He Yuzhu walked along the main road to Tresia Town. It was about two kilometers away, and he arrived in just over ten minutes. According to the records of the two maps and the excavation of later generations, he was still prepared to start digging from the vent of Teresa 2, which was also the vent of the former president of the country of Philo in 1975. It was the breakthrough point chosen by Si's people when digging.
However, they had only opened the treasure vault of " Teresa No. 2." They had not found the other four treasure spots. Perhaps they had found them but did not let the news leak. However, his harvest on the Teresa 2 was still huge. He had harvested more than 2,000 tons of gold alone.
However, He Yuzhu was much better than Ma Ke. Fortunately, he had the detailed map left behind by the chief engineer of the treasure vault before he died. Ten meters southwest of the vent they had dug, there was a straight road. It was not completely sealed, only twenty feet from top to bottom.
The ventilation hole they dug was easy to find. It was marked as a reference point. It was behind a huge mango tree. Because it was only filled with gravel and soil, according to the records in the book, there were also the corpses of the prisoners of war. In this tropical rainforest, there was some settlement, forming a circular depression in the ground.
He Yuzhu walked along the mountain forest and circled around Tresia Town. It was already getting late. The day here was nearly 13 hours in August. It was almost 7 p. m. and the sun only set. When He Yuzhu found the reference object, it was already past 8 p. m. There was no entertainment in the town. The residents had all gone home and closed their doors to rest.
He Yuzhu followed the blueprint and found the location of the vent reserved by the Japanese pirates. He took out an engineering shovel and scraped the fallen leaves and floating soil to the side. As expected, he saw a shallow depression. This pot-shaped depression was only about 1.5 meters in diameter. In theory, it was impossible to move the gold and jewelry out of this passage.
However, He Yuzhu was a man with a BUG. He only needed a passage that could allow one person to enter and exit, and he could empty the treasure vault. He returned the fallen leaves to their original state and released a camouflage tent from the dent.
Of course, this camouflage could not be compared to the digital camouflage of the future. It was just a simple mottled camouflage, but it still had a certain concealment effect.
After setting up the tent, He Yuzhu picked up the pickaxe and the shovel and started digging. What was better than other people's digging was that he only needed to loosen the soil with the pickaxe, insert the shovel, and move the soil into his Dimensional Pocket. His speed was naturally extremely fast.
He Yuzhu was still thinking as he dug. This engineering shovel was really not powerful. Later on, he would make the future generation's multi-functional engineering shovel so that our soldiers could have an easier time digging trenches.
At this moment, the shovel is still very simple. After the second generation of shovels is designed, our soldiers haven't replaced the first generation shovels because there are too many in stock.
As he thought about it, he tried his best to dig down. In less than an hour, he dug up a steel plate.
After He Yuzhu put the steel plate into his Dimensional Pocket, he realized that the soil and rocks below were easier to dig. It was probably because they had not settled and compressed. By the time dawn arrived, He Yuzhu had already dug four to five meters deep. He looked at the time on his watch and climbed back to the ground. He took out a camouflage net from the military supplies he had obtained and fixed it on the steel plate.
He took a lot of dead branches and leaves from a distance and fixed them on the camouflage net bit by bit. When he laid them flat, they did not look much different from the surroundings. Of course, he could still find them when he got closer. He laid the steel plate flat to cover the hole, leaving a few ventilation holes, and restored the surrounding area to its original state.
He used his Dimensional Pocket to retrieve the steel plate, bent down, and jumped into the hole he had dug out. Then, he placed the steel plate back on the ground. This way, he would be working underground and would not be discovered from afar.
One had to know that many residents of Tresia Town made a living by quarrying stones in the mountains. Although this place was hundreds of meters away from the road up the mountain, if one paid a little attention, they would be able to find the tent. After all, the camouflage in this era was too simple.
He Yuzhu cleared the surrounding soil first. Last night, he had rushed to dig deeper. He had to dig out a space to hide himself first. Now, he had to consider the safety issue. He did not want the soil above to fall and bury him when he reached the bottom.
After clearing the surroundings to the stone wall, the sky brightened. He Yuzhu returned to the Portable Space, ate, bathed, and slept. After resting for half a day, he ate something and then left the Portable Space in high spirits. However, he was hit the moment he came out. The cave was abnormally hot and humid.
He flashed back into his space and took off his military uniform. He continued digging in his shorts and tank top. About two hours later, when his pickaxe smashed down, he heard a thud again. He dug into another steel plate. He Yuzhu knew that the upper part was about to be dug through.
He cleaned up the surrounding soil and found that there was a stone platform on both sides that could allow one person to stand. He stood on the stone platform on one side and put the steel plate into his Dimensional Pocket. As expected, there was a deep black hole below.
He Yuzhu did not dare to go down immediately. He knew that the oxygen below was very thin, and he could not work there. He had worked in the real estate industry for more than 20 years in his previous life. He knew that the manual digging piles used in building houses also relied on manpower to dig down. When they dug up to ten meters, there would be a lack of oxygen, and a fan had to be used to send air down.
This tunnel was more than 60 meters deep, so the construction difficulty would definitely be much higher. He put the steel plate back in its original position and entered the Dimensional Pocket. He wanted to let the deep hole go through first. He also wanted to look for something useful in the supplies of the rotten army.
As he rummaged through, he thought that it would be good if there was diving equipment. However, he remembered that he did not get any frogman diving equipment in the Mei Army's arsenal. He suddenly remembered that there seemed to be oxygen equipment in the medical supplies. He quickly went to the medical supplies to look for it. It was troublesome to have too many things. He Yuzhu thought that he had to find time to clean up these supplies.
From the medical supplies, he found an oxygen supply device. This oxygen tank was too big. He was still thinking about the portable oxygen supply devices in the future, such as the small oxygen tanks with masks that were held in hand when hiking or traveling to high-altitude areas. The medical oxygen tanks in this period were almost as tall as him.
However, he had no choice but to keep one on hand. The air below had been blocked for a long time, and the air must be dirty. He took out a gas mask and carefully observed to see if he could connect the oxygen tube, but these two things could not be equipped together.
Unlike the gas masks used by the firefighters in the future, the medical oxygen used a very thin tube and was directly connected to the oxygen mask. However, according to the records, there were more than 2,000 prisoners of war buried below. Not only was there a lack of oxygen, but there was also a high possibility that there was a large amount of toxic gas. Therefore, the gas mask could not be taken off.
He Yuzhu thought about it and decided to put on the medical oxygen mask first, then put on the gas mask to give himself double insurance. He tried it out. Although it hurt his face, it was still passable.
He first put these things aside and left the Dimensional Pocket. He put away the steel plate and tied the fixed steel ring on the stone platform with a rope. He held his breath and slid directly to the bottom of the cave.
When he reached the bottom, he quickly took out the gas mask and oxygen tank from his Dimensional Pocket. He put on the breathing mask and took a few deep breaths before putting on the gas mask and starting to work.
