As Lin Yifan shouted, Tis immediately opened the secret passage. Forty thousand brave Red Ape warriors marched through the distorted space.

Moments later, the team appeared fifty kilometers outside the mine. As soon as he passed through the passage, Lin Yifan ordered someone to set up a high-power jammer, and under the interference of the interference wave, those night cats lost their reconnaissance ability.

The warriors of the Red Ape Clan were divided into four teams, Wang Xiaopang and Lin Nan led one team, Li Hu and Li Quan led one team, and Lin Yifan and the patriarch each led one team.

The team approached the mining site from four directions, and without the warning of the night cat, the team soon came to the vicinity of the mining site.

There were dozens of patrols of the Night Owl Clan in the grass outside the mine, and Lin Yifan was not in a hurry to kill them. Instead, let each brigade send two squads to sneak up from four different directions.

When these squads arrived at their designated positions, the four squads launched a surprise attack, attacking the patrols on the periphery at the same time with lightning speed.

Under the attack of new crossbows, bows, these patrols were quickly eliminated. However, the main reason for being able to eliminate so many patrols at once was that there were many warriors of the Red Ape Clan, and that they had been systematically trained for several months.

After eliminating the patrol, the Red Ape warriors immediately took off their Nightowl warrior costumes and continued their patrol disguised as them.

Lin Yifan and the others turned on the stealth system of the battle armor and sneaked into the cave through the four vents. The caves here are much more spacious than those in other mines, and they should have been expanded by the Sea Tribe.

The purpose of Lin Yifan and the others going in was to find a place where the Red Ape Clan was being held, and according to the current time, they should go to sleep.

Lin Yifan and the others searched cautiously, and after a while, they found the Red Ape Clan who was mining. However, they are not mining it now, but are transporting the mined ore to a warehouse outside the cave.

"What's going on over there?"

Lin Yifan asked.

"Boss! The red apes on my side have stopped mining. ”

"Captain Lin, so is my side!"

"Mr. Lin! My people are all transporting ore, and it looks like they're about to get out of work. ”

"The red ape people on my side are also transporting ore, everyone waits patiently for a while, and when they are ready to rest, they secretly follow and find the place where they are being held first."

Lin Yifan said.

"Good!"

Everyone responded in unison.

The Red Ape Tribesmen transported it for about an hour, and then saw them hand over their mining tools to the Night Cats, and then they lined up and walked towards the cave.

Lin Yifan and the others secretly followed behind the Red Ape Clan, and after passing through several narrow corridors, they came to a spacious cave.

This cave has been transformed by the Sea Tribes to look like a small palace. There were hundreds of rooms in the palace, each of which housed dozens of red ape people.

Seeing his clansmen's bruises, the anger in the patriarch's heart became more and more intense, and the crossbow and bow in his hand made a "creaking" sound when he held it.

"Patriarch, you must control your emotions and don't be impulsive."

Hearing the sound of the patriarch's breathing becoming more and more rapid in the communication channel, Lin Yifan hurriedly reminded.

"Good, good! Mr. Lin, don't worry, I will control it! ”

The patriarch took a few deep breaths, trying to suppress his anger.

Originally, Lin Yifan didn't want the patriarch to come when he went into the cave to reconnoitre, he was worried that the patriarch would be impulsive when he saw the tragic situation of the clansmen. But now it seems that it is not bad, at least these months of military training have not been in vain.

For this mission, Tis also created a set of armor specifically for the patriarch. However, this suit lacks advanced weapons, and only provides mobility and stealth for the chief.

Lin Yifan and the others waited quietly like this, and after ten minutes, all the Red Ape Clan people returned to the rest point.

"Mr. Lin! Most of my people are here, when will they be able to act? ”

The patriarch asked.

"Don't worry, they didn't send anyone to guard your clansmen, which means that there must be a detection system in this palace, wait for me to turn off the detection system first, and then start the operation."

Lin Yifan said.

"Good!"

The patriarch said.

There are five entrances to the palace, one of which is a corridor leading to the barracks. The other four corridors lead to the mining area, and Lin Yifan and the others hid in the vents in the four corridors.

Lin Yifan suspected that the control room should be in the barracks, so he went down to the palace through the vents, and then secretly walked in the direction of the barracks.

The corridor leading to the barracks was very deep, and Lin Yifan walked for about five minutes. There was no detection system in the hallway, and at the end of the hallway was a small and spacious palace, though it was a little smaller than the one where the Aqui apes were being held.

There are also plenty of rooms, each with a dozen night owl people living in each room. Lin Yifan used perspective scanning to reconnoiter around, but he didn't find a single Sea Clan.

Lin Yifan felt that the barracks of the Sea Clan should not be in the cave, and it was likely to be near the entrance of the cave. In order to find out the strength of the Sea Clan, Lin Yifan walked towards the entrance of the cave again.

Lin Yifan returned to the vent, and then followed the vent to the entrance. Fortunately, these vents are connected, which also reduces Lin Yifan's troubles.

When I came to the entrance, I saw the Sea Clan elite, and there was a fork in the road two hundred meters away from the entrance.

Along the fork in the road, Lin Yifan finally found the barracks of the Sea Clan, although it is not as spacious as the small palace, but the living facilities inside are very high-end.

Thinking that these sea tribesmen are also very good at enjoying it, a broken cave is actually so luxuriously decorated by them.

There are a total of ten rooms in the hall, and each room contains ten Sea Clan elites. According to the formation of the Sea Tribe, this is exactly the number of people in a squad.

At this time, there were nine teams of Sea Clan elites resting inside, while another team was keeping vigil at the entrance of the cave, and there were also about four or five teams of Night Owl warriors.

"Everyone's on the move!"

Lin Yifan ordered.

"Yes!"

The patriarch said excitedly.

According to Lin Yifan's plan, no one could use the high-tech weapons of the battle armor. This is mainly because they don't want the Sea Clan to suspect that a high civilization is involved, otherwise they will send a large number of fleets to support, which is not conducive to Lin Yifan's secret mining.

Lin Yifan and others lit the fire in four different directions, and they put a plant prepared in advance into the vent.

When this plant is ignited, it produces a lot of smoke, and this smoke can make it difficult to breathe when inhaled.

The smoke quickly entered the barracks through the vents, and the warriors of the Night Cat and Sea Clan all coughed incessantly, and some of them choked on the smoke and rolled on the ground with their heads in their hands, looking very painful.

"Start attacking!"

With Lin Yifan's order, tens of thousands of soldiers on the periphery began to attack the entrance of the cave. This time, instead of rushing towards the entrance of the cave in a swarm, they used crossbows and bows to shoot rockets at the entrance of the cave on the periphery.

These rockets are also specially made, and the arrows are wrapped around that particular plant. Thousands of rockets shot into the hole at the same time, and soon the hole was filled with clouds.

After inhaling the thick fog, the patrolmen guarding the entrance to the cave began to cough violently. Some of those with poor physique quickly suffocated to death, and those with good physique also lost their combat effectiveness.

And at this moment, the melee warriors of the Red Ape Clan rushed forward. They swung their spears and stabbed the patrol in the chest.

The warriors of the Red Ape Clan were all in high spirits, and they all released the anger in their hearts at this time. In less than ten minutes of attacking, all the guards at the entrance of the cave were killed by the Red Ape warriors.

Seeing the corpses of the enemy all over the ground, the warriors of the Red Ape Clan cheered loudly. This was the first time they had fought without losing a single soldier, which also made them respect Lin Yifan and the others even more.

When the entrance to the cave was attacked, the Sea Clan sounded the alarm. As soon as the alarm sounded, the automatic defense inside the cave was turned on.

Soon, the fog in the two barracks was drained, and the soldiers who had fallen and rolled on the ground also eased.

These Sea Clan elites were indeed extraordinary, as soon as the mist disappeared, they immediately turned on the defense of the battle armor, and then rushed towards the outside of the cave.

However, the Night Owl warriors were not so lucky, they did not have the armor of the Sea Clan, and it took them a five-minute delay to recover from their pain.
