Gravel island is a place that can't compete with the eight poles of deception. The island is located 13700 miles northwest of deception. It is close to the corner of the famous "Canglang sea" in the cold world. However, it is often attacked by violent sea winds and waves, and almost no one is close to the harsh environment.

Moreover, compared with other places at sea, the marine resources here are pitiful and there are no precious products. Even mercenaries hunting at sea will not choose this less competitive place to hunt.

Tang Lichuan drove Tianxiang day and night. In a few days, he came over the gravel island.

Looking down, most of the gravel islands marked on the map have been submerged in the sea. Only the higher peaks are exposed. It seems that they have just experienced a big tide covering the whole gravel island.

The array mage killed by Qi Tianyi only left a clue of the place name, and the detailed place was not mentioned at all.

It is impossible to determine where the array is located on the island. It may be located on the seabed near the island. It is difficult to search without accurate orientation.

Suspended in the air, Tang Lichuan first let go of his perception and tried to scan. The scope of the island was not too large. It didn't take long to scan.

It's reasonable to get nothing. Since the transmission outlet of Decepticon fort is set here, with Qi Tianyi's cautious character, it can't be known by outsiders. He can even go to death with his own brother. He will never let others know the secret of the outlet.

People like him will not trust anyone. Even his confidants may not be qualified to know the exact location of the exit.

Then the exit is unlikely to be guarded by guards. To cover up the location of the exit, other methods will be used to cover up and shield an essential part of perception.

Tang Lichuan's perception scanned the island for a while and did not find any suspicious place on the island. Then he threw his perception into the sea area near the island and searched it carefully. It lasted a day and a night. Fang Yuanbai checked himself, but there was still no whereabouts of the transmission array.

This is an expected result. Dare to build the transmission array in a place that others can easily touch. If there were no clever means of concealment, Decepticon would have been attacked by people using this transmission array.

Tang Lichuan was not in a hurry because the perceptual search was invalid. Before he came, he thought of the possibility of the array being covered up. With a smile, he directly felt a round fat mouse from his sleeve.

"There is no guard here, that is to say, no one will often change the array energy, so the place where the array is located must have prepared a lot of energy materials, otherwise the array energy will be lost naturally, and it can't be started without energy at the critical time."

Gently stroking the little fat mouse in his hand, Tang Lichuan said with a smile: "this' golden treasure mouse 'has a very sharp sense of Reiki, and can see through a certain degree of magic. As long as you find a large number of places where Reiki exists and screen them, I believe you can find the location of the transmission array."

Tang Lichuan bought the treasure hunting monster commonly used by the mercenary regiment from the square city in advance. Although this place must have been explored countless times by others, Tang Lichuan still didn't give up using this method.

Up to now, Decepticon is still an iron bucket, which shows that the transmission array set up on gravel island has not been exposed. Why can't Tang Lichuan try this method.

The little fat mouse was fed a flower bean that he liked best. The little fat mouse immediately squeaked with joy. Then Tang Lichuan gently put it on the ground. The little fat mouse sniffed nearby, and then quickly went straight into the water. It seemed that there was a place with strong energy fluctuation nearby.

The little fat mouse went deep into the water. Tang Lichuan picked up a water shield and followed it slowly.

After swimming for a while, the little fat mouse stopped and looked around. It seemed that he was not sure about the specific location of Reiki fluctuation. He needed to stop and confirm it after searching for a while.

After about an hour, the little fat mouse and Tang Lichuan have left the scope of gravel island. Their current position has begun to swim towards the shallow area of canglanghai.

"Squeak!"

The little fat mouse swam and suddenly stopped vigilantly, staring at the bottom of the sea in horror.

This is a shallow sea. The light can also shine on the bottom of the sea. There is only a layer of thick and soft silt. There seems to be something under the silt.

"It's just a monster sea snake in the Yuan Wu territory, and it doesn't take the initiative to attack. Why does the golden mouse stop here?"

Tang Lichuan thought for a moment. With his right hand pointing at the sea snake under the mud, a thunderbolt burst out, and a blood hole was drilled in the head of the sea snake monster.

A smell of blood drifted away, and the monster in the Yuan Wu realm was easily killed in the mud by him.

However, after killing the monster, the golden treasure mouse not only didn't stop its fear, but hurriedly swam towards Tang Lichuan. Just now it was just a little afraid, and now it was completely scared and ran away.

Tang Lichuan stared at the mud below. He saw countless bubbles rising from the mud. There was a hole in each place where the bubbles appeared. The small ones were only the thickness of the thumb, while the large ones were the size of the mouth of a bowl. All the holes emitted a faint evil spirit. It seemed that the quiet water was actually the hiding place of sea snakes, More than 10000 sea snakes of different sizes are hidden in a small area that can be seen by the naked eye!

"Monsters usually like to build nests in places with strong aura. There are so many sea snakes here. It is very likely that there is a gathering place of aura below."

Tang Lichuan did not retreat but fell down. Ignoring the sea snakes who "hissed" at him, he directly scanned his perception towards the interior of a snake nest.

Under the gaze of perception, he found that the solid soil under the mud covered on the surface had been hollowed out. The sea snakes in front of him were only a small part of the guard. The place deep into the ground was an underground nest with countless holes and covering a wide area, and there were almost no less than a million sea snakes inside.

But one thing is very strange, that is, the lower his perception is, the weaker the effect is. If calculated according to the people in the general tianwu realm, their perception is basically unable to penetrate the camouflage nest 30 meters underground.

"It's very likely that the transmission array is here! Qi Tianyi thought of repairing the transmission array in the sea and borrowing the worthless sea snake nest as a cover up?"

Tang Lichuan shook his head and smiled. His body gathered Xuanli and suddenly accelerated towards a snake cave with a large entrance. The sea snake no less than the size of two rice bowls in the cave was directly knocked into meat mud by Tang Lichuan.

The impact shook the snake nest below. In the dark and matte underground world, bursts of creepy whistling spread, and the chaotic and distant echo was like a ghost singing
