After a few breaths, the arrow hole, which was originally only the thickness of a thumb, suddenly began to tremble, and then a trace of cracks began to bloom.

The arrow hole is expanding, constantly expanding, rapidly expanding, just in the blink of an eye, it has expanded dozens of times, and it is almost as thick as an adult's waist.

At the moment when the expansion of the arrow hole reached its limit, a dazzling golden light suddenly penetrated from the extremely deep seabed, like a fast-swimming golden snake, and suddenly rushed out of the sea and straight into the sky.

"Hiss!" The sound of spatial cracking faintly echoed in the sky above the sea, and then the golden light burst, and the huge hole formed by the arrow hole began to twist and rotate, forming a slender and powerful water vortex, and countless weak underwater creatures were pulled by this vortex force, and were thrown out of the sea in an instant.

But the moment they touched the surface of the sea, the invisible net showed its power again, and these underwater creatures that came like a torrential rain were all intercepted on the surface of the sea, and quickly dissolved into nothingness at a terrifying speed.

Lu Qingyu roughly estimated that such a large impact force was not weaker than the combined strength of the two sharks fighting just now, but even so, it was still not able to pull these creatures out of the sea, which shows that the invisible prohibition on the sea surface does have a great restrictive effect on these underwater creatures.

After reaching a positive conclusion, Lu Qingyu's thoughts began to turn sharply, since there is this layer of prohibition, then this seemingly endless sea has a premise that can be crossed.

As long as you find a way to build a ferry that can carry you, it doesn't seem impossible to leave this calm ocean.

Of course, the premise is that the right materials must be found, otherwise this plan is just a fantasy on paper.

Lu Qingyu looked around, it was impossible to find some materials for shipbuilding on this bare isolated island, and although there were a lot of things stored in the spirit bead, there was not much wood in it.

Think about it, who would carry a lot of wood with them, although the storage space in the spirit bead is not small now, it is impossible for Lu Qingyu to squander it so wantonly.

But no matter how annoyed it is now, it is useless, Lu Qingyu pondered for a while, since there is no hope for a small boat or something, then it should still be possible to make a simple sampan or something, it is necessary to build it simply, cut corners, as long as it can barely carry people, otherwise it is not a way to sit on this isolated island all the time, you have to try it!

Just do it, Lu Qingyu directly took the spirit bead off his wrist, and then shook it desperately, and suddenly some of the wood stored in the spirit bead that was originally used for camping was dumped and piled up into a small stack, which looked quite a lot, at least a lot more than Lu Qingyu expected.

Ha, this is going down, Lu Qingyu rubbed his hands excitedly, he didn't expect that some of the materials he usually collected by accident would come in handy at this time, which is really surprising!

Lu Qingyu, who was a little proud, didn't say a word, and quickly rolled up his sleeves and began to process the large pile of wood at his feet, although the materials were limited and the tools were limited, but with his superb strength, Lu Qingyu still quickly carried out the project.

The Ethereal Blade is used to chop wood, and the subtle realm helps to connect small materials in order to make the most of the limited materials, and in this way, in a few moments, the rudiments of a small sampan are revealed.

Although these methods are really overkill for building ships, Lu Qingyu is still full of a sense of achievement, after all, he has never done carpentry work, and it is indeed not easy for him to carry out the project so smoothly.

About half an hour later, Lu Qingyu's first carpenter career ended with a successful work.

Looking at the small sampan in front of him, which was sloping from side to side and rough in workmanship, but generally complete, Lu Qingyu smiled with satisfaction, and then couldn't wait to push it into the water.

Before the sampan was completely in the water, Lu Qingyu couldn't wait to jump into the air, ready to jump directly into the sampan and start moving towards the other side of the sea.

Unexpectedly, as soon as the sampan touched the surface of the water, it became like paper paste, and instantly became wet, and then began to become wrinkled and contracted, and in a short time it was foaming and sinking to the bottom.

Lu Qingyu, who jumped high, was caught off guard and suddenly fell into the water in a hurry, although the sea water on the shore was very shallow, but the defenseless Lu Qingyu still managed to make himself a soup chicken.

"Phew!" Lu Qingyu turned over and jumped up from the water, and after spitting a few mouthfuls of seawater, he ran back to the island in three or two steps.

Looking at the empty sea, Lu Qingyu suddenly felt a little angry, the sampan that had been built for half a day died inexplicably, and there was no reason for heaven!

Lu Qingyu stomped his feet angrily, grabbed some leftover scraps on the shore and threw them on the sea, and as a result, after these scattered pieces of wood came into contact with the seawater, they once again foamed and disappeared without a trace in the blink of an eye.

Seeing this, Lu Qingyu's eyes widened, and he was speechless for a moment, how can there be a reason that wood can't float on the water, this sea water is also a little weird!

But no matter how aggrieved Lu Qingyu was in his heart, it was a fact that the sampan was gone, and the hope of crossing the sea by wooden boat was also a fact.

However, what kind of method should be used to cross these three layers?

The prohibition on the sea surface can definitely be used, and this is probably the only way to get through the third layer, but how to use it is the right one, it is really a little weird, and some of it makes Lu Qingyu puzzled.

Along the way, Lu Qingyu didn't find any traces of Qing Ruo and Ji Steward, presumably they must have been far ahead, do they have any secret to passing through here quickly, since others can pass, then there must be some undiscovered tricks here, you must think about it.

Lu Qingyu was born with a bullish temper, and it stands to reason that he has gained a lot, even if he activates the teleportation array now and leaves the place of trial, it is nothing to do, but it has never been his style to retreat in the face of difficulties, so he would rather spend more time than give up the hope of crossing the sea easily.

It's just that even Lu Qingyu himself didn't expect that his time would be a month!

For a month, for thirty days, Lu Qingyu sat on the shore of the isolated island, except for the occasional food to stand up and walk, he was like a still sculpture and never moved a little.

But it's a pity that even though Lu Qingyu spent so much time and so much energy, the opportunity to cross the sea still didn't appear.

After all, not everything in the world can be solved with time and perseverance, and sometimes things like an epiphany are more important.

Just after Lu Qingyu sat for a full thirty days, Lu Qingyu finally felt a trace of despair and helplessness, he had thought about all the possibilities, and tried all the methods he could, but there was still no progress.

If there is still no gain in this kind of perseverance, then this perseverance is no longer a valuable quality worthy of praise, but seems to be a little futile and vain.

Since he really didn't have this opportunity, it was pointless to force it, Lu Qingyu had always acted decisively, and he had done his best in a month's time, since he still got nothing after all, he simply chose to give up.

This time he has made good achievements in the treasure exploration journey of the Land of Trials, at least now he is very close to the Venerable Realm, once he reaches the Venerable Realm, then whether it is to return to the Qingshui Country to rescue Qingyi or go to the Black Dragon Mountain to find Kong Dongyang will become feasible.

It seems that he has to find a way to travel around the continent again, after all, finding the remaining few pieces of spirit is the only way for him to improve his strength.

In addition, he can't stay longer in this Ruijin Kingdom, although Zhong Liang and Xu Gongzi died in the land of trials, and no one knows that it was his Lu Qingyu's hand, but nothing is absolute, in case this matter leaks out, then he will face the joint pursuit of the Zhong and Xu families.

These two represent the two most powerful organizations in the Ruijin Kingdom, and both have high-level Venerables in charge, this kind of strength is not something that Lu Qingyu can provoke at will now.

In this case, it seems that the next step should be to go to the Twilight Leaf Country or the Thick Earth Country to have a look, maybe you can gain something in these two unknown countries.

Thinking about his future plans, Lu Qingyu rubbed his legs and slowly stood up.

Taking a deep breath of fresh sea breeze, Lu Qingyu stretched a big lazy waist, although he had not found a way to cross the sea in the past month, he had completely recovered the injuries on his body, and he had also stabilized the strength that had improved by leaps and bounds a few days ago.

This rare retreat experience brought him a lot of benefits, but there were only a few regrets, after all, he knew with his toes that there must be more and more treasures in the next three layers of trials, but he was no longer qualified to compete for them.

"Huh?" After a lazy waist, Lu Qingyu faintly felt that his abdomen was pushed by something, as if it was a short hard object.

After reaching out and groping in his arms, Lu Qingyu quickly took out something.

Seeing this thing, Lu Qingyu's eyes suddenly lit up!

What did he see? ^-^^-^
