she found a note in the crack of the door, Han Zi took it out and opened it to take a look, it turned out to be a letter written by Li Zhen to her, the content was to meet in the Fenglai teahouse after noon tomorrow, and there was an urgent matter to discuss.

Although the way of transmitting information between monks is mainly through the transmission of musical notes, whether it is family members or acquaintances, they will reserve each other's aura.

The transmission note is based on the monk's input of the other party's aura and breath, so as to form a search for the person who needs to be found, and Han Zi and Li Zhen have only had a one-sided acquaintance, so it is impossible to reserve the aura breath for each other.

For Li Zhen, Han Zi still has a good impression of him, Han Zi saw a trace of tenacity from his shrewd eyes when he saw him for the first time, although he lived at the bottom of the immortal cultivation world, he never gave up the yearning for the immortal path in his heart.

Han Zi opened the courtyard door, returned to the room, and gently put Xiaomeng, who was asleep in his arms, on the bed.

Sitting on the chair seat next to the bed, Han Zi said a word silently in his heart, only to see the yellow ring on the ring finger of his right hand suddenly shine brightly, and six gray-black stones appeared on the table.

These stones were occasionally found by Han Zi in the Jiuheng Forest, when Han Zi found this kind of stone, which was very similar to the uranium ore he had seen when he was on Earth, so Han Zi collected a lot of them and stored them in the Yellow Ring.

Picking up a gray-black stone, Han Ziyun had a spiritual aura in his eyes, took out a gray-black stone with his hand, and observed it carefully.

Under the observation of the spiritual eye, Han Zi found that the inside of the stone was filled with a radioactive substance, and compared this stone with uranium stone in his mind, and found that the shiny surface of this stone was like asphalt, and after observing Han Zi, he affirmed in his heart that this was one of the uranium ores, asphalt uranium ore.

After confirming that it was uranium ore, Han Zi was very pleasantly surprised: "It seems that my luck is really good, such a scarce uranium ore resource on the earth has unintentionally allowed me to get a lot." ”

Han Zi used her divine sense to carefully count the amount of uranium ore in the Yellow Ring, and after the counting, she cheered in her heart.

After counting, Han Zi carefully estimated that if he refined ten percent of the ore, he could get about 1,000 kilograms of uranium.

If it is refined to 90 percent, which is often referred to as uranium-235, she can refine 100 kilograms of uranium-235.

Uranium-235 is a radioactive isotope of uranium-235 that will be excited when the neutron number in the uranium element reaches 143, and fission isotope 92 will be formed when the phase number reaches 263, which is mainly used as a nuclear and one of the main raw materials for the manufacture of nuclear weapons.

Uranium became a fissile weapon with a huge radioactivity after the phase 263 atoms.

Han Zi learned from the Immortal Cultivation Realm's diary that the current energy emitted by the magic weapon of the Immortal Cultivation Realm's high-level Yuanying Late Peak Great Cultivator was able to destroy an area of five hundred kilometers.

If you make a simple comparison with atomic weapons, the energy generated by the atomic weapon only needs to be filled with three kilograms of uranium-235 can reach five million tons of high-explosive ** energy, which is completely comparable to the strength of the peak monk in the late Yuan Infant period.

Thinking of this, Han Zi couldn't help himself with excitement, if he could successfully refine uranium-235, he would have a powerful life-saving trump card, and he would also have his own foothold in this black and black immortal cultivation world.

Just after noon the next day, Han Zi came to the Fenglai Teahouse, entered the teahouse, and found that Li Zhen and a little girl about ten years old were already waiting for her.

When Li Zhen saw Han Zi coming, he immediately got up to greet him and shouted, "Miss Zhao!." ”

Han Zi claimed that his surname was Zhao, and the surname Zhao was also the family name of Han Zi's mother.

"I'm sorry Brother Li, I'm late!" Han Zi said slightly apologetically after being invited to a seat by Li Zhen.

"It's okay, we've just arrived, too"

Li Zhen waved his hand and finished speaking, then pointed to the girl next to him and introduced, "Miss Zhao, this is the sister Li Ying." ”

"Hello. ”

Han Zi smiled and nodded hello to Li Ying.

"Hello, Sister Zhao," Li Ying replied with a smile.

At this time, the teahouse Xiaoer served the tea and snacks, and Li Zhen poured a cup of spiritual tea for Han Zi and Li Ying.

Han Zi took the spiritual tea handed by Li Zhen, thanked him and asked, "I don't know what happened to me, Little Brother Li?"

Li Zhen saw Han Zi asking himself, glanced at Li Ying, and saw Li Ying nodded.

"This time I am looking for Miss Zhao, my sister and I are actually for you to participate with our brothers and sisters, and the secret realm of the secret heart will be opened in three months"

Li Zhen explained seriously.

"Secret Realm?"

Han Zi was a little confused, and when she saw the circled portrait on Han Zi's face, Li Ying on the side immediately explained: "The secret realm of the secret realm is opened once every hundred years, and in three months it will be the opening date of this hundred-year period. ”

"Sister Li Ying, can you tell me about the secret realm of the secret heart. ”

Han Zi was very embarrassed that his knowledge of the Immortal Cultivation Realm was limited, and he thought to himself that his knowledge of the Immortal Cultivation Realm was really poor.

Li Ying could also see Han Zi's embarrassment, but she didn't despise Han Zi at all in her heart, but explained it to Han Zi very seriously, so that Li Zhen, who was left aside, was very injustice in her heart, why are girls so easy to get along with, and her eloquence is not bad.

"The Secret Realm of the Dark Heart is a time in ancient times, when the ancestor of a super great sect, when he was about to ascend to the immortal realm after breaking through the peak of the late Mahayana period, he failed to withstand the ninety-nine heavenly thunder descended from the Heavenly Dao, and was martyred by the thunder tribulation. ”

After Li Ying finished explaining seriously, Han Zi nodded clearly.

"Although there are abundant resources in the dark heart space, there are restrictions on cultivation, only monks in the Qi cultivation period are allowed to enter, and if other high-level monks forcibly enter, they will be repulsed by the space. ”

Li Ying explained again.

"I see!"

Han Zi nodded and said clearly.

"Sister, you can rest assured, the resources you get in the secret realm at that time, my brother and I will never let my sister suffer, then we will divide fifty-fifty, sister, you think about it." ”

Li Ying said in a kind tone.

What a shrewd little girl! Han Zi gave Li Ying a big thumbs up in her heart.

Looking at Li Yingshuangmu's kind shrewdness, Han Zi nodded seriously and agreed: "Okay, I promise to go to the secret realm with you, but I have a request." ”

"Sister, please speak. ”

Li Ying saw that Han Zi agreed. There was some joy in my heart.

"I ask that the resources we receive be divided into three parts, and I do not want to take advantage of your brothers and sisters. ”

Han Zi said to the brother and sister with a serious face.

After listening to Han Zi's words, looking at the serious expression on Han Zi's face, Li Ying and Li Zhen were stunned, and both of them thought at the same time: "What kind of request is this?"

"Sister, this..."

Li Ying said, not knowing how to go on.

At this time, Li Zhen suddenly spoke: "Sister, this is Miss Han's kindness, let's not live up to her kindness." ”

After listening to her brother's words, Li Ying nodded and said to Han Zi: "Just follow my sister's words." ”

Han Zi looked at the kind-hearted brother and sister, and sighed very much in her heart! The reason why she wanted to divide the resources obtained into three parts was that she thought that Li Zhen's brothers and sisters must have lived a very hard life, and it could be seen from Li Ying's precocious performance, but this is the case, the brother and sister are willing to share fifty-fifty with her, which can see the sincerity in the hearts of the two brothers and sisters.

"Miss Zhao, then we'll go back, and we'll get in touch in three months. ”

Li Zhen got up from his seat and hugged his fist at Han Zi.

Han Zi also replied with a woman's gift: "Well, okay, little brother Li." ”

"Sister, goodbye. ”

Before leaving, Li Ying warmly held Han Zi's hands and said goodbye to Han Zi sweetly.

Looking at Li Ying also made Han Zi miss Yuanyuan in his heart, and he didn't know how Yuanyuan's modernization in the mortal world was!

"Well, goodbye, sister. ”

Han Zi smiled and nodded in reply.

Before leaving, Han Zi and the brother and sister each left their aura and entered it into the transmission note so that they could contact.

Bidding farewell to Li Zhen's brother and sister, Han Zi returned home and saw that Xiaomeng was still asleep.

"Xiaomeng, what's wrong. ”

Han Zi looked at Xiao Meng, who was sleeping and screaming, and pouted.
