One day later.

Sima Qing'er's condition finally stabilized, and Li Tianyi's heart, which had been hanging in suspense, was completely relieved. He felt dizzy and quickly held onto the mountain wall for support.

"Ding! Crimson Gold Treasure Chest* Modified, successfully opened, obtained: Supernova Nuclear Fusion Energy Cannon Research Data, Planet Destruction Laser Energy Cannon Research Data, Interstellar Forging Furnace Infinite Forging Factory Complete Set of Data."

"Ha, ha!" Li Tianyi was extremely excited. "With this data, we can create an interstellar team and no longer have to fear those alien scum who covet Earth!"

The more you look forward to the future, the more excited you become, and all your weariness vanishes.

It took several hours to return to normal.

At the same time, Sima Qing'er also woke up, weakly calling out, "Water, water!"

Li Tianyi helped her up and put the mineral water in her mouth.

"Cough, cough!"

"Slow down, no one's going to take it from you!"

Sima Qing'er rolled her eyes at him, "This is all your fault!"

Li Tianyi felt a chill run down his spine, and cold sweat poured down his back. "The situation was urgent at the time. If I hadn't done that, you would have died from the poison long ago!"

"Hmph!" Sima Qing'er pouted, her cheeks puffed out in anger, and muttered, "My first time was lost so carelessly, how annoying!"

Li Tianyi was in the wrong and remained silent.

Sima Qing'er grew angrier the more she thought about it and wanted to slap him a couple of times. But as soon as she exerted force, she felt a sharp pain all over her body and cried out in surprise.

"Don't move around, the remaining poison hasn't been completely eliminated!"

Sima Qing'er glared at him fiercely, then buried her head in the blanket...

Three days later, the outside world...

Jia Qingxue was anxiously searching outside the cave, calling out, "Brother Tian, ​​Brother Tian, ​​where are you?"

Leaning helplessly against the mountain wall, she was overwhelmed by a mix of negative emotions, including grievance and heartache, and tears streamed down her face uncontrollably.

Suddenly, a bright spot appeared on the left slope.

"What is this?" Jia Qingxue was terrified, gripping the laser gun tightly.

The bright spot suddenly grew larger, and two people rushed out from it.

They were moving too fast for Jia Qingxue to see their faces clearly before she pulled the trigger.

The gun was lifted up, and the laser shot into the sky.

Li Tianyi shouted, "Qingxue, it's me!"

Jia Qingxue threw away the laser gun and kept punching Li Tianyi with her little fists, yelling, "Who told you to leave? Who told you to leave!"

Sima Qing'er watched all this with a complicated expression.

Not long ago, he accidentally triggered a hidden mechanism while beating Li Tianyi, and was teleported out in a daze.

"Stop!" Li Tianyi grabbed her hand. "Qingxue, stop fooling around. We've been lingering here too long. I'm worried that the two deans might be in danger. We must get out as soon as possible!"

Jia Qingxue shuddered, suppressing her temper, and stared at Sima Qing'er, "Sister, did he torment you too?"

Sima Qing'er rolled her eyes and looked into the distance.

The three separated and continued searching for a way out...

Several hours later.

"We've searched the entire area, but found nothing!" Li Tianyi frowned slightly. "Let's recover our strength and then search the outer perimeter!"

The two women blushed immediately and walked in different directions.

Li Tianyi instantly understood and smiled faintly, "Don't sneak into bed later!"

"You...you're going to die!" Sima Qing'er said shyly.

"Ugh!" Jia Qingxue stomped her foot.

This is the middle of nowhere, and only Li Tianyi's spatial ring has a luxurious bed.

The two women were also tough; they didn't go over even though they were shivering from the cold.

Li Tianyi couldn't bear to watch any longer, so he rushed over, pressed Sima Qing'er's pressure points, and threw her onto the bed.

I covered her with the blanket and said, "Don't be afraid, sleep peacefully!"

Soon after, he carried Jia Qingxue over again, saying, "Go to sleep!"

Li Tianyi slept on the outermost side, and soft snoring could be heard...

Lop Nur, at the foot of a mountain.

Wei Zheng and Yu Feng were in a sorry state, panting heavily, and glancing into the distance every now and then.

He took out his water bottle, but there wasn't a drop of water in it. He smiled wryly, put it down, and leaned against the mountain wall to rest.

The two were so tired that they soon fell asleep.

Suddenly, a green dot the size of a mung bean appeared on the left diagonal.

The light grew brighter and brighter.

Wei Zheng suddenly woke up, grabbed the laser gun, and shouted, "Get up!"

"What's wrong?" Yu Feng asked, completely bewildered.

Sizzle, sizzle!

The green light spot gradually grew larger, eventually becoming an oval shape about two meters in diameter.

Three figures rushed out from inside.

"Don't shoot!" Li Tianyi shouted.

Wei Zheng and Yu Feng finally felt relieved and leaned against the mountain wall.

"Where did you go for those seven hours?"

Sima Qing'er and Jia Qingxue stared wide-eyed, their faces full of questions, "Shouldn't it be seven days?"

Li Tianyi frowned slightly and stroked his chin. "If my deduction is correct, we should have been in a special space for the past seven days, where time flows 24 times slower than outside!"

"Hiss!" Jia Qingxue was stunned for a moment, then overjoyed. "If we can master this technology, what is there to fear no matter how many alien scum come?"

Wei Zheng smiled wryly and shook his head, "This is beyond our research scope. Let's be more practical and finish the research projects we have on hand first!"

"The dean is right!" Yu Feng nudged Li Tianyi. "Quickly, take us back to the lab!"

"Alright!" Li Tian's eyes darted around quickly, and a smile appeared on his lips. "I'll take you to a more advanced and safer experimental base!"

"The Dafeng Mountain Experimental Base?" the crowd asked.

"Um!"

Li Tianyi summoned a transport vehicle, which carried several people and sped towards the edge of the no-man's-land...

Nine hours later.

"Everyone's exhausted after a long day. Let's rest for a few hours before continuing our journey!" Li Tianyi gazed at the horizon.

"Yes, everyone, take a break!"

After everyone rested, Li Tianyi became a sentry.

Before they knew it, they had arrived at the coldest time of the year in the wilderness, and even their internal energy was starting to give way, causing them to shiver from the cold.

Yu Feng and the others were awakened by the cold and rushed to the fire.

"It's so cold, so cold!"

Sitting by the fire, I didn't warm up; instead, I grew colder and colder.

My jaw was chattering, and snot was dripping uncontrollably from my nose.

Li Tianyi's expression turned solemn. He immediately set up a protective device to cover everyone, and the extreme cold instantly disappeared. He muttered to himself, "Could it be that there is a creature with extreme cold here?"

"You all stay inside the protective shield, I'm going to go outside and check!"

Be careful!

Li Tian nodded and went outside. An even colder feeling than before spread throughout his body, as if his blood was about to freeze.

After circulating internal energy, my body warmed up a bit.

My gaze shifted straight ahead, where there was a blue dot of light, constantly emitting mist.

"So it was you who was behind this!"

The Po Jun sword hummed as it unleashed a sharp, swift blade of light.

Swoosh! Boom!

Blue lights flashed rapidly, the fog thickened, the ground began to freeze, and the vegetation was frozen and burst.

The aura arrived extremely quickly, reaching us in an instant.

Li Tianyi frowned slightly, his face frosty, and focused all the power he could muster on Po Jun.

"The power of the sun!"

A fireball appeared, and the scorching wind and the extreme cold collided, causing continuous explosions.

Neither side wanted to give way, and the two sides were evenly matched.

As time went on, Li Tianyi could no longer hold on; cold sweat poured down his face, and his legs trembled slightly.

Another half minute passed, and large beads of sweat rolled down his face. His right arm trembled more and more violently, and even Po Jun could hardly hold it.

After gritting his teeth and persevering, he could no longer muster any strength, and Po Jun slipped from his grasp.

Instead of falling to the ground, it hovered in mid-air, its blade emitting an eerie red glow.

At the same time, the blue light spot also shimmered with silver light.

The two forces collided, and the Broken Army roared continuously, as if it were about to explode at any moment.

A resolute glint flashed in Li Tian's eyes as he struggled to his feet. "Old buddy, I will never let you crumble! Hah!"

The remaining internal energy was poured into Po Jun, and the booming sound gradually subsided.

Suddenly, Po Jun rushed towards the blue light spot.

It was a little scared and moved back a bit.

"I'm not going to let you get away with this good stuff that I've got!" Li Tian pounced on him, grabbed him, and half of his body was instantly frozen.

Buzz, whoosh!

A strange heat emanated from Po Jun and shot onto the other side of his body.

Instantly, Li Tianyi was experiencing the extreme pleasure of being torn between ice and fire...

Ten minutes later.

Li Tianyi was so tormented that he didn't even have the strength to twitch his lower eyelashes.

"Hello, system!" he shouted in his mind.

"Ding! An extremely Yin object has been detected." The system's voice was gentler than usual. "Friendly reminder: Two options. First, fully activate your extremely Yang internal energy to completely expel it. Second, use the principles of Tai Chi to fuse the extremely Yang and extremely Yin elements and seal them within the Po Jun (破军) formation."

The system paused for a moment, then announced, "If this method fails, Po Jun will shatter, and the host will die!"

Li Tianyi's expression was solemn as he cautiously asked, "And it was successful?"

"If successful, Po Jun will be upgraded to level ten, transforming into a divine weapon!" The system smiled faintly. "Good luck!"

A surge of bio-electric current coursed through my body, and I could barely move my hands and feet.

Li Tianyi struggled to sit up, assumed a cultivation posture, and formed hand seals, chanting, "The Tao gives birth to One, One gives birth to Two, Two gives birth to Three, Three gives birth to all things. Yin and Yang constitute the Tao, Yin and Yang constitute Taiji..."

Gradually, he entered a meditative state.

The two incompatible forces are still clashing, but their destructive power has been greatly reduced.

Several hours later, the two auras began to merge for the first time, and an unprecedentedly terrifying power surged outwards, instantly shattering a boulder into fragments.

The gravel shattered again, leaving powder everywhere.

The fusion of Yin and Yang energies accelerated, filling the surroundings with an even more terrifying aura, causing the ground to sink by nearly two meters.

Li Tianyi was unaware of these things and was still in a deep state of cultivation.

Buzz!

Half of the Po Jun axe turned crimson, while the other half became crystal clear.

Suddenly, Li Tianyi opened his eyes and formed a hand seal again, saying, "Man follows the Earth, Earth follows Heaven, Heaven follows the Dao, and the Dao follows Nature."

Surrounded by Yin and Yang energies, Po Jun began to merge with them, making a buzzing sound.

It is unknown how much time passed, but the Yin and Yang energies completely disappeared, and Po Jun returned to his original form.

"Ding! Po Jun has successfully advanced to level 10. (Experience points: 453,000 / 7,000,000)"

Li Tianyi was overjoyed. Holding the Po Jun sword, a feeling of perfect harmony spread throughout his body, bringing him indescribable comfort.

With a gentle sway, the yang energy enveloped the yin energy, making it extremely domineering.

Boom! Thud!

The small hill directly in front of us was cleaved in two with a single stroke.

"Holy crap!" Li Tianyi was so shocked that he couldn't come to his senses for a long time. "Even a casual strike has such terrifying power. If he were to unleash his full power, wouldn't it be just like a cultivation technique?"

Just as they were envisioning their world-destroying power, the protective shield in the distance suddenly shattered.

"ah!"

"Watch out! Get out of the way, quick!"

Wei Zheng and the others were terrified and rushed towards where Li Tianyi was...
