Lin Yu also swam back quickly, but it was really laborious. There seemed to be a huge force under the vortex, forming a strong suction force.
"This whirlpool seems to be somewhat spiritual!" the old man shouted.
Lin Yu used all his strength to swim towards a safe area. But the whirlpool was also chasing after him. Wherever Lin Yu swam, the latter followed him.
"It's so difficult!" Lin Yu looked back at the whirlpool and complained.
"Just find a place and go back first!" the old man shouted again.
Lin Yu also knew in his heart that if he continued to be entangled like this, his physical strength would eventually be exhausted and he would eventually die in the lake.
Lin Yu hurriedly activated his source energy again and used the psychic barrier to block the vortex.
The vortex was also cut off by the wall of air, so Lin Yu had no choice but to leave.
"Huh..." Lin Yu climbed to the shore of the mountain, breathing heavily.
"This barrier is really easy to use!" Along the way, this psychic barrier trick indeed saved Lin Yu in many critical moments.
"Take this time as a lesson. Try it again when you are ugly." The old man reminded kindly.
"That vortex seems to have some spirituality. How to avoid it?" Lin Yu felt distressed as he recalled the huge suction force.
"This is actually a difficult problem!" The old man also sighed.
"The vortex seems to be guarding the treasure box!" Lin Yu also noticed this. As long as he approached the treasure box, the suction force of the vortex would become stronger and stronger.
Lin Yu and the old man also fell into silence, thinking about how to avoid the whirlpool.
"..., old man! Do you think you can use the speed source energy and the psychic barrier together?" Lin Yu suddenly broke the silence, seeming to have an idea.
"Oh? How to use it?" The old man was also interested in Lin Yu's idea.
"Use his body skills to lead the whirlpool far away from the treasure, then use the psychic barrier to block it, and finally gather the speed source energy on his body to get the treasure box!" Lin Yu said unhurriedly , the aura is full of confidence.
"..., you little kid is quite smart, but I'm afraid you only have thirty seconds to go!" The old man also marveled at Lin Yu's intelligence, but was worried that he didn't have enough time.
"I've thought about this too, but right now there's no better way than this." Lin Yu said firmly.
"Good boy! Let's do it!" The old man's tone also became more firm.
After that, Lin Yu also took a rest. This time, Do didn't rest for long, so he concentrated on practicing.
Finally, the color of the day changed a little, and the moonlight became brighter and brighter.
"Okay! It's time!" Lin Yu opened his eyes, looked at the same strange movement in the center of the lake as before, stood up, and rushed towards it.
"Good boy!" The old man said silently in his heart again.
Lin Yu also quickly reached the depths of the lake. As he approached the treasure box, he indeed disturbed the whirlpool again.
But this time Lin Yu was very calm and slowly guided the vortex according to his own plan.
"Ha..." Lin Yu also sneered when he saw this.
Lin Yu and the whirlpool were seen arriving on the west side of the lake. Lin Yu looked around with his eyes, and after confirming the distance, he turned his palms to gather his source energy.
The latter also responded quickly and erected an air wall to block the vortex. Lin Yu also quickly jumped away, his whole body exuding light blue light.
Lin Yu's speed also surprised the old man, "This kid can actually control that speed source energy to such an extent."
Lin Yu was very fast and reached the treasure box in less than half the time.
Although there was no whirlpool for the time being, there were still boulders rising from the bottom of the lake, and Lin Yu still had to be careful.
Lin Yu also hurriedly activated his source energy to split the water plants wrapped around him.
At this time, the strength of the air wall was getting weaker and weaker, and the vortex rushed out towards Lin Yu.
"It's so heavy!" Lin Yu used both hands to lift the treasure box, but found that it was unusually heavy.
"Boy, that whirlpool!" the old man shouted quickly.
"Retreat quickly!" The old man shouted loudly again, indicating that Lin Yu was in danger.
But Lin Yu ignored the old man's words and still tried hard.
"Boy! Run! There will be a last chance tomorrow!" The old man increased his tone and roared.
"Get up...!" In an instant, the treasure box seemed to be awakened by a huge force, and Lin Yu shouted angrily with veins popping out.
That scene also shocked the old man, and his heart trembled.
After Lin Yu lifted the treasure box, he saw that the whirlpool was about to hit, but it rushed back to the shore at an extremely fast speed.
As Lin Yu moved, his eyes gradually became bloodshot, which was very impressive.
Lin Yu carried the treasure box to the shore, his eyes sank, and he dropped it heavily to the ground.
"Boy? How could..." the old man also shouted.
The night was getting darker and darker, and the lake finally calmed down, and everything seemed to be slowly returning to normal.
Lin Yu tried his best to open his eyes and feel everything around him.
"Boy, are you finally awake?" the old man whispered.
"..., I am..." Lin Yu felt that his body was extremely tired. He seemed to have exhausted all his strength at the bottom of the lake just now.
"You really don't want your life! If you were a little careless just now, I'm afraid you will lose your life." The old man shouted with a complaining attitude.
"I... don't know either." Lin Yu's consciousness was also very vague. He seemed to be a different person at the moment when he was in the lake.
"But fortunately, the result is good." Lin Yu said slowly. At that moment, he felt so tired even talking.
"The mission can be considered successfully completed. You should have a good rest first. It's too late to rush on the road early." The old man said.
"That treasure box... what's in it?" Lin Yu was also curious about the contents of the treasure box.
"The treasure box has a mechanism set up. I'm afraid only members of the Lin family can open it." The old man also checked the treasure box when Lin Yu was asleep.
"Is it the Lin family again..." Lin Yu also snorted coldly, closed his eyes and fell asleep.
"This boy... really has the same courage as his parents back then. Good boy, I will definitely help you find your parents and ask about the matter." The old man thought secretly in his heart.
"After the clan is full this time, your journey will probably be longer!" the old man said with a smile.
On that day, the sound of cicadas by the lake also woke Lin Yu up. The entire lake was as clear as a mirror, completely different from the previous situation.
"Okay! It's time to return!" Lin Yu whispered.
