Traveling through time to cultivate immortality: a life and death test

The shark swam three quick circles around Jiao Jiao to express its gratitude. After the gift of the elixir and now the life-saving grace, the shark no longer held any grudges against Jiao Jiao, trusting her completely like a junior. The world of demonic beasts is simple and straightforward. Liu Xing, conditioned by his human mindset, over-constructed the demonic beasts. However, a little more foreshadowing is always a good thing. Jiao Jiao also appropriately expressed her trust in the shark, and the two demons prepared to explore the ocean together, supporting each other and striving for mutual progress. Then Jiao Jiao expressed her desire to see the shark's enemy, the leader, from afar, so she could memorize its appearance and presence, and seek revenge when they were stronger. The shark was deeply moved. This close friend, a friend through thick and thin, not only saved her life but also avenged her. Tears welled up in her eyes.

So, under Liu Xing's guidance, Jiao Jiao gradually learned the location of the shark leader's lair, its return patterns, and the defensive strength and vulnerabilities surrounding it. When this information reached Liu Xing, the shark leader's so-called defensive arrangements seemed like child's play—crude and full of loopholes. It's no wonder, then, that even a Level 4 demon beast possessed the intelligence of a six-year-old, it was still primarily driven by instinct. How could it possibly have a good defensive strategy? However, if a first-timer didn't understand the sharks' movements and rushed in rashly, they would be easily discovered. This was because the alerts weren't just coming from the sharks, but also from numerous other fish scouts, making it difficult to defend against them.

But now with the traitor, Shark Abandoned, everything became clear, and he knew everything about Jiao Jiao. Fearing Jiao Jiao would be in danger, Shark revealed everything, even helping her figure out how to avoid detection. He was certain Jiao Jiao was helping him, so he couldn't harm her.

So, led by the shark, the two demon gods arrived unnoticed at the shark leader's lair. It was an underwater canyon, and from afar, a vast cavern beneath the reef could be seen, covered in algae. It was truly hidden; without a guide, it would have been impossible to discover. The shark leader had a strong sense of territory, forbidding any demon beasts within a ten-kilometer radius of the cave, and any that strayed were slain. Over time, the only demon beast with cultivation here was the silver shark leader, though many other uncultivated fish swam about.

Jiao Jiao found a convenient excuse and released Liu Xing without anyone noticing. Liu Xing had already practiced the Turtle Breathing Technique and remained motionless, so the sharks didn't notice anything unusual. After watching for a while, the two demons left, planning to wait three days for the Silver Shark leader to return to his lair before taking another look from afar.

After a quarter of an hour, Liu Xing sensed that there was no more breath of monsters around, so he began to act. He first set up a huge "hiding trace" formation outside the cave, which was used to block the transmission of internal and external information during the battle. Then he went into the cave and began to study. The space inside the cave is very large, with a huge stone platform in the middle. The surface was polished smooth and translucent. It was probably the bed for the shark to lie down and rest. The stone platform looked dark, shiny and extremely hard. It was not an ordinary thing at first glance. With Liu Xing's knowledge, he did not recognize it as various minerals. In the corner of the cave, there was a shark-companion grass that was more than a thousand years old, which surprised Liu Xing. If he could get this spiritual herb, this trip would be worth it.

Liu Xing inspected the cave's actual conditions and set up a "Rising Tide" trapping array and two "Ten Thousand Swords Returning to the Origin" killing arrays along the stone platform. He finally felt relieved and didn't touch anything in the cave, to avoid being discovered by the Silver Shark leader and causing the ambush to fail.

He carefully inspected every area and rehearsed the battle scenario. Then he went into the deepest, darkest corner of the cave, sat cross-legged, and practiced the Tortoise Breathing Technique to conceal his entire body's magical energy, waiting motionlessly.

Jiao Jiao was helping him gather information from the perimeter. This time, she wouldn't be participating in the battle, primarily responsible for perimeter security. Once the battle began, if information leaked, she would be needed to prevent outside reinforcements. Should the mission fail or succeed, she would be responsible for providing support and a retreat, so Jiao Jiao had a heavy responsibility. Liu Xing also reminded Jiao Jiao to stay away from the cave residence for the time being, lest they be discovered and potentially cause the ambush to fail. If the Silver Shark leader were trapped in the barrier, Liu Xing would notify Jiao Jiao immediately, who would then come over and maintain security outside the cave residence. This arrangement was designed to minimize exposure and risk.

Five days later, the Silver Shark leader returned, exhausted. Arriving at the entrance to his cave, he felt an inexplicable palpitation, a sense of impending disaster. He was baffled. How could he possibly be in danger now that he was in his own cave? Could it be that the intense battle just now had left him feeling lingering fears? He carefully scanned his surroundings, finding no signs of change, so he dismissed the situation, swam inside, and rested on the stone platform. This time, he led his pack of sharks in a hunt against an orca, also a Level 4 demonic beast. The battle was brutal, with the sharks relentless, chasing for over a thousand miles before finally slaying the orca, even sacrificing one of their Foundation Establishment companions. However, the result was a significant one, and they ultimately emerged victorious. He opened his fins, revealing a Level 4 demonic elixir—the orca's own. He planned to rest for a while before refining it, figuring that refining it would significantly elevate his cultivation. As he was thinking, his eyes closed slightly and he actually started snoring.

Looking at the fourth-level demon core on the fin, Liu Xing suppressed his inner ecstasy, maintaining a calm demeanor to avoid betraying his presence. An hour later, the silver shark fell into a deep slumber. Liu Xing notified Jiao Jiao via his mind, then, with lightning speed, he activated four formations and simultaneously released five puppets, launching a concentrated attack on the silver shark leader.

The moment Liu Xing's aura emanated, Silver Shark was startled awake. By the time he sensed what was happening outside, the four formations had already activated. By the time he mobilized his mana to attack the intruder, the puppets' first wave of attacks had already closed in. He only had time to cast a protective aura shield before the five puppets, especially the powerful wooden ape's black iron staff, instantly shattered his shield.

Jiao Jiao, who was on the periphery, received the news and quickly rushed over with Silver Shark. Silver Shark was puzzled. Previously, when they urged Jiao Long, it had been hesitant and making various excuses to refuse. Now, for some unknown reason, it was rushing forward at top speed. However, Silver Shark did not suspect anything and quickly approached the cave residence. It stopped about seven or eight kilometers away and hid. This location was also the sentry point selected by the two demons.
