If I had known I wouldn't have saved you!

She smiled slightly and went outside again with the pills.

Seeing Gu Roushuang working so hard for his cultivation, Lin Shiyi was deeply moved. He looked down at the child in his arms and began to consider whether he wanted one too.

The child was extremely adorable. He was holding a pill and looking at it left and right. Then he put it in his mouth and started chewing it like candy beans. After eating the pill, his cultivation level also improved greatly.

Demon beasts are different from human cultivators. As long as there is enough spiritual energy in their bodies, their levels will naturally increase.

After returning the child to Si Yunjie, Lin Shiyi asked again, "By the way, where is your sister? Why didn't I see her when I came back this time?"

Hearing this, Si Yunlan's smile disappeared all of a sudden. She lowered her head slightly and said nothing.

Chen Yijun, who was standing by, was also a little sad. He hugged his wife and child in his arms, then sighed and said, "Her sister disappeared not long after you left..."

Lin Shiyi was startled and asked quickly, "Missing? What happened?"

Chen Yijun didn't know what to say, but Si Yunjie wiped her tears and said with some contradiction: "My sister's disappearance is also due to you..."

"Me?" Lin Shiyi was speechless.

Si Yunjie nodded and said, "Of course, this is only part of the reason. After you left, my sister was drunk all day long, and she was absent-minded in everything she did. Then one day, a group of mountain bandits suddenly appeared in Wanling Mountain. They specialized in hunting monsters and harming the creatures in the monster world. Because we signed a non-aggression agreement between humans and monsters, the king did not send troops rashly, but decided to find out whether someone was stirring up trouble. After my sister knew about this, she volunteered to go and investigate, but the king did not agree, so she quietly left and has not returned until now..."

"Later, I found a letter in her room. It turned out that... in addition to solving the problem of the bandits, more importantly, she wanted to go to Xuantian Continent to find you through the interface channel of Wanling Mountain..."

After hearing Si Yunjie's words, Lin Shiyi's heart was like surging waves and he couldn't calm down for a long time.

“Is it… really like this?”

He was a little distracted for a moment.

He just didn't want to waste a woman's best years, but he ended up ruining her life.

If Si Yunlan really went to Xuantian Continent, it is impossible that she did not see him. Since there has been no news of her for such a long time, she must have been killed by the bandits, or lost in the Sumeru Ghost Mist, or swallowed by the crack...

Either way, it is the outcome that Lin Shiyi does not want to see.

If he had taken Si Yunlan away at the beginning, the woman would not have ended up like this.

For a moment, he felt extremely guilty.

"It was me who killed her...it was me..."

Lin Shiyi muttered in despair, but scenes of the time when they went to the north to fill the rift flashed before his eyes.

He thought Si Yunlan's love for him was just a momentary impulse, but he didn't expect her to be so infatuated.

Seeing Lin Shiyi's lost look, Si Yunjie couldn't bear it. She wiped her tears and said, "Brother Lin, don't be too sad. Sister may be fine, but she just can't come back for the time being..."

Lin Shiyi knew that this was to comfort him. After so much time had passed, if he could have come back, he would have come back a long time ago. Most likely, he would not be able to come back...

He waved his hands weakly and said, "I have a great responsibility for your sister's affairs... Don't worry, whether she is still alive or not, I will find her."

After saying this, he left the hall alone.

Seeing that many cultivators were about to break through, Chen Yijun could only stay here and personally set up a barrier for them to prevent them from being disturbed.

For a moment, the hall was filled with mysterious light, the colorful lights were extremely dazzling, and the surrounding spiritual energy was filled with chaotic pressure from various cultivation levels.

Lin Shiyi returned to his room alone. He sat cross-legged on the bed, feeling the pure immortal power coming from the red threads.

As those who swallowed the pills improved their cultivation, the immortal power fed back to him became more and more. However, after the late Nascent Soul stage, the capacity of the Dantian became larger, and these immortal powers were still far from enough for him to advance to the Spirit Transformation stage.

But the gain is still quite obvious. If this medicine is really popularized and more people can eat it, then it is only a matter of time before he enters the Spirit Transformation Realm.

However, while practicing, Lin Shiyi was also concerned about Si Yunlan's affairs. He felt full of guilt towards this woman, and because of this incident, he was more determined to become stronger. If he did not enter the Spirit Transformation Realm as soon as possible, his companions might be harmed.

In the days that followed, he entrusted the matter of alchemy to Zhang Cai, and went to the alchemy room on time to provide essence and blood, and also instructed the dosage to be used in alchemy.

Of course Zhang Cai was very happy to do so, and he began to refine the elixir day and night. He named the elixir Qiankun Pill, and after it was refined, Chen Yijun sent people to distribute it throughout the Wan Yao Country.

Because the effect of the elixir is obvious to all, the number of monsters taking the elixir is increasing day by day. Through the connection of the Qiankun Pill, Lin Shiyi and they give back to each other and both benefit greatly.

In the blink of an eye, another three years have passed.

Lin Shiyi also cultivated to the peak of the late Nascent Soul stage and was almost on the verge of breaking through to the Spirit Transformation stage.

But he couldn't get in no matter what, as if there was a force suppressing him and preventing him from breaking through.

During this period, due to the improvement of his cultivation, Chu Qingyi had already refined the Heaven-supporting Instrument. Under the escort of many highly-cultivated cultivators, he safely placed the Heaven-supporting Instrument on the four edges of the Demon Spirit Realm. However, due to the existence of the Sky-viewing Mirror, the divine cultivators who came down from the sky would always be eliminated by many cultivators using a joint formation not long after they arrived.

With the help of Qiankun Pill, the demon spirit world is now a completely different place. High-level cultivators and eighth-level monsters are everywhere. They use human wave tactics to drag down the divine cultivators who have been sent down from the sky. Although many cultivators and monsters have died, they are willing to continue to fight because they are doing it to protect their homes.

The Divine Transformation cultivators always descend with the cultivation level of the late Nascent Soul stage, which gave Lin Shiyi some inspiration.

Is it true that in this realm, cultivators cannot break through the Divine Transformation Realm? Therefore, those great cultivators can only descend with the cultivation of the late Nascent Soul stage. This makes sense.

If Lin Shiyi wants to break through to the Spirit Transformation Realm, he must break through the boundary and leave.

If he used his current strength at the peak of the late Nascent Soul stage to attack with all his strength, it would not be difficult to break through the space, but if he left this world, what would his companions do? What should he do after breaking through the world? All of these were still confusing.

After thinking this through, he became a little hesitant.

Over the past three years, after reaching the peak of the late Nascent Soul stage, he had stored all of his excess immortal power using the secret method of Qiankun Gong. If he could reach the Spirit Transformation stage, these immortal powers would be able to help him improve his cultivation further, but it was unclear how much it could improve.

After I go up, can I fight against the Nightmare Demon?
