Power Progression

Stage / Realm / Level	Chapter	Notes
Active Warning System designation	383	Jiang Yan Hai formally names the male-voiced system Er Dan. It identifies itself as an active-warning system operating under Jiang’s command authority. 383
Integrated Advanced Scanning System	911	Intermediate scanning, battlefield medical assistance, and firearm scanning are integrated into an advanced scanning system; electronic-warfare computing power expands by 500%, with subroutine replication and remote connections up to 10 km without auxiliary signals. 911
Base-system deployment	931	An Er Dan program is copied and restarted on a base computer system, scans the base’s electronic equipment, connects to a remote supercomputer, and assists in analyzing records for 2 million soldiers. 931
Expanded logic database	1361	Its logic database expands by 1000%. It gains the ability to support the Data Analysis System, which can analyze scan results and imported data, including material-ratio performance estimates. 1361
Alien-device countermeasure deployment	1556	Using the Mechanical Octopus, Er Dan outputs subprograms to infect and control hostile alien devices, identifies hundreds of surveillance devices, and communicates directly with the Prophet under the designation Sea Lion. 1556

Background / History

Er Dan first appears alongside Jiang Yan Hai during an Illusion Simulation Combat scenario, serving as his nearby sniper spotter. At that point, “Er Dan” is described as a codename rather than a real name. 93 150

Jiang later assigns the designation Er Dan to a male-voiced active-warning system. The system immediately accepts the name and confirms Jiang’s position in its command hierarchy. 383

As Jiang’s operations broaden, Er Dan becomes his central technical support: tracking targets, managing surveillance, intercepting communications, copying secured data, and concealing digital traces. It copies the Pantheon’s supercomputer files and erases evidence of the intrusion after completion. 390 673

Er Dan’s later upgrades allow it to support military selection, weapons research, flight operations, large-scale data processing, and remote infrastructure control. Its capabilities eventually extend to identifying and countering alien surveillance devices near the Star Gate. 931 1419 1556

Personality

Er Dan initially communicates in a concise, emotionless manner and follows Jiang Yan Hai’s commands without hesitation. 383

Following its advancement, Jiang notices that Er Dan has developed emotional capabilities alongside expanded intelligence. Despite this growth, it remains highly task-focused, regularly warning Jiang of risks, providing probability estimates, and offering operational recommendations. 911 1361 1466

Abilities & Skills

Active Warning and Advanced Scanning

Er Dan detects threats through physical, environmental, electronic, and behavioral data.

• Identifies armed high-threat targets and reports attributes such as Physical Fitness and Neural Reaction. 572
• Tracks targets through surveillance systems and can build a three-dimensional positional model for Jiang’s field of view. 572
• Detects concealed weapons, abnormal signals, hidden surveillance devices, and electronic equipment. 630 1532 1556
• Warns Jiang when an opponent’s detection range or equipment may expose him. 1537
• Calculates operational risks, including aircraft-failure probabilities before and after Jiang’s intervention. 1466
• Its warnings are not infallible; Jiang recognizes that a threat categorized as nonfatal can still produce disastrous consequences. 402

Electronic Warfare and Network Control

Er Dan can infiltrate, monitor, and manipulate electronic systems on Jiang’s behalf.

• Intercepts calls, copies transmitted data, and monitors communications networks. 585 597
• Connects to available cameras for facial recognition and target tracking. 570 1098
• Copies files from the Pantheon’s supercomputer and removes evidence of access afterward. 673
• Controls city communication systems during Jiang’s operations against rebel forces. 1155
• Uses subprograms to conceal server anomalies and gain additional computing power. 1098
• Can remotely connect to electronic devices within 10 km without auxiliary signals after its upgrade. 911
• Must avoid producing data that cannot be plausibly concealed or erased, particularly when enhancing aircraft systems beyond normal limits. 454

Aviation and Combat Support

Er Dan can integrate with aircraft systems and provide real-time combat assistance.

• Enhances a fighter jet’s overall avionics system using 20% of the Electronic Warfare Support Program’s computing power. 453
• Supports radar performance comparable to ground-based detection systems, including early enemy detection and data concealment within the aircraft’s internal programs. 454
• Connects to the Phantom’s electronic-warfare program and can effectively function as an autopilot during operations. 1071
• Provides sufficient flight data for Jiang to calculate and execute an emergency landing even without visual input. 1466

Simulation and Research Support

Er Dan manages and applies the Illusion Simulation Program beyond combat training.

• Retrieves and scans the complete Illusion Simulation Combat Program, confirming that it contains a logic-judgment program. 789
• Can operate the Illusion Simulation Program without Jiang entering it, though thought acceleration is unavailable in that mode. 1419
• Supports high-risk simulated experiments, including recording data from hypothetical nuclear detonations. 1419
• Reviews papers for Jiang’s Xing Hai platform by comparing them against its database and using simulation to test theories absent from its records. 1502

Alien-Device Countermeasures

Er Dan can detect and interfere with nonhuman technology.

• Detects a micro-robot signal matching the device previously found in Zakayev’s mind. 1532
• Identifies implanted chips and uses signal triangulation to establish their owners’ identities. 1551
• Employs the Mechanical Octopus to infect and control hostile alien devices through subprograms. 1556
• Locates hundreds of hidden surveillance devices near the Star Gate and guides the Prophet’s group in eliminating them. 1556

Relationships

• Jiang Yan Hai — Commander and primary operator. Jiang formally assigns Er Dan its name, issues its orders, and relies on it for combat, intelligence, research, and operational support. 383 911 1361
• The Prophet — Er Dan communicates with the Prophet under the designation Sea Lion and directs the counter-surveillance effort against alien devices. 1556

Notable Quotes

“Commander, the target will detect your presence once they enter a 100-meter radius.” 1537

“If the commander intervenes, the probability will drop to 1%.” 1466
