Drip...... Drip...... Drip...... Drip ......"

When the secondary alarm sounded inside the base, the forerunner immediately contacted the intelligence brain in the command center.

"Brain, report the situation!"

"Your Excellency, the submarine early warning radar we deployed offshore has detected some strange fluctuations, suspected to be Decepticons!"

Submarine radar was first deployed on the seabed around Trindadi Island to detect submarines of various countries that are increasingly active in the nearby waters.

Later, with the invasion of the replica warriors, when they summarized after the war, Sun Cheng and the others found that there were too many problems in the security defense system on the island.

As a result, the island's defense system was completely upgraded.

The submarine detection radar originally deployed in the surrounding waters to reconnoiter submarines of human countries is also being upgraded.

After several months of technological upgrades, radar is now deployed not only in the waters around Trindaddy Island, but also around several other islands.

The new submarine radar can not only detect submarines operating in the surrounding waters, but also include a variety of deep-sea unmanned detection devices that have begun to emerge in recent years.

Even the Decepticons and Autobots can be detected by undersea radar.

However, due to a series of reasons, although the submarine radar can detect a range of 470 kilometers, if you want to determine the identity of the Decepticons and Autobots, you must wait until the other party enters the best detection area of the radar, that is, within 130 kilometers, to determine the identity of the other party.

As soon as the forerunner heard Zhi Brain's speculation, a fierce color immediately appeared on his face.

"Send me the coordinates and more specific information, and at the same time monitor closely and update my data in real time!"

"Yes, Your Excellency, Commander!"

As for the suspicious intruder found by the intelligent brain speculation, it is likely to be the Decepticons, and the forerunners still agree with it.

They still have some cooperation with the Autobots, although the presence of predators makes the alliance between them and the Autobots less stable.

However, at present, the Autobots on the earth are basically only active in Africa, with the Decepticon Legion on their side, as long as Optimus Prime is okay, even if the Predators become the leader of the Autobots again, they should not be the first to sneak up on them.

The forerunner is still waiting for more accurate data from the submarine radar, but he is not waiting for the flagship, and he has not done anything.

Sun Cheng entrusted him with the responsibility of the black market, and the forerunner was the supreme commander here, with management responsibilities including overseeing day-to-day, security and defense.

Cautiously, he also began to give a quick order while waiting: "Control center, release two submarine unmanned probes to the northwest sea, coordinates xxxx direction!" ”

"Roger, Your Excellency Commander, the submarine unmanned probe will be released in three minutes!"

"Dash, you lead a team of Decepticon warriors and immediately go to the Dumar Reef area to temporarily keep on guard! The submarine radar was in the direction of the coordinates xxxx in the northwest sea, and some strange fluctuations were captured. ”

The dash was the first time that the Replica Warriors invaded Trindaddy Island and led the Decepticon warriors to come to their aid.

After changing to a new mech, he is now a high-level warrior, and he was also left on the island by Sun Cheng, and he is one of the most important combat forces under the Precursor.

After confirming that it was the Precursor in the communication channel, the dash immediately replied: "Roger, Your Excellency, Commander, I will take a group of soldiers to Dumar to be on guard!" ”

The Dumar Reef Zone is a group of reef rings located about seven kilometers north of the island of Trindadadi, and the largest of them is just over 600 square meters.

Some of the remaining reefs are only a few dozen to two or three hundred square meters above the sea, and because the area is too small to have development value, these reefs are not usually within the scope of daily patrols.

So once there is an intruder, this area will easily become a breach.

After giving the safest order, the Precursor waited patiently.

After the release of the two submarine unmanned probes, the ability of the Trindadi sub-base to explore the target sea area has been rapidly improved.

The unmanned detectors are somewhat similar to submarines, but they are much smaller, each weighing only about 30 tons, and equipped with a powerful detection and video system.

It can dive to a maximum depth of 5,000 meters and reach a maximum speed of 84 knots.

In order to prevent being attacked or eaten by large sea creatures on the seabed, the unmanned detector is equipped with a small cannon that can shoot a special steel gun with a diameter of about 11 centimeters and a length of nearly three meters when threatened.

Because it was propelled at full power, the probe quickly entered and drove hundreds of kilometers, and was about to make contact with an unknown target in the rapid approach.

Then the next moment, an alarm sounded immediately in the control center of the sub-base on the island, and at the same time, the forerunners also received a notification.

"Your Excellency, Commander, we have lost contact with the probes."

The Precursor's fists clenched violently, and there was a crackling sound of metal scraping.

"Did you shoot or detect anything?"

"Nothing was found, and the data transmitted back at the end showed that the other side had at least launched a missile dozens of kilometers away and hit our unmanned reconnaissance vehicle."

In an instant, the forerunners understood.

"Enemy attack!"

He gave the order in a deep voice, but his voice was full of war.

"Wait for my orders, ready to sound the alarm at any time."

"All the Decepticon warriors on the island, start assembling at once."

"Control center, ready to release smart mines!"

"Notify the nearby patrol ghost fleet, transmit the exact coordinates to them, and order the torpedo to be released immediately into the target area!"

For the attack that may come from the direction of the seabed, Sun Cheng has already considered it before, and some targeted arrangements have been made.

However, the complexity of the seabed dooms them to be more passive than the intruder in the face of an invasion from the seabed.

The Precursors quickly realized this, but he had to wait patiently until more precise information arrived.

Soon, the island's central master control brain processed the data captured by the submarine radar and immediately transmitted it to the forerunners.

"Your Excellency, the latest data has been processed. Radar detected seventeen intruders and identified them as Decepticons. ”

Almost at the same time, a dull explosion resounded in the sea hundreds of kilometers away.

The Precursor snorted, "I see, continue to wait for my orders, there is no need to sound the alarm until you get my orders." ”

Seventeen invading Decepticons are just that, although the strength of the other side is not clear.

However, the Precursors were confident that they would be able to repel it with the strength of the island's current garrison.

He quickly rushed towards the northwest of the island, and as the commander of the Trindadi sub-base, he was also the main fighting force here.

Now, it's time to fight.
